Answer:

1 and 13

Step-by-step explanation:

13 is a prime number.

By definition, a prime number is a whole number that can only be divided by itself and by 1 in order to result in a whole number

Estimate the solution to the system of equations.
Lynna [10]

Solving the system of equations we get x=\frac{5}{3} and y=\frac{14}{3}

Step-by-step explanation:

We need to find the solution to the system of equations.

y= 4x-2\\y = x+ 3

Solving the given equations and finding the values of x and y

Let:

y= 4x-2\,\,\,eq(1)\\y = x+ 3\,\,\,eq(2)

Putting value of y from eq(2) into eq(1)

4x-2=x+3\\4x-x=3+2\\3x=5\\x=\frac{5}{3}

So, value of x is: x=\frac{5}{3}

Putting value of x in eq(2) to find value of y

y=x+3\\y=\frac{5}{3}+3\\y=\frac{5+3*3}{3}\\y=\frac{5+9}{3}\\y=\frac{14}{3}

So, value of y is: y=\frac{14}{3}

So, solving the system of equations we get x=\frac{5}{3} and y=\frac{14}{3}

Dvinal [7]

Answer:

b. Do not reject H0. We do not have convincing evidence that the mean weekly time spent using the Internet by Canadians is greater than 12.7 hours.

Step-by-step explanation:

Given that in a study of computer use, 1000 randomly selected Canadian Internet users were asked how much time they spend using the Internet in a typical week. The mean of the sample observations was 12.9 hours.

H_0: \bar x =12.7\\H_a: \bar x >12,7

(Right tailed test at 5% level)

Mean difference = 0.2

Std error = \frac{6}{\sqrt{1000} } \\=0.1897

Z statistic = 1.0540

p value = 0.145941

since p >alpha we do not reject H0.

b. Do not reject H0. We do not have convincing evidence that the mean weekly time spent using the Internet by Canadians is greater than 12.7 hours.
