let l = lance, and a = alex.
so: l + a = 70
and l = 4a
Putting the value for l in the first equation:
4a +a = 70
5a = 70
a = 14.
So Alex has 14 pencils. And Lance has (70-14) 56 pencils.
And if each child gets half of Alex' pencils, then each child will have 7 pencils.
When the population mean and standard deviation are known, you use the standard normal distribution
<h3>How to determine the distribution?</h3>
There are several probability distributions; these include
- Normal distribution
- Poisson distribution
- Chi square distribution
- Binomial distribution
- Etc
Of all these distribution, only the standard normal distribution can be used when the population mean and standard deviation are known,
Note that it is also referred to as the z-distribution

2/3 = 6/9
and
1/2 = 4/8
Answer:
probability of picking the winning combination
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Since the order is not important, the combinations formula is used to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
Desired outcomes:
The correct five numbers from a set of 5. So
Total outcomes:
Five numbers from a set of 35. So
Probability:
probability of picking the winning combination
Answer:
{Rounded to the nearest Hundredths place}
1) Mercury= 170.55
2) Venus= 277.86
3) Earth= 389.62
4) Mars= 401.29
Explanation:
Mercury: 3.3022 x 10^19= 170.549894825 which rounds to 170.55
Earth: 5.9722 x 10^24= 389.618945662 which rounds to 389.62
Venus: 4.8675 x 10^21= 277.855972801 which rounds to 277.86
Mars: 6.4185 x 10^23= 401.287714067 which rounds to 401.29
•So smallest to largest would be• 170.55, 277.86, 389.62, and 401.29
