Answer:
1. 65536
2. 458752000
Step-by-step explanation:
2 to the power of 16 is 65536
458752000=65536*7000
(a is the length of the side of each edge of the cube)<span>In words, the surface area of a cube is the area of the six squares that cover it. The area of one of them is a*a, or a<span> 2</span> . Since these are all the same, you can multiply one of them by six, so the surface area of a cube is 6 times one of the sides squared.</span>
The mean of the estimates is seconds, and the standard deviation of the sample is about . Then the test statistic is
where is the mean under the null hypothesis. So
We go on to find
so the difference is statistically significant and you reject the null hypothesis.
Answer:
C. The greatest common factor was not factored out correctly from second group
Step-by-step explanation:
The following lines show the process of factorization by using common factor.
<u>Line 1:</u>
In line 1, the equation is given and is grouped from which common factors can be taken. This is completely fine.
The only thing missing was equate to zero, but the options below talk about correct factors only, therefore this can't be considered as a mistake and can be ignored completely.
<u>Line 2:</u>
In line 2, the common terms are taken out from groups. The common term x is taken from group 1 which is fine. In second group the common term -y is taken out, which is fine but it was not factored out correctly. The correct factorization would have been:
which is different from what is given in line 2.
Options:
A. The grouping is correct in line 1. So this option is does not hold.
B. Common factor was factored correctly from group 1. So this option does not hold.
C. Common factor was not factored correctly from group 2. So this option holds and is correct. Thus we choose this option as correct answer.
D. There is a mistake. So this option is also not correct.
