Answer:
The sample of farms required should be 550 large.
Step-by-step explanation:
Let the sample =K,
mean=np=100
Standard deviation==500
probability =Z=0.90
from the normal probability formula,
Z=
0.9=
500 X 0.9=K-100
450=K-100
K=450+100=550
Hence, the sample of farms required should be 550 large.
Answer:
Equation:
21 = 1 + m
Solution:
20 = m
Step-by-step explanation:
What we know:
- Karim drank 1 cup of milk at breakfast
- Karim drank a total of 21 cups of milk
- m = the amount of milk, in cups, Karim drank after breakfast
We know that Karim drank 21 cups of milk in a day. In an equation, that would look like this:
21 =
What does 21 equal?
The amount of milk Karim drank at breakfast plus the amount of milk Karim drank after breakfast.
21 = milk at breakfast + milk after breakfast
Let's substitute what we know into this equation:
21 = milk at breakfast + milk after breakfast
21 = 1 + m
Now that we have our equation, let's solve.
21 = 1 + m
-1 -1
20 = m
Therefore, Karim drank 20 cups of milk after breakfast.
Your answer is 2 and four ninths
2 4/9 (fraction)
You can find replcing x and y by the coordinates of the points
A : 5.-2 + 5 ≠9 not solution
B : 5.1 + 4 = 9 so 3.1 + 2.4 = 11 ≠4 not solution
C: 5.2 + = 9 so 3.2 + 2.-1 = 4 both are right then C is solution
D: 5.4 - 4 = 16 ≠ 9 not solution
Interval notation uses an ordered pair inside brackets. The ordered pair is ...
... lower end of the interval, upper end of the interval
The brackets are square if the endpoint is included (solid dot, or "≤"), and they are curved (parentheses) if the endpoint is not included (open dot, or "<"). The brackets don't have to match.
Here, your interval is -4 ≤ x ≤ -1, so we use square brackets around the end values -4 and -1.
... [-4, -1]
