Answer:
True
Step-by-step explanation:
In a normal distribution, 68% of the data falls within 1 standard deviation of the mean is true.
What is a normal distribution?A normal distribution is a continuous probability distribution that describes a symmetric, bell-shaped curve of data.
It is also known as a Gaussian distribution or a bell curve.
The normal distribution is used to model many real-world phenomena, such as measurements of height, weight, blood pressure, and IQ scores, among others.
We have,
In a normal distribution, 68% of the data falls within 1 standard deviation of the mean.
This is known as the Empirical Rule or the 68-95-99.7 rule, which states that:
- approximately 68% of the data falls within one standard deviation of the mean
- approximately 95% of the data falls within two standard deviations of the mean
- approximately 99.7% of the data falls within three standard deviations of the mean.
Thus,
In a normal distribution, 68% of the data falls within 1 standard deviation of the mean is true.

Using the Pythagorean theorem what is the distance between (5,-3) and (9,1)
Step-by-step explanation:
Distance between (5,-3) and (9,1)=√(9-5)^2+(1-(-3))^2
=√4^2+4^2
=√16+16
=√32 units
It's not possible to calculate the distance between these points by pythagoras theorem .We can easily calculate it by distance formula I.e.√(x2-x1)^2+(y2-y2)^2
Find the slope for the 4 problems
Need help ASAP!

Answer:
1: m = 2
2: m = -1
3: m = 7/8
4: m=0
Step-by-step explanation:
Before I begin, ALWAYS REMEMBER, the slope formula is:
y2 - y1 / x2 - x1 = slope
1:
(4,4) (6,8)
y2: 8
y1: 4
x2: 6

Gas prices are projected to increase 124% by April. A gallon of gas currently costs $3.17. What is the
projected cost of a gallon of gas in April?
Answer: $7.1
Step-by-step explanation:
Since the gallon of gas currently costs $3.17 and the prices are projected to increase 124% by April. Then, the projected cost of a gallon of gas in April will be:
= $3.17 × (100% + 124%)
= $3.17 × 224%
= $3.17 × 2.24
= $7.1
Therefore, the projected cost will be $7.1

Samantha saw two bottles of ketchup at the store for the same price. One bottle contained 4 pints of ketchup, and the other contained 1.25 quarts of ketchup.
Which bottle was the better bargain?
Answer:
The 4 pint ketchup bottle was the better bargain.
Step-by-step explanation:
To find which bottle was the better bargain, find which one had the most amount of ketchup in it.
In one quart, there are 2 pints.
Convert the 1.25 quart bottle to pints by multiplying 1.25 by 2:
1.25(2)
= 2.5
Since 4 is larger than 2.5, the 4 pint bottle of ketchup has more.
So, the 4 pint ketchup bottle was the better bargain.

The area of a rectangle is (81x2 − 4y2) square units. Determine the dimensions of the rectangle by factoring the area expression completely. Show your work. (5 points)
Answer:
The dimension of the rectangle are [tex]9\cdot x - 2\cdot y[/tex] units and [tex]9\cdot x + 2\cdot y[/tex] units, respectively.
Step-by-step explanation:
Geometrically speaking, the area of a rectangle is equal to the product of its base and its height. If we know that area of the figure is [tex]81\cdot x^{2} - 4\cdot y^{2}[/tex] square units, then we proceed to factor the expression:
1) [tex]A = 81\cdot x^{2} - 4\cdot y^{2}[/tex] Given
2) [tex]A = (9\cdot x -2\cdot y)\cdot (9\cdot x + 2\cdot y)[/tex] [tex]a^{2} - b^{2} = (a + b) \cdot (a - b)[/tex]/Result
The dimension of the rectangle are [tex]9\cdot x - 2\cdot y[/tex] units and [tex]9\cdot x + 2\cdot y[/tex] units, respectively.
Answer:
(9x + 2y)(9x - 2y)
Step-by-step explanation:
The rule: a^2 - b^2 = (a + b)(a - b)
81x^2 - 4y^2
And we have a = 9x and b = 2y
and our factors are.
(9x + 2y)(9x - 2y)
so the the dimensions are 9x + 2y and 9x - 2y

Answer:
2) Slope=10/3
Step-by-step explanation:
2. Use the equation y2-y1/x2-x1. In this line, I took the points (-4,-5) and (-1,5). Plug this into the equation to get 5--5/-1--4. Simplify this to get 5+5/-1+4. Simplify this to get 10/3. Therefore, the slope is 10/3
4. The equation is y=mx+b where m is the slope and b is the y-intercept. This means that the equation will be 8/3x-5.

Solve the following:
A man borrowed a Rs 5000 from a money lender for 5 years at the rate of 8% per annum. How much interest did he pay for 5 years? Also find the amount.
Answer:
Interest = Rs 2000
Amount = Rs 7000
Step-by-step explanation:
Amount = Principal + Interest
Given
Principal = Rs 5000
Interest= PRT/100
Interest = 5000*8*5/100
Interest = 50*40
Interest = Rs 2000
Amount after 5years = 5000 + 2000
Amount after 5years = Rs 7000

Jasmine had an average daily balance of $1,608.24 for the last billing cycle, which had 31 days. If her credit cards charges an APR of 22.99%, what would her finance charges be for the last billing cycle?
Answer:
Finance per billing cycle = $ 30.91
Step-by-step explanation:
First, we will calculate the APR for 1 day:
APR per day = (22.99%/year)(1 year/12 month)(1 month/31 days)
APR per day = 0.062 % / day
Now, we will calculate the finance per day:
Finance per day = (Daily Balance)(APR per day) = ($ 1608.24)(0.062 %/day)
Finance per day = $0.99/day
Now, we will calculate the finance for one billing cycle:
Finance per billing cycle = (Finance per day)(31 days) = ($ 0.99/ day)(31 days)
Finance per billing cycle = $ 30.91
