Answer:
e. 0.0072
Step-by-step explanation:
We are given that a bottling company uses a filling machine to fill plastic bottles with cola. And the contents vary according to a Normal distribution with Mean, μ = 298 ml and Standard deviation, σ = 3 ml .
Let Z =
~ N(0,1) where, Xbar = mean contents of six randomly
selected bottles
n = sample size i.e. 6
So, Probability that the mean contents of six randomly selected bottles is less than 295 ml is given by, P(Xbar < 295)
P(Xbar < 295) = P(
<
) = P(Z < -2.45) = P(Z > 2.45)
Now, using z% score table we find that P(Z > 2.45) = 0.00715 ≈ 0.0072 .
Therefore, option e is correct .
688
x 29
6192
1376 x
19952
So you start by taking 9 from 29 and multiplying it by 688. when you get the answer put it below the line. then multiply the 2 from the 29 and whne you get the answer put a zero on the end and then add the answer you got from 9x688 (6192) and 2x688 (13760) and then thats youre answer. hope it helps!
6 mph.
To find this, create a ratio.
2/20 = x/60
This will allow you to compare here time of twenty minutes to an hour in the same context.
Multiply 2 by 60 and divide by 20 to get the answer of 6 mph.
Thus, Sabrina's average speed in miles per hour is six miles per hour.
Hope this helps!
Hi there!
To solve this problem, you need to use the distributive property. You distribute the 4 inside the parenthesis as well as the 5.
Hope this helps!
Answer:
2/5 yards of fabric
Step-by-step explanation:
A total of 2 yards of fabric is used to make 5 identical pillows. How much fabric is used for each pillow?
5 identical pillows = 2 yards of fabric
1 pillow = x yards
Cross Multiply
x yards × 5 pillows = 2 yards × 1 pillow
x yards = 2 yards × 1 pillow/5 pillows
x yards = 2/5 yards of fabric
Therefore, 2/5 yards of fabric was used for 1 pillow
