Answer:
y = -3x + 14
Step-by-step explanation:
y=x/3−1
The slope of the perpendicular line is the reciprocal of the given equation.
Given is 1/3x. Perpendicular slope is m=-3x
Substitute the perpendicular slope and the point (4,2) in an equation
y = mx + b
2 = -3(4) + b
2 = -12 + b
Find b by isolating
b = 2+12
b = 14
Substitute the slope -3x and b=14 to find the equation of the line.
y = mx + b
y = -3x + 14
Answer:
is it 0????????
Step-by-step explanation:
Answer:
1) Each group is composed of 10 people. They either saw results or don't saw results.
saw results no results Total
A 6 4 10
B 7 3 10
C 5 5 10
D 4 6 10
Total 22 18 40
Probability of a group seeing results:
Group A: 6/10 = 0.6
Group B: 7/10 = 0.7
Group C: 5/10 = 0.5
Group D: 4/10 = 0.4
Probability of a group not seeing results:
Group A: 4/10 = 0.4
Group B: 3/10 = 0.3
Group C: 5/10 = 0.5
Group D: 6/10 = 0.6
2) Groups A and B received the Power Pill.
What is the probability that a person saw results, given they received the power pill?
(6+7)/20 = 0.65
Groups C and D received the placebo.
What is the probability that a person saw results, given they received a placebo?
(5+4)/20 = 0.45
3) What is the probability that a person received the placebo, given they did not see results?
(5+6)/18 = 0.61
What is the probability that a person received the power pill, given that they did not see results?
(3+4)/18 = 0.39
Based on the information given and the computation, the height of the goalpost will be 16.10 meters.
<h3>
Solving the equation.</h3>
Let the height of the goalpost be represented by x.
Based on the information given, the equation to solve the question will be:
1.55/1.15 = x/11.95
Cross multiply
1.55 × 11.95 = x × 1.15
x = (1.55 × 11.95) / 1.15
x = 16.10
Therefore, the height of the goalpost will be 16.10 meters.
