Answer:
y = (1/2)x + 2, in which 1/2 represents a fraction.
Step-by-step explanation:
Remember your formula y = mx + b; where m is the slope, and b is the y-intercept.
Now, simply look for the y-intercept (should be 0, 2), and plug in the x value in for the b.
The equation is now y = mx + 2.
For the next part, you'll find the slope; forewarning is that it doesn't matter how you do it, as long as you do it right. You can either use the slope formula, but I like to do rise over run. They're the same thing. If you don't know what rise over run is, look it up, it's pretty easy to understand. If not just do the slope formula.
Anyways, you need to grabs two different points that plot on the line; let's say (0, 2) and (2, 3). If you do the formula it should be (3 - 1) / (2 - 0). This will get you your 1/2.
Plug that into m, and your formula should be y = (1/2)x + 2, where 1/2 is a fraction.
Answer:
85.56% probability that less than 6 of them have a high school diploma
Step-by-step explanation:
For each adult, there are only two possible outcomes. Either they have a high school diploma, or they do not. The probability of an adult having a high school diploma is independent of other adults. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
50% of adult workers have a high school diploma.
This means that
If a random sample of 8 adult workers is selected, what is the probability that less than 6 of them have a high school diploma
This is P(X < 6) when n = 8.
In which
85.56% probability that less than 6 of them have a high school diploma
Answer:
Cylinder, A = 2π • w • h + 2π • w to the second power square units
Step-by-step explanation:
A right circular hollow cylinder is a 3D region enclosed by two right circular cylinders having the same axis and two parallel annular bases perpendicular to the cylinders' common axis which will be formed when you rotate the given by 360 degrees.

Answer:
(d) 428,820,000 pounds of garbage
Step-by-step explanation:
Your calculator or spreadsheet can give you the product of two numbers expressed in scientific notation.
(1.643×10^3 lb/resident) × (2.61×10^5 residents) = 4.28823×10^(3+5) lb
≈ 428.82×10^6 lb
= 428,820,000 lb . . . of garbage
