makvit [3.9K]
I'm assuming you are talking about polynomials.

For example, I have x^2 + 2x + 1, and I want to add 2x^2 + x + 2

Then the like terms here are:

x^2 and 2x^2,  2x and x, 1 and 2, they are quadratic, linear and constant, respectively.

The length of time taken on the SAT for a group of students is normally distributed with a mean of 2.5 hours and a standard devi
son4ous [18]

Answer:

Step-by-step explanation:

Since the length of time taken on the SAT for a group of students is normally distributed, we would apply the formula for normal distribution which is expressed as

z = (x - u)/s

Where

x = length of time

u = mean time

s = standard deviation

From the information given,

u = 2.5 hours

s = 0.25 hours

We want to find the probability that the sample mean is between two hours and three hours.. It is expressed as

P(2 lesser than or equal to x lesser than or equal to 3)

For x = 2,

z = (2 - 2.5)/0.25 = - 2

Looking at the normal distribution table, the probability corresponding to the z score is 0.02275

For x = 3,

z = (3 - 2.5)/0.25 = 2

Looking at the normal distribution table, the probability corresponding to the z score is 0.97725

P(2 lesser than or equal to x lesser than or equal to 3)

= 0.97725 - 0.02275 = 0.9545

If the ratio of the measure of the complement of an angle to the measure of its supplement is 1:3, find the measure of the angle
prohojiy [21]
Set up and solve an equation:

3(90-x) = (180-x).  Then  270 - 3x = 180 - x, or   270 - 180 = 2x.
                                                                               90 = 2x, so x = 45 deg.

Is this true?     3(90-45) = (180-45)?  If so, x = 45 degrees is correct.
