When the sample is given, the number of elk are likely to be infected is to be considered as the 1,215.
Calculation of the number of elk:Since the population is 6,750.
The random sample is 50.
So here be like
[tex]6750[/tex] ÷ [tex]50[/tex] × [tex]9[/tex]
= 1,215

What is the rate of change for a linear function containing the points 2,12 and 6,6?
Answer:
- [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
the slope m between the 2 points is a measure of the rate of change
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (2, 12 ) and (x₂, y₂ ) = (6, 6 )

1. Suppose a married man and woman both carry the gene for cystic fibrosis but don't
have the disease themselves. According to the laws of genetics, the probability that
any child they have will develop cystic fibrosis is .25.
a) Explain what this probability means.
b) If the couple has 4 children, is one of them guaranteed to have cystic fibrosis.
Answer:
a) Probability is the chance or possibility that an event will occur.
b) No,
just as the question states there is a 25% chance of this event happening in a child, so no matter the number of children they have the chances of them getting cystic fibrosis is 25% for each child and it's never guaranteed.

Step-by-step explanation:
the probability of making one shot is 75% or 0.75 or 3/4.
the probability to make 2 shots is then
3/4 × 3/4 = 9/16 = 0.5625
and so on.
the probability to miss 1 shot is then 25% or 0.25 or 1/4.
the probability to make at least 4 out of 5 shots is the sum of the probability to make all 5 shots plus the probability to make 4 shots.
or the probability to miss 0 plus the probability to miss 1 shot.
anyway, we can go with the positive approach. it seems to be the same complexity as the negative approach.
the probability to make all 5 shots is
(3/4)⁵ = 3⁵/4⁵ = 243 / 1024 = 0.237304688...
the probability to e.g make the first 4 shots and miss the 5th is
(3/4)⁴×1/4 = 3⁴/4⁵ = 81 / 1024 = 0.079101563...
how many possibilities do we have to make 4 out of 5 shots ?
there is no repetition, and the sequence inside the "picked" 4 does not matter, so we need combinations :
C(5,4) = 5! / (4! × (5-4)!) = 5
so, the probability to make exactly 4 out 5 shots is
81/1024 × 5 = 405/1024 = 0.395507813...
and the total probability to make at least 4 shots is
243/1024 + 405/1024 = 648/1024 = 81/128 = 0.6328125
to control,
this plus making exactly 3 plus exactly 2 plus exactly 1 plus none must be the probability 1 (as there is no other possible outcome).
making 3 :
(3/4)³×(1/4)² = 3³/4⁵ = 27/1024
C(5,3) = 5×2 = 10
270/1024
making 2 :
3²/4⁵ = 9/1024
C(5,2) = 5×2 = 10
90/1024
making 1 :
3/1024
C(5,1) = 5
15/1024
making 0 :
1/1024
in sum
(270+90+15+1)/1024 = 376/1024
plus the 648/1024 = 1024/1024 = 1

Answer:
Step-by-step explanation:
Are the outcomes on the two cards independent? Why?
Yes. The events can occur together. No. The probability of drawing a specific second card depends on the identity of the first card. No. The events cannot occur together. Yes. The probability of drawing a specific second card is the same regardless of the identity of the first drawn card.

180-(82+63)180-14535°Answer:
C) 35°
Step-by-step explanation:
From inspection of the given diagram, it appears that the line segment NOR is the diameter of the circle (where point O is the center).
Angles on a straight line sum to 180°
⇒ ∠NOP + ∠POQ + ∠QOR = 180°
⇒ 82° + ∠POQ + 63° = 180°
⇒ ∠POQ = 180° - 82° - 63°
⇒ ∠POQ = 35°
As an arc measure equals its corresponding central angle measure:
[tex]\sf \implies \overset{\frown}{PQ}= \angle POQ[/tex]

In a class of students, the following data table summarizes how many students have a brother or a sister. What is the probability that a student chosen randomly from the class is an only child?
Step-by-step explanation:
there were in total 24 students (asked) in the class.
3 have a brother and a sister (and I assume this means "at least one" in either category).
15 have (at least) a brother but no sister.
4 have no brother but (at least) a sister.
2 have no brothers and no sisters (they are "only children").
a probability is always
desired cases / possible cases.
so, when picking a student randomly, we have 24 possibilities.
out of these 24 there are only 2 that are an "only child".
therefore, the probability to pick an "only child" is
2/24 = 1/12 = 0.083333333...

A colony of 10,710 bacteria doubles in size every 129 minutes. What will the population b
516 minutes from now?
The population after 516 minutes is 171360 bacteria
How to determine the population after 516 minutesFrom the question, we have the following parameters that can be used in our computation:
Initial, a = 10,710 bacteria
Rate = doubles i.e. 2
Using the above as a guide, we have the following:
f(x) = a(2)^x
Where x is the time
516 minutes is 4 times 129 minutes
This means that
x = 516/129 = 4
So the population after 516 minutes can be calculated as follows:
f(4) = 10710 * (2)^4
Evaluate
f(4) = 171360
Hence, the population is 171360

Where does that 682 come from? It cannot be the surface area of a cube with a side of 50 inches.
The edge length is 50 inches, so s = 50
SA = 6 * 50^2
