If you have $90 to start a business and you can’t exceed that amount, how would you write an inequality for this
Answers
Let's say "b" represents Business
You may write this 3 different ways.
b=$90
b<$90 (meaning b is less than $90, this is my least favorite way, as it doesn't quite capture what this question requires)
b is less than or equal to $90. This site, unfortunately, does not allow one to use the sign that represents "less than or equal to", but I'll give you a picture of what it looks like:
The sign that means "less than or equal to" is the MOST accurate way to show that the money you have for your business must be LESS than, or EQUAL to the said amount, which is $90.

The perimeter of a rectangular garden is 90 meters. the length is 6 meters longer than twice the width. find the dimensions of the garden.
Answers
The formula for the Perimeter of a rectange is P = 2L + 2W.
Here, P = 2(2W + 6) + 2W = 90 (all dimensions in meters).
Then 4W + 12 + 2W = 90; 6W = 78; W=13 meters. Then L = 2W + 6=
2(13) + 6 = 32 meters.
Check: Does P come out to 90 meters when W = 13 m and L = 32 meters?
P = 2(13 m) + 2(32 m) = 26 m + 64 m = 90 m. YES.
W = 13 m; L = 32 m (answer)
The width of the rectangular garden is 13 meters and the length is 32 meters.
Explanation:The problem pertains to perimeter of a rectangle, which is calculated by the formula 2*(length + width). You're told the perimeter is 90 meters, and that the length is 6 meters longer than twice the width.
So, let's denote the width as x. Then the length would be 2x + 6.
Substitute these expressions into the perimeter formula: 2*(x + 2x + 6) = 90. Simplifying this equation gives us 6x + 12 = 90.
Subtract 12 from both sides of the equation to get 6x = 78. Finally, divide each side by 6 to solve for x, which results in x = 13.
Since x represents the width of the rectangular garden, the width is 13 meters. The length, which is twice the width plus 6, is 2*13 + 6 = 32 meters.

Let's try something new:
Perimeter = 6x - 20 = 2W + 2L, but here W = L because this is a square.
Then 6x - 20 = 4W = 4x
Then 6x - 4x = 20; 2x = 20; x = 10.
This is a square with side length 10. Its perimenter is thus 4(10) = 40.
Does 6(10) - 20 = 40? Yes. So, x = 10.
what is the indicated operation of
10 3/7 + 19 5/9
Answers
Final answer:
To find the sum of mixed numbers, convert them into improper fractions and then add the fractions together. The answer here is 1889/63.
Explanation:
The student’s question “what is the indicated operation of 10 3/7 + 19 5/9” asks to perform the operation of addition between two mixed numbers. The indicated operation is addition. To add these mixed numbers, you first add the whole numbers (10 + 19) and then add the fractions (3/7 + 5/9). When adding fractions, find a common denominator, in this case, 63, and convert the fractions to have this common denominator before adding.
To find the sum of mixed numbers, we first convert them into improper fractions.
10 3/7 becomes 73/7 and 19 5/9 becomes 176/9.
Then, we add the numerator of the fractions and keep the denominator the same. So, 73/7 + 176/9 = (73 * 9 + 7 * 176)/(7 * 9). Which gives 1889/63.
two crooks rob a bank and flee to the east at 66mph. in 30 minutes, the police follow them in a helicopter, flying 132mph. how long will it take for police to overtake the robbers?
Answers
To calculate this, firstly we need the initial lead of the robbers in miles before the police starts to chase, which is the product of the speed of the robbers and the time before the police starts to chase. Given that the speed of robbers is 66 mph and the time before the police chase is 0.5 hours, multiplying these gives a robber lead of 33 miles.
Next, to determine how quickly the police can close this gap, we need to calculate the relative speed of the police helicopter compared to the robbers. The speed of the police is 132 mph and the speed of the robbers is 66 mph, the difference between these two speeds is the relative speed. So, 132 mph - 66 mph gives a relative speed of 66 mph.
Finally, the time it will take for the police to catch up to the robbers - the catchup time - is the ratio of the initial lead of the robbers to the relative speed of the police. Here it is 33 miles divided by 66 mph, this yields a catchup time of 0.5 hours.
Therefore, it will take the police 0.5 hours to overtake the robbers.

Messages arrive to a computer server according to a poisson distribution with a mean rate of 10 per hour. determine the length of an interval of time such that the probability that no messages arrive during this interval is 0.90.
Answers
The Poisson distribution is f(k) = λ^k * e^(-λ) / k!
Where:λ is the expected number of circumstances of the occurrence during interval t ;
In the problem, r = 10 calls/hour. Where it is also = 1/360 calls/sec , therefore λ = t/360 calls during interval t ;
f(k) is the probability of exactly "k" occurrences;
So based from the problem: f = 0.9 ; k = 0 ; λ = t/360
0.9 = (t/360)^0 * e^(-t/360) / 0!
0.9 = e^(-t/360)
t = -360 ln 0.9 = 37.93 s
it is approximated: 38 s is the interval with 0.9 probability of no calls received

What is the probability a sample of 90 test takers will provide a sample mean test score within 10 points of the population mean of 502 on the critical reading part of the test (to 4 decimals)? 0.6578?
Answers
Critical Reading 502
Mathematics 515
Writing 494
Assume that the population standard deviation on each part of the test is σ = 100.
We find the probability that a sample of 90 test takers will provide a sample mean test score within 10 points of the population mean of 502 on the critical reading part of the test (to 4 decimals) as follows:
Within 10 points of 502 implies (502 - 10, 502 + 10) = (492, 512).
Because the sample is large, we assume normal distribution.
The probability that the mean statistic of sample data is between two points (a, b) is given by:
[tex]P(a\ \textless \ \bar{x}\ \textless \ b)=P\left( \frac{b-\mu}{\sigma/\sqrt{n}} \right)-P\left( \frac{a-\mu}{\sigma/\sqrt{n}} \right)[/tex]
Thus,
[tex]P(492\ \textless \ \bar{x}\ \textless \ 512)=P\left( \frac{512-502}{100/\sqrt{90}} \right)-P\left( \frac{492-512}{100/\sqrt{90}} \right) \\ \\ = P\left(\frac{10}{10.5409} \right)-P\left(\frac{-10}{10.5409} \right)=P(0.9487)-P(-0.9487) \\ \\ =P(0.9487)-[1-P(0.9487)]=2P(0.9487)-1=2(0.82861)-1 \\ \\ =1.65722-1=0.65722[/tex]
Therefore, the probability that a sample of 90 test takers will provide a sample mean test score within 10 points of the population mean of 502 on the critical reading part of the test (to 4 decimals) is 0.6572.
The probability that the sample mean of 90 test takers falls within 10 points of the population mean of 502 is approximately 0.6578.
To find the probability that a sample of 90 test takers will provide a sample mean test score within 10 points of the population mean of 502 on the critical reading part of the test, we need to calculate the probability using the standard normal distribution.
Given:
- Population mean [tex](\(\mu\))[/tex]: 502
- Sample size[tex](\(n\))[/tex]: 90
- Standard deviation [tex](\(\sigma\))[/tex] of the population (assumed known or provided): Let's assume it is 100 (for example purposes).
We are looking for the probability that the sample mean[tex](\(\bar{X}\))[/tex] falls within 10 points of the population mean (502 ± 10).
Step 1: Calculate the standard error of the mean (SEM):
[tex]\[ SEM = \frac{\sigma}{\sqrt{n}} \][/tex]
[tex]\[ SEM = \frac{100}{\sqrt{90}} \][/tex]
[tex]\[ SEM = \frac{100}{9.4867} \][/tex]
[tex]\[ SEM \approx 10.548 \][/tex]
Step 2: Convert the deviation of ±10 points from the mean into a z-score using the standard normal distribution:
[tex]\[ z = \frac{\text{sample mean} - \mu}{SEM} \][/tex]
For the upper bound:
[tex]\[ z_{\text{upper}} = \frac{502 + 10 - 502}{10.548} \][/tex]
[tex]\[ z_{\text{upper}} = \frac{10}{10.548} \][/tex]
[tex]\[ z_{\text{upper}} \approx 0.9497 \][/tex]
For the lower bound:
[tex]\[ z_{\text{lower}} = \frac{502 - 10 - 502}{10.548} \][/tex]
[tex]\[ z_{\text{lower}} = \frac{-10}{10.548} \][/tex]
[tex]\[ z_{\text{lower}} \approx -0.9497 \][/tex]
Step 3: Find the cumulative probabilities using the standard normal distribution table or a calculator:
[tex]\[ P(-0.9497 \leq Z \leq 0.9497) \][/tex]
Using a standard normal distribution table or a calculator, find:
[tex]\[ P(Z \leq 0.9497) \approx 0.8289 \][/tex]
[tex]\[ P(Z \leq -0.9497) \approx 0.1711 \][/tex]
Step 4: Calculate the probability that the sample mean falls within 10 points of the population mean:
[tex]\[ P(-0.9497 \leq Z \leq 0.9497) = 0.8289 - 0.1711 \][/tex]
[tex]\[ P(-0.9497 \leq Z \leq 0.9497) = 0.6578 \][/tex]
Therefore, the probability that a sample of 90 test takers will provide a sample mean test score within 10 points of the population mean of 502 is approximately [tex]{0.6578} \).[/tex]
