I supposed you mean add the equation h + 3 to 6h + 1?
6h + 1 + h + 3 = 7h + 4
But if you mean subtract the equation h + 3 from 6h + 1
6h + 1 - (h + 3) = 6h + 1 - h - 3 = 5h - 2
Answer:
slope = 7 and point = (3, 7)
b = y - slope*x
b = 7 -7 * 3
b = -14
Then we enter "b" and the slope into this equation:
y = 7x -14
Step-by-step explanation:
Answer:
a) Sample size need to be greater than 30
b) The probability is approximately 0.0571
Step-by-step explanation:
a) For a normal distribution, the sample size has to be greater than 30. A sample size greater than 30 makes it to be an approximate normal distribution.
b) Given that:
μ = 11.2 minutes, σ = 4.5 minutes, n = 35
The z score determines how many standard deviations the raw score is above or below the mean. It is given by:
For x < 10 minutes
Therefore from the normal distribution table, P(x < 10) = P(z < -1.58) = 0.0571
The probability is approximately 0.0571
Well, you need the equationL: <span>y=3+<span>√x−8</span></span>. than order to find the inverse function, we have to switch the variables x and y and then solve for y..
If
then
and
.
You can match points:
if x=0, y=0
if x=3, y=1
if x=-3, y=1
if x=6, y=4
if x=-6, y=4
