Sorry, I don't know the answer.
The first thing to do is turn this into an equation:
2/3 ÷ 10
10 as a fraction is 10/1
2/3 ÷ 10/1 =
Fractional division is just fractional multiplication after switching the numerator and the denominator of the second fraction:
2/3 X 10/1
Fractional multiplication is simply multiplying the numerators by each other, and the denominators by each other:
2 X 10 = 20
3 X 1 = 3
20/3
Each piece of liquorice will be 20/3 or 6 2/3 of a yard long.
Answer:
|7 - n|
Step-by-step explanation:
Finding a difference means finding what that number is subtracted by another number, and then finding the absolute value of your result.
Assuming "a number" = n, the <u>difference</u><em> </em>of a number and 7 is |7 - n|
Answer:
a) 74.0353 < u < 74.0367
b) 74.036 < u
Step-by-step explanation:
Given:
- Sample size n = 15
- Standard deviation s.d = 0.0001 in
- Sample mean x_bar = 74.036
Find:
A) Calculate the 99% two-sided confidence interval on the true mean piston diameter.
Solution:
- For 99% CI, We have a = 0.01 , and Z_a/2 = 2.58
------> (x_bar - Z_a/2*s.d / sqrt(n)) < u < (x_bar + Z_a/2*s.d / sqrt(n))
------> (74.036 - 2.58*0.0001 / sqrt(15)) < u < (74.036 + 2.58*0.0001 / sqrt(15))
------> 74.0353 < u < 74.0367
Find:
B) Calculate the 95% one-sided lower confidence interval on the true mean piston diameter.
Solution:
- For 95% lower CI, We have a = 0.05 , and Z_a = 1.645
------> (x_bar - Z_a/2*s.d / sqrt(n)) < u
------> (74.036 - 1.645*0.0001 / sqrt(15)) < u
------> 74.036 < u
Good evening ,
Answer:
{(1,6),(2,2),(4,7),(3,2)}
Step-by-step explanation:
As a function , f has a unique image for each number of the domain.
for instance, the first set can’t represent a function because 1 has more than one image(number).
