Answer:
The correct option is 1. The normal distribution with mean 3 and standard deviation 4 has a wider spread.
Step-by-step explanation:
Normal distribution is defined by two variables, mean and standard deviation.
[tex]Z=\frac{X-\mu}{\sigma}[/tex]
The spread of a normal distribution is not dependent on mean, it is completely dependent of standard deviation. Larger standard deviation means wider spread.
It is given that first normal distribution has
[tex]\mu_1=3[/tex]
[tex]\sigma_1=4[/tex]
Second normal distribution has
[tex]\mu_2=4[/tex]
[tex]\sigma_2=3[/tex]
Since [tex]\sigma_1>\sigma_2[/tex], therefore the normal distribution with mean 3 and standard deviation 4 has a wider spread.
Hence the correct option is 1.
Final answer:
The normal distribution with a mean of 3 and a standard deviation of 4 has a wider spread than a normal distribution with a mean of 4 and a standard deviation of 3, as the spread is determined by the standard deviation.
Explanation:
The question is asking which of the two normal distributions has a wider spread. The spread of a normal distribution is determined by its standard deviation. A normal distribution with a higher standard deviation will have a wider spread. In this case, the normal distribution with a mean of 3 and a standard deviation of 4 will have a wider spread compared to the normal distribution with a mean of 4 and a standard deviation of 3. Thus, the statement 'the normal distribution with mean 4 and standard deviation 3 has the wider spread' is incorrect.
In a normal distribution, as the standard deviation increases, the distribution curves become wider and shorter, reflecting a greater spread in the data. Because both distributions are normally distributed, we can compare the standard deviations directly to determine the spread: a standard deviation of 4 indicates a wider spread than a standard deviation of 3.

The cruise control function on Georgina's car should keep the speed of the car within 3 miles per hour of the set speed. The set speed is 55 miles per hour. Write a compound inequality to show the leaves that are within each range. Then graph the solutions.
Answer:
Given,
Set speed of car = 55,
∵ The speed of the car within 3 miles per hour of the set speed.
So, the maximum speed of car = 55 + 3,
And, the minimum speed of car = 55 - 3
Let x shows the current speed of car,
x ≤ 55 + 3 or x ≥ 55 - 3
x - 55 ≤ 3 or x - 55 ≥ - 3
x - 55 ≤ 3 or -(x-55) ≤ 3
⇒ | x-55 | ≤ 3
Which is the required compound inequality,
Now, 55 - 3 ≤ x ≤ 55 + 3
52 ≤ x ≤ 58
⇒ [52, 58]
Which is the solution of the above compound inequality.
Also, the graph is shown below.

Why is it important to take note of skipped check numbers?
A. Skipping a check wastes the check and will end up costing money.
B. Locating skipped checks helps to identify where the fees come from.
C. Skipped checks were written for more money than was available in the account.
D. A skipped check has not been cashed or deposited.
Answer:
D. A skipped check has not been cashed or deposited.
Step-by-step explanation:
We can say that a skipped check number means the check has not been cashed yet.
If we see the check book and there is a gap between the check numbers that you have written, then that means the missing number checks are not processes yet. The processing can be depositing or withdrawing/cashing.
So, the correct answer here is D. A skipped check has not been cashed or deposited.

Write an equation that represents degrees fahrenheit in terms of degrees celsius. let xx represent the temperature in degrees celsius and let yy represent the temperature in degrees fahrenheit.
An equation is formed of two equal expressions. An equation that represents degrees Fahrenheit in terms of degrees celsius is y=(9/5)x+32.
What is an equation?
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The equation to covert degrees fahrenheit to degrees celsius is given as,
(C × 9/5) + 32 = F
where C represents temperature in degrees Celcius and F represents the temperature in degrees Fahrenheit.
Now, we need to represent the degree Celcius by x, while the degree Fahrenheit by y. Therefore, the above equation can be rewritten as,
y = (x × 9/5) + 32
y = (9/5)x + 32
Hence, an equation that represents degrees Fahrenheit in terms of degrees celsius is y=(9/5)x+32.

Laura drove to the mountains last weekend. there was heavy traffic on the way there, and the trip took 8 hours. when laura drove home, there was no traffic and the trip only took 6 hours. if her average rate was 16 miles per hour faster on the trip home, how far away does laura live from the mountains
To find the distance Laura lives from the mountains, calculate her average speed when driving to the mountains and use the time taken during the trip. With the given speeds and travel times, the distance can be determined using a simple equation.
Explanation:To find the distance Laura lives from the mountains:
Let x be Laura's average speed when driving to the mountains.Since Laura drove 16 mph faster on the way home, her speed returning was x+16 mph.Distance to mountains = x * 8 (hours) and distance from mountains = (x+16) * 6 (hours).Set up the equation: x * 8 = (x+16) * 6 to solve for x.Once x is found, the distance Laura lives from the mountains can be calculated as x * 8.

Suppose that you have he option to buy an item with either cash or credit. Under which condition would you use credit?
Answer:
If you want to build a good credit history
Step-by-step explanation:
Buying something in order to build a good credit history does not benefit in the short run such as any financial or non-financial benefit.
However, when need arises to make request for a large sum of loan in the long run (such as buying house, purchasing vehicle or capital for investing in business) from the financial institution or any other credit providers, then the good credit history would be winning key factor for obtaining the loan.
if a and b are the measures of two first quadrant angles and sin a = 4/9 and sin b = 2/5 find sin (a+b)
The sine of the sum of two angles a and b, with sin a = 4/9 and sin b = 2/5, is calculated using the sine addition formula and is approximately 32.24/45.
To find sin(a+b) when given sin a = 4/9 and sin b = 2/5, we use the sine addition formula:
sin(a+b) = sin(a)cos(b) + cos(a)sin(b)
Since we have the sine values, but not the cosine values, we need to find cos(a) and cos(b). Knowing that [tex]sin^2(\theta) + cos^2(\theta) = 1[/tex]for any angle theta, we can find the cosines:
For cos(a): [tex]cos^2(a) = 1 - sin^2(a) = 1 - (4/9)^2 = 1 - 16/81 = 65/81[/tex]. So, [tex]cos(a) = \sqrt{(65/81)} = 8/9[/tex] (since a is in the first quadrant where cosine is positive).For cos(b): [tex]cos^2(b) = 1 - sin^2(b) = 1 - (2/5)^2 = 1 - 4/25 = 21/25[/tex]. So, cos(b) = [tex]\sqrt{(21/25)}= 4.6/5[/tex] (since b is in the first quadrant where cosine is positive).Now, we plug these values into the formula:
sin(a+b) = (4/9)(4.6/5) + (8/9)(2/5) = 16.24/45 + 16/45 = 32.24/45
Thus, the sine of the sum of the two angles a and b is approximately 32.24/45.

what is the area of a circular mirror with a radius of 10 cm?
Final answer:
The area of a circular mirror with a radius of 10 cm is calculated using the formula πr², which results in an area of 314.16 cm².
Explanation:
The area of a circular mirror can be calculated using the formula πr², where π (pi) is approximately 3.1416 and r is the radius of the circle. Given the radius of the circular mirror as 10 cm, we can substitute this value into the formula to find the area.
Area = π × (10 cm)²
A = 3.1416 × 100 cm²
A = 314.16 cm²
Therefore, the area of the circular mirror is 314.16 cm².
