If P(A) is 0.64, then P(A') is 0.36. P(A) is probability of occurrence of event A.

This question pertains to Probability principles. Probability is a measure of the possibility of an event occurring. Many occurrences cannot be foreseen with absolute accuracy. We can only anticipate the likelihood of an event occurring using it.

A is an occurrence in this context. A' denotes the event's complement.  

For example, if Event A is getting heads on a coin toss, then Event A' is getting tails.

This demonstrates one thing:

A ∪ A' = U, here U is the universal set.

P ( U) = 1

P (A) + P(A') = 1

0.64 + P (A') = 1

P(A') = 1 - 0.64

P (A') = 0.36

The expression of the perimeter of the triangle is  15h - 6k + 12m.

A triangle is a polygon with three sides. The sum of angles in a triangle is 180 degrees.

The perimeter of a triangle is the sum of the whole three sides of the triangle.

Therefore, let's find the perimeter of the triangle with side length (5h - 4k), (10h + 7m) and  (5m - 2k).

Therefore,

perimeter of a triangle = 5h - 4k + 10h + 7m + 5m - 2k

collect like terms

perimeter of a triangle = 5h + 10h - 4k - 2k + 7m + 5m

Using typical walkway widths to 6 ft, to calculate the area the red triangle to be 486 square feet and the area of the garden to be about 4400 square feet, rounding up.

Then it is a right triangle and side a is the altitude or height of the triangle and side b is the base.  

The measurements of the triangle are approximately in the proportion of 3, 4, 5, a typical "Pythagorean Triple" right triangle.

Estimating from rough measurements of the triangle and the dimensions of the garden as shown, the area of the garden is about 18 times the area of the red triangle.

The area of the triangle is half the area of a rectangle with the same side lengths a & b, therefore, 9 ab is a good estimate of the area of the garden.

Step-by-step explanation:

To calculate Michelle’s monthly credit card payment, we need to find the total amount she owes and then divide it by the number of months she has to pay it off.

First, we need to find the total balance on Michelle’s credit cards:

$4,380 + $1,365 + $2,480 + $5,000 = $13,225

Next, we need to find the weighted average interest rate of her credit cards. To do this, we multiply each balance by its corresponding APR and add up the results. Then we divide by the total balance:

($4,380 x 0.17) + ($1,365 x 0.19) + ($2,480 x 0.23) + ($5,000 x 0.15) = $1,038.55

$1,038.55 ÷ $13,225 = 0.0785, or 7.85%

Now we can use the total balance and the weighted average interest rate to calculate Michelle’s monthly payment using the formula for a fixed payment on a loan:

P = (r(PV)) / (1 - (1 + r)^-n)

Where:

P = monthly payment

r = monthly interest rate (as a decimal)

PV = present value of the loan

n = number of payments

r = 0.16 ÷ 12 = 0.01333 (monthly interest rate)

PV = $13,225

n = 36

P = (0.01333(13,225)) / (1 - (1 + 0.01333)^-36) = $367.36

Therefore, Michelle’s monthly credit card payment would be $367.36 if she consolidated all of her credit card debt into a single credit card with an interest rate of 16% and paid it off in 36 months. The answer is (a) $367.36.

The radian measure that is equivalent to 300° is equal to 5π/3. So, correct option is D.

To convert degrees to radians, we use the conversion factor of π/180, which means that one degree is equal to π/180 radians. Therefore, to convert 300° to radians, we multiply 300 by π/180:

300° * π/180 = 5π/3

To understand this conversion, we need to remember that radians are a unit of measurement for angles, just like degrees. However, while degrees divide a circle into 360 equal parts, radians divide a circle into 2π equal parts. One full rotation is equal to 2π radians, which is also equal to 360°.

Since 5π/3 radians is less than one full rotation, it represents an angle that is less than 360°. In fact, 5π/3 radians is equivalent to 300°, which is a well-known angle used in many contexts, such as in geometry, trigonometry, and physics.

In summary, to convert 300° to radians, we multiply it by the conversion factor π/180, which gives us the equivalent angle measure of 5π/3 radians.

So, correct option is D.

Answer:

"high" should go in the blank. A correlation coefficient of .79 indicates a pretty strong positive correlation.

Step-by-step explanation:

We know that the vertex of the parabola is at the origin, so the equation must have the form:

y = a x^2

where a is a constant.

We also know that the directrix is y = -1.5, which means that the focus is located at (0, 1.5).

Using the formula for the distance between a point (x, y) and a line ax + by + c = 0, which is given by:

d = |ax + by + c| / sqrt(a^2 + b^2)

we can find the value of a. The distance from the vertex (0, 0) to the directrix y = -1.5 is equal to the distance from the vertex to the focus (0, 1.5), so we have:

d = |y - (-1.5)| / sqrt(1^2 + 0^2) = sqrt(x^2 + (y - 1.5)^2) / sqrt(0^2 + 1^2)

Simplifying this equation, we get:

sqrt(x^2 + (y - 1.5)^2) = |y + 1.5|

Squaring both sides, we get:

x^2 + (y - 1.5)^2 = (y + 1.5)^2

Expanding and simplifying, we get:

x^2 = 3y

So the equation of the parabola with vertex at the origin and directrix y = -1.5 is:

y = (1/3)x^2

Therefore, the correct answer is: y = (1/3)x^2.

Therefore, using simple division, the price of one pen is calculated to be around $0.27.

In mathematics, division is the process of dividing an integer into equal pieces or groups. It performs multiplication in the other direction. To obtain the quotient or outcome in division, an even number has been divided by another integer, known as the divisor.

We must divide the total expense of the 12-pen pack by the quantity of pens in the box in order to figure out the price of one pen:

Price of one pen is equal to the sum of the pack's pen costs divided by the number of markers in the pack.

In this instance, we may substitute these values as we are aware that the set of 12 pens costs $3.25.

In this instance, we may enter the following values into the calculation as we are aware that the set of 12 markers costs $3.25:

One pen costs $3.25 divided by 12

Long division or using a calculator, we obtain:

One pen costs $0.27.

Consequently, the price of a pen is roughly $0.27.

The estimated cost of sending a letter that weighs 5 ounces is $9.75.

What is estimated cost  ?

Estimated cost refers to an approximate or calculated value of the cost of something. It is a value that is based on estimation, rather than being an exact or precise value.

Since the equation given is a linear equation with a slope of 0.25, we can interpret the slope as the cost per ounce of postage. This means that for every additional ounce, the cost of postage increases by $0.25.

To estimate the cost of sending a letter that weighs 5 ounces, we can use the given equation:

y = 0.25x + 8.50

where x = 5 (since the weight of the letter is 5 ounces).

Plugging in x = 5, we get:

y = 0.25(5) + 8.50

= 1.25 + 8.50

= 9.75

So the estimated cost of sending a letter that weighs 5 ounces is $9.75.

Looking at the graph provided, we can also see that the point (5, 9.75) lies on the line, which confirms our estimate.
