Step-by-step explanation:
Probabilities are used to determine the chances of events.
The probability that at least 2 animals are infected is (c) 0.913
The proportion of the animal infected is given as:
[tex]p =60\%[/tex]
The probability is then calculated using the following binomial equation
[tex]P(x) = ^nC_xp^x(1-p)^{n-x}[/tex]
In this case,
[tex]n = 2[/tex]
To calculate the probability that at least 2 animals are infected, we start by calculating the probability that not up to 2 animals are infected.
So, we have:
[tex]P(x<2) =P(0) + P(1)[/tex]
This gives
[tex]P(x<2) = ^5C_0 \times (60\%)^0 \times (1-60\%)^{5-0}+ ^5C_1 \times (60\%)^1 \times (1-60\%)^{5-1}[/tex]
Simplify
[tex]P(x<2) = 1 \times (60\%)^0 \times (40\%)^{5}+ 5 \times (60\%) \times (40\%)^{4}[/tex]
[tex]P(x<2) = 0.08704[/tex]
Using the complement rule, we have:
[tex]P(x \ge 2) = 1 - P(x<2)[/tex]
So, we have:
[tex]P(x \ge 2) = 1 - 0.08704[/tex]
[tex]P(x \ge 2) = 0.91296[/tex]
Approximate
[tex]P(x \ge 2) = 0.913[/tex]
Hence, the probability is (c) 0.913

Been stuck on this all day!! Helppp
Answer:
Step-by-step explanation:
You have to use the arithmetic sequence
f(n)=f(n-1)+d
You can plug in (40,10) and (50,20)
(10)=f(1)+39d
(20)=f(1)+19d
subtract
-10=20d divide
d=-1/2
plug into one of the equations above
(10)=f(1)+39(-1/2)
10=f(1)-39/2
59/2=f(1)
f(1)=29.5
plug into formula
f(n)=29.5-1/2(n-1)
f(n)= -1/2n +30 final equation (Plug in the table values into "n") to solve

Answer:
D
Step-by-step explanation:
EDGE 2021
The limit of the given functions f(x)=85 and lim f(x)=120.
If any of the following conditions are met, a function is said to be discontinuous:
The function at x = a has left- and right-hand bounds, but they are not equal.The function at x = a has a left-hand limit and a right-hand limit that exist, are equal, but are not equal to f(a).We have given that,
Function f(x) has a jump discontinuity at x = 8.
We have to determine a statement that identifies possible one-sided limits at x = 8.
Then, lim f(x)=85 and lim f(x)=120

Kyle bought some boxes of donuts. There were 4 donuts in each box, and Kyle bought 76 donuts in all. Write an equation, that when solved, will tell how many boxes, b, of donuts Kyle bought?
Answer:
b=76/4
Step-by-step explanation:
Since there are 4 donuts in each box, and 76 boxes total, then you know that you need to divide the number of donuts by the amount of donuts in each box. b= 19 if u needed that. Cheers
Answer:
The answer is 19 boxes
Step-by-step explanation:
Since there were 4 donuts in each box all you have to do is divide 76 by 4 since there is 76 donuts in all 76 ÷ 4 = 19 boxes (79 equally distributed into 19 boxes)

Evaluate the expression 2y + 10 + y2 of y=8
The evaluation of the expression 2y + 10 + y² at y = 8 returns 90 as its value.
How to evaluate a given mathematical expression with variables if values of the variables are known?You can simply replace those variables with the value you know of them and then operate on those values to get a final value. This is the result of that expression at those values of the considered variables.
The considered expression is 2y + 10 + y²
We need to evaluate it at y = 8
Putting 8 in place of y in the expression, we get:
[tex]2y + 10 + y^2|_{y=8} = 2 \times 8 + 10 + (8)^2 = 16 + 10 + 64 = 90[/tex]
Note that small subscript of y = 8 shows that we're evaluating the expression for y = 8.
Also, when symbols are used with multiplication, we usually hide the multiplication sign and just keep the multiplying quantities close to each other, this is why [tex]2 \times y[/tex] was written 2y in the expression.
Thus, the evaluation of the expression 2y + 10 + y² at y = 8 returns 90 as its value.

how do i transform this equation 5(3x+9)-2x=15x-2(x-5)
You have to multiply to get a simple equation so it would be 15x+45=15x-2x+10 and that’s where my knowledge stops with that
<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3
Let's solve your equation step-by-step.
5 ( 3x + 9 ) − 2x = 15x − 2 ( x − 5 )
Step 1: Simplify both sides of the equation.
5 ( 3x + 9 ) − 2x = 15x − 2 ( x − 5 )
( 5 ) ( 3x ) + ( 5 ) ( 9 ) + −2x = 15x + ( −2 ) ( x ) + ( −2 ) ( −5 ) ( Distribute )
15x + 45 + −2x = 15x + −2x + 10
( 15x + −2x ) + ( 45 ) = ( 15x + −2x ) + ( 10 ) ( Combine Like Terms )
13x + 45 = 13x + 10
13x + 45 = 13x + 10
Step 2: Subtract 13x from both sides.
13x + 45 − 1 3x = 13x + 10 − 13x
45 = 10
Step 3: Subtract 45 from both sides.
45 − 45 = 10 − 45
0 = −35

A bird is at the top of a tree 8 meters tall. You are on the ground, 10 meters away from the bird. How far are you
from the base of the tree?
Answer: 6 meters
Step-by-step explanation:
I had this question and got the answer right.
The distance from the base of the tree will be 6 meters.
What is a Pythagorean theorem?The Pythagorean theorem says that the sum of the square of the perpendicular and the base will be equal to the square of the hypotenuse of the right-angle triangle.
Given that a bird is perched eight meters up in a tree. The bird is 10 meters away from you where you are standing.
From the Pythagorean theorem, the base will be calculated as:-
H² = P² + B²
B = √ ( H² - P² )
B = √ ( 10² - 8² )
B = √36
B = 6 meters
Hence, the 6 meters will separate you from the tree's base.

I will increase your salary from $12,000 to $15,000. What is the percentage increase
Answer:
i think 20%
Step-by-step explanation:
The percent increase of the salary is 25%.
We have,
the salary increases from $12,000 to $15,000
So, Change in Amount= (15,000 - 12,000)
= 3, 000
Now, Percent increase = change in amount/ original amount x 100
= 3000/ 12000 x 100
= 1/4 x 100
= 100/4
= 25%
Thus, the percent increase is 25%.

All other things being equal, by how much will nominal GDP expand if the central bank increases the money supply by $100 billion, and the velocity of money is 3?
If the central bank increases the money supply by $100 billion and the velocity of money by 3, then the nominal GDP will increase by $300 billion.
Mark brainlist plz
The value of nominal GDP, when the central bank increases the money supply by $100 billion, and the velocity of money is 3, is 300.
What is the equation of exchange?
The equation of exchange can be given as,
[tex]M\times V=P\times Q[/tex]
Here, (M) is the money supplied, (V) is the velocity of the money, (P) is level of price and (Q) is Real GDP.
The central bank increases the money supply by $100 billion, and the velocity of money is 3. Here, we have,
[tex]M=300\\V=3[/tex]
The product of level of price and Real GDP is nominal GDP.
[tex]M\times V=P\times Q\\100\times 3=\text{Nominal GDP}\\\text{Nominal GDP}=300[/tex]

You can either use the x value to find out the proper y value
or
You can use the y value to find out the proper x value
Proper y value
Let x = 2
y = 7*2

So the proper y value given that x = 2 is 14.
Proper x value
Let y = 21
