Answer:
3
Step-by-step explanation:
the equation is written in slope intercept for x is the number on the x axis and the + is the slope
Answer:
a) 120
b) 10
c) 1/12
Step-by-step explanation:
The number of ways that a sample of r can be selected from a population of n is:
nCr = n! / (r! (n−r)!)
a) 3 people selected from a group of 10
₁₀C₃ = 120
b) 3 women selected from a group of 5
₅C₃ = 10
c) Of the 120 committees that can be chose, 10 are all women. So the probability is 10/120 = 1/12.
Let’s place x in the blank
7.14 + 33/100 = x/100 + 33/100
x = 714
If you search it up, the distance from Washington DC to Charlotte is 404.9 miles.
The formula for speed is distance divided by time. We can easily do that with this equation:
404.9 / 6.5 = 62.2923077, or about 63 miles per hour.
Answer:
The x intercepts are -2 ,4
Step-by-step explanation:
f(x)=(x-4)(x+2)
We set the function equal to 0 to determine the x intercepts
0 = (x-4)(x+2)
Using the zero product property
0 = x-4 0 = x+2
x=4 x=-2
The x intercepts are -2 ,4
