Answer:
C. Predicts someone's blood alcohol level from the number of whiskey drinks they consumed.
Step-by-step explanation:
In Statistics, classification problems are differentiated from estimation problems because classification problems typically requires that the output attribute be categorical while estimation problems require that the output attribute is numerical. In an estimation problem, the output variable has a continuous or real value, such as predicting the size, area, weight, age or even the cost of an item.
A Classification problem work with the concept of creating a succinct model such as decision trees, Naive Bayes, random forest, logistic regression, etc, which is capable of predicting from the attribute (observed) variables given; values of the dependent attribute, which is always categorical.
In order to predict a dichotomous variable from a given data set comprising of continuous or dichotomous variables, a logistic regression can be used.
Mathematically, it is given by the expression;
Logistic regression [tex] y [/tex] with [tex] x_{1} [/tex], [tex] x_{2} [/tex]........[tex] x_{n} [/tex]
Where;
y represents the dichotomous dependent variable.
[tex] x_{1} [/tex], [tex] x_{2} [/tex]........[tex] x_{n} [/tex] represents the predictable variables, which are categorical in nature such as alive or dead, win or lose, sick or healthy, pass or fail, etc.
Hence, a regression would be appropriate for predicting someone's blood alcohol level from the number of whiskey drinks they consumed.

Lacey filled a measuring cup with 1/2 of a cup of vegetable oil. Then she poured 1/3 of a cup of the oil into a frying pan. How much oil is left in the measuring cup?
Answer:
1/6 of a cup
Step-by-step explanation:
You're trying to figure out what 1/3 subtract 1/2 is, right?
Well first, convert both of them so they both have the same denominator.
Common Denominator = 6
So, 1/3 is 2/6 and 1/2 is 3/6 and 2/6 plus 3/6 is 5/6. Well, what's left in the cup? 6/6 subtract 5/6 is 1/6
Hope that helps!

Answer:
51cm is the answer.
Step-by-step explanation:
a = ?
b = 68cm
c = 85cm
According to the Pythagoras theorem,
a² + b² = c²
a² + 68² = 85²
a² + 4624 = 7225
a² = 7225 - 4624
a² = 2601
a = 51cm
∴ the porch is 51cm tall.

A ball is dropped from the top of a building that is 250 feet tall. The
height h of the ball in feet after t seconds is modeled by the function h =
- 16t2 + 250. How long will it take for the ball to reach a height of 75
feet? Round to the nearest tenth.
hi
-16t²+250 = 75
-16t² = 75 -250
-16t² = -175
t² = -175 /-16
t² = 175/16
Here there si two solutions : t = [tex]\sqrt{175/16}[/tex] and t = - [tex]\sqrt{175/16}[/tex]
However, as time cannot rewind, we will keep only positive solution
So t = [tex]\sqrt{175/16}[/tex]
in seconds it will be : 3.3 seconds

Answer:
1. Yes
2. They could change the 60° angle into a different one.
Step-by-step explanation:
1. Two triangles are the same if they share two side lengths with the same angle between them.
2. Since the triangles are equal if they share two side lengths with the same angle between them, if they changed the angle between 3 and 5, it'd no longer be the same triangle.
Which point is directly above (4, -1)?
(-4,1)
(4,1)
(4,-1)
Answer:
(4,1)
Step-by-step explanation:
1: Different x value (bad: 8 units to the left of original point), different y value (good: on higher horizontal line), d
2: Same x value (good: same vertical line), different/higher y value (good: 2 units above original point).
3: Same x value (good: same vertical line), same y value (bad: same horizontal line, didn’t move higher or lower).
I hope this makes sense lol
What is the statement written as an equation
Answer:
3x+2=17 is the equation and x=5
Step-by-step explanation:
Answer:
Equation: 2 + 3x = 17
x = 5
Step-by-step explanation:
2 more than means: 2 +
3 times a number means: 3x
Is 17 means: = 17
Combine them all together:
2 + 3x = 17
Find x:
2 + 3x = 17
3x = 17 - 2
3x = 15
x = 5
Which is NOT true?
+
A.
5 + 14 = 20.- 1

Answer:
D
Step-by-step explanation:
No BS and show all of your work please and you must use the 1% or 10% method which I don’t know what that is LOL
Answers:
38% of 15 = 5.7
29% of 75 = 21.75
4% of 220 = 8.8
No idea what the 1% or 10% method is either. But these answers would be better then to leave the questions blank.

a rectangle with an area of 4/7m^2 is dilated by a scale factor of 7 what is the area of the dilated rectangle enter your answer in the box do not leave answer as a fraction
9514 1404 393
Answer:
28 m²
Step-by-step explanation:
The area of the dilated figure is the original area multiplied by the square of the dilation factor.
A' = 7²×A
A' = 49×(4/7 m²) = 28 m²
The area of the dilated rectangle is 28 m².

A model rocket is launched with an initial upward velocity of 62/ms. The rocket's height h (in meters) after t seconds is given by the following.
h=62t-5t^2
Find all values of t for which the rocket's height is 29 meters.
Round your answer(s) to the nearest hundredth.
9514 1404 393
Answer:
t = 0.49, 11.91
Step-by-step explanation:
A graphing calculator can show you the answers quickly. The times are 0.49 seconds and 11.91 seconds.
__
We can write the equation as ...
h = 29
62t -5t^2 = 29 . . . . . substitute for h
-5(t^2 -12.4t) = 29
-5(t^2 -12.4t +6.2^2) = 29 -5(6.2^2) . . . . complete the square
-5(t -6.2)^2 = -163.2 . . . . . simplify
t -6.2 = ±√(-163.2/-5) = ±√32.64 . . . . divide by -5, take the square root
t = 6.2 ±5.71
t = 0.49, 11.91
The rocket has a height of 29 meters at t=0.49 seconds and t=11.91 seconds.

Answer:
[tex]\pi[/tex] or 3.1
Step-by-step explanation:
The total area of the circle is [tex]3^2\pi[/tex]. The central angle of the shaded region is 40 degrees so we have to multiply [tex]3^2\pi[/tex] by [tex]\frac{40}{360}[/tex] or [tex]\frac{1}{9}[/tex]. 3 squared is 9 so 9[tex]\pi[/tex] times [tex]\frac{1}{9}[/tex] is just equal to [tex]\pi[/tex]. [tex]\pi[/tex]=3.14159265... rounded to the nearest tenth is 3.1
