Step-by-step explanation:
Let us briefly explain the terms
- Variable: This is the letter in the expression
- Coefficient: This is the number beside the letter above
- Constant: This is a number without any variable attached.
Let us take our expression with two terms to be: 3x+5
Coefficient =3
Variable =x
Constant =5
The word phrase of the expression is:
5 added to the product of 3 and a number.
Answer:
123
Step-by-step explanation:
-7 + 4(n-1). Use this and plug in 10 for n, making it
-7 + 4(9)
-7+36
29

Answer: n = 600.25 ≈ 601 ( sample size)
the minimum sample size of the adults in United State who have sleep deprivation is 601
Step-by-step explanation:
Given that;
the confidence level = 95% = 0.05
the Margin of error E = 4% = 0.04
∴ level of significance ∝ = 1 - C.L
∝ = 1 - (95/100)
= 0.05
Z∝/2 = 0.05/2 = 0.025
Z-critical value at 95% confidence level is OR level of significance at 0.025 = 1.96 (z-table)
Now to calculate the sample size, we say
n = (Z(critical) / M.E )² P ( 1 - P)
now we substitute
n = (1.96 / 0.04)² × 0.5 ( 1 - 0.5)
n = 2401 × 0.5 × 0.5
n = 600.25 ≈ 601
Therefore the minimum sample size of the adults in United State who have sleep deprivation is 601
