Answer:

Yes

Step-by-step explanation:

4 dozen cookies is 4*12 = 48.. Each cookies has 3 cookies. This requires 3*48 = 144. She has 4 jars of 40 each or 4*40 =160. So she has enough.

scZoUnD [109]

Answer:

4478 m

Step-by-step explanation:

Altitude 1= A1= Mt Whitney is at 4392 m above sea level.

Altitude 2= A2= Bombay Beach is -86

Difference in Altitude= A3=?

A3 = A1 - A2 (because A1 is mentioned first and is the greater altitude)

A3 = 4392 - (-86)

= 4392 + 86

A3 = 4478 m

aalyn [17]
Its easier to find the complement of that instead
so you find the probability of 1 and 0
The .2 in the answer is the probability of each question 1/5
  (10 C 0) x .2^0 (1-.2)^10-0=.1074
 (10 C 1) x .2^1 (1-.2)^10-1=.2684
.2684+.1074=.3758 and that's the complement
so 1 - .3758= .6242
