Answer:

105.12 ft²

Step-by-step explanation:

Let's first find the area of the rectangle.

$10\cdot8=80$ ft², so the rectangle has an area of 80ft².

To find the area of the semi-circle, we find the area of a whole circle and divide by two.

The formula to find the area of a circle is $\pi r^2$ . The radius is 4, as the diameter is 8.

$3.14\cdot4^2$

$3.14\cdot16$

$50.24\div2=25.12$

Add 80 and 25.12:

$80+25.12=105.12$

Hope this helped!

Answer: 56 large cars and 86 small cars.

Step-by-step explanation:

Let's call:

$l$ : the number of large cars.

$s$ : the number of small cars.

Then, you can set up the following system of equations:

$\left \{ {{l+s=142} \atop {5.50l+4.0s=652.50}} \right.$

You can use the Elimination Method:

- Multiply the first equation by -4.0

- Add both equations.

- Solve for l.

$\left \{ {{-4.0l-4.0s=-568} \atop {5.50l+4.0s=652.50}} \right.\\--------\\1.5l=84.5$

$l$ ≈ $56$

Substitute $l=56$ into one of the original equations and solve for <em>s:</em>

<em> </em> $56+s=142\\s=142-56\\s=86$

lions [1.4K]

Answer:

"30 years or less when, in reality, the average age is more than 30 years"

Step-by-step explanation:

Type I error is produced when conclusion rejects a true null hypothesis.

The null hypothesis is

"The average gamer is more than 30 years old"

(deduced from the wording, not explicitly stated).

Then if the conclusion is "the average gamer is less than or equal to 30 years old" when in reality the average age is more than 30 years, then there is a type I error, since the null hypothesis is rejected.

Answer is D:

"30 years or less when, in reality, the average age is more than 30 years"
