Suppose a local pizzeria delivers pizzas every day of the week and their delivery times are normally distributed with a mean of 30 minutes with a standard deviation of 4 minutes. Determine the interval that contains the middle 80% of delivery times.

Answers

Answer 1

Answer:

interval in minutes = (24.88, 35.12)

Step-by-step explanation:

we can use the following formula:

interval = population mean ± (z · σ)

population mean = 30 minutesz for 80% = 1.28σ = 4 minutes

interval = 30 minutes ± (1.28 · 4 minutes)

interval in minutes = (30 - 5.12), (30 + 5.12) = (24.88, 35.12)

36

using a calculator that can perform only the four basic operations. How do you respond?

Answers

Answer:

16.4722222222

Step-by-step explanation:

The quotient and remainder should be 16 and 17 respectively.

Given that,

The problem is 593 ÷ 36.By using the calculator we can perform the four operations i.e. addition, subtraction, multiplication & division.

The division result in the division operator is

593 ÷ 36  = 16.4722So, the quotient is 16.

Now the remainder should be

(16.4722 - 16) ×36 = 17

Therefore we can conclude that the quotient and remainder should be 16 and 17 respectively.

Which two answer choices below would give you a value of 3 times larger than (820 + 220)?

A) 3(820 + 220)
B) 3(820) + 2(220)
C) 2460 + 660
D) 820 x 220 x 3

Answers

A and d, because 820+220 is equal to 1,040, multiplied by 3 is 3120 and both a and d equal this

The expression that gives you a value of 3 times larger than (820 + 220) are:

3(820 + 220)

2460 + 660

Options A and C are the correct answer.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

(820 + 220)

= 1040

Now,

3 x 1040

= 3120

Now,

A)

3(820 + 220)

= 3 x 1040

= 3120

B)

3(820) + 2(220)

= 2460 + 440

= 2900

C)

2460 + 660

= 3120

D)

820 x 220 x 3

= 541200

Thus,

3(820 + 220) and 2460 + 660 give the value of 3 times larger than

(820 + 220).

Answer: B

Step-by-step explanation:

To find the result of the dilation, multiply each x and y coordinate by the scale factor, which in this case, is 1.5. I started out with the coordinate P, which had an original coordinate of (-2,1). In this case, I multiplied -2 by 1.5, and 1 by 1.5 to get (-3, 1.5). Since this is multiple choice, the only one with P as (-3, 1.5) is B, so we don't have to check the others.

The answer is B.

Which equation shows the point-slope form of the line that passes through (3, 2) and has a slope of 1/3?

Answers

Answer:

Option 2: [tex]y - 2 = \frac{1}{3}(x-3)[/tex] is the correct answer.

Step-by-step explanation:

The equation of a line with given point(x1,y1) and slope m is given by:

[tex]y-y_1 = m(x-x_1)[/tex]

The line passes through (x1,y1)

Given

[tex](x_1,y_1) = (3,2)\\m = \frac{1}{3}[/tex]

=> x1 = 3

=> y1 = 2

Putting the values of x1, y1 and slope(m) in the point-slope form, the equation of line is:

[tex]y - 2 = \frac{1}{3}(x-3)[/tex]

Hence,

Option 2: [tex]y - 2 = \frac{1}{3}(x-3)[/tex] is the correct answer.

Slope of (3, -9) (3, 18)

Once we substitute in the provided points, this becomes [tex]\frac{18-(-9)}{3-3}[/tex].

Simplify to [tex]\frac{27}{0}[/tex].

This does not give us a number and instead results in an undefined slope, aka a vertical line.

Which of the following ratios is closest to the golden ratio? a. 5/3

d. 14/11

Answers

Answer:

A 5/3

Step-by-step explanation:

The fraction closest to the golden ratio is  a. 5/3.

What is a golden ratio?

The golden ratio is a ratio between two numbers that approximate 1.618.

It is sometimes referred to as the golden number, the golden proportion, or the divine proportion.

It is closely related to the Fibonacci sequence, a set of numbers where each number is added to the previous one and is typically written as the Greek letter Ф.

From the given options,

5/3 = 1.66.

7/5 = 1.4.
