Answer:
The third option is correct
Step-by-step explanation:
We can rule out the first option because systems of equations CAN have decimal answers (this certain question cannot because of the domain) Same for the second option.
The last option says that all the numbers of forks knives and spoons must be equal but the question never specified that, in fact it looks like that is impossible since the variables have different coefficients.
The only logical answer is number 3
Answer: Isn't a circle always 360??
Step-by-step explanation:
The answer is 3.1 because 3.1*3.1 is 10.261
Answer:
99% confidence interval for the mean value from the random number generator is a lower limit of 85.87 and an upper limit of 110.93.
Step-by-step explanation:
Confidence interval = mean +/- margin of error (E)
mean = 98.4
sd = 16.3
n = 15
degree of freedom (df) = n - 1 = 15 - 1 = 14
confidence level (C) = 99% = 0.99
significance level = 1 - C = 1 - 0.99 = 0.01 = 1%
t-value corresponding to 14 df and 1% significance level is 2.977.
E = t×sd/√n = 2.977×16.3/√15 = 12.53
Lower limit = mean - E = 98.4 - 12.53 = 85.87
Upper limit = mean + E = 98.4 + 12.53 = 110.93
99% confidence interval for the mean is between 85.87 and 110.93
Answer:
No
Step-by-step explanation:
12ab + 18a
_________________________
a(16b + 24)
use the distributive property
16ab + 24a is not equal to 12ab + 18a
