A scientist is investigating whether percent concentration can be used to predict density in apple juice. A scientist selected a random sample of 12 apple juice varieties and recorded the density, in pounds per cubic inch, and the percent concentration of each apple juice variety. The scientist wants to estimate the mean change in the density, in pounds per cubic inch, for each increase of 1 percent concentration of apple juice. Assuming the conditions for inference have been met, which of the following inference procedures is most appropriate for this investigation?
a. A linear regression t-interval for slope.
b. A matched-pairs t-interval for a mean difference.
c. A two-sample t-interval for a difference between means.
d. A one-sample t-test for means.
e. A two-sample z-interval for a difference between proportions
Answer:
The most appropriate inference procedure for the investigation is;
a. A linear regression t-interval for the slope
Step-by-step explanation:
Given that the slope of an horizontal line is zero, we have that there is no change in the y (dependent) variable when there is a change in the x-variable, therefore, it is important to find the true relationship between the two variables, 'x', and 'y'
The confidence interval of the slope is calculated and analyzed to determine if it excludes or includes, 0, such that, if the confidence interval exclude 0, then, it is unlikely that the slope is 0, therefore, there the relationship between the variables, 'x', and 'y' is significant
Therefore, a linear regression t-interval for the slope is most appropriate.

A person is looking from a car to the top of a building. The angle of elevation to the top of the building from the car is 32°. The building is 200 feet away. How tall is the building? Round to the nearest foot.
Answer:
132.2 ft
Step-by-step explanation:
This is a right angle problem where 32 is the angle and 200 feet is the leg unederneath. To solve for the height we use tangent since we have the adjacent side and we are solving for the opposite side.
Steps:
1. tan32 = x/200
2. (tan32)200=x
3. x=132.2 ft

Answer:

Step-by-step explanation:
2. When you take a taxi, the driver charges an initial fee
when you start a ride and then an additional charge for
every mile driven in the cab. If the total fare for a cab
ride is 3.5m + 2.5 after riding for m miles, what does the
2.5 represent? Explain (use appropriate math
vocabulary in your explanation).
Answer:
The
3
mile cab ride includes a basic charge as well as the cost for the distance covered.
For a
6
mile trip, the cost is
$
4.80
which means that :
The cost of
3
miles is
$
4.80
−
$
3.00
=
$
1.80
Therefore the cost for
1

÷

=
$
0.60
The basic fee for hiring the cab is
$
3.00
−

=

So the total cost,

for a trip of

Check:
If

If

45/20 = x/18
Cross multiply
20x = 45 * 18

x = 810/20
x = 40.5
Hence the value of x is 40.5
Samir and Christian had a total of 360 marbles Samir lost 28 marbles while Christian brought 18 more marbles both of them had an equal number of marbles in the end how many marbles did Samir have at the beginning
Step-by-step explanation:
Marbles altogether = 360
Marbles Samir Lost = 28
360 - 28 = 332
Marbles Christian bought 18
332 + 18 = 350
Marbles both had in the end = 350 ÷ 2 = 175
Marbles Samir have at the beginning = 175 + 28 = 203
Answer = 203
To compare two products such as colas, a random sample is selected to taste two types of colas (A and B). Each selected subject tastes both colas and selects his/her preferred cola. What sample size would be needed to ensure that the margin of error in the brand preference is less than 5 percentage points in more than 95% of experiments
Answer: The sample size would be needed = 385
Step-by-step explanation:
Let p be the prior population proportion.
Margin of error = E
When not estimate of p is given , the formula to calculate the minimum sample size n = [tex]0.25(\dfrac{z^*}{E})^2[/tex] , where z* = critical value for given confidence interval.
Here z* for 95% confidence level is 1.96.
E=5%=0.05
Then [tex]n=0.25(\dfrac{1.96}{0.05})^2\approx385[/tex]
Hence, the sample size would be needed = 385

Answer:
49 units
Step-by-step explanation:
The units on the other 3 sides (this is excluding the slanted portion ofc.)
would add up to 36.
Now you only left with doing the slanted portion of the shape. We must use pythagorean theorem to solve for the slanted portion. The longer leg, 12 units long. Just count from the point (18,4) and then stop at (18,16) it stops on the same line as the point (13,16)
Leg B=12
Leg A=5
Leg C=?
[tex]a^2+b^2=c^2[/tex]
25+144=196
Then square root 169. You will get 13
36+13=49

Solve: (x −6)−(4.5−x )= −1.5
PLZ HELP
Answer:
x=9/2 Hope this helps!
Step-by-step explanation:
Let's solve your equation step-by-step.
x−6−(4.5−x)=−1.5
Step 1: Simplify both sides of the equation.
x−6−(4.5−x)=−1.5
x−6+−1(4.5−x)=−1.5(Distribute the Negative Sign)
x+−6+(−1)(4.5)+−1(−x)=−1.5
x+−6+−4.5+x=−1.5
(x+x)+(−6+−4.5)=−1.5(Combine Like Terms)
2x+−10.5=−1.5
2x−10.5=−1.5
Step 2: Add 10.5 to both sides.
2x−10.5+10.5=−1.5+10.5
2x=9
Step 3: Divide both sides by 2.
2x/2=9/2
x=9/2
Answer is 9/2.

A cone has a diameter of 18 units and height of 8 units. What is its volume?
A. 721 cubic units
B. 21617 Cubic units
C. 64817 cubic units
D.8641 cubic units
Answer: I hope this helps!
Step-by-step explanation:
The volume of cone having diameter 18 units and height 8 units is 678.85 cubic units which is nearest to 648.17 cubic units which is option C.
What is volume?Volume is basically amount of substance a container can hold in its capacity. Volume of cone is 1/3 *π[tex]R^{2}H[/tex] in which R is the radius and H is height of cone.
How to find volume?We know that volume of cone is 1/3 *π*[tex]R^{2} H[/tex]
We have to put the value of radius and height in the formula to get the value of volume of cone.
Radius=diameter/2
=18/2
=9 units.
Volume=1/3 * 3.14*9*9*8
=2034.72/3
=678.24 cubic units
Nearest option is 648.17 cubic units.
Hence the volume of the cone is 648.17 units.
