Answer:
C (-2, 0)
Step-by-step explanation:
y = x+2
intersect the x-axis when y = 0, then
0 = x+2
x = -2
Ten: 60
Hundred: 900
Thousand: 4000
Ten thousand: 60000
Answer:
-13
Step-by-step explanation:
-21 = k - 8
so we need to get k by itself so we will add 8 to both sides
-21 (+8) = k - 8 (+8)
-13 = k
Answer with explanation:
Given : Sample mean =
Standard deviation :
Sample size : n = 36
Claim :
∴
Since the alternative hypothesis is two tail , then the test is two tail test.
By using a z statistic and a 0.05 level of significance. Reject if z < -1.960 or is z> 1.960.
Then , the test static for population mean is given by :-
We reject since . We have statistically significant evidence at to show that the mean amount of garbage per bin is not different from 50.
Answer:
Infinitely many
Step-by-step explanation:
The second equation is basically multiplying the first equation by 2, so this means that they will have the same rate of change and initial value. Therefore, there are infinitely many solutions.
