Answer:
37.69
Step-by-step explanation:
There are 3 circles
Circle A ( radius = 6 cm )
Circle B ( radius = 4 cm )
Circle C ( radius = 2 cm )
the circumference of a circle is C = 2 Pi x r
from each circle we need half of the circumference
Circle A : P = 2pi x 6 / 2 = 6 pi
Circle B : P = 2pi x 4 / 2 = 4 pi
Circle C : P = 2pi x 4 / 2 = 2 pi
the perimetee of the shaded shape is = 6 pi + 4 pi + 2 pi = 12 pi = 37.69 cm
Dion is performing a hypothesis test in which the population mean is 92 and the standard deviation is 2. His sample size is 7 with a mean of 93. 5. Which of the following correctly depicts the z-statistic for this data? 0. 28 0. 36 1. 98 2. 63.
The value of the z statistic for the considered data is given by: Option C: 1.98 approximately.
How to find the z score (z statistic) for the sample mean?If we're given that:
Sample mean = [tex]\overline{x}[/tex] Sample size = n Population mean = [tex]\mu[/tex] Sample standard deviation = sThen, we get:
[tex]z = \dfrac{\overline{x} - \mu}{s}[/tex]
If the sample standard deviation is not given, then we can estimate (in some cases) it by:
[tex]s = \dfrac{\sigma}{\sqrt{n}}[/tex]
where [tex]\sigma[/tex] = population standard deviation
For this case, we're specified that:
Sample mean = [tex]\overline{x}[/tex] = 93.5Sample size = n = 7Population mean = [tex]\mu[/tex] = 92Population standard deviation = [tex]\sigma[/tex] = 2Thus, the value of the z-statistic is evaluated as:
[tex]z = \dfrac{\overline{x} - \mu}{\sigma/\sqrt{n}} = \dfrac{93.5 - 92}{2/\sqrt{7}} \approx 1.98[/tex]
Thus, the value of the z statistic for the considered data is given by: Option C: 1.98 approximately.

Answer:
(a) 3x + 4 = 2x + 1
3x - 2x = 1 - 4
x = -3
Step-by-step explanation:
To solve for 'X', you must move all 'x' to the left-hand side, as seen through the working out. To balance it, you move all the lone numbers without (constants) to the right. Remember: when you move values across the 'equals' sign, the sign of the value you are moving becomes switched. For example, if you're moving 3x + 1 = 0 and you wish to move 1 to the other side, it becomes 3x = 0 ( - 1).

Answer:
The last answer [tex]\sqrt{65}[/tex]
Step-by-step explanation:
[tex]7^2+4^2 = 65[/tex]
The formula to find it is [tex]a^2+b^2=c^2[/tex]
so [tex]\sqrt{65}[/tex] is correct
Answer:
√65 ft (Option D)⠀
Step-by-step explanation:
This is Right Angled Triangle.⠀
We'll solve this using the Pythagorean Theorem.
⠀
AC = 7ft which is the Base. BC = 4 ft which is the Perpendicular. AB is the Hypotenuse.
⠀
We know that,
[tex]{ \longrightarrow \pmb{\qquad \: (AB) {}^{2} = (AC) {}^{2} + ( BC) {}^{2}}}[/tex]
⠀
[tex]{ \longrightarrow \sf{\qquad \: (AB) {}^{2} = (7) {}^{2} + ( 4) {}^{2}}}[/tex]
⠀
[tex]{ \longrightarrow \sf{\qquad \: (AB) {}^{2} = 49 + 16}}[/tex]
⠀
[tex]{ \longrightarrow \sf{\qquad \: (AB) {}^{2} = 65}}[/tex]
⠀
[tex]{ \longrightarrow \sf {\pmb {\qquad \: AB}}} = \pmb{ \frak{\sqrt{65}}}[/tex]

The length of the Hypotenuse (AB) is √65 ftWhich graph best represents the equation created when the slope of y = 6x is changed to 0?
The graph with an equation y = 6x has a slope of 6. If the slope is changed to 0, the equation becomes y = 0.

We see that Triangle ABC is an isosceles triangle which means:
Sides BA and BC are equal in lengthAngle BAC and BCA are equalWe see that Angle BCD and Angle BCA are on a straight line, which means that both of the angles' measures are equal to 180 degrees
--> in equation form:
Angle BCD + Angle BCA = 180
118 + Angle BCA = 180
Angle BCA = 62 degrees
Since Angle BCA and BAC are equal, then Angle BAC or Angle A in this case is 62 degrees

Assume that the following data were generated using a valid and appropriate methodology. XYZ Data Analytics, Inc. Received properly completed surveys from 523 members of the target population for a new product. One hundred seventy nine of those respondents indicated they would buy the new product at the proposed price
Using the z-distribution, as we are working with a proportion, the 95% confidence interval for the proportion of consumers who would buy the product at it's proposed price is (0.3016, 0.3830).
What is a confidence interval of proportions?A confidence interval of proportions is given by:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which:
[tex]\pi[/tex] is the sample proportion.z is the critical value.n is the sample size.In this problem, we have a 95% confidence level, hence[tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.
179 out of 523 members indicated they would buy the new product at the proposed price, hence:
[tex]\pi = \frac{179}{523} = 0.3423[/tex]
Then the bounds of the interval are found as follows:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3423 - 1.96\sqrt{\frac{0.3423(0.6577)}{523}} = 0.3016[/tex]
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3423 + 1.96\sqrt{\frac{0.3423(0.6577)}{523}} = 0.3830[/tex]

What is the turning point of a function?A stationary point is called a turning point if the derivative changes sign (from positive to negative, or vice versa) at that point.
There are two types of turning point:
A local maximum, the largest value of the function in the local region. A local minimum, the smallest value of the function in the local region.
Given are the coordinates of a function,
We need to find the turning point of the same,
Since we know that the function of the graph is continuous, then (-2, -1) is the most likely turning point because at this point the function stops increasing and starts decreasing.

Positive Numbers: If a number is greater than zero, it is considered positive. For instance, 1, 2, 3, etc.Negative numbers are those that are less than zero. For instance: 1, 2, 3, etc.Zero is described as being neither a positive nor a negative number. A whole number, that is.Given:
Two are scuba diving in the water, below sea level. One is swimming on the surface, at sea level.
We know that the the region below sea level represented by negative integers and the region above sea level represented by positive integers.
Thus, if the scuba driver is on the surface then it neither negative nor positive.
