Answer:

A 5% possibility.

Step-by-step explanation:

Find all of the totals:

total male = 4+6+2+2=14

total female = 3+4+6+3=16

freshman = 4+3=7

sophomore = 6+4=10

Junior = 2+6=8

Senior = 2+3 = 5

total overall= 5+8+10+7+16+14=60

Female seniors are = 3

So 3/60 = 0.05=5%

[1] 0.25, 0.25%, or \frac{1}{4}

     We will divide the number of wanted outcomes by possible outcomes.

\displaystyle \frac{\text{wanted outcomes}}{\text{possible outcomes}} =\frac{5}{3+5+12} =\frac{5}{20} =\frac{1}{4}

[2]

     We will follow the same steps as problem 1.

MTHMTCS = 7 consonants

AEAI = 4  vowels

MTHEMTICS = 9 letters that are not A's

MATHEMATICS = total of 11 letters

(a)

\displaystyle \frac{\text{wanted outcomes}}{\text{possible outcomes}} =\frac{7}{11}

(b)

\displaystyle \frac{\text{wanted outcomes}}{\text{possible outcomes}} =\frac{4}{11}

(c)

\displaystyle \frac{\text{wanted outcomes}}{\text{possible outcomes}} =\frac{9}{11}

[3] 0.877

     If the probability that a television is defective is 0.123, then the probability that a television is not defective is:

1 - 0.123 = 0.877

Find the equation of the line that passes through the points (3,-2) and (6,-8)
Karolina [17]

Answer:

2x + y = 4

Step-by-step explanation:

The two-point form of the equation of a line is:

y - y_1 = \dfrac{y_2 - y_1}{x_2 - x_1}(x - x_1)

We have:

x1 = 3

y1 = -2

x2 = 6

y2 = -8

Plug in all the values where they belong in the equation above.

y - (-2) = \dfrac{-8 - (-2)}{6 - 3}(x - 3)

Simplify.

y + 2 = \dfrac{-6}{3}(x - 3)

y + 2 = -2(x - 3)

y + 2 = -2x + 6

2x + y = 4

PLEASE HELP!!!!!!!!!!
agasfer [191]

Answer:

a = 30

b = 15

c = 3

d = 30

e = 10

f = 20

Step-by-step explanation:

60 deg and a + 30 are alt int <S and congruent

a + 30 = 60

a = 30

a + 30 and a + 2b are corresponding angles and congruent

a + 2b = a + 30

2b = 30

b = 15

a + 2b and 5b - 5c are vertical angles and congruent

5b - 5c = a + 2b

5(15) - 5c = 30 + 2(15)

75 - 5c = 30 + 30

75 - 5c = 60

-5c = -15

c = 3

a + 2b and 10c + d are corresponding angles and congruent

10c + d = a + 2b

10(3) + d = 30 + 2(15)

d + 30 = 60

d = 30

5b - 5c and 2d + 6e are supplementary and add to 180

5b - 5c + 2d + 6e = 180

5(15) - 5(3) + 2(30) + 6e = 180

75 - 15 + 60 + 6e = 180

6e + 120 = 180

6e = 60

e = 10

2d + 6e and 4f + 4e are alt int angles and congruent.

4f + 4e = 2d + 6e

4f + 4(10) + 2(30) + 6(10)

4f + 40 = 60 + 60

4f + 40 = 120

4f = 80

f = 20
