Eli buys 8 gigabytes of memory for his computer he spends 392. whatbis the cost of 1 gigabyte memory

kotykmax [81]

If Eli spends $392 for 8 gigabytes of memory, then $8g=392$ , where g is a gigabyte of memory. All you have to do is to reduce the equation. In this case, divide both sides by 8 to get $g=49$ . So the cost of 1 gigabyte of memory is $49.

The length of a rectangle is 11 in. longer than its width. the perimeter of the rectangle is 86 in.write and solve an equation t

Tcecarenko [31]

I hope this helps you

width w

length w+11

perimeter =2 (width +length )

86=2 (w+w+11)

43=2w+11

32=2w

w=16

length = w+11=16+11=27

The average expenditure on Valentine's Day was expected to be $100.89 (USA Today, February 13, 2006). Do male and female consume

AfilCa [17]

Answer:

Yes. The male and female consumers differ in the amounts they spend.

Step-by-step explanation:

We can express the null and alternative hypothesis as:

$H_0: \mu_m=\mu_w\\\\H_1: \mu_m\neq\mu_w$

It is assumed a significance level of 0.05.

The standard deviation of the difference of means is calculated as:

$s=\sqrt{\frac{s_m^2}{n_m} +\frac{s_w^2}{n_w} } =\sqrt{\frac{35^2}{40} +\frac{20^2}{30} } =\sqrt{30.625+13.333} =\sqrt{43.958} =6.63$

The test statistic is

$t=\frac{(M_m-M_w)-0}{s}=\frac{135.67-68.64}{6.63}=10.11$

The degrees of freedom are:

$df=n_1+n_2-2=40+30-2=68$

The P-value for t=10.11 is P=0, so it is smaller than the significance level. The null hypothesis is rejected.

We can conclude that male and female consumers differ in the amounts they spend.
