Slope = (7-3)/(5-2) = 4/3
<span>passes through the points (2,3) and (5,7).
so
y = mx + b
3 = 4/3(2) + b
3 = 8/3 + b
b = 3 - 8/3
b = 9/3 - 8/3
b = 1/3
equation
y = 4/3x + 1/3</span>
Answer:
y=27 and x=9
Step-by-step explanation:
the ratio is 4 to 3
Answer:A
Step-by-step explanation:
You use the equation:
m= (y2-y1) ÷ ( x2-x1)
m= (12-9) ÷ (2-1)
m= 3÷1
m= 3
Answer: H' : u = 24
Step-by-step explanation: Let H' represents the null hypothesis and H1 represents the alternative hypothesis.
From the question, the initial claim or assertion is that the machine is set to fill 24 ounces of cereal.
Hence H' : u = 24 ounces..... This is the null hypothesis.
After taking a sample of 100 boxes, they checked whether or not the machine is filling the boxes worn an average of 24 ounces of cereal.
This is the alternative hypothesis and is written as
H1: u ≠ 24 ( 2 tailed test)
Answer:
Step-by-step explanation:
Let n represent the number of friends who went to the movies with you.
Then ($12/ticket)n + $15 = $75. Solving for n, we get:
$75 - $15 $60
---------------- = ----------------- = 5 so a total of 5 friends went with you.
($12/ticket) ($12/ticket)
