Answer:
{x:x is a natural number less than 6}
Step-by-step explanation:
Set builder is a type of set where we have to represent any value inside a set
by using the variable x, v, b, a, c etc.
Eg A={1,2,3,4}
For eg {a: a is a natural number less than 5}
Range is the difference between the lowest and highest values.
997- 247= 750
Answer:
Step-by-step explanation:
We need to find the probability that the mechanic will service or more cars.
It's a simpler one given that we have the probabilities of servicing 4 or less cars.
P(at least 5 cars) is given by subtracting the probabilities of servicing both 3 and 4 cars.
Complete Question:
Lenny asked 125 randomly chosen seventh grade students at his school to name their favorite beverage there are 1500 seventh grade students in the school predict the number of seventh grade students in his schoolwhose favorite food is pizza. 58 of the 125 students likes pizza.
Answer:
n = 696
Step-by-step explanation:
Sample size = 125
number of students out of the 125 that like Pizza = 58
Probability that a student will like pizza, P = 58/125
P = 0.464
Since there are 1500 seventh grade students in the school, based on the probability that a student likes pizza = 0.464, number of seventh grade students in the school that like pizza will be:
n = 100 * P
n = 1500 * 0.464
n = 696
Answer:
The inverse is 1/3x -2
Step-by-step explanation:
f (x) = 3x + 6
y = 3x+6
Exchange x and y
x = 3y+6
Subtract 6 from each side
x-6 = 3y+6-6
x-6 = 3y
Divide by 3
1/3x - 6/3 = y
1/3x -2 = y
The inverse is 1/3x -2
