Answer:
<h3>12 units squared</h3><h3>
Height= 3 units squared</h3><h3>
Base= 4 units squared</h3>
Explanation:
<h3>If you are trying to find the surface area of a figure you want to do base times height.</h3><h3 /><h3>4 squared x 3 squared = 12 squared</h3><h3 /><h3>12 units squared</h3>
Answer:
Step-by-step explanation:
in third quadrant sin is negative.
sin² θ+cos² θ=1
sin²θ+(-16/20)²=1
sin²θ+(-4/5)²=1
sinθ=±√(1-16/25)
=±√((25-16)/25)
=±√(9/25)
=±3/5
so
sin θ=-3/5
Step-by-step explanation:
Using FOIL,
(2 + √3)(1 + √3)
= (2)(1) + (2)(√3) + (√3)(1) + (√3)(√3)
= 2 + 2√3 + √3 + 3
= 5 + 3√3.
<span>In a normal distribution 68.27% of the values are within one standard deviation from the mean, 95.5% of the values are within two standard deviations from the mean, and 99.7 % of the values are within three standard deviations of the mean
With that you have the answer to the three questions:
</span>
<span>a. significantly high (or at least 2 standard deviations above the mean).
99.5% of the values are within 2 standard deviations from the mean, half of 100% - 95.5% = 4.5% / 2 = 2.25% are above the mean, so the answer is 2.25%
b. significantly low (or at least 2 standard deviations below the mean).
The other half are below 2 standard deviations, so the answer is 2.25%
c. not significant (or less than 2 standard deviations away from the mean).
As said, 95.5% are within the band of two standard deviations from the mean, so the answer is 95.5%.

Answer:
Step-by-step explanation:
Given
- The mean of the data set is 35 apples.
- Let's call
the number of apples.
The means is defined as the quotient between the sum of all elements and the total number.
Mathematically, it would be defined as
But, we know that the mean is equal to 35.
Then, we solve for
As you can see, the total number of apples depends on the sum of all elements of the data set.
For example, if the sum of all elements is 700, the total number of apples would be
Therefore, the expression that represents the total number of apples is
