Answer:
72 is the least common multiple
Answer: 669
Step-by-step explanation:
Given, In a Gallup poll of randomly selected adults, 66% said that they worry about identity theft.
i.e. The proportion of adults said that they worry about identity theft. (p) = 0.66
Sample size : n= 1013
Then , Mean for the sampling distribution of sample proportion = <em>np</em>
= (1013) × (0.66)
= 668.58 ≈ 669 [Round to the nearest whole number]
Hence, the mean of those who do not worry about identify theft is closest to 669 .
Answer:
Both of the angles will add up to 180 degrees so let’s make an equation.
5x-5+2x+10=180
First we collect like terms
5x+2x-5+10=180
Add them up
7x+5=180
Move the constant to the right
7x=180-5
7x=175
7x/7=175/7
x=25
So yes it’s true x=25.
Now we find the respective angles,
5x-5
5(25)-5
125-5
120
So angle one is 120 degrees.
2x+10
2(25)+10
50+10
60
So angle two is 60 degrees.
Now to check,
120+60=180
Step-by-step explanation:
Answer:
The third choice: -4, 0, and 1
Step-by-step explanation:
Finding zeroes is another way of saying solve...set the equation equal to zero and solve..
0 = 2x³ + 6x² - 8x
0 = 2x(x² + 3x - 4) (factor out a 2x from all three terms)
0 = 2x(x + 4)(x - 1) (factor x² + 3x - 4)
So
2x = 0 then x = 0
x + 4 = 0 then x = -4
x - 1 = 0 then x = 1
Our zeroes are -4, 0, and 1
