Answer:

small triangle area = 1/2(8)(14) = 56 m²

bigger triangle area = 1/2(16)(14) = 112 m²

biggest triangle area = 1/2(24)(14) = 168 m²

there's 2 bigger triangles so you pick the bigger one you want

Answer:

smaller triangle area = 56m²

larger triangle area = 112m²

total area = 168m²

Step-by-step explanation:

Area of triangle = \frac{bh}{2}

where b = base length and h = height

smaller triangle dimensions

base length= 8m

height = 14m

* plug in the values into the formula *

area=\frac{8*14}{2} \\8*14 =112\\\frac{112}{2}=56\\A=56m^2

so we can conclude that the area of the smaller triangle is 56 square meters

larger triangle dimensions

base length = 16m

height = 14m

* plug in the values into the formula *

area=\frac{16*14}{2} \\16*14=224\\\frac{224}{2} =112\\A=112m^2

so we can conclude that the area of the larger triangle is 112 square meters

total area = the sum of the two triangle's area

total area = 112 + 56

112 + 56 = 168

hence the total area is 168 square meters

A researcher believes that the mean weight of competitive runners is about 140 pounds. A sample of 24 elite distance runners has
ExtremeBDS [4]

Answer:

t=\frac{136-140}{\frac{11}{\sqrt{24}}}=-1.781    

p_v =P(t_{(23)}  

If we compare the p value and the significance level assumed \alpha=0.05 we see that p_v so we can conclude that we have enough evidence to reject the null hypothesis, so we can conclude that the mean is less than 140 pounds at 5% of signficance.  

Step-by-step explanation:

Data given and notation  

\bar X=136 represent the sample mean

s=11 represent the sample standard deviation

n=24 sample size  

\mu_o =140 represent the value that we want to test

\alpha=0.01 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 mean is less than 140, the system of hypothesis would be:  

Null hypothesis:\mu \geq 140  

Alternative hypothesis:\mu < 140  

If we analyze the size for the sample is < 30 and we don't know the population deviation so is better apply a t test to compare the actual mean to the reference value, and the statistic is given by:  

t=\frac{\bar X-\mu_o}{\frac{s}{\sqrt{n}}}  (1)  

t-test: "Is used to compare group means. Is one of the most common tests and is used to determine if the mean is (higher, less or not equal) to an specified value".  

Calculate the statistic

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

t=\frac{136-140}{\frac{11}{\sqrt{24}}}=-1.781    

P-value

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

df=n-1=24-1=23  

Since is a one left tailed test the p value would be:  

p_v =P(t_{(23)}  

Conclusion  

If we compare the p value and the significance level assumed \alpha=0.05 we see that p_v so we can conclude that we have enough evidence to reject the null hypothesis, so we can conclude that the mean is less than 140 pounds at 5% of signficance.
