The conditional relative frequency for female students who prefer playing sports is 34%.

<h3>How to determine the statistic calculated?</h3>

The table of values is given as:

Sports Dancing Row totals

Male students 18 16 34

Female students 18 35 53

Column totals 36 51 87

Mason's calculation is given as:

P = 21%

This is gotten by

18/87 = 21%

The above represents the joint relative frequency of female students who prefer playing sports.

To calculate the conditional relative frequency, he should divide 18 by the row total.

So, we have

18/53 = 34%

Hence, the conditional relative frequency for female students who prefer playing sports is 34%.

What is the solution to the inequality |2n+5| > 1 ?

Serhud [2]

Answer:

n > -2 or n < -3

Step-by-step explanation:

|2n+5| > 1

We have two solutions one positive and one negative. Remember to flip the inequality symbol for the negative

2n+5 > 1 or 2n+5 < -1

Subtract 5 from each side

2n+5-5 > 1-5 2n+5 -5 < -1 -5

2n >-4 2n < -6

Divide by 2

2n/2 > -4/2 2n/2 < -6/2

n > -2 or n < -3

A camera rental company charges a fixed amount plus a fee based on the number of days for which the camera is rented. The graph

Blababa [14]

(0,40)(4,120)
slope = (120 - 40) / (4 - 0) = 80/4 = 20

y = mx + b
slope(m) = 20
(0,40).....this means we have a y int of 40

so ur equation is : y = 20x + 40......this basically means the fee is $ 20 per day....and the fixed amount is $ 40 <===

Plz help me asnwer this

Daniel [21]

Answer:

x= 0

y= -3

Step-by-step explanation:

6x-5y=15

substitution...

6(y+3)-5y=15

6y+18-5y=15

y+18=15

-18 -18

y= -3

substitution again...

6x-5(-3)=15

6x+15=15

-15 -15

6x=0

/6 /6

x= 0
