Answer:
Step-by-step explanation:
y=4 times 1/2 to the power of x can be written symbolically as
4 4
y = 4(1/2)^x. This is the same as y = ------- or y = -------- * 2^(-x)
2^x 1
This function is a "decaying exponential."
A suitable table follows:
x 4(2^[-x]) x y
0 4(2^0) (0, 4)
1 4(2^1) (1, 8)
2 4(2^2) (2, 16)
and so on.
Answer:
148-13=135
4x+13= - 3.25
6x+2 = - 0.33
Step-by-step explanation:
1) SIMPLE SUBTRACTION
148
- 13
---------
135
---------
2)
4x+13=0
4x= - 13
x= -13/4
x= - 3.25
3)
6x+2 = 0
6x= -2
x= -2/6
x = -0.33
the answer for the second problem is x=99 degrees and y= 261 degrees
dunno the first problem :/
Answer:
2.15%
Step-by-step explanation:
If you were to get the z-score for both 500 and 550 and then get the probability of both those z-scores. After getting the probability you would subtract both probability and get your answer.
Z-score:
550-400/2=3
500-400/2=2
Probability:
3 (from the Z-table) is .9987
2 (from the Z-table) is .9772
.9987-.9772= .0215
.0215 as a percentage is 2.15%
