Well, 7% of 450 is 31.5. The error can go either way (too much or too little) so 450 - 31.5 = 418.5. We also do 450 + 31.5 = 481.5. The statement would be 

Book mass = >418.5 and <481.5.

(This could be wrong, I haven't done this much before.)

According to the general equation for conditional probability, if P(A n B) = 3/10 and P(B)= 2/5 what is p(alb)
Natali5045456 [20]

Answer:

P(A given B) = 3/4

Step-by-step explanation:

As we know that it is conditional probability, where the probability of an event depends on the event that has certain probability of occurrence.

The formula for conditional probability is:

P(A given B) = P(A ∩B) / P(B)

Where a and B are events. The probability of event B is known and we also know probability of A∩B

So, putting the values in the formula:

P(A\ given\ B) = \frac{P(A and B)}{P(B)}\\= \frac{\frac{3}{10} }{\frac{2}{5} } \\=\frac{3}{10} *\frac{5}{2}\\=\frac{3}{4}

So, the probability of A given B is 3/4 ..

Nataliya [291]

Answer:

2.5 inches

Step-by-step explanation:

1 feet = 12 inches

The length is 16 ft x 12 = 192 inches

The length was scales by an unknown measure which i would represent with x . The equation is as follows

192 inches x a = 4 feet

a = 48

The kitchen was scaled by 48

10 x 12 = 120 inches

120/48 = 2.5 inches
