Help me I don’t know what this means
Answer:
46 is the 15th term.
Step-by-step explanation:
In this question they have given us the function 3x + 1 to determine the 15th term in the table. X = the input or the numbers in that column. Now we must substitute x in our function to figure out the output.
Example:
3(1) + 1 = 4
So for the output for 1 the answer would be 4. You must follow this rule for 0 and 2 as well.
For 15 we must substitute 15 for x.
3(15) + 1 = 46
So 46 would be the 15th term.
Answer:
46
Step-by-step explanation:
[tex]3x+1[/tex]
To determine the 15th term using this expression, plug in 15 as x
[tex]= 3(15)+1\\= 45+1\\= 46[/tex]
Therefore, the 15th term is 46.
I hope this helps!

For the following exercise, use the compound interest formula, A(t) = P(1 +r/n)^t.
where money is measured in dollars.
After a certain number of years, the value of an investment account is represented by the expression 10,400(1 +0.02/2)^20
had the account been accumulating interest?
How many years
Answer:
A = $10,441.68
A = P + I where
P (principal) = $10,400.00
I (interest) = $41.68
Step-by-step explanation:
First, convert R as a percent to r as a decimal
r = R/100
r = 0.02/100
r = 0.0002 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 10,400.00(1 + 0.0002/2)(2)(20)
A = 10,400.00(1 + 0.0001)(40)
A = $10,441.68
Summary:
The total amount accrued, principal plus interest, with compound interest on a principal of $10,400.00 at a rate of 0.02% per year compounded 2 times per year over 20 years is $10,441.68.
The total amount , with compound interest on a principal of $10,400.00 at a rate of 0.02% per year compounded 2 times per year over 20 years is $10,441.68.
What is Compound interest?Compound interest is a method of calculating the interest charge. In other words, it is the addition of interest on interest.
Compound Interest =[tex]P(1+r/n)^rt[/tex]
Given that
A = $10,441.68
A = P + I
P (principal) = $10,400.00
I (interest) = $41.68
First, we need to convert R as a percent to r as a decimal
r = R/100
r = 0.02/100
r = 0.0002 rate per year,
Then we will solve the equation for A
A = [tex]P(1+r/n)^rt[/tex]
[tex]A = 10,400.00(1 + 0.0002/2)^{(2)(20)}[/tex]
A = 10,400.00(1 + 0.0001)
A = $10,441.68
Hence, The total amount , with compound interest on a principal of $10,400.00 at a rate of 0.02% per year compounded 2 times per year over 20 years is $10,441.68.

The diagram shows the spot on a basketball court called the "key". what is the area of the key? Use 3.14 for pi
Assume your home is assessed at $245,000. You have a $171,000 loan for 25 years at 6 percent. Your property tax rate is 1.4 percent of the assessed value. In year one, you would pay $10,260 in mortgage interest and $3,430 in property tax (1.4 percent on $245,000 assessed value).
Answer: $3,833.20
Step-by-step explanation:
Mortgages interest and property tax are both federal deductions so they will reduce taxes:
= 10,260 + 3,430
= $13,690
The tax saving is therefore:
= 13,690 * tax rate
= 13,690 * 28%
= $3,833.20

The number of eggs that a female house fly lays during her lifetime is normally distributed with mean 790 and standard deviation 92.
Random samples of size 98 are drawn from this population, and the mean of each sample is determined. What is the probability that
the mean number of eggs laid would differ from 790 by less than 30? Round your answer to four decimal places.
Answer:
0.9988 = 99.88% probability that the mean number of eggs laid would differ from 790 by less than 30.
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
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.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Mean 790 and standard deviation 92.
This means that [tex]\mu = 790, \sigma = 92[/tex]
Samples of 98
This means that [tex]n = 98, s = \frac{92}{\sqrt{98}}[/tex]
What is the probability that the mean number of eggs laid would differ from 790 by less than 30?
This is the pvalue of Z when X = 790 + 30 = 820 subtracted by the pvalue of Z when X = 790 - 30 = 760. So
X = 820
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{820 - 790}{\frac{92}{\sqrt{98}}}[/tex]
[tex]Z = 3.23[/tex]
[tex]Z = 3.23[/tex] has a pvalue of 0.9994
X = 760
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{760 - 790}{\frac{92}{\sqrt{98}}}[/tex]
[tex]Z = -3.23[/tex]
[tex]Z = -3.23[/tex] has a pvalue of 0.0006
0.9994 - 0.0006 = 0.9988
0.9988 = 99.88% probability that the mean number of eggs laid would differ from 790 by less than 30.

I am really confused what a mean is in math
Answer:
A mean in math is when you have a set of numbers, you add up all numbers of the set and then divide that sum by the total amount of numbers.
Example: 3,6,8,9
3+6+8+9=26
26/4 (because there is four numbers)
26/4= 6.5
So the mean of that set will be 6.5

As you landscape a 4 leaf clover intersection, you will need to buy
enough grass seed to cover all 4 circles. Each of the circles has the same
diameter: 47 meters. Calculate the total area of all grass seed needed to
cover all 4 circles.
Answer:
A = 6940 m²
Step-by-step explanation:
We are told that there is a clover leaf intersection.
I have attached a picture of it with the 4 circles showing.
We are told the diameter of each circle is the same and equal to 47 m.
Thus, radius = 47/2 = 23.5 m
We want to find the area of grass that will cover the 4 circles. Thus;
Formula for area of a circle is;
A = πr²
For the 4 circles, we have;
A = 4πr² = 4 × π × 23.5²
A = 6939.78 m²
Approximately A = 6940 m²
