Answer:
D. ∆XVW ≅ ∆XBC
Step-by-step explanation:
Angle X = Angle X (vertical angles are congruent)
Angle V = angle B (corresponding angles are congruent)
Angle W = angle C (corresponding angles are congruent)
The three angels in ∆XVW are congruent to the three corresponding angles in ∆XBC.
Therefore, the statement that indicates both triangles are congruent is:
∆XVW ≅ ∆XBC

Answer: 9
Step-by-step explanation:
To collect data on the signal strengths in a neighborhood, Briana must drive from house to house and take readings. She has a graduate student, Henry, to assist her. Briana figures it would take her 12 hours to complete the task working alone, and that it would take Henry 18 hours if he completed the task by himself. How long will it take Briana and Henry to complete the task together?
Answer:
Both take time together = 36 / 5 hours = 7.2 hours
Step-by-step explanation:
Given:
Briana take time = 12 hour
Henry take time = 18 hour
Find:
Both take time together
Computation:
Briana 1 hour work = 1/12
Henry 1 hour work = 1/18
Both take time together = 1/[1/12+1/18]
Both take time together = 1/[5/36]
Both take time together = 36 / 5 hours = 7.2 hours
The degree measure of one of two complementary angles is twice that of the other. What is one of the degree measures of the angles?
A.) 30 degrees
B.)40 degrees
C.)45 degrees
D.)27 degree
Answer:
30° is one of the degree measures of the angles.
Hence, option (A) is true.
Step-by-step explanation:
Let 'x' be the degree measure of the first angle.Given that the degree measure of one of two complementary angles is twice that of the other.
Thus, the other angle = 2xComplementary angles
We know that two angles are termed as complementary angles when the sum of their measured angles is 90°.Thus the equation becomes
x + 2x = 90°
3x = 90°
Divide both equations by 3
3x/3 = 90°/3
x = 30°
Therefore, 30° is one of the degree measures of the angles.
Hence, option (A) is true.
The degree measure of one of two complementary angles is twice that of the other. What is one of the degree measures of the angles?
Answer :A.) 30 degrees
Solution :Let one angle = x
According to statement,
Another angle = 2 × first angle
[tex] \sf : \implies Another \: angle = 2x[/tex]
Now, we know that sum of complementary angles is 90°
Hence,
[tex] \sf : \implies x + 2x = 90^{\circ}[/tex]
[tex] \sf : \implies 3x = 90^{\circ}[/tex]
[tex] \sf : \implies x = \dfrac{\cancel{90}^{\circ}}{\cancel{3}}[/tex]
[tex] \sf : \implies x = 30^{\circ}[/tex]
[tex] \Large \underline{\boxed{\sf{ x = 30^{\circ} }}}[/tex]
Therefore, one of the angle is 30°.
Another angle = 2 × 30° = 60°
I need help ASAP it’s compound interest and I’m not very good at it
Answer:
Part B:
5) She will have $4445.244256 in 3 years
Part C:
1) She will have $8081.130039 in 10 years
2) He will have $13360.55059 in 8 years
Step-by-step explanation:
The formula of the compound interest is A = P [tex](1+\frac{r}{n})^{nt}[/tex], where
A is the new valueP is the initial amountr is the rate in decimaln is the number of the periodt is the time in yearsPart B:
5)
∵ P = $4250
∵ r = 1.5% = 1.5 ÷ 100 = 0.015
∵ n = 4 ⇒ Compounded quartly
∵ t = 3 years
→ Substitute them in the formula above
∴ A = 4250 [tex](1+\frac{0.015}{4})^{4(3)}[/tex]
∴ A = 4250 [tex](1.00375)^{12}[/tex]
∴ A = 4445.244256
∴ She will have $4445.244256 in 3 years
Part C:
1)
∵ Grace deposits $6000
∴ P = 6000
∵ The account is compounded semi-annually at 3%
∴ r = 3% = 3 ÷ 100 = 0.03
∴ n = 2 ⇒ compounded semi-annually
∵ The time is 10 years
∴ t = 10
→ Substitute them in the formula above
∴ A = 6000 [tex](1+\frac{0.03}{2})^{2(10)}[/tex]
∴ A = 6000 [tex](1.015)^{20}[/tex]
∴ A = 8081.130039
∴ She will have $8081.130039 in 10 years
2)
∵ Danial opens an account that is compounded semi-annually at 5%
∴ r = 5% = 5 ÷ 100 = 0.05
∴ n = 2 ⇒ compounded semi-annually
∵ He deposits $9000
∴ P = 9000
∵ The time is 8 years
∴ t = 8
→ Substitute them in the formula above
∴ A = 9000 [tex](1+\frac{0.05}{2})^{2(8)}[/tex]
∴ A = 9000 [tex](1.025)^{16}[/tex]
∴ A = 13360.55059
∴ He will have $13360.55059 in 8 years

a company pays its employees and average hourly wage of 36.25 with a standard deviation of 6.50 more than 23.22 of 36 employees are randomly selected, what is the probability that their mean wage is more than 23.22
Answer:
P [ X > 23,22 ] = 0,8798 or P [ X > 23,22 ] = 87,98 %
Step-by-step explanation:
P [ X > 23,22 ] = 1 - P [X ≤ 23,22 ]
P [X ≤ 23,22 ] = ( X - μ₀ ) / σ /√n
P [X ≤ 23,22 ] = ( 23,22 - 36,25 )/ 6,50/√36
P [X ≤ 23,22 ] = - 13,03 *6 / 6,50
P [X ≤ 23,22 ] = - 12,02 or P [X ≤ 23,22 ] = 12,02 %
(note the - sign only mean that values on the left tail of the bell shape curve)
Then
P [ X > 23,22 ] = 1 - 0,1202
P [ X > 23,22 ] = 0,8798 or P [ X > 23,22 ] = 87,98 %

In a sample of 41 temperature readings taken from the freezer of a restaurant, the mean is 29.7 degrees and the population standard deviation is 2.7 degrees. What would be the 80% confidence interval for the temperatures in the freezer?
Answer: [tex]=(29.1596\text{ degrees},\ 30.2404\text{ degrees})[/tex]
Step-by-step explanation:
Given: Sample size: n = 41
Sample mean [tex]\overline{x}= 29.7[/tex] degrees
Population standard deviation [tex]\sigma=2.7[/tex] degrees
Confidence level (c) = 80% =0.80
Significance level (a) = 1- c = 1-0.80 = 0.20
z-score for 80% confidence level : z = 1.2816 [from z-table]
Confidence level for population mean :-
[tex]\overline{x}\pm z\dfrac{\sigma}{\sqrt{n}}[/tex]
[tex]=29.7\pm ( 1.2816)\dfrac{2.7}{\sqrt{41}}[/tex]
[tex]=29.7\pm ( 1.2816)\dfrac{2.7}{6.403124}[/tex]
[tex]=29.7\pm ( 1.2816)(0.42167)[/tex]
[tex]=29.7\pm 0.5404[/tex]
[tex]=(29.7-0.5404,\ 29.7+0.5404)[/tex]
[tex]=(29.1596,\ 30.2404)[/tex]
Hence, 80% confidence interval for the temperatures in the freezer [tex]=(29.1596\text{ degrees},\ 30.2404\text{ degrees})[/tex]
which is the correct answer?
Step-by-step explanation:
Step 3 is incorrect, it should be x - 4 + x = x(x - 3).
x - 4 + x = x(x - 3)
2x - 4 = x² - 3x
x² - 5x + 4 = 0
(x - 4)(x - 1) = 0
x = 4 or x = 1.
x = 4 is rejected as 1 / (x - 4) will become 1 / 0 which is undefined.
=> x = 1.
