year, it had 504 students. What is the percent of
change in the enrollment?
explain.
Answers
Answer:
there is a 5% increase
Step-by-step explanation:
say 480=100%
4.8=1%
divide 504 by 4.8 you get 105,
so 504=105%
this is 5 more than 100 therefore 5%
7. Make a box-and-whisker plot for the data. What is the upper quartile value?
56 32 48 52 51 53 48 38 35 42 40 46 54 50
Answers
In order to draw the Box-whisker plot, we need to rewrite the data in increasing order.
42 43 47 48 51 52 56 56 58 60 62 64 65 66
Mean of the data = (42 + 43 + 47 + 48 + 51 + 52 + 56 + 56 + 58 + 60 + 62 + 64
+ 65 + 66) ÷ 14
Mean of the data = 770 ÷ 14
Mean of the data = 55
Median = (56 + 56) ÷ 2
Median = 112 ÷ 2
Median = 56
Lowest value = 42
Highest value = 66
Range = Highest value - Highest value
Range = 66 - 42
Range = 24
Lower Quartile = 25% of the data
Lower Quartile = 48
Upper Quartile = 75% of the data
Upper Quartile = 62

Answers
Answer:
x = -11
Step-by-step explanation:
Equations
The image shows a right triangle with angles 70°, 90°, and x+31.
The sum of the internal angles of a triangle is 180°, thus:
70 + 90 + x + 31 = 180
Simplifying:
191 + x = 180
Subtracting 191:
x = 180 - 191
x = -11

pls help find the amount at the end of 6 hours
Answers
Answer:
A. 7,348
Step-by-step explanation:
P = le^kt
intitial population = 500
time = 4 hrs
end population = 3,000
So we have all these variables and we need to solve for what the end population will be if we change the time to 6 hours. First, we need to find the rate of the growth(k) so we can plug it back in. The given formula shows a exponencial growth formula. (A = Pe^rt) A is end amount, P is start amount, e is a constant that you can probably find on your graphing calculator, r is the rate, and t is time.
A = Pe^rt
3,000 = 500e^r4
now we can solve for r
divide both sides by 500
6 = e^r4
now because the variable is in the exponent, we have to use a log
[tex]log_{e}(6) = 4r[/tex]
ln(6) = 4r
we can plug the log into a calculator to get
1.79 = 4r
divide both sides by 4
r = .448
now lets plug it back in
A = 500e^(.448)(6 hrs)
A = 7351.12
This is closest to answer A. 7,348

Step-by-step explanation:
Find the probability that when four numbers from 1 to 100, inclusive, are picked at random with no repetitions allowed, either all are odd, all are divisible by 3, or all are divisible by 5.
Answers
Answer:
The probability is;
0.076
Step-by-step explanation:
The count of numbers from 1 to 100 is 100
Let’s find the number of odd numbers
We can use;
a + (n-1)d = T
a is 1, d is 2 and T is 99
Thus;
1 + 2(n-1) = 99
n-1 = (99-1)/2
n-1 = 59
n = 50
So there are 50 odd numbers
Probability of selecting an odd number is 50/100 = 1/2
If all 4 are odd, we have 1/2^4 = 1/16
Let’s get the multiples of 3
we can use
a + (n-1)d = T
a = 3, n = ? , d = 3 and T = 99
So;
3 + 3(n-1) = 99
n-1 = 34
n = 33
So the probability is 33/100
All 4 are divisible will give 33/100^4
Multiples of 5
a + (n-1)d = T
a = 5, n = ? , d = 5 T = 100
5 + (n-1)5 = 100
5(n-1) = 95
n-1 = 19
n = 20
Probability is 20/100 = 1/5
All
four are multiples of 5
1/5^4 = 1/625
So the probability is;
1/16 + 1/625 + 0.01185921
= 0.0625 + 0.0016 + 0.01185921 = 0.07595921
