Answer:

22, 23, 24, and 25.

Step-by-step explanation:

The sum of four consecutive integers is 94, and we want to determine the integers.

Let x be the first integer. Since they are consecutive, the second will be (x + 1), the third (x + 2), and the fourth (x + 3).

They sum to 94. Hence:

\(\displaystyle x + (x+1) + (x+2) + (x+3) = 94\)

Solve for x. Combine like terms:

\(4x + 6= 94\)

Subtract:

\(\displaystyle 4x = 88\)

And divide. Hence:

\(\displaystyle x = 22\)

Therefore, the first term is 22.

Then the four integers are 22, 23, 24, and 25.

Using the radius of the Ferris wheel and the angle between the two positions, the time spent on the ride when they're 28 meters above the ground is 12 minutes

The radius of the Ferris wheel is 30 / 2 = 15 meters.

The highest point on the Ferris wheel is 15 + 4 = 19 meters above the ground.

The time spent higher than 28 meters is the time spent between the 12 o'clock and 8 o'clock positions.

The angle between these two positions is 180 degrees.

The time spent at each position is 10 minutes / 360 degrees * 180 degrees = 6 minutes.

Therefore, the total time spent higher than 28 meters is 6 minutes * 2 = 12 minutes.

Answer:

\(P(z<\frac{a-\mu}{\frac{\sigma}{\sqrt{n}}})=0.1\)

And replacing the value obtained we got:

\(z=-1.282<\frac{a-410000}{\frac{\sigma}{\sqrt{200}}}\)

And if we solve for a we got

\(a=410000 -1.282*\frac{65000}{\sqrt{200}}=404107.68\)

Step-by-step explanation:

Let X the random variable that represent the average home prices of a population, and for this case we know the distribution for X is given by:

Where \(\mu=410000\) and \(\sigma=65000\)

For this part we want to find a value a, such that we satisfy this condition:

\(P(X>a)=0.90\)   (a)

\(P(X<a)=0.10\)   (b)

We want to find a value who accumulate 0.10 of the area on the left and 0.90 of the area on the right of the normal standard distributon and for this case it's z=-1.282

And using the distribution for the sample mean we can do this:

\(P(X<a)=P(\frac{X-\mu}{\frac{\sigma}{\sqrt{n}}}<\frac{a-\mu}{\frac{\sigma}{\sqrt{n}}})=0.10\)  

\(P(z<\frac{a-\mu}{\frac{\sigma}{\sqrt{n}}})=0.1\)

And replacing the value obtained we got:

\(z=-1.282<\frac{a-410000}{\frac{\sigma}{\sqrt{200}}}\)

And if we solve for a we got

\(a=410000 -1.282*\frac{65000}{\sqrt{200}}=404107.68\)

Answer:

8 hours and 26 minutes

Step-by-step explanation:

To convert 506 minutes to hours and minutes, we can use the fact that there are 60 minutes in one hour.

First, we can divide 506 by 60 to find the number of hours:

506 ÷ 60 = 8 with a remainder of 26

This means that 506 minutes is equal to 8 hours and 26 minutes.

Therefore, the conversion of 506 minutes to hours and minutes is:

8 hours and 26 minutes

Answer:

The volume of the cylinder is given by the formula: V = πr^2h, where r is the radius and h is the height. In this case, the height is equal to the diameter of the hemisphere (which is also the diameter of the paperweight), so we have:

V = π * 9^2 * (2 * 9) = 904π cm^3

The volume of the cone is given by the formula: V = (1/3)πr^2h, where r is the radius and h is the height. In this case, the height is equal to the diameter of the hemisphere, and the radius is half the diameter, so we have:

V = (1/3)π * (9/2)^2 * (2 * 9) = 188π cm^3

To estimate the volume of the hemisphere, we find the average of the volumes of the cylinder and cone:

V = (904π + 188π) / 2 = 546π cm^3

If the radius of the hemisphere is 12 cm, its diameter is 2 * 12 = 24 cm.

If the radius of the hemisphere is x m, its diameter is 2 * x m.

If the radius of the hemisphere is 12.004 ft, its diameter is 2 * 12.004 = 24.008 ft.

If the diameter of the hemisphere is 12 cm, its radius is 12 / 2 = 6 cm.

If the diameter of the hemisphere is x m, its radius is x / 2 m.

If the diameter of the hemisphere is 12.004 ft, its radius is 12.004 / 2 = 6.002 ft.

Answer:

A soda bottle contains 2 liters of liquid. Therefore:

The soda bottle contains  67.62 fluid ounces of liquid.

The soda bottle contains 0.525  gallons of liquid.

2) A milk jug contains 2 gallons of milk. Therefore:

The milk jug contains 8  quarts of milk.

The milk jug contains 7.6 liters of milk.

Step-by-step explanation:

We need to complete the statements.

1)

A soda bottle contains 2 liters of liquid. Therefore:

The soda bottle contains -------  fluid ounces of liquid.

We know that 1 liter = 33.81 fluid ounces

So,  2 liter = 2 x 33.81 = 67.62 fluid ounces

The soda bottle contains 67.62  fluid ounces of liquid.

The soda bottle contains  gallons of liquid.

As, we are not given direct conversion from liters to gallons, first we convert liter to quarts and then convert quarts to gallons

We know that

1 liter = 1.05 quarts

2 liters = 2 x 1.05 = 2.1 quarts

4 quarts = 1 gallon

1 quarts = 1/4 gallon

2.1 quarts = 1/4 * 2.1 = 0.525 gallon

The soda bottle contains 0.525  gallons of liquid.

2)

A milk jug contains 2 gallons of milk. Therefore:

The milk jug contains -------- quarts of milk.

We know:

1 gallon = 4 quarts

2 gallons = 2 x 4 = 8 quarts

The milk jug contains 8 quarts of milk.

The milk jug contains ------  liters of milk.

We know:

1 gallon = 4 quarts

2 gallon = 8 quarts

1.05 quarts = 1 liter

1 quarts = 1/1.05 liter

8 quarts = 1/1.05 * 8 = 7.6 liter

The milk jug contains 7.6 liters of milk.

The probability that a randomly selected x-value from the distribution will be in the interval:

The probability of a normal distribution can be determined from the symmetrical curve between 1 to 100%.

From the information given:

To determine the probability that a randomly selected x-value is in the given interval:

\(P(35 < x < 45) = P(\dfrac{35-40}{5} < Z < \dfrac{45-40}{5})\)

\(P(35 < x < 45) = P(\dfrac{-5}{5} < Z < \dfrac{5}{5})\)

\(P(35 < x < 45) = P(-1 < Z < 1)\)

\(\mathbf{P(35 < x < 45) = P[Z\le 1] -P[Z\le -1]}\)

Using normal distribution table:

P(35 < x < 45) = 0.8414 - 0.1587

P(35 < x < 45) = 0.6827

\(P(30 < x < 40) = P(\dfrac{30-40}{5} < Z < \dfrac{40-40}{5})\)

\(P(30 < x < 40) = P(\dfrac{-10}{5} < Z < \dfrac{0}{5})\)

\(P(30 < x < 40) = P(-2 < Z < 0)\)

\(\mathbf{P(30 < x < 40) = P[Z\le0]-P[Z\le -2]}\)

greatest no. 9982,9929.

Answer:94.2

Step-by-step explanation: i think

a) The probability that a single randomly selected value is less than 146 is 0.7823 (rounded to four decimals).

b) Therefore, the probability that a sample of size n = 20 is randomly selected with a mean less than 146 is 0.9892 (rounded to four decimals).

To find the probability that a single randomly selected value is less than 146, we first need to standardize the value using the formula:

Z = (X - μ) / (σ / √n)

where X is the value, μ is the mean, σ is the standard deviation, and n is the sample size.

Substituting the given values, we get:

Z = (146 - 114.3) / (74.6 / √20) = 0.787

From the Z table, the probability for a Z score of 0.787 is 0.7823.

b) To find the probability that a sample of size n = 20 is randomly selected with a mean less than 146, we need to use the Central Limit Theorem, which states that the sample mean follows a normal distribution with mean μ and standard deviation σ / √n.

Using this information, we can standardize the sample mean using the formula:

Z = (M - μ) / (σ / √n)

Substituting the given values, we get:

Z = (146 - 114.3) / (74.6 / √20) = 2.2915

From the Z table, the probability for a Z score of 2.2915 is 0.9892.

    NO             \(m  =44.94 \% \)

   NOT SURE  \(m  =7.02\% \)

c

The correct option is (iv)

Step-by-step explanation:

From the question we are told that

The voting options are "Yes, " "No, " "Not sure, " or "Don't care."

The number of people that said is \(Y = 636\)

The number of people that said No is \(N = 595 \)

The number that indicated Not sure is \(S = 93\)

Generally the sample size is mathematically represented as

\(n = Y + N + S\)

=> \(n = 636 + 595 + 93\)

=> \(n = 1324\)

Generally the percentage of responses that was Yes is mathematically represented as

\(y = \frac{636}{ 1324} * 100\)

=>     \(y  = 48.03 \% \)

Generally the percentage of responses that was No is mathematically represented as

\(m = \frac{595}{ 1324} * 100\)

\(m =44.94 \% \)

Answer:

Either location costs the same when they play 4 games

Step-by-step explanation:

The total cost for playing putt-putt consists of fixed rentals and a variable amount per game.

On one location Ben and his friends can pay $2 rentals plus $7.50 per game.

If x is the number of games played, then the total cost at this location is:

C1(x) = 7.50x + 2

At another location, it would cost $8 for rentals plus $6 per game. The second function is:

C2(x) = 6x + 8

It's required to find the number of games x in order for either location to cost the same amount.

It can be done by equating both cost functions:

7.50x + 2= 6x + 8

Subtracting 2 and 6x:

7.50 - 6x = 8 -2

Operating:

1.5x = 6

Dividing by 1.5:

x = 6 / 1.5

x = 4 games

Either location costs the same when they play 4 games
