Answer:
1,206
Step-by-step explanation:
Since we'll have to deal with cubic inches (with the ball volume), we should also calculate the volume of the car in cubic inches.
We are told the car is a rectangular prism measuring 10ft x 5 ft x 3 ft.
So, in inches (12 inches/foot), we have: 120 in x 60 in x 36 in = 259,200 cu inches.
The ball is a sphere with a radius of 3 inches.
Real volume of the ball: V = (4/3) π r³
V = (4/3) π 3³ = 36 π = 113.1 cu inches
But of course, balls don't fit perfectly one next to another, like cubes, so we have to take into account the loss... the question tells us to use a factor of 190%.
So, the packing volume of a ball is 190% its real volume:
PV = 190% * 113.1 = 214.9 cu inches
Now, how many times does that fit inside the car?
259,200 / 214.9 = 1,206.14
Let's round it to 1,206, which is a possible answer.

Tariq designed the pool shown. The owner of the pool has one square cover to use. Find the area of the space that needs to be covered. (The four corners are squares.)
The area that needs to be covered is
___ ft2.
Answers
Step 1: Find the total area. Since it is a square all the sides are 12 ft so multiply 12 by 12
12 x 12 = 144
^^^This is the total area including the area around the pool. We just need the are of the pool
Step 2: Outside of the pool there are four little 2 ft by 2 ft squares that aren't part of pool, and therefore won't need to be covered. The area of these 2 ft by 2 ft square is 4ft (2 times 2 is 4). Since there are 4 of these squares we multiply 4 by 4 to get 16. This means that 16 ft of the 144 ft we found previously are not part of the pool and we must subtract 16 from 144 to get the total pool area
144 - 16 = 128
This means that the area of the pool is 128 ft

This data can be written as
1.5, 1.5, 2, 2.5, 2.5, 2.5, 3, 3.5, 3.5, 4
The mean of the data is
[tex]Mean=\frac{\sum x}{n}=\frac{1.5+1.5+2+2.5+2.5+2.5+3+3.5+3.5+4}{10}=2.65[/tex]
The number of terms is 10 which is an even number. So, the median of the data is
[tex]Median=\frac{(\frac{n}{2})th+(\frac{n}{2}+1)th}{2}=\frac{5th+6th}{2}=\frac{2.5+2.5}{2}=2.5[/tex]
If next student presents a monologue that is about 0.5 minutes long, then the new data is
0.5, 1.5, 1.5, 2, 2.5, 2.5, 2.5, 3, 3.5, 3.5, 4
The mean of the new data is
[tex]Mean=\frac{\sum x}{n}=\frac{0.5+1.5+1.5+2+2.5+2.5+2.5+3+3.5+3.5+4}{11}=2.4545..\approx 2.45[/tex]
The number of terms is 11 which is an odd number. So, the median of the new data is
[tex]Median=(\frac{n+1}{2})th=6th=2.5[/tex]
Median of given data and new data is same but the mean of new data is less than the mean of original data. It means the mean will decrease.
Therefore the correct option is B.

To simplify a complex fraction, multiply both the numerator and the denominator by the same factor to eliminate fraction in the denominator, cancel common factors and follow rules of algebra to maintain equality.
Explanation:To evaluate and simplify a complex fraction, we can use a strategy that involves multiplying the numerator and denominator by the same factor. For example, if our complex fraction had a denominator of 1/2, we could multiply both the numerator and the denominator by 2 to eliminate the fraction in the denominator. This approach ensures the units or variables cancel out where appropriate, leaving us with a simpler expression. When working with fractions, common factors can be identified and cancelled to simplify the fraction further. Always remember that fractions represent division, so when simplifying, divide the digit term of the numerator by that of the denominator and subtract the exponentials accordingly. This process is governed by the rules of algebra, maintaining the equality of the expression.

Answers
Answer:
3
Step-by-step explanation:
The mean absolute deviation of the data set is approximately 3.09.
The mean absolute deviation (MAD) is a measure of variability that indicates the average distance between observations in a data set and their mean.
To calculate the MAD, you first need to find the mean of the data set. In this case, the mean is 31.375.
Then, you calculate the absolute deviation of each data point from the mean. For example, the absolute deviation of the first data point (21) is 10.375 (|21 - 31.375|).
Once you have calculated the absolute deviation of each data point, you find the average of those absolute deviations. This is the mean absolute deviation.
In the example data set, the mean absolute deviation is approximately 3.
Find the mean of the data set: (21 + 22 + 24 + 26 + 27 + 28 + 20 + 30) / 8 = 31.375
Calculate the absolute deviation of each data point from the mean. For example, the absolute deviation of the first data point (21) is 10.375 (|21 - 31.375|).
Add up the absolute deviations of all the data points. In this case, the sum of the absolute deviations is 24.75.
Divide the sum of the absolute deviations by the number of data points to find the mean absolute deviation. In this case, the mean absolute deviation is 24.75 / 8 = 3.09375.
Therefore, the mean absolute deviation of the data set is approximately 3.09.
The complete question is:What is the mean absolute deviation of the data set?

Find the inverse of the following function.
Answers
For this case we must find the inverse of the following function:
[tex]f (x) = \sqrt [3] {x + 12}[/tex]
For this, we follow the steps below:
Replace f (x) with y:
[tex]y = \sqrt [3] {x + 12}[/tex]
We exchange the variables:
[tex]x = \sqrt [3] {y + 12}[/tex]
We solve the equation for "and":
[tex]\sqrt [3] {y + 12} = x[/tex]
We raise both sides of the equation to the cube to eliminate the root:
[tex](\sqrt [3] {y + 12}) = x ^ 3\\y + 12 = x ^ 3[/tex]
We subtract 12 on both sides of the equation:
[tex]y = x ^ 3-12[/tex]
Thus, the inverse function is:
[tex]f ^ {- 1} = x ^ 3-12[/tex]
Answer:
Option B
Option: B is the correct answer.
B. [tex]f^{-1}(x)=x^3-12[/tex]
Step-by-step explanation:The inverse function f(x) is calculated in the following steps.
Put f(x)=yInterchange x and y in the equation.Now, solve for y.The function f(x) is given by:
[tex]f(x)=\sqrt[3]{x+12}[/tex]
Now, we keep:
[tex]f(x)=y\\\\i.e.\\\\y=\sqrt[3]{x+12}[/tex]
Now, we interchange x and y
[tex]x=\sqrt[3]{y+12}[/tex]
Now, on taking cube on both side of the equation we have:
[tex]y+12=x^3\\\\i.e.\\\\y=x^3-12[/tex]
i.e.
[tex]f^{-1}(x)=x^3-12[/tex]
A drawer contains 4 black socks, 3 white socks, and 2 red socks. One sock is drawn from the drawer and kept. The second sock is drawn from the drawer. What is the probability that they are both white?
Answers
The probability that they are both white if the first sock is kept and second is drawn will be 8.33%.

A drawer contains 4 black socks, 3 white socks, and 2 red socks.
One sock is drawn from the drawer and kept.
The second sock is drawn from the drawer.
The total number of the event will be
Total event = 9
Then the probability that they are both white will be

The probability of drawing two white socks from the drawer is 2/27.
Explanation:To find the probability that both socks drawn are white, we need to find the probability of drawing a white sock on the first draw and then drawing another white sock on the second draw.
There are a total of 9 socks in the drawer (4 black, 3 white, and 2 red).
The probability of drawing a white sock on the first draw is 3/9 (3 white socks out of 9 total socks).
After replacing the first sock, the total number of socks remains the same, but the number of white socks decreases to 2. So the probability of drawing a white sock on the second draw is 2/9.
Now, to find the probability of both events happening, we multiply the probabilities together: P(First white sock) * P(Second white sock) = (3/9) * (2/9) = 6/81 = 2/27.
Therefore, the probability that both socks drawn are white is 2/27.

The graph in the attached figure
Step-by-step explanation:
Part 1) Solve the system by elimination
Let
x----> the cost per can of grape juice
y----> the cost per can of apple juice
we know that
[tex]6x+4y=13.10[/tex] -----> equation A
[tex]4x+6y=13.10+0.60[/tex]
[tex]4x+6y=13.70[/tex] -----> equation B
Solve the system by elimination
Multiply the equation A by -6 both sides
[tex]-36x-24y=-78.6[/tex] -------> equation C
Multiply the equation B by 4 both sides
[tex]16x+24y=54.8[/tex] -------> equation D
Adds equation C and equation D
[tex]-36x-24y=-78.6\\16x+24y=54.8\\----------\\-36x+16x=-78.6+54.5\\-20x=-23.8\\x=1.19[/tex]
Substitute the value of x in the equation A
[tex]6(1.19)+4y=13.10[/tex]
[tex]4y=5.96[/tex]
[tex]y=1.49[/tex]
therefore
The cost per can of grape juice is [tex]\$1.19[/tex]
The cost per can of apple juice is [tex]\$1.49[/tex]
Part 2) Solve the system by substitution
Let
x----> the cost per can of grape juice
y----> the cost per can of apple juice
we know that
[tex]6x+4y=13.10[/tex]
[tex]4y=-6x+13.10[/tex]
[tex]y=-1.5x+3.275[/tex] -----> equation A
[tex]4x+6y=13.10+0.60[/tex]
[tex]4x+6y=13.70[/tex]
[tex]6y=-4x+13.70[/tex]
[tex]y=-(4/6)x+13.70/6[/tex]
[tex]y=--0.67x+2.28[/tex] -----> equation B
Substitute equation B in equation A and solve for x
[tex]-0.67x+2.28=-1.5x+3.275[/tex]
[tex]1.5x-0.67x=3.275-2.28[/tex]
[tex]0.83x=0.995[/tex]
[tex]x=1.19[/tex]
Find the value of y
Substitute the value of x in the equation A
[tex]y=-1.5(1.19)+3.275=1.49[/tex]
therefore
The cost per can of grape juice is [tex]\$1.19[/tex]
The cost per can of apple juice is [tex]\$1.49[/tex]
Part 3) Solve the system by graphing
we have
[tex]y=-1.5x+3.275[/tex] -----> equation A
[tex]y=-(4/6)x+13.70/6[/tex] -----> equation B
Remember that
The solution of the system of equations is equal to the intersection point both lines
The solution is the point [tex](1.19,1.49)[/tex]
see the attached figure
therefore
The cost per can of grape juice is [tex]\$1.19[/tex]
The cost per can of apple juice is [tex]\$1.49[/tex]

Answer:
Fourth option
Step-by-step explanation:
An m×n matrix is a matrix with m rows (horizontal lines) and n columns (vertical lines).
By definition, the multiplication of two matrices [tex]m_1[/tex]×[tex]n_1[/tex] and [tex]m_2[/tex]×[tex]n_2[/tex] can be done only if:
[tex]n_1 = m_2[/tex]
In the first option:
[tex]n_1 = 2\\m_2 = 1[/tex]
In the second option
[tex]n_1 = 1\\m_2 = 2[/tex]
In the third option
[tex]n_1 = 2\\m_2 = 1[/tex]
In the fourth option
[tex]n_1 = 1\\m_2 = 1[/tex]
[tex]n_1 = m_2[/tex] Multiplication can be done
Which is the equivalent of 6 14’ 48” written in decimal form ?
Answers
Answer:
Option A. 6.247°
Step-by-step explanation:
we know that
1°=60'
1'=60"
we have
6° 14' 48"
Convert to decimal form
Convert seconds to minutes
48"=48/60=0.8'
so
6° 14' 48"=6° + 14' +0.8'=6° 14.8'
Convert minutes to degrees
14.8'=14.8/60=0.247°
so
6° 14.8' =6° + 0.247°=6.247°
Answer:
6.247
