ankoles [38]3 years ago
7 0

Answer:

subtract the number you have from the number you're going to. For example, if you were trying to figure out the distance between 6 and 18, you would subtract 6 from 18 which is 12. I hope this answers your question!

Step-by-step explanation:

In a mid-size company, the distribution of the number of phone calls answered each day by each of the 12 receptionists is bell-s
Radda [10]

Answer:

68%

Step-by-step explanation:

The Standard Deviation Rule = Empirical rule formula states that:

68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ.

95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ.

99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ.

From the question,

Step 1

We have to find the number of Standard deviation from the mean. This is represented as x in the formula

μ = Mean = 61

σ = Standard Deviation = 8

For x = 53

μ - xσ

53 = 61 - 8x

8x = 61 - 53

8x = 8

x = 8/8

x = 1

For x = 69

μ + xσ

69 = 61 + 8x

8x = 69 - 61

8x = 8

x = 8/8

x = 1

This falls within 1 standard deviation of the mean where: 68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ.

Therefore, according to the Standard Deviation Rule, the approximate percentage of daily phone calls numbering between 53 and 69 is 68%

Hillside Elementary ordered 40 pizzas for
Whitepunk [10]

Answer:

28 pizzas eaten

Step-by-step explanation:

1) estimate each number, i will take 3 1/4 as 3

5 3/4 as 6

and

2 3/4 as 3

2) combine the total number of pizzas left over:

3+6+3=12

subtract the number of pizzas left over from the total ordered:

40-12=28

15% of what number is 9?
Sholpan [36]

Answer:

x=60

Step-by-step explanation:

We have, 15% × x = 9

or,  

15

100

× x = 9

Multiplying both sides by 100 and dividing both sides by 15,

we have x = 9 ×  

100

15

x = 60

If you are using a calculator, simply enter 9×100÷15, which will give you the answer.

Please help, it's due really soon!
kipiarov [429]

Answer:

Ok so you have to figure out what is the input, output, y-intercept (b), slope (m), and equation.

First, input is the x. Looking at the graph.

Input : 0, 10, 20

Second, output is the y. Looking at the graph.

Output : 20, 30, 40

Third, y-intercept is the b in the equation of y = mx + b. Looking at the graph.

Y-intercept (b) : 20

Fourth, slope is the m in the equation of y = mx + b. Looking at the graph.

Slope (m) : 1/2

Fifth, you have to find the equation in the form of y = mx + b. Looking at the graph.

Equation : y = 1/2x + 20

I hope this helps and if you have any other questions I would be glad to answer it, thank you :) !!

In the diagram below, quadrilateral ABCD is inscribed in a circle. What is the measure of angle D?
grin007 [14]

Given:

In the circle P, ABCD is inscribed quadrilateral.

And, ∠DAB = 110°, ∠ABC = 72°

To find the value of ∠ADC.

Theorem:

A quadrilateral can be inscribed in a circle if and only if the opposite angles are supplementary [ sum of the opposite angles will be 180°]

According to the theorem,

\angle ABC+\angle ADC = 180^{\circ}

     \angle ADC +72^{\circ} = 180^{\circ}

               \angle ADC = 180^{\circ}-72^{\circ}

               \angle ADC = 108^{\circ}

Hence,

The value of ∠ADC is 108°.

Hence, Option b is the correct answer.
