Consider this equation.
cos(0)= -2√5/5
If 0 is an angle in quadrant II, what is the value of sin(0)?
Answer:
I hope this can help
Step-by-step explanation:
The value of sin(0) should be considered as the [tex]\sqrt{5} \div 5[/tex]
Calculation of the value of sin(0):Since the equation is [tex]cos(0)= -2\sqrt 5/5[/tex]
Also in the case when 0 is an angle in quadrant II
So based on this, we can say that value of sin(0) should be considered as the [tex]\sqrt{5} \div 5[/tex]

A wheel assembly is
made from 2 wheels,
each weighing 2.6
pounds, and a steel
axle, which weighs
1.8 pounds. What is
the total weight of
the assembly?
Answer:
The total weight of the assembly is 7 pounds.
Step-by-step explanation:
The total weight of the assembry is found by the sum of the weights of each components.
We have:
2 wheels, each weighing 2.6 pounds, so 2*2.6 = 5.2 pounds
An axle, which weighs 1.8 pounds, so 5.2+1.8 = 7 pounds
The total weight of the assembly is 7 pounds.

Christopher wants to estimate the mean amount of carbon dioxide that is emitted by burning 1\text{ L}1 L1, start text, space, L, end text of a new type of gasoline. He plans on burning 1\text{ L}1 L1, start text, space, L, end text at a time and measuring the resulting emissions. He'll repeat this process for a sample of nnn attempts and construct a confidence interval for the mean. He wants the margin of error to be no more than 202020 grams at a 90\%90%90, percent level of confidence. Preliminary data suggests that \sigma=50σ=50sigma, equals, 50 grams is a reasonable estimate for the standard deviation of the emissions from burning 1\text{ L}1 L1, start text, space, L, end text of this type of gasoline. Which of these is the smallest approximate sample size required to obtain the desired margin of error?
Answer:
The smallest sample size required to obtain the desired margin of error is of 17.
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1-0.9}{2} = 0.05[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1-\alpha[/tex].
So it is z with a pvalue of [tex]1-0.05 = 0.95[/tex], so [tex]z = 1.645[/tex]
Now, find the margin of error M as such
[tex]M = z*\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
Which of these is the smallest approximate sample size required to obtain the desired margin of error?
The desired margin of error is 20, so [tex]M = 20[/tex]
We have that [tex]\sigma = 50[/tex].
The smallest sample size is n. So
[tex]M = z*\frac{\sigma}{\sqrt{n}}[/tex]
[tex]20 = 1.645*\frac{50}{\sqrt{n}}[/tex]
[tex]20\sqrt{n} = 50*1.645[/tex]
[tex]\sqrt{n} = \frac{50*1.645}{20}[/tex]
[tex](\sqrt{n})^2 = (\frac{50*1.645}{20})^2[/tex]
[tex]n = 16.9[/tex]
Rounding up
The smallest sample size required to obtain the desired margin of error is of 17.

Find the y-intercept. 4) 4x + 3y=-3 A) -3 B) 3 C) -5/2 D) -2/5
Answer:
Please check the explanation.
Step-by-step explanation:
Given the equation
[tex]4x + 3y=-3[/tex]
We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.
Thus,
substituting x = 0 in the equation
[tex]4x + 3y=-3[/tex]
[tex]4(0) + 3y = -3[/tex]
[tex]0+3y = -3[/tex]
[tex]3y = -3[/tex]
divide both sides by 3
[tex]\frac{3y}{3}=\frac{-3}{3}[/tex]
Simplify
[tex]y = -1[/tex]
Therefore, the y-intercept is: -1
Note: it seems that you did not add the right option to chose.

will and olly share £80 in the ratio 3 : 2
Answer:
Will's share = 48
Olly's share = 32
Step-by-step explanation:
Will's share : Olly's share = 3:2
Will's share = 3x
Olly's share = 2x
3x + 2x = £ 80 {Combine like terms}
5x = 80 {Divide both sides by 5}
x = 80/5
x = 16
Will's share = 3x = 3*16 = 48
Olly's share = 2x = 2*16 = 32
IQ scores are normally distributed with a mean of 100 and a standard deviation of 15. Mensa is an international society that has one and only one qualification for membership: a score in the top 2% on an IQ test. a. What IQ score should one have in order to be eligible for Mensa
Answer:
130.81
Step-by-step explanation:
We solve this question using z score formula
z = (x-μ)/σ,
where from the question:
x is the raw score = ?
μ is the population mean = 100
σ is the population standard deviation = 15
We are told in the question that:
Mensa is an international society that has one and only one qualification for membership: a score in the top 2% on an IQ test.
The top 2% means a score in the 98th percentile
The z score of the 98th percentile = 2.054
Hence:
2.054 = x - 100/15
Cross Multiply
2.054 × 15 = x - 100
30.81 = x - 100
x = 30.81 + 100
x = 130.81
The IQ score that one should have in order to be eligible for Mensa is the score of 130.81

Randomly select a customer that is a frequent shopper at our store. Randomly select a customer who does not know the store's location. Are these events mutually exclusive
Answer:
Yes, the events are mutually exclusive.
Step-by-step explanation:
Mutually exclusive events are events that can not occur at the same time.
For example: Turning left and turning right at the same time is not possible so the event is Mutually Exclusive.
Now consider the given information.
Randomly select a customer that is a frequent shopper at our store and randomly select a customer who does not know the store's location are mutually exclusive.
Because the customer either knows the location or not.
Yes, the events are mutually exclusive.
