Answers
The best intervals would be 41-45, 46-50, 51-55, 56-60, 61-65, and 69-70.
The best way to decide the appropriate interval would be to find the range of the numbers.
We have given a data set,
What is the smallest value in the data?The minimum is the smallest value in the data set. The maximum is the largest value in the data set.
What is the largest minus the smallest?This would be 69-42=27.
If you need six intervals you would need to round 27 up to 30 to be able to divide it out evenly and include all of the data.
The best intervals would be 41-45, 46-50, 51-55, 56-60, 61-65, and 69-70.
This way you are one over and one under the highest and lowest values.
Therefore, The best intervals would be 41-45, 46-50, 51-55, 56-60, 61-65, and 69-70.

The true statement about the equations include:
The swimmer dives to a depth of 14 feet.The swimmer comes back up 10 seconds after the timer was started.How to solve the equation?The equation given is h(t) = t² - 14t + 40. We'll factorize to get the value of t. This will be:
= t² - 14t + 40
= t² - 10t - 4t + 40
= t(t - 10) - 4(t - 10)
(t - 10) = 0.
t = 0 + 10
t = 10
In this case, the swimmer dives to a depth of 14 feet and then comes back up 10 seconds after the timer was started.

A small plane flew 808 miles in 4 hours with the wind. Then on the return trip flying against the wind it travels only 488 miles in 4 hours. What were the wind velocity and speed of the plane?
Answers
Answer:
Step-by-step explanation:
let wind velocity=x
speed of plane=y
(x+y)*4=808
x+y=808/4=202 ...(1)
(y-x)*4=488
y-x=122 ...(2)
add (1) and (2)
2y=202+122=324
y=324/2=162
from (1)
x+162=202
x=202-162=40
wind velocity=40 m/hr
speed of plane=162 m/hr

[tex]\triangle~\fbox{\bf{KEY:}}[/tex]
Divide every single term of the expression by the GCF (Greatest Common Factor).So let's divide.
But first. we should work out the GCF.
Both terms have 3x in common, so we divide both terms by 3x:
[tex]\mathrm{6x^3+3x}[/tex]
[tex]\mathrm{3x(2x^2+1)}[/tex]
To ensure that we've factored correctly, we can always use the distributive property, distribute 3x and see whether or not we end up with [tex]\mathtt{6x^3+3x}[/tex].
So the answer is
[tex]\mathrm{3x(2x^2+1)}[/tex]
Notice I put parentheses around 2x²+1. This indicates that 3x is multiplied times both 2x² and 1.

The Father of the Bride flips out when he realizes that the hot dogs and buns don't
match. There are 8 hot dogs in a package and 12 buns in a package. How many
packs of hot dogs and how many packs of buns do you need to purchase in order to
have the exact same number of each?
Answers
Using the least common multiple, it is found that you need to buy 3 packs of hot dogs and 2 packs of buns to have the exact same number of each.
How to find the number of packs needed?First, we need to find the total number of each element, finding the least common multiple of the sizes of each package, that is, 8 and 12.
The lcm is found factoring them by prime factors, hence:
8 - 12|2
4 - 6|2
2 - 3|2
1 - 3|3
1 - 1
Hence, lcm(8,12) = 2³ x 3 = 24.
Then:
24/8 = 3.24/12 = 2.Which means that you need to buy 3 packs of hot dogs and 2 packs of buns to have the exact same number of each.

A point that is exterior to an angle is found on the acute side of the angle which is true.
What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
We know that the sum of the exterior angle and interior angle is equal to 180 degrees.
"If one of the exterior angles is an acute angle, then the corresponding interior angle is an obtuse angle."

Calculating the z-score provides additional information regarding how each subject did overall as the z-score takes dispersion into account.
What is a z score?Z-score indicates how much a given value differs from the standard deviation. For example, the mean of a test could be a 73 and if a student scored an 85, that's great.
However, if the data is not spread out, that 85 could be the highest in the class by 10 points. That's much more information than just 15 points above the mean. This way you can tell when someone not only did well but did exceptionally well in comparison to his or her peers.
