Answers
Answer: The stem would be 4 and the leaves would be 1 and 6
Step-by-step explanation:
The stem would be the first number so for example in 29 the stem would be 2 and the leaves would be 9. Once you do that to each number and put them in lowest to highest order you now have your stem and leaf plot
1. In a management class, the ratio of boys to girls is 6:7; if there are 18 boys in the class. Find
the number of girls?
Answers
Explanation:
If the ratio is 6:7, and the number of boys is 18, we divide 18 by 6 to get 3. Which means 3 times 6 is 18. If we multiply the numerator by 3, we do the same to the denominator. 7・3 is 21. Therefore there are 21 girls. (The ratio is 18:21)
There are 21 girls.

The dimensions of a rectangle and a trapezoid are shown. 10 ft 8 ft 7 ft 5 ft 10 ft 20 ft Which statement is true? o The area of the rectangle is 30 square feet greater than the area of the trapezoid. The area of the trapezoid is 8 square feet greater than the area of the rectangle. The area of the trapezoid is 25 square feet greater than the area of the rectangle. The area of the rectangle is 5 square feet greater than the area of the trapezold.
Answers
STEP 1
We need to find the area of the two shapes.
\(\begin{gathered} \text{Area of rectangle = length x breadth = }8\text{ x 10 = 80 sq ft} \\ \text{Area of trapezoid = }\frac{1}{2}(upper\text{ length + lower length) x perpendicular height} \\ =\text{ }\frac{1}{2}(10+20)\text{ x }5\text{ =75 sq ft} \end{gathered}\)STEP 2
We get the difference between the 2 areas.
80 - 75 = 5 sq ft
Therefore, area of rectangle is greater than that of trapezoid by 5 sq ft (Option 4)

Step-by-step explanation:
To find the mean you first add all of the numbers together. So you would add 75+90+84+95=344. Then you would divide the sum by the amount if numbers there are. So it would be 344÷4 =86
Hope this helped :)
Answer:
x = 75, 90 , 84, 95
\(Mean = \frac{ \sum x}{n}= \frac{75+90+84+95}{4} = 86\)

Answers
The regression equation is Y = 95.0 + 0.84X.The regression line is a mathematical model that is used to predict the value of a dependent variable (Y) based on the value of an independent variable (X).
In this case, the regression line is used to predict Y from X using the following data: X = 10, 20, 30, 40, 50, 60 and Y = 111, 109, 110, 94, 92, 93. By using a regression analysis tool such as StatKey, we can calculate the regression equation that best fits this data. The regression equation is Y = 95.0 + 0.84X, where 95.0 is the intercept and 0.84 is the slope. This equation can be used to make predictions about the value of Y for a given value of X. The rounded answer for the intercept is 95.0 and the rounded answer for the slope is 0.84.

The population of a town increased from 3800 in 2007 to 6100 in 2010 find the absolute and relative (percent) increase.
Answers
The requried population increased by approximately 60.53%.
To find the absolute increase, we subtract the initial population from the final population:
Absolute increase = Final population - Initial population
Absolute increase = 6100 - 3800
Absolute increase = 2300
Therefore, the population increased by 2300 people.
To find the relative increase, we first calculate the percent change:
Percent change = (New value - Old value) / Old value x 100%
Percent change = (6100 - 3800) / 3800 x 100%
Percent change = 2300 / 3800 x 100%
Percent change = 60.53%
Therefore, the population increased by approximately 60.53%.

Find the perimeter of SQRE.
Answers
Answer: 72
Because the picture shows that there's a 90 degree angle in the bottom. We know that the bottom triangle is a 45-45-90 triangle. So the length of one side is 18 because a 45 45 90 triangle has two sides that are equivalent (x) and one side that is x\(\sqrt{2} \\). So now that we know the length of one side is 18, we know the lengths of all 4 sides. Adding them up ( 18 + 18 + 18 + 18) gives 72, which is the perimeter.

there are 9 red markers, 5 blue markers, 14 yellow markers, and 8 green markers in a pencil box. A marker is chosen at random, replaced, then another is chosen. Find each probability.
P(yellow, then red)
P(blue, then green)
P(both red)
Answers
We will see that the probabilities are:
P(yellow, then red) = 0.1P(blue, then green) = 0.03P(both red) = 0.06How to find the probabilities?
First, the probability of getting a particular color of marker is given by the quotient between the number of markers of that color and the total number of markers
There are:
9 red markers.
5 blue markers.
14 yellow markers
8 green markers.
For a total of: 9 + 5 + 14 + 8 = 36.
a) P(yellow, then red)
First, the probability of getting a yellow marker is:
p = 14/36.
Then the probability of getting a red marker (notice that now there are 35 markers in total) is:
q = 9/35.
Then the joint probability is:
P(yellow, then red) = p*q = ( 14/36)*(9/35) = 0.1
b) P(blue, then green)
First, the probability of getting a blue marker is:
p = 5/36.
After, the probability of getting a green marker is:
q = 8/35.
So the joint probability is:
P(blue, then green) = (5/36)*(8/35) = 0.03
c) P(both red).
First, the probability of getting a red marker is:
p = 9/36
Now there are 8 red markers and 35 markers in total, so the probability of getting another red marker is:
q = 8/35
The joint probability is:
P(both red) = (9/36)*(8/35) = 0.06

Using the Pythagorean theorem, we can find the length of HG:
HG² = HI² + IG²
Therefore, the length of HG is 5sqrt(3) units.
What is pythagorean theorem?The Pythagorean Theorem is a mathematical formula that states in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
What is Length?Length is a measurement of the extent of something along its longest dimension, from one end to the other. It is often expressed in units such as meters, feet, or inches.
According to the given information:
To calculate the length of HG, we can use the Pythagorean theorem, which states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of its two legs.
First, we can identify that triangle HGN is a right triangle, with HG being the hypotenuse. Using the Pythagorean theorem, we have:
(HG)² = (NG)² + (NH)²
We can also identify that triangle INH is also a right triangle, with IN being the hypotenuse. Using the Pythagorean theorem, we have:
(IN)² = (NH)² + (NI)²
Substituting (NH)^2 from the second equation into the first equation, we get:
(HG)² = (NG)² + (IN)² - (NI)²
Plugging in the values given in the diagram, we get:
(HG)² = 5² + 9² - 3²
(HG)² = 61
HG = √61
Therefore, the length of HG is the square root of 61.

Use pencil and paper. Explain how you know that the relationship between the hedgehog's weight loss and the number of days of hibernation is proportional.
Answers
Using the principle of proportional relationship, the amount of weight lost by hedgedog in 120 days is 3.6 oz
Proportional relationships are defined thus :
y = kx k = constant of proportionalityTaking a piar of points :
-0.24 = 8k
Divide both sides by 8
(-0.24/8) = k
k = - 0.03
Hence, hedgedog loses weight at a rate of - 0.03 oz per day.
The amount of weight lost in 120 days :
The proportional relationship = y = - 0.03x
Substitute x into the equation
y = -0.03(120)
y = - 3.6 oz
Therefore, the amount of weight lost in 120 days is 3.6 oz.

How tall is a pole if a 40 ft guy wire reaches from the top of that pole

Answers
Step by step
Using Pythagorean theorem
a^2 + b^2 = c^2
We are looking for the height “a”
We know b= 19, c= 40
So we can substitute know numbers into the equation and solve
a^2 + 19^2 = 40^2
Subtract 19^2 from both sides
a^2 = 40^2 - 19^2
a^2 = 1600 - 361
a^2 = 1239

Step-by-step explanation:
The perimeter is the sum of the side lengths. Each of the lower-right and lower-left indents can be reversed to make the figure a 20 m by 25 m rectangle without changing the perimeter. Then the perimeter is ...
P = 2(L +W)
P = 2(25 m + 20 m) = 2(45 m)
P = 90 m
_____
If you start at the upper left corner and work clockwise, the perimeter is the sum of segment lengths ...
P = 20 m + 5 m + 8 m + 20 m + 4 m + 20 m + 8 m + 5 m
P = 90 m

The units must be given as part of the measurement of the perimeter. That is why choice B (90) is inappropriate.
