.
m<1 = 40 - 4x; and
m<2 = 50 - 8x.
A. 1.5
B. 2
C. 30
D. 2.5
Explanation:
If line r and line s are parallel, then the two angles marked must be congruent. Refer to the corresponding angles theorem for more details.
This means we'll set the angles equal to one another and solve for x.
angle1 = angle2
40-4x = 50-8x
-4x+8x = 50-40
4x = 10
x = 10/4

Which expression shows 35+ 15 written as a product of two factors?
7(5+2)
5(6 + 3)
5(7 + 3)
7(5+3)?
Answer:
5(7+3)
Step-by-step explanation:
Because 7+3=10 and 10x5=50. And also 35+15=50 so 50 and 50
Hey there!
35 + 15
= 50
Option A.
7(5 + 2)
= 7(5) + 7(2)
= 35 + 14
= 49
49 ≠ 50
Option B.
5(6 + 3)
= 5(6) + 5(3)
= 30 + 15
= 45
45 ≠ 50
Option C.
5(7 + 3)
= 5(7) + 5(3)
= 35 + 15
= 50
50 = 50
Option D.
7(5 + 3)
= 7(5) + 7(3)
= 35 + 21
= 56
56 ≠ 50
Therefore, the answer should be:
Option C. 5(7 + 3)
Good luck on your assignment & enjoy your day!

Suppose the commute times for employees of a large company follow a
normal distribution. If the mean time is 18 minutes and the standard
deviation is 5 minutes, 95% of the employees will have a travel time within
which range?
A. 13.25 minutes to 22.75 minutes
B. 8 minutes to 28 minutes
Using the Empirical Rule, it is found that 95% of the employees will have a travel time within the following range:
B. 8 minutes to 28 minutes.
What does the Empirical Rule state?It states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.Considering that the mean time is 18 minutes and the standard deviation is 5 minutes, the the bounds of the 95% range are given by:
18 - 2 x 5 = 8 minutes.18 + 2 x 5 = 28 minutes.Hence option B is correct.

NO LINKS!! Write the equation of the trigonometric graph. Try fractional values or π for the box next to x.
Answer:
y = 1·cos(π/3·x) +3
Step-by-step explanation:
The general form of the trig equation will be ...
y = (amplitude)·cos(2π/(period)·x) +(midline shift)
__
midlineYou have already determined correctly that the midline shift is 3 units.
amplitudeThe amplitude is the difference between the peak value (4) and the midline, so is ...
amplitude = peak - midline = 4 -3 = 1
periodThe period is the horizontal distance between corresponding parts of the graph. Here, the distance between peak values is 6 units, so the period is 6. That means the argument of the cosine function is ...
(2π)/6·x = (π/3)·x
__
The function you are looking for is ...
[tex]y=1\cdot\cos\left(\dfrac{\pi}{3}x\right)+3[/tex]
Answer:
[tex]y=\boxed{1}\: \cos(\:\boxed{1}\:x)+\boxed{3}[/tex]
Step-by-step explanation:
General form of cos periodic function:
y = A cos(B(x + C)) + D
where:
A = Amplitude (height from the center line to the peak or trough)2π/B = Period (horizontal distance between one peak and the next)C = (horizontal) Phase ShiftD = Vertical ShiftParent function → y = cos(x)
The parent function y = cos(x) has a center line at y = 0.
The center line of the new function is at y = 3, so the parent function has been shifted vertically by 3 units. Therefore, D = 3:
⇒ y = A cos(B(x + C)) + 3
The amplitude of the parent function is 1.
The amplitude of the new function is also 1. Therefore, A = 1:
⇒ y = 1 cos(B(x + C)) + 3
The parent function has a peak at x = 0.
The new function has a peak at x = 0. Therefore there has been no horizontal phase shift, so C = 0:
⇒ y = 1 cos(B(x + 0)) + 3
⇒ y = 1 cos(Bx) + 3
Finally, from inspection of the curve, the period appears to be 2π (6.28)
2π/B = 2π so B = 1
⇒ y = 1 cos(1x) + 3
Please see attached graph for reference.
The parent function is shown in blue.The dotted line is shown in grey.The new function is shown in black.Which data set could be represented by the box plot shown below?
Answer:
(D)
Step-by-step explanation:
The box plot is a visual representation of the 5-number summary of the data. It shows the extremes, the quartiles and the median.
__
Each data set has 11 elements, sorted into increasing order.
extremesThe first and last elements of the data set correspond to the ends of the whiskers, so you are looking for a set that ranges from 3 to 18. (This eliminates choice B.)
medianThe median will be the middle element, the 6th from either end. The vertical line in the box identifies its value as 10. (This eliminates choice A.)
quartilesThe first quartile is the middle element of the bottom half of the data set (what remains after the median and above elements are removed). There are 5 elements in the bottom half, so the first quartile is the 3rd one. It is signified by the left end of the box in the box plot. Its value is 7. (This eliminates choice C.)
Similarly, the third quartile is the 3rd element from the right end of the data set. The value 13 in choice D matches the right end of the box in the box plot.
The box plot represents the data set in Choice D.

A box of chocolates contains 18 chocolate squares. 10 of the squares are milk chocolate. 5 are dark chocolate and 3 are white chocolate if christina randomly chooses a chocolate out of the box, what is the probability of her choosing a white chocolate square
Answer:
Either %16.67 or %17 if rounded
Step-by-step explanation:.
An easy way to do this is convert the probability from a fraction into a percent. We can do this by taking the total number of chocolate squares (18) and using this as a denominator. Then take the number of white chocolate squares (3) and using this as our numerator. This give us a fraction of 3/18. Now to turn this into a percent, we need to find what you need to multiply 18 by to get 100. We can do this easily by deviding 100 by 18. This is a long decimal so i'll keep it in fraction form (100/18). Now you just have to multiply 3 by (100/18). This is about 16.67. If the answers are rounded it will be 17%.

I need help on this question and please explain what I got wrong so I understand and what I'm supposed to do.
Answer:
A. 64
Step-by-step explanation:
In this problem, you're trying to find out what b is.
With the information that you have, you know that the answer will be 16, and your denominator (what you'll be dividing by) is 4. What you got wrong in this was thinking of it as "what times 4 equals 16", to which you got the answer 4 because 4*4=16. But, that's not exactly what you're supposed to be doing.
If we looked at it like that in this problem, you'd have b=4, making the equation then look like 4/4=16. This isn't true because 4/4=1.
Instead, to get the correct answer, you'll be multiplying 4, the denominator, by 16, our solution. With this, you'll get the answer A. 64.
If you have any more questions, feel free to reach out for help.
Answer:
We are given an equation of [tex]\frac{b}{4} = 16[/tex] and we need to determine what b is. The way that we would do this is what you did and we would multiply both sides by 4 which would get rid of the 4 in the fraction and this would end up multiplying 16 by 4 giving us [tex]b=64[/tex]. This would best match with option A which is 64.

Answer:
= 15
Step-by-step explanation:
21 + 15 = 36
36/2 = 18
Therefore, 15 is the missing number :33
Answer:
15.
Step-by-step explanation:
There are 6 ( even number) of values in the data so:-
the median is the mean of the 2 middle numbers.
Therefore, we have:
(x + 21)/2 = 18 where x is the missing number.
x + 21 = 2*18
x = 36 - 21 = 15.

A researcher wanted to see if different breeds of dogs preferred toys of certain colors. The researcher presented each dog with 3 toys, identical except that each was a different color, and recorded which toy the dog played with the most in a set time period. Here are the outcomes and partial results of a chi-square test (expected counts appear below observed counts):
The value for the test statistic and the p value on the test when the researcher wanted to see if different breeds of dogs will be x² = 0.9421 and 0.05 < p value < 0.10.
How to illustrate the research?From the information given, the null hypothesis is that the variables have no difference while the alternative hypothesis is that they have a difference.
The degree of freedom will be:
= (3 - 1) × (3 - 1)
= 4
The critical value is 9.4877. In this case, the p value is greater than the significance level. Therefore, we fail to reject the null hypothesis.

Answer:
m∠1 = 83
m∠2 = 97
m∠3 = 83
m∠4 = 97
m∠5 = 83
m∠6 = 97
m∠7 = 83
Step-by-step explanation:
When two lines are parallel,
Alternate interior angle are equal.Vertically opposite angles are equal.Sum of linear pair angles is 180.m∠8 = m∠4 = 97 ( Alternate interior angles )
m∠8 = m∠2 = 97 ( Alternate interior angles )
m∠6 = m∠4 = 97 ( Vertically opposite angles )
m∠2 and m∠3 are linear pair angles,
m∠2 + m∠3 = 180
97 + m∠3 = 180
m∠3 = 180 - 97
m∠3 = 83
m∠1 = m∠3 = 83 ( Vertically opposite angles )
m∠3 = m∠7 = 83 ( Alternate interior angles )
m∠7 = m∠5 = 83 ( Vertically opposite angles )
