Answer:
x=9
Therefore angles 7x-4 = 6x-4 = 59 degree
Step-by-step explanation:
7x-4 = 6x-4 Findings; alternate angles
Although any coefficient angles can be set = to each other.
7x-6x-4 = +5 Subtract 6x from both sides
x -4 = 5
x = 5+4 Add 4 to each side
x = 9
Find the angle degree
6(x) + 5 = 7(x) - 4 Plug 9 in to x
6(9) + 5 = 7 (9) - 4
54 + 5 = 63-4
59 = 59
x = 59 degree.
Thé vertex of the graph of the following function f(x)=x2+8x-2 is (-4,-18).
Answer: The probability is 0.4
Step-by-step explanation:
Since the time taken to assemble a car in a certain plant is a random variable having a normal distribution, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = time taken to assemble cars
µ = mean time
σ = standard deviation
From the information given,
µ = 20 hours
σ = 2 hours
We want to find the probability that a car can be assembled at this plant in a period of time less than 19.5 hours. It is expressed as
P(x < 19.5) = 1 - P(x ≤ 19.5)
For x = 19.5
z = (19.5 - 20)/2 = - 0.25
Looking at the normal distribution table, the probability corresponding to the z score is 0.4
