Answer:

B = 5 and F = 5

Step-by-step explanation:

Step 1: B = 5 because 350(5) = 1750

Step 2: F = 5 because 525(5) = 2625

Step 3: 2625 +  1750 = 4375

Answer:

99% CI:

-4.637\leq\mu_v-\mu_o\leq 3.737

Step-by-step explanation:

We have to calculate a 99%CI for the difference of means for the vegan and the omnivore.

First, we have to estimate the standard deviation

s_{Md}=\sqrt{\frac{2MSE}{n_h}}

The MSE can be calculated as

MSE=\frac{(SSE_1+SSE_2)}{df} =\frac{(n_1s_1)^2+(n_2*s_2)^2}{n_1+n_2-2}\\\\MSE=\frac{(85*1.05)^2+(96*1.20)^2}{85+96-2}=\frac{7965.56+13272.04}{179} =118.65

The weighted sample size nh can be calculated as

n_h=\frac{2}{1/n_1+1/n_2}=\frac{2}{1/85+1/96}=\frac{2}{0.0222} =90.16

The standard deviation then becomes

s_{Md}=\sqrt{\frac{2MSE}{n_h}}=\sqrt{\frac{2*118.65}{90.16}}=\sqrt{2.632} =1.623

The z-value for a 99% confidence interval is z=2.58.

The difference between means is

\Delta M=M_v-M_o=5.10-5.55=-0.45

Then the confidence interval can be constructed as

\Delta M-z*s_{Md}\leq\mu_v-\mu_o\leq \Delta M+z*s_{Md}\\\\ -0.45-2.58*1.623\leq\mu_v-\mu_o\leq -0.450+2.58*1.623\\\\-0.450-4.187\leq\mu_v-\mu_o\leq-0.450+4.187\\\\-4.637\leq\mu_v-\mu_o\leq 3.737

The altitude is the mean proportional between the left and right parts of the hyptenuse

\cfrac{FI}{GI} =  \cfrac{GI}{HI} \ \ \Rightarrow \ \  \cfrac{FI}{15} =  \cfrac{15}{16} \ \ \Rightarrow \ \ FI= \cfrac{15 \cdot 15 }{16} \approx  14.1

Answer:

d = 11.401754

For:
(X1, Y1) = (5, 4)
(X2, Y2) = (-4, -3)


Distance Equation Solution:

=√ (-4−5)2+(−3−4)2

=√ (-9)2+(−7)2

=√ 81+49

=√ 130

=11.401754

Do i need to reverse the inequality symbol when i add the same positive number to or subtract the same positive number from both
stira [4]
No, You only reverse the inequality symbol when you divide by a negative number.
