is your answer number 4

Answer:

A

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

Answer: x=2, x=-1

Step-by-step explanation:

First you have to make it so that everything is on the same side so 2x^2+7x-4

Then you do cross multiply 2x=4 and x=0. I don't know really how to explain it but the answer is x=2 x=-1

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:

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:

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.

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.

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.

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.

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.

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.

Step-by-step explanation:

Step 1: Define

[tex]\displaystyle \frac{x^2 - 10x - 24}{x^2 - 3x - 108}[/tex]

Step 2: Simplify

We know that x cannot equal -9 because we would get a divide by 0 (undefined) error. We also know that x cannot equal 12 because it was canceled out when simplifying.
