Answer:
15.15% probability that both months (different) have less than 31 days.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Also, the order of the months is not important. For example, picking July and August is the same as picking August and July. So the combinations formula is used to solve this problem
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
There are 12 months, of which February, April, June, September and November, that is, 5 of them, have less than 31 months.
Desired outcomes:
Picking 2 months from a set of 5(those with less than 31 days). So
Total outcomes:
Picking 2 months from a set of 12(all the months). So
Probability:
15.15% probability that both months (different) have less than 31 days.
Answer:
a) 3 kilograms
b) 5.7 kilograms
Step-by-step explanation:
Z-score:
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question:
We have to find X for both values of Z.
a) z = -1.35
3 kilograms
b) z = 2.64
5.7 kilograms
Answer:
The second graph has a y-intercept and a constant rate of change.
Step-by-step explanation:
Answer:
78.5 ft²
Step-by-step explanation:
The area of a circle is given by
Area = πr²
where r is the radius = given as 5 ft
π = 3.14
substituting the values into the equation, we get
Area
= πr²
= (3.14) (5²)
= 78.5 ft²
The answer to your question is 54 because you have to bring over 2 to 3 and it would be 1x then bring over 52 and add it to 2 = 54
