I need help with number 24. It says is it possible that Lauren answered more questions correctly on the second math test than Antoine did? Explain.
Answers
Calculating the probability of getting more than 75% of answers right with random guessing is unlikely to yield a count higher than 24 correct answers. Therefore it is improbable for Lauren to have answered more questions correctly than Antoine. However, without specific data on Lauren's and Antoine's test results, we cannot say with absolute certainty.
Explanation:To ascertain if Lauren could have answered more questions correctly on her second math test than Antoine, we need to understand the concept of probability. In this case, we want to find P(x > 24) which means we want to find out if getting more than 75 percent (or more than 24 correct answers) out of 32 questions is possible. That is, did Lauren score more than 24? However, the probability of getting more than 75 percent of the 32 questions correct when randomly guessing is practically zero. Mathematically, we express this as P(x > 24) = 0.
This suggests obtaining a score higher than 24 is very difficult, and therefore it's unlikely that Lauren answered more questions correctly than Antoine, especially if answering was based on random guessing. However, without specifics about Lauren's or Antoine's performance, we can't say definitively.

The Manager has concluded that 2 out of 25 light bulbs are faulty.The table he created represents the ratio of bulbs checked and which ones were found faulty.
A way that he could verify that the table is correct is by simplifying each ratio. If each of them turn out to 2:25, then the conclusion is correct.
The best answer that matches this is answer choice "C.)" as it also defines our method of verifying the table's validity (just the order of the ratio is reversed, and that's fine as long as the variables are matching as well). We can further prove that this answer is correct by making ratios of our table and simplifying them;
100:8; divide both sides by 4.
25:2
500:40; divide both sides by 20.
25:2
2,000:160; divide both sides by 80.
25:2
This ratio is always the simplified answer.
Your answer is: "C.)"

________________________________________________
Explanation:
_______________________________________________
Given: " 24 − 18y " ; Factor this expression ;
We can factor out a "6" ; since "6" is the GCF (greatest common factor) among the 2 (TWO) terms: "24" and "18y" ;
________________________________________________
Note: With practice, the "GFC = 6" can be identified upon inspection; but here is a complete explanation:
________________________________________________
Given the 2 (TWO) terms; "24" and "18y"; we know that only one term has a "y", so we are looking for the GCF of "24" and 18:
________________________________________________
18: 1, 2, 3, 6, 9, 18 .
24: 1, 2, 3, 4, 6, 8, 12, 24 .
We look at the factors of EACH number—and can tell that "6" is the GCF among both "18" and "24" (and thus, among both "18y and 24" ).
So, to factor the expression: "24 − 18y" ;
We factor out a "6" ; to get our answer; which is:
______________________________________________
" 6(4 − 3y) " .

A telecommunication company has 7 satellites, two of which are sending a week signal. If two are picked at random without replacement, find the probability that both are sending a week signal
Answers
Hence, the probability that both are sending a weak signal is [tex]\frac{1}{21}.[/tex]
What is probability?
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.
The probability of an event is a number between [tex]0[/tex] and [tex]1[/tex], where, roughly speaking, [tex]0[/tex] indicates the impossibility of the event and [tex]1[/tex] indicates certainty.
Since, [tex]\frac{2}{7}[/tex] is the probability that the first satellite sends a weak signal.
And leaves six, and one is sending a weak signal.
So, the probability that the second also sends a weak signal it has the probability [tex]\frac{1}{6}[/tex].
By Combining these and we get
[tex]\frac{2}{7}[/tex]×[tex]\frac{1}{6}[/tex] = [tex]\frac{1}{21}[/tex] .
Hence, the probability that both are sending a weak signal is [tex]\frac{1}{21}.[/tex]

( C = 5b+200 ) this equation is used to find C, the total cost for painting a quantity of books (b) . What equation is equivanlent when solved for B in terms of C
Answers
To solve the equation C = 5b + 200 for b in terms of C, subtract 200 from both sides of the equation and then divide both sides by 5.
Explanation:To solve the equation C = 5b + 200 for b in terms of C, we need to isolate the variable b. First, subtract 200 from both sides of the equation:
C - 200 = 5b
Next, divide both sides of the equation by 5:
b = (C - 200)/5
So, the equivalent equation when solved for b in terms of C is b = (C - 200)/5.

The hot summer fair is coming to town! Admission to the fair costs 12.99 and each ride costs 1.75. You have 35 to spend at the fair including admission.
Answers
The correct answer is:
12 rides
Explanation:
You have $35 to spend. Taking away the admission price, $12.99, we have
35-12.99 = $22.01 left.
Each ride costs $1.75. This means you can ride
22.01/1.75 = 12.577 or 12 rides. (This does not round up, as you would not have enough money to ride 13 rides.)
which transformation of the function f(x) is the rigid motion: 2f(x)+3, f(x/2)+1, 2f(x/2), or f(x-1/2)+3
Answers
The transformation of a function may lead to the rigid motion based on what type of transformation you applied in it. Thus, option D is correct.
We need to check the transformation that is the rigid motion for the function f(x).
Now, the different transformation is given below:
2f(x)+3, f(x/2)+1, 2f(x/2), f(x-1/2)+3Let us take the transformations of the function from the top to the bottom.
(1) In the first transformation, we changed our function f(x) to 2f(x)+3.
When we used multiplication of division operations towards any functions then it will change the amplitude of the function, and hence it is not a rigid motion.
(2) In the second transformation, we changed our function f(x) to f(x/2)+1.
When we used multiplication of division operations towards any functions then it will change the amplitude of the function, and hence it is not a rigid motion.
(3) In the third transformation, we changed our function f(x) to 2f(x/2).
When we used multiplication of division operations towards any functions then it will change the amplitude of the function, and hence it is not a rigid motion.
(4) In the fourth transformation, we changed our function f(x) to f(x-1/2)+3.
When we used multiplication of division operations towards any functions then it will change the amplitude of the function, and when we use addition or subtraction towards any function then the amplitude remains constant. Hence, it is a rigid motion.
Thus, option D is correct.

A photographer uses a light meter to measure the intensity of light from a flash bulb.

Answers
The approximate instantaneous rate of change in the intensity of light at exactly 3m from the flash bulb is -20/27 lux per meter.
Explanation:The photographer uses a light meter to measure the intensity of light from a flash bulb. The intensity of the flash bulb, I, in lux, can be represented by the function I(d) = 10/d^2, where d is the distance from the light in meters.
To determine the approximate instantaneous rate of change in the intensity of light at exactly 3m from the flash bulb, we need to find the derivative of the intensity function with respect to d. Taking the derivative, we get dI/dd = -20/d^3.
Substituting d = 3 into the derivative, we get dI/dd = -20/3^3 = -20/27.
Therefore, the approximate instantaneous rate of change in the intensity of light is -20/27 lux per meter at exactly 3m from the flash bulb.
The approximate instantaneous rate of change in the intensity of light at exactly 3m from the flash bulb is approximately -0.741 lux/m.
Explanation:To determine the instantaneous rate of change in the intensity of light at exactly 3m from the flash bulb, we need to find the derivative of the intensity function with respect to distance.
The intensity function is given as I(d) = 10/d^2, where d is the distance from the light in meters. To find the derivative, we can use the power rule for differentiation.
Taking the derivative of the intensity function gives us: dI/d(d) = -20/d^3.
At exactly 3 meters, the instantaneous rate of change in the intensity of light can be calculated by substituting d=3 into the derivative equation: dI/d(d) = -20/3^3 = -20/27. Therefore, the approximate instantaneous rate of change in the intensity of light at exactly 3m from the flash bulb is approximately -0.741 lux/m.
