Answer:
30.5 feet / minute
Step-by-step explanation:
Rate of descent is the same as speed (of falling). The formula for speed is distance / time = speed
First, find how much it fell.
4595 - 3131 = 1464 feet
Divide the distance by the time.
1464 feet / 48 minutes = 30.5 feet / minute

A total of 190 people attended the opening night of a school
musical. Student tickets cost $4.50 each while general
admission tickets cost $6 each. If total sales were $996, how
many general admission tickets were sold?
Answers
Answer:
94
Step-by-step explanation:
x=student tickets y=general admission
We can write the two following equations
x+y=190
4.5x+6y=996
I am going to solve this through substitution
We first need to get a variable by itself
x+y=190
x-190= -y
-x+190=y
We can plug this value in for y into the second equation
4.5x+6(-x+190)=996
4.5x-6x+1140=996
-1.5x= -144
x=96
Now that we know that x=96 we can plug this value into any of the two beginning equations and solve for y
96+y=190
y=94

O C. 16
Answers
Answer:
(E) 3(sq rt 2)
Step-by-step explanation:
the figure is a square so all four sides are equal and has 90 degree corners.
the diagonal has the value of 6 so:
6^2=s^2+s^2
36=2s^2
s^2=18 or sq rt 18 which would be 3(sq rt 2)
Which choice shows three lengths that cannot be the lengths of the three sides of a triangle?
Answers
Answer:
The right answer is B.
Step-by-step explanation:
To be sure if three sides could be used to form a triangle, you need to remember that two sides of a triangle added together is always greater than the final side. B is the only selection that does not work for the law, 3 + 5 = 8 which is smaller than 10, so the corrct answer is B.

A basketball coach kept stats for his team in free throw percentage and steals (among others). At the last game, Erin's free throw percentage was 79% and she had 4 steals. The team averaged 87% from the free throw line with a standard deviation of 12 and they averaged 7 steals with a standard deviation of 3. In which category did Erin do better compared with her team
Answers
Answer:
Due to the higher z-score, she did better in the free throw category.
Step-by-step explanation:
Z-score:
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
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:
She did better in the category that she had the higher z-score:
Free-throws:
Her free throw percentage was 79%, which means that [tex]X = 79[/tex]
The team averaged 87% from the free throw line with a standard deviation of 12, which means that [tex]\mu = 87, \sigma = 12[/tex]. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{79 - 87}{12}[/tex]
[tex]Z = -0.67[/tex]
Steals:
She had 4 steals, which means that [tex]X = 4[/tex]
Averaged 7 steals with a standard deviation of 3, which means that [tex]\mu = 7, \sigma = 3[/tex]. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{4 - 7}{3}[/tex]
[tex]Z = -1[/tex]
Due to the higher z-score, she did better in the free throw category.

WILL MARK BRAINLYIST what are the values of X,Y, and z
Answers
Answer:
x=111, y=36, z=76
Step-by-step explanation:
Therefore x is 111 degrees
To find y, we will use the triangle method. We know that a triangle adds to 180, and so do two adjacent angles on a straight line.
180-66 = 114
180 - 114 - 30 = y
Therefore y is 36 degrees.
Same principles with z.
180- 119 = 61
180 - 61 - 43 = z
Therefore, z is 76 degrees.
Final:
x = 111
y = 36
z = 76

"5 more" simply means addition
So if you were to put all that together as a numerical expression it would be
(12x8) + 5
