John's average speed for the whole race would be;  12.8 kilometers per hour

The first part of the race was 14 km long, and he completed it in 1 hour.

Now, formula for speed is;

Speed = distance/time

Thus, John's speed in the first part of the race would be;

14/1 = 14km/hr

The second part was 18 km long, and he completed this part in an hour and a half. This means that his speed in the second part of the race is;

18/1.5 = 12km/hr

Average speed = Total distance/total time

Total distance for both parts of the race is;

14 + 18 = 32km

Total time for the race is;

1 + 1.5 = 2.5 hours

John's average speed for the whole race would be;

32/2.5 = 12.8 kilometers per hour

The diver was 450 feet deep in the water 10 minutes ago.

Let our D be the depth of the diver 10 minutes ago.

Since diver is pulled out at 25 ft/minute, the depth formula can be written as:

[tex]D - 25t = 200[/tex] where t is the time in minutes.

Substituting t = 10, we have:

[tex]D - 25(10) = 200\\D - 250 = 200\\D = 200 + 250\\D = 450 feet.[/tex]

Note that given the speed at which he is being pulled out, the diver was 50 feet about 10 minutes ago.

The diver is being pulled out at the rate of 25 feet per minute.

This means that after 10 minutes, he would have been pulled by a total of

25 x 10 = 250 feet.

Since the diver was 200 feet below sea level,

200-250 = -50ft.

hence 10 minutes ago, he was 50 feet below sea level.

The inequality expression p + 1.4 ≤ 0.5 is false for p = 0.1

From the question, we have the following parameters that can be used in our computation:

p + 1.4 ≤ 0.5;

p = 0.1

Substitute p = 0.1 in p+ 1.4 ≤ 0.5;

So, we have the following representation

0.1 + 1.4 ≤ 0.5;

Evaluate the like terms

This gives

1.5 ≤ 0.5;

The above inequality is false

This is because 1.5 is greater than 0.5

Hence, p + 1.4 ≤ 0.5; p = 0.1 is false

There are $20468.55 must you deposit now in order to have $25,000 in 4 years in an account getting 5% interest compounded daily.

What is compound interest?

Compound interest, also known as interest on principal and interest, is the practice of adding interest to the principal amount of a loan or deposit.

Given:

A = Final amount = $25000

P = Initial principle balance

r = interest rate = 5% = 0.05

t = Number of time of years

n = number of times interest applied per time period = 365

Since, the formula for compound interest,

[tex]A = P(1+\frac{r}{n})^n^t[/tex]

Plug the values of A, r, n and t in the above formula

[tex]25000 = P(1 + \frac{0.05}{365})^3^6^5^*^4 \\25000 = P(1.0001369863)^1^4^6^0\\25000 = P(1.2213860258)\\P = 20,468.549231702[/tex]

P ≈ 20,468.55

Hence, there are $20468.55 must you deposit now in order to have $25,000 in 4 years in an account getting 5% interest compounded daily.

Answer:

The probability of rain on both Monday and Tuesday is .08, or approximately 8%.

Step-by-step explanation:

The probability of an event occurring on two separate days (such as rain on Monday and Tuesday) is calculated by multiplying the probabilities of the two events occurring separately. In this case, the probability of rain on both Monday and Tuesday is given by:

Probability of rain on Monday * Probability of rain on Tuesday = .1 * .8 = .08

Therefore, the probability of rain on both Monday and Tuesday is .08, or approximately 8%.

It's important to note that this probability assumes that the likelihood of rain on each day is independent of the other day. In other words, the probability of rain on Tuesday does not depend on whether or not it rained on Monday. If this is not the case, the probability of rain on both days may be different.

Step-by-step explanation:

The probability that an individual will take far longer than 21 days to complete it is 0.12.

In the descriptive analysis, the standard deviation is the amount of scatter or dispersal of the pieces of data in relation to their mean. It provides information on the distribution of values within the sample data and serves as a gauge for how widely apart the measured values are from the mean.

As per the information available in the question,

Meantime, μ = 14 days

Standard deviation, ρ = 6 days

Assume the time to pass the kidney stone be x.

The probability that it will take someone more time than 21 days to complete it.

Let's find out the Z-score first,

Z-score = (x - μ)/ρ

Substitute values in above equation,

= (21 - 14)/6

Z-score = 1.166.

The probability that it will take someone more time than 21 days to complete it :

P(x > Z) = P(x > 1.16) = 0.12

The measure of one interior angle of the 45-sided polygon is (c) 172 degrees

From the question, we have the following parameters that can be used in our computation:

Shape = 45-sided polygon

Parameter to calculate = the measure of one interior angle

The sum of the interior angles is calculated using the following angle formula

The sum of the interior angles = ( n − 2 ) × 180 ∘ where is the number of sides

In this case

n = 45

Substitute the known values in the above equation, so, we have the following representation

The sum of the interior angles = (45 − 2) × 180∘

Evaluate

The sum of the interior angles = 7740∘

So, the internal angle is

Angle = 7740/45

Evaluate

Angle = 172

Hence, the angle is (c) 172 degrees

The linear equation represented in the table is:

y = (1/2)*x - 2

A general linear equation can be written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

Remember that if a line goes through two points (x₁, y₁) and (x₂, y₂) then the slope is:

a = (y₂ - y₁)/(x₂ - x₁)

Here we can use the first two points on the table (0, -2) and (2, -1), so we will get:

a = (-1 + 2)/(2 - 0) = 1/2

And because of the point (0, -2) we know that the y-intercept is -2, so we can write:

y = (1/2)*x - 2

The value of x for the given triangle is x = 86°.

What is triangle?

Three edges and three vertices make up a triangle, which is a polygon. It is among the fundamental shapes in geometry. Triangle ABC refers to a triangle with the vertices A, B, and C. In Euclidean geometry, any three points that are not collinear determine a singular triangle and a singular plane at the same time.

From the given triangle we have to find the value of x.

By triangle's property.

(x - 45)° + (x + 3)° = (x + 44)°

              2x - 42 = x + 44

                 2x -x = 44 + 42

The value of a nickel is of $0.05, while the value of a quarter is of $0.25. The total value of the coins in the jar is $12.95, hence:

What is probability?

Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.

Given that the total number of people that are taken for the event is 572.

The number of people who have eaten snack A before is 236.

The number of people who have not eaten snack A before is 336.

Probability = The number of outcomes of favorable event/ Total number of outcomes

The probability getting a person who has eaten snack A before is

= 236/ 572

= 59/143 [Divide denominator and numerator by 4]

Answer: A woman has 8 skirts, 5 blouses, and 5 pairs of shoes. This means that she has a total of 8 * 5 * 5 = <<855=200>>200 different skirt-blouse-shoe outfits that she can wear.

Step-by-step explanation: To find the number of different skirt-blouse-shoe outfits that a woman can wear, we need to find the total number of combinations of skirts, blouses, and shoes that she has. To do this, we simply multiply the number of skirts that she has by the number of blouses that she has by the number of pairs of shoes that she has. In this case, the woman has 8 skirts, 5 blouses, and 5 pairs of shoes, so the total number of combinations is 8 * 5 * 5 = 200. This means that she can wear 200 different skirt-blouse-shoe outfits.
