Since he knocks at least 6 pins 70% of the time.
For 200 rolls:
70% of 200
= (70/100) * 200
= (7/10) * 200
= 140
140 times.
hope this helps :)
Step-by-step explanation:
x = number of visits
y = number of earned points
the equation for the situation is (remember the 20 points starting balance) :
y = 5.5 × x + 20
and the question is now actually after how many visits she reached 75 earned points.
therefore,
75 = 5.5 × x + 20
55 = 5.5 × x
x = 55/5.5 = 10
she gets a free movie ticket after 10 visits.
0.81 = 81/100
0.5 = 5/10 = 1/2
0.63 = 63/100
0.214 = 214/1000 = 107/500
X=10 and y=20 is the answer
Answer:
y equals three sevenths times x plus 3
Step-by-step explanation:
Given the information:
- points going up from about zero comma negative 3
<=> Let A (x1, y1) = (0, -3)
- to the right to about 7 comma zero
<=> Let B (x2, y2) = (7, 0)
As we know, the line of best fit is a linear equation that represent the data with the standard form:
y = mx + b where:
- m is the slope
- b is the the y-intercept when x = 0
For a line that goes trough the points (x1, y1) and (x2, y2), the slope is
m =
In this situation, we have:
m = =
=> y = x + b.
Because the line goes through A (0, 3)
=> 3 = *0 + b
<=> b =3
=> y = x + 3
So we choose y equals three sevenths times x plus 3
