Answer: 6
Step-by-step explanation:
Since Pam has 4 yards of fabric and she needs 2/3 yards of fabric for each curtain, the number of curtains that Pam can make with the fabric she has will be the total yards of fabric that she has divided by the fabric needs for each curtain. This will be:
= 4 ÷ ⅔
= 4 × 3/2
= 6
Therefore, she will make 6 curtains
Answer:
common denominator of 1/a + 1/b is ab
however simplifying the complex fraction gives: (b-a)/(b +a)
Step-by-step explanation:
common denominator of 1/a + 1/b
should be the product of the denominators
a*b
so 1/a + 1/b = (b + a)/ab
ao
( 1/a - 1/b) divided by (1/a + 1/b) = (b - a)/(ab) divided by (b+a)/ab
Answer:
99% one-sided lower confidence bound = 26.77
Step-by-step explanation:
We have to calculate a 99% one-sided lower confidence bound for the population variance.
The sample size is n=25.
The degrees of freedom are then:
The critical value of the chi-square for this confidence bound is:
Then, the lower confidence bound can be calculated as:
