What is the exact distance from (-5, 1) to (3,0)?

1 answer:

8 0

Distance is calculated by the square root of (x2-x1)^2 + (y2-y1)^2

We simply substitute the values into this formula

Square root of (3--5)^2 + (0-1)^2

Which is 8

Mr. Smith has an online cooking show. Before he films an episode about baking the perfect pound cake, he prepares his ingredient

Leviafan [203]

Answer:

Step-by-step explanation:

We are told in the question that:

Mr Smith's recipe calls for 2 1/2 cups of sugar for the cake and 1 1/4 cups of sugar for the vanilla glaze.

Step 1

We add up the total amount of sugar he would need

2 1/2 + 1 1/4

(2 + 1) + (1/2 + 1/4)

= 3 + (2 + 1/4)

= 3 3/4 cups of sugar.

Step 2

How many 1/4 cup scoops of sugar does he need?

This is calculated as:

3 3/4 cups of sugar ÷ 1/4

= 15/4 ÷ 1/4

= 15/4 × 4

= 15

Therefore, he would be needing 15 , 1/4 cup scoop of sugar

The question is incomplete. Here is the complete question.

A cell phone company is interested in the relationship between the number of texts per minute for their customers (y) and customer age. Based on the data collected, the least-squares regression line is $y=3.27+2.14x$ , where x is the number of years by which age exceeds 12. Which of the following statements best describes the meaning of the slope of the least-squares regression line?

a. For each increase in age of 1 year, the estimated number of texts per minute increases by 3.27.

b. For each increase in age of 1 year, the estimated number of texts per minute increases by 2.14.

c. For each increase of one text per minute, there is an estimated increase in age of 3.27 years.

d. For each increase of one text per minute, there is an estimated increase in age of 2.14 years.

e. The slope has no meaning because the units of measure for x and y are not the same.

Answer: b. For each increase in age of 1 year, the estimated number of texts per minute increases by 2.14.

Step-by-step explanation: The <u>least-squares</u> <u>regression</u> is a method of fitness, i.e., it fits a data set of number into an equation.

In this case, the relationship between number of texts per minute and customer age is given by a line equation:

$y=3.27+2.14x$

in which, y represents the number of texts per minute and x is the age.

In a line equation, slope is the measure of steepness, i.e., how inclined the line is.

In the least squares regression line, slope is 2.14 and it means, in each additional year, the number of texts increase by a factor of 2.14, which is the correct alternative.

6/7 of a number is 36. What is the number?

Over [174]

of a number = multiplication

Let us take the number as ' A '

6/7 × A = 36

A = 36 / 6/7

A = 36 × 7/6

A = 6×7

A= 42

The required answer is 42

Hope helps!

Find the difference. (7x-6 2/3) - (-3x + 4 3/4)

NikAS [45]

10x-61/12 is the difference of (7x- $6\frac{2}{3}$ ) - (-3x + $4\frac{3}{4}$ ).

<h3>What is Expression?</h3>

An expression is combination of variables, numbers and operators.

The given expression is (7x- $6\frac{2}{3}$ ) - (-3x + $4\frac{3}{4}$ )

7x- $6\frac{2}{3}$ +3x- $4\frac{3}{4}$

7x-20/3+3x-19/4

Add the variable terms and constant terms.

10x-20/3-19/4

The LCM of 3 and 4 is 12/

10x-4-57/12

10x-61/12

Hence, 10x-61/12 is the difference of (7x- $6\frac{2}{3}$ ) - (-3x + $4\frac{3}{4}$ ).
