Answer:
A) 1790.85
Step-by-step explanation:
Hi there!
In order to solve this problem, you’ll need to use the compound interest formula [tex]x = p(1 + \frac{r}{n} )^n^t[/tex]
p will be your principle, or starting amount, which is 1,000.
r will be your percentage, which is 0.06.
n will be the amount of times interest is compounded, since this question says compounded anually, your compound will be 1.
t is the time in years it is compounded, which is 10.
When the numbers are plugged in, we get [tex]x = 1,000(1 + \frac{0.06}{1})^1^0[/tex]
When we solve for this, we get 1790.85.
Hope this helps! :)

Answer:
C) (y - 1)(y - 5)
Step-by-step explanation:
Hi there!
First you separate your expression into groups.
[tex](y^2-5y)(-1y+5)[/tex]
Now we take the common multiple out of each.
[tex]y(y - 5)-1(y - 5)[/tex]
Since we have two (y - 5)s, we can pull it out of the equation as its own common multiple.
After we do that, we are left with y - 1. (we got this from taking the common multiples out)
Now we are just left with (y - 5)(y - 1)
Hope this helped!

In a lab experiment, the decay of a radioactive isotope is being observed. At the beginning of the first day of the experiment the mass of the substance was 1000 grams and mass was decreasing by 14% per day. Determine the mass of the radioactive sample at the beginning of the 10th day of the experiment. Round to the nearest tenth (if necessary).
Answer:
120.91 grams
Step-by-step explanation:
multiply the initial amount by the percent that will remain to the power of n-1, n being the term number, or how many days that have passed.

A quality control expert at Glotech computers wants to test their new monitors. The production manager claims they have a mean life of 75 months with a standard deviation of 5 months. If the claim is true, what is the probability that the mean monitor life would be greater than 74.4 months in a sample of 85 monitors
Answer:
86.65% probability that the mean monitor life would be greater than 74.4 months in a sample of 85 monitors
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal probability distribution
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore 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 pvalue, 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.
In this question:
Population: [tex]\mu = 75, \sigma = 5[/tex]
Sample of 85: [tex]n = 85, s = \frac{5}{\sqrt{85}} = 0.5423[/tex]
If the claim is true, what is the probability that the mean monitor life would be greater than 74.4 months in a sample of 85 monitors
This is 1 subtracted by the pvalue of Z when X = 74.4. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{74.4 - 75}{0.5423}[/tex]
[tex]Z = -1.11[/tex]
[tex]Z = -1.11[/tex] has a pvalue of 0.1335
1 - 0.1335 = 0.8665
86.65% probability that the mean monitor life would be greater than 74.4 months in a sample of 85 monitors

Answer:
y=½x+0
Step-by-step explanation:
∆y/∆x
=1-½/2-1=½
the first part of the rule is ½x
Plug in x=3
½×3=3/2
when x=5
½×5=4/2
Therefore the rule is y=½x+0

Calculator, Z table
Yuki and Zana are on a swimming team. They often compete against each other in the 100 meter freestyle
race. Yuki's times in this race are normally distributed with a mean of 80 seconds and a standard deviation
of 4.2 seconds. Zana's times are also normally distributed with a mean of 85 seconds and a standard
deviation of 5.6 seconds. We can assume that their times are independent.
Suppose we choose a random 100 meter freestyle race and calculate the difference between their times.
Find the probability that Yuki's time is faster than Zana's.
You may round your answer to two decimal places.
P (Yuki faster)
Answer:
0.2389 = 23.89% probability that Yuki's time is faster than Zana's.
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.
Find the probability that Yuki's time is faster than Zana's.
That is, the subtraction of Yuki's time by Zana's time has to be higher than 0.
When we subtract normal distributions, the mean is the subtraction of the means. So
[tex]\mu = 80 - 85 = -5[/tex]
The standard deviation is the square root of the sum of the variances. So
[tex]\sigma = \sqrt{4.2^2+5.6^2} = 7[/tex]
We have to find 1 subtracted by the pvlaue of Z when X = 0. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{0 - (-5)}{7}[/tex]
[tex]Z = 0.71[/tex]
[tex]Z = 0.71[/tex] has a pvalue of 0.7611
1 - 0.7611 = 0.2389
0.2389 = 23.89% probability that Yuki's time is faster than Zana's.
In this exercise we have to use knowledge about probability to calculate the probability of faster time, so we have to:
probability that Yuki's time is faster than Zana's.
When the distribution is normal, we use the z-score formula. In a set with mean and standard deviation , the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.
Find the probability that Yuki's time is faster than Zana's. That is, the subtraction of Yuki's time by Zana's time has to be higher than 0. When we subtract normal distributions, the mean is the subtraction of the means. So:
[tex]\mu= 80-85=-5[/tex]
The standard deviation is the square root of the sum of the variances. So:
[tex]\sigma= \sqrt{(4.2)^2+(5.6)^2} = 7[/tex]
We have to find 1 subtracted by the p-value of Z when X = 0. So:
[tex]Z= \frac{X-\mu}{\sigma}\\Z= \frac{0-(-5)}{7}\\Z= 0.71[/tex]
Has a p-value of 0.7611:
[tex]1 - 0.7611 = 0.2389[/tex]

Step-by-step explanation:
Since this is a 30° 60° 90°, the hypotenuse is 2 times greater than the small leg. We can use this information to make an equation and solve for x.
2x = √8
x = √2
Therefore, x = √2.
