Answer:
7/12
Step-by-step explanation:
Total = 10W+14R
probability of red = R/total
10+14 = 24 so total = 24
R = 14
14/24
reduce (divide by two on the top and bottom)
14/2
-------
24/2
= 7/12
Answer: No, New York students are not truly more nerdy than the California students.
Step-by-step explanation:
Since we have given that
Number of students in a group = 50
Mean score of New York psychology = 530
Mean score of California psychology = 515
Standard deviation = 80
So, we will find t-distribution first.
Let α = 5% = 0.05
So, 
Since t < t(critical value)
No, New York students are not truly more nerdy than the California students.
3/ x -1 - 4 / x + 2=2
I work a bit backwards so, lets try looking at it like this,
3/ X
-4/X
what could X be to let these be positive since our outcome is positive?
3/0=0
4/0=0
so 3/0-1= -1
-1-4/0= 0
+2= 2
so 2=2
so now we go and fill it in to make sure
3/0-1-4/0+2=2
and it works so,
X= 0
I hope this helped some
√18x / √50
= √9*√2x / √25*√2
= 3√x / 5
C
(x,y)
P = 50x + 80y
P=(0,5)
=50(0) + 80(5)
= 0 + 400
= 400
P=(1,12)
= 50(1) + 80(12)
= 50 + 960
= 1010
P=(4,10)
= 50(4) + 80(10)
= 2000 + 800
= 2800
