By visual inspection determine the best-fitting regression model for the data plot below
Answer:
Exponential
Step-by-step explanation:
By visual inspection the graph generated by the points plotted is an exponential graph as the graph curves upward. The graph is also continous and differs from either a decreasing or increasing Linear graph, which shows a straight best of fit pattern. Hence, the graph most closely represents an exponential graph from visual examination.
The best-fitting regression model for the considered data plot is given by:
Option A: Exponential.
What is fitting of curve for a data plot?When the data shows some trend, either linear (making a line), or non-linear (a predictable curve), we fit a mathematical curve on that data set, as a representative of the pattern in that data set, to predict the output based on the inputs.
The considered plot is not forming a straight line(so no linear fitting), but we can see that a smooth curve can be fitted in the considered data. Since the exponential functions' graph approximately goes the same way (for positive exponent, and increasing value of output).
Thus, the best-fitting regression model for the considered data plot is given by: Option A: Exponential.

Given any triangle ABC labeled as shown the law of sines states that:
what time did he reach ???
Answer: 2050hrs
Step-by-step explanation:
If he is going 72 km/hr and he traveled 504 km we can calculate how long he took to go by dividing the distance he went by distance per hour. That will give us the amount of hours that he took to get there. That would be [tex]\frac{504}{72}[/tex]. [tex]\frac{504}{72}=7[/tex] so it took him 7 hours to get there. 7 hours after 1350 is 2050 assuming we are using the 24 hour clock notation.

12. The length and width of a rectangle are in the ratio 7:3. If the perimeter is 62cm calculate: (1) the width (ii) the length of a diagonal to the nearest centimetre. (iii) the area of the rectangle.
Answer:
Step-by-step explanation:
Length = 7x
Width = 3x
Perimeter = 2L + 2W
Part A
2*7x + 2*3x = 62
14x + 6x = 62
20x = 62
x = 62/20
x = 3.1
Length = 3.1 * 7 21.7
Width = 3.1 *3 9.3
Width = 9.3
Part B
Use the Pythagorean Theorem
diagonal squared = 21.7^2 + 9.3^2
diagonal^2 = 557.38
sqrt(diagonal^2) = sqrt(557.38)
diagonal = 23.61
To the nearest cm is 24
Part C
Area = L*W
Area = 21.7 * 9.3
Area = 201.8

The Marked price of a jacket at a dealer's shop is 2400. The dealer allows a discount of 15% to the retailer. As the company's policies the marked price of the retailer should be the same as the dealer's marked price. What SP should the retailer fix for the jacket? What would its final price be if 10% VAT is imposed? What would be the actual gain of retailer?
Ans
2280,2502,240
Answer:
2400
2640
360
Step-by-step explanation:
I am not sure the description is totally clear.
my assumptions are (based on my interpretations of the text) :
the retailer buys from the dealer with 15% discount.
but the retailer has to sell the jacket for the same price as the dealer.
so, both mark the sale price as 2400.
if the customer buys from the retailer, the retailer makes 15% profit (the discount he got from the dealer).
15% = 2400 × 15/100 = 24 × 15 = 360
the retailer makes this profit no matter what other fees or taxes are added.
if the customer buys from the dealer, the dealer makes these 15% and some more (we don't know how much) profit.
now, the final price is to include also 10% VAT
100% = 2400
1% = 2400 / 100 = 24
10% = 24 × 10 = 240
so,
final price = SP + VAT = 2400 + 240 = 2640

Use △DEF, shown below, to answer the question that follows: What is the value of x rounded to the nearest hundredth? Type the numeric answer only in the box below
Answer:
x=63.25
Step-by-step explanation:
Hi there!
We're given ΔDEF with m<E=90°, m<D=49°, DE=55, and EF=x
we need to find the value of x
Let's use trigonometry to do it
Since we are given the measures of the 2 legs (the sides that make up the 90° angle), let's use tangent, specifically tan(49), since we are given the measure of that angle
Recall that tangent is [tex]\frac{opposite}{adjacent}[/tex]
in reference to m<D (the angle that is 49°), the opposite side is EF (x) and the adjacent side is DE (55)
so tan(49)=[tex]\frac{x}{55}[/tex]
plug tan(49) into your calculator; remember to have the calculator on degree mode
tan(49)≈1.15 (rounded to the nearest hundredth)
so that means:
1.15=[tex]\frac{x}{55}[/tex]
multiply both sides by 55 to clear the fraction
63.25=x

Sadia works at a theatre selling popcorn. Large boxes of popcorn sell
for $5.00 and small boxes of popcorn sell for $3.00. During her shift
last night, she sold 60 boxes of popcorn. Her receipts totalled $260,
not including taxes. Determine the number of large and small
popcorn boxes she sold last night.
Answer:
its 55 not 60
Step-by-step explanation:
just divide 260 by 5 and 3
The required number of large and small popcorn boxes sold are 40 and 20 respectively.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
Here,
Let the number of the large box be x and the small box is y.
According to the question,
5x + 3y = 260 - - - - - - -(1)
x + y = 60
x = 60 - y - - - - - - - - (2)
Put the value of equation, (2) in equation 1
5 (60 - y) + 3y = 260
300 - 5y + 3y = 260
2y = 40
y = 20
Now,
x = 60 - 20
x = 40
Thus, the required number of large and small popcorn boxes sold are 40 and 20 respectively.

According to the Question,
Given,Andre is running in an 80-meter hurdle race. There are 8 equally-spaced hurdles on the race track. The first hurdle is 12 meters from the start line and the last hurdle is 15.5 meters from the finish line.Thus, the distance from the first hurdle to eighth hurdles is 80-(12+15.5) = 52.5m

Mandy travels more miles.
We determine this by multiplying the distance from home by the number of trips.
For Mandy, she lives 10 miles away from school, and takes 9 trips. 9 times 10 is 90 miles.
For Matt, he lives 8 miles away from school, and takes 11 trips. 11 times 8 is 88 miles.
Many travels 2 more miles in total than Matt.

The difference is a2 - a1 = 31 - 24 = 7
n = 500
a500 = a1 + (500 - 1) * 7

The system of equations can be solved using linear combination to eliminate one of the variables. 2x − y = −4 → 10x − 5y = −20 3x + 5y = 59 → 3x + 5y = 59 13x = 39 Which equation can replace 3x + 5y = 59 in the original system and still produce the same solution?
Answer:
[tex]13x=39[/tex]
Step-by-step explanation:
Given
[tex]2x - y = -4 \to 10x - 5y =-20[/tex]
[tex]3x +5y =59 \to 3x +5y = 59[/tex]
Required
What can replace [tex]3x +5y = 59[/tex] ?
We have:
[tex]10x - 5y =-20[/tex]
and
[tex]3x +5y = 59[/tex]
Add up both equations:
[tex]10x +3x-5y+5y=-20+59[/tex]
[tex]10x +3x=39[/tex]
[tex]13x=39[/tex]
Since [tex]13x=39[/tex] is a result of [tex]10x - 5y =-20[/tex] and [tex]3x +5y = 59[/tex],
[tex]13x=39[/tex] can replace [tex]10x +3x=39[/tex]
