In a certain process, the probability of producing a defective component is 0.07. (a) In a random sample of 8 chosen components, what is the probability that at most one component is defective

### Answers

**Answer:**

**Probability of at most one defective component = 0.89**

**Step-by-step explanation:**

Using the binomial distribution formula: ⁿCₓ * pˣ * qⁿ⁻ˣ

where n = number of sample

x = number of defective

p = probability of defective

q = probability of good = (1 - p)

For the question, n = 8; x = 0 or 1 (none or at most one defective); p = 0.07; q = 0.93

Probability of none defective, x = 0 :

⁸C₀ * 0.07⁰ * 0.93⁸ = 0.55

Probability of 0one defective, x= 1

⁸C₁ * 0.07¹ * 0.93⁸⁻¹ = 0.34

Probability of at most one defective component = 0.559 + 0.336 = 0.895

**Probability of at most one defective component = 0.89**

It takes four workers six hours and 45 minutes to plant 24 trees. If the time it takes to plant trees varies directly with the number of trees and inversely with the number of workers, how many trees could 9 workers plant in four and a half hours?

### Answers

Answer:

36 trees

Step-by-step explanation:

We are told that It takes four workers six hours and 45 minutes to plant 24 trees. Also that the time it takes to plant trees varies directly with the number of trees and inversely with the number of workers.

Thus,

t ∝ x/n

Where;

x is number of trees

n is number of workers

Now, opening the proportion symbol, we have;

t = kx/n

Where k is the constant of proportionality.

t = 6 hours 45 minutes = 6¾ hours = 6.75 hours

Plugging in the relevant values, we have;

6.75 = 24k/4

k = 4 × 6.75/24

k = 1.125

Now, we want to know how many trees could 9 workers plant in four and a half hours (4.5 hours)

Applying the same as above and Plugging in k = 1.125, we have;

4.5 = 1.125x/9

x = 9 × 4.5/1.125

x = 36 trees

### Answers

**Answer:**

The fries cost 2 dollars and the onion rings cost 3

**Step-by-step explanation:**

For the first question, we know that together, they equal 5 dollars. I assume that these will be divided to be one of the dishes costing 3 and the other costing two. I then plug these in with the numbers of the dishes ordered and see what fits with the final cost.

**Answer:**

fries are $2 onion rings $3

**Step-by-step explanation:**

say fries are y and onion rings are X we get two simultaneous equations

y+x= 5 and 3y+2x=12

equal either X or y, I will do x

2y+2x=10 and 3y+2x=12

take the first equation fromm the second

y=2

them sub y into one of the original equations to solve X,

y+x=5

2+X=5

An auto club drove a new hybrid car 442.4 miles. They refilled the gas tank with 10.2 gallons of gas. How many miles per gallon did the hybrid car get? A. 4.33 B. 4.46 C. 43.37 D. 44.63

### Answers

**Answer:**

The correct answer is D. The hybrid car got 43.37 miles pero gallon.

**Step-by-step explanation:**

To determine the number of miles traveled for each gallon of gasoline consumed by the car, the number of miles traveled must be divided by the number of gallons consumed.

Thus, if 442.4 miles were traveled and 10.2 gallons of gasoline were consumed, the following calculation should be performed:

442.4 / 10.2 = X

43.37 = X

Therefore, for every gallon consumed 43.37 miles were traveled.

Mary ran at a steady speed in a 10-mile race. Her finish time was 2 hours. Mary can bike the same

distance in

hour. Mary wants to know her running speed and biking speed in miles per hour.

Which fraction represents Mary's running

speed in miles per hour?

1/2/10, 1/2, 10/2, or 10/1/2?

### Answers

We want to get Mary's **running speed** and **biking speed.** We will get that her **running speed **is **5 mi/h**, while her **biking speed** is **10 mi/h.**

**Finding the speed:**

First, you need to remember that **speed **is defined as the **rate **at which the position changes with respect to the time.

Then we can write:

speed = (distance/time).

When she runs, she completes a **distance **of 10 miles in a **time **of 2 hours, then her **running speed** is:

[tex]S_R =\frac{10mi}{2h} = 5 mi/h[/tex]

When she bikes, she completes that distance in 1 hour, then her **biking speed** is:

[tex]S_B = \frac{10mi}{1h} = 10mi/h[/tex]
