x = 7, y = 16
Step-by-step explanation:
From the diagram shown;
2x+5 = x+12
collect the like terms
2x-x = 12 - 5
x = 7
Similarly, y - 4 = x+5
y-4 = 7+5
y - 4 = 12
y - 12+4
y = 16
hence x = 7, y = 16

Calculate the area of triangles using two different methods. figures are now drawn to scale.
Answers
Answer:
the formula is base times hight divided by two so use the formula to sovle the problem
Step-by-step explanation:
The area of the triangles given are 52.5 feet² and 369 inches² respectively.
What is Area?Area of a two dimensional shape is the total region which is bounded by the object's shape.
The basic formula to calculate the area of a triangle is,
Area = [tex]\frac{1}{2}[/tex] × base × height
1. Base = 12 + 3 = 15 feet
Altitude/height = 7 feet
Area = [tex]\frac{1}{2}[/tex] × 15 × 7 = 52.5 feet²
2. Calculating the area of two separate triangles and then adding it,
Area = ([tex]\frac{1}{2}[/tex] × 32 × 18) + ([tex]\frac{1}{2}[/tex] × 9 × 18)
= 288 + 81
= 369 inches²
Hence the area of the two figures is 52.5 feet² and 369 inches² respectively.

78% of drivers use their turn signal. Part A: What is the probability that exactly 3 drivers use their turn signal if a police officer pulls over five drivers? (5 points) Part B: What is the probability the next driver using their turn signal that the police officer pulls over if the fifth driver? (5 points) (10 points)
Step-by-step explanation:
p = 0.78
1 - p = 0.22
P(x = 3)
Using the binomial distribution formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
P(x = 3) = 5C3 * 0.78^3 * 0.22^2
P(x = 3) = 10 * 0.78^3 * 0.22^2
P(x = 3) = 0.2297
