The diameter of a circle is 16 in. Find its circumference in terms of \piπ.
Answer:
50.24
Step-by-step explanation:
The formula for solving circumference is 2 x pi x r
first the radius is 8 (divide 16 by 2 and get radius)
( pi can be 22/7 or 3.14. but I’m taking 3.14 )
second, we have all values, now we just have to substitute them!
Pi = 3.14
R = 8
so when we do 2x 3.14 x 8 = 50.24
I hope this helped!
Answer: The area of the circle is 64π cm
Step-by-step explanation:
d=16→r=8
A= π⋅8 ^2
A= π⋅64
A=64π
The Seattle Space Needle casts a 67-meter shadow. If the angle of elevation
from the tip of the shadow to the top of the Space Needle is 70°, how tall
the Space Needle? Round to the nearest meter.
Answer:
The space needle is 62.95 m tall.
Step-by-step explanation:
Given that,
The height of the shadow, h = 67 m
The angle of elevation from the tip of the shadow to the top of the Space Needle is 70°.
We need to find the height of the space needle.
The shadow of space needle is hypotenuse of right angled triangle. Let the height of the space needle is x m. Using trigonometry,
[tex]\sin\theta=\dfrac{x}{h}\\\\x=h\times \sin\theta\\\\x=67\times \sin(70)\\\\x=62.95\ m[/tex]
So, the space needle is 62.95 m tall.

What is another name for the height of a pyramid?
A. Length
B. Width
C. Altitude
O D. Lateral face
SUBMIT
Answer:
Altitude
Step-by-step explanation:
Find another name for the height of a prism or a pyramid.
Since we know that the height of a prism or pyramid is the perpendicular distance between the two ends of a prism or pyramid.
We can find the height of the pyramid by dropping an altitude from the top of the pyramid to the base of the pyramid.
Note to moderators:
Please don't delete this answer because I'm just trying to help others.
The height of the pyramid is also called the altitude of the pyramid. Since both of these terms represent the same thing, we can use the two terms interchangeably. The correct option is C.
What is pyramid?A pyramid geometry is defined as a three dimensional object with a polygon as its base and the triangles forms the lateral faces which meet at a point above the base called the apex. The pyramids have different parts and some of these parts have more than one name.
The height of the pyramid indicate the perpendicular distance from the base of the pyramid to the apex of the pyramid. This line segment which is perpendicular to the base and runs from the base to the apex is defined as the altitude of the pyramid.
Based on the shape of the base, the pyramids are of many types like triangular pyramid, square pyramid, etc.
Thus the correct option is C.

Look at the triangle shown below.
107º
(2x - 5)º
xº
Which equation can be used to find the value of x?
O x + 2x - 5 = 107
O 107 + 2x - 5 = 180
107 + 2x - 5 + x = 180
X + 2x -5 = 180
Answer:
C. 107 + 2x - 5 + x = 180
Step-by-step explanation:
The sum of interior angles of a triangle = 180°
Therefore, to find x, we would state that all three angels indicated in the figure above equals 180°.
Thus:
107 + 2x - 5 + x = 180
We can solve and find the value of x using the equation above
Answer:
C
Step-by-step explanation:
Which equation is the slope intercept form of this equation?
y - 4 = -2 (x – 5)
a- x = - 2y + 3
b- 2x + y = 6
c- y = -2x + 14
d- y – 4 = -2x + 10
Answer:
C
Step-by-step explanation:
Y - 4 = -2x + 10 Multiply -2 to the inside the brackets
Y = -2x + 14 Add the 4 over

California's traffic People love living in California for many reasons , but traffic isn't one of them . Based on a random sample of 572 employed California adults, a 90 % confidence interval for average travel time to work for all employed California adults is 23 minutes to 26 minutes
(A) Interpret the confidence level
(B) Name two things you could do to reduce the margin of error. What drawbacks do these actions have?
(C) Describe how no responses might lead to bias in this survey.Does the stated margin of error account for this possible bias?
90% of all samples have a confidence interval that contains the right average travel time for all employed adults in California.
What is a confidence interval?Increased Sample Size: This provides more information about the population and allows us to calculate an accurate estimate. Data collection is expensive and time-consuming.
Decrease in Confidence Level: Confidence interval having correct population interval is less confident. It has fewer possible values for true population parameters. Hence, it is less confident about the confidence interval has the correct population parameters.
Non-Response Bias
Nonresponse bias happens when there isn't enough data for everyone in the sample. People whose data is unavailable lead to bias and over- or underestimate the true population. The margin of error is not used because it merely takes potential variation into consideration.

Suppose that a recent poll found that 47% of adults believe that the overall state of moral values is poor. For 350 randomly selected adults, compute the mean and standard deviation of the random variable X, the number of adults who believe that the overall state of moral values is poor. What is the mean of X and the standard deviation of X?
Answer:
The mean of X is 164.5 and the standard deviation is 9.34.
Step-by-step explanation:
For each adult, there are only two possible outcomes. Either they believe that the overall state of moral values is poor, or they do not. The probability of an adult believing this is independent of any other adult, which means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
[tex]E(X) = np[/tex]
The standard deviation of the binomial distribution is:
[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]
Suppose that a recent poll found that 47% of adults believe that the overall state of moral values is poor.
This means that [tex]p = 0.47[/tex]
350 randomly selected adults
This means that [tex]n = 350[/tex]
What is the mean of X and the standard deviation of X?
Mean:
[tex]E(X) = np = 350*0.47 = 164.5[/tex]
Standard deviation:
[tex]\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{350*0.47*0.53} = 9.34[/tex]
The mean of X is 164.5 and the standard deviation is 9.34.

The length of RT is 14
Step-by-step explanation:
For a given Right Triangle
m∠R = 90°, RG = 17, TG = 22
Now, By Pythagoras Theorem
(RT)² + (RG)² = (TG)²
(RT)² = (TG)² - (RG)²
(RT)² = (22)² - (17)²
(RT)² = 484 - 289
(RT)² = 195
RT = √195
RT = √195 = 13.96 = 14
Thus, The length of RT is 14
