If mQOS = 46, and mPOR = 61
and mPOQ = 28, what is mROS?

Answer: 14 and 3.5

Step-by-step explanation:

Answer:

We conclude that:

csc (U) = 26 / 24        

Step-by-step explanation:

Given

To determine

csc (U) = ?

Using the trigonometric ration

sin Ф = opposite / hypotenuse

substituting Ф = U, opposite = 24, hypotenuse = 26

sin (U) = 24/26

We know that: csc (U) = [1 ] / [sin(U)]

Therefore,

csc (U) = [1 ] / [sin(U)]

            = 26 / 24

Therefore, we conclude that:

csc (U) = 26 / 24        

Answer:

x = -3  and x = - 3/4

Step-by-step explanation:

We can use the quadratic formula to solve for x, considering a = 4 , b = 15, and c = 9:

[tex]x=\frac{-b+/- \sqrt{b^2-4a*c} }{2*a} \\x=\frac{-15+/- \sqrt{(-15)^2-4*4*9} }{2*4}\\x=\frac{-15+/- \sqrt{81} }{8}\\x=\frac{-15+/- 9 }{8}=-\frac{6}{8} \,\,or\,\,-\frac{24}{8} \\x=-\frac{3}{4}\,\,or\,\,x=-3[/tex]

Answer:

One-sixth or 1/6

Step-by-step explanation:

A probability density curve satisfies several rules: It never goes below the horizontal axis, i.e. it's never negative. ... The chance of the quantity falling between a and b is the area under the curve between the point a and b.

The height of density curve is 1/6. Therefore, option B is the correct answer.

In probability theory, a probability density function, or density of a continuous random variable, is a function whose value at any given sample in the sample space can be interpreted as providing a relative likelihood that the value of the random variable would be close to that sample.

A density curve is always on or above the horizontal axis. The area underneath a density curve is exactly 1. The area under a density curve and above any range of values is the relative frequency of all observations that fall in that range.

The curve will never dip below the x ≥ Height>0

Area under the curve=Area of a rectangle with length=height of curve width=6

=Height of curve × 6

Area under the curve = 1

⇒ Height of curve × 6=1

=1/6

The height of density curve is 1/6. Therefore, option B is the correct answer.

Complete question :

A college football coach wants to know if the is a correlation between his players' leg strength and the time it takes for them to sprint 40 yards. he sets up the following test and records the data:

Every day for a week, he counts how many times each player can leg press 350 pounds. The following week, he has each player sprint 40 yards every day. The tables shows the average number of leg-press repetitions and the average 40-yard dash time (in seconds) for seven randomly selected players. What is the equation of the line of best fit? How many seconds should he expect a player to take to run 40 yards if that player can do 22 leg-press repetitions?

Using a regression calculator :

The equation of line of best fit is :

ŷ = 0.1073X + 4.5365

Slope or gradient = 0.1073

Intercept = 4.5365

X = independent or predictor variable (leg press)

Y = predicted variable (40 yard dash)

B)

X = 22

Y = 0.1073(22) + 4.5365

Y = 6.8971

Y = 6.9

Answer:

d. A good line of best fit is y= 0.36x -20.15 because this is what the regression calculator returns if all the data except the point (86, 2) are entered. :)

2 fractions are equal

Step-by-step explanation:

We say that two quantities are proportional if one is always the same multiple of the other.

Say a recipe calls for 2 cups of flour to 3 eggs. That proportion, 2 cups flour : 3 eggs, will always stay the same, no matter how many serving we make. If we make 2 servings, we'd double to 4 cups and 6 eggs, but that wouldn't change the proportion. After all,

Answer:

its C. all of the sea urchin in the entire ovean is the most likely to be the population of interest

The population of interest will most likely be option B. all of the sea urchins near the plant.

The term 'population of interest' refers to the group or number from which inference is made or done for research purposes. And from this group, the researcher will try to draw conclusions from his/her study.

For the marine biologists to determine the extent of the factory's effect on the sea urchins, they would consider or take the sea urchins near the factory population as the population of interest. Thus, the correct answer is option B.

Answer:

61.16667 ; (58.958, 63.375)

Step-by-step explanation:

Given the data :

72,51, 67, 68, 61, 69, 58, 56, 60, 56, 66, 61, 60, 59, 59, 54, 58, 53, 68, 63, 57, 62, 63, 64, 56, 62, 58, 67, 57, 70

Standard deviation, σ = 5.3

Sample size, n = 30

The point estimate of the population mean:

Mean, m = Σx/n

Σx = 1835 ; n = 30

m = 1835 / 30

m = 61.16667

Confidence interval :

m ± Tn-1,α/2 * σ/sqrt(n)

61.16667 ± T30-1,0.03/2 * 5.3/sqrt(30)

61.16667 ± T29,0.015 * (5.3/sqrt(30))

61.16667 ± 2.282175 * (0.9676431)

Lower bound = 61.16667 - 2.20833 = 58.95834

Upper bound = 61.16667 + 2.20833 = 63.375

(58.958, 63.375)

Answer:

a = -2

Step-by-step explanation:

The graphs of the lines would have to be parallel.  So they must have the same slope.   2x + y = -1 changed to slope-intercept form is y = -2x - 1.  Therefore, the slope of that line is -2.   y = ax is in slope-intercept form where the slope is a.  So, a must equal -2.

Answer: The project is 7/8 painted.

Step-by-step explanation: Add 1/8 to 3/4 for the total.

Use the least common denominator, /8

3/4 is equivalent to 6/8.

6/8 + 1/8 = 7/8

Step-by-step explanation: To find how much of the wall Maya painted, we will add the two fractions. Let's do it step-by-step.

1. These fractions have unlike denominators, to make them alike, we have to find the LCD (Least Common Denominator).

3/4 = 6/8

1/8 = 1/8

Note: What you did to the bottom, you do to the top.

1a. I multiplied 2 by 3 and 4 to get 6/8.

1b. I multiplied 1 by 1 and 8 to get 1/8.

2. Since we have like denominators, we can add!

[tex]Solve:\frac{6}{8} +\frac{1}{8} = \frac{7}{8}[/tex]

Therefore, your answer is 7/8. The fraction don't need to be reduced to lowest terms.
