Which of the following describe 86? Select all that apply.

Ber [7]

Answer:

A rational number is any number that can be written as a ratio of two integers (hence the name!). In other words, a number is rational if we can write it as a fraction where the numerator and denominator are both integers. ... Irrational, then, just means all the numbers that aren't rational.

Answer:

The calculated value t = 2.038< 2.145 at 0.05 level of significance

Null hypothesis is accepted

There is the average rate is less than μ ≤ 4

Step-by-step explanation:

Step(i):-

The Population of the mean 'μ' =4

sample size 'n' = 16

sample mean 'x⁻' = 4.53

given sample standard deviation 's' = 1.04

level of significance α = 0.05

Step(ii):-

Null hypothesis:H₀ : There is no significance difference between two means

Alternative hypothesis : H₁: There is significance difference between two means

Test statistic

$t = \frac{x^{-} - mean}{\frac{S}{\sqrt{n} } }$

$t = \frac{4.53-4}{\frac{1.04}{\sqrt{16} } }$

t = 2.038

Degrees of freedom ν = n-1 = 16-1 =15

t₀.₀₂₅ = 2.145

Conclusion:-

The calculated value t = 2.038< 2.145 at 0.05 level of significance

Null hypothesis is accepted

There is the average rate is less than μ ≤ 4

7 1/4x + x - 2 11/12x + 1 2/3x=5 3/5 find x

Bezzdna [24]

X= 4/5

Because...
You turn all the missed numbers in to improper fractions, then after you add all the ones with x’s after that you should get 7 then divide 7 by 28/5. Which equals 4/5
