114.8ft
The formula for a trapezoid is ((a+b/2)h
You need to plug everything in, ((12+15)/2)8.5= 114.8
Answer:
114.8 ft²
Step-by-step explanation:
Understanding the given values :
bases (a and b) = 12 feet and 15 feetperpendicular distance (height, h) = 8.5 feetInputting into the formula for the area of a trapezoid :
A = 1/2 x (a + b) x hA = 1/2 x (12 + 15) x 8.5A = 4.25 x 27A = 114.8 ft² (nearest tenth)The tables show the ages of the finalists for two reality singing competitions.
Two tables. The table on the left is titled Ages for Show A. The values in this table are 18, 17, 15, 21, 22, 16, 18, 28, 24, 21. The table on the right is titled Ages for Show B. The values in this table are 21, 20, 23, 13, 15, 18, 17, 22, 36, 25.
a. Find the mean, median, range, and interquartile range of the ages for each show. Round to the nearest tenth. Compare the results.
Answer:
Step-by-step explanation:
The Table on the left Ages for Show A
18+17+15+21+22+16+18+28+24+21 = 200 divided by 10 = 20 = Mean
Median: 15, 16, 17, 18, 18, 21, 21, 22, 24, 28
19.5 = Median
Mode: 18 and 21

A regular-size box of crackers measures 2 inches by 9 inches by 14 inches. The manufacturer also sells a snack-size box that has a volume that is 1/4 of the volume of the regular-size box. What is the volume of the snack-size box
Answer:
63
Step-by-step explanation:
2 x 9 x 14 = 252, 1/4 of 252 is 63
Answer:
63 in³
Step-by-step explanation:
Volume of regular box = width × length × height
= 9 × 14 × 2
= 252 in³
If the snack box is 1/4 of the volume of the regular-size box, to find the volume of the snack box, multiply the volume of the regular-size box by 1/4:
Volume of snack box = Volume of regular box × 1/4
= 252 × 1/4
= 252 ÷ 4
= 63 in³

A bag contains 8 red pens, 7 blue pens, and 14 black pens. Denato will pull a pen from the bag. Write two different scenarios: one that is a dependent event and one that is an independent event.
Answer:P(red) = 4/15 P(black) = 6/15 P(red or black) = 4 / 15 + 6 / 15 = 10 / 15 = 2 / 3
Step-by-step explanation
big math
Answer:
Dependent: Denato will pull three pens from the bag to see if he'll get the same color three times since the chances become less likely.
Independent: Denato will pull three pens from the bag, replacing the color he pulled each time.

In Mrs. Santiago’s math classroom, more people sit on the right-hand side of the room than the left. The students on the right-hand side of the classroom received the following scores on an exam worth 100 points:
85, 90, 100, 95, 0, 0, 90, 70, 100, 95, 80, 95
The students who sit on the left side of the room received these test scores on the same test:
65, 80, 90, 65, 80, 60, 95, 85
1) Make a statistical argument that students on the right-hand side of the
room were more successful.
2) Make a statistical argument that students on the left-hand side of the
room were more successful.

Answer:
[tex]4a^{10}[/tex]
Step-by-step explanation:
[tex]\textsf{Given expression}:[/tex]
[tex](a^2)^5 \cdot 4^3 \cdot 4^{-2}[/tex]
[tex]\textsf{Apply radical rule} \quad a^b \cdot a^c=a^{b+c}:[/tex]

math pls help due tmmr
Answer:
Step-by-step explanation:
First you have to arrange the numbers from least to greatest on the line, then add one dot for each data point. For questions 2 and 3, it’s just the left and right ends of the plot. Question four is how many dots you put over the 3 1/4 place. Question 5 is the lowest plus five and the highest minus five. I hope that helps!!

Answer:
x = 5.7
Step-by-step explanation:
6.3+6.3+2.6+2x = 26.6
12.6+2.6+2x = 26.6
15.2+2x = 26.6
2x = 11.4
x = 5.7
Find the Surface Area of the Pyramid. Round to the NEAREST TENTH.
Answer:
Step-by-step explanation:
The side triangles are: 352.35
Middle triangle is: 113.4
352.35 + 113.4 = 465.75
Answer:
465.75 or 465.8 rounded to the nearest tenth
Step-by-step explanation:
You would multiply 16.2 and 14.5 and divide by 2 to get 117.45. You then multiply by 3 for the 3 sides to get 352.35. Lastly, to find the area of the base you would need to multiply 16.2 and 14 and divide it by two to get 113.4. Add it with the 3 sides and you get 465.75.

Answer:
1/2 (one half) or 0.5
Step-by-step explanation:
Three is half of six, so the probability that it will be checkered is exactly one half. Lets say you have six papers in a hat, and you drew on three of them. In that scenario, you have one half chance of getting a paper you drew on.
Why is - x < 3 equivalent to x > - 3? Provide a convincing argument.
Answer:
-x<3 is the same as x>-3 because when you divide -x<3 by -1 on both sides it ends up as x>-3. (They're the same thing just one isn't simplified.)
