Let the numbers be n, n+2, n+4

Sum equals too= 13+2(n+4), which is 2n+21

a) Equation--> n+n+2+n+4= 2n+21

b) Solution--> 3n+6= 2n+21

=> n= 15

c) Second number--> 17 (15+2)

Third number--> 19 (15+4)

d) 15+15+2+15+4=30+21

=> 51= 51

So, the equation is true.

snow_lady [41]

Answer:

The z score for a wide receiver who dropped 13 footballs over the course of a season

Z = - 1.5

Step-by-step explanation:

Explanation:-

Given Population mean ' μ'= 16

Standard deviation of Population 'σ' = 2

Let 'x' be the Random Variable of Normal distribution

Given x = 13 foot balls

The z score for a wide receiver who dropped 13 footballs over the course of a season

$Z = \frac{x-mean}{S.D}$

$Z = \frac{13 -16}{2} = \frac{-3}{2} = -1.5$

Final answer:-

The z score for a wide receiver who dropped 13 footballs over the course of a season

Z = - 1.5

2x+9>17 or 5x+10<10 compound inequalities

Natali [406]

Answer: 2x+9>17 or 5x+10<10 compound inequalities is x<0

Step-by-step explanation:

What is Meant by Compound Inequality?

In Mathematics, a compound inequality is a sentence which has two statements connected using the word “and” or by the word “or”. If the statements are connected using the word “and”, then both the statements of the compound sentence are true at the same time. If the statements are connected using “or”, then the compound sentence is true if at least one statement is true.

2x+9>17 or 5x+10<10

Let take 2x+9>17

Subtract -9 on both sides

2x+9-9>17-9

2x+0>8

2x>8

Now we need to divide by 2 both sides

2x÷2>8÷2

x>4

Now we solve 5x+10<10

we need to subtract -10 on both side

5x+10-10<10-10

5x+0<0

5x<0

Now we need to divide 5 on both sides

5x÷5<0÷5

x<0
