IQ scores are normally distributed with a mean of 100 and a standard deviation of 15. Out of a randomly selected 750 people from the population, how many of them would
have an IQ less than 95, to the nearest whole number?

Rewrite the hyperbolic equation 4y^2 -9x^2 +54x-8y-113=0

Two lines that do not intersect are skew. always sometimes or never

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
