A set of books sits on a shelf at a store. This line plot
shows the thickness of each book. Amelie buys the
thickest book on the shelf. Raj buys one of the thinnest
books on the shelf.
How much thicker is Amalie's book than Raj's book?
Answer:
The difference in their thickness is: [tex]2\frac{1}{2}[/tex]
Step-by-step explanation:
Given
The attached plot which represents thickness of books
Required
Difference in the thickness of Amalie's (A) and Raj's (R)
From the question, we understand that:
[tex]A \to[/tex] Thickest
[tex]R \to[/tex] One of the least
This implies that:
[tex]A = 4[/tex]
[tex]R = 1\frac{1}{2}[/tex]
The difference (d) is:
[tex]d = 4 - 1\frac{1}{2}[/tex]
[tex]d = 2\frac{1}{2}[/tex]
Answer:
2 1/2
Step-by-step explanation:
A soft drink machine outputs a mean of 2222 ounces per cup. The machine's output is normally distributed with a standard deviation of 44 ounces. What is the probability of filling a cup between 2525 and 3030 ounces? Round your answer to four decimal places.
Let X be the random variable for the output of the machine. Transform X to a standard normal random variable Z, using the rule
Z = (X - µ)/[tex]\sigma[/tex]
where µ and [tex]\sigma[/tex] are the mean and standard deviation of X.
Pr[25 < X < 30] = Pr[(25 - 22)/4 < (X - 22)/4 < (30 - 22)/4]
… = Pr[3/4 < Z < 2]
… = Pr[Z < 2] - Pr[Z < 3/4]
… ≈ 0.9773 - 0.7734
… ≈ 0.2039

Expected number of Daffodil when N = 150
First, we calculate the probability of having a Daffodil.
[tex]Pr = \frac{Daffodil}{Total}[/tex]
This gives:
[tex]Pr = \frac{14}{14+10+24+12}[/tex]
[tex]Pr = \frac{14}{60}[/tex]
Simplify
[tex]Pr = \frac{7}{30}[/tex]
When there are 150 flowers, the prediction of Daffodils is:
[tex]Prediction = Pr * N[/tex]
[tex]Prediction = \frac{7}{30} * 150[/tex]
[tex]Prediction = 7*5[/tex]
[tex]Prediction = 35[/tex]

You can find the volume of a sphere by multiplying the volume of a cylinder by 4/3: D. sphere.
How to calculate the volume of a sphere?Mathematically, the volume of a sphere can be calculated by using this formula:
V = 4/3 × πr³
Where:
V is the volume of a sphere.r is the radius of a sphere.Note: The volume of a cylinder is equal to πr² × r.
Thus, 4/3 × πr² × r = 4/3 × πr³ (Volume of a sphere).
How to calculate the volume of a cone?Mathematically, the volume of a cone is calculated by using this formula:
V = 1/3 × πr²h
Note: The volume of a cylinder is equal to πr²h.
Therefore, 1/3 × πr²h (volume of a cone).
How to calculate the volume of a pyramid?Mathematically, the volume of a pyramid is calculated by using this formula:

Philip deposited $50 in a savings account earning 10% interest, compounded annually.
To the nearest cent, how much will he have in 3 years?
Answer:
He will have $66.55 in 3 years.
Step-by-step explanation:
Given that,
Principal, P = $50
Rate of interest, R = 10%
We need to find the amount earned by him in 3 years. We know that, the final amount is given by :
[tex]A=P(1+\dfrac{r}{100})^T[/tex]
Put all the values,
[tex]A=50(1+\dfrac{10}{100})^3\\\\=50\times (\dfrac{11}{10})^3\\\\=\$66.55[/tex]

The length of each base of a trapezoid is shrunk to one-third its original length and the height of the trapezoid is tripled.
Lisa claims that the area of the new trapezoid is one-third the area of the original trapezoid.
Which expression best uses the dimensions of the new trapezoid to compare its area to the area of the original trapezoid in order to
determine if Lisa's claim is accurate?
A
lh + b) 3h
C С
3(02+)31
D
9514 1404 393
Answer:
A
Step-by-step explanation:
The formula for the area of the original trapezoid is ...
A = 1/2(b1 +b2)h
Using 1/3 the base length and 3 times the height, the area of the new trapezoid is ...
A = 1/2((1/3b1) +(1/3b2))(3h)
= (1/2)(1/3)(b1 +b2)(3h)
= 1/6(b1 +b2)3h . . . . . . . . matches choice A

(HELP FINAL EXAM) If two states are selected at random from a group of 40 states, determine the number of possible outcomes if the group of states are selected with replacement or without replacement.
Answer:
With replacement, there are 1600 possible outcomes.
Without replacement, there are 1560 possible outcomes.
Step-by-step explanation:
Chosen with replacement:
State is chosen, then put back in the group, then another state can be chosen. In both cases, there will be 40 possible outcomes, as the first taken state is placed back. So
40*40 = 1600
With replacement, there are 1600 possible outcomes.
Chosen without replacement:
State and chosen and is not replaced.
So, for the second state, there will be only 39 possible outcomes.
40*39 = 1560
Without replacement, there are 1560 possible outcomes.

Which of these equations has NO solution? A. 3 ( 2 x + 7 ) = 6 ( x + 4 ) − 3 B. 3 ( 6 x − 5 ) = 3 ( 6 x − 5 ) + x C. 8 ( x − 3 ) + 14 = 2 ( 4 x + 5 ) D. 13 x − 7 = 12 ( x − 1 ) + x + 5
Answer:
B ig
Step-by-step explanation:
A: 3(2x+7) = 6(X+4) - 3
<=> 6x+ 21 = 6x + 24 - 3 = 6x + 21
<=> 0 = 21 - 21 = 0
B: 3(6x-5)= 3(6x-5)+x
<=> 18x-15= 18x - 15 + x = 19x - 15
<=> 0 = x
C: 8(x-3) + 14= 2(4x+5)
<=> 8x - 24 + 14 = 8x - 10 = 8x + 10
<=> 0 = 0
D: 13x - 7 = 12( x - 1) +x + 5
<=> 13x - 7 = 12x -12 + x + 5 = 13x - 7
<=> 0 = 0
