Answer:
Step-by-step explanation:
we know that
The equation of a exponential function is of the form
where
a is the initial value or y-intercept
b is the base of the exponential function
In this problem we have
----> the y-intercept is given
substitute
we have the other ordered pair (1,10)
substitute the value of x and the value of y and solve for b
substitute
see the attached figure to better understand the problem
Answer:
c
Step-by-step explanation:
subtract b from both sides
divide by x
Answer:
The margin of error for a sample size of 250 is 6
Step-by-step explanation:
The margin of error is given as
1/square root of the sample size
Thus, margin of error for a sapless size of 250 is
1/√250
= 1/15. 811
= 6
Answer:
y=2x-3
Step-by-step explanation:
show work
1=(2*2)+b
1=4+b
1-4=-3
-3=b
check work
y=2x-3
y=(2*2)-3
y=4-3
y=1
Answer: - 32
Step-by-step explanation:
-8 + (-24)
Infront of the Positive is a one.
-8 +1 (-24)
If we follow order of operations which is parentheses, exponents, multiply divide, add, and subtract, we can see we need to multiply/ distribute first. And a positive times a negative is a negative.
-8 -24
Now we put the two numbers together.
-32
This is the answer
