The given data can be tabulated as:
Number of swimsuits, s (x) Price, p (y)
0 0
2 23
4 46
6 69
8 92
10 115
We can see that by looking alone, the value of price p is
increasing at a constant rate of 23 therefore the equation relating s and p
must be linear in the form of:
y = m x + b
or
p = m s + b
where m is the slope of the line and b is the y intercept
The slope m can be calculated using the formula below and
any two data points:
m = (y2 – y1) / (x2 – x1)
m = (23 – 0) / (2 – 0)
m = 11.5
The value of b (y-intercept) is the value of y when x =
0, therefore b = 0
The whole equation then becomes:
p = 11.5 s
Answer:
.075 or 7.5% chance
Step-by-step explanation:
add up the number of balls to get 20. The chance of getting orange is 1/2 or .5, and the chance of getting yellow is 3/20, or .15. Then multiply the two fractions.
50lb = 117.50
1lb = 2.35 per pound
Answer:
D 28x+40
Step-by-step explanation:
To find the perimeter, we add all the sides
2x+2x+5x+8+4x+10+5x+8+x+2+2x+7x+12 = P
Combine like terms
2x+2x+5x+4x+5x+x+2x+7x+10+8+8+2+12
28x +40
Answer:
Part A
Each time you press F9 on your keyboard, you see an alternate life for Jacob, with his status for each age range shown as
either alive or dead. If the dead were first to appear for the age range of 75 to 76, for example, this would mean that Jacob
died between the ages of 75 and 76, or that he lived to be 75 years old.
Press F9 on your keyboard five times and see how long lacab lives in each of his alternate lives. How long did lacob live each
time?
