You are trying to build a

zip line in your backyard. The zip line will be attached 8 feet above the ground and go to a mount Over the pool that is 14 feet away. How long does the zip line need to be reach the pool? Round to the nearest tenth.

### Answers

**Answer:**

14 feet

**Step-by-step explanation:**

The zip line is the distance between the pool and where the zip line was initially attached.

From the question, we understand that the pool is 14 feet away from the other end of the zip line (i.e. the initial attachment)

**Hence:**

**The required distance is 14 feet**

Another Logic is:

Take the first end of the zip line as point 0 feet

[tex]Pool = 14\ feet[/tex]

[tex]Distance = 14\ feet - 0\ feet[/tex]

[tex]Distance = 14\ feet[/tex]

50+ PTS PLEASE HELP WILL GIVE BRAINLIEST A right rectangular prism has these dimensions: Length: 1 1/4 units. Width: 5/8 unit. Height: 3/4 unit. How many unit cubes of side length 1/8 unit are required to pack the prism without any gap or overlap? 60 75 150 300

### Answers

**Answer:**

Volume of rectangular prism = 1 1/3 x 5/6 x 2/3 = 4/3 x 5/6 x 2/3 = 20/27

Volume of cube = 1/6 x 1/6 x 1/6 = 1/216

Number of cubes that will pack the rectangular prism = 20/27 / 1/216 = 160

eddibear3a and 47 more users found this answer helpful

**Step-by-step explanation:**

Volume of prism = l x w x h

Volume of right rectangular prism = 1 1/4 x 5/8 x 3/4 = 75/128

Volume of cube = s^3

= 1/8^3 = 1/512

Total cubes = volume of prism / volume of cube

Total cubes = 75/128 / 1/512

Total cubes = 300

Out of **40 points** Carl scored** 14 points** for his team during a game.

What is percentage?

In mathematics, a** percentage** is a **number** or** ratio** that can be expressed as a **fraction** of** 100**. t is often denoted using **% **symbol and it is a **dimensionless **number. Some common examples of percentage representation are - 55/33, 65/17 etc.

Given is Carl who scored **35% **of his basketball teams **40 points** during a game.

Assume that he scored **x points** during a game. Then, we can write -

Percentage of goals scored by Carl = **35%**

Total goals of the team = **40**

Therefore, the **number of goals** of carl are -

**x = 35% of 40**

x = 35/100 × 40

**x = 14**

Carl scored a total of **14 points.**

Therefore, out of **40 points** Carl scored** 14 points** for his team during the basket ball game.

An insurance company divides its policyholders into low-risk and high-risk classes. 60% were in the low-risk class and 40% in the high-risk class. Of those in the low-risk class, 80% had no claims, 15% had one claim, and 5% had two claims. Of those in the high-risk class, 50% had no claims, 30% had one claim, and 20% had two claims. (Write answers as exact decimals.)

a) What is the probability that a randomly selected policyholder is high-risk and filed no claims?

b) What is the probability that a randomly selected policyholder filed two claims?

### Answers

**Answer:**

a). 0.294

b) 0.11

**Step-by-step explanation:**

From the given information:

the probability of the low risk = 0.60

the probability of the high risk = 0.40

let [tex]C_o[/tex] represent no claim

let [tex]C_1[/tex] represent 1 claim

let [tex]C_2[/tex] represent 2 claim :

For low risk;

so, [tex]C_o[/tex] = (0.80 * 0.60 = 0.48), [tex]C_1[/tex] = (0.15* 0.60=0.09), [tex]C_2[/tex] = (0.05 * 0.60=0.03)

For high risk:

[tex]C_o[/tex] = (0.50 * 0.40 = 0.2), [tex]C_1[/tex] = (0.30 * 0.40 = 0.12) , [tex]C_2[/tex] = ( 0.20 * 0.40 = 0.08)

Therefore:

a), the probability that a randomly selected policyholder is high-risk and filed no claims can be computed as:

[tex]P(H|C_o) = \dfrac{P(H \cap C_o)}{P(C_o)}[/tex]

[tex]P(H|C_o) = \dfrac{(0.2)}{(0.48+0.2)}[/tex]

[tex]P(H|C_o) = \dfrac{(0.2)}{(0.68)}[/tex]

[tex]P(H|C_o) = 0.294[/tex]

b) What is the probability that a randomly selected policyholder filed two claims?

the probability that a randomly selected policyholder be filled with two claims = 0.03 + 0.08

= **0.11**

**Answer:**

**Step-by-step explanation:**

First, distribute the 2 into the parenthesis (multiply the 2 by x+3) to get:

2x+6=8

Now subtract 6 from each side to get:

2x=2

Finally, divide each side by 2:

x=1

Solve the equation.

### Answers

**Answer:**

**Step-by-step explanation:**

y+6=-3y+26

first you should collect the like terms

y+3y =26-6

now you should add and subtract

yah you should divide by both sides by **4** so that we can have the value of** ****y**

**4****y****=****2****0**

**4**** **** **** **** ****4**

*y**=**5*

**Answer:**

**y = 5**

**Step-by-step explanation:**

Simplifying

y + 6 = -3y + 26

Reorder the terms:

6 + y = -3y + 26

Reorder the terms:

6 + y = 26 + -3y

Solving

6 + y = 26 + -3y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '3y' to each side of the equation.

6 + y + 3y = 26 + -3y + 3y

Combine like terms: y + 3y = 4y

6 + 4y = 26 + -3y + 3y

Combine like terms: -3y + 3y = 0

6 + 4y = 26 + 0

6 + 4y = 26

Add '-6' to each side of the equation.

6 + -6 + 4y = 26 + -6

Combine like terms: 6 + -6 = 0

0 + 4y = 26 + -6

4y = 26 + -6

Combine like terms: 26 + -6 = 20

4y = 20

Divide each side by '4'.

y = 5

Simplifying

**y = 5**

According to the National Health Survey, the weights of

individuals are normally distributed. Men have an average

weight of 172 pounds, with a standard deviation of 29 pounds.

Suppose we select 64 male students from Math 203. Find the

sample standard deviation for this sample. Give your answer to

three decimal points.

### Answers

Answer:

3.625

Step-by-step explanation:

Given a normal distribution :

Average weight = population mean = 172 pounds

Population standard deviation = 29 pounds

Number of samples selected(n) = 64

The standard deviation of the sample also called the standard error is the proportion of the population standard deviation to the square root of the number samples.

Sample standard deviation :

Population standard deviation /√n

= 29 /√64

= 29 / 8

= 3.625

the equation y = 5x represents a proportional relationship. What is the constant proportionality

### Answers

**Answer:**

5x

**Step-by-step explanation:**

It is the constant slope 5 over 1

The equation y = 5x represents a **proportional relationship. **5x exists the **constant proportionality**. It is the constant slope 5 over 1.

What is meant by constant proportionality?

A ratio connecting two values that are provided to one another in a so-called **proportional relationship** is known as a constant of proportionality.

Constant ratio, constant rate, unit rate, **variable constant**, and even rate of change are other names for the constant of proportionality.

When two or more **parameters **are proportional to one another either directly or indirectly, their relationship is stated as a = kb or a = k/b, where k denotes the direction of the relationship between the two variables.

The **proportionality constant**, k, is often used.

On the coordinate plane, proportionality is easily visualized as a **straight line.**

The **slope **or increase is constant because a proportional change does not occur along both the x-axis and the y-axis.

Let the equation y = 5x represents a **proportional relationship. **

5x exists the constant proportionality. It is the constant slope 5 over 1.
