We have the following system of equations,

[tex]\left \{ {{y=x^2-1} \atop {y=5-x}} \right.[/tex]

We are asked to solve the system of equations using substitution.

What is substitution?

Substitution is a method of solving a system of equations where you solve for one of the equations (pick either equation) for one of the variables (pick one of the variables), then using this new equation to "substitute" back in to the other.

Given this set of equations, [tex]\left \{ {{y=x^2-1} \atop {y=5-x}} \right.[/tex], notice how both of the equations are already solved for the variable, [tex]y[/tex]. Since both these equations equal [tex]y[/tex], we can set them equal to each other and solve for, [tex]x[/tex].

[tex]\left \{ {{y=x^2-1} \atop {y=5-x}} \right.[/tex]

[tex]\Longrightarrow 5-x=x^2-1[/tex], substituted "[tex]5-x[/tex]" for [tex]y[/tex] into the top equation.

[tex]\Longrightarrow -x^2-x+6=0[/tex]

[tex]-1[\Longrightarrow -x^2-x+6=0][/tex]

[tex]\Longrightarrow x^2+x-6=0[/tex]

[tex]\Longrightarrow (x-2)(x+3)=0[/tex]

[tex]\Longrightarrow x=2 \ and \ x=-3[/tex]

Now take these values of x ([tex]x=2 \ and \ x=-3[/tex]) and plug them into either of the two original equations to solve for [tex]y[/tex].

When x=2:

[tex]y=5-x;x=2[/tex]

[tex]\Longrightarrow y=5-(2)[/tex]

[tex]\Longrightarrow y=3[/tex]

When x=-3:

[tex]y=5-x;x=-3[/tex]

[tex]\Longrightarrow y=5-(-3)[/tex]

[tex]\Longrightarrow y=5+3[/tex]

[tex]\Longrightarrow y=8[/tex]

Thus, we get two solutions to the given system of equations, (-3,8) & (2,3).

The appropriate numerical measures of center and spread to describe a given distribution of a quantitative variable depend on the shape, symmetry, and presence of outliers in the data.

Measures of center include mean, median, and mode. The mean is affected by extreme values, while the median is resistant to outliers. The mode is useful when looking for the most common value or values in a distribution.

Measures of spread include range, interquartile range (IQR), variance, and standard deviation. The range is the difference between the maximum and minimum values, but it is sensitive to outliers. The IQR is the range of the middle 50% of the data and is resistant to outliers. Variance and standard deviation both measure the spread of the data around the mean, with the variance being the average squared deviation from the mean and the standard deviation being the square root of the variance.

In general, if the data is approximately symmetric and without outliers, the mean and standard deviation are appropriate measures of center and spread, respectively.

If the data is skewed or has outliers, the median and IQR are more appropriate. If the distribution has multiple modes, the mode may be useful to describe the distribution, but it should be used with caution as it may not be unique or well-defined for certain distributions.

Ultimately, the choice of measures of center and spread depends on the characteristics of the data and the research question being investigated. It is always a good practice to use multiple measures of center and spread and to visualize the distribution of the data using histograms or boxplots to gain a better understanding of the data.

Answer: The correct digits for the combination lock are 1, 5, and 8, in that order.

Step-by-step explanation:

Based on the given clues, we can deduce the correct digits for the combination lock as follows:

From the clue "128 One digit is right and in its place," we know that one of the digits is 1.

From the clue "157 One digit is right, but in the wrong place," we know that either 5 or 7 is a correct digit, but in the wrong position. Since we already know that one of the digits is 1, the correct digit must be 5. Therefore, the second digit is 5 and it is in the wrong place.

From the clue "841 Two digits are right but both are in the wrong place," we know that the digits 8 and 4 are correct, but they are both in the wrong position. Therefore, the last digit must be 4 or 8. However, we also know from the clue "624 One digit is right, but in the wrong place" that the last digit is not 4. Therefore, the correct third digit is 8.

So, the correct digits for the combination lock are 1, 5, and 8, in that order.

Therefore, the combination for the lock is 158.

Answer:

  120°

Step-by-step explanation:

You want to know the measure of the obtuse angle x° at B in the attached diagram.

This problem is quickly solved by using your knowledge of "special" triangles. Referring to the attached figure, triangles ACE and DGC are isosceles right triangles, so their base angles are 45°. Triangle CDE is equilateral, so all of its internal angles are 60°.

Line AB forms a "straight angle" at C. That means the sum of angles on one side of the line is 180°. This can be used to find the measure of angle DCB.

  ∠ACE +∠ECD +∠DCB = 180°

  45° +60° +∠DCB = 180°

  ∠DCB = 180° -105° = 75°

From above, you know that angle CDG is 45°.

The marked angle x° is an exterior angle to triangle BCD. As such, its measure is equal to the sum of the remote interior angles of that triangle:

  x° = ∠BCD +∠BDC = 75° +45°

  x° = 120°

__

Additional comment

As with many math problems there are other ways to work this. If you draw a perpendicular to AB at C, you find it makes a 45° angle with CE and a 15° angle with CD. That same 15° measure is the measure of angle GCB. Of course, angle G is 45°, so it takes x° = 120° to make the internal angle sum of ∆GCB equal to 180°.

Answer:

x > -8

The percent error for patricks estimate for the first day of school is 25%.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

We need to Write the percent as a fraction in simplest form

16.24%

So, we can rewrite it as;

16.24 / 100

16 and 24/100 or 16 6/25

So the percent as a fraction is 16 6/25

We are given that;

Time patrick took= 45min

To find the percent error, we first need to find the difference between Patrick's estimate and the actual time it took him to get ready.

Actual time - Estimated time = Error

45 minutes - 45 minutes = 0 minutes

The error is 0 minutes, which means Patrick's estimate was exactly right and there was no error.

However, if we assume that Patrick made a mistake when he estimated and that his actual time is the correct value, then we can find the percent error as follows:

Error = | Actual time - Estimated time | = | 45 minutes - 60 minutes | = 15 minutes

Percent error = (Error / Estimated time) x 100% = (15 minutes / 60 minutes) x 100% = 25%

Option b. 5. The number 125 can be written as 6 times 20 plus 5. Therefore, when x is 125, the expression "x % 6" evaluates to 5.

The adage "x % 6" signifies the rest of x is separated by 6. At the point when x is 125, the rest of 125 is partitioned by 6 can be found by playing out the accompanying whole number division:

125 ÷ 6 = 20 remaining portion 5

This implies that 125 can be composed as multiple times 20 in addition to 5. Consequently, when x is 125, the adage "x % 6" assesses to 5.

So the response is (b) 5.

At the point when we utilize the modulo administrator (%) to track down the rest of x partitioned by 6, the maxim "x % 6" assesses to 5 when x is 125. This is on the grounds that when 125 is separated by 6, the remainder is 20 with a rest of 5. At the end of the day, 125 is equivalent to multiple times 20 in addition to 5.

At 7 a.m., the temperature was 2°.

Temperature is a measure of the average kinetic energy of particles in a system, measured in degrees on a specific scale (such as Celsius or Fahrenheit). The higher the temperature, the faster the particles move. Temperature is also related to heat, which is the transfer of energy between two systems at different temperatures. Heat always flows from a higher temperature system to a lower temperature system. In addition, temperature is related to pressure, which is the force exerted by the particles in a system. When the temperature of a system increases, so does the pressure.

At 7 a.m., the temperature was 2°. This is because temperatures dropped by 2° per hour until 2 o'clock in the morning. In the 6 hours (from 2 a.m. to 8 a.m.) there were 12° of decrease in temperature (2° per hour x 6 hours). This means that the temperature at 7 a.m. was -6° (2° - 12° = -6°).

The missing side length, C, is approximately 23.53 units.

To find the missing side length in a right triangle, we need to use trigonometry. Given the angle A = 27° and the side length opposite to it, B = 12C, we can follow the following steps to find the missing side length:

1. Locate the angle measured: In this case, we are given angle "A = 27°."

2. Label the sides of the right triangle: Let's label the hypotenuse as H, the side opposite to angle A as O, and the side adjacent to angle A as A. We can choose any side as the hypotenuse, so let's choose H to be the side opposite to angle B.

3. Which side do you know? Which side are you trying to find?: We know the length of side B and are trying to find the length of side C.

4. Decide which trig function (cosine, sine, or tangent) fits the sides chosen in step 3: We are given the length of the opposite side (B) and are trying to find the length of the adjacent side (C), so we will use the tangent function.

5. Write your equation. Fill in the known measurements: The tangent of angle A is defined as the ratio of the length of the opposite side to the length of the adjacent side. So we can write:    tan(A) = B/C

      Substituting the known values, we get:

      tan(27°) = 12/C

6. Create two fractions. Cross-multiply to solve: To solve for C, we can cross-multiply and simplify the equation as follows:

      tan(27°) = 12/C  

      C * tan(27°) = 12          

      C = 12/tan(27°)                                                                                

        Using a calculator, we can evaluate the value of tan(27°) to be approximately 0.5095. Therefore,                                                     

       C = 12/0.5095 ≈ 23.53

Answer:

It will take about 13.5 years for the money to grow to $5,500
That would be about 13 years and 6 months

Step-by-step explanation:

The formula for accrued amount(principal + interest) is given by:
[tex]A = P\left(1 + \dfrac{r}{n}\right)^{nt}\quad(1)\\[/tex]

where
P = Principal amount
r = R/100 where R is the annual interest rate as a percentage
n= number of times compounded per year
t = number of years

Given

A = $5,600
P = $3,500
R = 3.35% ==> r = 3.35/100 = 0.0335
n = 12 (since there are 12 months in a year)

We have to find out t

Plugging known values into equation (1)

[tex]5500 = 3500\left(1+ \dfrac{0.0335}{12}\right)^{12t}\\\\5500 = 3500 \left(1+ 0.002791\right)^{12t}\\\\5500 = 3500 (1.002791)^{12t}[/tex]

Switch sides so unknown appears on the left side:
[tex]3500 (1.002791)^{12t} = 5500[/tex]

Divide by 3500 both sides:
[tex](1.002791)^{12t} = \dfrac{5500 }{3500}\\\\(1.002791)^{12t} = 1.5714\\\\[/tex]

Take logs on both sides:
[tex]\ln \left(1.002791^{12t}\right)=\ln \left(1.5714\right)\\\\[/tex]

We have
[tex]\ln \left(1.002791^{12t}\right) = 12t\ln \left(1.002791\right)\\\\[/tex]

Therefore we get
[tex]12t\ln \left(1.002791\right)=\ln \left(1.5714\right)\\\\t\ln \left(1.002791\right)=\ln \left(1.5714\right)\\\\\\[/tex]

Dividing both sides by [tex]12\ln \left(1.002791\right)[/tex] this works out to
[tex]t=\dfrac{\ln \left(1.5714\right)}{12\ln \left(1.002791\right)}[/tex]

[tex]t = 13.51359\; years[/tex]

Rounding to one decimal place
[tex]t = 13.51\; years\\[/tex]

This would be roughly 13 years and 6 months
