I think that the correct answer is true
Dina has a number cube that she uses for a game.
The number cube has the shape of a triangular pyramid, with 4 faces numbered 1 through 4. Dina rolls the number cube 100 times and records the results. She calculates the relative frequency of each outcome.
Outcome 1 2 3 4
Relative Frequency 0.23 0.24 0.26 0.27
Which statements about Dina's experiment are true?
Select each correct answer.
The relative frequencies in the table are reasonably close.
The theoretical probability of rolling an even number is 0.51.
The relative frequency of rolling an even number is 0.51.
The number cube is not likely to be fair.
Answer: the relative frequencies in the table are reasonably close.
Step-by-step explanation:
Theoretically relative frequency for all numbers are 0.25. If cube is cast
100 times there my be small fluctuations.
What is the formula for the volume of a trapezoidal prism?
Answer:
Ok so basically, the formula for Volume of a Trapezoidal Prism. If the prism length is L,trapezoid base width B, trapezoid top width A, and trapezoid height H, then the volume of the prism is given by the four-variable formula: V(L, B, A, H) = LH(A + B)/2. In other words, multiply together the length, height, and average of A and B.

Answer:
(a) 58 m²
Step-by-step explanation:
The area of a composite figure is found by dividing it into simpler shapes whose area formulas are known.
DivisionExtending the horizontal line to the left, we find it divides the shape into an upper rectangle with dimensions 2 m wide and 4 m high, and a lower rectangle with dimensions 10 m wide and 5 m high.
Rectangle areaThe area of a rectangle is the product of its dimensions:
A = LW . . . . . where L is the length and W is the width
The upper rectangle has an area of ...
A = (4 m)(2 m) = 8 m²
The lower rectangle has an area of ...
A = (10 m)(5 m) = 50 m²
Total areaThe area of the figure is the sum of the areas of the upper and lower rectangles:
A = (8 m²) +(50 m²) = 58 m²
The area of the figure is 58 square meters.
Additional comment
The area can also be figured by considering an enclosing rectangle 9 m high by 10 m wide, for an area of (9 m)(10 m) = 90 m². From this rectangle, a rectangle 4 m high and 8 m wide is removed from the upper right corner. The removed area is (4 m)(8 m) = 32 m². Then the remaining area is ...
90 m² -32 m² = 58 m² . . . . the area of the figure shown

Step-by-step explanation:
Answer:
18 1/12 ft = base length
Step-by-step explanation:
The area of a triangle of base b and height h is A = (1/2)(b)(h).
Since we want the measure of the base we solve this formula for b:
2A = (b)(h)
2A
and then divide both sides to obtain a formula for b: b = -----------
h
Substituting 217 ft^2 for A and 24 ft for h, we get:
b = 2*217 ft^2 / 24 ft = 18.0833.... ft
If the answer must contain a fraction, take the 18 and hold it and convert the remaining 0.08333... to a fraction. One way of doing this is to use a calculator. On my old TI calculator, I would type in 0.0833333333..
and then press the MATH key and then select Option 1: Decimal to fraction.
Doing this yields 1/12. You can check this result by dividing: 1/12 = 0.08333...
Then the final answer, converted from 18.08333... ft, is
18 1/12 ft = base length

In degrees Celsius, what is the temperature shown on the thermometer?
A) 12° c
B) 17° c
C) 63° c
D) 65° c
Answer:
63 degrees Celsius
Step-by-step explanation:
because the line in the middle of 60 and 70 is 65 but the red does not go to that line but it is in the 60s so therefore the answer is C)65degrees Celsuis
2x + 3y = 12
Identify the x- and y-intercept and graph the equation on the coordinate plane to the left. What is the y-value when x is 2? Answer these questions in the text box below.
Answer:
x int is (6,0). y int is (0,4) and y value when x is 2 is 8/3
Step-by-step explanation:
to solve these questions, we can simply plug everything in. The x intercept for Example, is where the y is equal to 0. So we can plug in 0 for y to get the x int, and vice versa for the y int. To find out the y value when x is two, plug in x as two
2 times 2 +3y=12
3y=8
y=8/3

x+47=90
x=43
----------------
y+x=90
put in 43 for x
y+43=90
y=47
Hope that helps :)
Answer:
X=43
y=47
Step-by-step explanation:
Well you have 47 degrees. Finding X first would be easier.
X and 47 are complementary (90 degreees) so you can subtract 47 from 90 and get “x” Which is 43.
Now for y.
Y and X is complementary also, which means since x is 43, 90-43 is 47. So y is 47.

A math class is having a discussion on how to determine if the expressions 4 x minus x + 5 and 8 minus 3 x minus 3 are equivalent using substitution. The class has suggested four different methods.
Which describes the correct method?
*Both expressions should be evaluated with one value. If the final values of the expressions are both positive, then the two expressions must be equivalent.
*Both expressions should be evaluated with one value. If the final values of the expressions are the same, then the two expressions must be equivalent.
*Both expressions should be evaluated with two different values. If for each substituted value, the final values of the expressions are positive, then the two expressions must be equivalent.
*Both expressions should be evaluated with two different values. If for each substituted value, the final values of the expressions are the same, then the two expressions must be equivalent.
Answer:
Both expressions should be evaluated with one value. If the final values of the expressions are the same, then the two expressions must be equivalent.

Which key correctly represents the information below?
A) 11 | 2 = 12
B) 1 | 2 = 12
C) 11 | 2 = 112
D) 11 | 2 = 13
Answer:
The correct answer is C) 11 | 2 = 112
Step-by-step explanation:
That is because that is how these kinds of stem and leaf plots work. You add the number on the left to each individual number of the right. For example, the numbers in row 11 are actually:
112, 112, 115, 118.
The reason why we have stem plots is that it removes the need to write the 11 at the beginning of the number and lets you interpret and analyze the data more easily.
Stemplots are also pretty annoying and useless, and something you'll basically never use, so don't worry if they don't make much sense :)

The figure is the net for a rectangular prism.
What is the surface area of the rectangular prism represented by the net?
please help
TωT
Answer:
544 cm^2
Step-by-step explanation:
You can see that the figure is made of 6 different rectangles, which would become the sides of the prism if it was 3D.
The top rectangle has a length of 16 cm and a width of 8 cm. 16 x 8 = 128 so this side has an area of 128 square cm
The one directly below that has the same length (16 cm) and a width of 6 cm. 16 x 6 = 96 so its area is 96 square cm
On either side of the previous one there is a 6 by 8 rectangle. 6 x 8 = 48. Remember, there are two sides with an area of 48 cm^2
Below that we have another 16 by 8 rectangle and then another 16 by 6 rectangle.
So your total surface area would be 128 + 96 + 48 +48 + 128 + 96
or 544 square cm

The circle graph shows how Lila spent her after-school time during the month of October.

If Lila spent a total of 50 hours on these activities in the month of October. How much time did she spent at Yoga?
Answer:
14 hours
Step-by-step explanation:
percent of a number
28% of 50
(OR, there is another way)
you could switch it and do 50% of 28, either way you get the same answer.
50% of 28 is 14.
***if there is any percent problem where it is something like 22% of 100 or 78% of 50, you can flip it to say 100% of 22 or 50% of 78.

help fast pls 7th grade
The probability that it will be watermelon flavored is -
P{E} = 1/5.
What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is a bag of jellybeans has 20 watermelons jellybeans, 45 sour apple jellybeans, 30 orange jellybeans and 5 cotton candy jellybeans.
We can write the probability as -
P{E} = (20)/(20 + 45 + 30 + 5)
P{E} = 20/100
P{E} = 1/5
Therefore, the probability that it will be watermelon flavored is -
P{E} = 1/5.
