A class has 12 girls and 18 boys. What is the probability that a boy raises his hand and asks to go to the bathroom given a girl already left the room to go to the bathroom?
Answer:
The answer is [tex]\frac{18}{29}[/tex]
Explanation:-
Total number of students = 12 + 18 = 30
Total number of students after one girl left = 29
Number of boys = 18
Probability that a boy raises his hand and asks to go to the bathroom =
Number of boys divided by total number of students
[tex]\frac{18}{29}[/tex]
Evaluate 3xy + b if x = -4 ,y = 2 , and b = 5
Answer:
-19
Step-by-step explanation:
ok so since they give you all the variables you can substitute their values
for example instead of 3xy you can write 3*(-4)y
so that is the basic idea for this problem
after substituting, the new equation is 3*(-4)*2 +5
i plan on using order of operations, or PEMDAS
3*(-4)=(-12)
(-12)*2=(-24)
-24+5=-19
so the answer is -19
hope this helps!

Which transformations are needed to change the parent cosine function to the cosine function below?
Answer:
Answer is D
Step-by-step explanation:
Did it on Edge
The transformations are needed to change the parent cosine function to the cosine function is
Vertical stretch of 2 and horizontal compression to a period π/2 and phase shift to π unit left and vertical shift of 1 unit down.
What is Transformation?A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.
If you stretch cosine function by a factor of 2, maximum will be y = 2 and minimum will be y = -2.
and, after that you shift it 1 unit down maximum will be y = 1 and minimum will be y = -3
So, vertical stretch of 2 and horizontal compression to a period π/2.
Now, the phase shift to π unit left and vertical shift of 1 unit down.

Your classmate says that the solutions to the given inequality are x > -2. Look carefully at the work. Should your friend have reversed the inequality symbol? Explain. Then solve the inequality correctly.
Please don't send those annoying files, I'm not trying to get a virus on my laptop. Please, if you can, just write out the steps/answer(s).
Answer:
x < -2 (No, he shouldn't have reversed the inequality symbol).
Step-by-step explanation:
Given the algebraic expression;
19 - 2(1 - x) < 13
Opening up the bracket, we have;
19 + (-2*1) + (-2*-x) < 13
19 + (-2) + (2x) < 13
19 - 2 + 2x < 13
17 + 2x < 13
Rearranging the equation, we have;
2x < 13 - 17
2x < -4
Dividing both sides by 2, we have;
x < -2
Hence, your friend shouldn't have reversed the inequality symbol (sign).
Note: you should only flip the inequality symbol (sign) when you're dividing by a negative number such as -2.
For example, if we had re-arranged the equation as;
17 - 13 < -2x
4 < -2x
Dividing both sides by -2, we have;
4 > x

The difference between 25 and a number is at least 13.
Answer:
x ≤ 12
Step-by-step explanation:
The problem can be represented by the equation:
25 - x = y and y ≥ 13
So, we find that 25 - 12 = 13, which means that any number greater than 12 would result in a difference lower than 13. This sets 12 as the maximum.
2 CDs and 9 DVDs cost £69. 2 CDs and 6 DVDs cost £48. i. Form a pair of simultaneous equations to represent these two sentences ii. Solve the simultaneous equations to find the cost of 1 CD and 1 DVD.
Answer:
Cost of 1 CD = x = £3
Cost of 1 DVD = y = £7
Step-by-step explanation:
Let us represent:
Cost of 1 CD = x
Cost of 1 DVD = y
i. Form a pair of simultaneous equations to represent these two sentences
2 CDs and 9 DVDs cost £69.
2x + 9y = 69.... Equation 1
2 CDs and 6 DVDs cost £48.
2x + 6y = 48..... Equation 2
ii. Solve the simultaneous equations to find the cost of 1 CD and 1 DVD.
Combining both equations together:
2x + 9y = 69.... Equation 1
2x + 6y = 48..... Equation 2
We substract Equation 2 from Equation 1
3y = 21
y = £7
Solving for x using Equation 1
2x + 9y = 69.... Equation 1
2x + 9 × 7 = 69
2x + 63 = 69
Collect like terms
2x = 69 - 63
2x = 6
x = 6/2
x = £3
Therefore,
Cost of 1 CD = x = £3
Cost of 1 DVD = y = £7

Answer:
45.4 in is the answer :)
Step-by-step explanation:
you have to split up the shape. I decided to do it into three different parts one long at the bottom with side lengths of 8 and 4. a smaller rectangle at the top left with measurements of 5.3 and 4, (8-4=4) and the triangle which is 4 by 2.7 (8-5.3). You then find the area of each individual shape, for the rectangles you just multiply getting 32 and 21.2 for the smaller one and then find the triangle by using the formula 1/2b*h which gets you 5.4 then you add the three areas together getting 45.4 hope this helps!
Answer: 45.4 is the answer
You cucullate the base x height and then subtract the 4 in. and 5.3 in.
Consider the following system of equations.
3x + 5y = 18
6x − 5y = 20
Decide which procedures eliminate the x variable and which eliminate the y variable. Drag and drop each procedure that will eliminate one of the variables into the appropriate category.
Subtract the second equation from the first equation.
Add the first and second equations. Multiply the first equation by −2; then add the two equations.
Divide the second equation by −2; then add the two equations. Subtract the first equation from the second equation.
Multiply the first equation by 2 then add the two equations.
Eliminate x Eliminate y
Answer:
Option B
On adding the first and second equations y can be eliminated
Step-by-step explanation:
The two equations are as follows
3x + 5y = 18 -- Eq (1)
6x − 5y = 20 -- Eq (2)
Adding equation 1 and 2, we get -
3x + 6x + 5y -5y = 18
9x = 18
x = 2
y = (18-3*2)/5
y = 12/5 = 2.4

42 + z = 180
42 + z = 180
84 + z = 180
84 + z = 180
42 + 2z = 180
Answer:
84 +z= 180

NEED HELP ASAP!The maker of a cell phone screen protector would like to estimate the proportion of customers who file a warranty claim. To do so, they select a random sample of 200 customers and determine that the 96% confidence interval for the true proportion of customers who file a warranty claim to be 0.15 to 0.28. Which of the following can be accounted for by the margin of error of this interval?
response bias
nonresponse bias
sampling variation
undercoverage bias
Answer: sampling variation
Step-by-step explanation: took the quiz
The margin of error is given by the sampling variation of the proportion of customers
What is simple random sampling ( SRS )?The most accurate type of probability sampling is random sampling. Each person in a population has an equal probability of getting selected for the sample thanks to this method of sampling.
This kind of sampling is perfect for highly controlled investigations where it is unacceptable to have human bias in the selection of the sample.
Each sampling unit in a population has an equal probability of being included in the sample when using simple random sampling (SRS). As a result, each potential sample has an equal probability of being chosen.
Given data ,
Let the margin of error be represented as A
where the value of A is
The confident interval is = 96 %
And , the value of sample is of 200 customers
where the warranty claims from 0.15 to 0.28
So , the cell phone screen protector maker can be 96% confident that the interval from 0.15 to 0.28 captures true proportion of customers who file a warranty claim
Therefore , it is a sampling variation
Hence , the situation is a sample variation

Out of the 90 customers at Eva's boutique35 wore a size extra-large. What is the probability that a randomly selected customer wore a size extra-large? Write your answer as a fraction or whole number. P(extra - large) =
Answer: 7/18
Step-by-step explanation:
Number of customers at Eva's boutique = 90
Number of customers who wore a size extra-large = 35
The probability that a randomly selected customer wore a size extra-large will be:
= Number of customers who wore a size extra-large / Number of customers at Eva's boutique
= 35 / 90
= 7/18
Therefore, the probability that a randomly selected customer wore a size extra large is 7/18.
