While it says they are joined, we will have to solve them as seperate shapes then add the area at the end.
Since we have a half circle and a triangle, the formulas for the areas are as follows
Half-Circle
it is the regular circle formula, but divided by 2, since it is half the size of a regular circle
(pi*r^2)/2
Triangle
it is the formula for the area of a triangle, being base times height divided by 2
(b*h)/2
Plug in the numbers into the appropriate variables, then add. you should get a total area of 49.274 ft^2. Then you just multiply the final area by the $1.50 to get the cost of the mini gold course.
We have the expression
We have to convert the expression in a single-term expression. We apply the distributive property:
b) We have to substitute five different values into the expressions 5x+2x and 7x-1.
The first expression is equal to 5x+2x=7x.
We then can predict that the difference between 7x and 7x-1 is 1.
For example, for x=2, we have 7x=7*2=14 and 7x-1=7*2-1=14-1=13.
We can calculate if the two expressions can be equal, we write:
There is no value that can make both expressions equal.
Both equations have a difference of 1 for any value of x.
we have
1 donut -----> 570 calories
7 donuts ----> 600 calories
7 donuts ----> 510 calories
4 donuts ----> 480 calories
3 donuts ----> 400 calories
so
total donuts=1+7+7+4+3=22 donuts
the means is equal to
mean=(1*700+7*600+7*510+4*480+3*300)/22
mean=11,460/22
<h2>mean=521 calories</h2>
Part 2
Find out the median
order the data set from less to greater
400 400 400 480 480 480 480 510 510 510 510 510 510 510 570 600 600 600 600 600 600 600
the median is the middle of the data set
400 400 400 480 480 480 480 510 510 510 510 510 510 510 570 600 600 600 600 600 600 600
<h2>the median is 510 calories</h2>
Answer:
If we stipulate that a baby is premature if the length of pregnancy is in the lowest 4%, find the length that separates premature babies from those who are not premature. The lengths of pregnancies are normally distributed with a mean of 268 days and a standard deviation of 15 days.
hope it helps :)

Answer:
D.
Step-by-step explanation:
17% is the same as 0.17. 2/9=0.22. 0.25 doesn't need to be changed.
