2 is a factor of 8 and 4 however it is not a multiple of either so the answer is 2

The factors of 8 are 1, 2, 4, and 8.
The first few multiples of 4 are 4, 8, 12, 16, and 20.

The factors of 8 that are multiples of 4 are 4, and 8.
Therefore, the factors of 8 that are not multiples of 4 are 1 and 2.

Hope this helps! :)

Answer:

4 shelves

Step-by-step explanation:

First you will have to subtract the one she keeps by her bed.

27 - 1 = 26 to be put on a shelf.

To find the least number of shelves needed, you will divided the total left by eight:

26 ÷ 8 = 3.25

She can fill 3 shelves completely and still have books left over. So she needs at least 4 shelves!

Love your profile pic btw! :)

5 0 = - in = in quadrant II Given cos = Find sin 3

____ [38]

Answer:

sinΘ = $\frac{2}{3}$

Step-by-step explanation:

using the identity

sin²x + cos²x = 1 ( subtract cos²x from both sides )

sin²x = 1 - cos²x ( take square root of both sides )

sinx = ± $\sqrt{1-cos^2x}$

given

cosΘ = - $\frac{\sqrt{5} }{3}$ , then

sinΘ = ± $\sqrt{1-(-\frac{\sqrt{5} }{3})^2 }$

= ± $\sqrt{1-\frac{5}{9} }$

= ± $\sqrt{\frac{4}{9} }$

= ± $\frac{2}{3}$

since Θ is in quadrant II where sinΘ > 0 , then

sinΘ = $\frac{2}{3}$

A teacher was interested in finding out whether a special study program would increase the scores of students on a national exam

bija089 [108]

Answer:

Check the explanation

Step-by-step explanation:

Going by the first attached image below we reject H_o against H_1 if obs. $T > t_{\alpha /2;n-1}$

here obs.T=1.879

$\therefore obs.T \ngtr 2.447=t_{0.025;6}$

we accept $H_o:\mu _{1}=\mu_{2}$ at 5% level of significance.

i.e there is no sufficient evidence to indicate that the special study program is more effective at 5% level of significance.

this problem is simillar to the previous one except the alternative hypothesis.

Let X_i's denote the bonuses given by female managers and Y_i's denote the bonuses given by male managers.

we assume that $X_i \sim N(\mu _{1},\sigma _{1}^{2}) Y_i \sim N(\mu _{2},\sigma _{2}^{2})$ independently

We want to test $H_0:\mu_{1}=\mu_{2} vs H_1:\mu_{1}\neq \mu_{2}$

define $D_i=X_i-Y_i , i=1(1)8$

now $D_i\sim N(\mu _{1}-\mu _{2}=\mu _{D},\sigma _{1}^{2}+\sigma _{2}^{2}=\sigma _{D}^{2}) , i=1(1)8$

the hypothesis becomes

$H_0:\mu_{D}=0 vs H_1:\mu_{D}\neq 0$

in the third attached image, we use the same test statistic as before

i.e at 5% level of significance there is not enough evidence to indicate a difference in average bonuses .

Find the volume of a pyramid with a square base, where the area of the base is

never [62]

Answer:

$V=60.28\ cm^3$

Step-by-step explanation:

Given that,

The area of the base = 13.2 cm²

The height of the pyramid = 13.7 cm

We need to find the volume of this pyramid. The formula can be given by :

$V=\dfrac{1}{3}Bh$

Put all the values,

$V=\dfrac{1}{3}\times 13.2\times 13.7\\\\V=60.28\ cm^3$

So, the volume of the pyramid is equal to $60.28\ cm^3$ .
