The question is an illustration of probability, and the value of P(B|C) is P(B|C) = 9/24 =0.38

How to determine the probability P(B|C)?

The table is given as:

C D Total

A 15 21 36

B 9 25 34

Total 24 46 70

The probability (BIC) is calculated using:

P(B|C) = n(B and C)/n(C)

From the table, we have:

n(B and C) = 9

n(C) = 24

So, the equation becomes

P(B|C) = 9/24

Evaluate

P(B|C) = 0.38

Hence, the value of P(B|C) is P(B|C) = 9/24 =0.38

DISTANCE

The formula in finding the distance between two points is given below:

[tex] \boxed{\bold{\:\:d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \:\:}}[/tex]

Now, you know the distance formula. So, let us try solving the given problem using the distance formula.

Problem: What is the distance between (-2, 0) and (-11, 0)?

From inspection on the given problem:

[tex]\sf (x_1, y_1) = (-2, 0)[/tex][tex]\sf (x_2, y_2) = (-11, 0)[/tex]

Substitute the given values into the distance formula and solve for d:

[tex]\sf d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

[tex]\sf d = \sqrt{[-11 - (-2)]^2 + (0 - 0)^2}[/tex]

[tex]\sf d = \sqrt{(9)^2 + (0)^2}[/tex]

[tex]\sf d = \sqrt{81 + 0}[/tex]

[tex]\sf d = \sqrt{81}[/tex]

[tex]\bold{d = 9 \: units}[/tex]

Therefore, the distance between two points is 9 units.

Which graph represents the solution of y > x2 + 2?

Answers

The graph that represents the solution of y>x²+2 is given below.

The given inequality is y>x²+2.

We need to identify which graph represents the solution of y>x²+2.

What is an inequality graph?

Inequalities that use ≤ or ≥ symbols are plotted with a solid line to show that the line is included in the region.

For example, this graph shows inequality. This can be seen as there is a dashed line, and the region where the coordinates are less than -1 is shaded.

Graph the inequality by finding the boundary line, and then shading the appropriate area.

Put x=0, 1, 2, 3,....in the inequality and solve for y.

We get y=2, 3, 6, 11,...

Suppose A< - 1 what must be true about the value of b so that ab< a

Answers

Answer:

b must be positive

Step-by-step explanation:

if a is less than -1

that means to get smaller numbers

b needs to be positive

so that when a is multiplied by b you would have

numbers that are more negative

Answer:

b > 1

Step-by-step explanation:

Given:

a < -1 ab < a

Substituting a = -1 into ab < a

⇒ (-1)b < -1

⇒ -b < -1

⇒ b > 1

If a < -1 then a is negative. If ab < a then ab is also negative.

In order for ab to be negative (when a is negative) b must be positive.

For ab < a then b > 1.

Proof

If b = 0.5 and a = -1.5 then ab = -0.75

As -0.75 > -1.5 then ab > a so this cannot be true.

If b = 1.5 and a = -1.5 then ab = -2.25

As -2.25 < -1.5 then ab < a so this is true.

Therefore b > 1

Answers

Answer:

The answer is C (0.30) are NOT going to particulate

Step-by-step explanation:

We can find the answer by simply putting all of the results into order, which gives the following for the non-participants:

28: 6's

27: 7's

29: 8's

15: 9's

Now to find the answer, we must know the total amount of results, which I found to be 250. We also need to know the total amount of non-participants there are, which is 99. So if we take 99 and divide it by 250 (99/250); we get 0.396. Although this isn't the exact answer, it is the closest.

To further prove that this should be right, Yuri found 60% of students to participate, which leaves around 40% left to not participate. So this should be right.

Sharon has a soap and water mixture that is 36% soap. How many liters of water must

Sharon add to 5 liters of this mixture to make a solution that is 12% soap?

Answers

The volume of water that Sharon must add to the 5 liters mixture to make a solution that is 12% soap is 10 liters

Dilution law

From the question, we are to determine how many liters of water must Sharon add to 12% soap solution

Using the dilution law formula,

C₁V₁ = C₂V₂

Where C₁ is the initial concentration

V₁ is the initial volume

C₂ is the final concentration

and V₂ is the final volume

From the given information,

C₁ = 36%

V₁ = 5 liters

C₂ = 12%

V₂ = ?

Putting the parameters into the equation, we get

36 × 5 = 12 × V₂

180 = 12V₂

∴ V₂ = 180 / 12

V₂ = 15 liters

This means the final volume of the solution will be 15 liters.

Volume of water that must be added = V₂ - V₁

Volume of water that must be added = 15 liter - 5 liters

Volume of water that must be added = 10 liters

Hence, the volume of water that Sharon must add to the 5 liters mixture to make a solution that is 12% soap is 10 liters.

Step-by-step explanation:

Since this P-value is less than the usual significance level of 0.05, we would reject the null hypothesis and conclude that there is evidence of a difference between the true population mean and 36 at the 0.05 level of significance.

What is hypothesis testing?

Hypothesis testing is a statistical method that is used to make decisions about a population based on a sample of data.

It involves testing a null hypothesis (H0) against an alternative hypothesis (Ha) using statistical techniques.

To find the P-value for Jasper's test, we need to use the t-distribution with degrees of freedom (df) equal to the sample size minus one,

Using a t-table or a calculator, we can find that the two-tailed P-value for t=2.4 with df=15 is approximately 0.029.

This means that if the null hypothesis is true (i.e., if the true population mean is 36), the probability of observing a sample mean as extreme as or more extreme than the one obtained by Jasper is 0.029.
