Answer:

x = 9.4868

Step-by-step explanation:

For this problem we can use the Pythagorean Theorem

Pythagorean theorem = [tex]a^2+b^2=c^2[/tex]

IN THIS CASE C = X

A and B are the side and base lengths of a right triangle.

C is the Hypotenuse side.

[tex]9^2+3^2=c^2[/tex]

Solve...

81 + 9 = [tex]c^2[/tex]

90 =[tex]c^2[/tex]

[tex]\sqrt{90}[/tex] = c

c = 9.4868

Answer:

75%

Step-by-step explanation:

The computation of the percent of the professional professors there are tenured is shown below;

Given that

academic professors A = 60%

professors  tenured P = 70%

professors at Paracelsus University = 90%

Based on the above information

As we know that 90% of the professors could be academic professors or tenured or both

so  here we can say that the percent of academic professors  is

= 60 + 70 - 90

= 40

Therefore professors  tenured will be

= 70 - 40

= 30

Now the percentage of professional professor that is tenured is

= 30 ÷ 40 × 100

= 75%

Answer:

4/3 x 5/8 is correct

Step-by-step explanation:

Answer: C 7/10 * 5/8

Step-by-step explanation:

4/3 * 5/8 = 20 / 24 = 5 / 6

3/2 * 5/8 = 15 / 16

7/10 * 5/8 = 35/80 = 7 / 16

9/7 * 5/8 = 45 / 56

5/8  = 10/16

7/16 < 10/16

7/16 < 5/8

Answer:

9 units is the answer.

Step-by-step explanation:

points are (-10,-4) and (-10,5)

Pythagorean theorem can be written as,

[tex]d=\sqrt{(x_2-x_1)^2 + (y_2-y_1)^2} \\\\d=\sqrt{(-10-(-10))^2 + (5-(-4))^2}\\\\d=\sqrt{(0)^2+(9)^2} \\\\d=\sqrt{81} \\\\d=9[/tex]

∴ d = 9 units

Answer:

Step-by-step explanation:

Parts + 3($40 labor)=183.30

parts + 120=183.30

parts=63.30 but it includes tax. To find costs of parts before tax you

63.30/1.055=60 so parts are $60

or to solve with one equation:

parts(1.055) + 3($40 labor) = 183.30

parts(1.055) + 120=183.30

parts(1.055)=63.30

Parts = 63.30/1.055

parts = 60

Answer:

12 ft

Step-by-step explanation:

From the question given above, the following data were obtained:

Angle θ = 41.5°

Opposite = 8 ft

Length of handrail =?

We can obtain the length of the handrail by calculating the Hypothenus. This can be obtained as follow:

Angle θ = 41.5°

Opposite = 8 ft

Hypothenus =?

Sine θ = Opposite /Hypothenus

Sine 41.5 = 8 / Hypothenus

0.6626 = 8 / Hypothenus

Cross multiply

0.6626 × Hypothenus = 8

Divide both side by 0.6626

Hypothenus = 8 / 0.6626

Hypothenus = 12 ft

Thus, the Lenght of the handrail is 12 ft

Answer:

answer is b.

Step-by-step explanation: use formula

V=1/3(hπr²)

so using this formula gives us 1275.62897 but rounded off gives us 1,275.63 ft3

ok the diameter is 21 3/4ft i converted it to a decimal, 21.75ft so to get the radius i 21.75ft/2= 10.875ft

ok to continue

V=1/3(hπr²)

V=1/3(3.14*10.875ft)h

V=1/3(118.265625ft)

V=1/3(118.265625 ft)10.3ft

V=1275.62897 which rounded=1,275.63 ft3

Answer:

pH = 6.1

Step-by-step explanation:

pH = -log[H]

pH = -log[8.1 x 10^-7]

pH ≈ 6.09

Therefore, option a, 6.1, is closest to this value and is the correct answer.

Answer:

0.9772 = 97.72% probability that the grade of a randomly selected students score is more than 60.

Step-by-step explanation:

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.

The average grade for an exam is 74, and the standard deviation is 7.

This means that [tex]\mu = 74, \sigma = 7[/tex]

What is the probability that the grade of a randomly selected students score is more than 60?

This is 1 subtracted by the pvalue of Z when X = 60. So

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

[tex]Z = \frac{60 - 74}{7}[/tex]

[tex]Z = -2[/tex]

[tex]Z = -2[/tex] has a pvalue of 0.0228

1 - 0.0228 = 0.9772

0.9772 = 97.72% probability that the grade of a randomly selected students score is more than 60.

The most common measures are mean, median, and mode. MIS. Measure ... For an even amount of data values - Calculate the mean of the two middle numbers. ... store had total sales of $436, $650, $530, $500,$650, $489, and $423 last week. ... would make the store's sales last week appear the most profitable? Explain.

The mean and the median of the data will be $525.43 and $500, respectively.

The mean is the straightforward meaning of the normal of a lot of numbers. In measurements, one of the markers of focal propensity is the mean. The normal is alluded to as the number-crunching mean. It's the proportion of the number of genuine perceptions to the absolute number of perceptions.

A retail store had total sales of $436, $650, $530, $500, $650, $489, and $423 last week.

Then the mean of the data will be

Mean = (436 + 650 + 530 + 500 + 650 + 489 + 423) / 7

Mean = $525.43

Arrange the data in ascending order, then we have

$423, $436, $489, $500, $530, $650, $650

Then the median of the data will be

Median = $500
