Well if it rose 38 degrees all we need to do is 38-12 (because it was -12) and the answer to that is 26.
Te temperature at the end of the day was 26°
Answer: 52
Step-by-step explanation:
Formula for sample size:-
, where 
= population standard deviation.
= Two -tailed z-value for 
(significance level)
E= margin of error.
Given : tex]\sigma=\text{ 0.30 ounce}[/tex]
⇒Significance level for 99.6% confidence level :
By using z-value table ,Two -tailed z-value for 
:
E= 0.12 ounces.
Minimum sample size will be :-
Hence, the minimum sample size for the number of packages the inspector must select = 52
Answer:
Bottom left graph.
Step-by-step explanation:
I answered this by finding the y-int.
8(0) - 3y = 18
-3y = 18
y = -6
And it has a positive relationship so the line slants from bottom left to top right.
X = 1, 1/2, -3
The roots(zeros) are the x values where the graph intersects to the x-axis. To find zeros, replace y with 0 and solve for x
Answer:
Rebecca is incorrect. The equivalent quarterly interest rate is 1.75%.
Explanation:
The formula for compound interest is i = r/n.
r represents the interest rate in decimal form.
n represents the compounding periods in a year.
Calculate the interest rate for 7% compounded quarterly:
Since interest compounded quarterly is four times a year, n = 4.
7% is converted to decimal form by dividing by 100.
7 / 100 = 0.07
r = 0.07
Substitute these into the formula:
i = r/n
= 0.07/4
= 0.0175
0.0175 is in decimal form. To convert it to a percentage, multiply it by 100.
0.0175 X 100 = 1.75%
1.75% ≠ 2%
Therefore, Rebecca is incorrect. The equivalent quarterly interest rate is 1.75%.
