Answer:
2/5
Step-by-step explanation:
2/5=4/10
Answer:
2/5 is great because it's 40%
3/10 is 30%
so 2/5 is greater
Find the volume of the composite figure below.
Answer:
Volume of composit figure= 4834.14 cm^3
Step-by-step explanation:
here's your solution
=> Radius of hemisphere = 9 cm
==> volume of hemisphere = 2/3πr^3
==> volume of hemisphere = 2/3*22/7* 9^3
==> volume = 1526.04 cm^3
=> Radius of cylinder = 9 cm
=> Height of cylinder = 13 cm
==> volume of cylinder = πr^2h
==> volume of cylinder = 22/7*9^2*13
==> volume of cylinder = 3,308.1 cm^3
Volume of composit figure = 1526.04 + 3308.1
= 4834.14 cm^3
hope it helps

Given P(A) 0.3, P(B) = 0.43 and P(ANB) = 0.249, find the value of
P(AUB), rounding to the nearest thousandth, if necessary.
Answer:
0.481
Step-by-step explanation:
P(A U B) = P(A) + P(B) - P(A∩B)
= 0.3 + 0.43 - 0.249
= 0.73 - 0.249
= 0.481

The students in two 7th grade classes were asked, "How many text messages did they send over the past weekend?" The data was collected and a dot plot was created for each class. For what values do class A's distribution and class B's distribution overlap?
Answer:
2, 3, 4, and 5
Step-by-step explanation:
Class A and Class B's distributions overlap for the values of 2, 3, 4, and 5. This can be seen in the dot plot below since all of these values have inputs on both of the class' distributions. Values 0 and 1 are not included because they only have inputs for Class A, while values 6 and 7 are not included because they only have inputs for Class B. In order for the values to overlap they need to be included in both class distributions.
Answer:
2,3,4,5
Step-by-step explanation:
Class A and Class B distribution overlap at 2,3,4 and 5 because if you look at both graphs you can see how they both overlap each other.

Harriet bought 3 gal. 2qt, of a paint for her living room. She used 2 gal, 3 qt. How many paint is left over?
Answer:
3 qt
Step-by-step explanation:
Let's stick to one unit to facilitate things. I'm going to use quarts as the unit.
1 gal = 4 qt
Initial value = 3 gal 2 qt = 14 qt
Change = 2 gal 3 qt = 11 qt
14 qt - 11 qt = 3 qt

Which mapping diagram represents a function ? Would it be D?
Answer:
D
Step-by-step explanation:
Mathematically , for us to have a function, no 2 y values must have a single x value
Although, 2 x-values can have a single y value
The y values called the output values are listed on the right
The x values called the input values are listed on the left
So out of the options, with the given definition above, the one that represents a function is the option D
A. Their rates of change differ by 2. B. Their rates of change differ by 4. C. Function M has a greater rate of change than Function P. D. Function M and Function P have the same rate of change.
Answer:
(a) Their rates of change differ by 2
Step-by-step explanation:
Given
See attachment for functions M and P
Required
Determine what is true about the rates of M and P
First, we calculate the slope (i.e. rate) of both functions.
Slope is calculated as:
[tex]m = \frac{y_2 -y_1}{x_2 - x_1}[/tex]
From the table of M, we have:
[tex](x_1,y_1) = (-2,-9)[/tex]
[tex](x_2,y_2) = (2,11)[/tex]
So, the slope is:
[tex]m_M = \frac{11 --9}{2--2}[/tex]
[tex]m_M = \frac{20}{4}[/tex]
[tex]m_M = 5[/tex]
For function P, we have:
[tex]y = 7x + 9[/tex]
A function is represented as:
[tex]y = mx + b[/tex]
Where:
[tex]m = slope[/tex]
So, by comparison:
[tex]m_P = 7[/tex]
At this point, we have:
[tex]m_M = 5[/tex] --- Slope of M
[tex]m_P = 7[/tex] --- Slope of P
Only option (a) is true because both slopes differ by 2. i.e. 7 - 5 = 2
Other options are not true

Step-by-step explanation:
Find the measure of the angle between the vectors 〈6, –3, 1〉 and 〈8, 9, –11〉
A:90°
B:30°
C:84.8°
D:102.6°
Answer:
Option C.
Step-by-step explanation:
We know that for two vectors:
A = 〈a₁, a₂, a₃ 〉and B =〈b₁, b₂, b₃〉.
The dot product between A and B is:
A.B = IAI*IBI*cos(θ)
Where θ is the angle between the vectors.
And the dot product can be also written as:
A.B = a₁*b₁ + a₂*b₂ + a₃*b₃
With that, we can find the angle between our vectors.
In this case, the vectors are:
A = 〈6, –3, 1〉 and B = 〈8, 9, –11〉
The modules are:
IAI = √( 6^2 + (-3)^2 + 1^2) = 6.78
IBI = √( 8^2 + 9^2 + (-11)^2) = 16.31
And the dot product between A and B is:
A.B = 6*8 + (-3)*9 + 1*(-11) = 10
Then we have that:
10 = IAI*IBI*cos(θ) = ( 6.78)*(16.31)*cos(θ)
10/(6.78*16.31) = cos(θ)
Now remember the inverse cosine function, Acos(x), this function has the property:
Acos(cos(x)) = x
If we apply this to both sides, we get:
Acos(10/(6.78*16.31)) = Acos(cos(θ)) = θ = 84.8°
The correct option is C.

WHeres the questionnn???????
Step-by-step explanation:
Stephan has a piece of wood that measures 18 inches long and 12 inches wide. He wants to make a tray with sides 2 inches high. Maurice says that he can make a tray that has a base measuring 10 1/2 inches by 10 1/2 inches. Is he correct?
Answer:
he isn't
Step-by-step explanation:
The wood has dimensions of 18 x 12
If He wants the tray to have a height of 2, subtract 2 x 2 from both the length and the width
18 - 4 = 14
12 - 4 = 8
the highest possible dimensions of the tray can be 14 x 8
10 1/2 x 10 1/2 is greater than 14 x 8. so he is not correct

I have a 3 yellow m&m's, 5 blue m&m's, and 4 red m&m's. What is the probability if I choose a red and do not not put it back and then choose a yellow?
Answer:
8.3% probability
Step-by-step explanation:
(3) YELLOW ⇒ [tex]\frac{3}{12}[/tex] ⇒ 25%
(5) BLUE ⇒ [tex]\frac{5}{12}[/tex] ⇒ 41.6%
(4) RED ⇒ [tex]\frac{4}{12}[/tex] ⇒ 33.3%
║(12) IN TOTAL
[tex]\frac{4}{12}[/tex] ⋅ [tex]\frac{3}{12}[/tex] = [tex]\frac{1}{12}[/tex]
[tex]\frac{1}{12}[/tex] = 8.3%
PROBABILITY OF (1) RED, AND (1) YELLOW ⇒ 8.3% probability

Answer: $7,488
Step-by-step explanation:
For answer B:
The formula for the new balance would be A=P(1 + r)t
A = new balance
P = principal balance -> $900
r = rate (in decimal form)
t = time in years -> 8 years
To find the rate, convert 4% to decimal
4/100 = 0.04
A=P(1+ r)t
A=900(1+0.04)8
A=900(1.04)8
A=$7,488
