Answer:
9 cm
Step-by-step explanation:
Given that angle Y = 90 means that the triangle is a right angle triangle
If angle X = 30 degrees and xz =18 cm
xz is the hypotenuse side while zy is the opposite side considering the angle at X
Hence using the notation SOH CAH TOA
SOH
Sin X = zy/xz
Substituting
Sin 30 = zy/18
cross multiply
zy = 18 sin 30
zy = 18 * 0.5
= 9 cm
Answer:
9 cm

A shop foreman found that it takes 40 minutes on average to complete a
specific task. Given that the standard deviation for this task is 6 minutes
and the times for completing this task are normally distributed, what is
the probability that on any given day it will take between 34 and 44
minutes to complete the task?
Answers
Using the normal distribution, it is found that there is a 0.5899 = 58.99% probability that on any given day it will take between 34 and 44 minutes to complete the task.
In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.In this problem:
Mean of 40 minutes, hence [tex]\mu = 40[/tex].Standard deviation of 6 minutes, hence [tex]\sigma = 6[/tex].The probability that on any given day it will take between 34 and 44 minutes to complete the task is the p-value of Z when X = 44 subtracted by the p-value of Z when X = 34, hence:
X = 44:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{44 - 40}{6}[/tex]
[tex]Z = 0.67[/tex]
[tex]Z = 0.67[/tex] has a p-value of 0.7486
X = 34:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{34 - 40}{6}[/tex]
[tex]Z = -1[/tex]
[tex]Z = -1[/tex] has a p-value of 0.1587
0.7486 - 0.1587 = 0.5899.
0.5899 = 58.99% probability that on any given day it will take between 34 and 44 minutes to complete the task.

Answers
Answer:
we can make some assumptions b/c of the marks. on the sides, the double marks means they are the same, and the single marks are also the same length. because those sides are the same lengths.. we can just add up all the sides to find the length around the shape... or the perimeter of it.
Step-by-step explanation:
I'll start with the 14 on the left, and go counter clock wise
14 + 6 + 9 + 5 + 9 + 7 + 14 + (6+7+5) = Perimeter
the last numbers in the parenthesis are from the sides opposite of the long top side, the parts of the other sides adds up to the long top side... sooo,
Perimeter = 82 ( I added in my head , so use a calculator to double check )

1. When Jack and Jill work together, they can carry a cooler of
water up a hill in 12 hours. When Jill works alone it takes her
7 fewer hours than when Jack works alone. How long would it
take Jack, working alone, to carry a cooler of water up a hill?
Answers
9514 1404 393
Answer:
28 hours
Step-by-step explanation:
Let x represent Jack's time. Then Jill's is x-7. Together their rate of carrying water in hills per hour is ...
1/x + 1/(x -7) = 1/12
Multiplying by 12x(x -7) gives ...
12(x -7) +12x = x(x -7)
x^2 -31x +84 = 0 . . . . . subtract the left side and simplify
(x -3)(x -28) = 0 . . . . . . . . . . factor
x = 3 or x = 28 . . . . . . . . . . x-values that make the factors zero
We know the times must be longer than 12 hours, so the value x=3 is extraneous for this problem.
It takes Jack 28 hours to carry the cooler of water up the hill working alone.
If a shirt cost 9.99, but there was a sale that said 15% of the original price, how much was the shirt?
Answers
Answer: $8.49
To solve this problem, you want to find out how much 15% of 9.99 is. To do that you have to multiply 9.99 by 0.15 (which equals 1.4985) to find out how much the shirt was discounted. Then take that number and subtract 9.99 from it which gives you 8.4915 (or $8.49 rounded)

A bridge being designed will cross the river at a right angle. The equation of the left bank of the river is j = 2x+8. The center of the bridge will pass through (0,2). What is the equation of the line representing the bridge?
Answers
This is the same as y = -0.5x+2
==========================================================
Explanation:
Refer to the diagram below.
The blue line is the graph of y = 2x+8, which is the left bank of the river.
For now, ignore the y = (-1/2)x+2 in the diagram and pretend we don't know that just yet. The red line is the bridge and it's some linear equation in the form y = mx+b. We're told the bridge is perpendicular to the river, so the bridge must also be perpendicular to the riverbank.
The blue line has slope m = 2. Apply the negative reciprocal to this to end up with -1/2. This is the perpendicular slope, and the slope of the red line. Note how the two slopes (2 and -1/2) multiply to -1. Any two perpendicular lines will have their slopes multiply to -1, as long as neither line is vertical or horizontal.
Since we want the bridge to pass through (0,2), this must mean the y intercept is b = 2.
So with m = -1/2 and b = 2, we go from y = mx+b to y = (-1/2)x + 2 which is the equation of the bridge shown in red.
This is the same as y = -0.5x + 2 since -1/2 = -0.5
