Answer:
1 7/8
Step-by-step explanation:
I think you need to times it like 2 1/2 x 3/4, first you make 2 1/2 into 5/2 then times it like this 5/2 x 3/4. the answer is 1 7/8
(Find the Probability Question)
Choose 2 girls from a class of 12 boys and 8 girls.
Step-by-step explanation:
what should be the question ?
how many different pairs of 2 girls can you pick out of 8 ?
what is the probability that a specific girl is in the picked pair ?
or is it : if you pick randomly 2 students from the class, what is the probability to have picked 2 girls ?
and there are more options.
but I assume the problem is the picking randomly 2 students.
so, it is 20 students (12 + 8). if we pick 1 student, we have a chance of 12/20 = 3/5 to pick a boy, and a chance of 8/20 = 2/5 to pick a girl.
in our experiment we pick 2 students in a row without returning the first pick into the main pool.
the probabilty for the first pick to be a girl is, as mentioned, 2/5 or 0.4.
for the second pick we have only 7 out of 19 choices to pick a girl. so, the probability to pick a girl now is 7/19.
the combination of both (non-overlapping) probabilities is done via multiplication, and the probabilty to pick 2 girls is :
2/5 × 7/19 = 2×7 / 5×19 = 14/95 = 0.147368421...

Answer:
91.1250 m^3
Step-by-step explanation:
The volume of a cube can be calculated if you know its side length. The formula is then volume cube = side3. This is simply the length of the side multiplied by itself two times.
Answer:
91.125
Step-by-step explanation:
The formula to find the volume of a cube is lwh. All the side lengths of a cube are equal. So in this case, 4.5 to the third power is 91.125.

Peter has a unique computer. The screen of the computer is a square and measures twelve inches. What is the area of the entire computer screen?
A. 144 in
B. 124 in
C. 54 in
D. 48 in
Answer:
A. 144 in
Step-by-step explanation:
Squares have congruent sides.
One side is 12 inches, so all of the other sides are 12 inches.
To find the area of a square, multiply width by height. The width is 12, and the height is also 12
12 * 12 = 144
144 in ^2

So well the live tutor isn't helping me well.. can one of you help me?
Answer:
The mean absolute deviation is 4
Step-by-step explanation:
The mean absolute deviation is a measure of how much a data set varies.
Step 1: Compute the mean
mean = the sum of all the terms / number of terms
mean = 94 + 86 + 95 + 99 + 88 + 90 / 6
= 552 / 6
= 92
The mean is 92
Step 2: Finding the absolute deviation
You would take each number in the data set and subtract it from the mean, take the absolute value. After you take the sum of the absolute data values
|data set #1 - mean| + |data set #2 - mean| + ... + |data set #6 - mean|
= |94 - 92| + |86 - 92| + |95 - 92| + |99 - 92| + |88 - 92| + |90 - 92|
= |2| + |- 6| + |3| + |7| + |- 4| + |- 2|
= 2 + 6 + 3 + 7 + 4 + 2
= 24
To find the mean absolute deviation you divided the sum by total number of terms...
24/6 = 4
The average (mean) is equal to the sum of all the data values divided by the count of values in the data set (which was step 1)

In the diagram of an apartment, each inch represents 6 feet. Which is the area of the apartment's balcony?
Answer:
72 square feet
Step-by-step explanation:
Since you already know the 2 inches, you just need to find out the other side, and by subtracting the longer side 6 inches, to the shorter side on the furthest side 5 inches, you get 1 inch. And since each inch represents 6 feet, the final equation would be 12 (2x6) x 6 (1x6). So the answer would be 72 square feet.

Heck did I do wrong!?!?! IXL sucks
Answer:
∠G, ∠HGI, ∠IGH
Step-by-step explanation:
» Concepts
To name an angle, you MUST include the vertex either in the middle or have it standing by itself. To clarify, you can either call this angle ∠G, ∠HGI, or ∠IGH because they all include the vertex, G, in the middle or by itself. You put ∠HIG, which is incorrect because the vertex is not I.
please help me. thanks.
[tex]~~~\text{Area of triangle} = \dfrac 12 \times \text{Base} \times \text{Height}\\\\\implies 10 = \dfrac 12 \times 5 \times w\\\\\implies w =\dfrac{20}5 \\\\\implies w = 4 ~cm[/tex]
Answer:
4cm
Step-by-step explanation:
» Concepts
The area of a triangle is how much space is in the triangle. The formula for the area of a triangle is [tex]\frac{1}{2} bh[/tex], where b = base and h = height.
» Application
We're given the area as 10 cm² and the base as 5 cm. Thus, we have to plug these values into the formula to solve for the height.
» Solution
[tex]10=\frac{1}{2} *5*h[/tex] [tex]10=\frac{5}{2}h[/tex] [tex]10*2/5=5/2(h)*2/5[/tex][tex]h=4[/tex]Is this polyhedron a prism, a pyramid, or neither? Explain how you know.

5) Solve for x and find both angle measurements -
Answer:
x = 30
(2x)° = 60°
x = 30°
Step-by-step explanation:
The two angles combined is a right angle, and a right angle is 90°, so we can put that into this equation:
2x + x = 90 which is the same as 3x = 90 because 2x + x = 3x
3x = 90
divide both sides by 3 so you can get x by itself
3x divided by 3 = x
90 divided by 3 = 30
you get x = 30
since x = 30, 2x is the same as 2 times 30, and that is 60.
