This can solved using the cosine law which is:
c² = a² + b² - 2ab cos θ
Using the values given from the problem
6² = b² + b² - 2bb cos 112.62
And solving for b
36 = 2b² - 2b² cos 112.62
b = 3.6
The answer is the 3rd option.
50 X (40 X$20) = 50 X $800 = $40,000
15 X (4 X (50% X $20+ $50)) = 15 X (4 X $60) = 15 X 240 = $3600
$40,000 + $3600 = $43,600 Total payroll
$3,600/$43,600 = .0825688073 as a percent rounded to the nearest tenth is 8.3%
To figure this question out, we first need to figure out how much one pound of potatoes costs. To do this, we need to divide 18 by 8, and in this, we get $2.25. Then, we have to multiply this by 15 to find out how much 15 pounds of potatoes costs. This gives us $33.75, which is our answer to this question.
Complete Question
It has been found from experience that the mean breaking strength of a particular brand of thread is 9.72 oz with a standard deviation of 1.4 oz. Recently a sample of 36 pieces of thread showed a mean breaking strength of 8.93 oz. Can one conclude at a significance level of (a) 0.05, (b) 0.01 that the thread has become inferior?
Answer:
At both and the conclusion is that the thread has become inferior
Step-by-step explanation:
From the question we are told that
The population mean is
The standard deviation is
The sample size is n = 36
The sample mean is
The null hypothesis is
The alternative hypothesis is
Generally the test statistics is mathematically represented as
=>
=>
So
The p-value obtained from the z- table is
So at
So we reject the null hypothesis,hence we conclude that the thread has become inferior
So at
So we reject the null hypothesis,hence we conclude that the thread has become inferior
