Tom [10]

Number of high school students which should the store expect next week, Mary predicts that the store will see 4,238 customers next week is 2392.

<h3>What is expected value?</h3>

The expected value is the long term average of the data or the mean of the data.

In order to better decide how to market a new line of clothing, Mary is researching the demographics of the customers of a certain clothing store.

She counted the number of customers who visited the store over the course of a month, and found out how many of the customers were high school students.

Her collected data is in the table below.

Week 1 2 3 4
Customers 2,848 3,141 3,861 3,911
Students 2,033 1,937 2,076 1,721

Mary predicts that the store will see 4,238 customers next week.

From using the long term mean value calculator for the provided data, the predicted value of the next week we get as 2392.

Hence, the number of high school students which should the store expect next week, Mary predicts that the store will see 4,238 customers next week is 2392.

Simplify expression 2g +3(g+5)

Sophie [7]

Answer:

$5g+15$

Step-by-step explanation:

To solve this question, we will first expand the expression using the distributive rule: $x(y+z)=xy+xz$

Therefore:

$2g+3(g+5)=2g+3*g+3*5$

Simplify:

$2g+3g+15$

Add up like terms:

$5g+15$

The vertices of ghk above have coordinates g(-3,4), h (1.-3), and k(2,7). the equation of the altitude to hk is

dalvyx [7]

We know that
the equation of the altitude to hk passes through point g and is perpendicular to segment hk

step 1
find the slope segment hk
<span>h (1.-3) k(2,7)
slope m=(y2-y1)/(x2-x1)----> m=(7+3)/(2-1)----> m=10

if two lines are perpendicular
so
m1*m2=-1

the altitude to hk has a slope
m2=-1/10

step 2
with m=-1/10 and point </span><span>g(-3,4) find the equation of the line
y-y1=m*(x-x1)-----> y-4=(-1/10)*(x+3)---> multiply by 10
10y-40=-x-3----> 10y+x=37-----> equation of the altitude

the answer is
</span>10y+x=37
<span>
see the attached figure
