Answer:

The needed equation relating P to N is P = $2300 + 90 N

His total pay if he sells 21 copies of Math is Fun is 4,190.

Step-by-step explanation:

The base salary of Juan = $2300

The earning on per copy sold = $ 90

P : His Total Pay

N : Number of books copies he sells.

Noe, here his earnings per copy sold = $90

So, the total earnings after selling N copies = N ( earning after 1 copy)

= N ( $90) = 90 N

TOTAL EARNINGS = BASE SALARY + MONEY EARNED after selling N copies

or, P = $2300 + 90 N

So, the needed equation relating P to N is P = $2300 + 90 N

Now, in second case: N = 21

So, P = 2300 + 90 N = 2300 + 90 (21)

= 2300 + 1890= 4,190

or, P = 4,190

Hence, his total pay if he sells 21 copies of Math is Fun is 4,190.

A crew of highway workers paved 1/2 mile in 1/4 hour. If they work at the same rate, how much will they pave in one hour?

mote1985 [20]

Step-by-step explanation:

The easiest approach is to realise that one hour is 3 times longer than

minutes. The longer the time, the more they will pave.

of a mile, in 20 minutes, how much in 60 minutes?#

They will pave 3 times more.

of a mile

You could also use the 'unitary method' where you find out how much they pave in ONE minute (divide by

) and them multiply by

to find how much in one hour.

135° Solve for <2. 62 = [?] 45° &2 86° Enter

andrey2020 [161]

Answer:

$\displaystyle \angle2 = {49}^{ \circ}$

Step-by-step explanation:

remember that,

if a side of a triangle is extended then exterior angle so formed equal to the sum of the two opposite interior angles

thus our equation is

$\displaystyle \angle2 + {86}^{ \circ} = {135}^{ \circ}$

cancel out 86° from both sides:

$\displaystyle \angle2 = {49}^{ \circ}$

hence,

the measure of the missing angle is 49°

Find the mean, the median, and all modes for the data in the given frequency distribution. (Round your answers to one decimal pl

kvasek [131]

Answer: Mean = 7.8

Median = 9

Mode = 2,9

Step-by-step explanation: Mean is the average value of a data set. Mean from a frequency table is calculated as:

$E(X)=\frac{2(10)+3(9)+9(10)+11(7)+12(3)+15(4)+16(3)}{10+9+10+7+3+4+3}$

E(X) = 7.8

Mean for the given frequency distribtuion is 7.8.

Median is the central term of a set of numbers. Median in a frequency table is calculated as:

1) Find total number, n:

n = 10 + 9 + 10 + 7 + 3 + 4 + 3 = 46

2) Find position, using: $\frac{n+1}{2}$

$\frac{n+1}{2}=\frac{47}{2}$ = 23.5

Median is in the 23.5th position.

3) Find the position by adding frequencies: for this frequency distribution, 23.5th position is 9

Median for this frequency distribution is 9.

Mode is the number or value associated with the highest frequency.

In this frequency distribution, 2 and 9 points happen 10 times. So, mode is 2 and 9.

Mode for this distribution is 2 and 9.

There are 12 people in cafe. half of them are drinking coffee. How many people are drinking coffee?

enot [183]

The answer is 6 people.

Half of the 12 people in the cafe would be 6 people. You can find half of a number by dividing it by two, or multiplying it by .5
