A. 6 was not multiplied by m
B. Incorrect sign was used for the first term
C. Incorrect sign was used for the second term
D. 6 was not multiplied by 3

Answers

Short Answer: D
Look at them one at a time

Choice A
The result of multiplying 6 and m together (which is what you are supposed to do is 6m). This step is correct.

Choice B
There are no minus signs anywhere, either outside or inside the brackets, B is incorrect. Minus signs cannot be manufactured out of thin air. You need a reason.

Choice C
Same as B.

D is the correct answer. Both sides of a plus or minus sign have to be multiplied by what is outside the brackets. The plus sign cannot be destroyed unless you started out with something like

6 ( 4m + 3m) which = 24m + 18m = 42m But you could have combined like terms in the beginning.
6 * 7m = 42m

A. 397.9 B. x < 397.9 and x > 402.1
C. x < 400.0 and x> 402.1
D. 400.0 > x < 402.1

Answers

from 0g to 494.7g are rejected as well as those heavier than 505.3grams.

You calculate this by subtracting and adding 5.3 to 500

Answer:

Option: B is the correct answer.

B. x < 397.9 and x > 402.1

Step-by-step explanation:

It is given that:

Each bag is advertised as weighing 400 grams.

Also, a bag must weigh within 2.1 grams in order to be accepted.

Hence, for the bag being accepted the weight must be no less than 2.1 gram from 400 gram and should be no more than 2.1 gram from 400 grams.

i.e. the weight of the bag must be such that:

400-2.1≤ x ≤ 400+2.1

i.e.

397.9 ≤ x ≤ 402.1

Hence, if the weight of the bag is less than 397.9 grams or is more than 402.1 grams then the bag will be rejected.

i.e. The range for the bag being rejected is: x<397.9 grams and x>402.1 grams.

triangle ABC is similar to Triangle XYZ.

YZ=118.8, Find XZ

triangle ABC is similar to Triangle XYZ.

AB=9.7, BC=9.6, AC=15.1

YZ=118.8, Find XZ

Answers

XZ = 186.8625.

Since the triangles are similar, the ratio of their angles is the same. This means the ratio of BC to YZ will be the same as the ratio of AC to XZ; using this to set up a proportion,

9.6/118.8 = 15.1/x

Cross multiply:
9.6*x = 118.8(15.1)
9.6x = 1793.88

Divide both sides by 9.6:
9.6x/9.6 = 1793.88/9.6
x = 186.8625

A motorboat covers the distance from one pier to the other pier in 4 hours and the way back in 5 hours. What is the speed of the boat in still water, if it covers 70 km with the current in 3.5 hours?
(its not 20 i tried)

Answers

r = speed in still water
r + c = speed with current
r - c = speed against current

3.5(r + c) = 70
r + c = 20
c = 20 - r

4(r + c) = distance from pier to pier
5(r - c) = distance from pier to pier
4(r + c) = 5(r - c)
4(r + 20 - r) = 5(r - 20 + r)
80 = 10r - 100
180 = 10r
18 = r
The speed in still water is 18 km/hour

The median and interquartile range of a set of data is shown. Write a set of data consisting of seven values for the pair of measures.
Median: 5 Interquartile Range: 5

Answers

If there are 7 data points (an odd number), then the median, 5, is right in the middle of the 7 points: x y z 5 q r s.

If the IQR is 5, we then know that the difference between y and r is 5.

Let's find the 1st and 3rd quartiles. Focusing on the 1st 3 numbers, we see that the 1st quadrant is y; focusing on the last 3 numbers, we see that the 3rd quadrant is r. The IQR is r-y = 5. Just supposing that y were 4, r would be 9:

x 4 y 5 q 9 s

We could arbitrarily let x = 3, y = 4, q = 5 and s = 9: 3 4 4 5 5 9 9.

We must check this!
What is the median? Since there are 7 numbers here, we take the middle number (5) as the median. This agrees with the problem statement.
Next, we find Q1 and Q3. Q1 is the number between 3 and the 2nd 4, and is 4. Q3 is 4+5, or 9, because the IQR is 5. This agrees with the problem statement.

The equation yˆ=0.09x+55.64 models a person's height, in inches, where x is the weight of the person in pounds. According to the regression equation, what is the approximate height of a person that weighs 160 pounds?

Answers

y = 0.09*x + 55.64
y = 0.09*160 + 55.64 <<--- replace x with 160
y = 14.4 + 55.64
y = 70.04

The person who weighs 160 pounds is predicted to be about 70.04 inches tall

Note: 70.04 inches = 5 ft, 10.04 inches (so roughly 5'10")

Answer:

Height is 70.04 inches.

Step-by-step explanation:

Given that the equation

[tex]yˆ=0.09x+55.64[/tex] models a person's height, in inches, where x is the weight of the person in pounds.

We have to find out the approximate height of the person that weighs 160 pounds

Algebraically we have to find y for x = 160

Substitute for y in the given equation.

[tex]y=0.09(160)+55.64\\y=70.04"[/tex]

A small Learning Center holds 24 less students than the larger Learning Center. Together the learning centers hold seventy-two students. How many students does each Learning Center hold?

Answers

s=small
L=Large

72=(L-24)+s
48=L+s
By this point, the “-24” no longer affects the equation. L=s for the purpose of division.
48/2
24=s
Now we know s=24.
The “-24” is now important in finding the value of L. We find the inverse of “-24”, +24.
s+24=48

s= 24 students
L= 48 students

Final answer:

The larger Learning Center can hold 48 students and the smaller Learning Center can hold 24 students.

Explanation:

The key to solving this problem is to first express it as two linear equations. Let's denote the number of students the small Learning Center holds as S and the number of students the larger Learning Center holds as L.

The problem provides us with two facts:

The small Learning Center holds 24 less students than the larger one, we can express this as: S = L - 24.Together, both Learning Centers hold seventy-two students, so we can express this as: S + L = 72.

Now, we can solve these two equations simultaneously.

Substitute S from the first equation into the second: (L - 24) + L = 72, simplify to: 2L = 96

Thus, L = 48. This means the larger Learning Center can hold 48 students. Substitute L=48 into our first equation to find S: S = 48 - 24 = 24. So, the small Learning Center can hold 24 students.

what number must you add to complete the square? x2-20x=17
A. 100
B. -10
C.-100
D. 10

Answers

Answer:

The number is 100

A is correct

Step-by-step explanation:

Given: [tex]x^2-20x=17[/tex]

We need to make completing square at left side.

Rule: We add a number " take half of the coefficient of x and then square it"

Coefficient of x = 20

Half of 20 = 10

Square of 10 = 100

So, we will add 100 both sides make completing square.

Now we make completing square to add 100

[tex]x^2-20x=17[/tex]

Add 100 both sides

[tex]x^2-20x+100=17+100[/tex]

Now we will factor left side perfect square

[tex]a^2-2ab+b^2=(a-b)^2[/tex]

[tex](x-10)^2=117[/tex]

[tex](x-10)^2[/tex] is completing square or perfect square.

Hence, The number is 100

Of the 3,558 people impaired drivers killed in 2009 (not counting the drivers themselves) death were preventable

Answers

Final answer:

The preventable nature of deaths caused by impaired driving, emphasizing the impact of alcohol and other risky behaviors on driving safety.

Explanation:

Each day in the United States, over 8 people are killed and 1,161 injured in crashes reported to involve a distracted driver, highlighting a significant public health concern. There is a noted problem with young drivers getting into serious automobile accidents, contributing to many preventable deaths.

It has been estimated that 35 percent of all U.S. early deaths in 2000 could have been avoided by changing just three behaviors, with alcohol being a significant contributing factor to risky behavior on the roads.

In 2014, alcohol-impaired driving fatalities accounted for 9,967 deaths, which is 31% of overall driving fatalities, underscoring the critical need for improved driving safety measures and individual behavior changes to reduce these numbers.

Determine which function has the greatest rate of change over the interval [0, 2].

Answers

Remember that the average rate of change of a function over an interval is the slope of the straight line connecting the end points of the interval. To find those slopes, we are going to use the slope formula: [tex]m= \frac{y_{2}-y_{1}}{x_2-x_1} [/tex]

Rate of change of [tex]a[/tex]:
From the graph we can infer that the end points are (0,1) and (2,4). So lets use our slope formula to find the rate of change of [tex]a[/tex]:
[tex]m= \frac{y_{2}-y_{1}}{x_2-x_1} [/tex]
[tex]m= \frac{4-1}{2-0} [/tex]
[tex]m= \frac{3}{2} [/tex]
[tex]m=1.5[/tex]
The average rate of change of the function [tex]a[/tex] over the interval [0,2] is 1.5

Rate of change of [tex]b[/tex]:
Here the end points are (0,0) and (2,2)
[tex]m= \frac{2-0}{2-0}[/tex]
[tex]m= \frac{2}{2} [/tex]
[tex]m=1[/tex]
The average rate of change of the function [tex]b[/tex] over the interval [0,2] is 1

Rate of change of [tex]c[/tex]:
Here the end points are (0,-1) and (2,0)
[tex]m= \frac{0-(-1)}{2-0}[/tex]
[tex]m= \frac{1}{2} [/tex]
[tex]m=0.5[/tex]
The average rate of change of the function [tex]c[/tex] over the interval [0,2] is 0.5

Rate of change of [tex]d[/tex]:
Here the end points are (0,0.5) and (2,2.5)
[tex]m= \frac{2.5-0.5}{2-0} [/tex]
[tex]m= \frac{2}{2} [/tex]
[tex]m=1[/tex]
The average rate of change of the function [tex]d[/tex] over the interval [0,2] is 1

We can conclude that the function that has the greatest rate of change over the interval [0, 2] is the function a.
