Answer: n = 5
Step-by-step explanation:
7 + n/2 = 10
Subtract 7 from 7 and 10
n/2 = 3
divide 2 from n/2 and 10
n/2 divided by 2 equals
n = 10
10/2 = 5
Answer:
Exponential
P(X) = P_0 (2)^{2x}
Step-by-step explanation:
Given that at the first count, there were 15 pairs
of male and female squirrels (30 squirrels total). After 6 months, the city workers recorded a total of 60 squirrels,
and after a year, there were 120.
i.e. every 6 months population of squirrel is doubling.
a) Function is exponential since every time of 6 months population is doubled
b) The function that represents the population of squirrels recorded over x number of years.
We know that every 1/2 year it doubles. Hence initially if P0 is started with in 1/2 year it would be 2P0 and in 1 year it would be 4P0 and so on.
In other words, the model would be
where x = no of years
From the information given, a right-tailed test using the z-distribution is appropriate.
At the null hypothesis, it is <u>tested if the class of statistics students is not significantly smarter than the general population</u>, that is, their mean IQ is of at most 100, hence:
At the alternative hypothesis, it is <u>tested if they are significantly smarter</u>, that is, their mean IQ is greater than 100, hence:
- We are testing if the mean is <u>greater than a value</u>, hence it is a right-tailed test.
- We have the <u>standard deviation for the population</u>, hence, the z-distribution is used.

Answer:
18
Step-by-step explanation:
turn 3/8 into a decimal, .375, then multiply by 48
5 + n = 17 that is what the equation would look like but if you wish to solve for the variable n then you would subtract 17 - 5 = 12, so that is the answer so tecnically I just gave you the answer to 2 questions please let me know if it helps.
