<span>Pattern did the power of 4 shows:
Let’s have an example of the power of 4
=> 4 will be multiplied 4 times
=> 4 x 4 = 16
=> 16 x 4 = 64
=> 64 x 4 = 256
=> 256 x 4 = 1024
=> 1024 x 4 = 4096
=> 4096 x 4 = 16384
………………..
Did you notice the pattern? The last number of each answer always ends up with
4 and followed by 6.</span>
Answer:
Step-by-step explanation:
We would set up the hypothesis test. This is a test of a single population mean since we are dealing with mean
For the null hypothesis,
µ = 12
For the alternative hypothesis,
µ < 12
Since the population standard deviation is given, z score would be determined from the normal distribution table. The formula is
z = (x - µ)/(σ/√n)
Where
x = sample mean
µ = population mean
σ = population standard deviation
n = number of samples
From the information given,
µ = 12 minutes
x = 8 minutes
σ = 12 minutes
n = 36
z = (8 - 12)/(12/√36) = - 4/2 = - 2
Test statistic = - 2
Answer:
226.9 in²
Step-by-step explanation:
The formula for circumference of a circle is:
C = 2πr, where π = 3.14 and r = the radius
The formula for area of a circle is
A = πr²
First, using the formula for circumference, you can solve for 'r':
53.42 = 2πr or 53.42 = 6.28r (divide) r = 8.5
Now, use the value of 'r' to solve for area:
A = π8.5² or 3.14(8.5)² = 226.9 in²
A.
14+x
B. 6y
Hope I helped!
A^2 + b^2 = c^2
a=6
b=8
36 + 64 = 100
Sqrt 100 = 10
A is the answer
