Answer:
<u>1.13 kg</u>
Step-by-step explanation:
We know that :
<u>Multiply both sides by 1.13</u>
- 1000 x 1.13 = 1 x 1.13
- 1130 grams = <u>1.13 kilograms</u>
they can ship out 271 boxes each day. 3,258/12 is 271.5 but the 0.5 doesn't matter bc that'd be half a box. a total of 2 crates can be filled fully with another crate that isn't completely full (in total 3 crates max)
Answer:
3/20
Step-by-step explanation:
a. Find the probability that an individual distance is
greater than 214.30 cm
We find for the value of z score using the formula:
z = (x – u) / s
z = (214.30 – 205) / 8.3
z = 1.12
Since we are looking for x > 214.30 cm, we use the
right tailed test to find for P at z = 1.12 from the tables:
P = 0.1314
b. Find the probability that the mean for 20 randomly
selected distances is greater than 202.80 cm
We find for the value of z score using the formula:
z = (x – u) / s
z = (202.80 – 205) / 8.3
z = -0.265
Since we are looking for x > 202.80 cm, we use the
right tailed test to find for P at z = -0.265 from the tables:
P = 0.6045
c. Why can the normal distribution be used in part (b),
even though the sample size does not exceed 30?
I believe this is because we are given the population
standard deviation sigma rather than the sample standard deviation. So we can
use the z test.
Answer:
4x - 2
Step-by-step explanation:
(2(3x-2))+(-2(x-1))
2(3x-2)-2(x-1)
2(3x-2-(x-1))
2(3x-2-<u>x</u><u>+</u><u>1</u><u>)</u>
<u>2</u><u>(</u><u>2x-1</u><u>)</u>
<u>4x-2</u>
