Evan, James, and Burt are fishing in a lake that has 200 fish. They are going to be fishing for three hours. What is the probability that they each will catch 3 fish?
Answer:
The probability that they each will catch 3 fish is 0.000063956
Step-by-step explanation:
The hyper geometric distribution is used to solve this as it has a population, a sample , number of successes for both the population and sample.
Here
Population size= N =200
Sample size= n =9= (3*3)
Number of successes in population = k = 3 hours
Number of successes in sample = x= 3
Applying the hyper geometric distribution
P (x=3) = kCx *(N-k) C (n-x)/ N Cn
= 3 C 3 * 197 C 6/ 200 C 9
=0.000063956
The probability that they each will catch 3 fish is 0.000063956

Does the graph of the straight line with slope of -3 and y-intercept of -4 pass through the point (-2, 2)?
Answer:
abcdefghijklmnopqrstuvwxyz
Answer:
yes
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 3 and c = - 4 , then
y = - 3x - 4 ← is the equation of the line
To determine if (- 2, 2) lies on the line, substitute x = - 2 into the equation and if y equals 2 then the point lies on the line.
y = - 3(- 2) - 4 = 6 - 4 = 2 ← true
Then the line passes through (- 2, 2 )

Answer:
is 34
Step-by-step explanation:
^<- this is the square sing
f(1)+f(-2) for f(x)=4x^2+7
f(1)=4(1)^2+7
=4+7
f(1) =11
f(-2)=4(-2)^2+7
if you square -2 there will not be no -
-2 the whole square is 4
=4(4)+7
f(-2)=23
f(1)+f(-2)=11+23=34
:. The answer is 34
Find the value of x and y from the equation
Answer:
x = 5 and y = 3
Step-by-step explanation:
5x - 3y = 16
3x - y = 12 multiply second equation by (-3)
(-3)*(3x-y) = 12*(-3) (remember we need to multiply both sides of the equation)
-9x + 3y = -36 now subtract this from the first equation
5x - 3y -9x + 3y = 16 - 36 (-3y will eliminate +3y)
-4x = -20 and 4x = 20 divide both sides by 4
x = 5 if 3x - y = 12 then 3*5 - y = 12
15 - y = 12
-y = -3 and y = 3
A box contains 6 red index cards, 3 yellow index
cards, and 4 green index cards. If Gabriella pulls out
2 cards at random from this box, without replace-
ment, what is the probability that both cards are
not green?
Answer:
11/15 = 73%
Step-by-step explanation:
because in total there are 15 cards and 4 of them is not green. You would want to see what is the probability of other colored carded after leaving out the green ones.
The probability that both cards drawn from the box are not green is 27/52.
To determine the probability that both cards drawn from the box are not green, we need to calculate the probability of each individual draw and multiply them together.
Initially, the box contains a total of 6 red index cards, 3 yellow index cards, and 4 green index cards.
For the first draw, there are a total of 13 cards in the box. Since we are interested in the probability of not drawing a green card, there are 13 - 4 = 9 non-green cards. Therefore, the probability of not drawing a green card on the first draw is 9/13.
For the second draw, there will be 12 cards left in the box. Since one green card has already been removed, there are now 12 - 3 = 9 non-green cards remaining. Thus, the probability of not drawing a green card on the second draw is 9/12.
To find the overall probability, we multiply the probabilities of each individual draw:
(9/13) * (9/12) = 27/52

Answer: 312 balcony seats and 396 ground seats
Step-by-step explanation:
Multiplying the second equation by 10, we get 10b+10g=7080.
Subtracting this from the first equation, we get that 5b = 1560, and thus b=312.
Thus, g=396.

A new car sells for $25,000. The value of the car decreases by 15% each year. What is the approximate value of the car 5 years after it is purchased? 25,000 (1 minus 0.15) Superscript 5, or approximately $11,093 25,000 minus 1500 (5), or approximately $17,500 25,000 (0.15) Superscript 5, or approximately $18,984 25,000 minus left-bracket (100 minus 15) (5) Right-bracket, or approximately $24,575
Answer:
A. 25,000 (1 minus 0.15) Superscript 5, or approximately $11,093
Step-by-step explanation:
A. 25,000 (1 minus 0.15) Superscript 5, or approximately $11,093
B. 25,000 minus 1500 (5), or approximately $17,500
C. 25,000 (0.15) Superscript 5, or approximately $18,984
D. 25,000 minus left-bracket (100 minus 15) (5) Right-bracket, or approximately $24,575
Value of the car = $25,000
Percentage decrease per year = 15%
Value after 5 years
Total percentage value of the car = 100%
Percentage value remaining each year = (100% - 15%)
= (1 - 0.15)
Decrease of the car in the next 5 years = $25,000(1 - 0.15)^5
= $25,000(0.85)^5
= $25,000(0.4437053125)
= $11,092.6328125
Approximately = $11.093
Value of the car in the next 5 years = $25,000 - $11,093
= $13,907
Answer:
It's A, $11,093
