14. What is the difference between
70% of 7 and 7% of 70?
Answers
Answer:
It's technically the same thing, because if we solve both of these the answer would be same.
First one says 70 percent part of 7 and the other one says 7 percent part of 70. However, if we solve both of these the answer will be same:
i) 70% of 7
= (70/100) × 7
= 4.9 answer
ii) 7% of 70
= (7/100) × 70
= 4.9 answer
So, here as you can see, through both the equations we get the same answer, which is 4.9 .
This is one of the basic principles of multiplication actually, where:
a × b = c
b × a = c
Therefore,
a × b = b × a

A manager drew this box-and-whisker plot to represent the weights, in pounds, of the 440 crates the company is shipping. box-and-whisker plot ranging from 80 to 180 with ticks at increments of 2.5. plot defined by points at 84, 99.5, 113, 143, 170. how many crates weigh more than 99.5 pounds? select from the drop-down menu to correctly complete the statement. about choose... crates weigh more than 99.5 pounds.
Answers
Deducing from the considered box plot, the number of crates that weigh more than 99.5 pounds is 330 approx.
How does a boxplot shows the data points?A box plot has 5 data description.
The leftmost whisker shows the minimum value in the data.The rightmost whisker shows the maximum value in the data.The leftmost line in the box shows the first quartile.The middle line shows the median, also called second quartile.The last line of the box shows the third quartile.What are quartiles?When we get data which can be compared relatively with each other, for finding quartiles, we arrange them in ascending or descending order.
Quartiles are then selected as 3 points such that they create four groups in the data, each groups approximately possessing 25% of the data.
Lower quartile, also called first quartile has approx 25% in its left partition, and on its right lies approx 75% of the data.Similarly, second quartile (also called median) is approximately in mid of the data.Third quartile (also called upper quartile) has approx 75% in its left partition, and on its right lies approx 25% of the data.Left to right is said in assumption that data was arranged increasingly from left to right
We're specified here that:
Total 440 crates is being shipped by company.
The box plot is defined by the points 84, 99.5, 113, 143, 170
The point 99.5 is the first quartile.
There are 75% observations on its right, so 75% of 440 is the number of crates which weigh greater than 99.5 pounds.
We get this value as:
[tex]\dfrac{440}{100} \times 75=330[/tex]
Thus, deducing from the considered box plot, the number of crates that weigh more than 99.5 pounds is 330 approx.

Simplify the square root of 40x^4
Answers
Answer:
4 = 22
Step-by-step explanation:
Factor 40 into its prime factors
40 = 23 • 5
To simplify a square root, we extract factors which are squares, i.e., factors that are raised to an even exponent.
Factors which will be extracted are :
4 = 22
Factors which will remain inside the root are :
10 = 2 • 5
To complete this part of the simplification we take the squre root of the factors which are to be extracted. We do this by dividing their exponents by 2 :
2 = 2
At the end of this step the partly simplified SQRT looks like this:
2 • sqrt (10x4)
Rules for simplifing variables which may be raised to a power:
(1) variables with no exponent stay inside the radical
(2) variables raised to power 1 or (-1) stay inside the radical
(3) variables raised to an even exponent: Half the exponent taken out, nothing remains inside the radical. examples:
(3.1) sqrt(x8)=x4
(3.2) sqrt(x-6)=x-3
(4) variables raised to an odd exponent which is >2 or <(-2) , examples:
(4.1) sqrt(x5)=x2•sqrt(x)
(4.2) sqrt(x-7)=x-3•sqrt(x-1)
Applying these rules to our case we find out that
SQRT(x4) = x2
sqrt (40x4) =
2 x2 • sqrt(10)
Simplified Root :
2 x2 • sqrt(10)

Answer:
Angle 6= 109
Angle 6= 71
Step-by-step explanation:
Angle 4 and Angle 2 are equal because they are vertical angles, Angle 2 is also 109, Angle 6 is corresponding to angle 2, meaning angle 6 is also 109. To figure out angle 7 you simply do 180-109=71 and you get 71 for angle 7
Answer:
Step-by-step explanation:
<6 is the same since they are alternate interior angles meaning <6 is 109 degrees
7 is going to be a little more complicated.
180-109=71
<1,2,3 and 4 all share similar angles. 1 and 3 are similar, meaning 2 and 4 are also.
If 2 is 4 (109), then this means that 7 is 109 as it is the alternate exterior angle.

What is probability of an event?Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.
You spin the spinner two times.
If you get blue both times, you win $15. If you don't, you lose $2.Let suppose there are total 12 outcomes on a spinner which has 12 blocks. In this block, 4 is blue. The probability of getting blue twice in this spinner and earning $15 is,
[tex]P=\dfrac{4}{12}\times\dfrac{4}{12}\\P=\dfrac{1}{9}[/tex]
The probability of not getting two blue in two spun and losing $2 is,
[tex]P^{-1}=1-\dfrac{1}{9}\\P^{-1}=\dfrac{8}{9}[/tex]
The money to expect to win or lose if you play this is,

D A $220 bill totals $237.60 with fee
E A $410 bill totals $418.20 with fee
Answers
Because a and c have late fees that are greater than 5%
( hope this helps )
Reason:
A. 150 • 5 = 750 750/100 = 7.5
150 + 7.5 = 157.5
157.5 > 154.50, so 154.50’s fee is less than 5%.
B. 40 • 5 = 200 200/100 = 2
40 + 2 = 42
42 > 41.60, so 41.60’s fee is less than 5%.
C. 120 • 5 = 600 600/100 = 6
120 + 6 = 126
126 < 133, so 133’s fee is more than 5%.
D. 220 • 5 = 1100 1100/100 = 11
220 + 11 = 231
231 < 237.60, so 237.60’s fee is more than 5%.
E. 410 • 5 = 2050 2050/100 = 20.50
410 + 20.50 = 430.50
430.50 > 418.20, so 418.20’s fee is less than 5%

Answers
The probability that at least one of the sides of the triangle is also a side of the octagon is 5/7
How to determine the probability?A regular octagon has 8 sides, and a triangle has 3 sides
Assume that there is a point on the triangle.
Then we select (3 - 1) points from the (8 - 1) sides.
8 - 1 = 7
3 - 1 = 2
So, the total number of selection is:
Selection = 7C2
Evaluate the combination expression
Selection = 21
Adjacent triangles have 5 lines (one line in common).
So, we have:'
n = 5 - 1
n = 4
The number of ways this points can be selected is:
Selection = 4C2
Evaluate
Selection = 6
The probability that the triangle and the octagon do noth have the same side is:
P= 6/21
The probability that at least one of the sides of the triangle is also a side of the octagon is calculated using the following complement rule
P = 1 - 6/21
Evaluate the difference
P = (21 -6)/21
P = 15/21
Reduce fraction
P = 5/7
Hence, the probability that at least one of the sides of the triangle is also a side of the octagon is 5/7

Write the equation of the line that is perpendicular to the line which has a slope of 3 / 4 and passes through the point ( 0, - 4 ).
Answers
Answer:
y=-4/3x-4
Step-by-step explanation:
The equation of the line that is perpendicular to the line which has a slope of 3 / 4 and passes through the point ( 0, - 4 ) is equals to [tex]y= \frac{-4}{3} x-4[/tex]
What is equation of line?" Equation of line is defined as the equation which represents the set of points using slope."
Formula used
[tex]y=mx+c[/tex]
m = slope of the line
c = y-intercept
Product of the Slopes of perpendicular lines = -1
According to the question,
Slope of the given line = [tex]\frac{3}{4}[/tex]
Using condition for slope of perpendicular lines we have,
Slope of the line perpendicular to the given line 'm' = [tex]\frac{-4}{3}[/tex]
From given point (0, -4)
Y- intercept 'c' = -4
Substitute the value in the formula to get equation of required line,
[tex]y= \frac{-4}{3} x-4[/tex]
Hence, equation of the line that is perpendicular to the line which has a slope of 3 / 4 and passes through the point ( 0, - 4 ) is equals to [tex]y= \frac{-4}{3} x-4[/tex].
