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.

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

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.

Answer:

h = 6

Step-by-step explanation:

h is the short leg for AD in ΔADC: AD = 12

h is the long leg for DB in ΔCDB: DB = 3

Hence:

12/h = h/3

3 * 12/h = 3 * h/3  ==> isolate h by multiplying 3 on both sides

36/h = h

h * 36/h = h*h  ==> multiply by h on both sides to remove fractions

36 = h^2

h = [tex]\sqrt{36}[/tex]

h = 6

The answer is option 3: approval ratings tended to fall as stock prices rose.

This means that when stock prices rose, the approval ratings of George Bush's presidency decreased. This can be interpreted as an indication that people were not satisfied with the performance of the stock market during the Bush presidency. This could be because the stock market was not performing as well as expected or because the people were not satisfied with the decisions made by the Bush presidency that impacted the stock market.

Whatever the reason, the negative correlation between the stock market performance and Bush's approval ratings shows that when stock prices rose, approval ratings tended to fall.

80% is her free throw shooting percentage.

Fractions are used to represent smaller pieces (or parts) of a whole. The parts might make up one thing, or more than one thing. Either way, altogether, they make up what's called a whole.

Given that, Jeremiah makes 4/5 of the free throw shots he attempts in basketball. Jeremiah likes to shoot free throws until he misses one. Let F be the number of shots it takes Jeremiah to miss his first free throw.

We can construct a fraction in which the numerator is how many shots she makes, and the denominator is how many shots she took overall.

We now have the following fraction:4/5

To convert this to a percentage, we want the denominator to be 20/20

= 4/5×20/20

= 80/100

= 0.8

Now multiply 0.8 with 100

= 0.8×100=80

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.

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

That means, if Jim visits 5 times, the gym, then he would have the similar cost for both of the plans.

She expects to have $2710591.78 when she retires at age 65 with the principal amount is 398100, the interest rate is 8%, time period is 24 and number of times interest applied is 3 by the concept of compound interest.

Interest that is paid on the principal and interest at regular periods is known as compound interest. The interest is calculated for the new principal at regular intervals after the interest that has already accumulated has been combined with the existing principal amount. The initial principal plus the interest that has accrued thus far are added together to form the new principal.

Interest on the principal + periodic compound = compound interest.

According to the question the principal amount is 398100, the interest rate is 8%, time period is 24 and number of times interest applied is 3.

Here the interest is compounded every 4 months

So, the formula of compound interest is as follows:

A=p (1+ [tex]\frac{r}{n}[/tex]) ∧ (n× t)

Where P is the principal balance, r is the interest rate, n is the number of times interest is compounded per year and t is the number of years.

Here the interest is compounded every 4 months hence the value of n is 12/4 which is equal too 3.

Insert the values of p, n, t, r in above equation,

A=398100(1+[tex]\frac{8}{300}[/tex]) ∧ (3×24)

A=398100× (1.027) ∧ (72)

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
