A) a number > 1
C) a number = 1
B) a number < 1
D) a number = 0

Answer: See explanation

Step-by-step explanation:

Number of students in the school band = 180

Sample selected = 20

Fraction of students that selected Cajun pasta. = 11/20

Fraction of students that selected chicken pasta = 4/20

Fraction of students that selected shrimp pasta = 5/20

Cajun pasta to be prepared = 11/20 × 180 = 99

Chicken pasta to be prepared = 4/20 × 180 = 36

Shrimp pasta to be prepared = 5/20 × 180 = 45

The length of the third side of the triangle is 2x+13.

According to the question,

We have the following information:

A triangle has a perimeter of 7x + 8. The first side of the triangle has a length of 3x, and the second side has a length of 2x − 5.

We know that perimeter of triangle is the sum of all three sides of triangle.

Let's take its third side to be y.

So, we have the following expression:

3x+2x-5+y = 7x+8

5x-5+y = 7x+8

Adding 5 on both the sides:

5x+y = 7x+8+5

5x+y = 7x+13

Subtracting 5x from both the sides:

y = 7x-5x+13

y = 2x+13

Hence, the correct option is B.

Answer:

2547

Step-by-step explanation:

Answer:

a. 0.6975

b. 0.25

c. The events are independent and inclusive

Step-by-step explanation:

a. The proportion of five-star football recruits in the nation that go to universities in the three most competitive athletic conferences = 75%

Therefore, the probability of a five-star football recruits chooses to go to a university in the three most competitive athletic conferences p(A) = 75% or 0.75

The proportion of the times five-star football recruits get full football scholarships = 93%

Therefore, the probability that a five-star football recruit get full football scholarships p(B) = 93% or 0.93

Therefore, the probability that a randomly selected five-star recruit who chooses one of the best three conferences will be offered a full football scholarship can be written as -the probability that a randomly selected five-star recruit who chooses one of the best three conferences and will be offered a full football scholarship is therefore;

p(A) ∩ p(B) = p(A) × p(B) = 0.75×0.93 = 0.6975

b. The probability that a randomly selected five star recruit will not select a university from one of the three best conferences = 1 - p(A) = 1 - 0.75 = 0.25

c. The events are independent as the given probability of occurrence of one event does not alter the probability of the other event

The events are inclusive events are exclusive events as P(A)and P(B) can take place simultaneously.

In simple linear regression, the predictor variable is the independent variable, which is used to predict the value of the dependent variable. It is also referred to as the explanatory variable, as it is used to explain the variability in the response variable.

For example, in a study that examines the relationship between the hours studied and exam scores, the predictor variable is the number of hours studied, and the dependent variable is the exam score.

The predictor variable is plotted on the x-axis, while the dependent variable is plotted on the y-axis in a scatter plot. The relationship between the predictor and the dependent variable is represented by a straight line, which is determined by the regression equation.

The slope of the line represents the change in the dependent variable for each unit change in the predictor variable.

In summary, the predictor variable is the variable that is used to predict or explain the changes in the dependent variable in simple linear regression.

The value of the piecewise function for f(3) is 4

From the question, we have the following parameters that can be used in our computation:

f(x) = 2x if x < 1

f(x) = 1/2x + 5/2 if x >= 1

The function f(3) implies that we make use of the function

f(x) = 1/2x + 5/2

This is because it is valid for x >= 1

substitute the known values in the above equation, so, we have the following representation

f(3) = 1/2 * 3 + 5/2

Answer:

Part A: Data set R

Part B: The correlation coefficient ranges from -1 to 1, where -1 represents a strong negative correlation and 1 represents a strong positive correlation. Data set R has a correlation coefficient of -.96, which has an absolute value that is closer to 1 than Data set Q's -.87, which means that it has a stronger linear relationship.

The data set R has a stronger linear relationship because the value of correlation coefficient is close to -1.

It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.

\(\rm r = \dfrac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{{[n\sum x^2- (\sum x)^2]}}\sqrt{[n\sum y^2- (\sum y)^2]}}\)

We have:

Correlation coefficient for data set Q = -0.87

Correlation coefficient for data set R = -0.96

The data set R has a stronger linear relationship because the value of correlation coefficient is -0.96 which is close to -1.

As we know the correlation coefficient varies between -1 to +1 when the value of correlation coefficient is close to -1 or +1 the relationship is strong.

Thus, the data set R has a stronger linear relationship because the value of correlation coefficient is close to -1.

The time Billy should get up to be right on time for school is 6:52 am.

The formula to calculate the time Billy should get up to be right on time for school is as follows: Time Billy Should Get Up = School Start Time - (Time to Get Dressed + Time to Eat Breakfast + Time to Walk to School). In this case, the formula is: Time Billy Should Get Up = 8:35 am - (32 minutes + 13 minutes + 17 minutes). In order to solve this equation, first we must convert the minutes to hours. 32 minutes is equal to 0.53 hours and 13 minutes is equal to 0.22 hours. 17 minutes is equal to 0.28 hours. Thus, the formula is: Time Billy Should Get Up = 8:35 am - (0.53 hours + 0.22 hours + 0.28 hours). Now, we can solve for the time Billy should get up. 8:35 am minus 0.53 hours is 7:42 am. Then, 7:42 am minus 0.22 hours is 7:20 am. Finally, 7:20 am minus 0.28 hours is 6:52 am. Therefore, the time Billy should get up to be right on time for school is 6:52 am.

#95141404393

The function that models the area A of a circle in terms of its circumference C is A = C²/(4π).

The formula for the circumference of a circle is C = 2πr or C = πd, where r is the radius and d is the diameter. To find a function that models the area A of a circle in terms of its circumference C, we can rearrange the formula for the circumference to solve for the radius: r = C/(2π). Substituting this value of r into the formula for the area, we get A = π(C/(2π))² = C²/(4π).

The whole values of a for which the solution of the equation ax = 6 is a = {1, 2, 3, 6}

The given equation is

ax = 6

Divide both side of the equation by a

ax / a = 6/a

Then the equation will be

x = 6/a

If the solution of the system should be a whole number, then the value of a should be a factor of the numerator 6.

If a is the factor of 6, then the only the result will be a whole number without any numerator

Then the factors of 6 are 1, 2, 3, 6

The correct variations of the formula for speed are:

m = 6d

d = m/6

6d = m

The formula for speed is distance divided by time. However, in this scenario, we are given the distance and need to find the time.

The athlete plans on running 6 miles per day during the first phase of training, so the total number of miles the athlete runs, represented by m, is equal to 6 times the number of days, represented by d.

Therefore, the correct equation that represents the relationship is:

m = 6d

This equation shows that the total number of miles, m, is directly proportional to the number of days, d, that the athlete runs.

Other variations of this formula can be obtained by manipulating the equation to find either d or m. For example, if we want to find the number of days, we can divide both sides of the equation by 6:

d = m/6

This equation shows that the number of days is equal to the total number of miles divided by 6.

Alternatively, if we want to find the total number of miles, we can multiply both sides of the equation by 6:

6d = m

This equation shows that the total number of miles is equal to 6 times the number of days.

(B) Usain Bolt's average speed in miles per hour was approximately 23.35 mph.

(A) Average speed = Distance / Time

Average speed = 200 meters / 19.30 seconds

Average speed = 10.36 meters per second

Therefore, Usain Bolt's average speed in meters per second was approximately 10.36 m/s.

(B) 1 mile = 2580 feet

Converting the distance from meters to miles:

Distance in miles = Distance in meters / (1 meter / 3.28 feet) / (1 mile / 5280 feet)

Distance in miles = 200 meters / 3.28 / 5280 miles

Time in hours = Time in seconds / (60 seconds / 1 minute) / (60 minutes / 1 hour)

Time in hours = 19.30 seconds / 60 / 60 hours

Average speed = Distance in miles / Time in hours

Average speed = (200 meters / 3.28 / 5280 miles) / (19.30 seconds / 60 / 60 hours)

Average speed = 23.35 miles per hour

O=A+4

while, A=A

,then using H^2= O^2 + A^2(The 2 are power,that is square)

7^2 = (A+4)^2 + A^2

49= (A+4)(A+4) + A^2

49=A^2 +4A+4A+16 + A^2

The ratio of apples to oranges is 3:2 or 3/2.

We have,

We can assume that,

The ratio of blue paint and yellow paint needed to make one liter of green paint:

= 3 : 5

We know that,

1 liter = 1000 ml

This means,

Blue paint = 3/8 x 1000 ml = 375 ml

Yellow paint = 5/8 x 1000 ml = 625 ml

We can now say that,

To make one liter of green paint:

Blue paint = 375 ml

Yellow paint = 625 ml

To make 40 liters of green paint.

Blue paint = 40 x 375 ml = 15,000 ml = 15 liters

Yellow paint = 40 x 625 ml = 25000 ml = 25 liters
