There are 10 digits from 0 to 9
When you say 4 digit number that means it can't start with zero, then
1) there are 9 ways to chose the 1st digit (excluding zero)
2) there are only 1 ways to chose the 2nd digit (only 8))
3) there are 10 ways to chose the 3rd digit
4) there are 10 ways to chose the 4th digit

TOTAL NUMBER OF WAYS: 9 x 1 x 10 x 10 = 900

Jorge ordered 22 bottles of juice. Each bottle holds 6.32 ounces of juice.
Umnica [9.8K]

Answer: On the first one its either A or D. (I think)

Step-by-step explanation:

So what I did was I multiplied 22 and 6.32 together and got 139.04 and the closest estimate to that would be 160 because 39 is closer to 60 than 20 (A) and since its not 150 the estimate would be lower than higher. (D)

Orders for a computer are summarized by the optional features that are requested. The proportion of orders with no optional feat
Scorpion4ik [409]

Answer:

(a) 71.00%

(b) 63.00%

Step-by-step explanation:

No optional features = 0.29

One feature = 0.34

Two features = 0.37

(a) The probability that an order requests at least one optional feature is 100% minus the probability of an order requesting no optional features:

P=1-0.29=0.71=71.00\%

(b) The probability that an order does not request more than one optional feature is 100% minus the probability of an order requesting two optional features:

P = 1 -0.37=0.63 = 63.00\%
