Answer:

355 ounces

Step-by-step explanation:

Okay! We're going to have to use some conversion factors for this problem, since we're working with two different units (pounds and ounces). We know that there are 16 ounces in a pound - that's our first conversion factor. We can use it to write up a little equation to help us:

\(\frac{22lbs}{1} *\frac{16oz}{1lb} + 3 = x\)

"x" is the total amount of ounces. Does everything in that equation make sense? The first multiplication part tells us how many ounces are in 22 pounds, and the second part (+ 3) adds the 3 ounces that were there from the beginning. Now, it's time to calculate.

\(\frac{22bs}{1} *\frac{16oz}{1lb} + 3 = x\\\)

\(\frac{352oz}{1} + 3 = x\)

\(352+3 = x\)

\(x=355\)

So, there are 355 ounces in a bike that weighs 22 pounds and 3 ounces. Hopefully that's helpful! :)

Answer:

A quadratic inequality is an equation of second degree that uses an inequality sign instead of an equal sign. The solutions to quadratic inequality always give the two roots. The nature of the roots may differ and can be determined by discriminant (b2 – 4ac).

The mean IQ score in the population is approximately 98, and the standard deviation is approximately 16.

Let μ = mean and σ = standard deviation of IQ scores in population.

Then we can write the two equations as :

⇒ P(X ≤ 80) = 0.13    ...equation(1)

⇒ P(X ≥ 128) = 0.03   ...equation(2)

we standardize the data by using the formula:

⇒ Z = (X - μ)/σ,

Where Z = standard normal variable.

Using the standard normal distribution, we know that P(Z ≤ -1.126) = 0.13,

So, -1.126 = (80 - μ)/σ   .....equation(3),

and we know that P(Z ≥ 1.881) = 0.03.

So, 1.88 = (128 - μ)/σ     ...equation(4),

⇒ μ = 128 - 1.881σ,

Solving equation(3) and equation(4),

We get,

⇒ σ ≈ 16.

Substituting σ = 16 into the equation(4),

We get,

⇒ μ = 128 - 1.881×16,

⇒ μ = 98.

Therefore, the mean IQ score = 98, and standard deviation is = 16.

2.2.1: The value of the expression 3sin(8-1)-2 is approximately -0.032.

2.2.2: The approximate value of √2 is approximately 1.0152 when cos(0 + 10°) = 1.

To clarify, it seems that you have two separate expressions that you would like assistance with:

3sin(8-1)-2

√2cos(0 + 10°) = 1

Let's solve each of them step by step:

3sin(8-1)-2:

First, simplify the expression inside the sine function:

8-1 = 7.

Now we have:

3sin(7)-2.

Evaluating the sine of 7 (in radians), we get:

sin(7) ≈ 0.656.

Substituting this value back into the expression, we have:

3 × 0.656 - 2.

Calculating the result, we get:

1.968 - 2 = -0.032.

The value of the expression 3sin(8-1)-2 is approximately -0.032.

√2cos(0 + 10°) = 1:

First, evaluate the expression inside the cosine function:

0 + 10° = 10°.

Next, convert 10° to radians:

10° × (π/180) ≈ 0.1745 radians.

Now we have:

√2cos(0.1745) = 1.

Evaluating the cosine of 0.1745, we get:

cos(0.1745) ≈ 0.9848.

Substituting this value back into the expression, we have: √2 × 0.9848 = 1.

To solve for √2, divide both sides of the equation by 0.9848:

√2 ≈ 1 / 0.9848

≈ 1.0152.

The given series ∑k=2[infinity]1k−1 converges. Since the series ∑k=1[infinity]1/k diverges, the series ∑k=2[infinity]1/(k-1) also diverges by the Comparison Test.

To prove this using the Comparison Test, we compare it to the series ∑k=1[infinity]1k, which is a harmonic series.

For k > 2, we have 1k−1 ≥ 1k since the exponent on the denominator decreases by 1.

The series ∑k=1[infinity]1k is a harmonic series, and it is known to diverge.

Since 1k−1 ≥ 1k for k > 2 and the series ∑k=1[infinity]1k diverges, we can conclude that the series ∑k=2[infinity]1k−1 also diverges.

Therefore, the given series ∑k=2[infinity]1k−1 diverges by the Comparison Test.

Let X be a random variable, and K be a random variable which takes values in non-negative integers. It is given that K has density function G(k) such that G(0) = 0 and G(k-1) = g(k). Let z(k) be a non-negative, monotonic function such that E[x(K)] exists.

The expected value of the random variable X can be written as follows:$$E[X] = \sum_{k=0}^{\infty} x(k) G(k)$$Similarly, the expected value of the function z(K) can be written as follows:$$E[z(K)] = \sum_{k=0}^{\infty} z(k) G(k)$$By the definition of expectation, we can write the above as follows:

$$\int u dv = uv - \int v du$$$$\Rightarrow \int z(k-1) G(k-1) dk = z(k-1) G(k) - \int G(k) z'(k-1) dk$$Now we can write the above equation in summation notation and rearrange the terms as follows:$$\sum_{k=1}^{\infty} z(k-1) G(k-1) = \sum_{k=1}^{\infty} [z(k-1) - z(k)] G(k) + z(0) G(0)$$Substituting this in the expression for E[z(K)], we get:

$$E[z(K)] = \sum_{k=1}^{\infty} [z(k-1) - z(k)] G(k) + z(0) G(0)$$$$\Rightarrow E[z(K)] = z(0) G(0) + \sum_{k=1}^{\infty} [z(k-1) - z(k)] G(k)$$
