Answer:
Degree of freedom = 798
Step-by-step explanation:
Given that,
First random sample, n₁ = 436
Second random sample, n₂ = 364
So,
Degree of freedom = n₁ + n₂ - 2
= 436 + 364 - 2
= 798
⇒Degree of freedom = 798
Answer:
y = -3x + 17
Step-by-step explanation:
In this question, you have to put the given equation into slope intercept form.
Slope-intercept form: y = mx + b
Solve:
y - 2= -3(x - 5)
Use the distributive property to distribute the -3 to the variables inside the parenthesis.
y - 2 = -3x + 15
Add 2 to both sides to get "y" by itself.
y = -3x + 17
The slope intercept form of the line would be y = -3x + 17
Answer:
$2.25
Step-by-step explanation:
18/8=2.25
STEP 1:
First we need both in the same unit of measurement.
1 pint= 2 cups
Convert 15 cups to pints:
=15 cups ÷ 2 cups per pint
=7.5 pints
STEP 2:
Find percentage:
=8 pints ÷ 7.5 pints
=1.0666 decimal percent of 8 pints
STEP 3:
Convert to %:
=1.06666 x 100
=106.66% percent 8 is of 7.5 pints
*TIP: if you know you're changing to a percentage from a decimal, you will always move the decimal two places to the right.
ANSWER:
8 pints is 106.66% of 7.5 pints.
Hope this helps! :)
