Answer:

Step-by-step explanation:

1.From the given triangle, ABC, using the proportionality theorem, we get

$\frac{FA}{CA}=\frac{EF}{BC}$

⇒ $\frac{8}{40}=\frac{5}{x}$

⇒ $x=25ft$

Thus, the height will be 25 feet.

2.

Statement Reason

1.∠C≅∠E Given

2. ∠ABC≅∠DBE Vertically opposite angles

3. ΔABC is similar to ΔDBE AA similarity rule.

It would have to be C. point.

Since it says AB that marks two points and a line in between them. If only talking about A, it would be a point.

A dart board has a circumference of 53.3 inches. What is the distance from the edge of the dart board to the exact center ofthe

loris [4]

Answer:

The solution is 8=r

Step-by-step explanation:

When the question states, "What is the distance from the edge of the dart board to the exact center of the bullseye (to the nearest inch)," it is basically asking to find the radius rounded to the nearest whole number given the circumference quantity.

Thus, we need to substitute the numbers already given into the radius equation.

53.3=2 x 3.14 x r

Now, divide both sides by 3.14.

16.97=2r

Again, use division property of equality and divide both sides of the equation by 2.

8.4=r ... then rounding to the nearest inch... 8=r

All things said, the solution is 8=r

I hope this helped!!

According to the Census Bureau, 3.36 people reside in the typical American household. A sample of 25 households in Arizona retir

Mila [183]

Answer:

We conclude that the mean number of residents in the retirement community household is less than 3.36 persons.

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 3.36

Sample mean, $\bar{x}$ = 2.71

Sample size, n = 25

Alpha, α = 0.10

Sample standard deviation, s = 1.10

First, we design the null and the alternate hypothesis

$H_{0}: \mu = 3.36\text{ residents per household}\\H_A: \mu < 3.36\text{ residents per household}$

We use One-tailed(left) t test to perform this hypothesis.

Formula:

$t_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{s}{\sqrt{n}} }$ Putting all the values, we have

$t_{stat} = \displaystyle\frac{2.71 - 3.36}{\frac{1.10}{\sqrt{25}} } = -2.95$

Now, $t_{critical} \text{ at 0.10 level of significance, 24 degree of freedom } =-1.31$

Since,

$t_{stat} < t_{critical}$

We reject the null hypothesis and fail to accept it.

Thus, we conclude that the mean number of residents in the retirement community household is less than 3.36 persons.
