Answer:
the length of a side of a square is 5 cm long.
Answer: 3 11/20
Step-by-step explanation:
You would first simplify 3 3/4 which is 15/4 then you would subtract it with 1/5
Next, you would have to find the GCD ( greatest common factor) for 15/4 and 1/5 which is 20 so multiply 15 by 5 and 4 by 5 which is 75/20, then multiply the top and bottom with 4 for 1/5 which is 4/20 . You then would subtract the simplified forms 75/20 with 4/20 Which is 71/20 which u can simplify to
3 11/20.
It's like saying 6(x+4)=x-11.
A. The point estimate of μ1 − μ2 is calculated using the value of x1 - x2, therefore:
μ1 − μ2 = x1 – x2 =
7.82 – 5.99
μ1 − μ2 = 1.83
B. The formula for
confidence interval is given as:
Confidence interval
= (x1 –x2) ± z σ
where z is a value
taken from the standard distribution tables at 99% confidence interval, z =
2.58
and σ is calculated
using the formula:
σ = sqrt [(σ1^2 /
n1) + (σ2^2 / n2)]
σ = sqrt [(2.35^2 /
18) + (3.17^2 / 15)]
σ = 0.988297
Going back to the
confidence interval:
Confidence interval
= 1.83 ± (2.58) (0.988297)
Confidence interval
= 1.83 ± 2.55
Confidence interval
= -0.72, 4.38
Answer:
(0,7) and (2,4) go to slope =-3/2
(1,-3) and (-1,-3) go to zero slope
(0,0) and (2,1) go to slope =1/2
(0,-1) and (2,-5) go to slope =-2
and (-1,3) and (-1,-3) go to no slope
