2400/6= 400
4000/10= 400
5200/13= 400
y=400x
Every star is 400 points and the independent variable is number of stars Brian picks up because the amount of points he gets is dependent on the number of stars he has.
Answer:
pic # 1 answer is B. 81 x pi
pic#3 answer is C. QC
Step-by-step explanation:
pic #1
the formula to find the area of a circle is pi x the radius to the second power
they give you the diameter. (18)
the radius is half of a diameter (d/2)
so 18/3 = 9
9 to the second power (9 x 9) = 81
so your answer is 81 x pi
pic#2
I don't much, but i do know they asking for the radius and since the radius is half the diameter of a circle then QC makes sense in my book.
hope this is helpful.
Hi fren,
x=<span><span>−y</span>+<span>1
and for the second one...
</span></span>y=<span><span>2x</span>+<span>2
</span></span>x-intercept >> <span>(<span><span>−1</span>,0</span>)
</span>y-intercept >> <span>(<span>0,2)</span></span><span>

Answer:
18x + 15
Step-by-step explanation:
Combine like terms & simplify the given expression:
9x - 4 + 4x + 5x + 19
(9x + 4x + 5x) - 4 + 19
(13x + 5x) + (19 - 4)
(18x) + 15
18x + 15 is your answer.

Answer:
P-value = 0.0367
Step-by-step explanation:
This is a hypothesis test for a proportion.
The claim is that the percentage of residents who favor construction is significantly over 42%.
Then, the null and alternative hypothesis are:
The sample has a size n=900.
The sample proportion is p=0.45.
The standard error of the proportion is:
Then, we can calculate the z-statistic as:
This test is a right-tailed test, so the P-value for this test is calculated as:
