Step-by-step explanation:

[tex]20 + (y - 10) + 4y \\20 + y -10 + 4y \\20 - 10 + y + 4y \\10 + 5y[/tex]

The simplification form of the expression 20 + (y - 10) + 4y is 5y + 10 after adding like terms.

It is defined as the combination of constants and variables with mathematical operators.

It is given that:

The linear expression is:

= 20 + (y - 10) + 4y

As we know, the linear expression can be defined as the relation between two variables, if we plot the graph of the linear expression we will get a straight line.

If in the linear expression, one variable is present, then the expression is known as the linear expression in one variable.

After simplifcation:

Adding like terms:

= 5y + 10

Thus, the simplification form of the expression 20 + (y - 10) + 4y is 5y + 10 after adding like terms.

Answer:

15p

Step-by-step explanation:

Let's interpret the question bit by bit

Salvador wrote 15 letters to friends each month

=> 15 letters = 1 month

For p months in a row

let the total number of letters for p months be x

=> x letters = p months

Bringing the two statements together gives;

15 letters = 1 month

x letters = p months

Now, let's solve for x by cross-multiplying the above

x letters * 1 month = 15 letters * p months

x = [tex]\frac{15 letters * p months}{1 month}[/tex]

x = 15p letters

Therefore, Salvador wrote a total of 15p letters for the p months.

Answer:

a) P(x) = 0.67

b)  P(y) = 0.67

c) P(x=4) = 0.3325

d) P( x = 0 ) = 0.0039

e) The fact that the rise and fall of the stock market relies on market sentiments violates independence used in Binomial distribution and the years are independent

Step-by-step explanation:

A) The probability that the stock market will rise next year = P(x) = 0.67

assuming next year to be X

B) Probability that the stock market will rise the year after next year

= P(y) = 0.67 and this is because the probability is independent of that of the previous years

C) Probability that the stock market will rise in four of the next five years

= P(x=4) = 0.3325

D) probability that the stock market will rise in none of the next five years

= P( x = 0 ) = 0.0039

E) The fact that the rise and fall of the stock market relies on market sentiments violates independence used in Binomial distribution and the years are independent

The probability that the stock market will rise next year = P(x) = 0.65.

The probability that the stock market will rise the year after next is p(y) = 0.65.

The probability that the stock market will rise in four of the next five years is 0.00325.

The probability that the stock market will rise in none of the next five years is 0.0039.

Independent events and probability can be defined as those occurrences that are not dependent on any specific event.

Between 1896—when the Dow Jones index was created— and 2012, the index rose in 65% of the years.

Based on this information, and assuming a binomial distribution.

1. What do you think is the probability that the stock market will rise next year?

The probability that the stock market will rise next year = P(x) = 0.65.

2. What do you think is the probability that the stock market will rise the year after next?

The probability that the stock market will rise the year after next is p(y) = 0.65.

3.  What do you think is the probability that the stock market will rise in four of the next five years?

[tex]\rm P(x=4) =0.00325[/tex]

The probability that the stock market will rise in four of the next five years is 0.00325.

4.  What do you think is the probability that the stock market will rise in none of the next five years?

The probability that the stock market will rise in none of the next five years is 0.0039.

5. What assumption of the binomial distribution might not be valid?

Independent events and probability can be defined as those occurrences that are not dependent on any specific event.

Answer:

x=3

Step-by-step explanation:

1) 10x+1-1 = 12x-5-1, this becomes a new equation

Equation: 10x = 12x-6

2) 10x-12x = 12x-12x-6, this become a new equation

Equation: -2x = -6

3) Divide both sides by -2: -2x/2 = -6/2

Answer:

Step-by-step explanation:

Here, "co" means "shared."  Two lines are coplanar if both lie in the same plane (in which case there are three possibilities:  the lines intersect in one point, the lines coincide (are one and the same), or the lines never intersect (in which case we call them "parallel."

Suppose we take a look at a three-dimensional space with perpendicular x-, y- and z-axes.  If we let one of these three variables be a constant, then the resulting area is a plane (with two-dimenions).  if we held z constant, then the plane would be the xy plane, and any two lines lying entirely in this plane are deemed to be "coplanar:"  they lie in the same plane.

Answer:

x=17 degrees

Step-by-step explanation:

Denote the sum by S. So

S = 5 + 11 + 17 + 23 + ... + 83

There's a constant difference of 6 between consecutive terms in S, so the 3 terms before 83 are 77, 71, and 65. So

S = 5 + 11 + 17 + 23 + ... + 65 + 71 + 77 + 83

Gauss's approach involves inverting the sum:

S = 83 + 77 + 71 + 65 + ... + 23 + 17 + 11 + 5

If we add terms in the same position in the sums, we get

2S = (5 + 83) + (11 + 77) + ... + (77 + 11) + (83 + 5)

and we notice that each grouped term on the right gives a total of 88. So the right side consists of several copies n of 88, which means

2S = 88n

and dividing both sides by 2 gives

S = 44n

Now it's a matter of determining how many copies get added. The terms in the sum form an arithmetic progression that follows the pattern

11 = 5 + 6

17 = 5 + 2*6

23 = 5 + 3*6

and so on, up to

83 = 5 + 13*6

so n = 13, which means the sum is S = 44*13 = 572.

Answer:

y= - 1/3x + 3

Slope =(y2−y1)/(x2−x1)

                 (2−3)/(3−0)

                      −1/3

Slope is negative 1/3

Now look on the graph where the line goes through 0,3

Answer:

Step-by-step explanation:

From the given information,

Suppose

X represents the Desktop computer

Y represents the DVD Player

Z represents the Two Cars

Given that:

n(X)=275

n(Y)=455

n(Z)=405

n(XUY)=145

n(YUZ)=195

n(XUZ)=110

n((XUYUZ))=265

n(X ∩ Y ∩ Z) = 1000-265

n(X ∩ Y ∩ Z) = 735

n(X ∪ Y) = n(X)+n(Y)−n(X ∩ Y)

145 = 275+455 - n(X ∩ Y)

n(X ∩ Y) = 585

n(Y ∪ Z) = n(Y) + n(Z) − n(Y ∩ Z)

195 = 455+405-n(Y ∩ Z)

n(Y ∩ Z) = 665

n(X ∪ Z) = n(X) + n(Z) − n(X ∩ Z)

110 = 275+405-n(X ∩ Z)

n(X ∩ Z) = 570

a. n(X ∪ Y ∪ Z) = n(X) + n(Y) + n(Z) − n(X ∩ Y) − n(Y ∩ Z) − n(X ∩ Z) + n(X ∩ Y ∩ Z)

n(X ∪ Y ∪ Z) = 275+455+405-585-665-570+735

n(X ∪ Y ∪ Z) = 50

c. n(X ∪ Y ∪ C') = n(X ∪ Y)-n(X ∪ Y ∪ Z)

n(X ∪ Y ∪ C') = 145-50

n(X ∪ Y ∪ C') = 95

Answer:4 millimeters

Step-by-step explanation:

If the volume of a cube is  1 cubic millimeter, the side length of the cube is 1 millimeter.

A cube is simply a regular solid shape with six square faces.

The volume of a cube is expressed as;

V = a³

Where a is the length of its sides.

Given that;

V = a³

1mm³ = a³

a = √(1mm³)

a = 1mm

Therefore, if the volume of a cube is  1 cubic millimeter, the side length of the cube is 1 millimeter.
