<span>Plug in f(x) = 3 to solve 

</span>f (x) = -4x + 9

3 = -4x + 9 

3-9=-4x 

-6=-4x 

-6/-4=x 

6/4=x 

3/2=x 

x=3/2

John randomly picks a number from 1 to 5 (both inclusive) and a letter from A to E (both inclusive). What is the probability tha
Greeley [361]

Answer:

P(A \cap B) = P(A) *P(B) =\frac{1}{5} \frac{1}{5}= \frac{1}{25}

So then the best option would be:

a. 1/25

Step-by-step explanation:

For this case we assume that the sample space for the numbers is :

S_1= [A,B,C,D,E]

And the sample space for the numbers is:

S_2 =[1,2,3,4,5]

Both sampling spaces with a size of 5.

We define the following events:

A="We select a 2 from the numbers"

B= "We select a E from the letters"

We can find the individual probabilities for each event like this:

P(A)= \frac{1}{5}

P(B) = \frac{1}{5}

And assuming independence we can find the probability required like this:

P(A \cap B) = P(A) *P(B) =\frac{1}{5} \frac{1}{5}= \frac{1}{25}

The last probability is the probability of obtain obtain a 2 AND an E

So then the best option would be:

a. 1/25

What is m∠BAC.<br><br> ............
gizmo_the_mogwai [7]

Answer:

37 degrees

Step-by-step explanation:

1. m∠CBA = 71+45 = 116 degrees

2. m∠CBA = m∠CDA because of the quadrilateral property of opposite sides.

3. m∠CBA + m∠CDA = 2*116 = 232.

4. Total angle measure of a quadrilateral is 360 degrees, so m∠BAD + m∠BCD = 360-232 = 128 degrees.

5. m∠BAD = m∠BCD = 128/2 = 64 degrees

6. m∠BAC = m∠BAD - m∠CAD = 64 - 27 = 37 degrees

HELPPPPPPP PLEASEEEEEE
bearhunter [10]

Answer:

0.95 miles per minute

19 miles in 20 minutes

Step-by-step explanation:

To find out how many miles traveled in a minute, we will divide 57 by 60, because there are 60 minutes in an hour, and there were 57 miles traveled in a hour. This gives you the rate of miles per minute (0.95), and to get the answer for 20 minutes, just multiply 0.95 by 20 (19 miles).
