A. The interest Bianca earned for a period of 3 years is $382.50. The correct option is B. $382.50
B. The number of years Bianca kept the account open is 11 years
Calculating simple interestFrom the question, we are to calculate how much interest Bianca will earn for a period of 3 years
From the simple interest formula, we have that
S.I = PRT
Where S.I is the simple interest
P is the principal
R is the rate
and T is the time
From the given information
P = $3,000
R = 4.25% = 0.0425
T = 3
Therefore,
S.I = $3,000 × 0.0425 × 3
S.I = $382.50
B.
From the given information, Bianca receives $4,402.50 when she closes the account
Thus,
The simple interest = $4,402.50 - $3,000
Simple interest = $1402.5
We are to calculate how many years Bianca kept the account open. That is, T
Using the formula,
S.I = PRT
$1402.5 = $3000 × 0.0425 × T
$1402.5 = $127.5 × T
T = $1402.5/$127.5
T = 11
Hence, the time is 11 years

The local ranger station tracked and tagged 2,844 adult female black bears in a national park. A random sample of 9 adult female black bears from those tagged had an average body weight of 203 pounds with standard deviation 25 pounds. Which of the following is a point estimate for the population mean weight of all female black bears that are tagged?
a. 9
b. 25/√9
c. 25
d. 203
e. 2,844
Answers
Answer:
203
Step-by-step explanation:
Sample size, n = 9
Mean weight, m = 203
Standard deviation = 25
Point estimate for the population mean weight of all black bears that are tagged `
The point estimate of the population mean ;
ΣX / n
Sum of sample / sample size ;
This is the mean value formula for the sample.
However, since it has been given in the question that, sample mean weight value = 203 ; then the point estimate of the population mean weight = 203
Option d: 203 is a point estimate for the population mean weight of all female black bears that are tagged.
Given that:Total tagged adult female black bears in the national park = 2,844Sample size = 9Sample mean of body weight of female black bears = 203 pounds.To find:Point estimate of population mean weight of female black bears that are tagged.
Calculations and explanations:Point estimation of population mean is calculated by calculating the mean of the sample drawn from that population. This estimate is considered best guess of population mean.
The sample mean is obtained by:
[tex]\overline{x} = \dfrac{\sum \text{sample observations}}{\text{sample size}}[/tex]
Since it is given that the sample mean is 203, thus we have the point estimate of the population mean as 203 too.
Thus, 203 is a point estimate for the population mean weight of all female black bears that are tagged.

x * x * x would equal x^3, since this is being multiplied.
x^3 is equal to x * x * x, therefore it is not correct.
x + 3 is not correct because you cannot add numbers or variables that are not like terms, so it would not equal to 3y.
x + x + x would equal to 3y because they are all like terms and do not form exponents.

Answer:
y = -16x + 16
Step-by-step explanation:
You can write a linear equation by getting the slope (m) and y-intercept (b).
To get the slope, you have to (y2 - y1) / (x2 - x1).
Which in this case, I'm going to used points (0,16) and (1,0).
So,
(0 - 16) / (1 - 0) = -16 / 1 = -16
m = -16
Now since we have the slope, the equation would look like y = -16x + b
You then have to input any x and y points (I'm going to use 1,0).
0 = -16(1) + b
0 = -16 + b
b = 16
Put this all together,
y = -16x + 16
Hope this helps :)

A ticket to Silver Dollar City costs $125. You have a coupon that will save you 33%. How much will you SAVE? In the same scenario, how much will you end up SPENDING for you ticket if you use your coupon?
Answers
To get the percent of money you save you multiply 125 dollars by 33% to get your answer. To get the number of dollars you will take the amount you got by multiplying 125 dollars by 33% and subtract it from 125, so that’s 125 - 41.25 = 83.75

a) Sketch the graph of g(x).
b) Find the inverse g-1(x) of g(x) then sketch the graph of g-1(x). c) Specify the domain and range of g(x) and g-1(x).
d) Determine the end behavior of g(x) and g-1(x).
Answers
Answer:
Step-by-step explanation:
a) The graph rises steeply from the third quadrant and there is a point of inflection through the origin (0, 0) then rises steeply in quadrant 1.
b) Let y = g(x) = x^3
x = ∛y
So g(-1)x = ∛x.
The graph is the reflection of g(x) in y = x.
c) Domain of g(x) = All real x, Range is all real g(x).
Domain of g(-1)x = All real x, Range = all real g-1(x).
d) You will see the end behaviour from the graphs.
