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
Answers
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.

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.
Answers
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

There are 20 students in a 5th grade class. Four of these students will be selected to be patrols. In how many ways can the four patrols be selected?
Answers
Answer:
4845 ways
Step-by-step explanation:
We need to form groups of four students among the total of 20 students, and the order of the students inside the group does not matter, so we have a combination problem.
To solve this problem, we just need to find the combination of 20 choose 4:
C(20, 4) = 20! / (16! * 4!) = 20 * 19 * 18 * 17 / (4 * 3 * 2) = 4845
There are 4845 ways of selecting this group of four patrols.

Find the volume of a cone with radius 12 yd and height 4 yd. Use 3.14 for π. Compare the volumes of the two cones. Use pencil and paper. Pick different values for the radius and height and calculate the volume of two cones like the ones described here. Compare the volumes of these cones.
Answers
Answer:
Volume is 602.88
Step-by-step explanation:
Here, we are asked to
calculate the volume of the cone.
Mathematically, to do this, we need to use the formula for finding the volume of cone= 1/3 * pi *r^2 * h
now we know that radius is 12 yards and height 4 yards. Plugging these values we have;
V = 1/3 * 3.14 * 12^2 * 4
V = 602.88 inches^3

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
Answers
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).
What is the base of a triangle with area 50 squared inches and height 3/4 inches to the nearest hundredth?
Answers
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

Mags is 2 years older than Vector. Which equation will
help you find Mags' age (m) if you know Vector's age (v)?
v = m + 2
m = V + 2
V-2=m
Answers
Answer:
m = v + 2
Step-by-step explanation:
Since Mags (m) is 2 years older than Vector (v)
You can use the equation V + 2 which is Vector's age + 2 years. Which would be equal to Mags' age.

60% of what number is 150?
Answers
Answer:
90
Step-by-step explanation:
To solve this you must make a proportion of x/150 60/100. Then you need to find the relation between 100 and 150 which is x 1.5. Then apply the same thing to 60 which results in 90.
Answer: 250
You must set this up as a proportion
Remember the percent is always over 100
150/x=60/100
Then solve the proportion
60x=15000
Get the x by its self
15000/60 is 250
x=250

Each homeroom must send two student representatives to each student council meeting. Mrs. Lincoln has 15 girls and 10 boys in her homeroom. If she randomly selects two students to attend the next meeting, find the probability of her choosing one girl and one boy?
Answers
Answer:
1/4
Step-by-step explanation:
Mrs. Lincoln has 15 girls and 10 boys in her homeroom. She randomly selects two students. The total number of students is 25.
The probability of choosing one girl is:
15 / 25 = 3 / 5
Now, 24 students are left.
The probability of choosing one boy is:
10 / 24 = 5 / 12
Therefore, the probability of choosing one girl and one boy is:
3 / 5 * 5 / 12
= 3 / 12
= 1/4

What is 2+12x?
Answers

Step-by-step explanation:
If 8x = 4, then you can solve for x by dividing both sides by 8. Therefore, x = 4/8 or 1/2.
Then to solve 2 + 12x you simply plug in 1/2 for x.
2 + 12x
2 + 12(1/2)
2 + 6
