Answer:

Step-by-step explanation: I choose d because if you notice there are only 33 marbles in Bag F and Bag F-number of marbles is equal to                         1/3 marbles = 11/33 marbles and Bag G contains only 11 marbles which are how many marbles there are in all bags.

Answer:

The probability of randomly selecting a blue marble from bag F is 1/3

Step-by-step explanation:

Let's logically work this out:

Bag G has 33 marbles.

Bag F has 11 marbles.

Each bag is mentioned to have 11 blue marbles, so that means there is a 1/3 chance of picking a blue marble from bag F and a 1/1 (100%) chance of picking a blue marble from bag G.

A is incorrect because the chance of picking a marble from bag G (about 33%) is less than bag F (100%).

B is incorrect because the probability is 1/3, not 1/1. If it said bag F, it would be correct, however it is not so.

C is incorrect because, as mentioned before, 33% is not larger than 100%. It specifically says bag F has a greater chance, so this isn't correct.

D IS correct not only because it's the last one left, but because 11/33 (blue marbles to all marbles in the bag) is equal to 1/3 when simplified.

Sholpan [36]

Answer:

The scores are between 50 and 90

Step-by-step explanation:

When we say middle 95%, we means that this value falls between 2 standard deviations of the mean i.e

μ ± 2σ

Hence,

mean of 70 and a standard deviation of 10

μ ± 2σ

μ - 2σ

70 - (2 × 10)

= 70 - 20

= 50

μ + 2σ

= 70 + (2 × 10)

= 70 + 20

= 90

A student walked 100 meters north, then 100 meters west. how many more meters did the student walk compared to their total displ
seraphim [82]

Using Pythagorean theorem, the student walked 53.58 meters more compared to the total displacement from the starting point.

If a student walks 100 meters north, then 100 meters west, then the path he travels resembles the sides of a right triangle (see attached photo).

Using Pythagorean theorem, we can solve for the total displacement from the starting point to the end point.

c^2 = a^2 + b^2

where c is the total displacement from the starting point to the end point

a is the distance he walks up north

b is the distance he walks to the west

c^2 = 100^2 + 100^2

c^2 = 10,000 + 10,000

c^2 = 20,000

c = 141.42 meters

Comparing the total distance the student walked and the total displacement from the starting point to the end point by subtraction.

100 meters + 100 meters - 141.42 meters = 53.58 meters
