Answer: y = 4\5*x
We can get this through slope intercept form.
Slope intercept form is y=mx +b where m is the slope and b is the y intercept.
We plug in 4.5 for the slope and 0 for the y-intercept.
Answer:
D and F
Step-by-step explanation:
r: m=-2 y=1 y = -2x + 1
s: m=2 y=1 y = 2x + 1
t: m=1/2 y=1 y = 1/2x + 1
slope of r x slope of t = -2 x 1/2 = -1 (r and t is perpendicular)
all 3line have the same y intercept (0,1), they are not possible to be parallel
Answer:
0.2601
Step-by-step explanation:
There are 19C16 = 969 ways for Lester to choose 16 of the 19 objects.
There are 12C11 = 12 ways to choose 11 vases, and 7C5 = 21 ways to choose a non-vase, for a total of (12)(21) = 252 ways to choose exactly 11 vases in 16 objects.
So, the probability of interest is ...
252/969 ≈ 0.2601
_____
nCk = n!/(k!(n-k)!) ... the number of ways to choose k objects from n
She would weigh 105 pounds on Venus.
120 divided into 8 groups will equal 15.
Then subtract 15 from 120 to get 105 pounds.
Now there are 7 groups of 15 when she is on Venus and 8 groups when she is on Earth. That is where the ratio is used.
