Answer:

a. The population is 100 college students.

b. The population is finite.

c. Two parameters and their values:

The total population size: 100

The sample size: 10

d. The sample is a group of 10 college students chosen from the population of 100.

e. Two corresponding statistics and their values:

The sample proportion: This is the proportion of individuals in the sample who have a certain characteristic (e.g. majoring in a certain subject). It is calculated by taking the number of individuals with the characteristic and dividing by the sample size. Its value would be different for each sample of size 10 taken.

The sample mean: This is the average of the measurements for the individuals in the sample. It is calculated by summing up the measurements and dividing by the sample size. Its value would be different for each sample of size 10 taken.

f. When another sample of size 10 is taken, the population and its size remains fixed but sample proportion and sample mean would change.

Step-by-step explanation:

The speed at which Shola climbed is 5 m/s and the time taken by Shola to reach the edge is 6 seconds.

According to the question

Given:

The total distance traveled by Shola = 30 meters

He covered a total distance of 22.5 meters  (i.e. 30 meters - 7.5 meters) in 4.5 seconds.

His speed is thus 5 m/s since speed is equal to both distance and time.

Since he has 7.5 meters to cover, the remaining distance,

Therefore, the time it took him to travel the distance was 7.5/5, or 1.5 seconds.

Consequently, the total amount of time needed to go 30 meters,

T=4.5+1.5=6, or one second.

Palisade Bakery is a better buy than Union City Bakery.

To determine which bakery has the better buy, we need to calculate the cost per muffin at each bakery. It is determined by dividing the total cost by total number of muffins. Assuming one batch has ten muffin as not mentioned.

Union City Bakery: $10.00 / 3 batches = $3.33 per batch (approx)

= $3.33/ 10

= $0.33 per muffin

Palisade Bakery: $6.25 / 20 muffins = $0.31 per muffin

Based on this calculation, Palisade Bakery has the better buy as each muffin costs $0.31, which is cheaper than the cost per muffin at Union City Bakery, which is approximately $0.33 per muffin.

For the given stem and leaf plot, the range of data is option C: 25.

What is stem and leaf plot?

A stem and leaf plot, also known as a stem and leaf diagram, is a way to arrange data so that it is simple to see how frequently various sorts of values occur. It is a graph that displays ordered numerical data. A stem and a leaf are divided into each piece of data.

The stem and leaf plot for data is given.

The range of data is defined as a measure of the difference between the maximum value of data and the minimum value of data.

From the stem and leaf plot the maximum value obtained is = 35

From the stem and leaf plot the minimum value obtained is = 10

The range is then calculated as -

The solution of the system of equations:

-2x - 10y = -2

-4y = x

is the point (-4, 1).

Here we want to solve the system of equations below:

-2x - 10y = -2

-4y = x

By the substitution method, to do so, we need to isolate one of the variables in one of the equations and then replace that in the other equation.

We can see that x = -4y is already isolated on the second equation, then we can replace this on the first one to get:

-2*(-4y) - 10y = -2

We can solve this for y.

8y - 10y = -2

-2y = -2

y = -2/-2 = 1

And thus, the value of x is:

x = -4y

x = -4*1 = -4

The solution of the system is (-4, 1).

This problem can be solved used linear equations. Here there are two variables, number of students and number of adults. After calculations we get the number of students attended the play is 50.

Lets consider the number of students is x and number of adults is y.

Total tickets sold = 300

    x + y = 300  ------------ equation 1

The amount of total tickets sold is 3000.

Amount sold to students = 5x

Amount sold to adults = 11y

  So, 5x+11y =3000 ----------- equation 2

Equating the x term for equation 1

 Multiplying both sides with 5

 5 (x+y) = 5 × 300

 5x + 5y = 1500 ---------- equation 3

Subtracting equation 3 from equation 2

   5x + 11y = 3000

-  ( 5x + 5y = 1500)

    6y = 1500

    y = 1500/6 = 250

Number of adult attended = 250

From equation 1, x+y = 300

Substituting the value of y

                x + 250 = 300

                    x    = 300-250 = 50

So number of students attended is 50

Take care to properly set up your equations. The $3,000 is the sum of total money from student tickets and total money from the adult tickets.

Answer:  1.25 or 1, 1/4

The correct answer for equivalent interest rate and no. of times will the money be compounded is C) 1.5% and 16 times respectively.

The annual interest rate of 6% is equivalent to a quarterly interest rate of 6% / 4 = 1.5%. The money will be compounded quarterly, so it will be compounded 16 times in total over 4 years.

Compound interest is computed as interest on the initial principal plus any accrued interest from prior periods. Money multiplies more quickly thanks to compounding, and the more compounding periods there are, the higher the compound interest will be.

The standard error of the mean for these data is 13.14 pounds..

The standard error of the mean (SEM) is a measure of the variability of the sample mean. It is calculated as the standard deviation of the sample divided by the square root of the sample size.

To find the SEM for the given data, we first need to calculate the sample mean:

(160 + 215 + 195) / 3 = 190

Then we need to calculate the deviation of each value from the mean:

160 - 190 = -30

215 - 190 = 25

195 - 190= 5

Next, we need to square these deviations:

(-30)² = 900

25² = 625

5² = 25

Next, we need to calculate the variance:

(900 + 625 + 25) / 3 = 516 2/3

Then we need to calculate the standard deviation:

√(516 2/3) = 22.73

Finally, we can calculate the standard error of the mean:

22.73 / √(3) = 13.14

So, the standard error of the mean for these data is 13.14 pounds.

The area in square meters will the oil slick cover is 9.5×10⁶ m².

15 barrels of diesel spilt into the ocean, where each barrel contains 42 gallons. Thereby the total volume of the oil spilt by 15 barrels is calculated as follows:

The total volume of the oil spilt by 15 barrels = 15× 42 gallons.

=630 gallons

1 gallon = 3.78541 liters

Volume in L = 630 gallons × 3.78541 liters/ 1 gallon

= 2384.8083 L

1 L = 10⁻³ m³

2384.8083  L = 2384.8083 × 10⁻³ m³

= 2.3848083 m³

The area covered by the oil spill has to be determined, where the thickness of the oil spill is given to be 2.5×10² nm.

1 nm = 10⁻⁹ m

Thereby, 2.5×10² nm = 2.5×10²×10⁻⁹ m

= 2.5×10⁻⁷ m

Area (m²) = volume (m³)/thickness (m)

Determine the number of pieces of type (a) detergent.

Divide both sides by 9.00:

Determine the number of pieces of type (b) detergent.

Divide both sides by 7.00:

Since we cannot sell partial pieces, the number of pieces of type (b) detergent must be rounded up to 26 pieces.
