Amit solved the equation 5/12 = -x/420 for x using the steps shown below. What is Amit's error?
5/12 = -x/420
5/12(420) = -x/420(420)
x = 175
A: Amit should have multiplied both sides by 5/12
B: Amit should have multiplied both sides by 12/5
C: The product of 5/12 and 420 is not equal to 175
D: The product of 5/12 and -420 should have been the value of x
Answer:
D: The product of 5/12 and -420 should have been the value of x

Write an equation of the line passing through the given points.
(3,-25) and (-3,5)
y=
Answer:
y = -5x -10
Step-by-step explanation:
This is the slope-intercept form:
[tex]y-y_{1} = m(x -x_{1})[/tex]
First, we look for the slope. The slope is found by using the equation:
[tex]m = \frac{y_{2}-y_{1} }{x_{2} -x_{1}}[/tex]
[tex]m = \frac{5 - (-25)}{-3 - 3} = \frac{30}{-6} = -5[/tex]
m = -5.
Now, given the two points, our y₁ is -25, and our x₁ is 3. Therefore, we substitute these values into the equation, and get:
y - (-25) = -5(x - 3)
y + 25 = -5(x - 3)
y + 25 = -5x + 15
y = -5x + 15 -25
y = -5x -10
Answer:
the answer to the problem is y= -5x - 10

Answer:
a)18.8
Step-by-step explanation:
Basically, you have to add all the numbers from the data set (188) then divide them by 10 and that equals 18.8
The second part you have to add 32 to 188 ( which equals 210) and that by 11 which equals 20
For parallelogram ABCD, find m<1
Answer:
b
Step-by-step explanation:
the answer is
the angel m<1= 36°
The measure of angle m<1= 36°.
What is a parallelogram?That quadrilateral in which opposite sides are parallel is called a parallelogram.
Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.
WE are given that angle CAD = 36 degree
So, we know that parallelogram has parallel opposite sides.
Thus according to alternate interior angle we can say that;
angle CAD = angle m<1 = 36
therefore, the measure of angle m<1= 36°

An urn contains b black balls and r red balls. One of the balls is drawn at random, but when it is put back in the urn c additional balls of the same color are put in with it. Now suppose that we draw another ball.
Required:
Show that the probability that the first ball drawn was black given that the second ball drawn was red is b/(b r c).
Answer:
Please see the explanation below for proof
Step-by-step explanation:
Probability of choosing black ball from the bag
[tex]\frac{b}{b+r}[/tex]
Probability of choosing red ball from the bag
[tex]\frac{r}{b+r}[/tex]
After the addition of c balls of correspondent color –
P (R2/B1) [tex]= \frac{r}{(r+b+c)}[/tex]
P (R2/B2) [tex]=\frac{r+c}{(r+b+c)}[/tex]
B1 and B2 are mutually exclusive event
P (B1/R2) = [tex]\frac{\frac{r}{(r+b+c)} *\frac{b}{b+r}}{\frac{r}{(r+b+c)}*\frac{b}{b+r} + \frac{r+c}{(r+b+c)}* \frac{b}{b+r}}[/tex]
P (B1/R2) [tex]=\frac{b}{(r+b+c)}[/tex]

The residents of a city voted on whether to raise property taxes. The ratio of yes votes to no votes was 3 to 2. If there were 1833 yes votes, what was the total
number of votes?
Answer: 1,222
Step-by-step explanation:
I would set this up as a fraction
3/2=1833/x
I would divide 1833 by 3 to see what the multiple is that would be used to find the equivalent fraction. Then multiply that number by 2 to solve for x.
Another option is to cross multiply
3x=2(1833)
1833*2=3666
Divide 3x by 3 to get x alone
Divide 3666 by 3 to get answer

In the year 2054 the government estimates that out of every 1,000,100 citizens 1,000,000 will remain law-abiding, and 100 will eventually commit a crime. The government is deciding whether to rely on the clairvoyant Precogs to stop the criminals before they commit the crime. If a person is going to commit a crime, the Precogs identify that person correctly 99.999% of the time (in other words, the Precogs fail to predict crime only in 0.001% of the cases). If a person is not going to commit a crime, the Precogs identify that person as law-abiding 99.99% of the times (in other words, the Precogs convict innocent people only in 0.01% of the cases). What is the probability that a person flagged as a future criminal by the Precogs will actually commit a crime
Answer:
0.9091 = 90.91% probability that a person flagged as a future criminal by the Precogs will actually commit a crime
Step-by-step explanation:
Bayes Theorem:
Two events, A and B.
[tex]P(B|A) = \frac{P(B)*P(A|B)}{P(A)}[/tex]
In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.
In this question:
Event A: Flagged as future criminal
Event B: Commits a crime.
In the year 2054 the government estimates that out of every 1,000,100 citizens 1,000,000 will remain law-abiding, and 100 will eventually commit a crime.
This means that [tex]P(B) = \frac{100}{1000100} = 0.00009999[/tex]
If a person is going to commit a crime, the Precogs identify that person correctly 99.999% of the time
This means that [tex]P(A|B) = 0.99999[/tex]
Probability of being identified as a criminal:
0.99999 out of 0.00009999(identified and commits crime).
(1-0.99999) out of (1-0.00009999) (identifed and does not commits crime). So
[tex]P(A) = 0.99999*0.00009999 + (1-0.99999)*(1-0.00009999) = 0.000109988[/tex]
What is the probability that a person flagged as a future criminal by the Precogs will actually commit a crime
[tex]P(B|A) = \frac{P(B)*P(A|B)}{P(A)} = \frac{0.00009999*0.99999}{0.000109988} = 0.9091[/tex]
0.9091 = 90.91% probability that a person flagged as a future criminal by the Precogs will actually commit a crime

Give your answer as a mixed number.
Answer:
4.125 in decimal form and 4 1/8 in simplified fraction form
Step-by-step explanation:
The value of multiplication of an improper fraction 3/8 and a whole number 11 as a mixed number is 4 1/8.
To calculate 3/8 × 11 as a mixed number, we can follow these steps:
Step - 1:
Multiply the whole number by the numerator of the fraction:
11 × 3 = 33
Step - 2:
Divide the result by the denominator of the fraction:
33 ÷ 8 = 4 with a remainder of 1
Step - 3:
The whole number part of the mixed number is the quotient from the division:
The whole number part is 4.
Step - 4:
The fractional part of the mixed number is the remainder divided by the original denominator:
The fractional part is 1/8.
Therefore, the answer to 3/8 × 11 as a mixed number is 4 1/8.
