Step-by-step explanation:
Linear regression requires sufficient data points for analysis, which are not provided, making it impossible to calculate an estimated price for a 1700 ft2 home without additional information.
Explanation:To estimate a fair price for a 1700 ft2 home using linear regression, we would require more data points with corresponding house prices to create a regression model. Since we're not provided with sufficient data in the question, and there's no explicitly provided regression equation or coefficients, it's not possible to accurately calculate the estimated price for a home of a given square footage using linear regression. However, if we had such data, we would typically plot square footage on the x-axis and house price on the y-axis, calculate the slope and intercept coefficients of the regression line, and then use the regression equation y = mx + b (where y is the estimated house price, m is the slope, x is the square footage, and b is the y-intercept) to predict the price of the house with given square footage

The diameter of a golf ball is about 4 centimeters. Which of these is the closest to the volume of a golf ball?
16.75 cm^3
33.51 cm^3
100.53 cm^3
268.08cm^3
The volume is approximately 33.51 [tex]cm^3[/tex], option B.
The question asks us to determine the closest volume to a golf ball with a diameter of approximately 4 centimeters. To find the volume of a sphere (which is the shape of a golf ball), we use the formula:
V = (4/3)π[tex]r^3[/tex],
where r is the radius of the sphere. Since the diameter of the golf ball is given as 4 cm, the radius would be half of that, which is 2 cm. Plugging in the radius into the formula, we have:
[tex]V = (4/3)\pi(2 cm)^3 = (4/3)\pi(8 cm^3) = (32/3)\pi cm^3,[/tex]
Now, we calculate the value using the approximation π = 3.14:
V = (32/3) × 3.14 [tex]cm^3[/tex] = 33.51 [tex]cm^3[/tex] (approximately).
Therefore, the volume that is closest to the actual volume of the golf ball is 33.51 [tex]cm^3[/tex], option B.

An equation for the depreciation of a car is given by y = A(1-r)^twhere y = current value of the car, A = original cost, r = rate of
depreciation, and t = time, in years. The value of a car is half what it originally cost. The rate of depreciation is 10%. Approximately
how old is the car?
Answer: The car is 6.6 years old.
Step-by-step explanation:
Hi, to answer this question we have to replace the values in the equation given:
Y = 1/2 (half the value)
A = 1 (total value)
r =10% = 0.10 (decimal form)
Replacing:
y = A(1-r)^t
1/2 = 1 (1-0.10)^t
Solving for t:
(1/2)/1 = 0.9^t
1/2 = 0.9^t
log 1/2 = log 0.9^t
log 1/2 = (t) log 0.9
(log 1/2)/ log 0.9 = t
6.57 =t

The measure of XYZ is 45. The length of radius YZ is 6 inches. What is the area of sector XYZ?
(Use 3.14 for I.)
Answer:
area of a sector = 14.13 yards²
Step-by-step explanation:
XYZ is a sector of a circle. The radius YZ is 6 inches .The angle of the sector is given as 45°. The area of the sector can be solved as follows.
area of a sector = ∅/360 × πr²
where
r = radius
∅ = center angle
r = 6 inches
∅ = 45°
area of a sector = 45/360 × 3.14 × 6²
area of a sector = 45/360 × 3.14 × 36
area of a sector = 45/360 × 113.04
area of sector = 1/8 × 113.04
area of a sector = 14.13 yards²

Question: Solve it using the proportion method.
The Royal Fruit Company produces two types of fruit drinks. The first type is 60% pure fruit juice, and the second type is 85% pure fruit juice. The company is
attempting to produce a fruit drink that contains 70% pure fruit juice. How many pints of each of the two existing types of drink must be used to make 160
pints of a mixture that is 70% pure fruit juice?
Answer: 96 pints of the first fruit drink (60% pure fruit juice) and 64 pints of the second fruit drink (85% pure fruit juice).
Step-by-step explanation:
This question is a system of equations. First, we will define our variables:
Let x= number of pints of the first fruit drink (60% pure fruit juice), and then y = the number of pints of the second fruit drink(85% pure fruit juice).
We know that there are 160 total pints of the mixture. Therefore,
x + y = 160 .......... equation i
We are also aware that 70% of those 160 pints will be pure fruit juice, and they will come from either x or y.
For x pints of the first juice, there is
0.6x of pure fruit juice and for y pints of first juice, there is 0.85y of pure fruit juice. Therefore, we will have:
0.6x + 0.85y = 160 × 0.7
0.6x + 0.85y = 112
Multiply through by 100 to remove decimal. This will be:
60x + 85y = 11200 ........... equation ii
Combine both equations
x + y = 160 .......... i
60x + 85y = 11200 ........ ii
Multiply equation i by 60
Multiply equation ii by 1
60x + 60y = 9600 ........ iii
60x + 85y = 11200 ......... iv
Subtract iv from iii
-25y = -1600
y = 1600/25
y = 64
Since x + y = 160
x = 160 - 64
x = 96
Therefore , we will need 96 pints of the first fruit drink (60% pure fruit juice) and 64 pints of the second fruit drink (85% pure fruit juice).

a triangular section of a farm is enclosed by fences that are 2 meters, 6 meters, and 7 meters long, estimate the area of the section
Final answer:
To estimate the area of a triangular section with sides 2 meters, 6 meters, and 7 meters, you can use Heron's formula. The semi-perimeter is 7.5 meters. The estimated area of the triangle is approximately 5.56 square meters.
Explanation:
To estimate the area of a triangular section of a farm enclosed by fences that are 2 meters, 6 meters, and 7 meters long, we can use Heron's formula. First, we calculate the semi-perimeter (s) of the triangle:
s = (a + b + c) / 2s = (2 + 6 + 7) / 2s = 15 / 2s = 7.5 metersNow, we use Heron's formula to find the area (A):
A = √(s(s-a)(s-b)(s-c))A = √(7.5(7.5 - 2)(7.5 - 6)(7.5 - 7))A = √(7.5 * 5.5 * 1.5 * 0.5)A = √(30.9375)A ≈ 5.56 square metersTherefore, the estimated area of the triangular section of the farm is approximately 5.56 square meters.

A golfer hits a ball from a starting elevation of 7 feet with a velocity of 70 feet per second down to a green
with an elevation of -2 feet. The number of seconds t it takes the ball to hit the green can be represented
by the equation - 16t2 + 70t +7=-2. How long does it take the ball to land on the green?
It takes the ball ___
seconds to land on the green.
Answer:
[tex]t \approx 4.501\,s[/tex]
Step-by-step explanation:
The second-grade equation must be rearragend into its standard form:
[tex]-16\cdot t^{2} + 70\cdot t + 9 = 0[/tex]
Roots can be found with the help of the General Equation for Second-Order Polynomial:
[tex]t = \frac{-70\pm \sqrt{70^{2}-4\cdot (-16)\cdot (9)}}{2\cdot (-16)}[/tex]
[tex]t = 2.188 \pm 2.313[/tex]
[tex]t_{1} \approx 4.501\,s[/tex]
[tex]t_{2} \approx -0.125\,s[/tex]
Only the first root offers a reasonable solution.
[tex]t \approx 4.501\,s[/tex]
which set of side lengths form a right triangle?
A. 8 cm, 17 cm, 14 cm
B. 50 in., 48 in., 14 in.
C. 53 m, 48 m, 24 m
D. 3 ft, 6 ft, 5 ft
Answer:
I think the answer is B.
Answer:
b.) [tex]50,48,14[/tex]
Step-by-step explanation:
To find if a set of lengths makes a right triangle, use the Pythagorean theorem:
[tex]a^2+b^2=c^2[/tex]
If a and b squared equal c squared, then the set makes a right triangle. C (the hypotenuse) is the largest number of the set because the hypotenuse is always the largest side in a right triangle.
Use the options:
a.) insert values:
[tex]8^2+14^2=17^2\\64+196=289\\260\neq 289[/tex]
260 does not equal 289, so a is wrong.
b.) insert values:
[tex]14^2+48^2=50^2\\196+2304=2500\\2500=2500[/tex]
2,500 equals 2,500, so b is correct.
Finito.
In an assembly line, 56 out of 60 randomly selected parts have no faults. Predict the number of parts that will have no faults in a similar batch of 12,000 parts.
We have been given that in an assembly line, 56 out of 60 randomly selected parts have no faults. We are asked to predict the number of parts that will have no faults in a similar batch of 12,000 parts.
We will use proportions to solve our given problem.
[tex]\frac{\text{Not faulty parts}}{\text{Total parts}}=\frac{56}{60}[/tex]
[tex]\frac{\text{Not faulty parts}}{12,000}=\frac{56}{60}[/tex]
[tex]\frac{\text{Not faulty parts}}{12,000}\times 12,000=\frac{56}{60}\times 12,000[/tex]
[tex]\text{Not faulty parts}=56\times 200[/tex]
[tex]\text{Not faulty parts}=11,200[/tex]
Therefore, approximately [tex]11,200[/tex] parts will have no faults in a similar batch of 12,000 parts.

Shwetha comes to the swimming pool once every 12 days. Vinnie comes once every 4 days and Olga comes once every 10 days. Last Monday all of them were in the pool. In how many days all of them will meet at the swimming pool again? What day of the week will it be?
Answer:
60 days, Friday
Step-by-step explanation:
This problem is solved using concept of LCM.
LCM is the least number which is the common multiple of given set of different number.
To find the LCM we method of prime factors, the steps are given below
get all the all the prime factor of the given set of numberselect all the prime factors as many times they occur in given set of numbermultiply together the numbers selected together to get LCM________________________________________________
Given
frequency of visiting swimming pool by Shwetha = once in 12 days
factors of 12 = 2 * 2 * 3
frequency of visiting swimming pool by Vinnie = once in 4 days
factors of 2 = 2 * 2
frequency of visiting swimming pool by Olga = once in 10 days
factors of 10 = 2 * 5
minimum no of days after which they will be visiting together will be least common multiple of number of days after which they visit swimming pool individually.
Selecting the prime numbers with their highest occurrence
we have 2, 2, 3 ,5
multiplying them together we have
2 * 2 * 3* 5 = 60
therefore 60 is the LCM of 12, 4, 10
it means that Shwetha, Vinnie and Olga will visit swimming pool together once in 60 days
It is given that they visited on Monday and now they will visit after 60 days again.
since in one week there are seven days, every eighth day will be monday
so we divide 60 days by 7 to see how many cycles of monday has passed.
60/7 = 8 4/7
It suggest that 8 weeks has passed and they will meet on 4 days after Monday which will be Friday.
Thus they will meet meet at the swimming pool again in 60 days.
It will be Friday.
Answer:
60 days, friday

The circumference of a circle is 24π ft. What is the area, in square feet? Express your answer in terms of
π
π.
Answer:
[tex]144\pi[/tex]
Step-by-step explanation:
Circumference = [tex]\pi d[/tex]
Diameter = [tex]2r[/tex]
Area of a circle = [tex]\pi r^2[/tex]
From our first equation, we can find our value for our diameter:
We do this by dividing [tex]24 \pi[/tex] by [tex]\pi[/tex] to get 24.
[tex]c=\pi d[/tex]
[tex]d=\frac{c}{\pi } = \frac{24\pi }{\pi } =24[/tex]
Using our second equation, we can find out the value for our radius:
[tex]d=2r[/tex]
[tex]r=\frac{d}{2} =\frac{24}{2} =12[/tex]
Now we have a value for our radius, we can use our third equation to find out our area:
[tex]A=\pi 12 ^2 = 144 \pi[/tex]
Given that:
The circumference of a circle is 24π ft.To Find:
What is the area, in square feet?We know that:
Circumference of a circle = 2πRArea of a circle = πR²Where,
Radius is denoted as R.Finding the radius of the circle:
Circumference of a circle = 24π
⟶ 2πR = 24π
⟶ 2πR = 2π × 12
Cancelling 2π.
⟶ R = 12
∴ Radius of the circle = 12 ft.
Finding the area of the circle:
⟶ Area = πR²
⟶ Area = π(12)²
⟶ Area = π × 12 × 12
⟶ Area = π × 144
⟶ Area = 144π
Hence,
Area of the circle is 144π square feet.
