Answer:

c.126 red

Step-by-step explanation:

red+green+yellow=350

10% out of 350 are yellow

0.1 times 350=35

350-35=315

3/5 out of 315 are green

red is not green so

2/5 of what is left is red

2/5 of 315 is red

2/5 times 315=430/5=126

126 red

NFL Pre-Season Teams in the National Football League (NFL) in the US play four pre-season games each year before the regular sea
Mazyrski [523]

Answer:

H0 : ρ = 0

H1 : ρ ≠ 0

Test statistic = 1.197

Pvalue = 0.2335

There is no correlation between the two variables

Step-by-step explanation:

The null and alternative hypothesis :

H0 : No correlation exist,

H1 : Correlation exist

H0 : ρ = 0

H1 : ρ ≠ 0

Test statistic, T = r / √(1 - r²) / (n - 2)

T = 0.067 / √(1 - 0.067²) / (320 - 2)

T = 0.067 / √(0.995511 / 318)

T = 0.067 / 0.0559512

T = 1.197

The Pvalue obtained from the Rscore, at df = 320 - 2 = 318 is 0.2335

α = 5% = 0.05

The Pvalue > α ; we fail to reject the null and conclude that, there is no correlation between the two variables.

5x^2+15=51; square root property
charle [14.2K]
1. Subtract 15 to the other side (5x^2 = 36)

2.Square root both sides to remove the squared of 5x^2 (sqrt(5x^2) = sqrt(36) simplified to 5x = 6)

3. divide by 5 to get x = 6/5

Final result is 6/5

lidiya [134]

Answer:

interchange the role of x and y

x=9y+5

x-5=9y

<u>x-5</u><u> </u>=y

9

so,f^-1(x)= <u>x-5</u>

<u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>9
