Answer:

He should measure the length of the bowling alley using meters

Step-by-step explanation:

The score does Tyrone need in the fifth game so that his mean score is 125 is 168.

It is defined as the sum of all observations divided by the number of observations.

Given

Tyrone's bowling scores for the first four games of the season were 120,123,105, and 109. He wants to increase his mean score to 125.

\(\frac{120+123+105+109+x}{4+1} =125\)

⇒ \(\frac{457+x}{4+1} =125\)

⇒ \(\frac{457+x}{5} =125\)

⇒ \({457+x} =125\) × \(5\)

⇒ \({457+x} =625\)

⇒ \(x =625-457\)

⇒ \(x =168\)

Hence, the score does Tyrone need in the fifth game so that his mean score is 125 is 168.

The probability that a randomly selected student is both a freshman and a chemistry major is approximately 0.8333. Given that the selected student is a freshman, the probability that she is also a chemistry major is approximately 0.3125.

In order to calculate the probability that a student is both a freshman and a chemistry major, we need to determine the number of students who fall into this category. According to the given information, there are 16 freshmen and 21 chemistry majors in the class.

However, we also know that 6 students are neither freshmen nor chemistry majors. Therefore, to find the number of students who are both freshmen and chemistry majors, we subtract the number of students who are neither from the total number of students: 36 - 6 = 30.

Now we can calculate the probability. The probability that a randomly selected student is both a freshman and a chemistry major is given by the ratio of the number of students who are both to the total number of students: 30/36 = 5/6, or approximately 0.8333.

Next, we need to find the probability that a selected student is a chemistry major given that she is a freshman. We know that there are 16 freshmen in total, and out of these, 21 students are chemistry majors. So the probability can be calculated as 21/16 = 1.3125.

However, since probabilities should be between 0 and 1, we need to normalize this value. The probability that a randomly selected student is a freshman and a chemistry major is approximately 0.3125.

Mario cut 8 small rectangles.

The probability that a randomly selected fish is a large, red fish is 0.25 or 25%.

To find the probability that a randomly selected fish is a large, red fish, we need to consider both the probability of selecting a large fish and the probability of selecting a red fish among the large fish.

Assuming an equal number of large and small fish, the probability of selecting a large fish is 0.5 (or 1/2).

Among the large fish, the probability of selecting a red fish is also 0.5 (or 1/2).

To find the overall probability, we multiply the probabilities of the individual events:

Probability of selecting a large, red fish = Probability of selecting a large fish × Probability of selecting a red fish among the large fish

Probability of selecting a large, red fish = 0.5 × 0.5

Probability of selecting a large, red fish = 0.25

Therefore, the probability that a randomly selected fish is a large, red fish is 0.25 or 25%.

The temperature decreases by 4% each minute.

What is the exponential decay

Exponential decay is a process in which a quantity decreases over time and the rate of decrease is proportional to the current value of the quantity. This means that as the quantity decreases, the rate of decrease slows down.

I believe there is an error in the given function. It seems to be missing the exponent for 0.96. Assuming that it should be "\(C(t) = 19(0.96)^t\)", I can provide the following solutions:

The initial temperature is the temperature when t = 0. Plugging in t = 0 into the function, we get:

\(C(0) = 19(0.96)^0 = 19(1) = 19\)

Therefore, the initial temperature is 19 degrees Celsius.

The function represents decay because the base of the exponential term (0.96) is between 0 and 1, causing the function to approach 0 as time goes on.

The percent change in temperature each minute can be calculated using the following formula:

Percent Change = (New Value - Old Value) / Old Value x 100%

For each minute that passes, the temperature decreases by a factor of 0.96. Therefore, the new temperature is 0.96 times the old temperature. Using the initial temperature of 19 degrees Celsius, we can calculate the percent change in temperature each minute as follows:

Percent Change = \((0.96 * 19 - 19) / 19 * 100%\)

= -4%

Hence, the temperature decreases by 4% each minute.

Answer:

the jacket price was reduced by 40%.

Step-by-step explanation:

if $50 is 100% then every one dollar is 2%.

Percentage of the reduction of price of the jacket is 40%.

Percentage is defined as the parts of a number per fraction of 100.

Percentage is usually denoted by the symbol '%'.

We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.

Given that,

Original price of the jacket = $50

Let x be the percentage of reduction of the price of the jacket.

50 - (x × 50) = 30

50x = 50 - 30

50x = 20

x = 20 / 50

x = 0.4

Percentage = 0.4 × 100 = 40%

Answer:

C

Step-by-step explanation:

The option that has the same range than f(x) is:

\(g(x) = -\sqrt{x + 3} + 8\)

Here we first have the function:

\(f(x) = -2*\sqrt{x - 3} + 8\)

Remember that the square root only can be evaluated arguments equal or larger than zero.

So the minimum value of x that we can use is x = 3.

\(f(3) = -2*\sqrt{3 - 3} + 8 = 8\)

And as x increases, the outcome will decrease (because the square root is being mulitiplyed by a negative number). So we can conclude that the range is y ≤ 8.

So, we need another function that has a maximum value in the range equal to positive 8, so we need to have a constant equal to 8, and a square root being multiplyed by a negative number.

The option that meets these two conditions is the third one:

The function f has the property injective. (D)

An injective function is also known as a one-to-one function, which means that for every unique output, there is a unique input.

In this case, the function f maps the single element in the domain {1} to the single element in the codomain {1}, and there is only one possible output for the single input, so it is injective.

It does not have the properties of being increasing, decreasing, strictly increasing, strictly decreasing, or surjective because the function is a constant function mapping the single element in its domain to the single element in its codomain.

As a result, it does not change in value and cannot be classified as increasing or decreasing. Additionally, it is not surjective because the codomain contains one element that is not mapped to by the function.

Answer:

3/2

Step-by-step explanation:

There are a lot of fractions that equal 1.5, but if you're asking for the most simplified fraction, 3/2 is the answer.

The predicted values of A, B, C, and D are: A = 595B = -0.5C = 600D = $6350, therefore, the correct option is IC.

Given,

Mean of X = 600

Standard deviation of X = 10

Mean of Y = $5000

Standard deviation of Y = 1000

Correlation r= 0.9

Future value of X = 595

Z score of X = (X- Mean of X) / Standard deviation of X= (595-600) / 10 = -0.5

Using the formula, Predicted y = average of y+ r* (Z score of X)* standard deviation of y

Predicted y = $5000 + 0.9 * (-0.5) * 1000 = $4750

The predicted value of Y for X = 595 is $4750.

Now, to find the values of A, B, C, and D; we need to calculate the Z score of X = 615 and find the corresponding predicted value of Y.

Z score of X = (X- Mean of X) / Standard deviation of X= (615-600) / 10 = 1.5

Predicted y = average of y+ r* (Z score of X)* standard deviation of y

Predicted y = $5000 + 0.9 * (1.5) * 1000 = $6350

The predicted value of Y for X = 615 is $6350.

Hence, the values of A, B, C, and D are: A = 595B = -0.5C = 600D = $6350

To convert radians to degrees, we need to multiply the radian measure by 180/π. Let's say we have an angle of 3π/4 radians. To convert this to degrees, we would do:

3π/4 * 180/π = 135 degrees

So our angle measures 135 degrees. Now let's determine which quadrant this angle lies in. A positive angle in the second quadrant will have a cosine value that is negative and a sine value that is positive. Using the unit circle, we can see that our angle of 135 degrees is in the second quadrant. Therefore, our cosine value is -cos(135) and our sine value is sin(135).

To find the tangent, we can use the formula tangent = sine/cosine. So our tangent value is:

tan(135) = sin(135)/cos(135) = (-√2/2)/(-√2/2) = 1

So the sine of our angle is √2/2, the cosine is -√2/2, and the tangent is 1.
Hi! To convert radians to degrees, use the formula:

degrees = radians × (180 / π)

First, determine the angle in radians. Let's say the angle is θ radians.

Step 1: Convert radians to degrees
θ degrees = θ × (180 / π)

Step 2: Determine the quadrant
Check the value of θ degrees to see which quadrant it lies in:
- 0° ≤ θ < 90°: Quadrant I
- 90° ≤ θ < 180°: Quadrant II
- 180° ≤ θ < 270°: Quadrant III
- 270° ≤ θ < 360°: Quadrant IV

Step 3: Calculate sine, cosine, and tangent
To find the sine, cosine, and tangent of the angle θ, you can use a calculator or a reference table:
- sin(θ) = sine of the angle
- cos(θ) = cosine of the angle
- tan(θ) = tangent of the angle = sin(θ) / cos(θ)

Make sure to use the angle in radians for these calculations. After finding the sine, cosine, and tangent values, you'll have the complete information about the angle in question.
