Answer:
The angle between u and v is π/3 and parallel-to u plus v parallel-to = k*(u+v) (where k=const)
Step-by-step explanation:
In this question, one is expected to find the angle between u and v, and to get this angle, I will use the triangle formula.
|u-v|^2 = |u|^2 + |v|^2 - 2*|u|*|v|*cosθ
(2√2)² = (2√2)² + (2√2)² - 2(2√2)*(2√2)*cosθ
Expanding (2√2)² = (2√2)*(2√2) = 2*2*2 = 8
8 = 8 + 8 - 16*cosθ
8 = 16 - 16*cosθ
8 - 16 = -16*cosθ
-8 = -16*cosθ
cosθ = 8/16 = 1/2 = 0.5
θ = cos^(-1) (0.5)
θ = π/3
The angle between u and v is π/3 and parallel-to u plus v parallel-to = k*(u+v) (where k=const)
two angles from a linear pair. the measure of one angle is 2/3
Answer:
First angle = 117 degrees.
Second angle = 63 degrees.

boy scout has 3 meters of rope. he cuts the rope into cords 3/5m long. how many cords will he make
Answer: 5 pieces
===================================================
Explanation:
Note how
(number of pieces)*(length per piece) = 5*(3/5) = 15/5 = 3
which is the total length of the original rope.
So that's why the answer is 5.
We can get this answer through either guess and check, or we can divide 3 over 3/5 like so
3 divide 3/5 = (3/1) divide by (3/5) = (3/1)*(5/3) = 15/3 = 5
The second fraction 3/5 flips when we divide by it. Also the division changes to a multiplication when we flip the second fraction.

Answer: 1 or 6/6
Step-by-step explanation:
Order of operations rules require that we multiply and divide before carrying out addition and subtraction.
Thus, we simplify 2/3 / (-4) first, obtaining -1/6.
Then we have -1/6 - 1/6 + 8/6, which combines to 6/6, or just 1.

For a charity event, raffle tickets are printed such that they have a vowel (excluding y) as the first character and a prime number less than 10 as the second digit. (Note that 1 is not a prime number.) The probability that the winning ticket has the vowel contained in the word event and the digit is the number of letters in the word event is
Answer:
P=5%
Step-by-step explanation:
In order to solve this problem, we can use the following formula for the probability of two independent events:
P(A and B)=P(A)*P(B)
so we need to find the probability for each event to happen.
They are asking for the probability that the winning ticket will have the letter e on it. There are 5 vowels in the alphabet (a, e, i, o and u). Therefore the probability for the first letter to be e is:
P (A) = desired/total
P(A) = 15
We also know there are 4 prime numbers between 0 and 10 (2, 3, 5, 7) so the probability for the number to be a 5 is:
P (B) = 1/4
so the probability of getting a ticket that starts with an e and ends with a 5 is:
P(A and B)=P(A)*P(B)
P (AandB) = (1/5) ( 1/4 )
P (AandB) = 1/20
so the probability is 5%

There is no smallest positive rational number because, if there were, then it could be divided by two to get a smaller one. EXPLAINED
Answer:
Since a/2⁽ⁿ ⁺ ¹⁾b < a/2ⁿb, we cannot find a smallest positive rational number because there would always be a number smaller than that number if it were divided by half.
Step-by-step explanation:
Let a/b be the rational number in its simplest form. If we divide a/b by 2, we get another rational number a/2b. a/2b < a/b. If we divide a/2b we have a/2b ÷ 2 = a/4b = a/2²b. So, for a given rational number a/b divided by 2, n times, we have our new number c = a/2ⁿb where n ≥ 1
Since [tex]\lim_{n \to \infty} \frac{a}{2^{n}b }[/tex] = a/(2^∞)b = a/b × 1/∞ = a/b × 0 = 0, the sequence converges.
Now for each successive division by 2, a/2⁽ⁿ ⁺ ¹⁾b < a/2ⁿb and
a/2⁽ⁿ ⁺ ¹⁾b/a/2ⁿb = 1/2, so the next number is always half the previous number.
So, we cannot find a smallest positive rational number because there would always be a number smaller than that number if it were divided by half.

Andrey works at a call center, selling insurance over the phone. While debating over which greeting he
should use when calling potential customers - "Howdy!" or "Hiya!" - he decided to conduct a small study.
For his subsequent 500 calls, he chose one of the greetings randomly by flipping a coin. Then, he compared
the percentage of calls he succeeded in selling insurance using each greeting.
What type of a statistical study did Andrey use?
Choose 1 answer:
Sample study
Experiment
Observational study
Answer:
The answer would be Experiment and A
Step-by-step explanation:
I got it correct
Based on the description of the study embarked upon by Audrey, it can be concluded that the statistical study carried out is an experimental study.
Experimental studies involves the introduction of a treatment on the participants in and then measuring how the participants respond to the treatment given.
Here, the greeting types could be regarded as the treatment as are expected to cause a change in the responses of the customers.
Observational study on the other hand, studies natural effect without trying to influence anything in the process.
Therefore, the experiment could best be attributed as an experimental study.
