Answer:

B. \frac{14}{625}

Step-by-step explanation:

Total paper in the hat:

2 blue + 6 red + 10 yellow + 7 purple = 25 total pieces of paper

P(AB) = 7 / 25 x 2 / 25

A is the probability of pulling a purple paper

B is the probability of pulling a blue paper

Answer:

14/625

Step-by-step explanation:

probability = favorable outcomes/total number of outcomes

First find the probability of drawing a purple piece of paper.

There are 7 pieces of purple paper.

Add all the amounts of colored paper together to get the total number of outcomes.

2 + 6 + 10 + 7 = 25

The probability of drawing purple is 7/25

Now find the probability of drawing  blue. There are 2 blue pieces of paper. Since he replaces the purple paper the total stays at 25.

The probability of drawing blue is 2/25

This is a compound probability problem, so multiply the two probabilities together.

7/25 x 2/25

14/625

In circle A, ∠BAE ≅ ∠DAE.
kirza4 [7]

The image of circle A is missing, so i have attached it;

Answer:

x = 17

Step-by-step explanation:

In Δs EAB and EAD

We are told that;

∠BAE ≅ ∠DAE

AB = AD = AE

Now,

The Two triangles have two corresponding equal sides and the angles between them are equal, thus, we can say that the two triangles are congruent by SAS (Side Angle Side) postulate of congruence

By using the result of congruence, we can say that;

EB ≅ ED

We are given that;

EB = 3x - 24 and ED = x + 10

Thus,

3x - 24 = x + 10

∴ 3 x - 24 = x + 10

Add 24 to both sides to give;

3x = x + 34

Subtract x from both sides to give;

2x = 34

Divide both sides by 2 to give;

x = 17

A coin is tossed two times. The set of outcomes is
Jlenok [28]

Answer:

Step-by-step explanation:

Each probability can be written as y/4, since there are four different possible outcomes.  Also, it's worth noting that if you add the three  up they will equal 4/4 or 1.

Put super simply, of HH, HT, TH, TT how many have zero Hs, how many have 1 H and how many have 2 Hs?  These are the answers to a, b and x respectively.

A medical study investigated the effect of calcium and vitamin supplements on the risk of older Americans for broken bones. A to
Korolek [52]

Answer:

Fraction of older Americans who were included in the study and suffered broken bones during the three-year period = (37/389) = 0.0951

Step-by-step explanation:

The fraction of older Americans who were included in the study and suffered broken bones during the three-year period?

This fraction = (Number of older Americans who suffered broken bones recorded during the three year period of the study)/(Total number of older Americans involved in the study)

Number of older Americans who suffered broken bones recorded during the three year period of the study = (11 from those that took the additional supplements) + (26 from those that did not take additional supplements) = 11 + 26 = 37

Total number of older Americans involved in the study = 389

Fraction of older Americans who were included in the study and suffered broken bones during the three-year period = (37/389) = 0.0951
