A jar has dimes and nickels. The number of dimes is four less than seven times the number of nickels. Let n represent the number of nickels. Write an expression for the number of dimes.
Answers
Answer:
d = 7n -4
Step-by-step explanation:
d is number of dimes, n is number of nickels.
7 X number of nickels = 7n.
4 less than that is 7n - 4.
so d = 7n -4.

A lumber company is interested in seeing if the number of board feet per has decreased since moving to a new location of timber. In the past, the company has an average 93 board feet per tree. The company believes that the production has decreased changing locations, a random sample of 25 trees yields mean of 89 with standard deviation of 2.Assuming normality of the data, test the hypothesis at a 10 % level of significance.
Answers
There is sufficient evidence to suggest that the mean board feet per tree has decreased since moving to the new location of timber.
According to the information,
Set up the following hypothesis test:
Null hypothesis: The mean board feet per tree is still 93.
Alternative hypothesis: The mean board feet per tree is less than 93.
Here,
We can use a one-sample t-test to test this hypothesis.
The test statistic can be calculated as:
t = (sample mean - hypothesized mean)/(sample standard deviation/square root of sample size)
⇒ t = (89 - 93)/(2/sqrt(25))
⇒ t = -5.00
The degrees of freedom for this test are 24.
Using a t-distribution table,
we can find the critical t-value for a one-tailed test with 24 degrees of freedom and a 10% level of significance.
The critical t-value is -1.317.
Since our calculated t-value (-5.00) is less than the critical t-value (-1.317), we can reject the null hypothesis in favor of the alternative hypothesis.

The measure of angle 1 in the given figure is 56 degrees.
What is the measure of angle 1?From the image of the angle:
Measure of angle ABD = 62 degrees
Measure of angle 2 = 6 degrees
Measure of angle 1 = ?
From the diagram, angle 1 and angle 2 makes up angle ABD.
To solve for the missing angle ( angle 1 ), sum up both angle 1 and 2 and equate to angle ABD.
Hence:
Angle 1 + Angle 2 = Angle ABD
Plug in the values and simplify:
m∠1 + 6 = 62
Subtract 6 from both sides
m∠1 + 6 - 6 = 62 - 6
m∠1 = 62 - 6
m∠1 = 56 degrees
Therefore, angle 1 measures 56 degrees.

The thickness of the ice floe is 3.9 centimeters.
Given that an ice floe's thickness is measured by an arctic ecologist. It measures 0.039 m thick.
We need to determine the thickness in centimeters,
Using the concept of unit conversion,
Since there are 100 centimeters in a meters, you must multiply the figure by 100 to convert from meters to centimeters.
The ice floe's thickness is 0.039 m, which may be converted to centimeters as follows:
100 cm/m times 0.039 m equals 3.9 cm.
The ice floe is 3.9 centimeters thick as a result.

To compute the Modified Internal Rate of Return (MIRR) for Project J, we need to calculate the present value of cash inflows and outflows separately and then determine the discount rate that equates the present value of outflows with the future value of inflows.
The cash flows for Project J are as follows:
Time 0: Initial investment: -$1,000
Time 1: Cash inflow: $300
Time 2: Cash inflow: $1,480
Time 3: Cash inflow: $500
Time 5: Cash inflow: $100
First, let's calculate the present value (PV) of outflows (the initial investment):
PV(outflows) = -$1,000 (since it's an outflow at time 0)
Next, let's calculate the future value (FV) of inflows (cash inflows at times 1, 2, 3, and 5):
FV(inflows) = $300 + $1,480 + $500 + $100 = $2,380
Now, we can use the MIRR formula to compute the MIRR statistic:
MIRR = (FV(inflows) / PV(outflows))^(1/n) - 1
Where n is the number of periods (5 in this case).
MIRR = ($2,380 / -$1,000)^(1/5) - 1
MIRR = 1.5189 - 1
MIRR = 0.5189 or 51.89%
Given that the cost of capital is 10 percent, the MIRR is higher than the cost of capital. Therefore, we would advise accepting Project J because the MIRR is greater than the cost of capital, indicating that the project is expected to generate a return higher than the required rate of return.

Subtract 2x from both sides:
4x - 2x + 6 < 2x - 2x + 12
2x + 6 < 12
Subtract 6 from both sides:

2x < 6
Divide both sides by 2

What is the intermediate step in the form(x+a)^2=b as a result of completing the square for the following equation?
X^2-8x+32=12x-4
Answers
Answer:
To complete the square for the equation X^2-8x+32=12x-4, we first need to move all the constant terms to one side of the equation and all the variable terms to the other side.
X^2 - 8x - 12x + 32 = -4
Next, we can simplify the equation by combining like terms:
X^2 - 20x + 32 = -4
Then, we can add a constant term to both sides of the equation such that the left side becomes a perfect square trinomial:
X^2 - 20x + 100 = 64
Finally, we can write the left side of the equation in the form (x - a)^2, where a is a constant:
(X - 10)^2 = 64
Therefore, the intermediate step in the form (x + a)^2 = b as a result of completing the square for the equation X^2 - 8x + 32 = 12x - 4 is (X - 10)^2 = 64.
