Depends on your foot size. I’d go with the 8 as when you hike etc your feet can “swell” some.

The first step in solving 3.17 t - 2.431 = 5.06 is to divide both sides of the equation by 3.17. TrueFalse

Pavlova-9 [17]

Answer:

False

Step-by-step explanation:

$3.17t - 2.431 = 5.06 \\ 3.17t = 5.06 + 2.431 \\ 3.17t = 7.491 \\ \frac{3.17t}{3.17} = \frac{7.491}{3.17} \\ t = 2.363$

Is the following relation a function?

aleksklad [387]

Hello from MrBillDoesMath!

Answer:

Yes.

Discussion:

There appears to be a functional relationship based on the data gives. In particular, each value of "x" has a defined (dependent) value of "y"

First, decide whether the distribution is a discrete probability distribution, then select the reason for making this decision.

Lyrx [107]

It is not a <u>probability distribution</u>, as the sum of the probabilities is more than 1, thus, the correct option is No, considering that:

c) Since the sum of the probabilities is not equal to 1.

-----------------------------------------

For the sequence $(x, P(X = x))$ representing a probability distribution, it is needed that:

All probabilities are between 0 and 1, that is, for all values of x, $0 \leq P(X = x) \leq 1$ .
The sum of all probabilities is 1, that is: $\sum_{i = 1}^n P(x_i) = 1$

In this problem, the sum of the probabilities is:

$\sum_{i = 1}^n P(x_i) = 0.39 + 0.69 + 0.12 = 1.20$

<u>Sum is not 1,</u> thus it is not a probability distribution, and the correct option is:

c) Since the sum of the probabilities is not equal to 1.

Suppose that, in some distant part of the universe, there is a star with four orbiting planets . One planet makes a trip around

WINSTONCH [101]

Answer: 90 Earth years.

Step-by-step explanation:

Analizing the information provided in the exercise, you need to find the Least Common Multiple (LCM) of the given numbers.

You can follow these steps:

1. You must descompose 6, 9, 15 and 18 into their prime factors:

$6=2*3\\\\9=3*3=3^2\\\\15=3*5\\\\18=2*3*3=2*3^2$

2. Finally, you need to choose the commons and non commons with their greatest exponents and multiply them. Then you get:

$L.C.M=2*3^2*5=2*9*5\\\\L.C.M=90$

Therefore, it will take 90 Earth years for them to all line up.

Lebron James has 30,473 points, and adds 8,200 each year. Steph Curry has 14,403 points, and adds 9,807 each season. When will L

riadik2000 [5.3K]

Answer: it will take 10 years for both of them to have the same points.

Step-by-step explanation:

Let x represent the number of years that it will take Lebron James and Steph Curry have the same number of points.

Lebron James has 30,473 points, and adds 8,200 each year. This means that in x years, the total number of points that Lebron James would have is

30473 + 8200x

Steph Curry has 14,403 points, and adds 9,807 each season. This means that in x years, the total number of points that Steph Curry would have is

14403 + 9807x

For them to have the same points, the number of years would be

30473 + 8200x = 14403 + 9807x

9807x - 8200x = 30473 - 14403

1607x = 16070

x = 16070/1607

x = 10
