Since there is no value of x that will ever make this a true statement, the solution to the equation above is “no solution” The solution x = 0 means that the value 0 satisfies the equation, so there is a solution. “No solution” means that there is no value, not even 0, which would satisfy the equation. and Basically just means for all numbers from minus infinity to infinity. We say real x to distinguish from complex numbers. 0. general ebriety. and Basically just means for all numbers from minus infinity to infinity.

I need to know how to work fractions word problems like Leon's older brother is 4 3/4 feet tall. Leon is 1/3 foot shorter than his brother. How tall is Leon?
Answer:
4 5/12 feet tall
Step-by-step explanation:
Find the LCM first. The LCM is the lowest common multiple between the two denominators. The LCM in this problem is 12, so you multiply each fraction until the denominators equal 12
4 3/4 -> 4 9/12
1/3 -> 4/12
Now it's much easier to solve. 4 9/12 - 4/12 = 4 5/12 feet tall

Suppose a subdivision on the southwest side of Denver, Colorado, contains 1,500 houses. The subdivision was built in 1983. A sample of 120 houses is selected randomly and evaluated by an appraiser. If the mean appraised value of a house in this subdivision for all houses is $228,000, with a standard deviation of $8,500, what is the probability that the sample average is greater than $229,500?
Answer:
0.0268 = 2.68% probability that the sample average is greater than $229,500
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.
Single house:
The mean appraised value of a house in this subdivision for all houses is $228,000, with a standard deviation of $8,500, which means that [tex]\mu = 228, \sigma = 8.5[/tex]
Sample:
Sample of 120, so, by the central limit theorem, [tex]n = 120, s = \frac{8.5}{\sqrt{120}} = 0.7759[/tex]
What is the probability that the sample average is greater than $229,500?
This is 1 subtracted by the pvalue of Z when X = 229.5. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{229.5 - 228}{0.7759}[/tex]
[tex]Z = 1.93[/tex]
[tex]Z = 1.93[/tex] has a pvalue of 0.9732
1 - 0.9732 = 0.0268
0.0268 = 2.68% probability that the sample average is greater than $229,500

The nth term of the GP is given by
[tex]10 - \frac{10}{ {2}^n{}}[/tex]
find the first 4 terms
Answer:
Step-by-step explanation:
hello :
An = 10 -10/2^n
the first 4 terms are :
A1 = 10 -10/2^1 = 10-5
A1 = 5
A2 = 10 -10/2^2 = 10-10/4 = 10-5/2 = (20-5)/2
A2 = 15/2
A3 = 10 -10/2^3 = 10-10/8 =10- 5/4 = (40-5)/4
A3 = 35/4
A4 = 10 -10/2^4 = 10-10/16 = 10-5/8 = (80-5)/8
A4 = 75/8

Answer:
Hence, first one will be 1/3 and second one will be 1/6
Step-by-step explanation:
1. Let the blank space be x then,
[tex]3 \frac{2}{3} + x = 4[/tex]
[tex]x = 4 - 3 \frac{2}{3} [/tex]
[tex]x = \frac{12 - 11}{3} [/tex]
[tex]x = \frac{1}{3} [/tex]
2. Let the blank be x then,
[tex]x + \frac{2}{3} = \frac{5}{6} [/tex]
[tex]x = \frac{5}{6} - \frac{2}{3} [/tex]
[tex]x = \frac{5 - 4}{6} [/tex]
[tex]x = \frac{1}{6} [/tex]

Sherbrooke, Quebec is 210 miles from Boston, MA. A train leaves Boston at noon and arrives in Sherbrooke at 4:40 PM. On the return trip to Boston, the train travels 50.4 mph. How many times greater (or less) is the train’s speed on the return trip to Boston than on the trip to Sherbrooke?
9514 1404 393
Answer:
1.12 times as great
Step-by-step explanation:
The speed from Boston is ...
(210 mi)/(4 2/3 h) = 45 mi/h
Then the speed to Boston is ...
50.4/45 = 1.12 . . . times as great

Answer:
3,480
Step-by-step explanation:
After 4 years she had to repay 3,480, i did this one before and got it right hope it helped have a nice day!
[tex]\color{plum}\tt\bold{(b) \: \$3480 }[/tex]
Steps to derive correct option :Money Maria borrowed = $3000
Percentage of simple interest per annum = 4%
Time she took to repay the money she borrowed = 4 years
We know that :
[tex]\color{hotpink}\tt \: Simple \: interest = \color{plum}\frac{principal \times rate \times time}{100} [/tex]
In this case :
Principal = $3000
Rate = 4%
Time = 4 years
Which means. the simple interest :
[tex] = \tt \frac{3000 \times 4 \times 4}{100} [/tex]
[tex] = \tt \frac{48000}{100} [/tex]
[tex]\color{plum} =\tt\$ 480[/tex]
Thus, the interest she has to pay = $480
We know that :
[tex]\color{hotpink}\tt \: Amount \color{plum}= principal + interest[/tex]
Then, the Amount Maria has to pay :
[tex] =\tt 3000 + 480[/tex]
[tex]\color{plum} =\tt \$3480[/tex]
Thus, the amount Maria has to repay after 4 years = $3480
Therefore, the correct option is (b) $3480
