Identify the domain and range of each relation. Is the relation a function? Explain.
Answer:
Domain = city
Range = team
this is not a function, because each input should only have one output. There should not be 2 arrows coming out of a domain or known as the x.
How many 3-letter "words" can be formed from the standard 26-letter alphabet, if the first letter must be a vowel (A, E, I, O, or U)? (We aren't necessarily talking about English words; something like EQX is perfectly valid here.)
Answer:
3380
Step-by-step explanation:
There are five choices for the first letter, and 26 choices each for the middle and last letters.
So,
5*26*26=3380

X+1 , 2x+3 and X+7 are the second, third and fourth terms of an arithmetic series. Find the value of X and hence calculate the common difference.
Answer:
x = 1,
Common Difference = -3
Step-by-step explanation:
Each number in series has the same difference, hence
(x + 1) - (2x+3) = (2x + 3) - (x + 7) Solve to find => x = 1Plug in value of x into (x+1) - (2x+3)Which solves for -3
Answer:
x=1
c.d.=3
Step-by-step explanation:
2(2x+3)=x+1+x+7
4x+6=2x+8
4x-2x=8-6
2x=2
x=1
so terms are 2,5,8

In a group of 100 students, 40 like Computer Science (group A), 30 like Philosophy
(group B), and 20 like both (group A∩B). If a student chosen randomly likes Computer
Science, what is the probability that they also like Philosophy?
Given:
Total number of student = 40
Students who like Computer Science (group A) = 40
Students who like Philosophy (group B) = 30
Students who like both (group A∩B) = 20
To find:
If a student chosen randomly likes Computer Science, what is the probability that they also like Philosophy?
Solution:
Let the following events,
A: Student like Computer Science
B: Student like Philosophy
Now,
[tex]P(A)=\dfrac{40}{100}=0.4[/tex]
[tex]P(B)=\dfrac{30}{100}=0.3[/tex]
[tex]P(A\cap B)=\dfrac{20}{100}=0.2[/tex]
We need to find the probability that the student like Philosophy if it is given that he likes Computer science, i.e, [tex]P(\dfrac{B}{A})[/tex].
Using conditional probability, we get
[tex]P(\dfrac{B}{A})=\dfrac{P(A\cap B)}{P(A)}[/tex]
[tex]P(\dfrac{B}{A})=\dfrac{0.2}{0.4}[/tex]
[tex]P(\dfrac{B}{A})=\dfrac{1}{2}[/tex]
[tex]P(\dfrac{B}{A})=0.5[/tex]
Therefore, the required probability is 0.5.
Four more than three times a number is greater than twenty-two.
and please solve.
Answer:
3x + 4>22 or x>6
Step-by-step explanation:
four more = +4
three times a number = 3(x)
greater than twenty two = >22
so
3x + 4 > 22
that's the equation now if it were to be solved
3x + 4 > 22
-4 -4
3x > 18
/3 /3
x > 6

adam is going to a carnival that has games and rides. each game costs $1.50 and each ride costs $3. Adam spent $15 altogether. number of games played was 3 times the number of rides. grapically solve
The number of games played is 6 and the number of rides is 2.
Here it is given that the number of games played was 3 times the number of rides. So, by this, we get the value of both is the ratio.
That is,
number of games played: number of rides = 3: 1
Let x be the common ratio. So, we have
Number of games played = 3x, and number of rides = x
It is given that the cost of each game is $1.50 and cost of each ride is $3 and the total cost is $15.
By this, we get an equation,
1.50 × 3x + 3 × x = 15
4.5x + 3x = 15
7.5x = 15
x = 2
Therefore the number of games= 3x = 3×2 = 6
The number of rides = x = 2

Marla bought twice as many pounds of cherries as grapes. She paid $15.00 for a total of 4.5 pounds of both items. Cherries cost twice as much as grapes. How much do grapes cost per pound?
For the grapes he paid 5.695 and the cherries 10.005. The cherries cost him $4.64 extra, which is the correct answer.
3 x 1.45 = 4.35
1.45 x .2 = .29
4.35 +.29 = 4.64
What are cherries ?A cherry is a fruit that is a fleshy drupe that is produced by numerous plants in the genus Prunus. Prunus avium and Prunus cerasus, two species with sweet and tart varieties, respectively, are cultivars from which commercial cherries are produced.
Cherries have a low calorie count and are packed with fiber, vitamins, minerals, nutrients, and other healthy elements. A, C, and K vitamins are provided. Potassium, magnesium, and calcium are also present in each fruit with a long stem. Beta-carotene, an antioxidant, and choline, a necessary nutrient, are also brought by them.

The number of a certain bacteria in a sample of refrigerated food product is given by, n(c)=10c2-20c+600, where c is degrees Celsius. Evaluate n(5) and describe the meaning of your answer.
The number of bacteria in a sample of refrigerated food product at 5 degrees Celsius is 750
How to determine the valueGiven the function;
n(c)=10c² - 20c + 600
Where:
n represents the number of certain bacteria in a sample of refrigerated food product c is the degrees CelsiusTo determine n(5), we substitute the value of c as 5 degrees
We have;
n(5) = 10(5)² - 20(5) + 600
Find the square
n(5) = 10(25) - 100 + 600
n(5) = 250 - 100 + 600
n(5) = 750
Thus, the number of bacteria in a sample of refrigerated food product at 5 degrees Celsius is 750
