Error Analysis! Answer both parts of the question.
Kaitlyn solved the equation 5y = 15 and found the answer to be y = 75.
(Problem down below in file)
Part A: In a complete sentence or two, explain what Kaitlyn's error was. What did she do wrong?
Part B: What is the correct answer? Show your work and/or explain your reasoning.
Answers
Answer:
Kaitlin's answer is wrong because she is supposed to by dividing. When trying to get rid of a number from a variable you have to divide the number by itself and whatever you do to one side you have to do to the other side
so you would do 5/5 - cancels out
15/5=3
y=3
Step-by-step explanation:
have a great day :D
Answer:
y = 3Explanation (Part A):
She was supposed to divide five both sides. However, she divided one side by five and multiplied five on the other side, which makes her answer incorrect. She got confused that if any side is divided by a number, the other side must be divided by that same number.Solution (Part B):
5y = 15=> 5y/5 = 15/5=> y = 3The correct answer must be 'y = 3'.

two supplementary angles have a ratio of 4:5 what is the measure of the larger angle?
Answers
Answer:
100°
Step-by-step explanation:
Supplementary means the sum of the angles is 180°
so we add 4+5 = 9
180/9 = 20

The expressions are equivalent to the given expression are (6²)⁸ and (6⁻⁴)⁻⁴. Therefore, options C and F are the correct answers.
What is an equivalent expression?Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.
The given expression is 6¹⁶.
Here, 6¹⁶=(6⁴)⁴
6¹⁶=(6²)⁸
6¹⁶=(6⁸)²
6¹⁶=(6⁻⁴)⁻⁴

Let x and y be two positive numbers whose sum is 175 and (x+3)(y+4) is a maximum
Answers
Answer:
Step-by-step explanation:
x+y = 175
y = 175 - x
f(x) = (x+3)(y+4)
= x(175-x) + 3(175-x) + 4x + 12
= 175x - x² + 525 - 3x + 4x + 12
= -x² +176x + 537
f'(x) = -2x + 176
maximum when x = 88
y = 175-x = 87

Answer:
y = 3x -6
Step-by-step explanation:
The three turning points of the terms divide the graph into 4 pieces. We can consider what functions apply in each piece.
x < -2
All terms are negated:
y = (3 -x) -(x +2) -(5 -x) = -x -4
-2 < x < 3
The first and last terms are negated:
y = (3 -x) +(x +2) +(x -5) = x
3 < x < 5
The last term is negated:
y = (x -3) +(x +2) +(x -5) = 3x -6
5 < x
No terms are negated:
y = (x -3) + (x +2) -(x -5) = x +4
_____
In the region of interest, the equation simplifies to y = 3x -6.

Step-by-step explanation:
Let the recommended amount is x.
ATQ,
A grilled chicken salad at a popular fast food restaurant contains 650 mg of sodium which is 27% of recommended daily amount.
Mathematically,
[tex]27\%\ of\ x=650 \\\\\dfrac{27}{100}x=650\\\\x=\dfrac{650\times 100}{227}\\\\x=286.34\ mg[/tex]

The hypotenuse has length 4sqrt(3)
The ratio of the lengths of its sides is:
short leg : long leg : hypotenuse
1 : sqrt(3) : 2
The short leg measures half the hypotenuse.
short leg = (1/2)4sqrt(3) = 2sqrt(3)
The long leg measures the short leg times sqrt(3)
long leg = 2sqrt(3) * sqrt(3)
long leg = 6

Answer:

Step-by-step explanation:
Given
[tex]P(D) = 0.26[/tex]
[tex]P(P) = 0.50[/tex]
[tex]P(D\ and\ P) = 0.13[/tex]
The question illustrates conditional probability and it is represented as:
P(D|P)

So, we have:
[tex]P(D|P) = \frac{0.13}{0.26}[/tex]
