Answer:

The correct answer is option C. 3/5= 0.60

Step-by-step explanation:

It is given that,the  Venn diagram shows sports played by 10 students.

event A = The student plays basketball.

event B = The student plays soccer

<u>To find P(A|B))</u>

P(A) = 6

P(B) = 5

P(A ∩ B) = 3

We have P(A|B) = P(A ∩ B)/P(B)

 = 3/5

 = 0.6

Therefore the correct answer is option C. 3/5= 0.60

you are told that the sun pf another two whole numbers is 20 ans thair differnece is 15 is this possible
-Dominant- [34]

This is not possible if both numbers are whole numbers.

The larger number would be

(20+15)/2 = 17.5

The smaller number would be

(20-15)/2=2.5

So they cannot be whole numbers.

Your estimate that the length of a board is 24 feet. The actual length of the board is 22 feet. Find the percent error.
Tresset [83]

Answer:

9.09%

Step-by-step explanation:

You over estimated by 2 feet.  Find out how much 2 feet of 22 is by dividing 2 by 22...

2/22 = 0.090909090909

To convert a decimal to a percent, multiply the decimal by 100%

0.0909090909(100%) = 9.0909090909% or 9.09%

Blood is a buffer solution. When carbon dioxide is absorbed into the bloodstream, it produces carbonic acid and lowers the pH. T
Irina18 [472]

Answer:

x ≅ 20.10 torr

Step-by-step explanation:

Given that the equation which models blood pH in the question is;

pH(x)=6.1+log(800/x)

where;

pH = 7.7

x = partial pressure of carbon dioxide in arterial blood, measured in torr.

we are asked to find (x)

In order to do that, we use the given equation:

pH(x)=6.1+log(800/x)

since pH = 7.7

7.7 = 6.1 + log (800/x)

7.7 - 6.1 =  log (800/x)

1.6 =  log (800/x)

10^{1.6}= \frac{800}{x}

x= \frac{800}{10^{1.6}}

x = 20.09509145

x ≅ 20.10 torr
