Answer: For number 1, the lines intersect, and for number 2, the lines are perpendicular.
Step-by-step explanation:
Perpendicular lines are lines that intersect to form a right angle, as shown for number 2, and intersecting lines are lines that intersect, creating obtuse and/or acute angles.
Liam bought pizza and wings for $27.58. How much change should Liam receive if he gave the clerk three $10 bills?
Use coins and bills to help solve.
A. $1.52
B. $2.42
C. $2.52
D. $12.42
Answer:
B. $2.42
Step-by-step explanation:
If Liam gave the clerk three $10 bills, that means he gave the clerk $30. This is because 3 times 10 equals 30.
Find how much change he will receive by subtracting $27.58 from the $30 that Liam gave to the clerk:
30 - 27.58
= 2.42
So, Liam will receive $2.42 in change.
The correct answer is B. $2.42
Answer:
2.42
Step-by-step explanation:
3 ten dollar bills = 3*10 = 30 dollars
Subtract the cost of pizza and wings
30 - 27.58
Line up the decimals
30.00
- 27.58
----------------
2.42
A craftsperson must attach a lead strip around all four sides of a stained glass window that is
8 4/5 in. by
14 17/25 in. before it is installed. Find the length of lead stripping needed.
9514 1404 393
Answer:
46 24/25 in
Step-by-step explanation:
Opposite pairs of sides are the same length, so the total length needed is ...
2(8 4/5 +14 17/25) = 2(8 20/25 +14 17/25) = 2(22 37/25) = 2(23 12/25)
= 46 24/25 . . . inches

A, B, and C are the coefficients. They are not the terms as you have written now.
A quadratic equation is in the form Ax^2 + Bx + C. Therefore, A = 1, B = 8, and C = -6.
The axis of symmetry is found using the equation -b/2a, as you've done. Therefore, the axis of symmetry is -8/2(1) = -4.

The variance in a production process is an important measure of the quality of the process. A large variance often signals an opportunity for improvement in the process by finding ways to reduce the process variance. Conduct a statistical test to determine whether there is a significant difference between the variances in the bag weights for the two machines. Use a level of significance. What is your conclusion? Which machine, if either, provides the greater opportunity for quality improvements? Click on the datafile logo to reference the data. (to 4 decimals) (to 4 decimals) (to 2 decimals) - Select your answer -
Answer:
There is a sufficient evidence to support the that machine 1 has the greater variance.
Step-by-step explanation:
The question with the complete details can be found online.
Start by stating the hypotheses.
The null hypothesis states that the variance of machine 1 is less than or equal to machine 2
So, we have:
[tex]H_o: \sigma_1 ^2 \le \sigma_2 ^2[/tex]
The alternate hypothesis will then be:
[tex]H_a: \sigma_1 ^2 > \sigma_2 ^2[/tex]
So, we have:
[tex]n_1 = 25[/tex] [tex]n_1 = 22[/tex]
Calculate the mean of Machine 1 and 2
The mean is:
[tex]\bar x =\frac{\sum x}{n}[/tex]
For machine 1, we have:
[tex]\bar x_1 =\frac{2.95+3.45+3.5+.....+3.12}{25}[/tex]
[tex]\bar x_1 =\frac{83.21}{25}[/tex]
[tex]\bar x_1 =3.3284[/tex]
For machine 2, we have:
[tex]\bar x_2 = \frac{3.22 + 3.3 + 3.34 + ..... +3.33}{22}[/tex]
[tex]\bar x_2 = \frac{72.12}{22}[/tex]
[tex]\bar x_2 = 3.2782[/tex]
Calculate the standard deviation of both machines
The standard deviation is:
[tex]\sigma = \sqrt{\frac{\sum(x - \bar x)^2}{n-1}}[/tex]
For machine 1, we have:
[tex]\sigma_1 = \sqrt{\frac{(2.95 - 3.3284)^2+(3.45 - 3.3284)^2+(3.5 - 3.3284)^2+.....+(3.12 - 3.3284)^2}{25-1}}[/tex]
[tex]\sigma_1 = \sqrt{\frac{(2.95 - 3.3284)^2+(3.45 - 3.3284)^2+(3.5 - 3.3284)^2+.....+(3.12 - 3.3284)^2}{24}}[/tex]
[tex]\sigma_1 = 0.2211[/tex]
For machine 2, we have:
[tex]\sigma_2 = \sqrt{\frac{(3.22 - 3.2782)^2+(3.3 - 3.2782)^2+(3.44 - 3.2782)^2+.....+(3.33 - 3.2782)^2}{22-1}}[/tex]
[tex]\sigma_2 = \sqrt{\frac{(3.22 - 3.2782)^2+(3.3 - 3.2782)^2+(3.44 - 3.2782)^2+.....+(3.33 - 3.2782)^2}{21}}[/tex]
[tex]\sigma_2 = 0.0768[/tex]
Calculate the degrees of freedom
[tex]df=n-1[/tex]
For machine 1;
[tex]df_1=25-1=24[/tex]
For machine 2
[tex]df_2=22-1=21[/tex]
Calculate the test statistic (t)
[tex]t = \frac{Var_1}{Var_2}[/tex]
Rewrite in terms of standard deviation
[tex]t = \frac{\sigma_1^2}{\sigma_2^2}[/tex]
[tex]t = \frac{0.2211^2}{0.0768^2}[/tex]
[tex]t = \frac{0.04888521}{0.00589824}[/tex]
[tex]t = 8.2881[/tex]
Lastly, calculate the p value.
This is the value of P(t > 8.2881) between the degrees of freedom i.e. 21 and 24
From the f distribution table
[tex]P(t > 8.2881) < 0.01[/tex]
Hence, we reject the null hypothesis

A) 10 ways
B) 31 ways
C) 26 ways
D) 41 ways
'Option B' is the correct answer....
The number of ways that students chose not a seventh grader will be 31 thus option (B) is correct
What are permutation and combination?When the order of the arrangements counts, a permutation is a numerical approach that establishes the total number of alternative arrangements in a collection.
The number of alternative configurations in a collection of things when the order of the selection is irrelevant is determined by combination.
As per the given,
There are 15 sixth graders, 10 seventh graders, and 16 eighth graders in a gym class.
Total number of students = 15 + 10 + 16 = 41
Students that not in 7th grade = 41 - 10 = 31
The number of ways to choose 1 from 31
31C1 = 31
Hence "There were 31 different methods in which students decided not to be a seventh grader".

2.02b + 4.30 = 2.00b + 6.30
Answer: b = 100
Step-by-step explanation:
simplifying
2.02b + 4.30 = 2.00b + 6.30
reorder the terms:
4.30 + 2.02b = 2.00b + 6.30
reorder the terms:
4.30 + 2.02b = 6.30 + 2.00b
solving
4.30 + 2.02b = 6.30 + 2.00b
solving for variable 'b'.
move all terms containing b to the left, all other terms to the right.
add '-2.00b' to each side of the equation.
4.30 + 2.02b + -2.00b = 6.30 + 2.00b + -2.00b
combine like terms: 2.02b + -2.00b = 0.02b
4.30 + 0.02b = 6.30 + 2.00b + -2.00b
combine like terms: 2.00b + -2.00b = 0.00
4.30 + 0.02b = 6.30 + 0.00
4.30 + 0.02b = 6.30
add '-4.30' to each side of the equation.
4.30 + -4.30 + 0.02b = 6.30 + -4.30
combine like terms: 4.30 + -4.30 = 0.00
0.00 + 0.02b = 6.30 + -4.30
0.02b = 6.30 + -4.30
combine like terms: 6.30 + -4.30 = 2
0.02b = 2
divide each side by '0.02'.
getting: b = 100

Randy's gross salary is $760 per week. his salary is taxed at 16% what is his net salary
Answer:
$638.4
Step-by-step explanation:
Randy's gross salary (salary without any deduction) = $760
taxed rate =16%
Amount tax paid =tax% of gross income
=16/100 * $760
=$16*760/100
=$12160/100
=$121.6
net salary = gross salary - tax paid
=$760 - $ 121.6
=$638.4
Randy's net salary is $638.40
Randy's gross salary = $760 per week.
Tax paid on his salary = 16%
Net salary is the difference between the salary earned and the amount paid as tax. This will be:
= Salary - Tax
= $760 - (16% × $760)
= $760 - (0.16 × $760)
= $760 - $121.60
= $638.40

Answer:
x = 6.93
y = 13.86
Step-by-step explanation:
We can solve x by;
Tan(60) = 12/x
Tan(60) * x = 12
x = 12 / Tan(60)
x = 6.93
We can solve y by;
A² + B² = C²
12² + 6.93² = y²
144 + 48.02 = y²
192.02 = y²
[tex]\sqrt{192.02}[/tex] = y²
