A rectangular prism with a square base has a height of 17.2cm and a volume of 24.768cm². What is the length of its base?
Answers
The formula for the volume of a rectangular prism is:
V = lwh
where V is the volume, l is the length, w is the width, and h is the height.
We know that the height of the rectangular prism is 17.2 cm, and the volume is 24.768 cm³. We also know that the base is a square, so the length and width are the same. Let's call the length of the base x.
Then, we can write:
V = lwh
24.768 = x * x * 17.2
24.768 = 17.2x²
x² = 1.44
x = 1.2
Therefore, the length of the base of the rectangular prism is 1.2 cm.
The formula for the volume of a rectangular prism is V = lwh, where l is the length, w is the width, and h is the height.
In this problem, we know that the height is 17.2 cm, and the volume is 24.768 cm³. We also know that the base is a square, so the length and width are the same.
Therefore, we can write the equation:
24.768 = x² * 17.2
To solve for x, we can divide both sides by 17.2, and then take the square root of both sides:
x² = 24.768 / 17.2
x² = 1.44
x = sqrt(1.44)
x = 1.2
Therefore, the length of the base of the rectangular prism is 1.2 cm.

There are 9 marbles in a bag. 4 of those marbles are red,
What is the probability of picking a red marble randomly from the bag?
Answers
Answer:
4/9
Step-by-step explanation:
I think because you take the total and the amount of red you have
The probability of picking a red marble randomly from the bag will be equal to 0.44 .
It is given that there are total 9 marbles in a bag out of which 4 are red marbles.
We have to find the probability of picking a red marble randomly from the bag.
What do you mean by probability ?
Probability is the possibility or chance of an event to occur and is given by ratio of no. of favorable outcomes to total no. of outcomes.
As per the question ;
The total no. of outcomes (marbles) = 9
The no. of favorable outcomes (red marbles) = 4
We know that , probability is given by ;
Probability = No. of favorable outcomes / Total no. of outcomes
So ;
The probability of picking a red marble randomly from the bag will be equal to ;
Probability = 4 / 9
P(E) = 0.44
Thus , the probability of picking a red marble randomly from the bag will be equal to 0.44 .

Simplify. p/ab+2q/ac
Answers
Answer:
To simplify the expression p/ab+2q/ac, we need to find a common denominator for the two fractions in the denominator. The common denominator is abc.
Thus,
p/ab + 2q/ac
= p*c/abc + 2q*b/abc (multiplying the first fraction by c/c and the second fraction by b/b)
= pc/abc + 2qb/abc
= (pc + 2qb) / abc
Therefore, the simplified expression is (pc + 2qb) / abc.

Rachel is a stunt driver, and she's escaping from a building that is about to explode!
The variable d models Rachel's distance from her exit (in meters) t seconds after the cameras
began recording the stunt.
d=-38t+220
What is Rachel's speed?
meters per second
Answers
As per the concept of distance-speed-time formula, the speed of Rachel is 38 meters per second
Distance-speed-time formula
The general time formula to calculate the distance-speed-time for any task is given as
[Time = Distance ÷ Speed].
And the SI unit of time is seconds (s).
Given,
Rachel is a stunt driver, and she's escaping from a building that is about to explode! And the variable d models Rachel's distance from her exit (in meters) t seconds after the cameras began recording the stunt.
The function of d=-38t+220
Now, we have to find the speed of Rachel.
We already know that the speed is calculated as,
=> v = dx/dt
Here we have the distance is a function of time,
Now, we have to apply it one the given formula then we get,
=> v = d/dt( 38t + 220)
After the differentiation we get the value of
=> v = 38 m/s
Here the derivative of a constant (here 220) is zero.

The value of the angle x is 30 degrees
How to determine the valueTo determine the value of the variable x, we need to know the triangle sum theorem.
The triangle sum theorem is a theorem in mathematics stating that the sum total of the interior angles in a triangle is equivalent to 180 degrees.
We should also note that angle at right angle is 90 degrees
Then, we have the angles written as;
90 degrees
2x degrees
x degrees
Equate the angles , we have;
2x + x + 90 = 180
collect the like terms, we have;
2x + x = 180 - 90
add or subtract the like terms, we have;
3x = 90

the probability of an airline flight arriving on time at a certain airport is 84%, use a normal approximate to find the probability that more than 240 in a random sample of 400 commercial airline flights at the airport will arrive on time
Answers
The probability that more than 240 flights in a random sample of 400 commercial airline flights will arrive on time is approximately 1 or 100%.
To solve this problem using a normal approximation, we need to calculate the mean (μ) and standard deviation (σ) of the binomial distribution and then use the normal distribution to approximate the probability.
Given:
Probability of an airline flight arriving on time (success): p = 0.84
Number of trials (flights): n = 400
Number of flights arriving on time (successes): x > 240
First, we calculate the mean and standard deviation of the binomial distribution using the following formulas:
Mean (μ) = n * p
Standard Deviation (σ) = √(n * p * (1 - p))
μ = 400 * 0.84 = 336
σ = √(400 * 0.84 * 0.16) = √(53.76) ≈ 7.33
Now, we can use the normal distribution to find the probability that more than 240 flights will arrive on time. Since we're interested in the probability of x > 240, we will calculate the probability of x ≥ 241 and then subtract it from 1.
To use the normal distribution, we need to standardize the value of 240:
z = (x - μ) / σ
z = (240 - 336) / 7.33
z ≈ -13.13
Now, we can find the probability using the standard normal distribution table or a calculator. Since the value of z is extremely low, we can approximate it as:
P(x > 240) ≈ P(z > -13.13)
From the standard normal distribution table or calculator, we find that P(z > -13.13) is essentially 1 (close to 100%).
Therefore, the probability that more than 240 flights in a random sample of 400 commercial airline flights will arrive on time is approximately 1 or 100%.

one card is drawn from a pack of 52cards each of the 52 cards being equally likely to be drawn. what is the probability that the card drawn is a king?
Answers
The probability of drawing a king from a standard deck of 52 cards is 1/13.
In a standard deck of 52 playing cards, there are four kings: the king of hearts, the king of diamonds, the king of clubs, and the king of spades.
To find the probability of drawing a king, we need to determine the ratio of favorable outcomes (drawing a king) to the total number of possible outcomes (drawing any card from the deck).
The total number of possible outcomes is 52 because there are 52 cards in the deck.
The favorable outcomes, in this case, are the four kings.
Therefore, the probability of drawing a king is given by:
Probability = (Number of favorable outcomes) / (Number of possible outcomes)
= 4 / 52
= 1 / 13
Thus, the probability of drawing a king from a standard deck of 52 cards is 1/13.
This means that out of every 13 cards drawn, on average, one of them will be a king.
It is important to note that the probability of drawing a king remains the same regardless of any previous cards that have been drawn or any other factors.
Each draw is independent, and the probability of drawing a king is constant.

Fernando loves to make music playlists. He likes to keep the same ratio of country songs to rock songs. On his summer playlist, he has 100 country songs and 24 rock songs. On his road trip playlist, Fernando has 25 country songs.
How many rock songs are on Fernando's road trip playlist?
Answers
Answer:
There are 6 rock songs on Fernando's road trip playlist.
Step-by-step explanation:
Given that he keeps the ratio same
This means that the ratios for both summer playlist and trip playlist will be the same
Let
c1 be the country songs in summer playlist
r1 be the rock songs in trip playlist
Similarly,
c2,r2 will be the country and rock songs in trip playlist
Both will be equal so
\(\frac{c_1}{r_1} = \frac{c_2}{r_2}\)
Putting the values
\(\frac{100}{24} = \frac{25}{r_2}\\100r_2 = 25*24\\100r_2 = 600r_2 = \frac{600}{100}\\r_2 = 6\)
Hence,
There are 6 rock songs on Fernando's road trip playlist.
