Answer:
Step-by-step explanation:
well you start at origin 0 because there is no y-intercept so you would do rise over run up 1 over 4, 1/4 is your slope
The mean is the average of a set of numbers. So to do that:
add all the numbers 120+235+98+142=$595
Then divide that by the total number in the set, in this case it is 4.
$595/4= $148.75 assuming that the prices given are the final price of the job.
Answer and Step-by-step explanation:
Considering the table attached.
(a) over 9.5 kg;
μ = 8
σ = 0.9
z = 9.5 - 8/0.9 ≈ 1.67
P (Z > 1.67) = 0.5 - P(0<Z<1.67) = 0.5 - 0.4525 = 0.0475
(b) at most 8.6 kg;
z = 8.6-8/0.9 ≈ 0.67
P(Z < 0.67) = 0.5 + P(0<Z<0.67) = 0.5 + 0.2486 = 0.7486
(c) between 7.3 and 9.1 kg.
z₁ = 7.3-8/0.9 ≈ -0.78
z₂ = 9.1 - 8/0.9 ≈ 1.22
P(-0.78 < Z < 1.22) = P(0 < Z < 0.78) + P(0 < Z < 1.22) = 0.2823 + 0.3888 = 0.6711
Answer:
how many 1/3 cups are rings are there in 12 4/6 cups of juice?
12 of 4/6 cup of juice= 12 x 4/6= 8
1/3 cups of rings is there in 8 cups of juice, then we have
1/3 x 8= 8/3
