Answer:
FV= 5,557.23
Step-by-step explanation:
Giving the following information:
Present value= 3,400
Growth rate (g)= 1.5% every 3 minutes
Number of periods (n)= (1.65*60) / 3= 33
To calculate the future value, we need to use the following formula:
FV= PV*(1+g)^n
FV= 3,400*(1.015^33)
FV= 5,557.23

1a + 3s = $11.50
3a + 2s = $17.00
$4+$2.50(3)=$11.50
$12+$2.50(2)=$17.00
or

The value of [x] will be equivalent to x = 3.5.
What is logarithmic function? What is equation modelling? What is a mathematical equation and expression?In mathematics, the logarithm is the inverse function to exponentiation. That means the logarithm of a number [x] to the base [b] is the exponent to which [b] must be raised, to produce [x]. We can write -[tex]y=log_{e} (x)[/tex]
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given is the logarithmic equation as
2log(4x) − log(49) = 2
2log(4x) = 2 + log(49)
2{log(4) + log(x)} = 2 + log(49)
{log(4) + log(x)} = {2 + log(49)}/2
log(4) + log(x) = 1 + log(49)/2
log(4) + log(x) = 1.85
log(x) = 1.85 - log(4)
log(x) = 1.25
x = e^(1.25)
x = 3.5 {approx.}
Therefore, the value of [x] will be equivalent to x = 3.5.

The larger of two numbers is 17 more than twice the smaller. When the larger number is divided by the smaller, the quotient is 3 and the remainder is 6. Find the two numbers
Answer:
The numbers described here are 39 and 11.
Step-by-step explanation:
Let's call the numbers a and b, a being the larger. We're told two things:
The larger of the two numbers is 17 more than twice the smaller.
Which we can express as:
a = 2b + 17
When the larger number is divided by the smaller, the quotient is 3 and the remainder is 6
And that can be expressed as:
a = 3b + 6
We can now take those two expressions and, noting that they both define a, we can say that they are equivalent, and solve for b:
2b + 17 = 3b + 6
3b - 2b = 17 - 6
b = 11
With b found, we can now take either of the first expressions, and solve for a:
a = 2b + 17
a = 2(11) + 17
a = 22 + 17
a = 39
Now we can check whether that is correct by plugging it into the other expression and seeing if b still comes to 11:
a = 3b + 6
39 = 3b + 6
3b = 33
b = 11
So we know that the answer is correct.

Matt and Bree are saving for a new car. At the end of 2013, their total savings was $12,500 . In 2014, total savings increased to $15,550 . How much did Matt and Bree save in 2014
Answer:
They saved $3000 in 2014
Step-by-step explanation:
Given
[tex]Savings (2013) = \$12500[/tex]
[tex]Total (2014) = \$15500[/tex]
Required
Determine the savings in 2014
This is calculated by subtracting the savings in 2013 from the total savings.
i.e.
[tex]Savings(2014) = Total(2014) - Savings(2013)[/tex]
This gives:
[tex]Savings(2014) = \$15500 - \$12500[/tex]
[tex]Savings(2014) = \$3000[/tex]
Hence, they saved $3000 in 2014
11B. Long Beach Towing Company charges $40 plus $5 per mile to
tow a car. The Five-Star Towing Company charges $70 plus $2 per
mile. After how many miles the charges for the two companied will
be the same?
Answer:
The charges will be the same after 10 miles.
Step-by-step explanation:
Long Beach Towing Company:
Charges $40 plus $5 per mile. So after x miles, the charge will be of:
[tex]L(x) = 40 + 5x[/tex]
Five-Star Towing Company:
Chargers of $70 plus $2 per mile. So after x miles, the charge will be of:
[tex]F(x) = 70 + 2x[/tex]
After how many miles the charges for the two companied will be the same?
This is x for which:
[tex]L(x) = F(x)[/tex]
So
[tex]40 + 5x = 70 + 2x[/tex]
[tex]5x - 2x = 70 - 40[/tex]
[tex]3x = 30[/tex]
[tex]x = \frac{30}{3}[/tex]
[tex]x = 10[/tex]
The charges will be the same after 10 miles.
A manufacturing company uses two different machines, A and B, each of which produces a certain item part. The number of defective parts produced by each machine is about 1 percent. Suppose two independent random samples, each of size 100, are selected, where one is a sample of parts produced by machine A and the other is a sample of parts produced by machine B. Which of the following is true about the sampling distribution of the difference in the sample proportions of defective parts?
A The mean is 0 and the distribution is approximately normal
B The mean is 0 and the distribution will not be approximately normal
C The mean is 0.01 and the distribution is approximately normal
D The mean is 0.01 and the distribution will not be approximately normal.
Ε The mean is 1 and the distribution is approximately normal.
Answer:
B: The mean is 0 and the distribution will not be approximately normal
Step-by-step explanation:
It is true that the mean is 0 because it is the difference in the population proportions, 0.01−0.01. However, normality cannot be assumed because the sample sizes are not large enough.
The sample distribution is defined as the probability distribution of a given sample based on statistics.
The correct option is (a).
Given:
The defective parts produced by each machine is 1%.
The sample Size is 100.
Calculate the proportion of the defective parts.
[tex]\dfrac{1}{100}=0.01[/tex]
Thus, the mean of each machine is 0.01.
Now, the mean difference between both machine is 0 and proportion will be normally distributed.

write an equation that describes the function
Answer:
y= –x + 1
Step-by-step explanation:
to write an equation in slope-intercept form, y = mx + b, calculate the slope, m, as rise/ run
The difference in y-values, rise, is –2
The difference between x-values is 2
–2/2 = m, the slope is –1
substitute for m, and it use any set of given y and x values in the equation to solve for b.
y= mx +b
–2 = –1(3) + b. Add 3 to both sides.
3 –2 = 3 –3 + b
1 = b
use the calculated m and b to write the equation with y and x
y = –x + 1
Alene wants to buy a pencil pouch the cost 16.00. She must also pay 5% sales tax. If she pays with a $20 bill,how much change will she receive back
Answer:
$3.20
Step-by-step explanation:
The price of the Pencil is $16
Tax payable on the pencil is 5%*16 = $0.8
Total amount payable is = $16 + $0.8 = $16.8.
So, If she pays with a $20 bill, then the change she will receive is $3.20 ($20 - $16.8)

Upon studying low bids for shipping contracts, a microcomputer manufacturing company finds that intrastate contracts have low bids that are uniformly distributed between 22 and 29, in units of thousands of dollars. (a) Find the probability that the low bid on the next intrastate shipping contract is below $25,000. (Round your answer to four decimal places.)
Answer:
0.4286 = 42.86% probability that the low bid on the next intrastate shipping contract is below $25,000.
Step-by-step explanation:
A distribution is called uniform if each outcome has the same probability of happening.
The uniform distributon has two bounds, a and b, and the probability of finding a value lower than x is given by:
[tex]P(X < x) = \frac{x - a}{b - a}[/tex]
Uniformly distributed between 22 and 29, in units of thousands of dollars.
This means that [tex]a = 22, b = 29[/tex].
(a) Find the probability that the low bid on the next intrastate shipping contract is below $25,000.
This is P(X < 25). So
[tex]P(X < 25) = \frac{25 - 22}{29 - 22} = 0.4286[/tex]
0.4286 = 42.86% probability that the low bid on the next intrastate shipping contract is below $25,000.

I need help converting 3/5 into a decimal what should I write?
Explanation: Decimals represent fractions
with denominators of 10, 100, 1000, and so on.
Therefore, in order to write 3/5 as a decimal, we must first find a
fraction equivalent to 3/5 with a denominator of 10.
So we multiply the numerator and denominator
of 3/5 by 2 to get the equivalent fraction 6/10.
Since 6/10 is written as the decimal 0.6,
3/5 must be equivalent to 0.6.
