3 are expected to have the condition.
The expected value is the found by multiplying the probability by the number in the sample:
(1/200)×600
= (1/200)×(600/1)
= (1×600)/(200×1)
= 600/200 = 3
Answer:
The ratio of the number of female teachers to the number of male teachers is 18:5.
Step-by-step explanation:
First: Review how to write a ratio:
To write a ratio, take the two quantities, and put them on both sides of a colon (:). So, our two quantities our 18 and 5. But, they need to be in a specific order:
There are 18 female teachers and 5 male teachers at Ashley's school. What is the ratio of the number of female teachers to the number of male teachers?
Since, they mentioned the number of female teachers first, we put the quantity of female teachers first. So we will write 18 first and 5 after. So, the ratio is 18:5.

Answer:
Each Novis share 7 sheep and each Expert share 12 sheep.
Step-by-step explanation:
Here, N represent the number of novices and E represent the number of experts needed for the company to meet its goal,
∵ All novices share the same number of sheep per day and all experts share the same number of sheep per day.
Let the sheep per day by a Novice = x and sheep per day by an expert = y,
So, the total sheep = xN + yE
According to the question,
Total sheep ≥ 700
⇒ xN + yE ≥ 700,
By here, we have given the inequality for the given scenario,
7N+12E ≥ 700
By comparing,
x = 7 and y = 12
Hence, Each Novis share 7 sheep and each Expert share 12 sheep.
