Answer:
the required probability of is 0.1886
the approximate probability is 0.2052
Step-by-step explanation:
The farmer estimates that there's a a 9 9% chance of a cow grazing on some of the flavorful weeds
i.e P = 9.9% = 0.099
Let assume that X is a description of how the cows are grazing on some of the flavorful weeds.
The probability density function of the binomial distribution is :
a)
To calculate that the probability that none of the 16 animals in this herd ate the tasty weeds.
=
= 0.1886
Thus; the required probability of is 0.1886
b) To calculate the probability that no animal ate the weed.
By using Poisson approximation model:
=
Hence; the approximate probability is 0.2052
Answer:
D. 25
Step-by-step explanation:
f(x) = 6 – 5x and g(x) = 4x – 1
We want to subtract.
f(x) -g(x)= 6 – 5x -( 4x – 1)
Distribute the minus sign
6 – 5x - 4x + 1
I line them up vertically
– 5x +6
- 4x + 1
-------------------
-9x +7
Now let x = -2
-9(-2) +7
18+7

The equation to show the sum of two number is 160: x + y = 160.
An equation is a mathematical statement that shows that two expressions are equal.
To find two numbers that add up to 160, we can Set up an equation with two unknowns, x and y, representing the two numbers:
x + y = 160
Since there are infinitely many possible combinations of two numbers that add up to 160.
Some combinations are:
1. x = 80, y = 80
80 + 80 = 160
2. x = 50, y = 110
50 + 110 = 160
3. x = 30, y = 130
30 + 130 = 160
4. x = -20, y = 180
-20 + 180 = 160
5. x = 0, y = 160
0 + 160 = 160
These are just a few examples, and there are many other combinations of numbers that satisfy the equation x + y = 160.
