Step-by-step explanation:
The measures of the angles In alinear pair are x degree and (x+25) degree. Find the measures of each of them
Answer:
77.5° and
102.5°
Step-by-step explanation:
Angles in a linear pair sum up to 180°
Therefore, x + (x +25) = 180
x + x +25 = 180
2x + 25 = 180
2x = 180- 25
2x 155°
dividing bothsides by 2
x = 155/2
x = 77.5
Therefore,
x = 77.5°
(x+25) = 77.5 + 25 = 102.5°

31.03%
93.09%
9.73%
The rate of return earned on the investment of $475 five years ago in the corporate stock is 312.63%.
What is the rate of return?The rate of return is the net gain or loss of an investment expressed as a percentage of the investment's initial cost.
It is given by the formula, R= {Vf - Vi}/{Vi} x 100.
Where:
R = Rate of return
Vf = final value, including dividends and interest
Vi = initial value
Data and Calculations:Investment cost = $475
Dividends received:
1st two years = $80 ($10 x 8)
Three years = $180 ($15 x 12)
Total dividends received = $260 ($80 + $180)
Total revenue from sale = $1,700
Total proceeds = $1,960 ($1,700 + $260)
Total return = $1,485 ($1,960 - $475)
Rate of return = 312.63% ($1,485/$475 x 100)

The problem proves that the distributor's claim is true and he has a right to complain.
But when the confidence interval is changed from 95% to 90% the distributor's claim proves to be false.
The Confidence Interval for 95% is 0.9687;0.98532
For a sample size of n>30 the central limit theorem allows us to assume that the sampling distribution of x~ is approximately normal.
The critical region is Z ≥ 1.28 therefore the 1.877 lies in the rejection region that the distributor's claim is not true.
The Confidence Interval for 90% is 0.97156;0.982431
Here
μ = 0.977
s= σ= 0.03
95 % confidence interval is given by
x~± z∝/2 (s/√n)
Putting the values
0.977 ± 1.96 (0.03/√50)
=0.977 ± 0.008315
0.9687;0.98532
Part B:
x~+ 0.95= 0.977+0.95= 1.927
The critical region is Z ≥ 1.96 therefore the 1.927 lies in the acceptance region that the distributor's claim is true.
Part C:
For a sample size of n>30 the central limit theorem allows us to assume that the sampling distribution of x~ is approximately normal.
Part D:
μ = 0.977
s= σ= 0.03
90 % confidence interval is given by
x~± z∝/2 (s/√n)
Putting the values
0.977 ± 1.28 (0.03/√50)
=0.977 ± 0.005431
0.97156;0.982431
Part D:
x~+ 0.90= 0.977+0.90= 1.877
The critical region is Z ≥ 1.28 therefore the 1.877 lies in the rejection region that the distributor's claim is not true.

a group of 4 numbers have an average of 15, three of the numbers are 18,11 and 25. what is the other number??
Answer:
6
Step-by-step explanation:
The average of a set of numbers is their sum divided by their number. This fact lets us write an equation to find the missing number.
SetupLet x represent the missing number. The average of the 4 numbers is ...
(x +18 +11 +25)/4 = 15
SolutionMultiplying by 4 gives ...
x +54 = 60
Subtracting 54, we find the missing number:
x = 6
The other number is 6.
What is the extraneous solution found in solving the equation log2 4x + log₂ (x + 1) = 3
Answer:
x = -2
Step-by-step explanation:
We are given the logarithmic base 2 equation of:
[tex]\displaystyle{\log_2 (4x) + \log_2 (x+1) = 3}[/tex]
Apply logarithm property of addition where:
[tex]\displaystyle{\log_a M + \log_a N = \log_a MN}[/tex]
Therefore, we will write new equation as:
[tex]\displaystyle{\log_2 [4x(x+1)] = 3}[/tex]
Apply logarithm to exponential form using:
[tex]\displaystyle{\log_a M = N \to a^N = M}[/tex]
Thus, another new rewritten equation is:
[tex]\displaystyle{2^3 = 4x(x+1)}\\\\\displaystyle{8 = 4x(x+1)}\\\\\displaystyle{2=x(x+1)}[/tex]
Expand the expression in and arrange the terms in quadratic expression:
[tex]\displaystyle{2=x^2+x}\\\\\displaystyle{0=x^2+x-2}\\\\\displaystyle{x^2+x-2=0}[/tex]
Solve for x:
[tex]\displaystyle{(x+2)(x-1)=0}\\\\\displaystyle{x=-2,1}[/tex]
These are potential solutions to the equation. To find extraneous solution, you’ll have to know the domain of logarithm function. We know that logarithm’s domain is defined to be greater than 0. Henceforth, anti-logarithm must be greater than 0.
( 1 ) 4x > 0, x > 0
( 2 ) x + 1 > 0, x > -1
Therefore, our anti-log must be greater than 0, so any solutions that are equal or less than 0 will be considered as extraneous solution.
Hence, x = -2 is the extraneous solution.

Using the normal distribution, it is found that the probabilities are given as follows:
a) 0.8871 = 88.71%.
b) 0.0778 = 7.78%.
c) 0.8485 = 84.85%.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].The parameters in this problem are given as follows:
[tex]\mu = 1140, \sigma = 310, n = 16, s = \frac{310}{\sqrt{16}} = 77.5[/tex]
Item a:
The probability is the p-value of Z when X = 1250 subtracted by the p-value of Z when X = 1000, hence:
X = 1250:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{1250 - 1140}{77.5}[/tex]
Z = 1.42
Z = 1.42 has a p-value of 0.9222.
X = 1000:
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{1000 - 1140}{77.5}[/tex]
Z = -1.81
Z = -1.81 has a p-value of 0.0351.
0.9222 - 0.0351 = 0.8871 = 88.71% probability.
Item b:
The probability is one subtracted by the p-value of Z when X = 1250, hence:
1 - 0.9222 = 0.0778 = 7.78%.
Item c:
The probability is the p-value of Z when X = 1220, hence:
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{1220 - 1140}{77.5}[/tex]
Z = 1.03
Z = 1.03 has a p-value of 0.8485.
0.8485 = 84.85% probability.
