Can someone help me find the area of this figure with steps pls!!!
r-ruslan [8.4K]

separate the figure into easier parts first. for example two rectangles. first to find the area of the bottom rectangle multiply 10 * 4 = 40. the second rectangle has a height of 8 and a width of 5 because 3 + 2 = 5 and 10 - 5 will get you the width of the top rectangle. 8 * 5 = 40. now add both of the rectangles to get the final area which would be 40 + 40 = 80cm

F(x) = 2x + 1  when x <= -5
Now -10 is less than -5 so we plug x = -10 into 2x +1:-

f(-10) = 2(-10) + 1 =  -19 answer

Now f(x) = x^2 when  -5< x < 5
x =2  is within this range so f(2) = 2^2 = 4 answer

You can calculate the  other 3  values by a similar method

Anna11 [10]

Answer:  108 cubic inches

Step-by-step explanation:

Hi, to answer this question we have to apple the next formula:

Volume of a rectangular prism (V): base area x height  (deep of the soil)

Replacing with the values given:

V = 36 x 3 =108 cubic inches

Ian should put 108 cubic inches of soil in the flower pot.

The volume of the soil is 108 cubic inches.

Feel free to ask for more if needed or if you did not understand something.

The average high-density lipoprotein (HDL) cholesterol level of adult females is 53 milligrams per deciliter. You want to determ
emmasim [6.3K]

Answer:

t=\frac{54.1-53}{\frac{1.78}{\sqrt{12}}}=2.14  

df = n-1= 12-1=11

p_v = P(t_{11}>2.14) =0.0278

Step-by-step explanation:

Data provided

\bar X=54.1 represent the sample mean in mg per deciliter of cholesterol level

s=1.78 represent the sample standard deviation

n=12 sample size  

\mu_o =53 represent the value that we want to test  

t would represent the statistic (variable of interest)  

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

System of hypothesis

We need to conduct a hypothesis in order to check if the mean is higher than 53 mg per deciliter, the system of hypothesis would be:  

Null hypothesis:\mu \leq 53  

Alternative hypothesis:\mu > 53  

The statistic is given by:

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

Calculate the statistic  

Replacing into the formula we got:

t=\frac{54.1-53}{\frac{1.78}{\sqrt{12}}}=2.14  

P-value  

We need to find first the degrees of freedom:

df = n-1= 12-1=11

The p value for this case since we have a right tailed test is:

p_v = P(t_{11}>2.14) =0.0278
