Answer:
Step-by-step explanation:
Area of the rectangle inside the shape=
3*24=72
Area of the triangle inside the shape=
7*24/2=84
Area of the whole shape=
84+72=156
A figure shows a triangle drawn inside a trapezoid. The area of the triangle is 445 in², and the area of the trapezoid is 2225 in². A point on the figure is randomly selected, and its location is recorded.
After 150 trials, the randomly selected point was in the triangle 48 times.
How does the experimental probability of a randomly selected point being in the triangle compare to the theoretical probability of the event?
The experimental probability of the event is
Choose... 20, 30, or 32
and the theoretical probability of the event is
Choose...20, 30, or 32
Therefore, the experimental probability is
Choose... equal to, greater than, or less than.
the theoretical probability.
1) 70%
2) 62.5
3) GREATER THAN
Answer:
32%
20%
greater than
Step-by-step explanation:
The experimental probability of the event is 32% and the theoretical probability of the event is 20%. Therefore, the experimental probability is greater than the theoretical probability.
If you had a set of numerical data and you wanted to see what was typical for that set of data, what type of graph should you use? bar graph pictograph line plot line graph. I searched and did not find it
Hey there! :)
(1) I would say bar graph because on bar graphs, you can separate all the data into different bars and compare all the different data.
(2) For finding mean, you have to add all the numbers and divide by how many numbers there are.
0 + 1 + 2 + 3 + 4 + 5 + 6 = 21
There are 7 numbers.
21 ÷ 7 = 3
The mean is 3
Hope this helps :)

Find the value of x [tex]\frac{3}{2}x+5=14.[/tex]
Answer:
x=6
Step-by-step explanation:
bc 3/2 x 6 = 18/2 = 9 9+5=14
Answer: 6
Step-by-step explanation:
(3/2)x + 5 = 14
(3/2)x = 14 - 5
(3/2)x = 9
x = 9 / (3/2)
x = 9*2/3
x = 18/3
x = 6
36. How many 13 -card hands dealt from a standard deck will have exactly seven spades?
Answer:
6. The hand already has 3 clubs and cannot have any more clubs, so we have to choose 10 cards from the remaining 39 cards of 3 suits (spades, diamonds and hearts).
12. If four coins are flipped, find the probability of obtaining two heads and two tails.
Answer: 1/16 or 0.0625
Step-by-step explanation:
The probability of getting a heads is 1/2, and the probability of getting a tails is 1/2. To find the probability of getting 2 heads and 2 tails, multiply the probabilities of each event together. 1/2 * 1/2 * 1/2 * 1/2 = 1/16.

Hey need some help, I don't really under stand, I see that every one of them can be divided by 8 though. Thanks for the help!
Answer:
the answer should be 1:8 or 1/8 either way it tells you in the scale factor and in the fraction so remember we need to divide first the sculpture then the model since the sculpture has highest numbers and then the mode so as shown below here are the results of each one.
56/7=8
40/5=8
72/9=8
so the scale factor should be 1:8 since 8 units is 8 units in real life since and the fraction should be 1/8 so hopefully those are the correct answer and tell me if i am wrong so i can correct the answer to make it better.
Step-by-step explanation:
Please explain step-by-step. If you don't explain, don't even bother answering.
Answer:
45°
Step-by-step explanation:
From the diagram :
∠AOC = ∠AOB + ∠BOC96 = 9x - 75 + 8x - 6717x - 142 = 9617x = 238x = 238/17x = 14Finding ∠BOC :
∠BOC = 8x - 67∠BOC = 8(14) - 67∠BOC = 112 - 67∠BOC = 45°Answer:
Alrighty... i am happy that you would like an explanation.. that is truly admirable...
let's begin!!!
Step-by-step explanation:
We need to place everything into an equation to solve for x... after that we can substitute the value for x into the expression for m<BOC to get its value (i hope this isn't confusing... the math is easier though... trust me)
8X -67 +9X -75 = 96 Add 67 and 75 to both sides to isolate x
8X +9X = 238 --> 17X = 238
divide both sides by 17 to get x = 14
then subsitute x = 14 into the expression for m < BOC
you get 8(14)-67 = 45
therefore, the measure of <BOC is 45 degrees
I really hope this helps!!!!!

First Question: Screenshot the following image and attach a photo after you dilate by a scale factor of 2.
Second Question: Screenshot the following image and attach a photo after you dilate by a scale factor of 1/3.
Please help! If you help with this please do my other questions!! (They are very similar!)
Answer: See in the explanation, screenshot attached
Step-by-step explanation:
SQUARE QRTS
Step 1: Label all of the coordinates
Step 2: Find the coordinates of the points
Q: (-2, 1)
R: (2, 1)
T: (-2, -2)
S: (2, -2)
Step 3: Know what it means to dilate
To dilate is to make a shape bigger or smaller. For example, when it says to dilate by a scale factor of 2, you multiply each coordinate by 2 to get coordinate pairs that are twice the original amount (in this case you make it bigger). However, if it says to dilate by a scale factor of a fraction, for example 1/2, you'd multiply the coordinates by 1/2 and hence make it smaller (1/2 its size).
Step 4: Dilate by a scale factor of 2--multiply by 2
*x stands for the x coordinate, and y stands for the y coordinate*
Q: -2, 1
x: -2x2= -4
y: 1x2= 2
[Dilated] Q: -4, 2
R: 2, 1
x :2x2= 4
y: 1x2= 2
[Dilated] R: 4, 2
T: -2, -2
x: -2x2= -4
y: -2x2=-4
[Dilated] T: -4, -4
S: 2, -2
x: 2x2= 4
y: -2x2= -4
[Dilated] S: 4, -4
Step 5: Plot the new pairs
(See screenshot)
SQUARE ABCD
Step 1: Label all the coordinates
Step 2: Find the coordinate pairs of the points
A: -3, 3
B: 3, 3
C: 3, -3
D: -3, -3
Step 3: Remember what it means to dilate
(See 1st explanation)
Step 4: Dilate by a scale factor of 1/3
**Since 1/3 is a fraction, we are making the square smaller, or making it ⅓ of its original size. You will see that the numbers of the coordinates get smaller once you dilate them.**
A: -3, 3
x: -3x1/3= -1
y: 3x1/3= 1
[Dilated] A: -1, 1
B: 3, 3
x: 3x1/3 = 1
y: 3x1/3= 1
[Dilated] B; 1, 1
C: 3, -3
x: 3x1/3= 1
y: -3x1/3= -1
[Dilated] C: 1, -1
D: -3, -3
x: -3x1/3= -1
y: -3x1/3= -1
[Dilated] D: -1, -1
Step 5: Plot the new pairs
(see screenshot)
Hope this helps :))

Patricio deposits $500 in a savings account that pays 1.5% simple interest. He does not withdraw any money from the account, and he makes no other deposits.
How much money does Patricio have in the savings account after 5 yr?
Answer:
$537.50
Step-by-step explanation:
Initial Deposit = $500at a 1.5% interestSo . .
500.00 ×1.5 =7.5Then . .
7.5 is for 1 year so
7.5 × 5 = 37.5Then just add 37.50 to 500
Final outcome = $537.50Answer: He will have 3750 in 5 years.
Step-by-step explanation: You need to do 500x1.5x5. 500 dollars is the amount in the account. 1.5 is the interest. 5 is the amount of years.

On a DVD, information is stored on bumps that spiral around the disk. There are 73,000 ridges (with bumps) and 73,000 valleys (without bumps) across the diameter of the DVD. What is the diameter of the DVD in centimeters? Round your answer to the nearest whole number.
Answer:
I pretty sure it's 8cm.
Step-by-step explanation:
I multiplied 73,000 by 0.000074, which resulted in 5.402.
Then, I multiplied 73,000 by 0.000032, which resulted in 2.336.
I added the products together, which gave a sum of 7.738.
Then I rounded to the nearest whole number, which is 8, because the tenth in the decimal (.7) rounds up because it is >4.
