Find the equation for the line of best fit using the two points that are close to the line of best fit (2,70) and (4.5, 90)
Given:
Two points that are close to the line of best fit are (2,70) and (4.5, 90).
To find:
Th equation of best fit line using the given two points.
Solution:
We know that, if a line passes through the two points, then the equation of line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
Two points (2,70) and (4.5, 90) are close to the best fit line.
Consider the two points (2,70) and (4.5, 90). So, the equation of line is
[tex]y-70=\dfrac{90-70}{4.5-2}(x-2)[/tex]
[tex]y-70=\dfrac{20}{2.5}(x-2)[/tex]
[tex]y-70=8(x-2)[/tex]
[tex]y-70=8x-16[/tex]
Adding 70 on both sides, we get
[tex]y=8x-16+70[/tex]
[tex]y=8x+54[/tex]
Therefore, the equation of best fit line is [tex]y=8x+54[/tex].

What is the prime
factorization of 200
using exponents?
The prime factorization of 200 with exponent is 23*52.
Factoring involves finding two numbers that, when multiplied together, yield the original number. But often we can factor these two factors into smaller numbers, and even find the factors of these smaller numbers. Prime factorization divides a number into a series of prime numbers and allows them all to be multiplied to equal the original number.
First, find the prime factorization of 200.
(200=2*100) (200=2*100)
(200=2*2*50) (200=2*2*50)
(200 = 2 * 2 * 2 * 25) (200 = 2 * 2 * 2 * 25)
(200 = 2 * 2 * 2 * 5 * 5) (200 = 2 * 2 * 2 * 5 * 5)
Then group similar factors together.
(2∗2∗2)∗(5∗5)(2∗2∗2)∗(5∗5)
Hence, we write the prime factorization list, but we represent the grouped factors by writing the base factors and adding exponents of the number of times they are repeated.
23 * 53

The time T, necessary to make an enlargement of a photo negative,
varies directly to the area, A, of the enlargement. If 36 seconds are
required to make a 2-by-3 enlargement, find the time required for a
5-by-11 enlargement.
Answer:
330 seconds (5 minutes, 30 seconds)
Step-by-step explanation:
You want the time required for a 5×11 enlargement when a 2×3 enlargement takes 36 seconds, and time is proportional to area.
AreaThe area of a rectangle is the product of length and width.
area of smaller enlargement: 2×3 = 6
area of larger enlargement: 5×11 = 55
TimeThe time is proportional to the area, so when the area increases by a factor of 55/6, so does the time:
(36 seconds) × (55/6) = 330 seconds
The time required for a 5×11 enlargement is 330 seconds.
According to Investment Digest ("Diversification and the Risk/Reward Relationship", Winter 1994, 1-3), the mean of the annual return for common stocks from 1926 to 1992 was 16.5%, and the standard deviation of the annual return was 19%.
What is the probability that the stock returns are less than 18.5%
The probability that perhaps the stock returns will be less than 18.5% is 0.542.
The normal distribution is:In most cases where the possible study population is large, a normal distribution is chosen. Apart from its easier application than that of other distribution methods, this is the primary reason for its efficiency.
According to the given information:Let X be the annual return on common stocks throughout 1926 to 1992.
The average of X is 16.5%.
X has a standard deviation of 19%.
Assume X is regularly distributed.
X∼N(μ,σ)
∼N(16.5,19)
The likelihood that stock returns seem to be less than 18.5% is calculated using the Z-table, as shown below.
P(X < 18.5) = [tex]P\left(\frac{X-\mu}{\sigma} < \frac{18.5-16.5}{19}\right)[/tex]
= P(Z < 0.1053)
= 0.542
The probability that perhaps the stock returns will be less than 18.5% is 0.542.

Find the sale price of the item. Round to two decimal places if necessary.
Original price: $84.00
Markdown: 32%
The sale price is
Answer:
[tex]Sales\ Price = \$57.12[/tex]
Step-by-step explanation:
Given
[tex]Price = \$84.00[/tex]
[tex]Markdown = 32\%[/tex]
Required
Determine the sales price
First, we calculate the markdown price.
This is calculated by multiplying the original price the markdown percentage
[tex]Markdown\ Price = \$84.00 * 32\%[/tex]
Convert % to decimal
[tex]Markdown\ Price = \$84.00 * 0.32[/tex]
[tex]Markdown Price = \$26.88[/tex]
The sales price is then calculated as:
[tex]Sales\ Price = \$84.00 - \$26.88[/tex]
[tex]Sales\ Price = \$57.12[/tex]
Hence, the sales price after markdown is $57.12

In a different tug of war, one team pulls with a force of 50 newtons at an angle of 30 degrees from the positive x-axis, and a second team pulls with a force of 25 newtons at an angle of 250 degrees. Use a scale drawing to determine the total force and angle applied to the central ring. How did they get the following answer?34.8 N at 2.5 degrees from the positive x-axis
Answer:
34.8 N at 2.5 degrees from the positive x-axis
Step-by-step explanation:
From the given information:
The force F makes an angle A with the positive x axis can be expressed in terms horizontal and vertical components.
[tex]F_x = F cos A\\\\ F_y = Fsin A[/tex]
Given that
[tex]F_1 = 50 \ N[/tex]
[tex]\theta_1 = 30 ^0 \ \ \ (x-axis)[/tex]
[tex]F_{1x} = F_1 \times Cos A_1[/tex]
= 50 × cos 30
= 43.3 N
[tex]F_{1y} = F_1 \times Sin \ A_1[/tex]
= 50 × sin 30
= 25 N
Similarly;
[tex]F_2 = 25 \ N[/tex]
[tex]\theta_2 = 250 ^0 \ \ \ ( x-axis)[/tex]
[tex]F_{2x} = F_2 \times cos \ A_2[/tex]
= 25 × cos 250
= - 8.55 N
[tex]F_{2y} = F_2 \times A_2[/tex]
= 25 × sin 250
= -23.5 N
The total net force;
[tex]F_{net} = F_{(net)}_x + F_{(net)}_y[/tex]
[tex]F_{net} = (F_{1x} + F_{2x} ) i + (F_{1y} + F_{2y} )j[/tex]
[tex]F_{net} = (43.3 - 8.55) i + (25-23.5 ) j[/tex]
[tex]F_{net} =34.75 i + 1.5 j[/tex]
[tex]|F_{net} | = \sqrt{F_{net}_x^2 + F_{net}_y^2}[/tex]
[tex]|F_{net} | = \sqrt{34.75^2 + 1.5^2}[/tex]
[tex]|F_{net} | = 34.8 \ N[/tex]
Finally, the direction of the angle for the net force is:
[tex]tan \theta = \dfrac{F_{net_y}}{F_{net_x}}[/tex]
[tex]\theta = tan^{-1} \Big (\dfrac{F_{net_y}}{F_{net_x}} \Big)[/tex]
[tex]\theta = tan^{-1} \Big (\dfrac{1.5}{34.75}} \Big)[/tex]
[tex]\theta = tan^{-1}( 0.043165)[/tex]
[tex]\theta \simeq 2.5^0\ with \ positive \ x-axis[/tex]
You set a goal of creating a $16,000 emergency fund. You earn a salary of $40,000 per year
and decide to save 20% of your gross pay. How long will it take for you to achieve your goal?
A. 6 months
B. 1 year
C. 2 years
D. 3 years
Answer:
the answer is C. 2 years
20% of 40000 is 8000, remember that gross pay is for the end of the year not monthly
Step-by-step explanation:
It will take 2 years for you to achieve your goal. which is the correct answer would be an option (C).
Given that,
You set a goal of creating a $16,000 emergency fund. You earn a salary of $40,000 per year and decide to save 20% of your gross pay.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
Calculating 20% of the gross pay:
⇒ 20% of 40,000 = 0.20(40,000) = 8000
Since the set a goal of creating a $16,000 emergency fund.
So the required time will be :
⇒ 16,000/ 8000 = 2
Thus, it will take 2 years for you to achieve your goal.
