A. -26 B.-9 C. -1 D. 10
Answers
The value of g(f(-3)) would be -9 which is the correct answer would be an option (B).
What exactly is a function?
A function is defined as a mathematical phrase that specifies a connection between two variables in algebra.
We have been given the functions below as
f(x) = 3x + 7 and g(x) = 2x - 5
We have to determine the value of g(f(-3))
Substitute the value of f(x) = 3x + 7 in the g(x) = 2x - 5 to get g(f(x))
⇒ g(f(x)) = 2(3x + 7) - 5
Apply the distributive property of multiplication,
⇒ g(f(x)) = 6x + 14 - 5
⇒ g(f(x)) = 6x + 9
Substitute the value of x = -3 in the g(x) = 2x - 5 to get g(f(-3))
⇒ g(f(-3)) = 6(-3) + 9
⇒ g(f(-3)) = -18 + 9
⇒ g(f(-3)) = -9
Therefore, the value of g(f(-3)) would be -9.

Answer:
41. s = semiperimeter
s = (a + b + c) /2
s = (120+170+250) /2
s = 270m
d is the correct option.
42. b is the correct option.
43. P = a + b + c
P = 120+170+250
P = 540m
a is the correct option.
44. A = √s((s-a)(s-b)(s-c))
=√270((270-120)(270-170)(270-250))
=9000m²
d is the correct option.

let’s create another system of equation.
Let a = 4
and Let b = -3
First equation
=> Let’s pick any numbers to be used. Let’s have number 5
=> 5a + 5b
=> 5 (4) + 5 (-3)
=> 20 + (-15)
negative and positive is equals to negative
=> 20 – 15
=> 5 (this the first value of our equation, let this be the value of X)
Second
=> Pick another number, Let’s have 6
=> 6a + 6b
=> 6 (4) + 6 (-3)
=> 24 + (-18)
=> 24 – 18
=> 6 (this is the value of our second equation, let this value be Y)
Now, we have (A, B) = (4, -3) and (X, Y) = (5,6)
Answer:
A linear equation can be written in several forms. "Standard Form" is #ax+by=c# where #a#, #b# and #c# are constants (numbers).
We want to make two equations that
(i) have this form,
(ii) do not have all the same solutions (the equations are not equivalent), and
(iii) #(4, -3)# is a solution to both.
#ax+by=c#. We want #a#, #b# and #c# so that
#a(4)+b(-3)=c# (This will make (i) and (iii) true.)

2x2 + 14xy -36y2 = 2x2 + (2B-4)xy -4By2
since the coefficient of y2 is equal so
-4B = -36
B = 9

Complete question is;
An ordinary deck of playing cards has 52 cards. There are four suits
-spades, hearts, diamonds, and clubs
-with 13 cards in each suit.
Spades and clubs are black; hearts and diamonds are red. One of these cards is selected at random. Let A denote the event that a red card is chosen.
Find the probability that a red card is chosen, and express your answer in probability notation.
Answer:
P(A) = 0.5
Step-by-step explanation:
We are told that the ordinary deck of playing cards has 52 cards.
Now, there are four suits
-spades, hearts, diamonds, and clubs
-with 13 cards in each suit.
Now, in a standard set of playing cards, there are 13 black spades and 13 black clubs as well as 13 red hearts and 13 red diamonds
Thus;
Number of red cards = 13 + 13
Thus;
Number of red cards = 26
Since, A denotes the event that red card is chosen.
This means that probability of choosing a red card is;
P(A) = number of red cards/total number in a deck of cards
P(A) = 26/52
P(A) = 0.5

Answer:
B) For each participant in the study, the difference between his/her GPA and the mean GPA.
Step-by-step explanation:
Residuals in a regression model represent the differences between the observed values (in this case, student GPAs) and the predicted values (the mean GPA predicted by the model). So, option B is the correct description of what you will see when you print the residuals.
