A teacher surveyed her class after they had taken a vocabulary test. Eighteen of the students claimed they had studied at least one hour for the test. The remaining twelve students admitted that they had not studied for the test at all. The test results (expressed as a percent) for the two groups are shown below.

Studied: 88, 100, 94, 79, 92, 100, 95, 83, 89, 99, 100, 91, 89, 95, 100, 93, 96, 84

Did Not Study: 82, 72, 45, 91, 58, 83, 65, 87, 90, 77, 73, 89

Calculate the range and interquartile range for each set of data.
Using complete sentences, compare the data sets based on your results in part A.

ANSWER TO QUESTION

Part A

Studied : 79, 83, 84, 88, 89, 89, 91, 92, 93, 94, 95, 95, 96, 99, 100, 100, 100, 100
Range : 21
Interquartile range : 99.5 - 89 = 10.5

Did not study : 45, 58, 65, 72, 73, 77, 82, 83, 87, 89, 90, 91
Range : 46
Interquartile range : 89 - 65 = 24

Part B

The students that claimed to study had a lower range and interquartile than the students that did not study. Range difference between the students that did not study vs the students that did study, 46 > 21. Interquartile range difference between the students that did not study vs the students that did, 24 > 10.5.

Answer:

781/10000

Step-by-step explanation:

These are independent events so we can multiply the probabilities

P(5 on the coin ) = 11/100

P( tail on the coin) = 71/100

P( 5 and tails) = 11/100 * 71/100

                      = 781/10000

Answer:

the probability of rolling a 5 on the number cube and the coin landing on tails is 781 over 10,000

Step-by-step explanation:

T= 71 times

11= 5 rolled

71/100 * 11/100 = 781/10000

Answer:

d = -1000

Answer:

d = −1,000

Step-by-step explanation:

d*88= −88,000

88d = −88,000

/88         /88

d = −1,000

The expressions that represent the area of the quadrilateral shown is first and last options.

Area of a two dimensional shape is the total region which is bounded by the object's shape.

Given is a quadrilateral.

This can be divided into known quadrilaterals to find the area.

This can be done in two ways as shown in the image below.

Area of rectangle/square = Length × Width

Area of triangle = [tex]\frac{1}{2}[/tex] × base × height

As shown in the first figure,

Area of the quadrilateral ADGH = Area of rectangle ABCD - Area of ΔABH - Area of ΔGHE - Area of square GECF - Area of ΔFGD.

Area = (8 × 8) - ([tex]\frac{1}{2}[/tex] × 8 × 2) - ([tex]\frac{1}{2}[/tex] × 2 × 4) - (2 × 2) - (([tex]\frac{1}{2}[/tex] × 6 × 2)

This is the first option.

As shown in the second figure,

Area of quadrilateral GFBE = Area of ΔGDF + Area of ΔBCF + Area of rectangle ABCD + Area of ΔABE

Area = ([tex]\frac{1}{2}[/tex] × 8 × 2) + ([tex]\frac{1}{2}[/tex] × 2 × 4) + (6 × 4) + ([tex]\frac{1}{2}[/tex] × 6 × 2)

This is the last option.

Hence the area of the quadrilateral can be either first or last option.

Answer:

x - 5 ≤ 0,  x  + 13 ≥ 0  

Step-by-step explanation:

All numbers such that x≤5.

x - 5 ≤ 0

All numbers such that x≥−1.3.

x  + 13 ≥ 0  

The absolute value equations in the form of  |x-b|= c(where b is a number and c can be either a number or an expression) that has the following solution set

all numbers such that x ≤ 5 and all numbers such that x ≥ -1.3 will be x -5 ≤ 0 and x + 1.3 ≥ 0.

Isolate the absolute number on one side of the equation to solve an equation containing the absolute value.

Then, resolve both equations by changing their respective contents to the positive and negative values of the variable on the other side of the equation.

In another word, the absolute value equation is the equation that has a real absolute value not imaginary and not binary.

In the mode function, it could be two values if the mode is going negative or positive.

Given that the equation |x-b| = c and constraint is

all numbers such that x ≤ 5

all numbers such that x ≥ -1.3

so by substituting we will get x -5 ≤ 0 and x + 1.3 ≥ 0.

Step-by-step explanation:

12% of 750 is 90

Answer:

15

Step-by-step explanation:

Equation to remember:

Length · Width · Height = Volume

LWH = V

-------------------------------------------------

In this word problem, you can find that we're missing the height aspect of the equation. Your equation would look something like this:

[tex]12 * 10 * h = 1800[/tex]

-------------------------------------------------

Work:

[tex]12 * 10 * h = 1800\\\\120h = 1800\\\\\frac{120h}{120} = \frac{1800}{120}\\\\h = 15[/tex]

Answer:

A'' (-1,5)

B'' (0,1)

C'' (-3,-1)

Step-by-step explanation:

For A,

Step 1, (2,2) change to (-2,2), cuz if reflect in y-axis, positive value of x will change to negative value of x, negative value of x will change to positive value of x.

Step 2, (-2,2) change to (-1,5), cuz we add up the 1 to x-value, add up 3 to y value.

For B,

Step 1,

(1,-2) to (-1,-2)

Step 2,

(-1,-2) to (0,1)

For C,

Step 1,

Answer:

w = 7, and w = 8 is correct

Step-by-step explanation:

1. Why 5 does not work

a. Substitute 5 into the equation

5w-10>20 --> 5(5) - 10 > 20

b. Solve the equation

Remember Pemdas:

P- Parentheses First

E- Exponents Second

M- Multiplication Third

D- Division Fourth

A- Addition Fifth

S- Subtraction Sixth

We are not working with Exponents and Parentheses, but we are working with the rest.

Since there is no P and E, that means that multiplication is first

5(5)-10>20 - 5(5) = 5 x 5 = 25

Now all is left is to subtract:

25 - 10 = 15

15 > 20 Is not true.

2. Why 6 does not work

a. Substitute

5w-10>20 --> 5(6) - 10 > 20

b. Solve

5(6) = 5 x 6 = 30

30 - 10= 20

20 > 20 is not true

Just like you are not greater than yourself, 20 can not be greater than its own self.

3. Why 7 and 8 work (7a, 7b is 7; 8a, 8b is 8)

7a. Substitute

5w-10>20 --> 5(7) - 10 > 20

8a. Substitute

5w - 10 >20 --> 5(8) - 10 > 20

7b. Multiply and subtract

5(7) = 5 x 7 = 35

35 - 10 = 25

25 > 20

25 is greater than 20

8b. Multiply

5(8) = 5 x 8 = 40

40 - 10 = 30

30 > 20

30 is greater than 20

Hereby, w = 7, and w = 8

Step-by-step explanation:

Answer:

the sentences that are true are..:

Two sides have the same length

The third angle measures 70°

It is an acute triangle.

i know that because eat triangle is 180°, so if we subtract 40° and 70° from 180°, we get 70°, meaning the three angles in the triangle are 40°, 70°, and 70°. Because all of the angles are under 90°, we know that it is an acute triangle.

The answers are (d) The third angle measures 90° and (e) All sides have different lengths.

Answer:

40% = 100%

15 = (100% - 15% = 85%) 85% in Alaska

California = 15% of 40 = (0.15 x 40) = 6

Alaska = 85% of 40 = (0.85 x 40) = 34

Answer:

30.99 inHg.

Step-by-step explanation:

First, subtract how much the pressure dropped on Tuesday from Monday's reading. 30.01 inHg - 0.34 inHg = 29.67 inHg

Then, add how much the pressure climbed on Wednesday to Tuesday's reading. 29.67 inHg + 1.32 inHg = 30.99 inHg

Answer:

The barometric pressure reading for Wednesday was 31.01inHg. This can be calculated by subtracting 0.34inHg from the pressure reading on Monday (30.01inHg) and then adding 1.32inHg, which results in 31.01inHg.
