Answer:
Each ticket cost $9.50
Step-by-step explanation:
4x+6.25=44.25
-6.25. -6.25
4x=38
x=9.50
<h3>
Answer: 0.3125</h3>
As a fraction, 0.3125 = 5/16
================================================
Work Shown:
n = 5 trials
p = 0.5 is the probability of landing tails
x = 3 = number of tails we want to happen
Use the binomial PDF formula to get
(n C x)*(p)^x*(1-p)^(n-x)
(5 C 3)*(0.5)^3*(1-0.5)^(5-3)
10*(0.5)^3*(0.5)^(2)
0.3125
note: flipping a single coin 5 times is the same as flipping 5 independent coins one time
Answer:
Folow these steps:
find the slope:
equation for slope: y2-y1 / x2- x1
4-2 / 4-1
2/3 is the slope
y=mx+b
y=2/3x+b
Now just plug in the x and y of either point into the equation. IM using (1, 2)
2=2/3(1)+b
2=2/3+b
b=1 1/3
Now that we have the y intercept and slope, construct the equation:
y=2/3x+1 1/3
Step-by-step explanation:
The angle is 64 because if srt is 26 then urt is also 26 because the kite is symmetrical. In a symmetrical kite the intersecting lines form right angles so we can say that urt +rus=90
So 26+ rus =90
Rus=64
