Answers
Answer:
C
Step-by-step explanation:
The following shows a proper representation of vector addition using the head -to-tail method is option c.
What is vector addition ?
Vector addition is a method for combining two or more vectors to obtain a resulting vector. Vector addition is performed by adding the corresponding components of each vector.
Given that,
Two vectors,
Vector 1: u
Vector 2: v
the sum of both the vectors = ?
According head to tail method of vector addition
Head of any one vector will be added to tail of the another vector,
And in this process,
if we draw another vector, by connecting its tail with tail of vector 1 & its head with head of vector 2
then it will be a resultant of addition of two vectors
Hence, in the figure in the option c is following all the rules of method

A researcher conducts a hypothesis test using a sample of n = 40 from an unknown population. What is the df value for the t statistic?
a. 38
b. 39
c. 40
d. 41
Answers
Answer:
Correct option: b 39.
Step-by-step explanation:
A one-sample (or one mean) t-test is applied to test whether the population-parameter is significantly different from some hypothetical value.
The degrees of freedom of the t-test is:
df = n - 1
It is provided that the sample size is, n = 40.
Compute the degrees of freedom as follows:
df = n - 1
= 40 - 1
= 39
Thus, the correct option is b.

B) 3(820) + 2(220)
C) 2460 + 660
D) 820 x 220 x 3
Answers
The expression that gives you a value of 3 times larger than (820 + 220) are:
3(820 + 220)
2460 + 660
Options A and C are the correct answer.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
(820 + 220)
= 1040
Now,
3 x 1040
= 3120
Now,
A)
3(820 + 220)
= 3 x 1040
= 3120
B)
3(820) + 2(220)
= 2460 + 440
= 2900
C)
2460 + 660
= 3120
D)
820 x 220 x 3
= 541200
Thus,
3(820 + 220) and 2460 + 660 give the value of 3 times larger than
(820 + 220).

An EWMA control chart uses λ = 0.5. What is the value of L such that the control limits of this EWMA control chart in the steady state have the same width with a 3σ X_bar control chart?
Answers
Answer:
5.199
Step-by-step explanation:
From the information provided;
We know that λ = 0.5.
However, the control limits for a steady-state EMWA control chart is:
[tex]\mu_o \pm L \sigma \sqrt{\dfrac{\lambda }{(2-\lambda )n}}[/tex]
where;
[tex]UCL = \mu_o + L \sigma \sqrt{\dfrac{\lambda }{(2-\lambda )n}}[/tex]
[tex]LCL = \mu_o- L \sigma \sqrt{\dfrac{\lambda }{(2-\lambda )n}}[/tex]
Given that the data is chosen from an individual sample;
Then; we can express the width as:
[tex]L \sigma \sqrt{\dfrac{\lambda}{(2-\lambda)}}= 3 \sigma[/tex]
[tex]L \sqrt{\dfrac{\lambda}{(2-\lambda)}}= 3[/tex]
[tex]L \sqrt{\dfrac{0.5}{(2-0.5)}}= 3[/tex]
[tex]L \sqrt{\dfrac{0.5}{(1.5)}}= 3[/tex]
[tex]L \sqrt{0.333}= 3[/tex]
[tex]L\times 0.577= 3[/tex]
[tex]L=\dfrac{ 3 }{0.577}[/tex]
L = 5.199

Sandals are on sale for 30% off. The original price of one pair of sandals is $30
What is the new cost of sandals after the discount?
Answers
Answer:
$21
Step-by-step explanation:
Original price of sandal = $30
Discount = 30%
What is the new cost of sandals after the discount?
Amount of discount = discount × original price
= 30% × $30
= 30 / 100 × 30
= 9
Amount of discount = $9
New price of sandal = Old price - amount of discount
= $30 - $9
= $21
New price of sandal = $21
