Answer:
D) 0.0796
Step-by-step explanation:
Birth weights in Norway are normally distributed with a mean of 3570 g and a standard deviation of 500 g.
mean = 3570 and SD = 500
We need to find P(3500<x<3600)
P(3500<x<3600)= P(x=3600)- P(x=3500)
to find P(x=3600) we find z-score
Now use z-score table . z-score = 0.5239
P(x=3600)=0.6179
to find P(x=3500) we find z-score
Now use z-score table . z-score = 0.4443
P(x=3600)=0.4443
P(3500<x<3600)= P(x=3600)- P(x=3500)
P(3500<x<3600)=0.5239-0.4443 = 0.0796

Answer:
y = 0.2·0.5^x
Step-by-step explanation:
The form of an exponential function is ...
y = a·b^x
If you look at the values of this for x=0 and x=1, you find ...
<u>For x=0</u>
y = a·b^0 = a·1 = a
The table tells us the corresponding value of y is 0.2, so ...
a = 0.2
<u>For x=1</u>
y = a·b^1 = ab
For the given value of a and the table value of y for x=1, we have ...
0.1 = 0.2·b
b = 0.1/0.2 = 1/2 = 0.5
Then the exponential function that describes the table is ...
y = 0.2·0.5^x
This answer would be -375
Answer:
y = 3x + 2
Step-by-step explanation:
If the line is parallel, then the slope remains the same.
To find the y-intercept, just plug the coordinates into the equation
y = 3x + b
14 = 3(4) + b
14 = 12 + b
2 = b
The equation is y = 3x + 2
