Write the sum of the numbers as the product of their gcf and another sum Problem: 30+54

omeli [17]

The correct answer here is that the sum has to be 84. This is due to the fact that 30 + 54 is 84, and the greatest common factor is 6 because the factors of 30 are 1, 2, 3, 5, 6 , 10, 15, and 54's Factors: 1, 2, 3, 6, 9, 18, 27, and 54, so from this we can see that 6 is the great common factor.

A study of 40 white mice

zmey [24]

Answer:

$3.20-1.304\frac{0.8}{\sqrt{40}}=3.035$

$3.20+1.304\frac{0.8}{\sqrt{40}}=3.365$

And the confidence interval would be between (3.035;3.365)

Step-by-step explanation:

Information given

$\bar X=3.20$ represent the sample mean

$\mu$ population mean (variable of interest)

s=0.8 represent the sample standard deviation

n=40 represent the sample size

Confidence interval

The confidence interval for the mean is given by the following formula:

$\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}$ (1)

The degrees of freedom are given by:

$df=n-1=40-1=39$

The Confidence level is 0.80 or 80%, the significance would be $\alpha=0.2$ and $\alpha/2 =0.1$ , and the critical value would be $t_{\alpha/2}=1.304$
