Answer:
<em>5.48</em>
<em></em>
Step-by-step explanation:
Given length of three strings:
To find:
The difference in length between the longest and the shortest string?
Solution:
First of all, let us compare the given three decimal numbers.
We check the number before decimal first of all.
We can see that the numbers are 7, 3, and 2.
7 being the largest is the longest string.
2 being the smallest is the shortest string.
So, the difference is:
So, the answer is <em>5.48.</em>
Answer:
6 seconds
Step-by-step explanation:
h(x)=-(x-2)^2+16
We want h(x) to be 0 ( that is when the ball hits the ground)
0 = -(x-2)^2+16
Subtract 16 from each side
-16 = -(x-2)^2+16-16
-16 = -(x-2)^2
Divide by -1
16 = (x-2)^2
Take the square root of each side
sqrt(16) = sqrt((x-2)^2)
±4 = x-2
Add 2 to each side
2±4 = x-2+2
2±4 =x
2+4 = x 2-4 = x
6 =x -2 =x
Time cannot be negative so x=6
Answer:
56 because a triangle is always 90 degrees so 90 minus 22 plus 12 equals 56
Step-by-step explanation:
Answer:
d. No, the conditions for normality have not been met because the sample size for the pennies is not large enough and no information is given about the distributions of the populations.
Step-by-step explanation:
In this example, we learn that the sample taken of pennies was of 25, while the sample of quarters was of 35. According to the central limit theorem, a sample must be equal to or larger than 30 for the theorem to hold. The theorem states that when random variables are added, they tend towards a normal distribution even if the original variables themselves are not normally distributed. In this question, the sample of pennies is not large enough for the theorem to hold. On top of this, we have no information about the distribution of the populations. Therefore, the conditions for normality have not been met.
