4. On the last three physics exams a student scored 87, 85, and 91. What score must the student earn on the next exam to have an average of at least 90?
The student must score at least enter your response here%
In the given question, the rocket will hit the ground in 7 seconds. The width of the rectangle is 3 cm. Kirk makes the wall in 5.5 hours. The student needs 97 marks.
The relation between the height and the time of the toy rocket has been given in the question as,
h = -4.9t²+33.6t + 4.9
where,
h= height of the rocket after getting launched
t= time after which the rocket has been launched
So, if we have to calculate how much time the rocket takes to reach the ground,
we have to take h=0 (at ground).
So, the equation becomes
0 = -4.9t²+33.6t + 4.9
Now, the roots of this equation will give the time at which the rocket will hit the ground.
So, after calculating we get
t = -0.1428 sec
or
t = 7 sec
since negative time is not possible,
the time at which the rocket will hit the ground is 7 seconds.
The length of the rectangle is = 5b-7 cm
Hence, the area is = b(5b-7) = 24
Hence, the width comes out to be = 3 cm
Kirk would be able to make the wall in 5.5 hours. This is because Jeff can make it one hour earlier than him i.e., K-1 hours. So, we get -
= (K-1) + K = 10
= 2K = 11
= K = 5.5 hours
The student already has 87 + 85 + 91 = 263 marks. He needs at least -

If the inflation rate was 3% last year and John's salary grew 4%, how much did the purchasing power of his salary change?
John's purchasing power increased by 0.97%.
What is the inflation?
The definition of inflation in the field of economics is "mean increased money supply, but the general public often refer to a sustained increase in the general price level of goods and services in an economy over a period".
If the inflation rate was 3% and John's salary grew 4%, his salary increased more than the rate of inflation. However, his real increase in purchasing power depends on the difference between his salary growth rate and the inflation rate.
To calculate the change in John's purchasing power, we can use the following formula:
Change in purchasing power = (1 + Salary growth rate) / (1 + Inflation rate) - 1
Plugging in the values, we get:
Change in purchasing power = (1 + 0.04) / (1 + 0.03) - 1
Change in purchasing power = 1.01 / 1.03 - 1
Change in purchasing power = 0.0097 or 0.97%

Write the standard form of the equation of each line.
1) y=3x+1
2) y=-9/5x+3
helppppp plsssss
Answer:
Step-by-step explanation:
(1)To write this in standard form, we want the x and y terms on the same side of the equation and the constant on the other side. To do this, we can subtract 3x from both sides:
-3x + y = 1
So the standard form of the equation is:
-3x + y = 1
(2)y = -9/5x + 3
To write this in standard form, we want to eliminate the fraction by multiplying both sides by the denominator (5):
5y = -9x + 15
Next, we can move the x term to the left side by adding 9x to both sides:
9x + 5y = 15
So the standard form of the equation is:
9x + 5y = 15
Evaluate the triple integral xy dV where E is the solid tetrahedon with vertices (0,0,0), (9,0,0), (0,8,0), (0,0,6)
The value of the triple integral xy dV over the solid tetrahedron with vertices (0,0,0), (9,0,0), (0,8,0), and (0,0,6) is approximately 490.5. The limits of integration for x, y, and z are 0 to 9, 0 to 8 - (8/9)x, and 0 to 6 - (1/3)x - (1/4)y, respectively.
To evaluate the triple integral, we need to set up the limits of integration for the three variables x, y, and z. Since the solid is a tetrahedron with vertices at (0,0,0), (9,0,0), (0,8,0), and (0,0,6), we can write the limits of integration as follows:
0 ≤ x ≤ 9
0 ≤ y ≤ 8 - (8/9)x
0 ≤ z ≤ 6 - (1/3)x - (1/4)y
The limits of integration for x are straightforward, as x ranges from 0 to 9. For y, we need to consider that the solid is bounded by the x-axis (y=0), the y-axis (x=0), and two planes that intersect along the line x=9, y=8. The equation of the plane containing the points (0,8,0), (9,0,0), and (0,0,6) is given by 8x/9 + 6z/9 = 8, which simplifies to y = 8 - (8/9)x - (2/3)z. Solving for z, we get z = (3/2)(4 - (3/4)x - (3/4)y), so the limits of integration for z depend on both x and y.
With these limits of integration, we can set up the triple integral as follows:
∭E xy dV = ∫0⁹ ∫0(⁸-(⁸/⁹)ˣ) ∫0(⁶-(¹/³)ˣ-(¹/⁴)ʸ) xy dz dy dx
Evaluating the innermost integral with respect to z, we get:
∫0(⁶-(¹/³)ˣ-(¹/⁴)ʸ) xy dz = xyz |z=0 to z=(6-(1/3)x-(1/4)y) = x y (6 - (1/3)x - (1/4)y)
Substituting this expression back into the triple integral and evaluating the remaining integrals, we get:
∭E xy dV = ∫0⁹ ∫0(⁸-(⁸/⁹)ˣ) x y (6 - (1/3)x - (1/4)y) dy dx
= ∫0⁹ x [(3/4)y²(8/9 - (1/3)x) - (1/12)y³(8/9 - (1/3)x)] |y=0 to y=(8-(8/9)x) dx
= ∫0⁹ x [(3/4)(8/9 - (1/3)x)³ - (1/12)(8/9 - (1/3)x)⁴] dx
≈ 490.5
Therefore, the value of the triple integral is approximately 490.5

Therefore, there are 142,506 different committees of 5 students that can be selected from a group of 30 students.
What is Probability ?Probability is a branch of mathematics that deals with the study of random events and the likelihood of their occurrence. It is a measure of the chance or likelihood of an event happening, expressed as a number between 0 and 1. A probability of 0 means the event will not occur, and a probability of 1 means the event will definitely occur.
The probability of an event can be calculated by dividing the number of favorable outcomes by the total number of possible outcomes. This is known as the classical probability, and it assumes that all outcomes are equally likely.
There are also other types of probability, including empirical probability (based on observations and data), subjective probability (based on personal judgment and beliefs), and conditional probability (the probability of an event given that another event has occurred).
Probability has applications in many fields, including statistics, science, finance, and engineering. It is used to model and predict the occurrence of events, to make decisions under uncertainty, and to design systems and processes that can minimize risk and maximize the chances of success.

Jeff has a sack full of marbles. Each time he picks one out, he puts it back into the sack before drawing another. In his sack there are 5 red marbles, 6 yellow marbles, and 8 blue marbles. Find the following probabilities.
c. If two marbles are drawn, what's the chance they are both the same color?
d. If two marbles are drawn, what's the chance they are NOT the same color?
Therefore , the solution of the given problem of probability comes out to be P(not same color) = 236/361.
What precisely does the probability method suggest?Calculating the likelihood that a statement is true or that an event will take place is the focus of probability theory, a branch of mathematics. Any number range between 0 and 1, where 1 is frequently used to describe certainty and 0 is commonly used to denote possibility, can be used to represent chance. A probability diagram shows the likelihood that a particular event will occur.
Here,
There are three cases to consider:
Case 1: both marbles are red
Case 2: both marbles are yellow
Case 3: both marbles are blue
The probability of drawing two red marbles can be found by multiplying the probability of drawing a red marble on the first draw (5/19) by the probability of drawing a red marble on the second draw (5/19):
P(red and red) = (5/19) * (5/19) = 25/361
Similarly, the probability of drawing two yellow marbles is:
P(yellow and yellow) = (6/19) * (6/19) = 36/361
And the probability of drawing two blue marbles is:
P(blue and blue) = (8/19) * (8/19) = 64/361
So, the probability of drawing two marbles that are the same color is:
P(same color) = P(red and red) + P(yellow and yellow) + P(blue and blue)
P(same color) = (25/361) + (36/361) + (64/361)
P(same color) = 125/361
d. If two marbles are drawn, what's the chance they are NOT the same color?
There are three cases to consider:
Case 1: one marble is red and one marble is yellow
Case 2: one marble is red and one marble is blue
Case 3: one marble is yellow and one marble is blue
The probability of drawing one red marble and one yellow marble can be found by multiplying the probability of drawing a red marble on the first draw (5/19) by the probability of drawing a yellow marble on the second draw (6/19), and then multiplying by 2 (since the order of the marbles doesn't matter):
P(red and yellow) = 2 * (5/19) * (6/19) = 60/361
Similarly, the probability of drawing one red marble and one blue marble is:
P(red and blue) = 2 * (5/19) * (8/19) = 80/361
And the probability of drawing one yellow marble and one blue marble is:
P(yellow and blue) = 2 * (6/19) * (8/19) = 96/361
So, the probability of drawing two marbles that are not the same color is:
P(not same color) = P(red and yellow) + P(red and blue) + P(yellow and blue)
P(not same color) = (60/361) + (80/361) + (96/361)
P(not same color) = 236/361

An angle measures 23.6° less than the measure of its complementary angle. What is the measure of each angle?
Answer:
56.8 AND 33.2
Step-by-step explanation:
Complementary angles add up to 90 degrees, so we can set up the equation:
x + (x - 23.6) = 90
Simplifying the equation, we get:
2x - 23.6 = 90
Adding 23.6 to both sides, we get:
2x = 113.6
Dividing by 2, we get:
x = 56.8
So one angle measures 56.8 degrees, and its complementary angle measures:
90 - 56.8 = 33.2 degrees.

probability
(i) 61/2000
(ii) 9/2
(iii) 261/400
Total no. of drivers = 2000
(i) exactly 3 accidents (18-29 years of age)
[ P(E)= no. of favourable outcomes/total no.of Outcomes]
P(E) = 61/2000
(ii) one or more accidents in a year (30-50 years of age )
= 125 +60 + 22 + 18
= 225
P( E) = 225/ 2000
= 9/2
(iii) having no accidents in one year
= 440 +505 +360
= 1305
P(E) = 1305/2000
=261/400
hope it helps

Find the measure of angle of a, b, and c?
The measure of angle of a, b, and c are a = 90, b = 9- and c = 60 degrees
How to determine the measures of the anglesFrom the question, we have the following parameters that can be used in our computation:
The figure
The angle at the circumference in a semicircle is 90°
This means that
a = b = 90 degrees
Also, we have
Angle c and angle with a measure of 60 degrees are equal
This means that
Angle c = 60 degrees
Hence, the measure of the angles are a = 90, b = 9- and c = 60 degrees

Therefore , the solution of the given problem of triangle comes out to be ∠ADC = 100 and ∠DCB = 39 Degree.
What does a triangle actually mean?Given that they have three quadrants or more, triangles are considered polygons. It has a straightforward geometric shape. The letters ABC form a right-angled triangle when put together. Euclidean geometry creates a new rectangle of square when the borders are incompatible. Given that they have three sides and three corners, triangles are categorised as polygons. The corners of a triangle are determined by where its three sides meet. The sum of the angles inside a triangle is 180 degrees.
Here,
Given :
A triangle ADC and Triangle DCB
To find the angle :∠ADC and ∠DCB in the figure
So,
Acc to triangle angle sum property:
43 + 3y + 7 + 2x + 17 = 180
Simplifying, we get:
2x + 3y + 67 = 180
Subtracting 67 from both sides, we get:
2x + 3y = 113
and
61 + 3y - 13 + 4x - 1 = 180
4x + 3y + 47 = 180
4x + 3y = 133
2x + 3y = 113
4x + 3y = 133
-4x - 6y = -226
Adding this to the second equation, we get:
-3y = -93
Dividing both sides by -3, we get:
y = 31
Substituting this value of y into either equation, we can solve for x:
2x + 3(31) = 113
2x + 93 = 113
2x = 20
x = 10
Therefore, the solution is x = 10, y = 31.
Thus,
∠ADC = 3(31) + 7 = 93 + 7 = 100
∠DCB = 4(10) -1 = 40 -1 =39
