You and three friends are going to the fair. The cost for
parking is $5 per car and admission to the fair is $19 per person. If you have
a total of $113, how much can each person spend on food?
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:
r = 4, s = 3, t = 5Step-by-step explanation:
Solving quadratic equation:
5x² - 8x + 5 = 0x = (-b ± √b²-4ac)/2ax = (8 ± √8²-4*5*5)/2*5x = (8 ± √64-100)/10x = (8 ±√-36)/10x = (8 ± 6i)/10x = (4 ± 3i)/5x = (r ± si)/t
r = 4, s = 3, t = 5
a in the solution to the system of equations below?

Answer:
A=45
15.25
Step-by-step explanation:
Use the following x-values (0, 1, 2, 3) to find ordered pairs for this equation: y = 2x - 3
Step-by-step explanation:
When x = 0, y = 2(0) - 3 = -3.
When x = 1, y = 2(1) - 3 = -1.
When x = 2, y = 2(2) - 3 = 1.
When x = 3, y = 2(3) - 3 = 3.
The ordered pairs are (0, -3), (1, -1), (2, 1), (3, 3).
You roll two fair dice, a green one and a red one.
Required:
a. What is the probability of getting a sum of 8? (Enter your answer as a fraction.)
b. What is the probability of getting a sum of 4?
c. What is the probability of getting a sum of 8 or 4?
d. Are these outcomes mutually exclusive?
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)

What is 23% of 3500
Does any one know it’s for a test lol
Answer:
805
Step-by-step explanation:
It's kinda hard to explain but first you would convert 23% to a decimal. To do that, move the decimal 2 places to the left, resulting in 0.23. Then multiply 3500 by 0.23 to get your answer.
Find the x- and y-intercepts of the graph of the equation.
y = 2/3x-12
Help plz
I know the y is 0,-12 but is the x intercept?
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

80 people attended a meeting. There was x men and x women and the rest were children. How many children attended the meeting
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
-10(1 - 9x) + 6(x - 10)

Samples of emissions from three suppliers are classified for conformance to air-quality specifications. The results from 100 samples are summarized as follows:
conforms
yes no
1 22 8
supplier 2 25 5
3 30 10
Let A denote the event that a sample is from supplier 1, and let B denote the event that a sample from any supplier conforms to specifications. If a disk is selected at random, determine the following probabilities.
a. P(A)=0.3
b. P(B)=0.77
c. P(A ∩ B) =0.22
d. P(A U B)=0.85
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]
