Answer:
33.3% probability that both children are girls, if we know that the family has at least one daughter named Ann.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The family has two children.
The sample space, that is, the genders of the children may be divided in the following way, in which b means boy and g means girl.
b - b
b - g
g - b
g - g
We know that they have at least one girl. So the sample space is:
b - g
g - b
g - g
What is the probability that both children are girls, if we know that the family has at least one daughter named Ann?
Desired outcomes:
Both children being girls, so
g - g
1 desired outcome
Total outcomes
b - g
g - b
g - g
3 total outcomes
Probability
1/3 = 0.333
33.3% probability that both children are girls, if we know that the family has at least one daughter named Ann.
You will need to use the compound growth formula - this is...
final number = starting number * (multiplier ^ number of years)
We can turn the 6% into a multiplier by dividing it by 100 and adding 1 on to it:
6/100 = 0.06
0.06+1 = 1.06
Then we can say that the starting number is 254 and the number of years is X, we can then place this all into the original formula:
Final population = 254 * (1.06 ^ X)
Hope this helps! :)
Subtract 87 by 63 and there is UR answer
Answer:
The change in the depth of water per minute
Step-by-step explanation:
We are given a graph that shows the depth of water in a bathtub as water drains out
Slope is the rate of change
We can see in the graph that on increasing the value x , the value of y decreases .
x axis represents the minutes
y axis represents the depth of water(inches)
So, On increasing minutes , the depth of water decreases
So, there is a change in depth of water per minute
So, Option D is correct
The change in the depth of water per minute
