Answer:

d = 110

Step-by-step explanation:

From the table of values given, we know that the ratio of dollar to ticket is 5 : 8.

Therefore, the amount of dollar to 176 dollars would be d : 176.

Using this proportion, we can find the value of d as shown below:

5 : 8 = d : 176

$\frac{5}{8} = \frac{d}{176}$

Multiply both sides by 176

$\frac{5}{8}*176 = \frac{d}{176}*176$

$\frac{5*176}{8} = d$

$\frac{880}{8} = d$

$110 = d$

d = 110

The volume, V, of the right circular cone with radius r and height h, shown below, can be found using the formula V = one-thirdp

djyliett [7]

V= 1/3π*r^2*h
⇒ 142 cm^(2)= 1/3π*r^(2)*(8.5 cm)
⇒ ...
⇒ r= 3.994.

Rounded to the nearest centimeter, the final answer is 4 cm.

Hope this helps~

You want to order carpet for an area in your house. The room measures 12 feet by 10 feet. Remember, Area = Length × Width.

Wewaii [24]

Answer:

3630 dollars

Step-by-step explanation:

First, we need to find the area of the the room floor. To do this, we need to do 12 × 10 because 12 is the length and 10 is the width. 12 × 10 is 120. We also know that each square yard of carpet costs $30.25. We now have to multiply 120 × 30.25 because the room is 120 square feet large. 120 × 30.25 = 3630, so the carpet costs $3630.

Each whole number from 0 to 9 is paired with its opposite. is this a function or not

dimaraw [331]

A function has the property that each element of the domain maps to only one element. For example, if there's ever the case where a relation includes point (1,2) and (1,3) then that relation is not a function. So for each case write down all the points as described. If one point in the domain ever maps to two different points, then it's not a function

Ad libitum [116K]

Answer:

The Sample Size Need To be at least 114

Step-by-step explanation:

According to the Question,

Given, A university dean of students wishes to estimate the average number of hours students spend doing homework per week. The standard deviation from a previous study is 6.2 hours.

The Maximum Error(E) is given as 1.5 hours and the standard deviation(σ) is 6.2 hours.

Now, For 99% Confident the level of value α is 0.01.

α/2 = 0.01/2 ⇒ 0.005

Thus, From The table, We get that the value of $Z_{alpha/2}$ is 2.58.

Hence, the sample size n can be found as

n = { $\frac{(Z_{alpha/2} * Standard Deviation)}{E}$ }²

n = {2.58 × 6.2}² / 1.5²

n = 113.72 .

So, The Sample Size Need To be at least 114.
