Answer:
x=3
Step-by-step explanation:
Hello,
The first thing you do is set up your equation, and we are solving for x so we are going to get x by itself on one side of the = sign.
2x/3+1=3 First thing: subtract 1 from BOTH sides.
-1 -1
----------------------
2x/3=2 Multipliy by 3 on both sides
*3 *3
-----------------------
2x=6 Divide by 2 on both sides
/2 /2
-----------------------
x=3
I hope this helped you!!!
Answer: the probability that the class length is between 50.8 and 51 min is 0.1 ≈ 10%
Step-by-step explanation:
Given data;
lengths of a professor's classes has a continuous uniform distribution between 50.0 min and 52.0 min
hence, height = 1 / ( 52.0 - 50.0) = 1 / 2
now the probability that the class length is between 50.8 and 51 min = ?
P( 50.8 < X < 51 ) = base × height
= ( 51 - 50.8) × 1/2
= 0.2 × 0.5
= 0.1 ≈ 10%
therefore the probability that the class length is between 50.8 and 51 min is 0.1 ≈ 10%
Answer:
D
Step-by-step explanation:
We know it has 2 distinct zeros. This means the discriminant of the quadratic is positive and must have 2 real zeros that can be rational or irrational. We also know the quadratic has rational coefficients which means both are either rational or irrational. They can not be one of either. Since it tells us one is rational, the other must be too.
Answer: maybe 20

Answer:
y= 450x
Step-by-step explanation:
Given data
Let y represent the total amount of money
Let x represent the number of home runs
For each run they donate $450
We can model this situation as
y= 450x
