➷ We have 2 points which we can use to figure out the slope
slope = difference in y values/ difference in x values
Substitute in the values you have:
0 - 5/ 3 - 0
slope = -5/3
The y intercept is simply where the line crosses the y axis
In this case, it is 5
Therefore, your equation is y = -5/3x + 5

Answer:
a) 0.778
b) 0.9222
c) 0.6826
d) 0.3174
e) 2 drivers
Step-by-step explanation:
Given:
Sample size, n = 5
P = 40% = 0.4
a) Probability that none of the drivers shows evidence of intoxication.
b) Probability that at least one of the drivers shows evidence of intoxication would be:
P(X ≥ 1) = 1 - P(X < 1)
c) The probability that at most two of the drivers show evidence of intoxication.
P(x≤2) = P(X = 0) + P(X = 1) + P(X = 2)
d) Probability that more than two of the drivers show evidence of intoxication.
P(x>2) = 1 - P(X ≤ 2)
e) Expected number of intoxicated drivers.
To find this, use:
Sample size multiplied by sample proportion
n * p
= 5 * 0.40
= 2
Expected number of intoxicated drivers would be 2
The answer is c( 1/81
Have a great day/night
Answer:
t=10
Step-by-step explanation:
3*(t+4)-2*(2*t+3)-(-4)=0
Step by step solution :
Step 1 :
Equation at the end of step 1 :
((3 • (t + 4)) - 2 • (2t + 3)) - -4 = 0
Step 2 :
Equation at the end of step 2 :
(3 • (t + 4) - 2 • (2t + 3)) - -4 = 0
Step 3 :
Equation at the end of step 3 :
10 - t = 0
Step 4 :
Solving a Single Variable Equation :
4.1 Solve : -t+10 = 0
Subtract 10 from both sides of the equation :
-t = -10
Multiply both sides of the equation by (-1) : t = 10

You have a 1/3 chance each spin.
1/3 = x/180
180 = 3x
x = 60
