The proportion of the generated values that fall inside the range of each histogram bar is used to compute the vertical scale. The standard deviation is an indicator of how much the values in the data set typically deviate from the mean.
What is the difference between standard deviation and histogram?It always displays the median and the middle 50% of the data. For data displayed in histograms, a similar spread measurement is helpful. The term for it is the standard deviation. The standard deviation is an indicator of how much the values in the data set typically deviate from the mean.
The proportion of the generated values that fall inside the range of each histogram bar is used to compute the vertical scale. The sum of the bar heights is therefore one. Only discrete variables (right), where the histogram heights now total to unity, are suitable for relative frequency analysis.
A measurement of how far points deviate from the mean is the standard deviation. The first histogram includes fewer points that are close to the mean and more points that are distant from the mean (scores of 0, 1, 9, and 10). (scores of 4, 5 and 6). As a result, its standard deviation will be higher.

You drive 3 hours to reach the waterpark. Driving home along the same route, you increase your
speed by 20 miles per hour, reducing your drive time by 1 hour. Write and solve an equation to find
how fast you were driving to the waterpark.
Answers
The initial speed to the waterpark is 40 miles/hr.
The return speed is 60 miles/hr.
How to find the speed?
Given,
t = 3hr
Return speed = s +20m
Return time = 3 -1 = 2hrs
Solution:
s = d/t
s = d/3
d = 3s----1
s + 20 = d/t - 1
s + 20 = d/3-1
s + 20 = d/2
2s + 40 = d------2
Equating equations 1 and 2,
3s = 2s + 40
s = 40 miles/hr
The initial speed to the waterpark is 40 miles/hr.
Return speed = s +20
= 40+20
= 60 miles/hr
The return speed is 60 miles/hr.

g(x) = x2 − 5x
h(x)= 4x + 4
Find (g ◦ h) (x)
Answers
Answer:
(g ◦ h) (x) = 16x² + 12x -4
Step-by-step explanation:
We have
g(x) = x² − 5x
h(x)= 4x + 4
(g ◦ h) (x) = g(h(x))
h(x) = 4x + 4
g(h(x)) = g(4x + 4)
= (4x + 4)² - 5(4x+4) //substitute 4x + 4 wherever there is an s-term in
(4x + 4)² = 16x² + 32x + 16
5(4x + 4) = 20x + 20
(4x + 4)² - 5(4x+4) = 16x² + 32x + 16 -(20x + 20)
= 16x² + 32x + 16 - 20x - 20

the cost of 12 hot dogs and 8 fry portions is £52. The cost of 8 hot dogs and 12 fry portions is £48. What is the total cost of a hot dog and a portion of fries?
Answers
Answer:
Hot dogs cost £3 and fry's cost £2.
Total cost £5.
Step-by-step explanation:
Let a hot dog cost £x and a portion of fry's cost £y.
Then:
12x + 8y = 52
8x + 12y = 48
Simplifying these 2 equations we get:
3x + 2y = 13 ---------- (A)
2x + 3y = 12...............(B)
multiply the first equation by 2 and the second by 3:
6x + 4y = 26
6x + 9y = 36
Subtracting:
0 - 5y = -10
y = -10/-5 = 2.
Now, substituting in equation (A):
3x + 2(2) = 13
3x = 9
x = 3.

What is a parallelogram?A parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.
Given that parallelogram ABCD, has m∠ABC = 135° and the length of diagonal AC is 41 units.
The measure of length of side AD is 35 units and length of side AB is 7 units.
WE know that the opposite side of a parallelogram are same. Thus,
The length of segment CD = AB = 7 units.
Also, the length of diagonal AC = 41 units. Then;
The length of segment AE = 1/2 AC = 41/2 = 20.5 units.
Therefore, m∠BCD + m∠ABC = 180
m∠BCD + 135 = 180
m∠BCD = 180 - 135
m∠BCD = 45 degrees.
Hence, The length of segment CD is 7 units. The length of segment AE is 20.5 units. The m∠BCD is 45 degrees.

1110800. Equity Account will be after stock dividends
What is stock dividend ?Similar to a cash dividend, however instead of cash, stocks are given out. A stock dividend will increase the number of shares outstanding while lowering the stock price.
In this issue, there are 460000 shares outstanding at a price of $30, which equals 13800000
Equity's total market value is $13800000.
Each shareholder will get a 20% increase in stock, and the number of existing shares will increase as a result of the 20% stock dividend.
Shares outstanding after dividend announcement total 460000 + 46000 ×20% =552000.
The number of outstanding common shares will rise to 552000 as a result of the issuance of 92000 more shares.
Common stock only contains the par value; for example, if the market price of a share is $30 and the par value is $1, the excess amount of $29×92000:2668000 is added to the capital surplus account. It will total 861000 + 2668000=3529000.
Due to the absence of any monetary transactions, the total owners' equity is unaltered.
The retained earnings will be decreased by 92000 × 30 = 2760000, resulting in 3870800 – 2760000=1110800.
Equity Account will be after stock dividends.

Answers
Using division, If you have 7/8 of a cup of tomato sauce and you must fill small containers with exactly 1/4 of a cup of tomato sauce, then number of containers can fill completely is 3 containers
The total quantity of tomato sauce that you have = 7/8 of a cup
The quantity of tomato sauce with you must fill small containers = 1/4 of a cup
To find the number of containers that you can fill completely, you have to use division
Number of containers can fill completely = The total quantity of tomato sauce that you have / The quantity of tomato sauce with you must fill small containers
= 7/8 ÷ 1/4
= 7/8 × 1/4
= 7/2
= 3.5

Answers
Answer:

Explanation :
Let us call x, the woman speed as she goes uphill
Now, we know that it took the woman 2 hours to go uphill; therefore, the distance covered is
4* (x)
shortly afterwards, when the woman returns she is walking at x + 2 mph; therefore, the distance she covers is
D = 4 (x +2 )
Since the uphill and the downhill distances ar the same, we have
4x = 2 (x +2 )
4x = 2x + 4
x = 2
Hence, going to the hill, the woman speed is 2 miles per goo
