Answer 2

A) 6/25

B) 13/15

C) 4/15

Explanation:

A) P(both will be alive) = (3/5)(2/5) = 6/25

B) P(at least one will be alive) = 1-P(both die) = 1-(2/5)(1/3) = 13/15

C) P(only the wife will be alive)=(2/5)(2/3) = 4/15

Answer:

Pregnant women have the option of being scanned for Cystic Fibrosis risks in their unborn babies. If a mother or a father have a certain recessive gene, the baby is at risk for Cystic Fibrosis.

Given the three events, which of the following statements is true?  

Select all that apply.

Event A: The mother or father carries the recessive gene.

Event B: The father carries the recessive gene.

Event C: The baby is at risk for Cystic Fibrosis.

Select all that apply:

Event A and Event B are mutually exclusive.

Event B and Event C are mutually exclusive.

Event A and Event C are not mutually exclusive.

Event A and Event C are mutually exclusive.

Event A and Event C are not mutually exclusive.

Remember that in general, A and B are mutually exclusive events if they cannot occur at the same time. This means that A and B do not share any outcomes and P(A AND B)=0.

In this question, note that if the mother or father carries the recessive gene for cystic fibrosis, the baby is at risk. So here, A and C are not mutually exclusive, and B and C are not mutually exclusive.

A and B are not mutually exclusive because they share an outcome: the father carrying the recessive gene.

Zack bought 2 1/2 pounds of green grapes and 1/5 of a pound of red grapes. How much
more did the green grapes weigh than the red grapes?

Answers

Answer:23/10 pounds heavier

Step-by-step explanation:

first we transform the mixed fraction to a normal fraction

2 1/2 = 5/2

Now transform

5/2 = 25/10

1/5 = 2/10

25/10 - 2/10 = 23/10

So the green grapes weigh 23/10 pounds more than the red grapes.

let f be the function given by f(x)=sin x + e^-x +3x. which of the following statements is true for y=f(x).

Answers

Applying derivatives, it is found that the correct options are:

A. [tex]y^{\prime\prime}(x) = -\sin{x} + e^{-x}[/tex]

D. [tex]y - y^{\prime\prime\prime\prime}(x) = 3x[/tex]

The function given is:

[tex]f(x) = \sin{x} + e^{-x} + 3x[/tex]

It's first four derivatives are:

[tex]y^{\prime}(x) = \cos{x} - e^{-x} + 3[/tex]

[tex]y^{\prime\prime}(x) = -\sin{x} + e^{-x}[/tex]

Hence, option A is correct.

[tex]y^{\prime\prime\prime}(x) = -cos{x} - e^{-x}[/tex]

[tex]y^{\prime\prime\prime}(x) \neq y^{\prime}(x)[/tex], hence, option B is incorrect.

[tex]y^{\prime\prime\prime\prime}(x) = sin{x} + e^{-x}[/tex]

It is not the multiplication of the first and of the third derivative, hence option C is incorrect.

[tex]y - y^{\prime\prime\prime\prime}(x) = 3x[/tex]

[tex]\sin{x} + e^{-x} + 3x - \sin{x} - e^{-x} = 3x[/tex]

[tex]3x = 3x[/tex]

Hence, option D is correct.

a company blends 1000 bushels of two types of apples to make a beverage that contains 12% real-juice content. One of the two types of apple contains 10% real-juice content and the other contains 15% real juice content. how many bushels of each type of apple are needed?

Answers

Answer:

400 bushels of the 15%

600 bushels of the 10%

Step-by-step explanation:

x bushels of the 15%  plus the balance of 1000 bushels at 10% yield 1000 bushels at 12%

15x + 10(1000 - x) = 12(1000)

distribute

15x + 10000 - 10x = 12000

Combine like terms

5x = 2000

Divide both sides by 5

x = 400 bushels of the 15%

1000 - x = 600 bushels of the 10%

The number of bushels of the 15% is 400, and the number of bushels of the 10% is 600.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have:

A company blends 1000 bushels of two types of apples to make a beverage that contains 12% real-juice content.

Let x be the bushels.

One of the two types of an apple contains 10% real-juice content and the other contains 15% real juice content.

The linear equation can be framed:

15x + 10(1000 - x) = 12(1000)

By using the distributive property:

15x + 10000 - 10x = 12000

5x = 2000  (combine like terms)

x = 400 bushels of the 15%

= 1000 - x

= 1000 - 400

= 600 bushels of the 10%

Thus, the number of bushels of the 15% is 400, and the number of bushels of the 10% is 600.

If a university accepts 40% of those students who apply for entrance, and 75% of admitted applicants accept, what percentage of total applicants actually accepts offers of admission?​

Answers

Answer:

30%

Step-by-step explanation:

75% of 40 is 30

The percentage of total applicants that accepts offers of admission is = 30%

Calculation of percentage of total applicants

The percentage of acceptance for students that apply for entrance is = 40%

The percentage of admitted applicants that accept the offer= 75%

This means that it is only 75% of 40% of the accepted students actually accept the offer of admission.

That is, 75/100 × 40%

= 3000/100

= 30%

Therefore, the percentage of total applicants that accepts offers of admission is = 30%
