Answer:
D
Step-by-step explanation:
To get the graph, we will need to solve each inequality differently
For the first one, we have that
x/4 < -1-7
x/4 < -8
x < -8 * 4
x < -32
For the second side;
2x-1 ≥ 9
2x ≥ 10
x ≥ 5
So we have two arrows facing different directions
On the left should be unshaded while the right hand side should be shaded
So, the correct answer here is the 4th option
It will be C. Hope this helps! Mark brainly please!
Answer:
The probability that none will have high blood pressure is 0.0281
Step-by-step explanation:
The correct question is as follows;
Twenty percent of Americans ages 25 to 74 have high blood pressure. If 16 randomly selected Americans ages 25 to 74 are selected, find each probablility. a. None will have high blood pressure
This is a binomial problem. We shall solve in that line
The probability of success is 20% or 0.2 [(Americans ages 25 to 74 have high blood pressure)] p = 0.2
The probability of failure q is thus 1-p = 1-0.2 = 0.8
The probability of none is thus;
P(X= 0) = 16C0 p^0 q^16
= 16C0 * 0.2^0 * 0.8^16 = 0.0281
Answer:
undefined
Step-by-step explanation:
To find the slope of the line between two points, use the slope formula
.
and
represent the x and y values of one point the line passes through, and
and
represent the x and y values of another point the line also passes through. Therefore, use the x and y values of the points (0,3) and (0,4) to find the slope. Substitute them into the formula in the right order:
However, we can't divide 1 by 0. Therefore, the slope is undefined. (You could also graph the points to see that they form a vertical line, and all vertical lines have an undefined slope.)
