x = 1.67 hours is the nearest time when Plumer B becomes more expensive than plumber B.

The equation is the relationship between variables and is represented as y = ax+b is an example of a polynomial equation.

Let the hours be x and the hourly rate is y.
Now the data given in the table is calibrated into the equation.
The equation for A,
y = 15x + 35    - - - - - (1)
The equation for B,
y = 12x + 40    - - - - - - (2)

Solving equations 1 and 2
15x + 35 = 12x + 40
3x = 5
x = 5/3
x = 1.67 hour
Now put it on equation 2 and equation 1
y(B) = 12 * 1.68 + 40
y (B)= $60.1
y(A) = 12 *1.68 + 35
y(A) = $60.2


Thus, x = 1.67 hours is the nearest time when Plumer B becomes more expensive than plumber B.

Answer:

Step-by-step explanation:

1500(1.055)^7= 2182.02

Answer:

6.89

Step-by-step explanation:

Well, the number is smaller than 7 so it's 6 or less.

It's 7 when rounded up so it's got to be 6.__

The digit after 6 has to be even and has to be larger than 5 so it's either 6 or 8

The hundredths place digit is the greatest 1-digit odd number which is 9.

6.69 or 6.89 but since none of the digits can be repeated, it's 6.89

The geometric mean of the numbers is 5.38

Given the values a, b, c and d

The geometric mean of the values will be expressed as:

[tex]GM = (abcd)^{1/4}[/tex]

Given the values 4, 5, 6, and 7, the geometric mean will be expressed as:

[tex]GM = (4\times5\times6\times7)^{1/4}\\[/tex]

[tex]GM = (840)^{1/4}\\GM=\sqrt[4]{840} \\GM = 5.38[/tex]

As the problem states, the variable has a normal distribution, and thus, concepts of this distribution are used to solve this question.

Normal Probability Distribution

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

In a health club, research shows that on average, patrons spend an average of 46.2 minutes  on the treadmill, with a standard deviation of 4.8 minutes.

This means that [tex]\mu = 46.2, \sigma = 4.8[/tex]

Find the probability that randomly selected individual would spent  between 30 and 40 minutes on the treadmill.

This is the p-value of Z when X = 40 subtracted by the p-value of Z when X = 30.

X = 40

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{40 - 46.2}{4.8}[/tex]

[tex]Z = -1.29[/tex]

[tex]Z = -1.29[/tex] has a p-value of 0.0985

X = 30

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{30 - 46.2}{4.8}[/tex]

[tex]Z = -3.38[/tex]

[tex]Z = -3.38[/tex] has a p-value of 0.0004.

0.0985 - 0.0004 = 0.0981

Thus, 0.0981 = 9.81% probability that randomly selected individual would spent  between 30 and 40 minutes on the treadmill.

Answer:

4b³ + 11b² - 6b + 13

Step-by-step explanation:

Subtract like terms.

6b³ - 2b³ = 4b³

3b² - (-8b²) = 3b² + 8b² = 11b²

0 - 6b = -6b

8 - (-5) = 13

All together, the difference is 4b³ + 11b² - 6b + 13.

In functions; transformations are used to move lines, points, curves or shapes across the graph (i.e. up, down, right or left). After the transformation of [tex]f(x) = \log\ x[/tex], the resulting function is [tex]g(x) = 2\log\ (-x + 4) - 6[/tex]

Given that:

[tex]f(x) = \log\ x[/tex]

When translated 4 units left, the rule of translation is:

[tex](x,y) \to (x + 4,y)[/tex]

So, we have:

[tex]f'(x) = \log\ (x + 4)[/tex]

When translated 3 units down, the rule of translation is:

[tex](x,y) \to (x,y-3)[/tex]

So, we have:

[tex]f"(x) = \log\ (x + 4) - 3[/tex]

When reflected about the y-axis, the rule of reflection is:

[tex](x,y) \to (-x,y)[/tex]

So, we have:

[tex]f'"(x) = \log\ (-x + 4) - 3\\[/tex]

Lastly, when it is vertically stretched by 2; the rule is:

[tex](x,y) \to (x,2y)[/tex]

So, we have:

[tex]g(x) = 2[\log\ (-x + 4) - 3][/tex]

Open bracket

[tex]g(x) = 2\log\ (-x + 4) - 6[/tex]

Supplementary

Step-by-step explanation:

When two positive angles form a linear pair, meaning a straight line, they are supplementary.

Step-by-step explanation:

. The mean is less than the median.

The statement that is most likely correct for the negatively skewed data distribution given is: B. The mean is less than the median.

A negatively skewed data distribution has the tail to the left of the number line, and therefore its median is usually greater than its mean.

Negative skewed: Mean < Median < Mode

No skewed: Mean = Median = Mode

Positive skewed: Mean > Median > Mode

The dot plot shows a data distribution that is negatively skewed. Therefore, the statement that is most likely to be true is: B. The mean is less than the median.
