The commute time to work in the U.S. Has a bell shaped distribution with a population mean of 24.4 minutes and a population standard deviation of 6.5 minutes. What proportion of the population has a commute time: a) between 11.4 minutes and 37.4 minutes? (1 pt) b) less than 11.4 minutes? (1 pt) c) greater than 37.4 minutes? (1 pt)
Answer:
1. 0.9544
2. 0.0228
3. 0.0228
Step-by-step explanation:
The computation is shown below;
As we know that
At Normal distribution
[tex]P(X < A) = P(Z < \frac{(A - mean)}{standard deviation})[/tex]
As per the question, the data provided is as follows
Mean = 24.4 minutes
Standard deviation = 6.5 minutes
Based on the above information
P(11.4 < X < 37.4) = P(X < 37.4) - P(X < 11.4)
= P(Z < (37.4 - 24.4) ÷ 6.5) - P(Z < (11.4 - 24.4) ÷ 6.5)
= P(Z < 2) - P(Z < -2)
= 0.9772 - 0.0228
= 0.9544
2. P(X < 11.4) = 0.0228
3. P(X ≥ 37.4) = 1 - P(X < 37.4)
= 1 - 0.9772
= 0.0228

4/5 x (-2/9) (as a fraction) (simplified)
Answer:
[tex]-\frac{8}{45}[/tex]
Step-by-step explanation:
So when multiplying fractions, you would multiply the numerator of the first fraction by the numerator of the second fraction and make that product the numerator of the resulting fraction and multiply the denominator of the first fraction by the denominator of the second fraction and make that product the denominator of the resulting fraction. In other words:
[tex]\frac{a}{b}*\frac{c}{d}=\frac{a*c}{b*d}[/tex]
So lets multiply the two fraction together:
[tex]\frac{4}{5}*(-\frac{2}{9})==-(\frac{4*2}{5*9})=-\frac{8}{45}[/tex]
So now we found the product. Now we have to try to try to simplify the fraction. To do this, we must find the GCF of the numerator, 8, and the denominator, 45.
Factors of 8: 1, 2, 4, 8
Factors of 45, 1, 3, 5, 9, 15, 45
As we can see, the GCF of 8 and 45 are 1. The fraction is simplified as much as possible.

Using the information that
5.2 x 67 = 348.4
write down the value of
a) 52 x 67
b) 5.2 x 6.7
c) 348.4 - 52
Answer:
Below in bold.
Step-by-step explanation:
a) 52 = 5.2 * 10 so the result is 348.4 * 10 = 3484.
b) 6.7 is a tenth of 67 so the result is 348.4 / 10 = 34.84.
c) 348.4 - 52 = 296.4.

5. Danny is selling cornhole boards to raise money for a local charity. He rents a booth at the state fair for $250. He sells the boards for $45. It costs him $20 to make each board. How many boards must Danny sell to break even for the cost of renting a booth? *
Answer:
10 boards
Step-by-step explanation:
$450-$250=$200. $20 * 10 boards = $200. $200-$200=0.

Solve the two-step equation.Analyze the solution shown.
1. –|–x| = 7: given
2. |–x| = –7: multiplication property of equality
3. –x = 7 or –x = –7: definition of absolute value
4. x = –7 or x = 7: multiplication property of equality
5. Check: –|–(–7)| = 7, –7 ≠ 7
–|–7| = 7, 7 = 7
Negative times negative is positive.
Determine the flaws in the solution.
The multiplication property of equality in Step 2 should result in |x| = 7.
The definition of absolute value is applied incorrectly. There is no solution.
The reason in Step 4 should be the addition property of equality.
The multiplication property of equality in Step 4 should result in only x = 7.
In evaluating the solutions, the absolute value should be simplified first to get a positive value.
Answer:n evaluating the solutions, the absolute value should be simplified first to get a positive value.
The definition of absolute value is applied incorrectly. There is no solution.

Answer:
you end up with 75 divided by 3.
Step-by-step explanation:
75 divided by 3 - 8 + 8
add 60 and 15
3 - 2(4) + 2^3
multiply -2 by 4
3 - 8 + 2^3
multiply 2 by itself 3 times
3 - 8 + 8 (which gives you 3 again)
and you get 75 divided by 3

The proof that m∠2 = m∠3 in the two column proof table is; shown in the various steps and concludes with subtraction property of equality
How to complete the two column proof?We are given;
∠1 and ∠2 are supplements
∠3 and ∠4 are supplements
∠1 ≅ ∠4
Now, since ∠1 and ∠2 are supplements, it means that;
m∠1 + m∠2 = 180° because of the definition of supplementary angles.
Since ∠3 and ∠4 are supplements, it means that;
m∠3 + m∠4 = 180° because of the definition of supplementary angles.
We are told that ∠1 ≅ ∠4
Thus;
m∠1 + m∠2 = m∠3 + m∠1 (Substitution property of equality)
Finally, we can reduce to get;
m∠2 = m∠3 (subtraction property of equality)

Solve for w: -4u-w = u+6w
Answer:
A
Step-by-step explanation:
-4u - w = u + 6w
-4u = u + 7w (Add w to both sides)
-5u = 7w (Subtract u from both sides)
w = [tex]-\frac{5u}{7}[/tex] (Divide both sides by 7)
Answer:
w=(-5u)/7
Step-by-step explanation:
-4u-w=u+6w
Combine like terms
-4u-u=6w+w
-5u=7w
Divide both sides by 7 to cancel it out on the right side and isolate w
(-5u)/7=(7w)/7
(-5u)/7=w
w=(-5u)/7

7/9 greater or less than 0.7777
We can conclude that 7/9 is equal to 0.777.
What mathematical operations are exactly?Calculating a value while utilizing operands and a math operator is known as a mathematical "operation."The supplied operands or numbers must follow specific guidelines that are associated with the symbol for the math operator.Addition, subtraction, multiplication, division, exponentiation, and modulus are all operations carried out by arithmetic operators.So, we need to solve 7/9 to know if it is greater, less, or equal to 0.777.
7/9 = 0.7777So, 7/9 is equal to 0.777(Refer to the image attached below for calculation)
Therefore, we can conclude that 7/9 is equal to 0.777.

While sitting in class you overheard one of your classmates say, "This equation has infinite solutions, because when I put it in Desmos it gave me parallel lines so I know it makes a conditional equation." Realizing that the student is incorrect, what would you say to help your classmate get their facts straight?
Answer:
See below
Step-by-step explanation:
The systems of linear equations represent two lines.
There are 3 possible outcomes with two lines on the plane.
1. Lines intersect
In this case there is one solution, which is the point of intersection.2. Lines are parallel
In this case the lines never intersect, so there is no solution2. Lines are same
In this case the lines overlap, so there are infinitely many solutions.In how many ways 5 people can sit on 5 chairs on a podium

Answer:
(-4, 0)
Step-by-step explanation:
You can plot the points and choose the one that looks like it's in the right place for a reflection across the line. The line of reflection will be the perpendicular bisector of the segment between R and its image.
In the attached plot, we see that the third choice (point C) is the desired image of R.
