Answer:

To round a number to the nearest thousand, we first need to identify the thousands digit in the number. In this case, the thousands digit is 8, because 87388 is between 80000 and 90000.

To determine whether to round up or down, we need to look at the hundreds digit, which is 7 in this case. If the hundreds digit is 5 or greater, we round up. If the hundreds digit is less than 5, we round down. In this case, the hundreds digit is 7, which is greater than or equal to 5, so we need to round up.

To round up, we add 1000 to 87388, which gives us 88388. So, 87388 rounded to the nearest thousand is 88000.

To find the minimum number of daisies and lilies that Manuel must have watered, we need to find the least common multiple (LCM) of 11 and 12. The LCM of two numbers is the smallest positive integer that is a multiple of both numbers.

To find the LCM of 11 and 12, we can list the multiples of each number and find the smallest number that appears in both lists. The multiples of 11 are 11, 22, 33, 44, 55, 66, 77, 88, 99, 110, 121, etc. The multiples of 12 are 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, etc.

We can see that the smallest number that appears in both lists is 11, which is the LCM of 11 and 12. Therefore, the minimum number of daisies and lilies that Manuel must have watered is 11. If he watered the same number of each flower, he must have watered at least 11 daisies and 11 lilies.

LCL would be 4 minutes and UCL would be 6 minutes if the company uses 2-sigma control limits instead.

The average of a group of variables is referred to as the mean in mathematics and statistics. There are several methods for calculating the mean, including simple arithmetic means (adding the numbers together and dividing the result by the number of observations), geometric means, and harmonic means. The arithmetic mean, also known as the arithmetic average or simply the mean or average, is the sum of a set of numbers divided by the total number of numbers in the set. The collection frequently consists of a series of findings from a survey, experiment, or observational study.

Given

LCL = 3.5 minutes

UCL = 6.5 minutes

Mean = LCL + UCL/2

Mean = 3.5 + 6.5/2

Mean = 5

Standard deviation = UCL - LCL/6

Standard deviation = 6.5 - 3.5/6

Standard deviation = 0.5

LCL = 5 - 2(0.5)

LCL = 4

UCL = 5 + 2(0.5)

UCL = 6

The equation that can be used to find b, when E and n are known is: b = (E - 12n) / 8.

This equation can be derived from the original equation of E=8b+12n. To solve for b, we can start by subtracting 12n from both sides of the equation to isolate b. We then divide both sides of the equation by 8 in order to solve for b.

The result is b = (E - 12n) / 8. This equation can be used to find the number of bracelets (b) when the total earnings (E) and the number of necklaces (n) are known.

We can rearrange the equation to solve for b.

E = 8b + 12n

Subtract 12n from both sides:

E - 12n = 8b

Divide both sides by 8:

(E - 12n)/8 = b

Therefore, the equation to find b, when E and n are known, is:

b = (E - 12n)/8

Step-by-step explanation:

To determine whether the college graduate will have $200,000 saved in their retirement account after 25 years, we can use the formula for compound interest:

A = P * (1 + r/n)^(nt)

where A is the total amount of money in the account after the specified time, P is the initial amount of money deposited in the account, r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the number of years the money is invested.

In this case, the initial amount deposited each month is $150, the annual interest rate is 10%, the number of times the interest is compounded per year is 12 (once per month), and the number of years the money is invested is 25. Plugging these values into the formula above gives us:

A = $150 * (1 + 10%/12)^(12*25) = $150 * (1.0083)^300 = $150 * 3.4955 = $524.33

Since the goal is to have $200,000 saved in the account after 25 years, the college graduate will not have enough money in their account if they contribute $150 per month at 10% interest. In order to reach their goal, they would need to save more money each month or earn a higher interest rate on their contributions.

The list of pairs of triangles are ∠A≅∠N, ∠B≅∠O, ∠C≅∠P for the given similar triangles.

Triangles are polygons because they have three vertices and three edges. This is one of the basic shapes in geometry.

In Euclidean geometry, any three non-collinear points determine a distinct triangle and a distinct plane (i.e. a two-dimensional Euclidean space). To put it another way, every triangle has a plane that it is contained in, and there is only one plane that contains every triangle. If and only if all geometry is the Euclidean plane, all triangles are contained in a single plane; however, this is no longer true in higher-dimensional Euclidean spaces.

Given triangles are,

The same cost of both of the plan of the gym will be in 5 visits. And plan B is better than Plan A as B is cheaper than A.

In mathematics, expression is the combining of variables with the application of operations and prescribed rules. It could take the shape of an equation, some numbers, etc.

We have,

plan A consists of :

Amount for monthly membership fee = $50

Cost per visit = $10

The expression of total fees would be:

50+10x,

where x is the number of times Jim visits the gym.

Plan B consists of :

Amount for monthly one time membership fee = $25

Cost per visit = 15

The expression of total fees would be:

25 + 15x,

where x is the number of times Jim visits the gym.

Here, x denotes the number of visits.

Let us suppose x = 1

Then, fees for plan A would be:

50 + 10 x1 = $60

Fees for plan B would be:

25 + 15 x1 = $40

To find the same cost in x number of visits:

We equate both the expressions.

50+10x = 25 + 15x

15x - 10x = 50 - 25

5x = 25

x = 5

An inequality that can represent the sum of a number and 11.5 is more than −4.5 is  b + 11.5 > −4.5 .

What is inequality?

In mathematics, a relationship between two expressions or values that are not equal to each other is called ‘inequality.’ So, a lack of balance results in inequality. For example, if you want to buy a new bicycle that costs 250 but you have 225. It is also an inequality as you are comparing two numbers that aren’t equal.

We use ‘=’ when two quantities are equal and when they are not equal we use the symbol ≠ to denote not equal. If two things are not equal, the first value can be either greater than (>) or lesser than (<) or greater than equal to (≥) or less than equal to (≤) the second value. So, as per the above example, 250 > 225.

Given :  the sum of a number and 11.5 is more than −4.5

Let us assume the number be "b"

according to question,

b + 11.5  is more than −4.

So the expected value of the remainder when M is divided by 64 is approximately 0.2080.

To find the expected value of the remainder when M is divided by 64, we can find the probability that M is congruent to each possible remainder modulo 64 and then sum these probabilities multiplied by the corresponding remainders.

For a positive integer n, let P(n) denote the probability that a positive integer chosen from the set {1, 2, . . . , 100} is congruent to n modulo 64. Then

P(0) = P(64) = P(128) = ... = 1/100

P(1) = P(65) = P(129) = ... = 1/100

P(63) = P(127) = P(191) = ... = 1/100

Since the integers a, b, c, d, e, and f are chosen independently and uniformly at random from the set {1, 2, . . . , 100}, the probability that M is congruent to n modulo 64 is P(n)^6.

Therefore, the expected value of the remainder when M is divided by 64 is

E = 0 * P(0)^6 + 1 * P(1)^6 + 2 * P(2)^6 + ... + 63 * P(63)^6

= (0^6 + 1^6 + 2^6 + ... + 63^6) * P(0)^6

= (0 + 1 + 2 + ... + 63) * P(0)^6

= 2080 * (1/100)^6

= 0.2080

So the expected value of the remainder when M is divided by 64 is approximately 0.2080.
