The sum given to the kindergarten was reduced by 15%.
How to solve this problemLet's first find out how much money the kindergarten spent in March:
Books: 10% of $2000 = 0.1 x $2000 = $200Food: 70% of $2000 = 0.7 x $2000 = $1400Cleaning services: $2000 - $200 - $1400 = $400So, in April, the kindergarten spent the same amount on books, which was $200. It also reduced its spending on food by $240, which means it spent:
Food: $1400 - $240 = $1160
The remaining 20% of the sum given in April was spent on cleaning services, which means:
Cleaning services: 20% of sum given in April = 0.2 x $x (where x is the sum given in April)
We can set up an equation based on the above information:
$200 + $1160 + 0.2x = x
Simplifying and solving for "x":
$1360 + 0.2x = x
0.8x = $1360
x = $1700
Therefore, the sum given to the kindergarten in April was $1700, which means it was reduced by:
($2000 - $1700) / $2000 x 100% = 15%
So, the sum given to the kindergarten was reduced by 15%.

2/3 of a class are girls. What is the ratio girls to boys in the class? What is the ratio boys to girls in the class?
Answer:
If a class has 2/3 girls.
Lets ask ourselves, what does this mean?
It means that 2/3 of the class are girls and therefore 1/3 of the class are boys. I.e. for every 2 girls in the class there is 1 boy in the class.
Therefore the ratio of girls to boys is

Are the terms 2x and -5x like or unlike terms?
Answer:
The terms 2x and -5x are like terms.
Step-by-step explanation:
Like terms are terms that have the same variable(s) raised to the same power(s). In this case, both 2x and -5x have the same variable "x" raised to the same power "1". The only difference between them is the coefficient, which is 2 for 2x and -5 for -5x. However, the coefficients do not affect whether two terms are like or unlike terms.
So, because 2x and -5x have the same variable raised to the same power, they are like terms.
Kate walks at an average speed of (x + 2) km/h for (x-3) hours and cycles at an average speed of (3x + 5) km/h for x hours. She covers a total of 74 km. Find the time taken for her entire journey
Therefore , the solution of the given problem of equation comes out to be Kate's complete journey took her about 5.22 hours.
What is equation?Variable words are commonly used in complex algorithms to show consistency between two contradictory claims. Academic expressions called equations are used to show the equality of various academic numbers. Instead of another algorithm that can analyze data given by y + 7, split 12 to two parts, and produce y + 7, leveling produces b + 7 in this instance.
Here,
First, let's construct the solution utilizing the distance formula:
Walking distance plus cycling distance equals total distance.
Distance equals speed times time.
=> [(x+2)(x-3)] + [(3x+5)(x)] = 74
Simplifying and finding x's value:
=> x² - 4x - 9 + 3x² + 5x = 74
=> 4x² + x - 83 = 0
Making use of the quadratic formula:
=> x = [-1 + √(1 - 4(4)(-83))] / 8
=> x = [-1 ± √(1337)] / 8
=> x ≈ 4.11 or x ≈ -5.11
We can disregard the bad outcome because time cannot be negative.
Consequently,
=> x = 4.11.
Now that we know how long the full journey took, we can:
=> Time taken = x + (x-3)
=> Time spent = 2x - 3
=> Using x instead of 4.11:
=> Duration: 5.22 hours
As a result, Kate's complete journey took her about 5.22 hours.

Find the sum of the first 19 terms of the arithmetic sequence 2, 3, 4, 5, ...
The sum of the first 19 terms of the arithmetic sequence 2, 3, 4, 5, ... is 209.
To find the sum of the first 19 terms of the arithmetic sequence 2, 3, 4, 5, ..., we need to use the formula for the sum of an arithmetic sequence:
Sₙ = n/2 (a₁ + aₙ)
where Sₙ is the sum of the first n terms of the sequence, a₁ is the first term of the sequence, aₙ is the nth term of the sequence, and n is the number of terms we want to sum.
In this case, a₁ = 2 (the first term of the sequence), aₙ = 2 + (n - 1) = n + 1 (the nth term of the sequence), and n = 19 (we want to sum the first 19 terms of the sequence).
Therefore, we can plug these values into the formula and get:
S₁₉ = 19/2 ˣ (2 + 19 + 1)
= 19/2 ˣ 22
= 209
So the sum of the first 19 terms of the arithmetic sequence 2, 3, 4, 5, ... is 209.

Alan found the distance between point A(-8, -4) and point B(3, -4). His worn is shown below. -8 to the y-axis=8 units. 3 to the y-axis=3 units. |-8| - |3| = 5 units from A to B. What error did Alan make? What is the actual distance from point A to point B?
Answer:
Step-by-step explanation:
Alan made an error in assuming that the distance between -8 and 3 on the x-axis is the same as the distance between -8 and the y-axis, and between 3 and the y-axis. This is not necessarily true, as the distance between two points on a coordinate plane is given by the Pythagorean theorem:
distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)
Using this formula, we can find the actual distance between points A and B:
distance = sqrt((3 - (-8))^2 + (-4 - (-4))^2)
distance = sqrt(11^2 + 0^2)
distance = sqrt(121)
distance = 11
So the actual distance between points A and B is 11 units.
Therefore, Alan's error was assuming that the distance between A and B is simply the difference in the x-coordinates, which is not the case.
A taxi ride costs $1.25 plus 50 cents for each mile, and 30 cents for each minute for waiting time. How much does a 6 mile ride costs if 2.5 minutes are spent eating at stoplights?
Answer: $5.00
Step-by-step explanation:
The cost of a 6-mile ride is made up of three components: a base fare of $1.25, a distance charge of 50 cents per mile, and a waiting charge of 30 cents per minute for the time spent eating at stoplights.
The distance charge for a 6-mile ride is:
6 miles x $0.50/mile = $3.00
The waiting charge for 2.5 minutes at 30 cents per minute is:
2.5 minutes x $0.30/minute = $0.75
So the total cost of the ride is:
$1.25 (base fare) + $3.00 (distance charge) + $0.75 (waiting charge) = $5.00
Therefore, a 6-mile taxi ride with 2.5 minutes of waiting time at stoplights costs $5.00.
There is a 20% chance that a particular volcano will erupt during any given decade. A random number generator generated 10 sets of random numbers from 1 to 5 as shown. The number 1 represents the volcano erupting. Find the experimental probability that the volcano will erupt in 1 or 2 of the next 5 decades
A rough estimate of the actual probability is [tex]0.43[/tex], or [tex]43[/tex]%.
What is the probability synthesis?When compared to a collection of possible occurrences that do not occur, probability may be thought of as a numerical indicator of how likely it is that an event will occur. All potential outcomes must be known as a set.
What makes probability significant?Information about the possibility that a certain thing will happen is provided by probability. For instance, meteorologists utilise weather patterns to forecast the likelihood of rain. Probability theory is utilised in epidemiology to comprehend the connection between exposures as well as the risk of health outcomes.
In three of the seven experiments, the volcano erupted once or twice throughout the course of the next half century (trial 1, 3, and 7).
Trial 1: 1 eruption
Trial 2: 0 eruptions
Trial 3: 1 eruption
Trial 4: 0 eruptions
Trial 5: 0 eruptions
Trial 6: 0 eruptions
Trial 7: 2 eruptions
Therefore, the experimental probability that the volcano will erupt in [tex]1[/tex] or [tex]2[/tex] of the next [tex]5[/tex] decades is:
experimental probability [tex]=[/tex] number of successful trials / total number of trials
experimental probability [tex]= 3 / 7[/tex]

In other words, it is the surface area of the object's lateral or side faces. The lateral surface area is typically used to describe the surface area of certain geometric solids such as cylinders, cones, and prisms. In the case of a cylinder, for example, the lateral surface area is the area of the curved side of the cylinder, excluding the top and bottom circular faces. For a cone, the lateral surface area is the area of the curved side of the cone, excluding the circular base.

As It takes Sara 1/2 day to make a birdhouse, the number of birdhouse which will be built after 2/5 day is 4/5 of a birdhouse.
How many birdhouse will be built after 2/5 day?Since it takes Sara 1/2 day to make a birdhouse, we can say that she can make 2 birdhouses in one day.
So, after 1/2 day, Sara will complete 1 birdhouse.
Now, let's see how much of the birdhouse Sara can build after 2/5 day:
2/5 day is equivalent to (2/5) x (1/2) = 1/5 day.
Since Sara can build 1 birdhouse in 1/2 day, she can build 1/2 of a birdhouse in 1/4 day (half of 1/2 day).
Therefore, in 1/5 day, she can build:
= (1/5) / (1/4)
= (1/5) x (4/1)
= 4/5 of a birdhouse.

The casino manager anticipates that, during the next week, 25000 bets of the same type ($1 bet on red color) will be placed at all the (American) roulette tables. Assume independence for the corresponding roulette spins, and that the Central Limit Theorem provides an accurate approximation to the distribution of the casino’s total profit from the 25000 bets. What is the probability that the casino’s total profit will exceed $1000?
The probability that the casino's total profit will exceed $1000 is very close to zero.
What is the probability that the casino’s total profit will exceed $1000?The probability of winning a bet on red in American roulette is 18/38, and the probability of losing is 20/38.
Therefore, the expected profit for the casino on each bet is:
E(profit per bet) = (18/38) x ($1) + (20/38) x (-$1) = -$0.0526
The variance of the profit per bet can be calculated as follows:
Var(profit per bet) = (18/38) x ($1 - (-$0.0526))^2 + (20/38) x (-$1 - (-$0.0526))^2 = $0.921
The standard deviation of the profit per bet is the square root of the variance, which is approximately $0.960.
The expected profit for the casino from 25000 bets is:
E(total profit) = 25000 x (-$0.0526) = -$1315
The standard deviation of the total profit is the square root of the variance multiplied by the number of bets, which is approximately $305.46.
To find the probability that the casino's total profit will exceed $1000, we can standardize the distribution of the total profit as follows:
z = (1000 - (-$1315)) / $305.46 = 9.48
Using a standard normal table or calculator, we can find that the probability of a standard normal variable exceeding 9.48 is essentially zero.

Suppose we want to choose 6 objects without replacement from 14 distinct objects
If we want to choose 6 objects out of 14 objects and the order does not matter, then the number of ways we can do this is 3003.
How to calculate the number of ways the objects can be selected?The number of ways you can select or organize objects is defined by formulas of permutation and combination. Choosing one or the other depends on whether the order matters (permutation) or not (combination). In this case, as the order does not matter, the general formula is:
C = n! / r! (n-r)!
In this formula, n is the total of items and r is the total I need to select. Let's then solve it:
C= 14! / 6! (14! - 6!)
C = 14! / 6! 8!
C= 14 x 13 x 12 x 11 x 10 x 9 / 6 x 5 x 4 x 3 x 2
C= 7 x 13 x 11 x 3
