If a household on malias block is selected at random and does subscribe to cable television, what is the probability the members of the household also subscribe to home phone service?

Answer:

7 years

Step-by-step explanation:

The required, simplified expression is 2x - 6y(2a - x) + 6y.

To simplify the expression (2x+6yx)-(12ay+-6y), we need to distribute the negative sign to the second term.

2x - 6y(2a - x) + 6y.

Now we can combine like terms, which means adding up any terms that have the same variables raised to the same powers. In this case, we have two terms with "x" and two terms with "y". Combining them, we get:

2x+6yx-12ay+6y = 2x - 12ay + 6yx + 6y
                           = 2x - 6y(2a - x) + 6y

Answer:

Pregnant women have the option of being scanned for Cystic Fibrosis risks in their unborn babies. If a mother or a father have a certain recessive gene, the baby is at risk for Cystic Fibrosis.

Given the three events, which of the following statements is true?  

Select all that apply.

Event A: The mother or father carries the recessive gene.

Event B: The father carries the recessive gene.

Event C: The baby is at risk for Cystic Fibrosis.

Select all that apply:

Event A and Event B are mutually exclusive.

Event B and Event C are mutually exclusive.

Event A and Event C are not mutually exclusive.

Event A and Event C are mutually exclusive.

Event A and Event C are not mutually exclusive.

Remember that in general, A and B are mutually exclusive events if they cannot occur at the same time. This means that A and B do not share any outcomes and P(A AND B)=0.

In this question, note that if the mother or father carries the recessive gene for cystic fibrosis, the baby is at risk. So here, A and C are not mutually exclusive, and B and C are not mutually exclusive.

A and B are not mutually exclusive because they share an outcome: the father carrying the recessive gene.

            Have a nice day hon.

The possible dimension of the canvas she could use for her paintings is 71.25 cm × 45 cm

The given dimensions of the mountain scenery in the calendar are 28.5 cm × 18 cm.

To make a painting similar to this scenery, Christina needs to use a canvas with the same aspect ratio as the mountain scenery in the calendar. Aspect ratio is the proportional relationship between the width and height of an image or object.

To find the aspect ratio of the mountain scenery in the calendar, we divide the width by the height:

aspect ratio = width / height = 28.5 cm / 18 cm = 1.5833

Now we can calculate the aspect ratio for each of the given canvas options by dividing the width by the height:

42.75 cm × 51 cm has an aspect ratio of 42.75 cm / 51 cm = 0.8382

14.25 cm × 36 cm has an aspect ratio of 14.25 cm / 36 cm = 0.3958

57 cm × 27 cm has an aspect ratio of 57 cm / 27 cm = 2.1111

71.25 cm × 45 cm has an aspect ratio of 71.25 cm / 45 cm = 1.5833

46 cm × 68 cm has an aspect ratio of 46 cm / 68 cm = 0.6765

Only the option 71.25 cm × 45 cm has the same aspect ratio (1.5833) as the mountain scenery in the calendar, so this is the correct answer.

B) 20%

Step-by-step explanation:

Exponential equation:

An exponential equation is given by:

\(A(t) = A(0)(1+r)^t\)

In which A(0) is the initial amount and r is the growth rate, as a decimal.

In this question:

\(P(t) = 85(1.2)^t\)

Growth rate:

We want to find r, so:

\(1 + r = 1.2\)

\(r = 1.2 - 1 = 0.2\)

The growth rate is of 0.2 = 2%, and the correct answer is given by option B.

Answer:

∠ BDC = 29°

Step-by-step explanation:

the sides of a rhombus are congruent, so CD = ED and Δ EDC is therefore isosceles with base angles congruent , then

∠ BCD = ∠ BED = 61°

• the diagonals are perpendicular bisectors of each other , then

∠ CBD = 90°

the sum of the 3 angles in Δ BCD = 180°

∠ BDC + ∠ CBD + ∠ BCD = 180°

∠ BDC + 90° + 61° = 180°

∠ BDC + 151° = 180° ( subtract 151° from both sides )

∠ BDC = 29°

A sample size of at least 44 is required to estimate the population mean with 90% confidence and a margin of error of 5, assuming the population standard deviation is approximately .

To find the sample size required to estimate a population mean with a certain level of confidence and margin of error, we can use the formula:

n = (z * σ / E)^2

where:

n = sample size

z = z-score corresponding to the desired level of confidence (in this case, 90% confidence corresponds to a z-score of 1.645)

σ = population standard deviation

E = margin of error

Plugging in the given values, we get:

n = (1.645 * / 5)^2

Simplifying this expression, we get:

n = 43.56

Rounding up to the nearest whole number, we get:

n = 44

Therefore, a sample size of at least 44 is required to estimate the population mean with 90% confidence and a margin of error of 5, assuming the population standard deviation is approximately .

After answering the provided question, we can conclude that As a result, expression there are 98,280 different ways to choose 5 numbers from a set of 28 where order is irrelevant.

An expression in mathematics is a collection of characterizations, digits, and huge corporations that resemble a significant correlation or regimen. A real number, a flexible, or a combination of the two can be used as an expression. Mathematical operators include addition, multiplication and division, rapid spread, separation, and exponentiation. Expressions are widely used in arithmetic, mathematics, and shape. They are used in the representation of mathematical formulas, the solution of equations, and the simplification of mathematical relationships.

The combination formula gives the number of ways to choose 5 numbers from a set of 28 where order is irrelevant:

(k!(n-k)!) = nCk

where n represents the total number of items in the set (28 in this case), and k represents the number of items to be chosen (5 in this case).

When we plug in the values, we get:

\(28C5 28!/(5!(285)!) (28x27x26x25x24)/(5x4x3x2x1) = 98, 280\)

An equation to show the additional number of cases of water Mr. Brown needs is y = 24x - 3, where y = 333 bottles and x = 14.

An equation is a mathematical statement that claims that two mathematical expressions are equal.

An equation contains the equation symbol (=).

The number of bottles in his office = 17 bottles

The total number of bottles required = 350 bottles

The total number of additional bottles of water required, y = 333

1 case of water bottles = 24 bottles

The equation to show the additional cases required is y = 24x - 3, where y = 333 bottles and x = 14.

Check:

y = 24x - 3

333 = 24(14) - 3

333 = 336 - 3

333 = 333

Thus, an equation to show the additional number of cases of water Mr. Brown needs is y = 24x - 3, where y = 333 bottles and x = 14.

By using the fact that the interior angles of a triangle must add up to 180, we will see that the value of x is 15.

Here we have 3 expressions for the measures of the interior angles of a triangle.

Now, remember that the sum of the interior angles of a triangle is always equal to 180°, then we can write:

(8x - 7)° + (x + 7)° + (2x + 15)° = 180°

Ignoring the degrees and solving this for x, we get:

8x - 7 + x + 7 + 2x + 15 = 180

11x + 15 = 180

11x = 180 - 15 = 165

x = 165/11  =15
