If c = 4, then <span>200 − 10(4) = 200 - 40 = 160 < 150 (FALSE)
</span>if c = 6, then 200 − 10(6) = 200 - 60 = 140 < 150 (TRUE)
if c = 10, then 200 − 10(10) = 200 - 100 = 100 < 150 (TRUE)
if c = 12, then 200 − 10(12) = 200 - 120 = 80 < 150 (TRUE)
answer
4 does not satisfy <span>the inequality 200 − 10c < 150</span>
Answer:
K = $33
D = $75
E = $25
Step-by-step explanation:
k = kaitlin's $
d = 3(k - 8)
e = k - 8
k + 3(k - 8) + k - 8 = 133
k + 3k - 24 + k - 8 = 133
5k - 32 = 133
5k = 154
k = 33
dale's $ = 3(33 - 8) = 3(25) or $75
eric's $ = 33 - 8 = $25
Answer:
The coordinates of H are (-4,1).
Step-by-step explanation:
Answer:
1.2
Step-by-step explanation:
Given that X is Normally distributed random variable with an unknown mean μ and known standard deviation 6
Hence we can say for a sample of size 100, the sample mean will have a std deviation of =
Since population std deviation is known we can use Z critical value for finding out the confidence interval
For 95% using (68-95-99.7 rules) we have z critical value =2
Hence margin of error =2(std error) = 1.2
Confidence interval 95%
Lower bound = Mean - margin of error = Mean -1.2
UPper bound = Mean +1.2
Hence , 95% of all of these values of x should lie within a distance of __1.2___ from μ .
