Answer:

D

Step-by-step explanation:

The amount of oil and natural gas a given region produces is not always proportionate to the size of its proven reserves. For example, the Middle East contains approximately 50 percent of the world’s proven reserves but accounts for only about 30 percent of global oil production (though this figure is still higher than in any other region). The United States, by contrast, lays claim to less than 2 percent of the world’s proven reserves but produces roughly 16 percent of the world’s oil.

Answer:

0.2916 = 29.16% probability that one of them is pre-diabetic

Step-by-step explanation:

For each adult, there are only two possible outcomes. Either they have blood chemistry parameters consistent with a diagnosis of a pre-diabetic condition, or they do not. Each volunteer in independent of other volunteers. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

10% of the adult population has blood chemistry parameters consistent with a diagnosis of a pre-diabetic condition.

This means that [tex]p = 0.1[/tex]

Of four volunteer participants in a health screening study, what is the probability that one of them is pre-diabetic

This is P(X = 1) when n = 4. So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 1) = C_{4,1}.(0.1)^{1}.(0.9)^{3} = 0.2916[/tex]

0.2916 = 29.16% probability that one of them is pre-diabetic

Answer:

a.70.95

b. 7.5

Step-by-step explanation

If you divide 2.40 by 32, you get the ratio of the tip to cost, which is 0.075, or 7.5 percent. Multiply 66 by 1.075, which includes both the cost and the tax.

Answer:

The position of Q1 is the 2th number. Q1 is 3.

The position of Q2 is the 4th number. Q1 is 12.

The position of Q3 is the 6th number. Q1 is 14.

IQR is 11.

The first quartile, second quartile and the interquartile range are used to measure the variation of data. Median is a measure of central tendency. Median is the number at the center of the dataset.

Q1 = 1/4 x (n + 1)

1/4 x 8 = 2nd number = 3

Q2 = 1/2 x (n + 1)

1/2 x 8 = 4th number = 12

Q3 = 3/4 x (n + 1)

3/4 x 8 = 6th number = 14

IQR = Q3 - Q1

14 - 3 = 11

Answer:

Step-by-step explanation:

It's not A since that means 1 3/4 or 7/4. That isn't a possible answer since 7/4 is greater than 1.

B: not the answer. You'll make 72000 almost 1000 times bigger if you use B.

C: same reason as B. Anything over 1 will make 72033 larger, not smaller

E: 12/8 > 1. It can't work.

The answer is d . Try it on your calculator. Anything between 0 and 1 make make any number smaller. (include zero, don't include 1).

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the first equation be = A

Now , the value of A is

x - 4y = 1   be equation (1)

Let the first equation be = B

Now , the value of B is

3x + 2y = -11   be equation (2)

Now , on simplifying both equations , we get

Multiply equation (1) by 3 , we get

3x - 12y = 3   be equation (3)

Subtracting equation (2) from equation (3) , we get

-12y - 2y = 3 - ( -11 )

-14y = 14

Divide by -14 on both sides of the equation , we get

y = -1

So , the value of y = -1

Substitute the value of y in equation (1) , we get

x - 4y = 1

x - 4 ( -1 ) = 1

x + 4 = 1

Subtracting 4 on both sides of the equation , we get

x = -3

So , the value of x = -3

Hence , the value of x is -3 and value of y is -1

Answer:

  22.5 square feet

Step-by-step explanation:

The area covered by one tile is the product of its dimensions:

  A = lw

  A = (3/2 ft)(3/2 ft) = 9/4 ft²

The area covered by 10 tiles is 10 times the area covered by one tile. The area covered is ...

  covered by tiles = 10 × 9/4 ft² = 90/4 ft²

  covered by tiles = 22.5 ft²

22 1/2 square feet is the area covered by tiles.

Answer:

Equal to the difference between median and 75th percentile.

Step-by-step explanation:

xth percentile:

If a measure is said to be in the xth percentile, it means that x% of the measures are smaller than it, and (100-x)% are larger.

Distance between percentiles:

If the difference between two percentiles is the same, the difference between the measures should also be the same.

Median:

The 50th percentile is called median.

In this question:

75th percentile - 50th percentile = 25

50th percentile - 25th percentile = 25

The differences should be equal.
