Answer:
X = 11
Step-by-step explanation:
4x - 26 = 18
Add 26 on both sides to get 4x alone.
4x - 26 + 26 = 18 + 26
4x = 44
44 divided by 4 is 11.
Therefore X is 11.
Answer: x=11
Step-by-step explanation:
Add 26 to both sides
4x-26+26=18+26
4x=44
Divide by 4 and get 11
x=11

A couple purchased a home and signed a mortgage contract for $900,000 to
be paid with half-yearly payments over a 25-year period. The interest rate
applicable is j2 = 5.5% p.a. applicable for the first five years, with the condition
that the interest rate will be increased by 12% every 5 years for the remaining
term of the loan.
(a) Calculate the half-yearly payment required for each five-year interval

Answer:
$33,336.83$35,176.68$36,869.23$38,266.75$39,158.08Step-by-step explanation:
The amortization formula can be used to find the payment value.
A = P(r/2)/(1 -(1 +r/2)^(2n))
where P is the principal amount at the beginning of the loan period, r is the annual interest rate, n is the number of years remaining on the loan
The value of A in this scenario is the semi-annual payment.
Initially, the interest rate is 0.055 and the number of years remaining is 25.
After the first 5-year period, the interest rate goes up by 12%, so is multiplied by a factor of 1.12 to become 6.16% per year. The same growth factor is applied to the interest rate at the beginning of each 5-year period.
Of course, the number of years remaining is decreased by 5 years at the beginning of the next 5-year period.
__
The Principal remaining at the end of each 5-year period is the starting principal for the next period. It is calculated from ...
FV = P(1 +r/2)^10 -A((1 +r/2)^10 -1)/(r/2)
Where P is the starting principal, A is the loan payment as calculated above, and r is the annual interest rate.
__
These formulas are built into spreadsheet functions, so the desired set of loan payments can be calculated easily by that technology. The result is attached. In the "# pmts" column is the value used to amortize the loan for the 5-year period. The semiannual payment is calculated as though the loan would be completely paid off in that number of payments, keeping the same interest rate for the duration. Of course, that payment series is interrupted and the loan recalculated at the beginning of the next 5 years.
The half-yearly payments for each 5-year interval are ...

$35,176.68
$36,869.23
$38,266.75

The values displayed in the spreadsheet are rounded to the values shown. The values used in calculation have 14 or more significant digits. This means the numbers here may vary from those provided by a lending institution. In the real world, the principal and interest values are rounded to cents with each payment, so actual results may vary by a few cents either way.
A circular sinkhole has a radius of 12 meters. A week later, it has a diameter of 48 meters. How much greater is the circumference of the sinkhole compared to the previous week?
Answer:
B
Step-by-step explanation:
1) initial circumference
radius * 2 * pi = 24 * pi = 75,398224
2) final circumference
diameter * pi = 48 * pi = 150,796447
150,796447 - 75,398224 = 75.36 m

An agricultural researcher plants 25 plots with a new variety of corn. The average yield for these plots is 150 bushels per acre. Assume that the yield per acre for the new variety of corn follows a Normal distribution with unknown mean μ and that a 95% confidence interval for μ is found to be 150 ± 3.29. Which of the following options gives the correct notation for and value of the point estimate?
A) n=25
B) μ= 150
C) x=150
D) =150
E) P=150
Answer: C is the correct option.
Step-by-step explanation:
Confidence interval for population mean:
[tex]\overline{x}\pm E[/tex]
, where [tex]\overline{x}[/tex] = Sample mean
E = Margin of error
Given confidence interval : 150 ± 3.29
Here , [tex]\overline{x}=150, E=3.29[/tex]
Since the sample mean is the best estimate for the population mean.
Thus, the correct notation is [tex]\overline{x}=150[/tex]
i.e. C is the correct option.

You can use any of several other strategies, including finding the slope and y-intercept, then rearranging the equation.
Another strategy that works is to try the answer choices. You might notice that the first given point works in the first equation, so it may make sense to try the second given point in each equation.
The above version of the equation of a line is a variation on one that says the slope of a line is the same everywhere:
[tex]\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{y-y_1}{x-x_1}\ \Rightarrow\ (y_2-y_1)(x-x_1)=(x_2-x_1)(y-y_1)\\\\(y_2-y_1)(x-x_1)-(x_2-x_1)(y-y_1)=0[/tex]
The delivery truck drove 5 miles from store A to store B. Then the truck drove 13 miles from store B to the warehouse. If store A is directly south of store B and directly east of the warehouse, how far is store A from the warehouse!
Answer:
The distance from the store A to the warehouse is of 13.93 miles.
Step-by-step explanation:
The delivery truck drove 5 miles from store A to store B
5 miles south.
13 miles from store B to the warehouse.
13 miles east.
The situation can be represented by:
A
B Warehouse
In which the distance of A to B is of 5 miles, and the distance of B to the warehouse is of 13 miles. Thus, the distance of store A to the warehouse is the hypothenuse of a right triangle, with sides 5 and 13.
Using the Pytagorean Theorem:
[tex]h^2 = 5^2 + 13^2[/tex]
[tex]h^2 = 25 + 169[/tex]
[tex]h^2 = 194[/tex]
[tex]h = \sqrt{194}[/tex]
[tex]h = 13.93[/tex]
The distance from the store A to the warehouse is of 13.93 miles.
Based on historical data, your manager believes that 33% of the company's orders come from first-time customers. A random sample of 163 orders will be used to estimate the proportion of first-time-customers. What is the probability that the sample proportion is greater than 0.28
Answer:
[tex]P(x > 0.28) = 1[/tex]
Step-by-step explanation:
Given
[tex]p = 33\%[/tex] --- orders from first time customer
[tex]n =163[/tex] --- samples
Required
[tex]P(x >0.28)[/tex]
First, calculate the mean
[tex]\bar x = np[/tex]
[tex]\bar x = 163 * 33\%[/tex]
[tex]\bar x = 53.79[/tex]
Next, the standard deviation
[tex]\sigma = \sqrt{\bar x * (1 - p)[/tex]
[tex]\sigma = \sqrt{53.79* (1 - 33\%)[/tex]
[tex]\sigma = \sqrt{53.79* (1 - 0.33)[/tex]
[tex]\sigma = \sqrt{53.79* 0.67[/tex]
[tex]\sigma = 6.00[/tex]
For [tex]P(x >0.28)[/tex],
The z score is:
[tex]z = \frac{x - \bar x}{\sigma}[/tex]
[tex]z = \frac{0.28 - 53.79}{6}[/tex]
[tex]z = \frac{-53.51}{6}[/tex]
[tex]z = -8.92[/tex]
So:
[tex]P(x > 0.28) = P(z > -8.92)[/tex]
From z probability:
[tex]P(z > -8.92) =1[/tex]
Hence:
[tex]P(x > 0.28) = 1[/tex]

What is the measure of angle y in the figure?
Answer:
y = 27
Step-by-step explanation:
The sum of the two angles is a right angle, which is 90 degrees
y+63 = 90
y = 90-63
y =27
Answer:
The measures of angle y is 30 °.
Step-by-step explanation:
We know that, the sum of two side of right angle is 90 °.
60 ° + y = 90 °
subtract 60 ° from each side
y = 90 ° - 60
y = 30 °
Therefore, the measures of angle y is 30°.

Answer:
Answer is A
Step-by-step explanation:
A density graph is used to find the probability of a discrete random variable
taking on a range of values.
A. True
B. False
Answer:
False
Step-by-step explanation:
This is false because A density graph is not used to find the probability of a discrete random variable taking on a range of values. This is because you have to use a calculations instead of a graph. The correct how to calculate is: Determine a single event with a single outcome. Identify the total number of outcomes that can occur. Divide the number of events by the number of possible outcomes.
Therefore, it's B ( false).
