.______.
In a group of 150 people, 39 of them wear glasses. What is the probability of randomly selecting a person who does not wear glasses?
A. 111/150
B. 39/111
C. 111/189
D. 189/150
E. 39/150
Answer:
A. 111/150
Step-by-step explanation:
Because we know that 39 people out of the 150 in the group wear glasses, we need to subtract that from the total. This gives us 111 people that don't wear glasses.
Therefore, the probability of choosing someone not wearing glasses is 111/150.

Parallelograms PQRS and QRTU are standing on
the same base QR and between the same parallel
lines PT and QR. Prove that the area of
parallelograms PQRS and QRTU are equal.
Parallelograms PQRS and QRTU have the same base QR and height. it proves that areas are equal as base × height remains constant.
To prove that the area of parallelograms PQRS and QRTU are equal,
Use the concept that parallelograms with the same base and between the same parallel lines have equal areas.
Parallelograms PQRS and QRTU
Same base QR
Between the same parallel lines PT and QR
Proof,
Draw a diagram with parallelograms PQRS and QRTU sharing the common base QR and being situated between parallel lines PT and QR.
Since PQRS and QRTU share the same base QR and are between the same parallel lines PT and QR, their heights (perpendicular distances from base QR) are equal.
Let's call this height 'h'.
The area of a parallelogram is given by the formula:
Area = base × height.
For PQRS, its area would be: Area of PQRS = QR × h.
For QRTU, its area would be: Area of QRTU = QR × h.
Since both parallelograms have the same base 'QR' and the same height 'h', their areas are equal.
Therefore, it is proved that the area of parallelograms PQRS and QRTU are equal.

A scientist studied the migration patterns of two types of whales. The humpback whale traveled 2,000 miles in 25 days. The gray whale traveled 2,250 miles in 30 days. Assuming the humpback whale travels the same distance each day, what is the unit rate for the humpback whale in miles per day?
Answer:
it is 80 miles
Step-by-step explanation:
2000 divided by 25 is 80 therefore you multiply 80 x 30

please help
Answer:
-34.2
Step-by-step explanation:
when u multiply those 2 numbers, it makes -34.2
Answer: G = 35.2
Step-by-step explanation: G - 6 x 5.7 = 1
G - 34.2 = 1
G = 1 + 34.2
G = 35.2
G = 176/5 , G = 35 1/5
Can someone help me with these questions.
Answer:
C ( x = 2 (multiplicity of 2), x = -2, x = -4)
A ( x = 5 (crosses), x = -3 (touches))
Step-by-step explanation:
Here are a couple of rules that helped me come to these answers.
1. When finding a zero, you flip the value inside of the parenthesis. For example (x + 2) would have the zero of x = -2.
2.The multiplicity of something is how many times the same zero is there. It is the exponent outside of the equation. For the first question, the (x - 2) has an exponent of 2, thus it has the multiplicity of 2.
3. The multiplicity determines whether the line just touches (or "bounces" off) the x axis or crosses the x axis. If the multiplicity is odd, it crosses the axis. If the multiplicity is even, it just touches the axis. A good way to remember this is with linear and quadratic equations. A linear is commonly know as only having an exponent of 1 (an odd) number and would cross the x axis. A quadratic equation has an exponent of two (an even number) so the line "bounces" on a graph.
what is 9x2y-3 if x = 5 and y = 3.
Answer:
267
Step-by-step explanation:
increasing or decreasing?
slope?
y and x intercept?
other points the line goes through?
equation if the line?
Answer:
slope = 1/2
The x-intercept is (8, 0). The y-intercept is (-4, 0).
(2, -3), (4, -2), (6, -1)
y = (1/2)x - 4
Step-by-step explanation:
1)
slope = rise/run
Start at (0, -4) and go to (2, -3).
Start at (0, -4) and go 1 unit up. That is a rise of 1.
Now go 2 units right to arrive at (2, 3). That is a run of 2.
slope = rise/run = 1/2
2)
The line crosses the x-axis at (8, 0).
The x-intercept is (8, 0).
The line crosses the y-axis at (-4, 0).
The y-intercept is (-4, 0).
3)
Here are some points: (2, -3), (4, -2), (6, -1)
4)
y = mx + b
y = (1/2)x - 4
Answer:
Below in bold.
Step-by-step explanation:
The line is rising to the right so it has an increasing slope.
The slope of the line is 4/8 = 1/2.
Reading from the graph the x intercept is (8, 0).
The y-intercept is (0, -4).
The line passes through the points (2, -3) and (6, -1).
The equation of the line is:
y = (1/2)x - 4.

Step-by-step explanation:
Michael Fenton sells plumbing supplies to contractors. He earns 3% commission on the first $15,000
in sales, 5% on the next $15,000, and 8% on sales over $30,000. Last month he sold $52,000 worth
of plumbing supplies. What was his total commission?
Answer:
His total commission was: $2,960
Step-by-step explanation:
The commissions that Michael Fenton earns by selling plumbing supplies to contractors has three levels:
On the first $15,000 in sales, he earns 3%
On the next $15,000 in sales, he earns 5%
Over $30,000 in sales, he earns 8%.
Last month he sold $52,000 worth of plumbing supplies. His commissions will be calculated according to the levels reached:
The first $15,000 gave him 3%*15,000=0.03*15,000=$450
From the $52,000 sales, there remains $52,000 - $15,000 = $37,000 for the next levels.
The next $15,000 gave him 5%*15,000=0.05*15,000=$750
Now $37,000 - $15,000 = $22,000 remain for the last level.
Michael earned 8% of $22,000 = 0.08*22,000 = $1,760
His total commission was: $450 + $750 + $1,760 = $2,960
