Step-by-step explanation:

The volume of the sphere with radius 5 yd rounded to the nearest tenth is 523.3 yd³.

The volume of a sphere is expressed as;

V = 4/3 × π × r³

Where r is radius and constant pi π = 3.14.

Given the data in the question;

To find the volume of the sphere, plug the given value into the above formula and simplify.

V = 4/3 × π × r³

V = 4/3 × 3.14 × ( 5 yd )³

V = 4/3 × 3.14 × 125 yd³

V = 523.3 yd³

Therefore, the volume of the sphere is 523.3 yd³.

Answer: The Cartesian form of a complex number is the expression of the number in the form of x + yi, where x and y are real numbers and i is the imaginary unit.

The Cartesian form of (5i - 3) is 0 + (5i - 3).

Step-by-step explanation:

The straight line distance is 13 blocks.

We know that we can be able to obtain the straight line distance by looking at the information that has been provided by the question. We are told in the question that; you go north 3 blocks turn East and go blocks, and go 7 blocks turn South turn West and go 3 blocks.

We know that the distance is not a vector quantity as such, we do not look at the direction of the movement. We would only be concerned about the magnitude of the distance.

Thus we have the straight line distance as; 3 + 7 + 3 = 13 blocks

The length of the fence that Winston installs is 200 yards

An equation is an expression that contains numbers and variables linked together by mathematical operations of addition, subtraction, multiplication, division and exponents. An equation can either  be linear, quadratic, cubic, depending of the degree of the variable.

Winston installs a fence post every eight yards after the first post he installs 25 more, therefore:

The length of the fence = 8 yards * 25 post = 200 yards

Answer: Given f(x) = -4x + 9 and g(x) = x^2 - x - 10, the composition of functions fog(x) is defined as fog(x) = f(g(x)).

To find the value of fog(5), we need to evaluate g(5) first:

g(5) = 5^2 - 5 - 10 = 20

Now that we have g(5) = 20, we can substitute it into f(x) to find fog(5):

fog(5) = f(g(5)) = f(20) = -4 * 20 + 9 = -79

So, the value of fog(5) is -79.

Step-by-step explanation:

top = bottom so 4x-4y = 3x+5y so x = 9y

left = right so 2-2y = x-3y so x= y+2

so 9y = y+2

8y = 2

y= 0.25

x=2.25

so just add them all up

2*(4x-4y) + 2*(2-2y )

= 8*(x-y)+4*(1-y)

=16+4*0.75

Answer:

Let's call the growth rate of the tomato plant "g". We know that the height difference between the tomato plant and the bean plant decreases by 0.1 cm per day, so we can write the following equation:

1.5 - 0.85 - (10 * g) = 0

Solving for g:

g = (1.5 - 0.85) / 10 = 0.065 cm/day

So the tomato plant grows at a rate of 0.065 cm per day, and will reach the height of the bean plant in no more than 10 days.

The tomato plant will grow 0.165 cm per day.

Solution:

Given,

Height of bean plant = 1.5 cm

Height of tomato plant = 0.85 cm

The growth rate of bean plant = 0.1 cm/ day

The bean plant will grow 1.5 + (0.1* 10) in 10 days = 2.5 cm

So, the tomato plant will have to grow (2.5 - 0.85) cm in 10 days = 1.65 cm

Since, the tomato plant will grow steadily,

Hence, 1.65/ 10 = 0.165

Therefore, the tomato plant will grow at a rate of 0.165 cm per day

The actual food is 115% of the budgeted food.

The percentage is defined as a ratio expressed as a fraction of 100.

The data is given in the question, as follows:

Budgeted: 200

Actual: 230

To determine the percentage of the budgeted food that is the actual food, we can divide the actual amount by the budgeted amount and multiply by 100.

Percentage = (Actual / Budgeted) * 100

Percentage = (230 / 200) x 100

Percentage = 1.15 x 100

Apply the multiplication operation, and we get

Percentage = 115%

So, the actual food is 115% of the budgeted food.

Answer:

1a. The null hypothesis in this setting would mean that the proportion of students who completed their math homework is equal to or greater than 75%.

1b. The p-value represents the probability of observing a sample proportion as extreme as or more extreme than the sample proportion observed (68%), given that the null hypothesis is true. In this case, the p-value of 0.1265 indicates that there is a 12.65% chance of observing a sample proportion as extreme or more extreme than 68%, assuming the true proportion is equal to or greater than 75%.

1c. At the alpha = 0.05 significance level, we reject the null hypothesis if the p-value is less than 0.05. In this case, the p-value of 0.1265 is greater than 0.05, meaning we fail to reject the null hypothesis. Therefore, at the alpha = 0.05 significance level, we cannot conclude that less than 75% of students completed their math homework.

50 meters in feet is 164.042 feet

In order to convert meters to feet we would have to cross multiply

That is. one meter is given as 3.28084 feet

We are to convert 50 meters to feet, hence we would have:

If 1 meter = 3.28084

50 meters = ?

When we cross multiply, we would have

? = 3.28084 * 50 meters

? = 164.042

Hence the amount of 50 meters in feet is given as 164.042 feet

It is possible that the standard deviation is greater than the mean for a list of positive numbers.

What is standard deviation?

The standard deviation is a metric that reveals how much variance from the mean there is, including spread, dispersion, and spread. A "typical" variation from the mean is shown by the standard deviation. Because it uses the data set's original units of measurement, it is a well-liked measure of variability.

Take into consideration, the list of numbers -

1,2,3,4,5,20

The mean formula is - Number of observations / Total observations.

Substitute the values in the equation -

Mean = 1 + 2 + 3 + 4 + 5 + 20 / 6

Mean = 35 / 6

Mean (x') = 5.833

The number of observations is n = 6

The variance is the sum of squared deviations from the mean divided by

n−1.

The standard deviation is the square root of the variance -

s = {√(1 - 35/6)² + .... + (20 - 35/6)²} / (6-1)

s = 7.0828

Therefore, the standard deviation is higher than the mean.

Also cumulative frequency in the table form mentioned here. This can be solved using the concept of frequency distribution.

Tables or charts of frequency distributions are used to represent them. Frequency distributions can display the proportion of observations or the actual number of observations that fall inside each range. The distribution is known as a relative frequency distribution in the latter case.

Relative frequency distributions and cumulative frequency distributions are the two primary forms of frequency distributions utilised in data analysis. Both depend on frequency, which is the amount of times something happens inside a specific data set in descriptive statistics.

The complete question is as follows:

Answer:

Abdiel's total would be $23.22, which is the answer choice C.

Step-by-step explanation:

The total cost of Abdiel's order would be calculated as follows:

Calculate the tip before the discount: $21.50 x 20% = $4.30

Add the tip to the subtotal: $21.50 + $4.30 = $25.80

Calculate the discount: $25.80 x 10% = $2.58

Subtract the discount from the total cost: $25.80 - $2.58 = $23.22

So, Abdiel's total would be $23.22, which is the answer choice C.

Answer:

x=90° (given)

54°+90°+z=180°

144°+z=180°

z=180°-144°

z=30°

The explicit rule for the g(x) is g(x) = 54000 + 6000x

The definition of the function is given as

Initial = 60000

And the table of values

The definitions from the table imply that we simply add 6000 to the previous term to get the current term

This means that

Common difference, d = 6000

The sequence is then represented as

f(x) = a + (x - 1)d

So, we have

f(x) = 60000 + (x - 1) * 6000

Evaluate

f(x) = 54000 + 6000x

Hence, the equation is f(x) = 54000 + 6000x
