Maria has the following scores on exams in her social studies class: 86, 75, 97, 58, 94, and 58.

A. Find the mean, median, and mode of the scores.

B. Should Maria’s social studies teacher use the mean, median, or mode of the exam scores to convince Maria that she needs to study more regularly for her exams?

Answers

Answer 1

Answer:

Below in bold.

Step-by-step explanation:

Arrange the scores in ascending order:

58 58 75 86 94 97

A. The mean = (58+58 +75+ 86+ 94+ 97)/6

= 468/6

= 78.

The median = (75+ 86)/2 = 80.5.

The mode = 58.

B. She should use the mode as it is the lowest score.

Answer 2
Mean: 78

Explanation: the mean is the average number in a data set, meaning you have to add all of the numbers and divide by the number of values (86 + 75 + 97 + 58 + 94 + 58) / 6

Median: 80.5

Explanation: The median is the value that separates the higher half from the lower half in a data set. in this case, you have to order the numbers least to greatest and since there is an even amount of numbers, you take the two middle ones and find the average of the two. (75 + 86) / 2

Mode: 58

Explanation: the mode is the value that appears most frequently in a data set, in this case it is 58

Part B: Maria’s social studies teacher should use the mode of the exam scores to convince Maria that she needs to study my regularly for her exams because it is the lowest score

Find a formula for the nth term of the sequence that begins 14.5, 16, 17.5, 19, 20.5 …. Assume that the first term corresponds to n=1.

F An=14.5+1.5(n-1)
G An=1.5+14.5(n-1)
H An=1.5+14.5n
J An=14.5+1.5n

Answers

Answer: F

Step-by-step explanation:

You can figure this out by plugging in the values of n for each expression and seeing which one gives you the given sequence.

Starting off with F
A(n) = 14.5 + 1.5(n-1)

A(1) = 14.5 + 1.5(1-1) --> 14.5 + 1.5(0) = 14.5

A(2) = 14.5 + 1.5(2-1) --> 14.5 + 1.5(1) = 16

A(3) = 14.5 + 1.5(3-1) --> 14.5 + 1.5(2) = 17.5

You can put in the remaining values of n if you want, but you should be able to notice that A(n) increases by 1.5 each term which follows the given sequence.

while J looks similar, it starts its sequence at 16 instead of 14.5 as it doesnt subtract 1 from n.

Carolyn is making a quilt using quilt blocks like the one shown below. All the shaded squares are the same size and all the shaded triangles are the same size. what is the ratio of the area of the shaded pieces to the area of the white pieces?

Answers

Answer:

117

Step-by-step explanation:

Side of shaded square = 3 in

Area of shaded square = side * side = 3 * 3 = 9 square inches

5 shaded square so we multiply the area by 5

Total area of shaded square = 9 * 5 = 45 square inches

Next the area of shaded triangle

Base of shaded triangle = 6 in

Height of shaded triangle = 6 in

Area of shaded triangle = 1/2 x base x height = 1/2 x 6 x 6 = 18

4 shaded triangles so we multiply the area by 4

Total area of shaded triangle = 18 * 4= 72 square inches

Area of shaded triangle + area of shaded square

Total area = 45 + 72 = 117 square inches

Answers

Answer:

the length of the missing side is 2

Step-by-step explanation:

Use a^2 + b^2 = c^2

a = 4

b = ?

c = 2sqrt5

4^2 + b^2 = (2sqrt5)^2

16 + b^2 = 20

subtract 16 from both sides

b^2 = 4

take the sqrt of both sides

b = 2

The table shows the cost for renting a canoe, based on the number of hours of rental. The pairs of values in the rows of the table form a linear function.
CANOE RENTAL
Hours Cost in Dollars
1 7

3 11
4 13
5 15
What is the meaning of the rate of change for the function?
A The price per hour for the rental is $2.
B The price per hour for the rental is $7.
C The base charge is $2.
D The base charge is $5.

Answers

Answer:

1) the rate of change is the change of the equation as it progress, in this case, it is the slope

Answers Below ↓

Step-by-step explanation:

a) Assuming the table giving is the original, this means that the slope here should be 2x, therefore, we would have to multiply all the numbers by 2

this gives:

(2, 14) (4, 18) (6, 22) (8, 26) and (10, 30)

b) like above this time, we would need to multiply the original by 7

this gives:

(7, 49) (14, 63) (21, 77) (28, 91) (35, 105)

c) base charge should be the charge they need to pay to rent the canoe, to add this in, we add 2 to the cost per hour

this gives:

(1, 9) (2, 11) (3, 13) (4, 15) (5, 17)

d) we do the same here:

(1, 12) (2, 14) (3, 16) (4, 18) (5, 20)

D the base charge is $5

How much paper do you need to wrap the box?

Answers

Answer:

2826  inches^2

Step-by-step explanation:

The general formula for the total surface area of a regular pyramid is

T.S.A.=12pl+B

Where p represents the perimeter of the base, l the slant height and B the area of the base.

The perimeter of the base is.  

p=2L+2W

P=2*10+2*9

P=20+18

P= 38  inches

The area of the base is.

B=10*9

B=90in^2

T.S.A.=12(38)(6)+90              

T.S.A=2736+90

T.S.A=2826  inches^2
