To find the probability of obtaining a value greater than or equal to 80 but less than or equal to 115 for a normal distribution with a mean of 100 and standard deviation of 10 using Excel, you can use the NORM.DIST function.

Here's how you can do it step-by-step:

1. Open Excel and enter the following formula in a cell: =NORM.DIST(115,100,10,TRUE) - NORM.DIST(80,100,10,TRUE)
  - The first argument (115) is the upper bound of the range (inclusive).
  - The second argument (100) is the mean.
  - The third argument (10) is the standard deviation.
  - The fourth argument (TRUE) specifies that you want the cumulative distribution.
  - Similarly, for the second part of the formula, use the lower bound (80).

2. Press Enter to calculate the formula. The result will be the probability of obtaining a value within the specified range.

The NORM.DIST function calculates the probability of a value occurring in a normal distribution. By subtracting the probability of the lower bound from the probability of the upper bound, you get the probability of obtaining a value within the desired range.

To find the probability using Excel, you can use the NORM.DIST function. By subtracting the cumulative distribution function (NORM.DIST) of the lower bound (80) from the cumulative distribution function of the upper bound (115), you can calculate the probability of obtaining a value within the specified range. The NORM.DIST function requires four arguments: the value you want to calculate the probability for, the mean, the standard deviation, and whether you want the cumulative distribution. In this case, the mean is 100 and the standard deviation is 10. By entering the formula in Excel, you can calculate the probability of obtaining a value between 80 and 115 for this normal distribution.

C. (∃x)(A(x) ∧ B(x)) ⇔ (∃x)A(x) → (∀y)B(y)

This statement is incorrect. The left-hand side states that there exists an x such that both A(x) and B(x) are true.

Therefore, the incorrect statement is option C.

A = {{1, 2, 3}, {4, 5}, {6, 7, 8}}

Hence. Option D is wrong.

In set theory, a subset relation is denoted by ⊆, and a proper subset relation is denoted by ⊂. A subset relation indicates that all elements of one set are also elements of another set.

In this case, let's evaluate the options:

A. ∅ ⊆ A: This option is correct. The empty set (∅) is a subset of every set, including A.

B. {6, 7, 8} ⊂ A: This option is correct. The set {6, 7, 8} is a proper subset of A because it is a subset of A and not equal to A.

C. {{4, 5}} ⊂ A: This option is correct. The set {{4, 5}} is a proper subset of A because it is a subset of A and not equal to A.

D. {1, 2, 3} ⊂ A: This option is incorrect. The set {1, 2, 3} is not a subset of A because it is not included as a whole within A. The element {1, 2, 3} is present in A but is not a subset.

In conclusion, the incorrect option is D, {1, 2, 3} ⊂ A.

The solution to the inequation -5-11x < -7x + 7 is x > 1. It represents all values of x greater than 1 on the number line.

To solve the inequation -5-11x < -7x + 7, we need to isolate x on one side of the inequality symbol. Let's go through the steps:

-5-11x < -7x + 7

First, let's simplify both sides of the inequality:

-11x + 7x < 7 + 5

-4x < 12

Next, we divide both sides by -4, remembering to reverse the inequality when dividing by a negative number:

x > -3

Therefore, the solution to the inequation is x > -3. This means that any value of x greater than -3 will satisfy the original inequality.

To represent this solution on a number line, we mark a point at -3 and shade the region to the right of it. Since x is greater than -3, the solution includes all values to the right of -3, which is represented by an open circle at -3 and shading to the right.

In summary, the solution to the inequation -5-11x < -7x + 7 is x > -3, and it is represented on the number line by an open circle at -3 and shading to the right.

The system of equations that could be used to determine the number of gift wraps and the gift packs is x + y = 21 and 4.5x + 2y = 79.5

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

A system of linear equations is a collection of at least two linear equations.

In this case, the variables of the system of equations are:

From the question, we have:

Total gift = 21

Total minute = 79.5 minutes

Time spent on single wrap =  4.5 minutes

Time spent on gift pack =  2 minutes

So, we have the following system of equations:

x + y = 21

4.5x + 2y = 79.5

Hence, the system of equations that could be used to determine the number of gift wraps and the gift packs is x + y = 21 and 4.5x + 2y = 79.5

which is an iterative method that can find roots of a polynomial equation given an initial approximation.

According to the fundamental theorem of algebra, how many zeros does the function f(x) = 17x^15 + 41x^12 + 13x^3 − 10 have?The fundamental theorem of algebra states that every polynomial function has at least one zero or root. A polynomial function of degree n can have at most n roots or zeros, so the answer to this question will be less than or equal to the degree of the polynomial. Here, f(x) is a polynomial of degree 15. Therefore, f(x) can have at most 15 zeros or roots.We cannot use the Rational Zeroes Theorem, because the coefficients of f(x) are not integers. However, we can use technology (like a graphing calculator) or numerical methods to approximate the roots.

The number of zeros the function has, however, cannot be determined without approximation.The correct answer is:long answer:According to the fundamental theorem of algebra, every polynomial equation of degree n (where n is a non-negative integer) has exactly n roots. In other words, the polynomial equation f(x) = 17x^15 + 41x^12 + 13x^3 − 10 has exactly 15 roots, counting multiplicity.Since the polynomial f(x) has no rational roots (i.e., roots that can be expressed as a fraction of integers), it cannot be factored using integer coefficients. This makes it difficult to determine the roots of the polynomial analytically.

However, we can use numerical methods or technology to approximate the roots of the polynomial. One such method is to use the Newton-Raphson method, which is an iterative method that can find roots of a polynomial equation given an initial approximation.

Step-by-step explanation:

Susie should report $0 gross income on her tax return.

The true statement is (c) In 2021, the deduction for medical expenses cannot exceed a ceiling calculated as 10% of AGI for a taxpayer age 65 years or older.

For the first question about Susie's gross income, the discount she received on the landscaping services does not count as gross income.

The correct answer is (a) $0.

For the second question, to calculate the modified adjusted gross income (MAGI) of $37,600, we need more information about the taxpayer's specific deductions, exemptions, and adjustments.

Without that information, it is not possible to determine the exact amount of gross income.

Therefore, the answer cannot be determined from the given information.

Moving to the next question, the correct statement is (c) In 2021, the deduction for medical expenses cannot exceed a ceiling calculated as 10% of AGI for a taxpayer age 65 years or older.

This means that medical expenses for taxpayers under the age of 65 cannot exceed 7.5% of their AGI for 2021.

Answer:

$20 - (14/100 * $20) = $17.20

Step-by-step explanation:

The sale price can be calculated by multiplying the original price by the discount percentage (which is 14/100 since the price is discounted by 14 out of 100):

Sale price = Original price - Discount amount

= Original price - (Discount percentage * Original price)

= $20 - (14/100 * $20)

= $20 - $2.80

= $17.20

So, the expression that gives the sale price is:

$20 - (14/100 * $20) = $17.20

The proportion of variation in head circumference that can be explained by the variation in height was calculated to be approximately 49.8%.

If the cost for 10 ounce of organic blueberry is $2. 70, the cost of 30 ounce of organic blueberry is represented by the equation x = 20y + 2.70 where y is the cost in dollars for one ounce of organic blueberry.

As x is the cost in dollar for 30 ounce of organic blueberry. For y is the cost in dollars for one ounce of organic blueberry, then

x = 30y + c

where c is the fixed cost

We know for 10 ounce of organic blueberry it costs $2.70. That is

2.70 = 10y + c

c = 2.70 - 10y

So x = 30y + 2.70 - 10y
