Answer:
E) we will use t- distribution because is un-known,n<30
the confidence interval is (0.0338,0.0392)
Step-by-step explanation:
<u>Step:-1</u>
Given sample size is n = 23<30 mortgage institutions
The mean interest rate 'x' = 0.0365
The standard deviation 'S' = 0.0046
the degree of freedom = n-1 = 23-1=22
99% of confidence intervals 
(from tabulated value).
using calculator
Confidence interval is
the mean value is lies between in this confidence interval
(0.0338,0.0392).
<u>Answer:-</u>
<u>using t- distribution because is unknown,n<30,and the interest rates are not normally distributed.</u>
Answer:
4/3π - √3
Step-by-step explanation:
Pie piece of circle is area of circle x portion of circle
πr²*x/360 = π(2)²*120/360 = 4/3π
Then you must subract the non-right triangle area
1/2ab sin C = 1/2(2)(2) sin 120 = 2 * √3/2 = √3
4/3π - √3
Answer:
the answer is ice cream parlor and town hall
Step-by-step explanation:
because if you for 3 times right and 3 times up from ice cream parlor it will land to town hall
Answer: See explanation
Step-by-step explanation:
You didn't state the sentences but let me help out based on the information given.
Number of new motion toys = 12
Number of batteries used by each toy = 3
Since N represents the total number of batteries he need, the value of N will be:
= Number of toys × Number of batteries used by each toy
= 12 × 3
= 36
That means N equals 36.
Answer:
C. $16.00
Step-by-step explanation:
First, let's find how much they profit from one loaf
The profit is the difference between how much they sell it for and what they buy it for.
So, we can subtract what they buy the bread for from how much the sell it for
selling price-buying price
2.40-0.80=1.6
So, they profit $1.60 per loaf
To find how much they profit for 10 loaves, multiply their profit from one loaf by 10
profit*10
1.60*10=16
The profit for 10 loaves is $16, or choice C
