Answer:
Step-by-step explanation:
12n2+48n=−n3−64
Step 1: Subtract -n^3-64 from both sides.
12n2+48n−(−n3−64)=−n3−64−(−n3−64)
n3+12n2+48n+64=0
Step 2: Factor left side of equation.
(n+4)(n+4)(n+4)=0
Step 3: Set factors equal to 0.
n+4=0
n=−4
Should be a!
26^2 - 22^2 = 192, take the sqrt of that C:
They will each have 2.5 fruit bars
I would have to say (B) ! Good Luck :D
Answer:
Step-by-step explanation:
) Do you expect the distribution of number of friends made online to be symmetric, skewed to the right, or skewed to the left?
Skewed to the left.
Symmetric
Skewed to the right.
(b) Two measures of center for this distribution are 1 friend and 5.3 friends. Which is most likely to be the mean and which is most likely to be the median?
Mean=
Median=
<h2>----------------------------------</h2>
a)
as proportion of people with 0 friends is 43% whcih is on left side and maximum ; and % decrease with increasing number of friends
skewed to the right
b)
as it is skewed to the right ; therefore mean is greater than median
mean=5.3
median=1
[since for skwewed to the right distribution :mean is always greater than median, therefore higher value should be mean which is 5.3 and lower value is median which is 1]
