88 = h + 36 I need help
Answer:
h=52
Step-by-step explanation: You subtract 36 from both sides and it cancels on the right but on the left you do regular subtraction and you get that h equals 52
Answer:
h = 52
Step-by-step explanation:
h + 36 = 88
subtract 36 from both sides
h = 52

Answer:
Suppose that you have a random point (x, y), and now you do a dilation from the origin with a scale factor of k.
Then the new coordinates of the point are:
(k*x, k*y)
Now, in this question, we have a dilation of scale factor k = 1/2.
Then if we start with the point (x, y), after the dilation we will have the point (x/2, y/2)
Now you can notice that instead of this, in the table we have (2*x, 2*y)
So this is the error, the transformation is not correctly calculated.

Water is shot straight up out of a water soaker toy.
The quadratic function y = –16x2 + 32x models the
height in feet of a water droplet after x seconds. How
long is the water droplet in the air?
Help!
Answer:
The water droplet is in the air for two seconds.
Step-by-step explanation:
You can solve this by finding the times at which its height is zero. The lesser of the two values will be upon launch, and the greater upon landing:
y = -16x² + 32x
Let y = 0
-16x² + 32x = 0
factor -16 out:
x² - 2x = 0
complete the square:
x² - 2x + 1 = 1
and solve for x
(x - 1)² = 1
x - 1 = ±1
x = 1 ± 1
x = 0, 2
So the water is at a height of zero at zero seconds and two seconds. It's thus in the air for two seconds.

find the value of x
Answer:
x = 7
Step-by-step explanation:
A right angle is equal to 90 degrees
The sum of the angles, 55 and 5x, should equal 90
55 + 5x = 90
Isolate the variable
Subtract both sides by 55
55 - 55 + 5x = 90 - 55
5x = 35
Divide both sides by 5
5x ÷ 5 = 35 ÷ 5
x = 7

Answer:

Step-by-step explanation:
You should know the area of a circle, A = πr².
So, all you need to find is the area of half a circle, or A = [tex]\frac{1}{2}[/tex] πr²
We see that the radius is half of the diameter or r = 6 in.
A = [tex]\frac{1}{2}[/tex] (3.14)(6)²
A = 56.52 in²

The trip from Manhattan to Montauk Point is 120 miles by train or by car. A train makes the trip in 2 hours, while a car makes the trip in 2.5 hours. How much faster in miles per hour, is the average speed of the train than the average speed of the car?
Answer:
30mph faster
Step-by-step explanation:
first you must find how fast the train can go in 1 hour
that is 60mph, then multiply 60 and 2.5
60x2.5 = 150mph then,
150 - 120 =30mph
very sorry if this is wrong
The average speed of the train is 1.25 times the average speed of the car.
What is speed?Speed is defined as the length traveled by a particle or entity in an hour. It is a scale parameter. It is the ratio of length to duration.
We know that the speed formula
Speed = Distance/Time
The excursion from Manhattan to Montauk Point is 120 miles via train or via vehicle. A train makes the outing in 2 hours, while a vehicle makes the excursion in 2.5 hours.
The average speed of the train is given as,
⇒ 120 / 2
⇒ 60 miles per hour
The average speed of the car is given as,
⇒ 120 / 2.5
⇒ 48 miles per hour
The ratio of the average speed of the train to the car will be given as,
⇒ 60/48
⇒ 1.25
The average speed of the train is 1.25 times the average speed of the car.
More about the speed link is given below.

A random sample of adult men was asked if they would return the money if they found a wallet on the street. Of 143 men, 29 said they would. The true proportion of all adult men who would return the money is 18%. Which of the following do you expect would accurately describe the sampling distribution of the sample proportion of men would return money from a found wallet?
Select one or more:
a. The mean of the sampling distribution will be equal to 0.18.
b. The mean of the sampling distribution will be equal to 0.2028.
c. The sampling distribution would be approximately standard normal.
d. The sampling distribution will be skewed right.
e. The sampling distribution will be skewed left.
f. The sampling distribution will be approximately normal.
g. The standard deviation of the sampling distribution will be 0.0336.
Answer:
b. The mean of the sampling distribution will be equal to 0.2028.
f. The sampling distribution will be approximately normal.
g. The standard deviation of the sampling distribution will be 0.0336.
Step-by-step explanation:
We use the Central Limit Theorem to solve this question.
Central Limit Theorem:
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex].
The sample proportion being approximately normal means that option f. is correct.
Of 143 men, 29 said they would.
This means that [tex]p = \frac{29}{143} = 0.2028[/tex]
This means that option b is correct.
g. The standard deviation of the sampling distribution will be 0.0336.
Lets find the standard deviation.
Sample of 143, so [tex]n = 143[/tex]
[tex]s = \sqrt{\frac{0.2028*0.7972}{143}} = 0.0336[/tex]
So option g. is correct.
The statements that accurately describe the sampling distribution of the sample proportion of men would return money from a found wallet are;
B) The mean of the sampling distribution will be equal to 0.2028.
F) The sampling distribution will be approximately normal.
G) The standard deviation of the sampling distribution will be 0.0336.
Central Limit Theorem.
We are given the true proportion of all adult men who will return the money as; p = 18% = 0.18
Thus, the population mean = 0.18
Now, out of 143 men, 29 said they will return the money. Thus;
Sample mean = Sample proportion = 29/143 = 0.2028
The formula for the sampling standard deviation is;
s = √[p^(1 - p^)/n]
s = √[0.2028(1 - 0.2028)/143]
s = √0.001130574545
s = 0.0336
Looking at the options and comparing to the answers gotten above, only option B, F and G are correct.
