Step-by-step explanation:

a) The probability that the test comes back negative for all six people is  95.8%,

b)  The probability that the test comes back positive for at least one of the six people is 4.2%.

(a) To find the probability that the test comes back negative for all six people, we can use the fact that the test is 99.3% effective in accurately detecting the absence of the antibody.

Since the test is 99.3% effective, the probability of it coming back negative for each individual who does not have the antibody is 0.993. Therefore, the probability that the test comes back negative for all six people is calculated as follows:

P(negative for all 6) = (0.993)^6 ≈ 0.958

Therefore, the probability that the test comes back negative for all six people is approximately 0.958, or 95.8%.

(b) To find the probability that the test comes back positive for at least one of the six people, we need to consider the probability of a false positive.

The probability of a false positive, which is the probability of the test coming back positive when the antibody is not present, is given as 0.007. Therefore, the probability of the test correctly identifying the absence of the antibody is 1 - 0.007 = 0.993.

The probability that the test comes back positive for at least one person is the complement of the probability that the test comes back negative for all six people. So we can calculate it as follows:

P(positive for at least one person) = 1 - P(negative for all 6) ≈ 1 - 0.958 = 0.042

Therefore, the probability that the test comes back positive for at least one of the six people is approximately 0.042, or 4.2%.

In summary, the probability that the test comes back negative for all six people is approximately 95.8%, while the probability that the test comes back positive for at least one of the six people is approximately 4.2%.

The simplified expression is \(-4x^2 + 3x + 1\), which is a quadratic polynomial. Option D.

To simplify the expression \((8x^2 + 3x) - (12x^2 - 1)\), we can distribute the negative sign to each term within the parentheses:

\(8x^2 + 3x - 12x^2 + 1\)

Next, we can combine like terms by adding or subtracting coefficients of similar powers of x:

\((8x^2 - 12x^2) + 3x + 1\)

Simplifying further, we have:

\(-4x^2 + 3x + 1\)

The resulting polynomial \(-4x^2 + 3x + 1\) is a quadratic polynomial since it has a highest power of x^2 (the exponent of x is 2), which is\(-4x^2.\)Quadratic polynomials are polynomials of degree 2 and can be represented by a parabola when graphed.

In summary, the simplified expression \((8x^2 + 3x) - (12x^2 - 1)\) simplifies to \(-4x^2 + 3x + 1\) , which is a quadratic polynomial. So Option D is correct

Note the complete question is

The probability the letter Julianna draws is NOT the letter A is 0.75

Julianna wrote each of the 8 letters in her name on same-sized pieces of paper, so there are 8 possible outcomes when she randomly draws one paper from the bag.

Out of the 8 letters, two letter is A.

So, the probability of drawing the letter A is 2/8 = 1/4

The probability of not drawing the letter A is the complement of this probability, which is:

1 - 1/4 = 3/4

This gives

1 - 1/4 = 0.75

Therefore, the probability, in decimal form, that the letter on the paper Julianna draws is not the letter A is 0.75

We have,

In a box-and-whisker plot, the box represents the interquartile range (IQR), which includes the middle 50% of the data.

The line within the box represents the median.

The "whiskers" extend to the minimum and maximum values, excluding any outliers.

Given the information provided:

Median = 41

Q1 = 37

Q3 = 49

Largest = 55

Smallest = 35

Since Q3 represents the upper quartile and corresponds to the boundary for the upper 25% of the data, we can conclude that 25% of the employees took a break longer than 49 minutes.

Now,

The number of employees who took a break longer than 49 minutes can be estimated by calculating 25% of the total number of employees:

25% of 27 employees

= (25/100) x 27

= 6.75

Since we cannot have a fractional number of employees, we round up to the nearest whole number.

Therefore,

Approximately 7 employees took a break longer than 49 minutes.

Answer:

m<1 = 50°

m<2 = 130°

m<3 = 50°

m<4 = 130°

m<5 = 50°

m<6 = 130°

m<7 = 50°

m<8 = 130°

Step-by-step explanation:

Angle 4 & Angle 2 are congruent angles because they are diagonal from each other, this lets us set m<4 = m<2.

Then solve for x.

2x-10 = x+60

x-10 = 60

x = 70

Use x to find m<4 or m<2 (doesn't matter which b/c they are equal).

m<2 = (70)+60

m<2 = 130°

Angles 2, 4, 6 & 8 are congruent, so they will all have be 130°.

Angles 1 & 2 create a straight line (180°).

Find m<1 by subtracting 130° from 180°.

180-130 = 50

Angles 1, 3, 5 & 7 are also congruent, so they will all have be 50°.

The correct answer is $1530 as determined by logical reasoning.

What is logical reasoning ?

The 3 types of logical logic-

A proper or reasonable way of allowing about commodity.

DIRECTV:

($30)(6) + ($75)(18) = $1530

Current:

($50)(24) + $1200

Do not switch providers.

You shouldn't switch providers because, in the long run, you'll be paying lower plutocrat with your current provider than with DIRECTV. Emotionally, you may want to buy DIRECTV's contract because of the delineation; still, there's a low probability that you would actually be chosen, so it isn't worth the increase in payments.

From given sample space, No. of toothpicks each student will get is 51.

What exactly is a sample space?

In mathematics, a sample space is the set of all possible outcomes of an experiment or a random phenomenon. It is denoted by the symbol "S" and is a fundamental concept used in calculating probabilities. For example, when flipping a coin, the sample space is {heads, tails}. When rolling a fair six-sided die, the sample space is {1, 2, 3, 4, 5, 6}. The sample space for a more complex event may involve multiple variables and outcomes.

Now,

Total Toothpicks = 918

Total students = 18

then

Toothpicks per student = 918/18=51

Hence,

           No. of toothpicks each student will get is 51.

98,329.16 is the Growing Ordinary Annuity's Future Value (FV). Given a predetermined rate of return or discount rate, the present value of an annuity is the entire cash worth of all of your future annuity payments.

A sequence of equal-spaced payments constitutes an annuity. There are a lot of real-world examples of financial transactions involving annuities, including. • an automobile loan with a set repayment schedule of equal monthly payments.

Calculating the present value of an annuity is done by multiplying the dollar amount of each payment by the following formula:\(P = PMT \times [1- [ (1 / 1+r)^n] / r]\)  where P is the present value of your annuity stream. PMT is short for payment method type.

A set of periodic payments that will be received in the future at the start of each period or at its conclusion is referred to as a "annuity." The formula used to determine annuity payments and annuities due is based on the PV of annuities due, the effective interest rate, and the number of periods.

Answer:

Step-by-step explanation:

You can observe a representation of this problem in the image attached.

Notice that the grass seed is gonna be put only in the green zone, out of the pond. So, we need to find each area and subtract them.

\(A_{garden}= 14 \times 9 =126 \ m^{2} \\A_{pond}=2.4 \times 3.8 = 9.12 \ m^{2}\)

The difference is

\(A_{seed}=126 - 9.12 = 116.88 \ m^{2}\)

Now, according to the problem, one box of grass seed covers 15 meters of the garden, let's divide this number with the seed area.

\(n=\frac{116.88}{15} \approx 7.792\)

Therefore, Kayla needs 8 boxes of grass seed to cover the whole garden without including the pond.

-5/2 = A

√4 = 2 = E

1/3 = D

-√2 = B

Explanation:

We need to determine the position of the numbers given:

-√(1/4) = -(√1)/(√4) = -(1/2) = - 0.5

-5/2 = - 2.5

√4 = 2

1/3 = 0.33

-√2 = -1.4

We check the number line for alphabets that represent these numbers.

-0.5 is between 0 and -1

-√(1/4)= -0.5 = C

-2.5 is between -2 and -3

-5/2 = -2.5 = A

Alphabeth E is on 2

√4 = 2 = E

0.3 is between 0 and 1. it's closer to 0

1/3 = D

-1.4 is between -1 and -2. It is closer to -1
