Answer:
Q=30
Step-by-step explanation:
4x+x+x=180 || 6x=180 || x=30
Answer:
y-4 =-1(x+1) point slope form
y-2 = -1(x-1)
y = -x +3 slope intercept form
Step-by-step explanation:
We have 2 points, we can find the slope
m = (y2-y1)/(x2-x1)
= (2-4)/(1--1)
(2-4)/(1+1)
-2/2
=-1
The slope is -1
Then we can use point slope form to find an equation
y-y1 =m(x-x1)
y-4 = -1(x--1)
y-4 =-1(x+1) point slope form
Using the other point
y-2 = -1(x-1)
Distribute the -1
y-2 = -1x +1
Add 2 to each side
y-2+2 = -x+1+2
y = -x +3 slope intercept form
Answer:
a. 5.33 × 10⁻⁴ b. 4.568 × 10⁻³
Step-by-step explanation:
a. This situation represents a binomial probability. Let p = probability that tire is defective = 1% = 0.01, then q = probability that tire is not defective = 1 - p = 1 - 0.01 = 0.99 = 99%.
Since there are 750 tires, the probablility that no tire is defective is P = ⁷⁵⁰C₀q⁷⁵⁰p⁰
= (1) (0.99)⁷⁵⁰(0.01)⁰
= 5.33 × 10⁻⁴
b. The probability that less than two tires will be defective P'
So, P' = ⁷⁵⁰C₀q⁷⁵⁰p⁰ + ⁷⁵⁰C₁q⁷⁴⁹p¹
= (1) (0.99)⁷⁵⁰(0.01)⁰ + (750)(0.99)⁷⁴⁹(0.01)¹
= 5.33 × 10⁻⁴ + 0.004035
= 45.68 × 10⁻⁴
= 4.568 × 10⁻³
Answer:
?=49
Step-by-step explanation:
You have to divide the middle term by 2 and then square it.
14/2=7
7^2=49
Therefore, ?=49
I hope this helped and have a good rest of your day!
The answer is 1/2 because the 1 and 3 = 4 and -5 + -3 = -8 and that is 4/8 which = 1/2
