The answer to that equation is 7938
One interpretation of this problem would be:
The prob. that Jamie both makes money in both bonds and stocks is
(1/20)(0.82), approximately. That comes out to 0.041. This is true onlyl if the two given events are completely independent, which is most likely not the case, because simiilar business climates affect both stocks and bonds.
Answer:
440 Rock CDs
Step-by-step explanation:
Let number of rock CDs be "r", and
number of Jazz CDs be "j"
4 times as many Rock as Jazz, so we can write:
r = 4j
Total of 550 CDs, thus we can write equation 2:
r + j = 550
Now we replace 2nd equation with 1st equation and find j first:
r + j = 550
4j + j = 550
5j = 550
j = 550/5
j = 110
Now, finding r:
r = 4j
r = 4(110)
r = 440
There are 110 Jazz CDs and 440 Rock CDs
Answer:
Bb-2=4
Step-by-step explanation:
b+4=8:is incorrect 2+4=6
2b-3=0 is incorrect 2(2)-3=1
25+24=30 also incorrect
Bb -2=4 is corrext since B(2)-2=4 is same as 2B-2=4:which is the correct equation
A reciprocal is the inverse of a number. if you are given a whole number such as 2 or 3 or 4 or 5... etc. then you flip the number by putting a 1 as the numerator. so the reciprocal of 2 is 1/2 and for 3 it is 1/3 and 4 is 1/4... and so on...
first put your decimal in fraction form
2.5 = 2 and 5/10
= 2 and 1/2
= 5/2 ---> 2/5 (0.4) is the reciprocal of 2.5
