Tristian has 35 rock songs, 50 dance songs and 15 rap songs on his play list. If his music player randomly selects a song, what is the probability that it is a dance song?
Answer:
1/2
Step-by-step explanation:
35+50+15 = 100
probability of the dance song = 50/100 = 1/2
Answer:50%
Step-by-step explanation:
35+15+50=100
50 divided by 100 is 0.5 or you can do it as a fraction and get 50/100

Answer:
P(for) = 5/8
P(against) = 3/10
P(undecided)= 3/40
Step-by-step explanation: Again, find the total number of people Devi surveyed.
40 people got surveyed in total. So P(for) means to find how many people wanted to vote for the mayor. In the table, it says 25 voted for the current mayor. So 25/40. Then we can simplify it to 5/8.
Then find how many people voted against her. 12 people voted against her. 12/40 is 3/10.
Finally, find how many people were indecisive. 3 people were indecisive. 3/40. We cannot simplify it, so leave it like that. Hope this helps.

What is the area of a sector bounded by an 80° arc? (use 3.14 for 1)
16.75 ft
Answer:
Area of sector bounded by angle = 100.37 ft² (Approx.)
Step-by-step explanation:
Given:
Radius of a circle = 12 feet
Arc angle θ = 80°
Find:
Area of sector bounded by angle
Computation:
Area of sector bounded by angle = [θ/360][πr²]
Area of sector bounded by angle = [80/360][(3.14)(12)²]
Area of sector bounded by angle =[0.22][(3.14)(144)]
Area of sector bounded by angle = [0.22][452.16]
Area of sector bounded by angle = 100.37 ft² (Approx.)

Thickness measurements of ancient prehistoric Native American pot shards discovered in a Hopi village are approximately normally distributed, with a mean of 4.8 millimeters (mm) and a standard deviation of 0.7 mm. For a randomly found shard, find the following probabilities. (Round your answers to four decimal places.) (a) the thickness is less than 3.0 mm
Answer:
0.0051 = 0.51% probability that the thickness is less than 3.0 mm
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of 4.8 millimeters (mm) and a standard deviation of 0.7 mm.
This means that [tex]\mu = 4.8, \sigma = 0.7[/tex]
(a) Probability that the the thickness is less than 3.0 mm
pvalue of Z when X = 3. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{3 - 4.8}{0.7}[/tex]
[tex]Z = -2.57[/tex]
[tex]Z = -2.57[/tex] has a pvalue of 0.0051
0.0051 = 0.51% probability that the thickness is less than 3.0 mm

Answer:

Area of a cylinder = area of circle x length
r = 8/2 = 4
[tex]4^{2}[/tex]π x 3 = 48π = 150.7964474
Answer:
37.68ft³
Step-by-step explanation:
So the formula for the volume of a cylinder is base x height our height is 3 but we have to find the area of the base:
the formula is: radius² x 3.14 (pi)
so we find the radius by dividing the diameter by 2: 8 ÷ 2 = 4
4 x 3.14 = 12.56
So the area of the base is 12.56ft²
now we plug that into our equation:
12.56 x 3 = 37.68
So the volume of the cylinder is 37.68ft³
hope this helps:)

Find the area of this parallelogram. Be sure to include the correct unit in your answer.
Answer:
66 sq.ydStep-by-step explanation:
Given,
Base of the parallelogram = 11 yd
Height of the parallelogram = 6 yd
Therefore,
Area of the parallelogram = base × height
= 11 yd × 6 yd
[tex] = 66 {yd}^{2} [/tex]
Hence,
Area of the parallelogram is 66 sq. yd

Answer:
29 day) $15.00
30 day $15.00
31 day $15.00
The cost was the same for all three days
Step-by-step explanation:
Rover = 3/4 can
Bobo = 1/2 can
29(3/4) + 29(1/2) = 21.75 + 14.5 = 36.25 cans
36.25/3 = 12.08
must buy 4 packs of 3 at $5.00 each = $15.00
30(3/4) + 30(1/2) = 22.5 + 15 = 37.5 cans
37.5/3 = 12.5
must buy 4 packs of 3 at $5.00 each = $15.00
31(3/4) + 31(1/2) = 23.25 + 15.5 = 38.75 cans
38.75/3 = 12.92
must buy 4 packs of 3 at $5.00 each = $15.00

Step-by-step explanation:
A wheelchair ramp is being built for entrance to a portable classroom. If the ramp has a slope of
1/12 and has a horizontal length of 5 m, what is its height to the nearest tenth of a metre?
a1.1 m
c. 0.4 m
b. 0.8 m
d. 0.3 m
Answer: A
Step-by-step explanation: Because you multiple 5m by 1/12?
If the ramp has a slope of [tex]\frac{1}{12}[/tex] and has a horizontal length of [tex]5m[/tex] then its height to the nearest tenth of a meter will be [tex]0.4 \ m[/tex] .
What is slope ?Numerical measure of a line's inclination relative to the horizontal. The slope of any line, ray, or line segment is the ratio of the vertical to the horizontal distance between any two points on it.
i.e. Slope [tex]m = \frac{\text{rise}}{\text{Length}}= \frac{H}{L}[/tex]
We have,
The ramp has a slope of [tex]\frac{1}{12}[/tex],
Horizontal length of [tex]5m[/tex]
Height of ramp [tex]=x[/tex]
So,
Slope [tex]=\frac{H}{L} = \frac{1}{12}[/tex]
[tex]\frac{H}{5} =\frac{1}{12}[/tex]
[tex]H=\frac{5}{12}[/tex]
[tex]H=0.4 \ m[/tex]
So, the Height of the ramp is [tex]0.4 \ m[/tex] .
Hence, we can say that if the ramp has a slope of [tex]\frac{1}{12}[/tex] and has a horizontal length of [tex]5m[/tex] then its height to the nearest tenth of a meter will be [tex]0.4 \ m[/tex] .

Answer:
4
Step-by-step explanation:
four Point perspective
Answer:
one point perspective
Step-by-step explanation:
It is one point perspective because if you are thinking about birds eye view, you have to consider that they height a bird can fly is very very high. So you have to be thinking critically, it cannot be 4 point perspective nor 3 point perspective due to the fact, that that is worm eye view. Thus, the answer it leaves you with is 1 point view and 2 point perspective. Two point perspective is us, it would be like us watching a building (which isn't that high). Hence, the last answer you are left with is one point perspective.

Answer:
C and D
Step-by-step explanation:
Extraneous solutions arise in a couple of cases, both of which are illustrated in this list of answer choices.
1. Square roots (and other even-index radicals). The square root is defined only for positive arguments. When the radical is removed by squaring the equation, the possibility of negative arguments is introduced. Hence, there may be extraneous solutions.
Example:
x = √(x +2) ⇒ x² = x+2 . . . has 2 roots, one of which is extraneous
__
2. Rational function equations. Such an equation is only defined when the denominator is not zero. A method often taught for solution of these equations is "cross-multiplying"--essentially multiplying by the product of the denominators. In the case where this product is not the least common denominator, the equation will have an extra factor that can introduce an extraneous root.
__
The answer choices C and D are likely to have extraneous roots based on the above observations.
_____
Additional comment
Choice D would usually be solved by cross-multiplying. That would give the quadratic equation (x -3)² = 0, which only has solutions x=3. The denominators are zero at x=3, so these solutions are extraneous. If the right side is subtracted from the left side, the fractions can be combined to give ...
((x+3) -6)/((x -3)(x +3)) = 0 ⇒ 1/(x+3) = 0 . . . . no solution
