Answer:
I'm pretty sure the answer is A.
Step-by-step explanation:
A has the correct formula, all you have to do is plug in 8 for x. 1.03^8 = 1.26677008139. 1.26677008139 * 10 is 12.6677008139 which rounds up to 13.
I deeply apologize if that answer is wrong.
If this helped I would appreciate it if you marked me Brainliest. thank you and have a nice day!
Answer:
95% Confidence interval for y
= (-9.804, -5.979)
Lower limit = -9.804
Upper limit = -5.979
Step-by-step explanation:
^y= 2.097x - 0.552
x = -3.5
Standard error = 0.976
Mathematically,
Confidence Interval = (Mean) ± (Margin of error)
Mean = 2.097x - 0.552 = (2.097×-3.5) - 0.552 = - 7.8915
(note that x=-3.5)
Margin of Error is the width of the confidence interval about the mean.
It is given mathematically as,
Margin of Error = (Critical value) × (standard Error of the mean)
Critical value for 95% confidence interval = 1.960
Standard Error of the mean = 0.976
95% Confidence Interval = (Mean) ± [(Critical value) × (standard Error of the mean)]
CI = -7.8915 ± (1.960 × 0.976)
CI = -7.8915 ± 1.91296
95% CI = (-9.80446, -5.97854)
95% Confidence interval for y
= (-9.804, -5.979)
Hope this Helps!!!
Answer:
The exponent is 2, so the degree is 2
so it would be 8x13/8+13, which would simplify out to be 104/8+13 which would then simplify out even more to be 104/21 as a fraction or 4.95 as a decimal
hope this helps!! :) ❤❤❤❤
">" means results into or you can think about it as saying equals (=)
√75 = √5 * √15 > √5 * √5 * √3 > 5<span>√3
</span><span>√3
</span>√75 = √5 * √15 > √5 * √5 * √3 > 5√3
√3
Which then leads to..
5√3 + 5√3 + √3 + √3
