7 0

Answer: 320 boys

Step-by-step explanation: you would first take the total number (720) and divide it by the total number shown in the ratio (5+4=9)

720/9= 80

You would then take 80 and multiply it by 4 because that is the number representing the boys

80*4= 320

Nutka1998 [239]

Answer: 1.303639

Step-by-step explanation:

The t-score for a level of confidence $(1-\alpha)$ is given by :_

$t_{(df,\alpha/2)}$ , where df is the degree of freedom and $\alpha$ is the significance level.

Given : Level of significance : $1-\alpha:0.80$

Then , significance level : $\alpha: 1-0.80=0.20$

Sample size : $n=40$

Then , the degree of freedom for t-distribution: $df=n-1=40-1=39$

Using the normal t-distribution table, we have

$t_{(df,\alpha/2)}=t_{39,0.10}=1.303639$

Thus, the t-score should be used to find the 80% confidence interval for the population mean =1.303639

Multiply (3c+2p)(3c-2p) what is the answer?

Len [333]

9514 1404 393

Answer:

9c² -4p²

Step-by-step explanation:

The product of a sum and difference of the same two terms is the difference of their squares:

(3c +2p)(3c -2p) = 3c(3c -2p) +2p(3c -2p)

= (3c)² -6cp +6cp -(2p)²

= (3c)² -(2p)² = 9c² -4p²
