Answer:

1. She's probalaly going to use that one.

2. Her glass marble is problay going to break.

Step-by-step explanation:

She's picking random marbles right?

So we need to figure out which ones she picked out.

It says that she picked out 9 plasic marbles,

7 wooden marbles, 14 glass marbles,

and 10 wooden marbles. So she then, She put ONE

plasic marble on the table and then replaced

it with another one. Thinksmarter, And if you DID Thinksmarter,

you would know that answer one would be, she would use the other marble and probally not use the one on the table.

lets move on to answer 2. this one is very easy! sheputs a glass marble on the table and then pick/holds the medal one. therefore, the glass marble is round, so it will roll of the table and most likely break.

i hope this helps you and please mark me brainlieist

The high school took two field trips to the Newport Aquarium many many years ago. They used school buses and vans to transport a

il63 [147K]

Answer:

bus = 43

van 12

Step-by-step explanation:

This can be solved using simultaneous equations

Let v represent the number of students that a van carries

Let b represent the number of students that a bus carries

the following equations can be derived from the question

3v + 2b = 122 eqn 1

5v + 3b = 189 eqn 2

Multiply eqn 1 by 5 and eqn 2 by 3

15v + 10b = 610 eqn 3

15v + 9b = 567 eqn 4

Subtract equation 4 from 3

b = 43

Substitute for b in equation 1

3v + 2(43) = 122

solve for v

v = 12

You start driving north for 9 miles, turn right, and drive east for another 40 miles. At the end of driving, what is your straig

Vsevolod [243]

The straight line distance from the starting point is 41 miles.

<u>Explanation:</u>

Given:

Distance covered towards north, n = 9 miles

Distance covered towards east, e = 40 miles

Distance from the origin to the end, x = ?

If we imagine this, then the route forms a right angle triangle

where,

n is the height

e is the base

x is the hypotenuse

Using pythagoras theorm:

(x)² = (n)² + (e)²

(x)² = (9)² + (40)²

(x)² = 1681

x = 41 miles

Therefore, the straight line distance from the starting point is 41 miles.

Given the linear correlation coefficient r and the sample size n, determine the critical values of r and use your

Mila [183]

The critical value of r is mathematically given as r = +0.487, with no significant linear correlation. Option A.

<h3>What are the critical values of r?</h3>

Question Parameters

r = -0.868

n = 5

df = 5 - 2

df = 3

$\alpha / 2 =0.025$

Critical values $r= \pm 0.878$

Generally, there exists no linear correlation between the Critical values

as r=0.878

In conclusion, Critical values: r = +0.487, no significant linear correlation
