1. 10 or 10 to the first power
2. 10000 or 10 to the fourth power
3. 100 or 10 to the second power
4. 1000 or 10 to the third power
The correct answer for this question would be options A and C. The values that have three significant figures are 1.04 and 0.0760. Based on this answer, this rule applies to this: <span>Any zeros between two </span>significant digits<span> are </span><span>significant which explains why option A is qualified. And in number 0.0760, the 0.0 before 7 is not considered significant at all. Hope this explanation helps.</span>
Answer:
Step-by-step explanation:
4x - 3/2 - 5 - 2x/3 - 3x - 4/3 = 5
Give all terms least common denominator of 6:
4x(6/6) - 3/2(3/3) - 5(6/6) - 2x/3(2/2) - 3x( 6/6)- 4/3(2/2) = 5(6/6)
24x/6 - 9/6 - 30/6 - 4x/6 - 18x/6 - 8/6 = 30/6
Combine x terms and numerical terms:
2x/6 - 47/6 = 30/6
2x/6 = 77/6 (Add 47/6)
2x = 77 (Multiply both sides by 6)
x = 77/2 = 38.5
Answer:
47%
Step-by-step explanation:
we are required to find the probability to randomly select from the union of those who own a smartphone only and those who own a smartphone and computer.
an addition of the subsets cover the entire set.
6 + 15 + 26 + 32 + 21 = 100%
let
p(A)= probability of smartphone only
p(B) = probability of smartphone and computer
p(A U B) = P(A) + P(B)
= 15% + 32%
= 47%

One in 1200 are not particularly good odds. On the other hand, winning the lotto is 1 chance in 13,000,000 which if you've ever played the lotto you know that those odds are good enough to insure that if you played for the rest of your life and you are 18 not expect to live to 80 and you have 104 [given 2 draw a week] chances of winning per year, it likely won't happen. One in 1200 is better but still not good, especially with only 1 draw.

As a fraction her probability of winning is 1/2000 which is 0.000833333 as a decimal. You can put that in as

Sample Space = {1,2,3,4 .... 1198,1199,1200}
The outcome depends on sophies number. Either 1 number can be chosen or all of them can.
