Answer:
Each child will get 1/4 of a pie
Step-by-step explanation:
Answer:
g < 14. Draw an open point on the number line and an arrow in the left direction.
Step-by-step explanation:
Solve the inequality like an equation using inverse operations. If you divide or multiply by a negative be sure to flip the sign.
-7 > g -21
-7 + 21 > g
14 > g
Graph the inequality by plotting an open circle on the value 14 and drawing an arrow in the the left direction for values less than 14 or g < 14.
Since area is length times width we just have to divide the area by the length
15 3/4 divided by 5 1/4 which equals three
the width of the table is 3
Answer:
And we can find this probability on this way:
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problm
Let X the random variable that represent the scores on an exam of a population, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability on this way:
