Answer:
On Tuesday 8 adult tickets and 12 child tickets were sold.
Step-by-step explanation:
Since the movie theater sells adult tickets for $ 10 and kids tickets for $ 8, and they sold $ 176 worth of tickets last Tuesday with a total of 20 ticket sales, to determine how many tickets of each type were sold, the following calculation must be performed:
10 - 8 = 2
20 x 8 = 160
176 - 160 = 16
16/2 = 8
8 x 10 + 12 x 8 = X
80 + 96 = X
176 = X
Therefore, on Tuesday 8 adult tickets and 12 child tickets were sold.
Answer:
the student should score atleast 229 to be among the top 10%.
Step-by-step explanation:
in terms of the normal distribution, and if the table that you're using calculates the area of the normal distribution from the mean to a point x, only then what we are actually finding the value 'x' at which the z-score is at 40% (the rest 50% is already skipped by the table)
after finding the the value at this z-score, we can find the value of x at which the score is in the top 10% range.
we can find the z-score either using a normal distribution table or calculator. (but be sure what area is it calculating)
looking at the table the closest value we can find is, 0.4015 at z = 1.29 ((it is above 40% because we want to be in the top 10% range)
the student should score atleast 229 to be among the top 10%.
Answer:
In geometry, a hypotenuse is the longest side of a right-angled triangle, the side opposite the right angle. The length of the hypotenuse can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides.
