The data below represents the number of medals won by the top ten countries in the 2014
Winter Olympics. If the mean is 20.4 and the standard deviation is 7.9, circle all values that
fall within one standard deviation of the mean.
6, 11, 15, 17, 19, 24, 25, 26, 28, 33
Answer:
You should circle:
15, 17, 19, 24, 25, 26, 28
Step-by-step explanation:
The values x that falls within 1 standard deviation of the mean are those which.
[tex]|x - 20.4| \leq 7.9[/tex]
6
|6 - 20.4| = 14.4 > 7.9
6 is not within 1 standard deviation of the mean.
11
|11 - 20.4| = 9.4 > 7.9
11 is not within 1 standard deviation of the mean.
15
|15 - 20.4| = 5.4 < 7.9
15 is within 1 standard deviation of the mean.
17
|17 - 20.4| = 3.4 < 7.9
17 is within 1 standard deviation of the mean.
19
|19 - 20.4| = 1.4 < 7.9
19 is within 1 standard deviation of the mean.
24
|24 - 20.4| = 3.6 < 7.9
24 is within 1 standard deviation of the mean.
25
|25 - 20.4| = 4.6 < 7.9
25 is within 1 standard deviation of the mean.
26
|26 - 20.4| = 5.6 < 7.9
26 is within 1 standard deviation of the mean.
28
|28 - 20.4| = 7.6 < 7.9
28 is within 1 standard deviation of the mean.
33
|33 - 20.4| = 12.6 > 7.9
33 is not within 1 standard deviation of the mean.

What is the base of a triangle with area 50 squared inches and height 3/4 inches to the nearest hundredth?
Answer:
66 2/3 inches
Step-by-step explanation:
The area formula needed here is A = (1/2)(base)(height).
Here A = 50 in^2 and (height) = 3/4 in. We must find the length of the base.
Multiplying both sides of A = (1/2)(base)(height) by 2, we get 2A = (base)(height), or
2A 50 in^2
(base) = -------------- = ----------------- = 66 2/3 inches
(height) 0.75 in

Answer:
area- 150 , height-12 , base-25
Step-by-step explanation:
multiply the base times height then divide by 2
Answer: The height of the triangle is 12 cm. The base of the triangle is 25 cm. The area of the triangle.... formula: multiply base by height then divide by 2......
so, 25 times 12(height) then divide by 2
Therefore the area is 150 cm.

Two rectangular prisms, M and N, are mathematically similar. The volumes of M and N are 17 3 and 136 3, respectively. The height of N is 18 . Find the corresponding height of M.
Answer:
9 cm
Step-by-step explanation:
Volume of M= 17cm^3. Volume of N=136cm^3
Volume of N/Volume of M = k^3
136/17=8
Cube root of 8 =2
Now we know that k=2.
Height of N/2 =height of M
18/2= 9
Therefore, the height of M=9

If the ratio of children to adults is 2:9 and there are 70 children at an arts festival, how many adults are in attendance?
Answer
How to enter your answer
adults
Answer:
315
Step-by-step explanation:
If 70 children is 2 parts, one part is 35
35*9 is 315
Answer:
315 adults
Step-by-step explanation:
2:9 where 2 is children and 9 is adults.
2 = 70, therefore 1 = 35
35 x 9 = 315
Express the following ratio in simplest form $0.45 : $4.50
Answer:
1 : 10
Step-by-step explanation:
Miranda and Savannah are excited that a new store just opened in town! They go together the first day it opens!
Each time Miranda goes to the store she plans to spend \$7dollar sign, 7, and each time Savannah goes to the store she plans to spend \$9 dollar sign, 9.
A few weeks from now, Miranda and Savannah are surprised to find out that they have spent the exact same total amount of money at the store.
What is the least possible number of times that Miranda has been to the store?
Answer:
9
Step-by-step explanation:
Given that
Spending done by Miranda each time while go to the store = $7
Spending done by Savannah each time while go to the store = $9
For computing the least possible number we need to take the least common multiple of $7 and $9 i.e to be $63
Now the lease possible number for Miranda has been to the store is
[tex]= \frac{ Lease\ common\ multiple}{Spending\ done \ by\ miranda}[/tex]
[tex]= \frac{\$63}{\$7}[/tex]
= 9
Or we can do one thing as we know that 7 is a prime number which is not cut by any other number except one while the 9 factor could be [tex]= 3\times 3[/tex]
Therefore the 9 times would be considered
An experiment is broken up into two parts. In the first part of the experiment, a six-sided die is rolled. In the second part of the experiment, a dime is tossed in the air. What is the probability of landing on tails?
Answer:
The answer is %50.
Step-by-step explanation:
Since the rolling of the six-sided die and the tossing of the dime are seperate events, their probabilities do not affect each other. Therefore the probability of the dime landing on tails should be %50.

Pushpin, a social networking site, sent out a survey to all female users. One of the questions in 2014 was, "Do you cook dinner every day?" More than 35,000 women responded, with 38% responding yes. What can you conclude from the survey?
Answer:
We can conclude that of the women who responded to the survey, most of them stated that they do not cook dinner every day. However, it is important to note that there is not much more to be concluded because there are a lot of factors that can go into this. For example, to push feminist perspectives, women may lie about them cooking or be more inclined to respond to the survey (voluntary response bias). Furthermore, women who cook may be less likely to be on the site
Answer:
Undercoverage occurred, so the results tell us little about the population of all adults.
Explanation:
This was targeted to social networking site females, this excludes the population of females who do not use social networking or are unable to. Hope this helps

If the factors of quadratic function g are (x − 7) and (x + 3), what are the zeros of function g?
A.
-7 and -3
B.
-3 and 7
C.
3 and 7
D.
-7 and 3
Answer:
The correct option is (b).
Step-by-step explanation:
We are given with the factors of quadratic function. They are as follows :
(x − 7) and (x + 3)
It is required to find the zeroes of function g.
To find zeroes of function, it is required to put the factors equal to 0 i.e.
[tex](x-7)=0\\\\x=7[/tex]
and
[tex](x+3)=0\\\\x=-3[/tex]
From above calculations, we can say that the zeroes of function g are 7 and (-3). Hence, the correct option is (b).

So I have another trigonometry question PLZ HELP ME I'm clueless at this rate I have like a little idea but I'm lost, SO PLZZZ! I NEED IT BY JUNE 4
1. Lifeguard stands on a beach are approximately 300 ft apart. They are at 30-degree angles to a windsurfer on the water in between them. How far away is the windsurfer from each tower. Draw a diagram to help you picture the situation.
2. If the Earth is approximately 93 million miles from the sun, and Mercury is about 36 million miles from the sun, what are the possible distances between Earth and Mercury on a certain day if the angle between the sun and mercury is 22 degrees as measured from Earth?
Answer:
1) The windsurfer is approximately 580 ft from each lifeguard stand.
2) The distance between the Earth and Mercury is approximately 61 million miles.
Step-by-step explanation:
The image other two situations described is presented in the attached image to this answer.
1) From the attached image, the windsurfer forms a right angled triangle with each of the lifeguard stand and the midpoint between the two lifeguard stands.
Hence, the angle at the top of the triangle is half of 30°, 15° and the distance from the midpoint of the lifeguard stands to the lifeguard stands is 300/2 = 150 ft.
Let the required distance of the windsurfer from each of the lifeguard stands be x.
Using trigonometric relations,
Sin 15° = (150/x)
x = 150 ÷ sin 15° = 150 ÷ 0.2588
x = 579.6 ft = 580 ft to the nearest whole number
2) From the image, the Sun, Earth and Mercury form a triangle.
Let the possible distance between the Earth and Mercury be y.
Using cosine rule,
y² = 36² + 93² - (2×36×93×cos 22°)
y² = 3,736.5769098208
y = √3,736.5769098208 = 61.13 million miles = 61 million miles to the nearest million miles.
Hope this Helps!!!
