Answer:
x = 6
Step-by-step explanation:
0 = x^2 -12x + 36 solve by factoring ...or Quadratic Formula
0 = ( x-6)(x-6) shows zeroes ( both of them) are x = 6
Answer: 60
Step-by-step explanation: Okay, so 4 is approx 22.3 percent of 18, so 22.3 percent of 270 is approx 60. That's how I worked it out, please do tell if I am wrong.
Answer:
Lower limit = 0.76
Upper limit = 0.84
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 350
Number of drivers that buckle = 280
Formula:


The standard deviation for sp =

95% Confidence Interval:


Putting the values, we get,

Lower limit = 0.76
Upper limit = 0.84
Answer:
x=15
Step-by-step explanation:
Hey There!
So what we want to do is inverse operations from the formula of area of a triangle
The area is equivalent to

h=height
b=base
now we setup an equation with what we are given
we are given A (area) and h(height)
so the equation looks like...

now we solve for b (x)
step 1 multiply each side by 2
75x2=150
/2x2 cancels out
now we have
150=10b
step 2 divide each side by 10
150/10=15
10/10 cancels out
b=15
We can conclude that the base (aka x) is equal to 15
