Answer: 20 years

Step-by-step explanation:

Let M be the sum of money invested.

Given Sum of money doubles itself in 10 years.

Then, M will become 2M in 10 years.

Now we can calculate interest for ten years as given below.

From the above calculation, M is the interest for the first 10 years.

In simple interest, interest earned will be the same every year.

So, interest earned in the next 10 years also will be M.

So it will take 20 years.

2 angles are complementary means together they = 90 Degrees.

Let the smaller angle be x

The complement = 3*x - 14  It is the larger angle.

Givens

<1 = x

<2 = 3x - 14

<1 + <2 = 90

Solution

x + 3x -14 = 90              Combine the left

4x - 14 = 90                  Add 14 to both sides

4x - 14+14 = 90 + 14     Combine

4x = 104                       Divide both sides by 4

4x/4 = 104/4

x = 26

Answer

<1 = 26

<2 = 3*26 - 14

<2 = 78 - 14

<2 = 64

This rule apply to triangles in spherical geometry If there another value that they would always sum to greater than 180 degrees.

Euclidean geometry is the study of geometrical shapes (plane and solid) and figures based on different axioms and theorems.

In spherical geometry, angles are defined between great circles, resulting in a spherical trigonometry that differs from ordinary trigonometry in many respects; for example, the sum of the interior angles of a spherical triangle exceeds 180 degrees.

Thus, this rule apply to triangles in spherical geometry If there another value that they would always sum to greater than 180 degrees.

Randall and the most money. she earned 50 cents more than Stephano did.

Step-by-step explanation:

so it's Randall makes $27.50 on his first day and $25 on a second date and and 32.50 on his third day you would add those up to get $85 in all. now Stefano gets 7.50 22.50 12.50 15.00 and 17.00 dollars , and when you add all those together he gets 84.50 and all. meaning that random made more money by .50 cents.

The margin of error is multiplied by √2.

Given that All else is equal if you cut the sample size in half and to make a statistical inference about the mean of the normally distributed population from which it was drawn ME=(z+s)/√n.

Margin of error (ME) from the mean can be calculated using the formula ME=(z+s)/√n where

z means it is the corresponding statistic of the given confidence level

s means it is the standard deviation of the sample (or of the population if it is known)

N is the sample size

As we know margin of error is proportional with inverse of √N,

If we will cut the sample size in half, the margin of error is multiplied by √2.

Hence, if sample size is cut in half then the margin of error when using the sample to make statistical inferences about the mean of the normally distributed population from which it was drawn is √2.

The probability that a five-card hand will contain a straight = 5/1274

There are 52 cards in a deck from which each 13 cards are from 4 different suits (clubs, diamonds, spades and hearts) in a game of poker.

Each 13 cards from high to low are Ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King. So a straight of five cards, i.e., five cards in unbroken numerical sequence would be got only from 10 cards in a sequence.

So the possible ways to get a single straight five from all four suits = [tex]4^5[/tex]

Now as we doesn't need all 5 cards from a single suit, we can ignore 4 ways from the above number. i.e.,  [tex]4^5-4 = 1020[/tex] ways.

Hence the possible ways to get a straight five from 10 cards from all four suits = 10 x 1020 = 10200 ways

Total number of ways to select 5 cards from 52 cards = 52C5

Thus,

The probability that a five-card hand will contain a straight = 10200 / 52C5

                                                                                                  = 5/1274                        Learn more about probability at https://brainly.com/question/5858025

Answer:

Step-by-step explanation:

Answer:

Ok, since this is not a multiple choice question, I'll tell you how I would write it.

Step-by-step explanation:

It stopped snowing for 10 to 12 hours after the storm and then started snowing again. This is because you can see that the y value (amount of snow on the ground in inches) has no change between 10 to 12 hours after the storm began.

For the second part, Think of the independent variable as the cause(its value is independent of other variables) and the dependent variable as the effect, essentially the value that depends on changes in the independent variable. In this case it tells you that the perimeter of a square depends on the length, so that means that the length is independent and the perimeter of the square is dependent. So, the dependent variable is the perimeter, because the perimeter of a square depends on the length.

A function relating these variables is K(x) = y since the dependent variable (y) depends on the independent variable (x)

Now for the last part that says So K(5) = ___ meaning if 5 ___ I don't really understand what it is asking for, since K(x) = y then K(5) would equal whatever y is when x is 5, but k(5) could also equal 5k if we were just evaluating.

Answer: Height = 5m

Step-by-step explanation: To solve the height of the triangle we can use the Area formula and substitute the values given to solve for heigh.

A = ( b * h ) / 2

17.5 = (7 * h) / 2

17.5 (*2) = 7 * h

(Remember that everything done to one side has to be done to both. We can multiply by 2 on both sides to eliminate the 2.)

35 = 7 * h

35/7 = h

5 = h

The height of the triangle equals 5.

a) The meaning of the point (t, s) = (5, 6) is that the backpacker travels a distance of 5 miles in 6 hours.

b) The equation of the relationship between the distance traveled by the backpacker and time taken is equal to s = (6 / 5) · t.

According to the image attached aside, we find that the distance traveled by the backpacker (s), in miles, is directly proportional to the time taken (t), in hours. In other words, we have the following relationship:

s ∝ t

s = k · t      (1)

Where k is the constant of proportionality, in miles per hour.

a) The meaning of the point (t, s) = (5, 6) is that the backpacker travels a distance of 5 miles in 6 hours.

b) To determine the equation of the relationship, we need to calculate the constant of proportionality. If we know that t = 5 h and s = 6 mi, then the equation of the relationship is:

6 = 5 · k

k = 6 / 5

s = (6 / 5) · t

The equation of the relationship between the distance traveled by the backpacker and time taken is equal to s = (6 / 5) · t.

The linear equation for the moose population p as a function of t the years since 1986 is P(t) = 380t + 2920.

The equations with two variables where each variable has the largest exponent order of 1 having one, zero, or an infinite number of solutions, and are referred to as linear equations in two variables. A linear equation with two variables has the conventional form ax + by + c = 0, where x and y are the variables. Additionally, the answers can be expressed as ordered pairs, like (x, y).

Linear equations have three main forms which are as follows:

We will consider x on the graph to be years since 1986 and y on the graph to be the number of Moose.

We have two points on the graph:  (6, 5200) and (11, 7100)

Using the slope formula m = (y2 - y1)/(x2 - x1), we can find the slope of this line:

m = (y2 - y1)/(x2 - x1)                

m = (7100 - 5200)/(11 - 6)          

m =  1900/5                            

m = 380                                  

Now, that we have the slope of the line, we can use the point-slope formula (y - y1) = m(x - x1) to find the equation for the line.  Here, we're using the first point, but either point will produce the same answer.

(y - y1) = m(x - x1)                                    

y - 5200 = 380(x - 6)                            

y - 5200 = 380x - 2280                            

y - 5200 + 5200 = 380x - 2280 + 5200    

y = 380x + 2920                                    

Since the equation that is being sought is supposed to be in terms of P and t, We will replace y with P and x with t.

Hence, the equation will be P(t) = 380t + 2920.

The slope of the line through (x_1, y_1) and (x_2, y_2) is:

(y_2 - y_1)/(x_2 - x_1)

Substitute (x_1, y_1) = (1, -1) and (x_2, y_2) = (-8, -7):
