Answer: 1.1. The donation per learner cannot be determined from the given table.

1.2. TABLE 1: INCOME IN RANDS OF FUNDRAISING

Number of learners that paid Income (R)

1 200

1.3. To calculate the missing value A, we need to add up all the given incomes and subtract it from the total income for 45 learners, which is 45 x A. Then we can solve for A:

Total income = 200 + 150 + 10(2,000) + 20(45) + A + 4,000 + 9,000

Total income = 45A

45A = 25,150

A = 558.89

Therefore, the missing value A is R558.89.

1.4. The dependent variable in the table is the income received from fundraising.

To find the ratio of income received from 10 learners to income received from 45 learners, we need to divide the income received from 10 learners by the income received from 45 learners and simplify the fraction:

Income from 10 learners = R1,100 (since each learner donates R110)

Income from 45 learners = R215

Ratio = Income from 10 learners : Income from 45 learners

= 1,100 : 215

= 20 : 3 (in its simplest form)

The total number of learners enrolled at the school is 1,100. If 80% of the learners paid, then the number of learners who paid is:

80% of 1,100 = 0.8 x 1,100 = 880 learners

The minimum income that the school can raise if 80% of the learners paid is when each of the 880 learners paid the minimum donation, which is R150:

Minimum income = 880 x 150 = R132,000

Since R132,000 is less than R170,000, the SGB chairperson's statement is not valid.

Step-by-step explanation:

The average number of calendars sold per week by the 3rd period class during the four-week challenge is 30.

If we know the total number of calendars sold by the class during the challenge, we can use this information to find the value of x. Let's say that the total number of calendars sold by the class during the challenge is 120.

To find the average number of calendars sold per week, we can set up an equation:

x * 4 = 120

Here, x represents the average number of calendars sold per week, and 4 represents the number of weeks in the challenge. The product of x and 4 gives us the total number of calendars sold during the challenge, which we know is 120.

To solve for x, we can divide both sides of the equation by 4:

x = 120/4

x = 30

If Idil drove 12 miles in 1/5an hour on average, then she drove at an average speed of 60 miles per hour.

To calculate the average speed of Idil's car in miles per hour, we need to divide the distance she drove (12 miles) by the time it took her to drive that distance (1/5 hour):

Average speed = distance ÷ time

Average speed = 12 miles ÷ (1/5) hour

To divide by a fraction, we can multiply by its reciprocal, so:

Average speed = 12 miles × 5/1 hour

Average speed = 60 miles per hour

Therefore, Idil drove at an average speed of 60 miles per hour.

The probability that a truck drives between 99 and 128 miles in a day is 0.7734 rounded to four decimal places.

Standard deviation is a statistical measurement that depicts the average deviation of each value in a dataset from the mean value. It tells you how much your data deviates from the mean value. It represents the typical variation between the mean value and the individual data points.

The formula for the probability that a truck drives between 99 and 128 miles in a day is:

[tex]Z = (X - \mu) /\sigma[/tex]

where, X is the number of miles driven per day; μ is the mean of the number of miles driven per day; σ is the standard deviation of the number of miles driven per day. The value of Z for 99 miles driven per day is:

[tex]Z = (99 - 120) / 11 = -1.91[/tex]

The value of Z for 128 miles driven per day is:

[tex]Z = (128 - 120) / 11 = 0.73[/tex]

Using a standard normal distribution table or calculator, the probability of a truck driving between 99 and 128 miles per day is:

[tex]P(-1.91 < Z < 0.73) = 0.7734[/tex]

Answer: 240 miles in 2 hours

Step-by-step explanation:

we know the car is traveling 60 km per half hour (30 minutes)

so to find km per hour, multiply both by 2.

the rate of speed is 120 miles per 60 minutes (1 hour)

multiply 120 mph by the 2 hours given = 240 miles in 2 hours

Answer:

240 km in 2 hours

Step-by-step explanation:

If the car travels 60 km in 30 minutes, then its speed can be calculated as follows:

Speed = distance ÷ time

Speed = 60 km ÷ (30 minutes ÷ 60) = 120 km/hour

Since the car is traveling at a constant speed, we can use the formula:

Distance = Speed × Time

To find how far the car will travel in 2 hours, we can substitute the values we have found:

Distance = Speed × Time

Distance = 120 km/hour × 2 hours

Distance = 240 km

Therefore, the car will travel 240 km in 2 hours if it continues at the same constant speed.

The population of the country was 259 million in 1982 and the continuous exponential growth rate was estimated at 1.6% per year. Assuming that the population of the country continues to follow an exponential growth model, Rounding off the answer to one decimal place, the approximate population in 1992 is 348.2 million.

How to calculate the projected population? We are given, Population in 1982 = 259 millionTime taken = 10 years rate of growth = 1.6% = 0.016 (expressed as a decimal)The formula for exponential growth can be written as; Population = P0ert where, P0 is the initial population, e is the natural logarithmic base, r is the rate of growth and t is the time period We are required to find the projected population in 1992, which means the time period is 10 years (from 1982 to 1992).

Hence, substituting the given values in the formula, we get; P = 259e 0.016 × 10P = 259e0.16P = 259 × 1.185P = 307.215 million  Hence, the projected population in 1992 is 307.215 million (rounded off to 1 decimal place, it is 307.2 million).

The expression 1/5 + -4/5 has plotted on the number line

To model 1/5 + (-4/5) on a number line, we can start by placing a point at 0 on the number line. Then we can represent 1/5 by placing another point to the right of 0, one-fifth of the distance from 0 to 1. We can represent -4/5 by placing a point to the left of 0, four-fifths of the distance from 0 to -1.

To add these two points together, we start at the point representing 1/5 and move four-fifths of the distance towards the left, since -4/5 is negative. The resulting point represents the sum of 1/5 and -4/5.

To solve this problem algebraically, we can add the two fractions together by finding a common denominator:

Answer:

To find out how many bushes are in each row, we need to use the information given in the problem. We know that there are a total of 15 bushes at the entrance to the park, and the garden contains the same number of bushes in each row. Therefore, we can subtract the 15 bushes at the entrance from the total number of bushes in the garden to find out how many bushes are in the rows:

Total number of bushes in the garden = Number of rows × Number of bushes in each row

Total number of bushes in the garden = 4 × Number of bushes in each row

So, we can write:

4 × Number of bushes in each row - 15 = Number of bushes in the garden

We are not given the total number of bushes in the garden, but we can use algebra to solve for the number of bushes in each row:

4 × Number of bushes in each row - 15 = Number of bushes in the garden

4 × Number of bushes in each row - 15 = 35 (since there are 15 bushes at the entrance to the park, the total number of bushes in the garden is 35)

4 × Number of bushes in each row = 50

Number of bushes in each row = 50 ÷ 4

Number of bushes in each row = 12.5

Since the number of bushes in each row must be a whole number, we can round up to get:

Number of bushes in each row = 13

Therefore, each row in the garden has 13 azalea bushes.

The dollar interval that would give a probability of 0.500 is X ± $8.47.

To determine the dollar interval that would give a probability of 0.500, we need to calculate the confidence interval using the formula:

Confidence interval = X ± Zα/2 × σ/√n

where:

X = sample mean

Zα/2 = Z-score for the desired level of confidence (in this case, 0.500 corresponds to a Z-score of 1.96)

σ = population standard deviation

n = sample size

Substituting the given values, we have:

Confidence interval = X ± 1.96 × 80/√64

Confidence interval = X ± 19.6

Since we want a probability of 0.500, we need to find the z-scores that correspond to the middle 50% of the normal distribution. Using a standard normal table, we can find that the z-scores are approximately -0.6745 and +0.6745.

Therefore, the confidence interval that will give a probability of 0.500 is:

X ± 0.6745 × 80/√64

X ± 8.47
