The probabilities of at least 10 are repairable is 1/3. and probabilities of from 3 to 8 are repairable is 1/5*8/15 and probabilities of exactly 5 are repairable is 1/3.

According to the statement

we have given that If 15 actuators have failed and we have to find the probabilities on some conditions.

we know that the formula of probabilities is

probability = possible outcomes / total outcomes

So,

at least 10 are repairable = 1 - 10/15

at least 10 are repairable = (15 - 10)/15

at least 10 are repairable = (5)/15

at least 10 are repairable = 1/3

from 3 to 8 are repairable = 1/5 *8/15

exactly 5 are repairable = 1/3

These are the probabilities of the given conditions.

So, The probabilities of at least 10 are repairable is 1/3. and probabilities of from 3 to 8 are repairable is 1/5*8/15 and probabilities of exactly 5 are repairable is 1/3.

The difference between the theoretical probability and the experimental probability of the person getting the number 3 on a roll is 0.375.

In the question, we are given that a person has a 0.125 probability of getting the number 3 on a roll of an eight-sided die.

This means that the theoretical probability of rolling a 3 on an eight-sided die is 0.125.

Also, we are informed that a person rolls the die 24 times, and gets a 3 on one-half of the rolls, that is, 1/2 * 24 = 12 rolls.

Thus, the experimental probability of rolling a 3 on an eight-sided die = 12/24 = 1/2 = 0.5.

In the question, we are asked to find the difference between the theoretical probability and the experimental probability of the person getting the number 3 on a roll.

The difference = The experimental probability - The theoretical probability,

or, the difference = 0.5 - 0.125 = 0.375.

If the speed of boat in still water iss 9 mph and takes 1.5 miles to go and come 4 miles uptream and downward then the current of the river is 9.24 mph.

Given that the speed in still water be 9 mph, time to travel 4 miles upstream and downward is 1.5 hours.

We are required to find the speed of current of the river.

let the speed of current be c mph.

Effective speed in downstream=9+c

Effective speed in upstream=9-c

Total time=1.5 hours.

Total distance=4 miles.

Time for upstream stream+ time for downward stream=1.5 hours

Answer: 73

Step-by-step explanation:

I think she's 73? You have to take multiples of nine and see if they work! I did 72 since I knew that 72 goes into 9 equally and if she is 73 there would be a remainder of 1. After that, I stuck with 73 and since I knew that 18 times 4 is also 72, I knew that 73 divided by 4 would give me 18 with a remainder of 1.

The solution is 37 years, that is, Mrs. Laura's age is 37 years old.

Given information in the problem:

1. Mrs. Laura's, L age is between 50 and 80.

2. When you divide age by 9, the remainder is 1.

3. When you divide age by 4, the remainder is also 1.

To find L exact age, start by checking multiples of 9 that leave a remainder of 1 when divided by 4:

9 × 1 + 1 = 10 (remainder of 1 when divided by 4)

9 × 2 + 1 = 19 (remainder of 1 when divided by 4)

9 × 3 + 1 = 28 (remainder of 1 when divided by 4)

9 × 4 + 1 = 37 (remainder of 1 when divided by 4)

9 × 5 + 1 = 46 (remainder of 2 when divided by 4)

9 × 6 + 1 = 55 (remainder of 3 when divided by 4)

9 × 7 + 1 = 64 (remainder of 0 when divided by 4)

Check multiples of 4 that leave a remainder of 1 when divided by 9:

4 × 1 + 1 = 5 (remainder of 1 when divided by 9)

4 × 2 + 1 = 9 (remainder of 1 when divided by 9)

4 × 3 + 1 = 13 (remainder of 4 when divided by 9)

4 × 4 + 1 = 17 (remainder of 8 when divided by 9)

From the above calculations, see that the only common number between the two sets of multiples is 37.

So, L's age is 37 years old.

The rate of change of the angle of elevation of the balloon from the observer when the balloon is 100 feet above the ground is  1/20 degree/sec.

It is described as a relationship between an oblique line from the observer's eye to an item above his eye and the horizontal plane. This angle eventually develops above the surface. The angle of elevation is made in such a way that it is above the observer's eye, as the name suggests.

Calculation for the rate of change of angle of elevation-

According to the question,

A balloon rises at the rate of 10 ft/sec from a point on the ground 100 feet from an observer.

The balloon is 100 feet above the ground.

Let the height of the balloon be 'h' ft.

Then tanØ = h/100

h = 100tanØ

Differentiate the above equation with respect to time.

dh/dt = 100 sec² Ø (dØ/dt)

We know dh/dt = 10 ft/sec.

when h = 100

tanØ = 100/100 = 1/1

tanØ = Perpendicular/Base

On comparing above two equations,

Perpendicular = 1; Base = 1.

By Pythagoras the hypotenuse is,

H² = P² + B²

    = 1² + 1²

    = 2

H = √2

Now, calculate the value of cosØ.

cosØ = B/H = 1/√2

Squaring both side

cos² Ø = 1/2

sec² Ø = 1/cos² Ø

sec² Ø = 2

The main equation was,

dh/dt = 100 sec² Ø (dØ/dt)

Substitute the values,

dØ/dt = (dh/dt )/100 sec² Ø

         = (10)/(100×2)

dØ/dt = 1/20 degree/sec.

Therefore, the rate of change of the angle of elevation of the balloon from the observer is  1/20 degree/sec.
