So there are 8 total cards, so you need to make your fraction out of 8. and there are 5 blue cards, so the probability of drawing one blue card is 5/8. but because you are doing a second draw, and NOT replacing the card you pulled the first time, you need to multiply 5/8 (the probability of drawing one blue card) and 4/7 (the second drawing).
5/8•4/7=5/14 which means the probability of drawing 2 blue cards in a row without replacing the first card is 5/14

Step-by-step explanation:

Description of the assumed shape:

A rectangle 2 x 8 superimposed on a semi-circle of radius 4.

Perimeter:

P = 2+8+2+(4)(pi) = 12+4pi

Area :

A = 2*8 +(pi)4^2/2 = 16 + 8pi

Dr. Brown did 6 experiments at 7AM. Dr. Rachal did 8 experiments at 6PM. They both had 564 tools each. Dr. Brown used 386 and Dr

devlian [24]

Answer:

Step-by-step explanation:

Total number of tools for both = 564.

Dr Brown used 386 tools for 6 experiments.

average number of tools per experiment used by Dr Brown = $\frac{386}{6}$

= 64 $\frac{1}{3}$

Dr Rachal used 236 tools for 8 experiments.

average number of tools per experiment used by Dr Rachal = $\frac{236}{8}$

= 29 $\frac{1}{2}$

i. The number of more experiment that can be done by Dr Brown = (564 - 386) ÷ (64 $\frac{1}{3}$ )

= 2.7668

Dr Brown can do two more experiments.

The number of more experiments that can be done by Dr Rachal = (564 - 236) ÷ (29 $\frac{1}{2}$ )

= 11.1186

Dr Rachal can do 11 more experiments.

ii. Number of tools left after Dr Brown's experiments = 564 - 386

= 178

Number of tools left after Dr Rachal's experiments = 564 - 236

= 328
