Answer:
27 degrees.
Step-by-step explanation:
If the average is to be 23 degrees over 5 days then the total of the temperatures will be 5*23 = 115 degrees.
The total over the first 4 days = 22*4 = 88 degrees, so the temperature on the fifth day has to be 115 - 88 = 27 degrees.
Answer: 10773
Step-by-step explanation:
.75^10=0.0563
look at 8, 9, 10
8 the probability is 10C8*0.75^8*0.25^2=0.2816
9 the probability is 0.1877 using the same approach
At least 8 is 0.5256
At most 4 is
0 .25^10=essentially 0
1: 10C1*0.75*0.25^9=<0.0001
2: 45*0.75^2*0.25^8=0.0004
3: 120*0.75^3*0.25^7=0.0031
4: 10C4*0.75^4*0.25^6=0.0162
That sum is 0.0197
Answer: 13
Step-by-step explanation:
8-10= 2 - 9 = 11 - 2 = 13 soo that how you got the answer 13 .
Answer:
A. (2, -1)
Step-by-step explanation:
(4x - 9) - x = -3
3x - 9 = - 3
3x = 6
x = 2
y = 4(2) - 9
y = 8 -9
y = - 1
(2, -1)
Check
-1 - 2 = -3
