what is function ?
In mathematics, a function is a relation between two sets, called the domain and the range, that assigns to each element of the domain exactly one element of the range.
In the given question,
To find g°f, we need to first apply the function f to -3, and then apply the function g to the result.
Step 1: Apply f to -3
f(x) = 3x + 7
f(-3) = 3(-3) + 7 = -2
Step 2: Apply g to the result of f(-3)
g(x) = 2x - 5
g(-2) = 2(-2) - 5 = -9
Therefore, g°f = -9.
So, the correct answer is (B) -9.

Find the lenghts of the sides of the rectangle ABCD shown on the coordinate plane. Suppose you double the length of each side. What would be the new coordinates of point C if the coordinate of point A stay the same
Looking at the diagram,
each small box represents one unit
The number of units from A to B is 4 units
The number of units from B to C is 3 units
Thus, the length of rectangle ABCD is 4 units and its width is 3 units.
The original coordinates are

Which type of fax funds military defense
The correct option is A which is federal tax.
The type of tax that funds military defence in the United States is the federal income tax. This is a tax levied by the federal government on individuals, businesses, and other entities based on their income. A portion of this tax revenue is allocated towards funding the military, including salaries for personnel, equipment, and operations.
It's important to note that not all of the federal income tax revenue is earmarked for military defence. The federal government uses this revenue to fund a variety of programs and services, including healthcare, education, infrastructure, and more. The allocation of funds towards military defence is determined by Congress and can vary from year to year based on national security needs.
Other taxes, such as state income tax, local income tax, and FICA tax (which funds Social Security and Medicare), do not directly fund military defence. However, all taxpayers contribute to the national defence in some way, as the federal government relies on a variety of revenue sources to fund its operations and programs, including military defence.

The population is the number of children in gymnastic class = 5.
A parameter is the mean number of steps taken by the 5 children.

Four parameters, referred to as hybrid or h Parameters, can be used to assess any linear circuit with input and output terminals. These parameters are one measured in ohm, one in mho, and two dimensionless. Hybrid is short for "mixed." These parameters are referred to as hybrid parameters since they have dual dimensions

Given that,
Suppose that there are 5 children in a gymnastics class.
One day, they count the number of steps each person takes while walking on their hands until they lose balance and come down.
The mean number of steps these children took while walking on their hands is 20 steps.
We have to find the population and parameters.
The area of interest is a particular gymnastic class, therefore all individuals or children belonging to this particular gymnastic class make up the population.
Population = number of children in gymnastic class = 5.
Parameter = mean number of steps taken by the 5 children.
Hence, Population is the number of children in gymnastic class = 5.

Select the correct answer. Which logarithmic equation is equivalent to this exponential equation? 2400=7500(10)^-x
The logarithmic equation is equivalent to this exponential equation is x = log (8/25) (option c).
In this case, we are asked to find the logarithmic equation that is equivalent to the given exponential equation:
2,400 = 7,500(10)⁻ˣ
To solve for x, we need to isolate it on one side of the equation. We can start by dividing both sides by 7,500:
2,400/7,500 = (10)⁻ˣ
The choice of base for the logarithm doesn't matter, as long as we use the same base for both sides. Let's use base 10:
log(2,400/7,500) = log(10⁻ˣ)
Using the properties of logarithms, we can simplify the right-hand side:
log(2,400/7,500) = -x*log(10)
We know that log(10) = 1, so we can simplify further:
log(2,400/7,500) = -x
x = log(8/25) = log(8) - log(25) = 0.9031 - 1.3979 = -0.4948
So the only answer choice that gives us the same equation as the original exponential equation is (C) x = log (8/25).

What is meant by growth rate?Using the current number as a starting point, subtract the prior value to determine the growth rate. To calculate the growth rate in percentage terms, divide the difference by the previous amount and multiply the result by 100. Growth Rate equals (Ending Value - Beginning Value) - 1. The year-over-year (YoY) growth rate of a business, for instance, would be 20% if its revenue increased from $100 million in 2020 to $120 million in 2021.
GDP, turnover, wages, etc., all have growth rates that reflect how much they have changed over time (month, quarter, year). Percentages are a pretty common way to communicate it.

Give a reason for your answer.
a) She can make 400 milliliters of the fizzy drink.
b) The change does not affect the greatest amount of drink.
If kerry is correct what is the greatest amount of fizzy drink she can make?We know that the fizzy drink is 7 parts apple juice and 3 parts lemonade. And Kerry thinks that she has 280ml of apple juice and 180 ml lemonade.
If we divide the total amount of apple juice in 7 parts, then each part has:
280ml/7 = 40ml
Then we need 3 parts of 40ml of the lemonade, this is:
3*40ml = 120ml
Then the total amounf of drink fizz that she can make is:
280ml + 120ml = 400ml.

Given a standardized normal distribution (with a mean of O and a standard deviation of 1), determine the following probabilities.
a. P(Z > 1.09) b. P(Z < -0.22) c. P(-1.96
d. What is the value of Z if only 8.08% of all possible Z-values are larger?
Answer:
a) P(Z > 1.09) = 0.1379
b) P(Z < -0.22) = 0.4129.
c) P(Z < -1.96) = 0.025, P(Z > -1.96) = 0.025
d) Z = 1.4
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:
\(Z = \frac{X - \mu}{\sigma}\)
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
a. P(Z > 1.09)
This is 1 subtracted by the pvalue of Z = 1.09.
Z = 1.09 has a pvalue of 0.8621
1 - 0.8621 = 0.1379, so
P(Z > 1.09) = 0.1379
b. P(Z < -0.22)
This is the pvalue of Z = -0.22.
Z = -0.22 has a pvalue of 0.4129. So
P(Z < -0.22) = 0.4129.
c) P(Z < -1.96) or P(Z > -1.96)
Z = -1.96 has a pvalue of 0.025. So
1 - 0.025 = 0.975
P(Z < -1.96) = 0.025
P(Z > -1.96) = 0.025
d. What is the value of Z if only 8.08% of all possible Z-values are larger?
Z with a pvalue of 100 - 8.08 = 91.92 = 0.9192, so Z = 1.4
