The perimeter of the polygon will be given by:
Perimeter=distance around the figure
Thus the perimeter will be:
P=9.9+(9.9-5.9)+5.9+15.9+(15.9-4.6)+4.6
P=9.9+4+5.9+15.9+11.3+4.6
P=51.6 
Answer: 51.6 units

Answer:

D. $7.88

Step-by-step explanation:

All you have to do is multiply the number of apples by the cost of each apple. Fractions won't change the equation.

Shown Work:

4 1/2 × $1.75 = $7.875 -- round to nearest 100ths place -- $7.88

Researchers randomly divided 500 volunteers into two equal-sized groups. One group spent 6 months on the Paleo diet. A control g
gtnhenbr [62]

Answer:

p_v =P(t_{(498)}>1.356)=0.088

And we can use the following excel code to find it: "=1-T.DIST(1.356,498,TRUE)"

Step-by-step explanation:

Data given and notation

\bar X_{P}=7 represent the mean for the sample Paleo

\bar X_{C}=5 represent the mean for the sample Control

s_{P}=20 represent the sample standard deviation for the sample Paleo

s_{C}=12 represent the sample standard deviation for the sample Control

n_{P}=250 sample size selected Paleo

n_{C}=250 sample size selected Control

\alpha represent the significance level for the hypothesis test.

t would represent the statistic (variable of interest)

p_v represent the p value for the test (variable of interest)

State the null and alternative hypotheses.

We need to conduct a hypothesis in order to check if the Paleo diet provides more weight control than the control treatment, the system of hypothesis would be:

Null hypothesis:\mu_{P}-\mu_{C}\leq 0

Alternative hypothesis:\mu_{P}-\mu_{C}>0

We don't know the population deviations, so for this case is better apply a t test to compare means, and the statistic is given by:

t=\frac{(\bar X_{P}-\bar X_{C})-12}{\sqrt{\frac{s^2_{P}}{n_{P}}+\frac{s^2_{C}}{n_{C}}}} (1)

t-test: "Is used to compare group means. Is one of the most common tests and is used to determine whether the means of two groups are equal to each other".

Calculate the statistic

We can replace in formula (1) the info given like this:

t=\frac{(7-5)-0}{\sqrt{\frac{20^2}{250}+\frac{12^2}{250}}}}=1.356  

P-value

The first step is calculate the degrees of freedom, on this case:

df=n_{P}+n_{C}-2=250+250-2=498

Since is a one side right test the p value would be:

p_v =P(t_{(498)}>1.356)=0.088

And we can use the following excel code to find it: "=1-T.DIST(1.356,498,TRUE)"

Six friends share 3 oatmeal squares equally. How much of an oatmeal square does each friend get?
Kobotan [32]
If there are 3 oatmeal squares, and 6 people share them then you have to do 3÷6= 0.5, 1/2 or 1 half of each. Each person gets 1 half of an oatmeal square.
Hope it helps!!! :)

If 50 percent of x=66 then x =
sasho [114]

Answer:

132

Step-by-step explanation:

50 % means half

so 66 is half of whatever x is.

to find x you have to multiply 66 by 2 or add 66 to 66 which will give you 132 either way.

<em>Hope this helps you! have an amazing day :)</em>
