Suppose that 71% of the surface of the Earth is covered in water, and a random number generator uses latitude and longitude to select a random location on the Earth. If 6 locations are generated, what is the probability that at least 1 of those locations is over land?

Answers

Answer 1

Answer:

.00059 or .0006

Step-by-step explanation:

You are trying to find what won't be in the water because there are many combinations so you use a complement formula.

1-0.79=0.29

Use the left over percentage in an equation to determine the probability.

[tex]1-(0.29)^6=0.000594823[/tex]

The exponent 6 comes from the number of locations.

The new coordinates after rotation will be (-7, 6).

What is mean by Rotation of a Point in X - Y plane?

A rotation is a transformation in a plane that turns every point of a preimage through a specified angle and direction about a fixed point.

We have to given that;

A Point on a xy - plane as (6, 7) which is rotated by 90° counter clockwise about the origin.

Now, According to the question, we have;

A point with coordinates = (6, 7)

We know that, Any point (say A[x, y]) when rotated 90° counter clockwise about the origin, then its new coordinates become A'(-y, x).

Hence, By Using this rule, the coordinates of the point after rotation of point by 90° counter clockwise about the origin will be;

⇒ (-7, 6).

Hence, The new coordinates = (-7, 6).

They will spend less at the sunny side hotel

Step-by-step explanation:

The attachment completes the question.

From the question, we understand that there are 4 individuals involved.

Mr. Preston (1)Mrs. Preston (1)The children (2)

And they will spend one night

First, we need to calculate the expenses in Traveler's hotel.

[tex]Rate = \$107.10[/tex] (for 3 people)

[tex]Additional\ Person = \$21.55[/tex] (for 1 person)

[tex]Breakfast = \$8.75 * 4[/tex] (for 4 people)

[tex]Tax = \$16.85[/tex]

Total Expenses

[tex]Total = \$107.10 + \$21.55 + \$8.75* 4 + \$16.85[/tex]

[tex]Total = \$107.10 + \$21.55 + \$35.00 + \$16.85[/tex]

[tex]Total = \$108.50[/tex]

For Sunny Side hotel:

[tex]Rate = \$152.95[/tex] (for 4 people)

[tex]Tax = \$21.34[/tex]

Total Expenses:

[tex]Total = \$152.95 + \$21.34[/tex]

[tex]Total = \$174.29[/tex]

By comparison, they will spend less at the sunny side hotel.

Consider p(x)=3x^3+ax+5a, a is an element of the integers.
The polynomial p(x) leaves a remainder of -7 when divided by (x-a). Show that only one value of a satisfies the above condition and state it’s value.

Answers

By the remainder theorem,

p(a) = 3a³ + a² + 5a = -7

so that

3a³ + a² + 5a + 7 = 0

Since you know a is an integer, you can try to factorize this, or use the rational root theorem to generate a list of potential rational roots, and from there you'd select the integer roots. The rational ones are of the form m/n, where m divides the constant term 7 and n divides the leading coefficient 3. They are

a = ± 1 or ± 1/3 or ± 7 or ±7/3

so there are 4 integer candidates,

a = -1 or 1 or -7 or 7

Check the value of f(a) = 3a³ + a² + 5a + 7 at each of these:

a = -1   →   f(a) = 0

a = 1   →   f(a) = 16

a = -7   →   f(a) = -1008

a = 7   →   f(a) = 1120

and only a = -1 is a root of 3a³ + a² + 5a + 7, so that's your answer. In fact,

3a³ + a² + 5a + 7 = (a + 1) (3a² - 2a + 7)

How does the sketch of a graph of function help describe its behavior

Answers

Answer:

The end behavior of a function f describes the behavior of the graph of the function at the "ends" of the x-axis. In other words, the end behavior of a function describes the trend of the graph if we look to the right end of the x-axis (as x approaches +∞ ) and to the left end of the x-axis (as x approaches −∞ ).

Since Tony got $5 on Monday and $5 on Tuesday, we can add them together by doing 5+5. We can add 5 and 5 together to get a total of $10 that Tony has earned. This means that it isn't a sum of 0 but a sum of 10.
