Answer:
Option C or 56.25×πcm^2
Step-by-step explanation:
The formula to find the circumference of a circle is P=2×π×r.
The formula to find the area of a circle is A=π×r^2.
Step 1: Find the radius by expanding your circumference answer to get the entire formula. In this case 15π=2×π×7.5 Look familiar? You have found the radius!
Step 2: Put the radius in the formula to find the area. Since this answer is not looking for a specific number that's all you have to do. In this case, A=π×7.5^2. Or A=π×56.25.
Step 3: You have the answer. Hope this helps
You can find the answer by finding the area of the smaller shape and subtracting it from the bigger shape.
<u>
Larger Shape</u><u />
1/2bh=1/2*5*12=30
<u>Smaller Shape</u><u />
1/2bh=1/2*4*3=6
<u>Shaded Area</u><u />
30-6=24
The area of the shaded region is 24mm squared.
The 85th percentile is the cutoff time
such that
In other words, the 85th percentile refers to the time needed to belong to the top 15% of the distribution; more generally, the
percentile is the top
of the distribution.
Anyway, to find this value of
, transform
to a random variable
with the standard normal distribution using
where
is the mean of
and
is the standard deviation of
.
Here
is used to denote the z-score corresponding to the cutoff time
. Referring to a z-score table, you find that this occurs for
. So,
Answer:
yo yo yo what's the dealio I no the answer for sho
The answer is C, four
because the answer before the line is the ten so the 7 is a 70
the number after the line is a unit, so a 6 is a 6
so the number would be 76
all the numbers before 70 you just have to count
and there is 4, so its C
