I got 2.5
{(6.6+x)/.7}x6 = 78
=39.6 + 6x = 54.6
= 2.5
Answer:
w = 4 m
Step-by-step explanation:
The volume (V) of a cuboid is
V = lwh ( l is length, w is width and h is height )
Given V = 144 m³, then
lwh = 144 ( substitute l = 3 and h = 12 )
3 × w × 12 = 144
36w = 144 ( divide both sides by 36 )
w = 4
Answer:
49 eggs.
Step-by-step explanation:
The formula for Margin of Error =
z × standard deviation/√number of samples
z = z score of 98% confidence interval = 2.326
Margin of Error = Half a day = 1/2day = 0.5 day
Standard deviation = 1.5 days
Number of samples = number of eggs he needs to sample = unknown.
Imputing these above values into the formula
Margin of Error = z × standard deviation/√number of samples
0.5 = 2.326 × 1.5/√n
Cross Multiply
0.5 × √n = 2.326 × 1.5
√n = 2.326 × 1.5/0.5
√n = 3.489/0.5
√n = 6.978
Square both sides
(√n)² = 6.978²
n = 48.692484
n ≈ Approximately to the nearest whole number = 49
Therefore, the number of eggs he needs to sample to create the desired interval is approximately to the nearest whole number 49 eggs
1.Given, x={p,q}.
Now, possible subsets of x are ϕ,{p},{q},{p,q}.
2.if A = fa b, c. d, e and B of a, e, i, o, u. list the elements of B - A and also show it in a venn diagram by
shading
hope it helps
merryyyy Christmassss
