Condos in norwood go up in value by 10% each year. if gregory family's condo is now worth $160,000, what will it be worth in 5 years? i will give brainliest to the person that answers first.
Answer:
$257,681.60
Step-by-step explanation:
What's happening here is called "compounding," and the appropriate formula is A = P(1 + r)^t, where r is the rate of increase as a decimal fraction.
With the given data, we have:
A = $160,000(1 + 0.10)^(5), or:
= $160,000(1.10)^5, or:
= $160,000(1.6105) = $257,681.60 : condo value after 5 years
A classroom has a presentation system that consists of four components, each of which must activate if the system is to work adequately. The first component has a reliability of 0.97, the second component has a reliability of 0.99, the third component has a reliability of 0.97, and the fourth component has a reliability of 0.93. What is the overall system reliability
Answer:
0.87
Step-by-step explanation:
According to the scenario, computation of given data are as follows,
As, each must be activated, this shows that components are in series.
So, we can calculate reliability of system by using following formula,
System reliability with components in series = System reliability 1 × System reliability 2 × System reliability 3 × System reliability 4
So, overall system reliability = 0.97 × 0.99 × 0.97 × 0.93
overall system reliability = 0.866 or 0.87

Write the quadratic equation whose roots are 6 and -6, and whose leading coefficient is 2.
(Use the letter x to represent the variable.)
Answer:
[tex]2x^2-6[/tex]
Step-by-step explanation:
If a quadratic equation has a root at a certain point, the x value must equal. zero. If we want to have the function reach 6 and -6 as roots:
x = 6
x - 6 = 0
x = -6
x + 6 = 0
Combining the two we get (x+6)(x-6) which will give us a quadratic equation.
Expanding: [tex]x^2-6x+6x-6 = x^2-6[/tex]
The leading coefficient is the number before the variable with the highest power, which is 2: [tex]2x^2-6[/tex]
Expand
(2x + 7)(x - 5)
Answer:
[tex]2x^{2}[/tex]- 3x - 35
Step-by-step explanation:
(2x + 7)(x - 5) = [tex]2x^{2}[/tex] - 10x + 7x - 35 = [tex]2x^{2}[/tex]- 3x - 35
To expand multiply each tern in one set of parenthesis by each term in the other set:
(2x+7) (x-5)
Set up each multiplication:
2x*x + 2x*-5 + 7*x + 7*-5
Simplify:
2x^2 -10x +7x -35
Combine like terms:
2x^2-3x-35
According to the Oxnard College Student Success Committee report in the previous year, we believe that 25% of students struggle in their classes because they don't spend more than 8 hours studying independently outside of a 4-unit class. For this year, you would like to obtain a new sample to estimate the proportiton of all Oxnard students who struggle in their classes because they don't study enough outside of the classrooms. You would like to be 99% confident that your estimate is within 1% of the true population proportion. How large of a sample size is required? Do not round mid-calculation

Alejandro was curious if sample median was an unbiased estimator of population median. He placed ping pong balls numbered from 000 to 323232 in a drum and mixed them well. Note that the median of the population is 161616. He then took a random sample of 555 balls and calculated the median of the sample. He replaced the balls and repeated this process for a total of 505050 trials. His results are summarized in the dotplot below, where each dot represents the sample median from a sample of 555 balls. A dot plot for a sample median has a scale from 0 to 30. The number of dots for each is as follows. 0, 0. 1, 0. 2, 0. 3, 0. 4, 1. 5, 1. 6, 2. 7, 1. 8, 0. 9, 1. 10, 5. 11, 3. 12, 2. 13, 4. 14, 1. 15, 3. 16, 4. 17, 4. 18, 1. 19, 2. 20, 4. 21, 2. 22, 0. 23, 1. 24, 2. 25, 1. 26, 1. 27, 0. 28, 2. 29, 2. 30, 0. Based on these results, does sample median appear to be a biased or unbiased estimator of population median
Answer:
Sample median appears to be an unbiased estimator of the population median
Step-by-step explanation:
The sample median appears to be centered near 16
The required sample median appears to be an unbiased estimator of the population median
What are dot plots?A dot plot defined as a collection of plots or dot diagrams is a simple form of data illustration that consists of data points plotted in the form of dots on a graph with axes.
Here,
He placed ping pong balls numbered from 0 to 32 in a drum and mixed them well.
The median of the population is 16. So the sample median appears to be centered near the 16. He replaced the balls and repeated this process for a total of 50 trials.
When plotting the dot plot of the given system, it is summarised that the sample median appears to be an unbiased estimator of the population median.

Laura received a $80 gift card for a coffee store. She used it in buying some coffee that cost $7.96 per pound. After buying the coffee, she had $56.13
left on her card. How many pounds of coffee did she buy?
Answer:
Step-by-step explanation:
Hi.
I can help.
First what we want to do is take what she had before spending any money and then take what she had after.
So :
$80.00
and
$56.13
Now to find how much she spent we can subtract these two numbers like so :
80.00 - 56.13
=
23.87
So now we know she spent a total of $23.87 on coffee in pounds.
Now if each pound of coffee costs $7.96 we can divide this into how much she spent $23.87 to find the total amount of pounds she bought for $7.96.
So:
23.87 / 7.96
=
About 3
She bought 3 pounds of coffee.

Let f(x)=x²+5x and g(x)=4x-3. Perform the composition or operation indicated.
(f/g)(-3)
9514 1404 393
Answer:
2/5
Step-by-step explanation:
Put the numbers in the equations and do the arithmetic.
f(-3) = (-3)² +5(-3) = 9 -15 = -6
g(-3) = 4(-3) -3 = -12 -3 = -15
Then the composition is ...
(f/g)(-3) = f(-3)/g(-3) = -6/-15
(f/g)(-3) = 2/5

when the denominators are the same, the fraction with the _____ is the largest fraction
Bigger numerator
Means bigger fraction
When the denominators are the same, the fraction with the bigger numerator is the largest fraction .
What is the fraction?In mathematics, a fraction is represented by a number that identifies a portion of a whole. A fraction is a component or section taken from a whole, which can be any number, a certain amount, or an object.
It is simpler to identify the larger or smaller fraction when comparing fractions with the same denominator. We may easily find the fraction with the larger numerator by first determining whether the denominators are the same.
Therefore, when the denominators are the same, the fraction with the bigger numerator is the largest fraction .

Answer:
5x^3-x+2
Step-by-step explanation:
We rearrange the formula grouping x together but preserving subtraction and start numbers from left.
- 2 -3x + 2x + 5x^3 +4
= -2+4
= 2
-3x +2x = -1x = -x
= 5x^3 +2 - x
= 5x^3 -x + 2
We cannot distribute unless we had the given values for x
if x = 1 and we were told this, then the equation would be set to zero +2 as you would be left with x^3 = 1 and x = 1 and 1-1 = 0
Then you would just need to apply +2 = 2.
But in standard form we leave the amounts 5x^3 -x +2
