In a certain Algebra 2 class of 30 students, 7 of them play basketball and 11 of them
play baseball. There are 5 students who play both sports. What is the probability that
a student chosen randomly from the class plays basketball or baseball?

Answer:

7:04 p.m.

Step-by-step explanation:

Answer:

7:04

Step-by-step explanation

12-8 + 4

5:52 + 0:08 = 6:00

6:00 + 1:00 + 7:00

7:00 + 0.04 = 7:04

Answer: 4.25, 15, and 38.7°

Step-by-step explanation:

Use SOHCAHTOA

Sine is opposite over hypotenuse

Cosine is adjacent over hypotenuse

Tangent is opposite over adjacent

1.) tan(28) = x/8

8*tan(28) = x

x = 4.25

2.) tan(28) = 8/x

8/tan(28) = x

x = 15

3.) tan(x) = 4/5

x = arctan(4/5)

x = 38.7°

Step-by-step explanation:

Answer:

Step-by-step explanation:

1. Find 15% of $33 to find the tip.

Find 1%  of $33 (move the decimal over 2 places to the left.        $0.33

2. Multiply the 1% tip by 15%

       33 * 15 =  $4.95  

3. Add $33 and $4.95

          4.95 + 33.00 = $37.95 total

This question is incomplete, the complete question is;

Refer to the Exhibit Student Grades. A professor at a local university noted that the grades of her students were normally distributed with a mean of 73 and a standard deviation of 11.

The professor has informed the class that 7.93 percent of her students received grades of A. What is the minimum score needed to receive a grade of A

Answer:

the minimum score needed to receive a grade of A is 88.51

Step-by-step explanation:

Given the data in the question;

Let x represent the grades of the students that were normally distributed with mean μ = 73 and standard deviation σ = 11.

so, The professor has informed the class that 7.93 percent of her students received grades of A

the minimum score needed to receive a grade of A will be:

P( X > x ) = 7.93 %

P( X > x ) = 0.0793

1  - P( X ≤ x ) = 0.0793

- P( X ≤ x ) = 0.0793 - 1

- P( X ≤ x ) = - 0.9207

P( X ≤ x ) = 0.9207

⇒ P( X-μ/σ ≤ x-μ/σ ) = 0.9207

so, x-μ/σ = InvNormal( 0.9207 )  

x-μ/σ = 1.41

(x - 73) / 11 = 1.41

(x - 73) = 1.41 × 11

(x - 73)  = 15.51

x = 15.51 + 73

x = 88.51

Therefore, the minimum score needed to receive a grade of A is 88.51

your answer is -7+16i, because 4-11=-7 and 7i+9i is 16i

Answer: 74.150 + 774.150=1,548.3

in Addition as for muliplcation it is 74.150 * 774.150

Answer:

$4918

Step-by-step explanation:

first income must be divided according to tax bracket

2% tax on first 3000 income= 2% of $3000=$60

3% tax on income after first 3000 but upto 5000= 5000-3000= $2000

=3% of 2000= $60

5% tax on income after second 5000 but upto 12000= 17000-5000

=12000 5% of $12000= $600

Lastly, 5.75% income over 17000=

90000-17000= $73000 so, 5.75 % of 73000= $4197.5

tax= $60+60+600+4197.5

= $4917.5

= $4918

The last answer D.

Step-by-step explanation:

There is a short trick that I just used to answer this question, all you have to do is add 12 plus 5 to see how many 1/12ths you would have and then add up all the answer options until you get to 17, and the only one that does is the last one, D.

Hope this helps :)

Answer:

What is the question??????????

x=60° because if 150°=90°+60° so a line is 180° consequently

90°+30°+x=180°

120°+x°= 180°

x°= 180°-120°= 60°

X^2= AB^2 + BC^2

X^2= 8^2 + 10^2

X^2= 64+100

X^2= 164

X= 12.80

Answer:

The sweater cost 30 dollars.

Step-by-step explanation:

Set up a proportion

x/510 = 250/4250        Multiply both sides by 510

x = 250 * 510/4250      multiply 250 * 510

x = 127500 / 4250        Divide by 4250

x = 30

try filling out the table.

4250                250 dollars

425                   25   dollars

425/25               1     dollar

17                        1     dollar

17*3                     3   dollars

51                        3   dollars

51*10                   30 dollars

510                      30 dollars.
