Answer:

30%

Step-by-step explanation:

The two outcomes (can work the problem and can't work the problem) are complementary.

In probability theory, the complement of any event A is the event [not A], i.e. the event that A does not occur. The event A and its complement [not A] are mutually exclusive and exhaustive.

Complementary events are two outcomes of an event that are the only two possible outcomes.

Complementary outcomes add to 1 or 100%.

100 - 70 = 30.

The amount received from loans as a number in millions is 242,700 million rand.

Deducing value A requires computation of collective income sources, for which the following summation suffices:

Total Income = Tax + Loans + ASC + QP + Other income + Non-tax income = 1370 + 242.7 + 180.3 + 31.5 + A + 0 = 1825.5 + A

In this context, it follows that A amounts to (1825.5 - 1370 - 242.7 - 180.3 - 31.5) = 0 million rand.

Conversely determining missing value B necessitates subtraction of total expenditure from accumulated revenue, giving rise to the subsequent formula:

Total Income - Total Expenditure = B

(1825.5 - 112.7 - 278.4 - 262.4 - 222.6 - 211.0 - 209.2 - 208.5 - 202.2 - 0) = B

Following calculation, B equates to -77.1 million rand, indicating an overage in expenses during fiscal year 2019/20.

Both sides of the equation simplify to a, and we can conclude that min(a, min(b, c)) = min(min(a, b), c) is true for all real numbers a, b, and c where a is the smallest.

One way to do this is through mathematical induction, which involves proving a statement for a specific set of values and then showing that it holds true for all other values. In this exercise, we will apply this method to prove two statements involving integers and real numbers.

Statement involving integers:

The given statement is n² + 1 ≥ 2n, where n is an integer in the range [1, 4]. In order to prove this statement, we need to verify it for all values of n in this range. We start with n = 1, which gives us 1² + 1 ≥ 2(1), or 2 ≥ 2. This is true, so we move on to n = 2, which gives us 2² + 1 ≥ 2(2), or 5 ≥ 4. This is also true. Continuing in this manner, we can verify that the statement is true for all values of n in the given range. Therefore, we can conclude that n² + 1 ≥ 2n is true for all integers in the range [1, 4].

Statement involving real numbers:

The given statement is min(a, min(b, c)) = min(min(a, b), c), where a, b, and c are real numbers and we assume that a is the smallest of the three. To prove this statement, we start with the left-hand side and simplify it using the assumption that a is the smallest real number:

min(a, min(b, c)) = min(a, b) if a ≤ b, otherwise min(a, b) = a

= min(min(a, b), c) if a ≤ min(a, b), otherwise min(min(a, b), c) = a

Next, we move on to the right-hand side of the equation and simplify it:

min(min(a, b), c) = min(a, c) if a ≤ c, otherwise min(a, c) = a

Since we assumed that a is the smallest real number, we know that a ≤ b and a ≤ c.

Step-by-step explanation:

Answer:

3. b. y = ⅝x - ½

4. b. y = ⁵/2x + ½

Step-by-step explanation:

Recall: Slope-intercept form of equation is given as y = mx + b

Where, m = slope, and b = y-intercept.

To find the equation of each line, we must first find the b and m of each graph.

3. Slope of the line using two points on the line, (4, 2) and (-4, -3):

Slope = change in y/change in x = (-3 - 2)/(-4 - 4) = -5/-8 = ⅝

Slope (m) = ⅝

To find y-intercept (b), substitute m = ⅝, and (x, y) = (4, 2) into y = mx + b. Thus:

2 = ⅝(4) + b

2 = ⁵/2 + b

2 - ⁵/2 = b

b = (4 - 5)/2

b = -½

To write the equation, substitute m = ⅝ and b = -½ into y = mx + b

y = ⅝x + (-½)

y = ⅝x - ½

4. Slope of the line using two points on the line, (1, 3) and (-1, -2):

Slope = change in y/change in x = (-2 - 3)/(-1 - 1) = -5/-2 = ⁵/2

Slope (m) = ⁵/2

To find y-intercept (b), substitute m = ⁵/2, and (x, y) = (1, 3) into y = mx + b. Thus:

3 = ⁵/2(1) + b

3 = ⁵/2 + b

3 - ⁵/2 = b

b = ½

b = ½

To write the equation, substitute m = ⁵/2 and b = ½ into y = mx + b

y = ⁵/2x + ½

Answer:

b. 0.08x + 20

Step-by-step explanation:

its B because the price goes up $40 every 500 KW's so

40 divided by 500 = 0.08

The expression used to calculate Naomi's electricity cost after using x kilowatt hours is 0.08x+20. Therefore, option B is the correct answer.

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.

From the graph we have, (500, 60), (1000, 100), (1500, 140) and (2000, 180).

We know that, slope of a line is Slope=(y2-y1)/(x2-x1)

= (100-60)/500

= 40/500

= 0.08

Substitute m=0.08 and (x, y)=(500, 60) in y=mx+c, we get

60=0.08(500)+c

60=40+c

c=20

Substitute m=0.08 and c=20 in y=mx+c, we get

y=0.08x+20

The expression used to calculate Naomi's electricity cost after using x kilowatt hours is 0.08x+20. Therefore, option B is the correct answer.

95% confidence interval for the ratio of medians is a range of values that we are confident contains the true population ratio, with a specified level of confidence.

A confidence interval is a range of values that we are confident contains the true population parameter, with a specified level of confidence. In this case, we are looking at the ratio of medians in the Verizon data and finding a 95% confidence interval for the ratio.

Let's say the sample median for the first data set is M1 and the sample median for the second data set is M2. The standard error for M1 and M2 can be calculated using the formula for the standard error of the median.

Next, we use the formula for a confidence interval for the ratio of medians:

=> (M1/M2) +/- (Z * SE(M1/M2)),

where Z is the critical value from a standard normal distribution for a 95% confidence level.

The percent bias is the difference between the estimated value and the true value, divided by the true value and expressed as a percentage. In this case, we will calculate the percent bias of the confidence interval for the ratio of medians relative to the standard error.

Finally, we compare the results for the ratio of medians with the results for the ratio of means. This comparison can give us an idea of the difference in the level of accuracy and precision between the two estimates.

The focal length of the parabola whose coefficient a is equal to 9, is 1/36.

What is focal length?

In a two-dimensional plane, a parabola is a curve that is symmetrical about the axes, passes through the vertex, and is perpendicular to the directrix. In other words, the locus of points that are equally spaced apart from the directrix and the fixed point, let's call it focus, is a parabola. The distance along the axis of symmetry from the vertex to the focus of the parabola is known as its focal length.

The focal length of a parabola is calculated as c' = 1/4a

In the given question, c' is the focal length and the coefficient a is the general quadratic equation and a=9.

Substituting the above values, in the focal length equation, we get,

c' = 1/(4*9)

⇒ c' = 1/36

Hence, the focal length of the parabola whose coefficient a is equal to 9, is 1/36.

Step-by-step explanation:

The sample size for the Gallup poll is 1,627 adults. The 95% confidence interval for those who say they felt fully engaged with their mortgage provider is approximately 22.0% (rounded to 1 decimal place).

To calculate the 95% confidence interval, we need to consider the margin of error. The margin of error is given as 2.5%, which means that we need to account for plus or minus 2.5% around the observed proportion of 22%.

First, let's calculate the margin of error:

Margin of Error = 2.5% of 22% = 0.025 * 22% = 0.0055

Next, we can calculate the lower and upper bounds of the confidence interval:

Lower Bound = 22% - Margin of Error = 22% - 0.0055 = 21.995% ≈ 22.0%

Upper Bound = 22% + Margin of Error = 22% + 0.0055 = 22.005% ≈ 22.0%

Therefore, the 95% confidence interval for those who say they felt fully engaged with their mortgage provider is approximately 22.0% (rounded to 1 decimal place).
