To investigate the relationship between the selling price of a house, y , in dollars, and the size of the house x, in square feet, a local builder collected data on a random sample of 120 houses from a certain region. Assume that the conditions for inference for the slope of a regression line are met. The resulting 95 percent confidence interval for the population slope of the regression line relating price and size is given by (62,99). The local builder claims that the selling price of houses from the region increases by $104 for every extra square foot of space in the house. Which of the following best describes the conclusion that can be reached about this claim based on the confidence interval?
a. The claim is supported by the interval, since the interval does not contain the value 0.
b. The claim is supported by the interval, since all values in the interval are positive.
Ñ. The claim is supported by the interval, since the interval does not contain the value 104.
d. The claim is not supported by the interval, since the interval does not contain the value 0.
e. The claim is not supported by the interval, E since the interval does not contain the value 104.
Answers
Answer:
E) The claim is not supported by the interval, since the interval does not contain the value 104.
Step-by-step explanation:
A claim that the selling price increases by $104 for each square foot increase in space is not supported by the interval. The interval represents plausible values for the slope of the regression line, and the interval does not include the value 104.

Group of answer choices
A. 49x2 − 28x + 16
B. 9a2 − 30a + 25
C. 25b2 − 45b − 81
D. 16x2 − 24x − 9
Answers
Answer:
The answer is B. 9a2-30a+25
Step-by-step explanation:
First of all, the second sign is going to be +, so you can toss out C and D without checking.
Then you take the square root of the two ends, multiply them, multiply by two and see if it matches.
sqrt(49) * sqrt(16) = 7 * 4 = 28
28 * 2 = 56
56 <> 28
So toss A.
sqrt(9) * sqrt(25) = 3 * 5 = 15
15 * 2 = 30
So the answer is B
(3a - 5)^2 = 9a^2 - 30a + 25

Find the coordinates of the point (x, y)
shown on the unit circle.
X=?
Y=?
Answers
Answer:
the coordinates of the point of x and y is -1÷ 2 and -√3÷ 2
Step-by-step explanation:
The computation of the coordinates of the point is shown below:
The angle is
= 4π ÷ 3
The radius is 1 unit
Now
x = rcos[tex]\theta[/tex], and y = rsin[tex]\theta[/tex]
Now
x = 1cos(4π ÷ 3) = -1÷ 2
y = 1sin(4π ÷ 3) = -√3÷ 2
hence, the corordinates of the point of x and y is -1÷ 2 and -√3÷ 2
Answer: x= -1/2 y= -root3/2

A competitive cliff diver jumps into
water 81 feet below. The distance d that the diver falls
in t seconds is given by the equation d = 16t^2. How
long does it take the diver to hit the water?
Answers
Answer:
2.25 seconds
Step-by-step explanation
[tex]d=16t^{2}[/tex]
[tex]d=81 feet\\t=?[/tex]
Because you know what distance equals you can plug it into the equation
[tex]81=16t^{2}[/tex]
From there you can solve by dividing the 16 over and then square rooting.
[tex]\frac{81}{16}=t^{2}[/tex]
[tex]5.0625=t^{2}[/tex]
You take the square-root to get rid of [tex]t^{2}[/tex]
[tex]\sqrt{5.0625} =\sqrt{t}^{2}[/tex]
[tex]t=2.25[/tex]

The American Heart Association is about to conduct an anti-smoking campaign and wants to know the fraction of Americans over 33 who smoke. Step 1 of 2: Suppose a sample of 1267 Americans over 33 is drawn. Of these people, 913 don't smoke. Using the data, estimate the proportion of Americans over 33 who smoke. Enter your answer as a fraction or a decimal number rounded to three decimal places.
Answers
Answer:
The estimate for the proportion of Americans over 33 who smoke is 0.28.
Step-by-step explanation:
Proportion of Americans over 33 who smoke.
Number who smoke divided by the size of the sample.
In this question:
Sample of 1267.
913 don't smoke, so 1267 - 913 = 354 smoke. Then
[tex]p = \frac{354}{1267} = 0.28[/tex]
The estimate for the proportion of Americans over 33 who smoke is 0.28.

Jenny has overdrawn her bank account by $48.38. She makes a withdrawal of $10.25 and then makes a deposit of $60. What is the amount of money in Jenny's account after with withdrawal and deposit?
Answers
Over drawn means negative.
So she is at -43.38 then withdraws ( takes out) 10.25
Now her account is at -43.38-10.25 = -53.63
She than adds 60
Her final amount is -53.63 + 60 = $6.37
Answer:
-48.38-10.25= -58.63
-58.63 + 60= 1. 37

Step-by-step explanation:
The computation of the value of the x is given below:
Given that
x = 2y - 1...........(1)
2x = 3y + 2.................(2)
Put the equation 1 in equation 2
i.e.

What is an arithmetic progression?The sequence in which every next number is the addition of the constant quantity in the series is termed as the arithmetic progression.
A number series is a number-based sequence. In the number series questions, we must identify the rules that lead to the formation of a number series.
Given that the series is 9, 15, 21, ..., The 35th term of the sequence will be calculated as,
Sn = n /2 [ ( 2a + ( n - 1 ) d]
Sn = 35 / 2 [ ( 2 x 9 + ( 35 - 1 ) 6)]
Sn = 35 /2 { 18 + ( 34 x 6 ) ]
Sn = 35 / 2 x 222
Sn = 3885
Hence, the sum of the 35 terms of the series will be 3885.

Answers
Answer:

Step-by-step explanation:
Split the firgue into shapes you know
rectangle and Trapezoid
A = bh
A = 10×6
A = 60
A = 1/2h(b+b)
A = 1/2×12(10+20)
A = 6(30)
A = 180
180 + 60 = 240
240
Answer:
420 cm²
Step-by-step explanation:
Area of composite shapes
To calculate the area of a composite shape you must divide the shape into rectangles, triangles, or other shapes you can find the area of and then add the areas back together. You may have to calculate missing lengths before finding the area of some of the shapes. Other composite shapes may have cut-out sections.Solve
To find the composite area of two or more shapes, simply find the area of each shape and add them together.
So,
18 cm × 20 cm = 360
10 cm × 6 cm = 60
Now, add the results together
360 + 60 = 420
Therefore, the area of the composite figure is 420 cm²
