Answer:

80 - 2x

Step-by-step explanation:

Given

Total number of people = 80 people

Total men = x men

Total women = x women

Let the number of childeren be c

x + x + c = 80

Make c the subject of the formula

c = 80 - (x+x)

c = 80 - 2x

Hence the total children attending is 80 - 2x

Answer:

(18,0)

Step-by-step explanation:

Set y equal to zero

0=2/3x-12

12=2/3x

x=18, the x intercept is (18,0)

Answer:

x-intercept at (18, 0)

Step-by-step explanation:

to find x-intercept, set 'y' equal to zero and solve for 'x'

0 = 2/3x - 12

12 = 2/3x

2x = 36

x = 18

Answer:

Answer:

[tex]a.\ \frac{5}{36}\\b.\ \frac{1}{12}\\c.\ \frac{2}{9}\\d.\ $Not mutually exclusive$[/tex]

Step-by-step explanation:

Given two fair dice are rolled, one green and one red.

To find:

a. Probability of getting a sum of 8.

b. Probability of getting a sum of 4.

c. Probability of getting a sum of 8 or 4.

d. Are these outcomes mutually exclusive?

Solution:

First of all, let us have a look at the output of roll of two dice.

There are a total of 36 outcomes.

{(1,1) (1,2) (1,3) (1,4) (1,5) (1,6)

(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)

(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)

(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)

(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)

(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)}

a. Getting a sum equal to 8, we have following outcomes:

{(2, 6), (3,5), (4, 4), (5,3), (6, 2)}

5 possible outcomes for this event.

Formula for probability of an event E can be observed as:

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]

[tex]P($Getting 8$) = \dfrac{5}{36}[/tex]

b. Getting a sum equal to 4, we have following outcomes:

{(1, 3), (2,2), (3, 1)}

3 possible outcomes for this event.

Formula for probability of an event E can be observed as:

[tex]P($Getting 4$) = \dfrac{3}{36} = \dfrac{1}{12}[/tex]

c. Probability of getting a sum of 8 or 4?

Following possible outcomes are there:

{(2, 6), (3,5), (4, 4), (5,3), (6, 2), (1, 3), (2,2), (3, 1)}

Total 8 possible outcomes:

[tex]P($Getting 8 or 4$) = \dfrac{8}{36} = \dfrac{2}{9}[/tex]

d. Are these outcomes mutually exclusive?

These events are not mutually exclusive because they contain the similar outcome from both of the dice.

i.e. (4, 4) and (2, 2)

Answer:

The value of x is -3.

Step-by-step explanation:

It is given that:

y=3x+5       Eqn 1

y=4x+8       Eqn 2

Putting value of y from Eqn 2 in Eqn 1

4x + 8 = 3x + 5

4x - 3x = 5 - 8

x = -3

Therefore,

The value of x is -3.

Answer:

$17 on food per person

Step-by-step explanation:

The cost of parking a car is $5

Assuming that the friends used one car, then the parking cost=$5

Admission cost is 19

For three people, Admission cost =19*3=57

TOTAl COSTS=Parking cost+Admission cost

TOTAl COSTS=57+5=62

Remaining amount can be used for food

FOOD= 113-62=51

Therefore each person can spend 51/3=$17 on food

I hope this was helpful and clear to follow

Answer:

$8

Step-by-step explanation:

19 x 4 + 5 + c =113

81 + c =113

-81         -81

c =32

32 divided by 4 ppl = 8

Answer:  150%

Step-by-step explanation:

6/4 is the same as 3/2 or 1¹/₂

Change to a decimal by dividing the denominator into the numerator

3/2 = 1.5

Then multiply by 100 to change from a decimal to a percent.

1.5 × 100 = 150  Add the % sign

150%

Answer

[tex]P(A) = 0.30[/tex]

[tex]P(B) = 0.77[/tex]

[tex]P(A\ n\ B) = 0.22[/tex]

[tex]P(A\ u\ B) = 0.85[/tex]

Explanation:

Given

See attachment for proper data presentation

[tex]n = 100[/tex] --- Sample

A = Supplier 1

B = Conforms to specification

Solving (a): P(A)

Here, we only consider data in sample 1 row.

Here:

[tex]Yes = 22[/tex] and [tex]No = 8[/tex]

[tex]n(A) = Yes + No[/tex]

[tex]n(A) = 22 + 8[/tex]

[tex]n(A) = 30[/tex]

P(A) is then calculated as:

[tex]P(A) = \frac{n(A)}{Sample}[/tex]

[tex]P(A) = \frac{30}{100}[/tex]

[tex]P(A) = 0.30[/tex]

Solving (b): P(B)

We only consider data in the Yes column.

Here:

[tex](1) = 22[/tex]    [tex](2) = 25[/tex] and [tex](3) = 30[/tex]

[tex]n(B) = (1) + (2) + (3)[/tex]

[tex]n(B) = 22 + 25 + 30[/tex]

[tex]n(B) = 77[/tex]

P(B) is then calculated as:

[tex]P(B) = \frac{n(B)}{Sample}[/tex]

[tex]P(B) = \frac{77}{100}[/tex]

[tex]P(B) = 0.77[/tex]

Solving (c): P(A n B)

Here, we only consider the similar cell in the yes column and sample 1 row.

i.e. [Supplier 1][Yes]

This is represented as: n(A n B)

[tex]n(A\ n\ B) = 22[/tex]

The probability is then calculated as:

[tex]P(A\ n\ B) = \frac{n(A\ n\ B)}{Sample}[/tex]

[tex]P(A\ n\ B) = \frac{22}{100}[/tex]

[tex]P(A\ n\ B) = 0.22[/tex]

Solving (d): P(A u B)

This is calculated as:

[tex]P(A\ u\ B) = P(A) + P(B) - P(A\ n\ B)[/tex]

This gives:

[tex]P(A\ u\ B) = \frac{30}{100} + \frac{77}{100} - \frac{22}{100}[/tex]

Take LCM

[tex]P(A\ u\ B) = \frac{30+77-22}{100}[/tex]

[tex]P(A\ u\ B) = \frac{85}{100}[/tex]

[tex]P(A\ u\ B) = 0.85[/tex]
