Answer:

The college student can spend <u>$15.00</u> in December.

Step-by-step explanation:

This can be calculated as follows:

Let y represents the amount to spend in December.

The can now us the formula for calculating a mean is as follows:

Mean = Sum of montlhy spending / Number of months ...... (1)

From the question, we have:

Mean = $50

Sum of monthly spending = $100 + $25 + $80 + $30 + y = $235 + y

Number of months = 5

Substituting the values into equation (1) and solve for y, we have:

$50 = ($235 + y) / 5

$50 * 5 = $235 + y

$250 = $235 + y

$250 - $235 = y

$15.00 = y

Therefore, the college student can spend <u>$15.00</u> in December.

Find the value of w and YZ if Y is between X and Z. <br>XY = 4w YZ = 6W XZ = 12w - 8​
yulyashka [42]

Answer:

w = 4

YZ = 24

Step-by-step explanation:

Since, Y is a point lying between the points X and Z.

Therefore, relationship between the lengths of the segments will be,

length of segment XZ = length of XY + length of YZ

It's given in the question,

XZ = 12w - 8

YZ = 6w

XY = 4w

By substituting these values in the relation,

12w - 8 = 4w + 6w

12w - 8 = 10w

12w = 10w + 8

12w - 10w = 8

2w = 8

w = 4

Since, YZ = 6w

Therefore, YZ = 24

The population of a town can be modeled by the regression equation y = 20,000(1.03x). Which is the best prediction for the popul
bixtya [17]

Answer:

The best prediction for the population in year 25 is 41,876\ people

Step-by-step explanation:

we have a exponential function of the form

y=a(b^{x})

where

a is the initial value

b is the base

In this problem

a=20,000\ people

b=1.03

b=1+r

r=b-1=1.03-1=0.03

r=3\%

so

y=20,000(1.03^{x})

For x=25\ years

substitute

y=20,000(1.03^{25})

y=41,875.56\ people

Round up

y=41,876\ people

maria and her sister each have a salad and a drink for lunch at a restaurant. a salad costs $4.75 and a drink costs $1.65. what
oksano4ka [1.4K]
The salads in total are $9.50
The waters in total are $3.30

together the total cost is $12.80

First, convert the 15% to an actual number that can be used in a calculation. For percents, this is always done by simply dividing the percent (in this case 15%) by 100%. So, the conversational term "15%" becomes 15% / 100% = 0.15 in terms of a real mathematical number.

Second, you need to find out what 15% of your $12.80 meal cost is. This is always done by multiplying 0.15 by $12.80, or

0.15 x $12.80=$1.92.

So, the amount of tip you are going to leave is $1.92.

This makes the total cost of your meal (to write on your charge slip or other payment)

<span>$12.80 + $1.92 = $14.72.</span>
