Answer: In 7 years, Ms Acosta will earn $37,734.7
Step-by-step explanation:
From the information given, we find the increase using exponential growth formula
A= P(1+r)^t
Where p= the starting amount on the contract, given as $34000
r = rate, given at 1.5% = 1.5/100 = 0.015
t = time, given as 7years
Plug the values into the formula:
A = 34000(1 + 0.015) ^7
= 34000 (1.015)^7
34000 x 1.1098
A= $37,734.7
In 7 years, Ms Acosta will earn $37,734.7.
Answer:
The answer to the given problem is provided below.
Step-by-step explanation:
She can make the conclusion at 95% confidence level that average sales have increased:
Since the sample mean, $2,984, falls outside the range of likely sample means (which has an upper bound=$2,843.44), the store owner can reject the null hypothesis that μ≤ $2,700 μ≤ $2,700 at a 95% confidence level.
Since she can reject the null hypothesis, she can essentially accept the alternative hypothesis and conclude the average daily sales have increased.
You don't see any y values that are the same, so you have to write the equations first
equation 1: the slope is m=(14-2)/(3-0)=4, and the y intercept is 2 (you can tell from the point (0,2)) so the equation is: y=4x+2
equation 2:
your last pair of x and y are not correct. they must be 3, -3 instead, not 3, 3
the slope is m=[(-3-(-12)]/(3-0)=3, and the y intercept is -12, so the equation is y=3x-12
solve the system of equation: y=4x+2 and y=3x-12
4x+2=3x-12
x=-14
y=3x-12=3*(-14)-12=-54
so the answer is (-14, -54)
