Lorena took a survey of the students in her honors science class to determine how many are going to college. She
found that 85% of the students plan to go to college
Can Lorena make the inference that 80% of all the seniors at her school are going to college? Check all that apply
O No, Lorena's sample was not a random sample of the entire school,
O No, to make a valid inference, Lorena would have to survey every senior
O No, Lorena's sample was biased because it was taken only from an honors class,
Yes, Lorena's sample was unbiased,
Yes, Lorena's inference would be correct

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
