Suppose the heights of 18-year-old men are approximately normally distributed, with mean 69 inches and standard deviation 6 inches.What is the probability that an 18-year-old man selected at random is between 68 and 70 inches tall? (Round your answer to four decimal places.)
Answer:
0.1350 = 13.50% probability that an 18-year-old man selected at random is between 68 and 70 inches tall
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score 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. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
[tex]\mu = 69, \sigma = 6[/tex]
What is the probability that an 18-year-old man selected at random is between 68 and 70 inches tall?
This is the pvalue of Z when X = 70 subtracted by the pvalue of Z when X = 68. So
X = 70
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{70 - 69}{6}[/tex]
[tex]Z = 0.17[/tex]
[tex]Z = 0.17[/tex] has a pvalue of 0.5675
X = 68
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{68 - 69}{6}[/tex]
[tex]Z = -0.17[/tex]
[tex]Z = -0.17[/tex] has a pvalue of 0.4325
0.5675 - 0.4325 = 0.1350
0.1350 = 13.50% probability that an 18-year-old man selected at random is between 68 and 70 inches tall

The relation of x and y (x,y) is not a function.
Relation is function if it is one-to-one.
One-to-one means to different value of x to get different value of y.
If function is not a function then one value of x to get two different value of y.
For first value of x=3, y=10
For which value of x= ? , y=20
x must be 3
x=3 to get y=20
The missing value of x is 3 because same of x we get two different value of y.

What are the potential solutions to the equation?
If this is the full question; What are the potential solutions to the equation below? 2In(x+3)=0
then the answer is; 2ln(x + 3) = 0
ln[(x + 3)²] = 0
(x + 3)² = 1
x + 3 = ±√1
x + 3 = ±1
x = 1 - 3, -1 - 3
x = -2, -1 - 3
x = -2, -4
when checking solution; x = -4 in the original equation does not hold true. so you drop x = -4 from the solution set.
therefore;
x = -2

A large pizza costs $12 and each topping costs an additional $2.50.
This situation can be represented by the equation y = 12 + 2.5x, where x represents the number of toppings and y represents the total cost.
What is the total cost for 9 toppings?
-$23.50
-$14.25
-$ 34,50
-$ 22.50
Answer:
$22.50
Step-by-step explanation:
So if each topping cost 2.50 then just multiply by 9

Janet's recipe calls for 3 cups of flour for every 2 cups of sugar. How much sugar does
Janet need, when she uses 9 cups of flour?
a) 6 cups b) 2⁄3 cup c) 8 cups d) 5 cups
Answer:
a) 6 cups
Step-by-step explanation:
Use a ratio equation to solve:
3/2 = 9/x
Cross multiply to get:
3x = 18
Solve for x:
x = 6
Answer: a) 6 cups
Step-by-step explanation: The 3 cups to get to 9, is really double the amount, so if you double 3 then you double 2 and get 6. 3*2=6

A mailbox that is 4 1/2 feet tall casts a shadow that is 6 feet long. At the same time, a nearby ferris wheel casts a shadow 84 feet long. Find the height of the ferris wheel.
60 feet
Answer: 63 ft
Step-by-step explanation:
We can think of the shadow and height of objects as the catheti of a triangle rectangle.
We also know the relationship:
Tan(θ) = (opposite cathetus)/(adjacent cathetus)
if we define:
Tan(θ) = k (a real number, such that will be the same number for every object, because it depends on the angle θ that will depend on the position of the sun)
opposite cathetis = heigt.
adjacent cathetus = length of the shadow.
Then we have:
k = height/length of the shadow.
For the mailbox, we know that the height is (4 + 1/2) ft and the shadow is 6ft long, then we have the equation:
k = (4 + 1/2)ft/6ft = 0.75
Then for the ferris wheel we know:
shadow length = 84ft
we can write the same equation as above:
k = 0.75 = height/84ft
0.75*84ft = height = 63ft
The ferris wheel is 63 ft high.
Answer:
63 feet

Study this incomplete image of a geometric construction. This image may result from the construction of ____
A. a line parallel to line AB through C.
B. a perpendicular to line AB.
The next step in this construction is to set the compass width to
A. line segment DC and draw an arc centered at D intersecting the second arc.
B. line segment KC and draw an arc centered at K intersecting the second arc.
C. arc IJ and draw an arc centered at K intersecting the second arc.
D. line segment CI and draw an arc centered at I intersecting the second arc.
Thank you.
Answer:
A line parallel to line AB through C & arc IJ and draw an arc centered at K intersecting the second arc
Step-by-step explanation:
This image may result from the construction of a line parallel to line AB through C.
The next step in this construction is to set the compass width to arc IJ and draw an arc centered at K intersecting the second arc.
What is Construction?Geometric constructions are precise drawings of geometrical shapes, angles, and lines. We will need a pencil, a ruler (or other straight edge), and compasses to do this.
Given:
From the image we can see that there is an attempt to make a copy of angle and proceeds to draw a parallel line.
So, This image may result from the construction of a line parallel to line AB through C.
Now, the next step can be measure the arc IJ from compass and put the pointer on K with same measurement and cut the Arc.
