Suppose that you have trained a logistic regression classifier, and it outputs on a new example x a prediction hθ(x) = 0.7. This means (check all that apply):
Our estimate for P(y=0|x;θ) is 0.7.
Our estimate for P(y=1|x;θ) is 0.7.
Our estimate for P(y=0|x;θ) is 0.3.
Our estimate for P(y=1|x;θ) is 0.3.
Answers
The prediction hθ(x) = 0.7 means that the probability of the example having a value of y=1 is 0.7 (or 70%). Our estimate for P(y=0|x;θ) is 0.3. and Our estimate for P(y=1|x;θ) is 0.7.
The prediction hθ(x) = 0.7 means that the probability of the example having a value of y=1 is 0.7 (or 70%). This means that the probability of the example having a value of y=0 is 0.3 (or 30%). Therefore, our estimate for P(y=0|x;θ) is 0.3 and our estimate for P(y=1|x;θ) is 0.7.
The logistic regression classifier is a supervised learning algorithm used for binary classification. It is used to estimate the probability of an example belonging to one of two classes, typically 0 or 1. The output of the classifier, hθ(x), is a value between 0 and 1, which is interpreted as the probability of the example belonging to class 1. In the given case, the output of the classifier is hθ(x) = 0.7, which implies that the probability of the example belonging to class 1 is 0.7 (or 70%) and the probability of the example belonging to class 0 is 0.3 (or 30%). Thus, our estimate for P(y=0|x;θ) is 0.3 and our estimate for P(y=1|x;θ) is 0.7.

If y varies directly with x and y = 21 when x = 3, find y if x = 5.
First, find the direct variation equation. y = [ ? ] x
Answers
when y = 21, x = 3
when y and x vary directly, that means there is something that you multipy x that gets you to y.
to solve for this number, you divide y by x.
21= 3=7
this means to go from x to y, you multiply x by 7.
7x = y
we can use this to solve for x when y = 42
7x = 42
divide both sides by 7
X = 6

By using the promotional deal the kids saved 20 dollars.
What is a promotional deal?Simply put, a promotion is a discounted product or service that you already have available on your website or that you want to offer. We re-promote it, and the consumer can view it and be directed to the Merchant's website, location, or phone number – no online transaction is necessary.
A promotion is frequently a recurring event that happens weekly or daily to draw more people to a particular day. It doesn't necessitate an online transaction but does include some sort of discount or added value. A promotion may be accessible online for several days, weeks, months, or even years.
When you buy 5 $12 admission tickets you get a free $3 cotton candy and a free $2 soda
A group of 20 buys each $12 admission tickets, i.e
20/5
= 4 promotional deal
All together they are eligible for 4 promotion deal.
They get 4 $3 cotton candy and 4 $2 soda
= $12 + $8
= $20
Half of them want cotton candy = 20/2
= 10
¼ of them want soda = 20/4
= 5
10 × $3 cotton candy
= $30
5 × $2 soda
= $10
Total $40
Dollars the save = $40 - $20
= $20

The solution to the system of equations.
Given:
4x + 2y = -6
-3x – 2y = 7
To solve the given system using the elimination method, we will follow the steps below:
Step 1
Eliminate y by adding the first and second equation.
\(\lparen4x-3x)+\left(2y-2y\right)=-6+7\)\(x=1\)Step 2
Substitute x=1 into the first equation.
\(4\left(1\right)+2y=-6\)Step 3
Subtract 4 from both-side of the equation.
\(\begin{gathered} 2y=-6-4 \\ \\ 2y=-10 \end{gathered}\)Step 4

A.
Volume of Pyramid : ⅓*base area * height
here,
Base area = area of rectangle=length*breadth =10*8=80in²
Now
Height can be calculated by using Pythagorous theorem
height =\(\sqrt{(slant\: height)^2-(\frac{breadth}{2})^2}\)
height =\(\sqrt{14^2-(\frac{8}{2})^2}=\sqrt{196-16}=\sqrt{180}=13.42 in\)
height =13.4 in
Now
Volume of pyramid = ⅓*base area *height
Volume of Pyramid=⅓*80*13.42
Volume of Pyramid=357.8 in³
B.
Volume of cone = ⅓*area of base* height
Here
slant height=24 yd
height =?
diameter=14yd
radius =14/2=7 yd
Let's find the height:
By using the Pythagorous theorem,
slight height²=radius²+height²
substituting value
25²=7²+height²
height²=25²-7²
height =\(\sqrt{576}\)=24 yd
Now
Area of Base= πr²=π*7²=153.94 yd²
Now
Volume = ⅓*area of base*height =⅓*153.94*24=1231.5 yd³
So,
Volume of cone is 1231.52 yd³.

This is a ssa situation, no triangle is possible.
Step-by-step explanation:
"SSA" means "Side, Side, Angle".
In an SSA triangle, we are given two sides and an angle that is not the angle between the given sides.
In triangle ABC:
A, B and C are the interior angles.a, b and c are the sides opposite the corresponding interior angles.Given:
m∠A = 44°side a = 12.6 cmside b = 19 cmThe angle that is between the sides a and b is angle C.
Therefore, as angle A is not the angle between the given sides, ΔABC is an SSA triangle.
Law of Sines
\(\sf \dfrac{\sin A}{a}=\dfrac{\sin B}{b}=\dfrac{\sin C}{c}\)
(where A, B and C are the angles and a, b and c are the sides opposite the angles)
To determine if any triangles are possible, substitute the given values into the Law of Sines to find angle B:
\(\implies \sf \dfrac{\sin 44^{\circ}}{12.6}=\dfrac{\sin B}{19}\)
\(\implies \sf \sin B=\dfrac{19\sin 44^{\circ}}{12.6}\)
\(\implies \sf \sin B=1.0475007...\)
As -1 ≤ sin B ≤ 1, there is no solution for angle B.
Therefore, although this is an SSA situation, no triangle is possible.

We have to find the minimal size for a pool and deck constructed as in the application, with the deck extending an additional 10 meters on each side of the pool and a further 5 meters along the corresponding sides of the pool. The pool's area is 1800 square meters.
We know that,
Area of the Total space = (l+10)(b+20)
Here,
b=1800/l
l= 30
So,
b=60
Area of the total space is (30+10)(60+20) = 40×80 = 3200 m²
The minimum area of deck = 3200-1800 = 1400 m²

2,500x2+637.5=5,637.5
Answer:
$5,612.16
Step-by-step explanation:
Part 1) Account I earns 4% annual simple interest.
we know that
The simple interest formula is equal to A = P (1+rt)
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have:
t = 3 years
P = $2,500
r = 4% = 4/100 = 0.04
substitute in the formula above
A = 2,500 (1 + 0.04 * 3)
A = 2,500 (1.12)
A = $2,800
Part 2) Account II earns 4% interest compounded annually.
we know that
The compound interest formula is equal to: A = P (1 + r/n)nt
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
t = 3 years
P = $2,500
r = 4% = 4/100 = 0.04
n = 1
substitute in the formula above
A = 2,500 * (1 + 0.04/1)3
A = 2,500 * (1.04)3
A = $2,812.16
Part 3) What is the sum of the balances of Account I and Account II at the end of 3 years?
Sum the two final investment:
$2,800 + $2,812.16 = $5,612.16

Jane is having difficulty deciding whether to put her savings in the Mystic Bank or in the Four Rivers Bank. Mystic offers a 12% rate compounded quarterly, and Four Rivers offers 14% compounded semiannually. Jane has $40,000 to invest and expects to withdraw the money at the end of five years. The better deal is:
Multiple Choice
Four Rivers because she will earn about $6,442 more.
Four Rivers because she will earn about $6,523 more.
Four Rivers because she will earn about $4,000 more.
Four Rivers because she will earn about $20,000 more.
Answers
Answer:
The answer is option (C). Four Rivers Bank
Explanation:
a). The total amount Jane will receive after 5 years after investing $40,000 in the Mystic Bank can be expressed as follows;
A = P (1 + r/n) (nt)
where;
A = the future value of the initial investment
P = initial investment amount/principal amount
r = the annual interest rate
n = the number of times that interest is compounded per unit t
t = the time the money is invested for
In our case;
P=$40,000
r=12/100=0.12
n=interest is compounded quarterly which is four times a year=4
t=5 years
Replacing values in the formula;
A=40,000(1+0.12/4)^(4×5)
A=40,000(1+0.03)^20
A=40,000×1.806
A=72,244.45
The total amount Jane will receive after 5 years if she chooses to invest with the Mystic Bank is $72,244.45
b). The total amount Jane will receive after 5 years after investing $40,000 in the Four Rivers Bank can be expressed as follows;
A = P (1 + r/n) (nt)
where;
P=$40,000
r=14/100=0.14
n=interest is compounded semiannually which is two times a year=2
t=5 years
Replacing values in the formula;
A=40,000(1+0.14/2)^(2×5)
A=40,000(1+0.07)^10
A=40,000×1.967
A=78,686.05
The total amount Jane will receive after 5 years if she chooses to invest with the Four Rivers Bank is $78,686.05
c). The best deal would be to invest with Four Rivers Bank for 5 years since the total amount Jane will receive after 5 years will be $78,686.05 which is greater than $72,244.45, which is the total amount she will receive if she chooses to invest with Mystic Bank
