Answer:
Therefore, the solution is:
Step-by-step explanation:
We calculate the given integral. We use the substitution t = 7x.
Therefore, the solution is:
Answer:
Step-by-step explanation:
If x represents the amount invested at 7%, then the amount invested at 13% is x+300. Lydia's total interest is ...
0.07x +0.13(x +300) = 252
0.20x = 213 . . . . . subtract 39
x = 213/0.20 = 1065
Lydia has $1065 invested at 7% and $1365 invested at 13%.
Using the given conditions, we set up and solve an equation where x is the amount invested at a 7% rate and x + $300 is the amount at a 13% rate. After solving, we find that Lydia has $1065 in the 7% account and $1365 in the 13% account.
Let's assume Lydia's investment at 7% to be x and her investment at 13% to be x + $300. Since the total interest is $252, we can create an equation to solve for the values of x.
The equation will look like this:
0.07x + 0.13(x + 300) = 252
Let's solve the equation:
0.07x + 0.13x + 39 = 252
Combine like terms to get 0.2x + 39 = 252
Subtract 39 from both sides to get 0.2x = 213
Divide by 0.2 to solve for x, which gives x = 1065.
So, Lydia has $1065 in the 7% account and $1065 + $300 = $1365 in the 13% account.

b. Using a critical value, test the null hypothesis at the 5% level of significance.
c. Using a p-value, test the hypothesis at the 5% level of significance.
d. What type of error may have been committed for this hypothesis test
Answer:
a)
b) The z-value (1.5) is smaller than z=1.645 (critical value), so it is in the "acceptance region". It failed to reject the null hypothesis.
c) The p-value (0.07) is greater than the significance level (0.05), so it failed to reject the null hypothesis.
d) In this case, the error we may hae comitted is a Type II error (failed to reject a null hypothesis that is false).
Step-by-step explanation:
We have to perfomr a hypothesis test on the mean, with known standard deviation of the population.
a) The null hypothesis is that the deliver time is 15 days or less.
The null and alternative hypothesis are then:
The significance level is defined as 0.05.
b) The critical value of z for a one-side test (rigth side) and a significance level of 0.05 is z=1.645.
If the z-value for this sample is higher than 1.645, it is in the "rejection region".
Calculating the z-value:
The z-value (1.5) is smaller than z=1.645 (critical value), so it is in the "acceptance region". It failed to reject the null hypothesis.
c) The p-value for z=1.5 is:
The p-value (0.07) is greater than the significance level (0.05), so it failed to reject the null hypothesis.
d) There are two types of error:
Type I errors: happen when we reject a null hypothesis that is true.
Type II errors: happen when we failed to reject a null hypothesis that is false.
In this case, the error we may hae comitted is a Type II error.
The null hypothesis at 5% significance level is 1.50
Data;
The alternative hypothesis are
H_o = mean = 15
standard deviation = 5.6 days
using z-test,
n is greater than or equal to 30
Assuming standard deviation is known
z-critical value is 1.96 at 95% confidence level.
Since z-critical value is greater than the test statistic, so we tail to subject H_o.
There's no evidence that mean delivery time is different from 15 days.

Domain of (f-g)(x) = (-∞, ∞)
3.
Substitute the values of the given functions.
The function is a polynomial which is defined for all real values x.
Domain of (fg)(x) = (-∞, ∞)
4.
Substitute the values of the given functions.
The function is a rational function which is defined for all real values x except 0.
Domain of (f/g)(x) = (-∞,0)∪(0, ∞)
, domain: all real numbers.
, domain: all real numbers.
, domain: all real numbers.
, domain: all real numbers.
To find (f + g)(x), we need to add the functions f(x) and g(x).
The function f(x) = x - 3 and the function
So,
Expanding this equation, we get
To find the domain of (f + g)(x), we need to consider the domain of the individual functions f(x) and g(x).
Since both f(x) = x - 3 and are defined for all real numbers, the domain of (f + g)(x) is also all real numbers.
To find (f - g)(x), we need to subtract the function g(x) from f(x).
So,
Expanding this equation, we get
The domain of (f - g)(x) is also all real numbers, since both f(x) and g(x) are defined for all real numbers.
To find (fg)(x), we need to multiply the functions f(x) and g(x).
So,
Expanding this equation, we get
The domain of (fg)(x) is all real numbers, since both f(x) and g(x) are defined for all real numbers.
To find f(g(x)), we need to substitute g(x) into the function f(x).
So,
The domain of f(g(x)) is also all real numbers, as is defined for all real numbers, and f(x) = x - 3 is defined for all real numbers.
In summary:
- , domain: all real numbers.
- , domain: all real numbers.
- , domain: all real numbers.
- , domain: all real numbers.
