Answer:
C because 4 times 3x is 12x, and 4 times 4x is 16x
Answer:
First box = 22.5, 45/2, or 22 and 1/2
Second box = square inches (because area is always ^2, or squared)
Step-by-step explanation:
A = B * H
B = base
H = height
Base = 5 inches
Height = 4.5 inches
5 inches * 4.5 inches = 22.5 inches^2
This can also be written as 45/2 or 22 and 1/2

Answer:
Step-by-step explanation:
Given that an automatic machine is set to fill bags of dog food with exactly 25 pounds on average with a standard deviation of 0.5 pounds.
Sample size = n =100
x bar = 24.85 pounds
Sample std error = 
Hypotheses:
(Two tailed test at 5% level)
Mean difference =0.15
Test statistic = mean diff/se = 3
Since population std dev is known z test can be used
p value =0.0000
Since p <0.05 we find that the bag does not contain exactly 25 pounds.
We know that
a(n)=4n+1
To find the sum of the first n<span> terms of an arithmetic series
use the formula
</span><span><span>Sn</span>=<span>n(<span>a1</span> + <span>an</span>)/2
</span></span>a1--------------> is the first term
an--------------> is the last term
n--------------- > <span>is the number of terms
</span>we have that
a1------------> 4*(1)+1=5
a30----------> 4*(30)+1=121
n------------- > 30
S30=30*(5 + 121)/2=1890
the answer is 1890
29 = 1 * 29
1 + 29 = 30
thus answer is 29
