An architect plans to build an extension to Meiling's rectangular deck. Let x represent the increase, in meters, of her deck's length. The expression 2(x + 7) represents the area of the deck, where 2 is the width, in meters, and (x + 7) represents the extended length, in meters. Use the Distributive Property to write an expression that represents the total area of Meiling's new deck.
Answers
The expression should be 2x + 14
Calculation:Since 2 is the width, in meters, and (x+7) represents the extended length, in meters.So, area is:
\(A = 2(x+7)\)
And,
\(A=(2\times x) + (2 \times 7)\)
\(A = 2x + 14\)

x<−56
Answers
Answer: x> 2.33
None of the answer choices listed are correct.
Step-by-step explanation:
The inequality can be solved by adding 12x to both sides and then subtracting 10 from both sides:
10 - 12x + 12x < -18 + 12x
10 < -18 + 12x
Now we subtract -18 from both sides:
10 - (-18) < -18 + 12x - (-18)
28 < 12x
Finally, we divide both sides by 12:
28/12 < 12x/12
2.33 < x
So, the solution to the inequality 10 - 12x < -18 is x > 2.33.

A survey at the local fair asked people of different ages about their favorite game to play. The results are displayed in the two-way relative frequency table below:
Ages

Whack-a-Mole l 5 1 3
Ball Throw l 2 7 4 2
Ring Toss l 4 2 5 9
Suppose someone likes to play the Flip-Frog game. What is the conditional frequency they are between 18 and 22 years old? If needed, round answer to the nearest tenths.
A. 37.5%
B. 9.1%
C. 18.2%
D. 12.5%
Answers
Answer:
Step-by-step explanation:
To find the conditional frequency of someone who likes Flip-Frog game and is between 18 and 22 years old, we need to use the formula:
Conditional frequency = (Frequency of Flip-Frog players between 18 and 22) / (Total frequency of Flip-Frog players)
From the table, we see that the frequency of Flip-Frog players between 18 and 22 is 4, and the total frequency of Flip-Frog players is 9+4+12=25.
Therefore, the conditional frequency of someone who likes Flip-Frog game and is between 18 and 22 years old is:
Conditional frequency = 4 / 25 = 0.16 = 16%
Rounding to the nearest tenth, we get:
Conditional frequency = 16.0%
So, the answer is not one of the options given.

Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)
PLEASE HELP ASAP !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answers
Part A: To calculate the measures of center, we can find the median and the mean for each school.
For Bay Side School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 25, so the median class size is 25.
To find the mean class size for Bay Side School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 12 + 12 + 12 + 14 + 15 + 15 + 16 + 16 + 18 + 18 + 20 + 20 + 23 + 25 + 25 = 243. There are 15 classes, so the mean class size is 243/15 ≈ 16.2.
For Seaside School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 15, so the median class size is 15.
To find the mean class size for Seaside School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 10 + 10 + 10 + 11 + 12 + 15 + 15 + 16 + 17 + 17Part A (continued):
18 + 18 + 20 + 20 + 25 = 222. There are 14 classes, so the mean class size is 222/14 ≈ 15.9.
Therefore, the measures of center for Bay Side School are: median = 25, mean ≈ 16.2.
The measures of center for Seaside School are: median = 15, mean ≈ 15.9.
Part B: To calculate the measures of variability, we can find the range and the interquartile range (IQR) for each school.
For Bay Side School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 12, so the range is 25 - 12 = 13.
To find the IQR for Bay Side School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 15 and Q3 is 20. Therefore, the IQR is 20 - 15 = 5.
For Seaside School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 10, so the range is 25 - 10 = 15.
To find the IQRPart B (continued): for Seaside School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 12 and Q3 is 18. Therefore, the IQR is 18 - 12 = 6.
Therefore, the measures of variability for Bay Side School are: range = 13, IQR = 5.
The measures of variability for Seaside School are: range = 15, IQR = 6.
Part C: If you are interested in a smaller class size, Seaside School is a better choice because its measures of center are lower than those of Bay Side School, indicating that its class sizes tend to be smaller on average. Additionally, Seaside School has a smaller range and IQR, indicating less variability in class size. Therefore, there is less chance of encountering very large classes at Seaside School compared to Bay Side School.

Answer:
Y= mx + b
so Y = 1/3x + 2
just substitute
Now, we shall use points (3,2) as the substitutes for the solution for b, which 3 would be the input and 2 would be y.
Therefore, 2 = 1/3(3) + b
2 = 1 + b, therefore, one would be subtracted from 2 which would give us the answer of b equaling to one. Thus, y = 1/3x + 1
If you roll a fair number cube 30 times, what is the experimental probability of rolling a 2
Answers

Step-by-step explanation:
a fair number cube has six sides so if you roll that 30 times that's 180 sides and the probability of rolling a 2 out of a single dice is 1/6 and since 180 * 1/6 is equal to 30 that is 30 out of 180 which is 1/6

Find the x- and y- intercepts of this two-variable equation:
y = 5 + x
Answers
To find the x-intercept, we set y = 0 and solve for x:
0 = 5 + x
Subtracting 5 from both sides:
x = -5
Therefore, the x-intercept is -5.
To find the y-intercept, we set x = 0 and solve for y:
y = 5 + 0
Simplifying:
y = 5
Therefore, the y-intercept is 5.
The x-intercept is (-5, 0).
The y-intercept is (0, 5).
Answer:
x: -5,0
y: 0,5
Step-by-step explanation:
y=0
0=5+x
x=-5
x=0
y=5+0
y=5
