Answers
By the inequality for x over on the right side if x is equal to or greater than 2 you use the bottom equation.
G(2) means x is 2.
Using the bottom equation replace the x’s with 2 and solve.

In the last several weeks, 18 days saw rain and 29 days saw high winds. in the same time period 7 days saw both rain and high winds. How many days saw either rain or high winds
Answers
Answer:
40 days saw either rain or high winds
Step-by-step explanation:
We solve this question using Venn sets.
I am going to say that:
Set A: Rain
Set B: High winds.
18 days saw rain
This means that [tex]A = 18[/tex]
29 days saw high winds
This means that [tex]B = 29[/tex]
7 days saw both rain and high winds.
This means that [tex]A \cap B = 7[/tex]
How many days saw either rain or high winds?
This is
[tex]A \cup B = A + B - A \cap B[/tex]
Sp
[tex]A \cup B = 18 + 29 - 7 = 40[/tex]
40 days saw either rain or high winds

Karla invests $10,000 into an account with a 2.2% interest that is compounded annually.
How much money will she have in this account if she keeps it for 5 years?

What is Future value?Future value (FV) is a financial concept that provides a monetary worth to an asset depending on future variables such as interest rates or cashflows. An investor may find it valuable to know how much their investment will be worth in five years given a projected rate of return. Future value is calculated by taking the investment value now, applying predicted growth, and estimating what the investment will be in the future.
We have,
P = $10,000
R= 2.2%
T= 5 years
So, Amount after 5 years
= P (1 + r/2[tex])^{2t[/tex]
= 10,000 (1 + 0.011[tex])^{0.022(5)}\\[/tex]
= $11, 162.78

To the nearest 1000, there are 18,000 people at a festival . Write down the minimum possible number of people at the festival
Answers
Answer:
17500
Step-by-step explanation:
17499 rounds down
17500 rounds up
The number of people is an illustration of approximation and estimation
The minimum possible number of people at the festival is 17500
The approximated number of people is:
People = 18000
Because 18000 represents people, it means that the population is a whole number
The smallest whole number that can be approximated to 18000 is 17500
i.e.
People = 17500
Hence, the minimum possible number of people at the festival is 17500

A lab is testing the amount of a certain active chemical compound in a particular drug that has been recently developed. The manufacturer claims that the average amount of the chemical is 95 mg. It is known that the standard deviation in the amount of the chemical is 5 mg. A random sample of 25 batches of the new drug is tested and found to have a sample mean concentration of 89.9 mg of the active chemical.
Calculate the 95% confidence interval for the mean amount of the active chemical in the drug. Give your answers to 2 decimal places. (suppose to be number less than and equal to mean less than and equal to another number)
Answers
Answer:
The 95% confidence interval is "87.94, 91.86".
Step-by-step explanation:
The given values are:
Sample batches,
n = 25
Sample mean concentration,
[tex]\bar{x}[/tex] = 89.9 mg
Amount of chemical,
σ = 5
α = 0.05
The critical value from Z table will be:
= [tex]Z(\frac{\alpha}{2} )[/tex]
= [tex]Z(\frac{0.05}{2} )[/tex]
= [tex]1.96[/tex]
Now,
The confidence interval will be:
= [tex]\bar{x} \pm Z(\frac{\alpha}{2} )\times \frac{\sigma}{\sqrt{n} }[/tex]
On substituting the values, we get
= [tex]89.9 \pm Z(\frac{0.05}{2})\times \frac{5}{\sqrt{25}}[/tex]
= [tex]89.9 \pm Z(\frac{0.05}{2})\times \frac{5}{5}[/tex]
= [tex]89.9 \pm1.96\times 1[/tex]
Lower limit will be:
= [tex]89.9 -1.96\times 1[/tex]
= [tex]87.94[/tex]
Upper limit will be:
= [tex]89.9 +1.96\times 1[/tex]
= [tex]91.86[/tex]
Domain and range of graph need ASAP
Answers
Answer:
Domain: [tex]-6 \leq x \leq 3[/tex]
Range: [tex]-3 \leq x \leq 6[/tex]
Step-by-step explanation:
The domain is the set of real values which can be inputted into a function and produce a real output. In this case, the domain is the following: [tex]-6 \leq x \leq 3[/tex], because this is the set of real values for which the function will produce a real output.
The range is the set of real values which a function outputs when a value from the domain is entered into the function. This is the set of y-values that one can see on the graph, the possible y-values are in between (-3) and (6).
