1.04*10^9=1,040,000,000 by moving the decimal 9 spots to the right.
One million is 1.000,000, 100 million is 100,000,000, 1 billion is 1,000,000,000, and 10 billion is 10,000,000,000. Since this has the same number of digits as 1 billion and is closer to 1 billion than 10 billion due to that the second digit is lower than 5, our answer is C
Answer:
y = 35
Step-by-step explanation:
Step-by-step explanation:
using elimination method because this is a simultaneous equation
3×x+6×y=111
x+y=27
1×[3x+6y=111]
3×[x+y=27]
3x+6y=111—equation 1
3x+3y=81—equation 2
substrate equation 1 from equation 2
3y=30
divide both sides by 3
y=10
substitute 10 for y in equation 1
3x+6y=111
3x+6(10)=111
3x+60=111
3x=111-60
3x=51
divide both sides by 3
x=17
Answer:
10^-5
10^-5 = 1/100,000
Step-by-step explanation:
Answer:
a: no the sample size is too small
b: Yes, the distribution is normal with a mean of 40 and standard deviation of 12
Step-by-step explanation:
a: If n < 30, we need to know that the sample is normally distributed or else we can't determine anything. When sample sized get very large, they usually resemble normally distributed data sets so we can still make conjectures even if the data isn't officially normally distributed
b: The question tells us that the sample is normally distributed, so even though n < 30, we can still make conjectures about the population
