Answer:the answer is 28 the second one.
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given
Required
Find n
Simplify (n + 1)!
Factorize
Divide both sides by n!
Open brackets
Collect like terms
Multiply both sides by -1
The following are the factors of 14xy⁴:
2, 7, 14, x, y, y², y³, y⁴, xy, xy², xy³, xy⁴, 2x, 2y, 2y², 2y³, 2y⁴, 2xy, 2xy², 2xy³, 2xy⁴, 7x, 7y, 7y², 7y³, 7y⁴, 7xy, 7xy², 7xy³, 7xy⁴, 14x, 14y, 14y², 14y³, 14y⁴, 14xy, 14xy², 14xy³
I did not list the original monomial, as we know it is a factor of itself.
= 4x - 11
x is the input, y is the output.
So if you want to know what input is needed to get an output of 10, set y to 10 and solve for x:
10 = 4x - 11
21 = 4x
x = 21/4
Answer: Std = 6.0
Step-by-step explanation:
Let us take a step by step process to solve this problem.
We have from the question that;
Population 1: 76 77 66 71 55 63 83 58
Population 2: 78 71 71 65 61 71 77 62
where n is no of occurrence = 8
taking the difference of P1 - P2 we have;
Difference (d) : -2 6 -5 6 -6 -8 6 -4
Total value of difference = -7
Difference squared (d₁ -d)² = 4 36 25 36 36 64 36 16
Total value of difference squared (d₁ -d)² = 253
The mean Σ = sum of values (d)/total value = -7/8 = -0.875
⇒ We are asked to find the value of the standard deviation of the paired difference.
Standard deviation is given as;
Std = √(Σ (Δd)² / n-1
Std = √[(253) / 8-1]
Std = √(253/7) = 6.0
Std = 6.0
cheers i hope this helped!!!!!!
