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.

Jane builds toy trains that have 5 train
cars each. She uses 20 train cars in all.
How many toy trains does Jane make?
toy trains
Answer:
Here's how to solve it.
Step-by-step explanation:
Okay,
from what I understand she has 20 train cars total.
She uses 5 for each train.
So to solve you use simple division.
20 / 5 = 4
To check your answer substitute 4 in the equation so 4 × 5 does equal 20.
So it would be 4.
Line A has a slope of −3 . Line B has a slope of 4. Line C has a slope of 2
Which Line Is The Closest To Being Horizontal?
- Line A
- Line B
- Line C
- I dont Know
The line whose absolute value of the slope is least will be the slope which is close to being horizontal. Hence, line C is the answer.
An horizontal line has will have a slope value of 0. Hence, the steeper the slope, the greater the absolute value of the slope obtained. This means that a line deviates more from being horizontal as the absolute value of the slope increases.Therefore, the line with least absolute value would be the closest to being horizontal, hence, line C with an absolute value of 2.

aluminum, inc. produces cams at a rate of 0.04 per hundredth of a second. how many cans can be produced in a 7-hour day?
Answer:
Step-by-step explanation:
100800
1008 can s can be produced in a 7 hour day.
What is per thousands of a second ?Just divide 1 second by 1000 which is 0.001 secs.It can also be called as 1 millisecond.
According to the given question aluminium, inc. produces cams at a rate of 0.04 per hundredth of a second. this can be numerically expressed as
0.04 cans produced in 0.01 seconds.
We know 7 hour is = (7×3600) seconds which is = 25200 seconds.
∴ In 7 hours aluminum, inc. can produce (25200 × 0.04) which is
= 1008 cans.

Solve this equation algebraically.
Write both sides as powers of 16:
[tex]\log_4(2-x)=\log_{16}(13-4x) \implies 16^{\log_4(2-x)}=16^{\log_{16}(13-4x)}[/tex]
Since 16 = 4², we can rearrange the left side to get
[tex]16^{\log_4(2-x)}=(4^2)^{\log_4(2-x)}=4^{2\log_4(2-x)}=4^{\log_4(2-x)^2}[/tex]
Then, recalling that [tex]b^{\log_ba}=a[/tex], we have
[tex]4^{\log_4(2-x)^2}=16^{\log_{16}(13-4x)}\implies(2-x)^2=13-4x[/tex]
Now solve for x :
[tex](2-x)^2=13-4x[/tex]
[tex]4-4x+x^2=13-4x[/tex]
[tex]x^2-9=0[/tex]
[tex](x+3)(x-3)=0[/tex]
[tex]\implies x=-3\text{ or }x=3[/tex]
Notice that if x = 3, then log₄(2 - x) = log₄(-1) is undefined, so we throw out this solution. We don't run into this problem with x = -3, so that's the only (real) solution.
what is the slope or the line going through (0,0) (6,8) A: -6/8 B: -3/4 C: 3/4 D: 8/6

D: 8/6
Step-by-step explanation:
Slope = y 2 - y 1

Answer: D. 8/6
Step-by-step explanation:
To solve this, we can use the slope formula, which is
[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex] ← this is [tex]\frac{rise}{run}[/tex]
Plugging in the values of the two points, we get:

The following are rules for repeating patterns. For which rule will the 12th shape be a circle?
A. Triangle, Circle,Square
B. Circle, Square
C. Rectangle,Circle
Circle, Circle, Triangle
The third pattern because you can divide 12 by the number of shapes in the sequence and start counting from the remainder.
In this case choice C has 5 shapes. 12/5 is 2, with a remainder of 2.
The second term in choice C is Circle, so choice C is the answer.
Of course, you can also list them all out.
If there is no remainder when you divide then the 12th term is the last term in the sequence.

A motorboat heads upstream a distance of 24 miles on the Guadalupe River, whose current is flowing at 3 miles/hour. Which expression can represent the total time it takes to complete a round-trip up and back, where b is the speed of the boat in miles/hour?
Answer:
24/b-3 + 24/b+3
Step-by-step explanation:
For PLATO users!!!!
This expression represents the total time, Time = [tex]\frac{24}{b-3} + \frac{24}{b+3}[/tex]
What is distance?Distance is defined as the product of the speed and time.
Given,
b = the speed of the boat in miles/hour
let, effective speed upstream = (b+3)
effective speed downstream = (b-3)
∵Time = distance/ speed
Given that, upstream a distance of 24 miles
Time = [tex]\frac{24}{b-3} + \frac{24}{b+3}[/tex]

"11 less than three times a number is the same as 75 less than the product of -1 and the number"
Answer:
x=-16
Step-by-step explanation:
Let the number be x.
11 less than three times a number would be represented as 3x - 11.
75 less than the product of -1 and the number would be represented as -x - 75
Those two expressions are the same.
3x - 11 = -x - 75
3x = -x - 64
4x = -64
x = -16

∠1 and ∠2 are complementary angles. Given m∠1=83°, find m∠2.
Reasoning: Complementary angles always add to 90 degrees.
If angle 2 was x, then x+83 = 90 solves to x = 7
The measure of m∠2 is 7° due to the pair of angles being complementary.
What are complementary angles?The complementary angles are defined as when pairing of angles addition to 90° then they are called complementary angles. There are two types of supplementary angles.
Adjacent angles: Adjacent angles are the type of supplementary angles. Adjacent angles have a common side and vertex, for example, a corner point. Their points do not overlap in any way. In other terms, adjacent angles are pairs of two angles next to each other.
We have been given that the pair of angles as
m∠1 = 83° and m∠2 = x
Here, the pairing of angles sums up to 90° then they are called complementary angles.
So x + 83 = 90°
⇒ x = 90° - 83°
⇒ x = 7°
Therefore, the value of m∠2 is 7°.
