Part B - 45% of 25 is 11.25, meaning that the price David bought the item at was $11.25. Hope that helps!
Answer: $13.75
Step-by-step explanation:
A discount of 45% off = 100% - 45% = 55% of original price
Multiply the percentage by the regular price.
0.55 * 25 = 13.75

The table shows the results of 500 experiments. Each experiment involved one person choosing one card from each of two identic decks of cards, labeled 1 through 5. What is the experimental probability of a person choosing a 2, then a 3? Express the answer as percent. ( I really need help with this, I tried looking at my notes and my brain literally can’t function )
Answers
Unfortunately, I cannot see the table you mentioned. However, I can explain how to calculate experimental probability and apply it to the given situation.
Experimental probability is the ratio of the number of times an event occurs to the total number of trials or experiments conducted. In this case, the event is a person choosing a 2, then a 3 from two identical decks of cards labeled 1 through 5.
Let's say we conducted 500 experiments, and in 50 of those experiments, a person chose a 2, then a 3. Then the experimental probability of choosing a 2, then a 3 is:
Experimental probability = (Number of times the event occurred) / (Total number of experiments) = 50 / 500 = 0.1
To express this as a percent, we simply multiply by 100:
Experimental probability as percent = 0.1 x 100% = 10%
Therefore, the experimental probability of a person choosing a 2, then a 3 from two identical decks of cards labeled 1 through 5, based on 500 experiments, is 10%.
Answer the questions below.
(a)
The perimeter of the rectangular garden is 330 m.
If the width of the garden is 77 m, what is its length?
Length of the garden: [] m.
(b)
The area of a rectangular window is 6734 cm².
If the length of the window id 91 cm, what is its width?
Width of the window [] cm.
Answers
(A):88
(B):74
Explanation:
For (A), first multiply 77 by 2 then subtract from 330
77x2=154
330-154=176
For (A), second divide 176 by 2
176/2=88
Length=88
For (B), divide 6734 by 91
6734/91=74
Hope this helps!
Answer:
(a) 88 m
(b) 74 cm
Step-by-step explanation:
You want the length of a garden with a perimeter of 330 m and a width of 77 m, and you want the width of a window with an area of 6734 cm² and a length of 91 cm.
(a) PerimeterThe perimeter of a rectangle is given by the formula ...
P = 2(L +W)
Filling in the given values, we can find the unknown.
330 = 2(L +77)
165 = L +77 . . . . . . . divide by 2
165 -77 = 88 = L
The length of the garden is 88 meters.
(b) AreaThe area of a rectangle is given by the formula ...
A = LW
Filling in the given values, we can find the unknown.
6734 = 91W
6734/91 = 74 = W
The width of the window is 74 cm.

Answers
Answer:
the answer is shown in the image below
Step-by-step explanation:
Answer:
4 1/5 or 21/5 (improper fraction)
Step-by-step explanation:
To find the area of a rectangle, there is a formula:
[tex]A=lw[/tex]
So, we know the length is 7ft, and the width is 6/10.
Substitute in the 2 values:
[tex]A=7(6/10)[/tex]
From here, you can go 2 ways:
1) Change 6/10 to a decimal, 0.6
-Then, multiply 7 x 0.6
- This equals 4.2, which as a fraction is 4 1/5 or 21/5
2) Turn 7 into a fraction, 7/1 and multiply the numerators and denominators:
- 7/1 x 6/10 = 42/10 = 21/5
Hope this helps! :)

Additional comment
The slope of the line of best fit is the ratio of the covariance of x and y to the variance of x:
m = cov(x, y)/var(x) = -7.744/10.455 ≈ -0.741

Use PEMDAS1.Do the parentheses-(These are parentheses) first
When the number it touching another number like this, you need to multiply them together

72+14x2x2
2. Then do exponents, but we don't have any so next to multiplying
2x2=4
72+14x4
14x4=56
3. Now we divide, but we don't have to divide anything so now we add

Answer:
282 cubic inches
Step-by-step explanation:
Let's have A be the top figure, B the middle, and C the bottom.
First, we need the volume for A, B, and C. And after, add them up.
Figure A : 1 · 5 · 2 = 10 cubic inches
Figure B : 3 · 3 · 8 = 72 cubic inches
Figure C : 10 · 4 · 5 = 200 cubic inches
Now we add A+B+C, so the equation is:
10+72+200=282 cubic inches
Hence, the volume of the this figure is 282 cubic inches.
A circular pool has a radius of 6 ft. What is the approximate circumference of the pool?
A. 19 ft
B. 38 ft
C. 113 ft
D. 452 ft
Answers
r = 6 ft. => C = 2π • 6 ≈ 37.7 ≈ 38 ft.
Answer: B 38 ft.
Answer: Option B. 38 ft
Step-by-step explanation:
To find the circumference of a circle, we use the formula C = 2πr, where C represents the circumference, r represents the radius of the circle, and π (pi) is a mathematical constant that is approximately equal to 3.14.
In this problem, we are given that the radius of the circular pool is 6 ft. We can substitute this value into the formula to find the circumference:
C = 2πr
C = 2π(6)
C ≈ 37.7 ft
Therefore, the approximate circumference of the pool is 37.7 feet. This is closest to answer choice B, which is 38 ft.
how to check:-17=-3x-2
Answers
Answer: x=5
Step-by-step explanation:
To solve this equation, we have to get the x alone. To cancel out the -2 on the right side, you will add 2 to both sides of the equation since -2 and 2 cancels out. Now you have -15=-3x. Now you will divide by -3 on both sides since the -3 in the equation is being multiplied by x. -15 divided by -3 equals 5. Therefore x=5.

Odessa and Randall play a game in which the highest score wins. They record their scores and plot them on the dot plots, as shown.
Based on the data, which statement about Odessa's and Randall's scores is true?
A. Odessa is generally worse at the game than Randall because her median score is lower than Randall's median score.
B. Odessa is less consistent at the game than Randall because the variability of her scores is greater than the variability of Randall's scores.
C. Randall is generally better at the game than Odessa because his median score is higher than Odessa's median score.
D. Randall is more consistent at the game than Odessa because the variability of his scores is greater than the variability of Odessa's scores.
(I got confused on the answers because of some of the repeating words)
Answers
Answer: B. Odessa is less consistent at the game than Randall because the variability of her scores is greater than the variability of Randall's scores.
Step-by-step explanation: I summed up all of Randall's scores and got 410 and then I summed up all of Odessa's scores and got 660 so that means that Odessa's scores are bigger than Randall's scores.
The data on the dot plot shows that the B. Odessa is less consistent at the game than Randall because the variability of her scores is greater than the variability of Randall's scores.
What do the dot plots show ?Odessa's scores are more spread out and less consistent than Randall's scores. This could be due to a number of reasons, such as differences in skill level, luck, or consistency in performance.
Overall, a greater degree of variability in Odessa's scores compared to Randall's scores suggests that Odessa's performance in the game is less predictable and consistent than Randall's performance.

The whole shape is a rectangle, with a length of 6 and a width of 7.
To find the area, multiply 6 by 7=42yd^2
The area of the entire shape is 42yd^2
Now, the vertical 4yd side plus the height of the dotted triangle will equal 6yd.
So the height of the dotted triangle is 6-4=2yd.
The horizontal 4yd side plus the base of the dotted triangle will equal 7yd.
So the base of the dotted triangle is 7-4=3yd.
Formula for area of triangle: 1/2 x base x height
1/2 x 4 x 3= 6yd^2
The area of the dotted triangle is 6yd^2
Now subtract the area of the whole shape by the area of the dotted triangle to get the shaded region.
42-6= 36yd^2
Area of shaded region: 36yd^2 (i think)
