Answer:
1.4
Step-by-step explanation:
Probability of selecting a red counter :
Number of red counter / total number of counters
5 / (5 + 3) = 5 /8 = 0.625
Probability of selecting a blue counter = 0.375
Let number of red counters :
0, 1 or 2
0 red counters :
Expected value = x * p(x)
0 + (0.625*1) + (0.390625 * 2)
0 + 0.625 + 0.78125 = 1.40625
Expected number of red counters = 1.4
The answer is 9
12 ounces x
--------------- = ----------------
10 pounds of soil 120 pounds of soil
Set the equation up as a proportion and solve for x:
10x = 1440
---- -----
10 10
x = 144 ounces
The question asks for the answer in pounds, and 16 ounces = 1 pound.
144/16 = 9
I think 3 because if u divide 207 by 69 you get 3
Answer: y=-3/4x-2
Step-by-step explanation:
Write an equation of a line in slope-intercept from with the given slope, slope:–3/4, y-intercept: –2
The y-intercept is at (0,-2)
Then we write the equation using y=mx+b becuase that is the point slope form.
m=-3/4 which was given in the question
because y-intercept is at (0,-2)
y=-2
x=0
-2=-3/4(0)+b
-2=0+b
-2=b
now we know that m is -3/4 and b is -2
Hence the equation is y=-3/4x-2
It would be 20*7 which will give you 140 miles in 7 hours
