Answer:

b

Step-by-step explanation:

The average age would not change.

An observation that lies an abnormal distance from other values in a random sample from a population.

The average is the middle value of a set of numbers. It is calculated by adding the individual terms and dividing the sum with number of terms.

Outliers are stragglers — extremely high or extremely low values — in a data set that can throw off your stats.

Thus it does not effect the average age

The correct option is C

Answer:

92

Step-by-step explanation:

you must first divided both sides of the equation by 7 then it will come to the answer p=92

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:

Step-by-step explanation:

g(2) = 3(2) + 1 = 6 + 1 = 7

h(7) = 2(7) - 1 = 14 - 1 = 13

Using composite functions, it is found that:

[tex](h \circ g)(2) = 13[/tex]

The composition of functions h(x) and g(x) is given by:

[tex](h \circ g)(x) = h(g(x))[/tex]

In this problem, the functions are:

[tex]h(x) = 2x - 1[/tex]

[tex]g(x) = 3x + 1[/tex]

Then:

[tex]h(g(x)) = h(3x + 1) = 2(3x + 1) - 1 = 6x + 2 - 1 = 6x + 1[/tex]

At x = 2:

[tex](h \circ g)(2) = 6(2) + 1 = 13[/tex]

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.

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.

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

To put numbers in scientific notation, you have one (1) non-zero digit in the ones place.

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:

x=-2

Step-by-step explanation:

9.75+4.99x=9.99x+19.75

Simply Both Sides(change the order of 9.75 and 4.99x in this case)

4.99x+9.75=9.99x+19.75

Subtract 9.99x from both sides

4.99x+9.75−9.99x=9.99x+19.75−9.99x

−5x+9.75=19.75

Subtract 9.75 from both sides now

−5x+9.75−9.75=19.75−9.75

−5x=10

Divide both sides by -5 and boom

−5x/-5=10/-5

Step-by-step explanation:

hope this helps! got it right edge 2021

Here we have a problem with translations, where translations are operators that act on functions and move the whole graph of the function in some given direction.

Sadly, the options for this question are missing, so I will answer in a general way and will post a graph at the end of the answer.

We should start by defining the translation used here.

Horizontal translation:

For a general function f(x), an horizontal translation of N units is written as:

g(x) = f(x + N)

Here we have that the original function is f(x) = |x|, and the translated function is g(x) = |x + 2|

Then we have:

g(x) = f(x + 2).

We can conclude that this is a translation of 2 units to the left.
