54
79
Answer:
I believe it is 47 degrees
Step-by-step explanation:
Triangles add up to 180 degrees
54 + 79 = 133
180 - 133 = 47
Ten samples of coal from a Northern Appalachian source had an average mercury content of 0.242 ppm with a standard deviation of 0.04 ppm. Find a 95% confidence interval for the mean mercury content of coal from this source. Round the answers to four decimal places.
Answer:
0.2172<x<0.2668
Step-by-step explanation:
The formula for calculating the confidence interval is expressed as;
CI = xbar ± (z*s/√n)
xbar is the average = 0.242ppm
z is the z score at 95% confidence = 1.96.
s is the standard deviation = 0.04pm
n is the sample size = 10
substitute the values into the formula;
CI = xbar ± (z*s/√n)
CI = 0.242 ± (1.96*0.04/√10)
CI = 0.242 ± (1.96*(0.04/3.1623))
CI = 0.242 ± (1.96*(0.01265))
CI = 0.242 ± (0.02479)
CI = (0.242-0.02479, 0.242+0.02479)
CI = (0.2172, 0.2668)
Hence a 95% confidence interval for the mean mercury content of coal from this source is 0.2172<x<0.2668.

What should the mean diameter, in inches, be in order to minimize the fraction of bearings that are scrapped?
Answer:
hello your question is incomplete attached below is the missing part of the question
answer : 3.000 inches
Step-by-step explanation:
In order to minimize the fraction of bearings that are to be scrapped The mean diameter in inches should be 3.000 inches and this is because the diameter of the bearings follows a normal distribution.
The higher the fraction of accepted bearings, the minimal the fraction of rejected fraction bearings
specifications of bearing diameter; 3.000 ± 0.002

G borrowed $15,000 to buy a business. The interest
rate was 11%. If G paid all the interest and the amount
borrowed with a single payment at the end of 16
months, what is the amount of this payment?
a. $16,650
b. $16,925
c.$17,200
Answer:
the answer is 17,200 that s the answer need anything else please cantact me
Amount of this payment is $17,200 so, option "C" is the correct answer to the following question.
Interest and payment based question:What information do we have?
Amount borrow = $15,000
Rate = 11%
Number of month = 16 months = 16 / 12 year = 1.333 year
Amount of payment = P(1 + r)ⁿ
Amount of payment = 15000(1 + 0.11)¹°³³
Amount of payment = 15000(1.1492)
Amount of payment = $17238
Amount of payment = $17,200 (Approx.)

A mother is 30 years old when her daughter is 4. In how many years will the daughter’s age be half the mother’s age?
Answer:
in 11 years
Step-by-step explanation: half of 30 is 15 and 11 + 4 is 15.
Step-by-step explanation:
Ok, if the mother is 30, then half her age would be 15. Now, if the daughter is 4, you would subtract 15-4, which equals 11.
