4,968 dollars you just have to multiply 72 x 69
Answer:
There is insufficient evidence to support the claim.
Step-by-step explanation:
What we need to do is calculate the z factor and see whether or not we can refute the manufacturer's claim.
We have to:
z = (p - pm) / [pm * (1-pm) / n] ^ (1/2)
where p is the probability of the random sample, 13% or 0.13 and pm the probability per microwave maker, that is, 10% or 0.1. n sample size which is 57.
When replacing, we are left with:
z = (0.13 - 0.1) / [0.1 * (1-0.1) / 57] ^ (1/2)
z = 0.75
This value corresponds in the normal distribution to 0.7734 (attached image), this value is very large to refute the above, it must give a value less than 0.05 to be able to be refutable.
Therefore there is insufficient evidence to support the claim.
19
418 divided by 22 is equal to 19
2. 4= 2², so neighboring perfect squares should look like 1² and 3²
1² 2² 3²
1 4 9
3. 16 = 4², so neighboring perfect squares are 3² and 5²
3² 4² 5²
9 16 25
4. 169 = 13²
12² 13² 14²
144 169 196
5. 9 = 3²
2² 3² 4²
4 9 16
6. 25 = 5²
4² 5² 6²
16 25 36
7. 49 = 7²
6² 7² 8²
36 49 64
Answer:
Option 2
Step-by-step explanation:
If you multiply 2 by 2 you get 4. If you multiply 3 by 2 you get 6. If you multiply 4 by 2, you get 8. If you multiply 5 by 2 you get 10. A proportional relationship is where you can multiply all the numbers by a certain number to get the answer. In this case, all the numbers in the left column could get multiplied by 2 to get the number in the right column.
