Step-by-step explanation:
An experiment is pulling a ball from an urn that contains 3 blue balls and 5 red balls. a.) Find the probability of getting a red ball. b.) Find the probability of getting a blue ball. c.) Find the odds for getting a red ball. d.) Find the odds for getting a blue ball.
Answer:
Step-by-step explanation:
The urn contains 3blue balls 5 red balls
a) probability of getting a red ball
P=no of favourable of outcomes /total no outcomes
P(red ball) = 5/8
b) Probability of blue ball
P(blue ball) = 3/8
c) Odds getting a red ball
odds in favour of any object = m/n
m : event to occur
n : event will not occur
Odds(red ball) = 5/3
d)
Odds(blue) = 3/5
why does it want me to join their group? itll just stop people from getting answers. Which is the WHOLE point of this site may i tell you.
Answer:
because they want money.
Step-by-step explanation:
So I kind of get proofing but I am lost for what you call it when two sides that aren't adjacent are supplementary. Is it just supplementary angles? I want to say either <3 and <1 are congruent or <2 and <3 are congruent. If I could get help on the rest of the problem that would be much appreciated.
Let angle 4 denote the angle adjacent to angle 3 on the right side (so between lines a and b, to the right of line c). Angles 3 and 4 are then supplementary.
Lines a and b are parallel, so angles 1 and 4 are congruent because they are alternating interior angles.
By the transitive property, angles 2 and 4 are also congruent.
Again, transitively, angles 2 and 3 are supplementary.
Let angle 5 denote the angle to the left of angle 2 (between a and b, to the left of d). Angles 5 and 2 are supplementary.
Transitively, angles 5 and 3 are congruent.
These two angles correspond to one another, so lines c and d are parallel.

Which statement describes the behavior of the graph of the function shown at the vertical asymptotes?
As x approaches -7 from the left, y approaches ∞.
As x approaches -7 from the right, y approaches -∞.
As x approaches 7 from the left, y approaches –∞.
As x approaches 7 from the right, y approaches –∞.
This shows that as x approaches -7 and 7, the value of y approaches infinity. As x approaches -7 from the left, y approaches ∞.
Vertical asymptotes of a functionThe vertical asymptotes of a function is the point where the denominator of the rational function approaches zero.
Given the rational function shown:
[tex]\dfrac{-2x^2+14}{x^2-49}[/tex]
The vertical asymptotes occurs when x^2 - 49 = 0
Add 49 to both sides
x^2-49 + 49 = 49
x^2= 49
x = ±7
This shows that as x approaches -7 and 7, the value of y approaches infinity

Answer:
15/16
Step-by-step explanation:
The unit rate is pages per minute, so divide the pages by the minutes:
(5/8)/(2/3) = (5/8)·(3/2) = 15/16 pages per minute

What is the constant ratio of an exponential curve that passes through the points (0,3)
and (5,96)?
Answer:
[tex]r = 2[/tex]
Step-by-step explanation:
Given
[tex](x_1,y_1) = (0,3)[/tex]
[tex](x_2,y_2) = (5,96)[/tex]
Required
Determine the common ratio
An exponential function is of the form.
[tex]y(x) = ar^x[/tex]
For:
[tex](x_1,y_1) = (0,3)[/tex]
We have:
[tex]3 = a * r^0[/tex]
[tex]3 = a * 1[/tex]
[tex]a= 3[/tex]
For
[tex](x_2,y_2) = (5,96)[/tex]
We have:
[tex]96 = ar^5[/tex]
Substitute 3 for a
[tex]96 = 3 * r^5[/tex]
Divide both sides by 3
[tex]\frac{96}{3} = \frac{3 * r^5}{3}[/tex]
[tex]32 = r^5[/tex]
Express 32 as an exponent of 2
[tex]2^5 = r^5[/tex]
By comparison
[tex]2 = r[/tex]
[tex]r = 2[/tex]

What percent is represented by the shaded area?
Answer: 40%
Step-by-step explanation:
The shaded area represents 4/10 if you multiply the top and bottom by 10 you should get 40/100 which gives you 40% since percents are on a scale from 1 to 100.
Point P is in the interior of ∠NOQ. If m∠NOP = 37 and m∠NOQ = 123, what is m∠POQ?
Answer: mPOQ = 86°
Step-by-step explanation: I took the test yesterday and got it correct, I am reliable
The value of the angle m∠POQ will be the difference between ∠NOQ to m∠NOP thus it will be 86°.
What is an angle?An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.
As per the given,
∠NOQ = ∠NOP + ∠POQ
123 = 37 + ∠POQ
∠POQ = 123 - 37 = 86°
Hence "The value of the angle m∠POQ will be the difference between ∠NOQ to m∠NOP thus it will be 86°".

Divide 24 tonnes in the ratio 1:2.
Answer: it would be c on the test if your not on the test i dont know what it would bb ;]
Step-by-step explanation:
A ratio is a way of comparing two or more similar quantities. Ratios can be used to compare
costs, weights, sizes and other quantities.
For example, suppose we have a model boat which is 1 m long, whereas the actual boat is 25 m
long. Then the ratio of the length of the model to the length of the actual boat is 1 to 25. This
is written as
1 : 25 .
Note there are no units included, and note also the use of the colon to represent the ratio.
Ratios are also used to describe quantities of different ingredients in mixtures. Pharmacists
making up medicines, manufacturers making biscuits and builders making cement all need to make
mixtures using ingredients in the correct ratio. If they don’t there may be dire consequences!
So knowing about ratios is not only very important, but extremely useful and crucial in certain
circumstances.
For example, mortar for building a brick wall is made by using 2 parts of cement to 7 parts o

Answer:
48 cm^2
Step-by-step explanation:
We can substitute the h in the given equation with 8.
1/2 * (8+4) * 8
Next we can add inside the parenthesis
1/2* (12) * 8
Another way we can write 1/2* 12 is 12 divided by 2 which is equivalent to 6.
So, now our equation is 6*8
6*8 = 48 so our answer is 48 cm^2

−2x+5−5>49−5
−2x>44
Step 2: Divide both sides by -2.

let (-6,5) be a point on the terminal side of theta. find the exact values of sintheta, costheta, and sintheta
Given:
The point is (-6,5).
It is on the terminal side of theta.
To find:
The values of [tex]\sin\theta[/tex] and [tex]\cos \theta[/tex].
Solution:
In the point (-6,5),
x-coordinate : x=-6
y-coordinate : y=5
So, [tex]r=\sqrt{x^2+y^2}[/tex]
[tex]r=\sqrt{(-6)^2+(5)^2}[/tex]
[tex]r=\sqrt{36+25}[/tex]
[tex]r=\sqrt{61}[/tex]
Now,
[tex]\sin \theta=\dfrac{y}{r}[/tex]
[tex]\sin \theta=\dfrac{5}{\sqrt{61}}[/tex]
[tex]\cos \theta=\dfrac{x}{r}[/tex]
[tex]\cos \theta=\dfrac{-6}{\sqrt{61}}[/tex]
Therefore, the required values are [tex]\sin \theta=\dfrac{5}{\sqrt{61}}[/tex] and [tex]\cos \theta=-\dfrac{6}{\sqrt{61}}[/tex].

A light bulb factory produces 1,409 light bulbs every hour. Approximately 1.36% of the light bulbs are defective, and do not work. Using the binomial distribution, what is the standard deviation of the number of defective bulbs produced in an hour
Answer:
The value is [tex]\sigma = 4.35[/tex]
Step-by-step explanation:
From the question we are told that
The number of light bulbs produce every hour is n = 1409
The proportion of light bulbs that are defective is [tex]p = 0.0136[/tex]
Generally from the question we are told to use binomial distribution hence the standard deviation of the number of defective bulbs produced in an hour is mathematically represented as
[tex]\sigma = \sqrt{n * p * (1- p )}[/tex]
=> [tex]\sigma = \sqrt{1409 * 0.0136 * (1 - 0.0136 )}[/tex]
=> [tex]\sigma = 4.35[/tex]
