Answer:
3/8
Step-by-step explanation:
first year's work is 1/6
second year's work is 1/8
third year's work is 1/12
combining all 3 gives us
1/6 + 1/8 + 1/12
which simplifies to 3/8
The answer will be 10/3 also I'll recommend downloading photo math it really helps!! It's free.
Answer:
Null hypothesis: <em>H₀</em>: <em>p</em>₁ = <em>p</em>₂.
Alternate hypothesis: <em>H₀</em>: <em>p</em>₁ ≠ <em>p</em>₂.
Step-by-step explanation:
A statistical experiment is conducted to determine whether the proportions of unemployed and underemployed people who had relationship problems were different.
Let <em>p</em>₁ = the proportion of unemployed people who had relationship problems and <em>p</em>₂ = the proportion of underemployed people who had relationship problems.
A hypothesis test for difference between proportions, can be conducted to determine if there is any difference between the two population proportions.
Use a <em>z</em>-test for the test statistic.
The hypothesis test is:
<em>H₀</em>: There is no difference between the proportions of unemployed and underemployed people who had relationship problems, i.e. <em>p</em>₁ = <em>p</em>₂.
<em>Hₐ</em>: There is a significant difference between the proportions of unemployed and underemployed people who had relationship problems, i.e. <em>p</em>₁ ≠ <em>p</em>₂.
Functions like these are just mattress of plugging in.
Graph: y = 2x+3
Let's just take five numbers: -2, -1, 0, 1, 2
Make a table like the disclosed image, but replace the function at the top-middle with:
y = 2x + 3
Go through each equation by replacing the 'x' in each equation with the given number.
Example:
Number: -2
Function: y = 2x + 3
Plug-in: y = 2(-2) + 3
Simplify: y = -4 + 3
Simplify: y = -1
Repeat this with -1, 0, 1, and 2 to draw the function.
