Choco-Chippy Cookie Company has two different manufacturing plants. Company officials want to test whether each plant fills the

bags with the same number of ounces. A random sample of cookie bags from plant A had a mean of 24.2 ounces in each bag. A random sample from plant B had a mean of 22.2 ounces. They randomized the data over 100 trials, and the difference of means for each trial is shown in the dot plot below. What can Choco-Chippy Cookie Company conclude from this study?
A)The difference is significant because a difference of 2.0 is very likely.
B)The difference is significant because a difference of 2.0 is not very likely.
C)The difference is not significant because a difference of 2.0 is very likely.
D)The difference is not significant because a difference of 2.0 is not very likely.

Answer:

The correct answer is D

Step-by-step explanation:

The difference is not significant because a difference of 2.0 is not very likely.

If we see the dot plot shown, we can see that the variation is not likely to be 2.0 because at most dots points the difference is not close to 2. Its either 3,4 or 1. The difference would only be significant if 2.0 was likely. Hence, option D is correct.

How to answer this on descending powers of x please help pretty please
zheka24 [161]

Answer:  25x² - 64

<u>Step-by-step explanation:</u>

  (5x + 8)(5x - 8)

=        5x(5x - 8)   +    8(5x - 8)

=      25x² - 40x    +    40x - 64

=      25x²         + 0x           - 64

=              \large\boxed{25x^2-64}

NOTE: descending powers means the biggest exponent goes first, then the next biggest exponent, etc.

For example: x⁴ then x³ then x² then x then the number (which is actually x⁰)
