Sandy brought 64 dozen cookies to the bake sale. Alejandro brought

1 answer:

7 0

Sandy - 64 dozens = 768 single cookies.
Alejandro - 62 dozens = 744 single cookies.
Pierre - 60 dozens = 720 single cookies.

Pierre brought 720 cookies. You solve this by understanding that one dozen = 12 and multiplying 12 by the given number of dozens each student brought to find out the exact amount of single cookies. Hope this helped !

I'm stuck what is 15% of 32

Len [333]

In math, 'of' means 'multiplied by,' so 15% of 32 translates to '15% * 32.'
Now solve the equation:
x = 15% * 32
x = .15 * 32
x = 4.8

Answer:

a. 0.6899

b. 0.1642

Step-by-step explanation:

a. Given the probability of success is 0.94 for an expert and that the number of pairs, n=6:

-Each attempt is independent and therefore the probability of the events is calculated as:

$P(A \ and \B )=P(A)\times P(B)\\\\P(6)=0.94\times0.94\times0.94\times0.94\times0.94\times0.94\\\\=0.6899$

Hence, the probability of correctly identifying the 6 matches is 0.6899

b.Given the probability of success is 0.74 for a novice and that the number of pairs, n=6:

-Each attempt is independent and therefore the probability of the events is calculated as:

$P(A \ and \B )=P(A)\times P(B)\\\\P(6)=0.74\times0.74\times0.74\times0.74\times0.74\times0.74\\\\=0.1642$

#Hence, the probability of correctly identifying the 6 matches is 0.1642

*I have used the sample size of 6(due to conflicting info/question size).
