ANSWER

$y = 5x + 6$

EXPLANATION

The equation of the given line is

$y=5x-7$

This line is in the slope -intercept form,

$y = mx + c$

where

$m = 5$

is the slope.

The line which is parallel to this line and passes through (1,11) also has slope

$m = 5$

Let the equation of this line be

$y = mx + b$

This implies

$y = 5x + b$

We substitute x=1 and y=11 to get

$11 = 5(1) + b$

$b = 11 - 5 = 6$

The required equation is

$y = 5x + 6$

Given the two sets, what is A ∩ B ? A = {1, 2, 3, 4, 5, 6} B = {2, 3, 5, 7}

topjm [15]

Answer:

2, 3, 5

Step-by-step explanation:

A∩B means "A intersection B" which includes all elements that are shared in BOTH sets. This would be the middle crossover section of a Venn diagram.

Hence, 2 and 3 and 5 are shared in both sets.

The marketing club at school is opening a student store. They randomly survey 50 students about how much money they spend on lun

Luden [163]

Answer:

The expected value for a student to spend on lunch each day = $5.18

Step-by-step explanation:

Given the data:

Number of students______$ spent

2 students______________$10

1 student________________$8

12 students______________$6

23 students______________$5

8 students_______________$4

4 students_______________$3

Sample size, n = 50.

Let's first find the value on each amount spent with the formula:

$\frac{num. of students}{sample size} * dollar spent$

Therefore,

For $10:

$\frac{2}{50} * 10 = 0.4$

For $8:

$\frac{1}{50} * 8 = 0.16$ l

For $6:

$\frac{12}{50} * 6 = 1.44$

For $5:

$\frac{23}{50} * 5 = 2.3$

For $4:

$\frac{8}{50} * 4 = 0.64$

For $3:

$\frac{4}{50} * 3 = 0.24$

To find the expected value a student spends on lunch each day, let's add all the values together.

Expected value =

$0.4 + $0.16 + 1.44 +$2.3 + $0.64 + $0.24

= $5.18

Therefore, the expected value for a student to spend on lunch each day is $5.18
