Answer:

3/4 or 75%

Step-by-step explanation:

There are twelve possible outcomes. (4 green for each of the three orange).

The only combinations that add up to six or more are 2&4, 3&3 and 3&4.

That’s 3 out of 12.  So 9 out of 12 combinations will add up to less than 6.

Answer: hello your question is incomplete below is the complete question

Let X and Y be two independent standard normal random variables, i.e., each follows the distribution N (0, 1). Now, define two new random variables as Z = 11 - X + X²Y, W = 3-Y. find cov ( Z, W )

answer : Cov ( Z, W ) = -1

Step-by-step explanation:

Z = 11 - X + X²Y

w = 3 - Y

Cov ( Z, W ) = Cov ( 11 - x + x^2 Y , 3 - Y )

  = Cov ( 11, 3 ) - Cov ( 11, Y ) - Cov(x,3) + cov (x,y) + cov(x^2y, 3) -cov (x^2y, y )

attached below is the remaining part of the detailed solution

hence

Cov ( Z, W ) = -1

Answer:

y=-2x-1

Step-by-step explanation:

Your goal from Standard form to slope intercept form is to have the x on the right side of the equal sign. All you have to do is subtract 2x from both sides and you end up with y= -2x-1

Answer:

15 weeks

Step-by-step explanation:

I just answered this one not too long ago

It will take 15 weeks for Emanuel to lose at most 251 pounds.

An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values.

For example, 3x + 5 = 15.

Given that, Emanuel is trying to lose weight, he starts 2017 weighing 296 pounds.

If he plans to burn enough calories to lose 3 pounds per week,

We need to find that how many weeks will pass before Emanuel is at most 251 pounds,

So, let the number of weeks be x,

We will use here the concept of equations solving,

So, establishing the equations,

296 - 3x = 251

296 - 251 = 3x

45 = 3x

x = 15

Hence, it will take 15 weeks for Emanuel to lose at most 251 pounds.

Answer:

Rounded to the nearest cent, over 5 years she will earn $ 916.89.

Step-by-step explanation:

Since Tabitha found an annuity that pays 7.0% annual interest, compounded semiannually, and she decided to invest $ 650 semiannually in this annuity for 5 years, to determine how much interest she will earn during the 5 years the following calculation must be performed:

650 x (1 + 0.07 / 2) ^ 5x2 = X

650 x (1 + 0.035) ^ 10 = X

650 x 1,035 ^ 10 = X

916,889 = X

Thus, rounded to the nearest cent, over 5 years she will earn $ 916.89.

Answer: 1125.41

Step-by-step explanation:

First, let’s find out how much is in the account after 5 years. We will use the savings annuity formula

A(t)=d((1+r/n)n⋅t−1)r/n

to find the value of A(5). We know that r=0.07, d=$650, n=2 compounding periods per year and, t=5 years. Substitute these values into the formula.

A(5)=$650 ((1+0.07/2)5⋅2−1)/(0.07/2)

Simplifying gives

A(5)=$650 ((1.035)10−1)/(0.035),

thus

A(5)=$7,625.41.

The sum of all deposits D5 is given by 5⋅2⋅$650=$6,500. Now, substitute these numbers into

A(5)=D5+I5

and solve for I5. This gives

$7,625.41=$6,500+I5,

yielding the total interest paid as $1,125.41. Enter 1125.41 as the answer.

Answer:

Step-by-step explanation:

When calculations are repetitive, I like to let a calculator or spreadsheet do them. Here we have used the formula for the base area:

  B = πr² = 3.14×r²

In the second figure, the radius is half the diameter, so is 5 units.

The table in the attachment lists the base area B, the height h (from the figures), and the volume V. These are the values that you need to drag and drop to the boxes in your problem.

Since the area of the figure changed by a factor of 25, a factor by which the dimensions of the pentagon were multiplied include the following: C. 5.

In Geometry and Mathematics, a scale factor simply refers to the ratio of two corresponding side lengths in two similar geometric figures such as pentagons, which can be used to either horizontally or vertically enlarge (increase) or reduce (decrease or compress) a function that represents their size.

In Geometry, the scale factor of the dimensions of a geometric figure can be calculated by using the following formula:

(Scale factor of dimensions)² = Scale factor of area

(Scale factor of dimensions)² = 25

Scale factor of dimensions = √25 = 5
