If sin θ = 0.57 then sin (π-θ)=?

1 answer:

8 0

In trigonometry laws, there's a equation to solve this problem :
sin (a-b) = sin(a) . cos(b) - sin (b) . cos(a),

so by assuming that a = π, b = θ, so the equation will be like this..
sin (π-θ) = sin(π) . cos(θ) - sin (θ) . cos(π),
= 0 . cos(θ) - sin(θ) . (-1)
= sin(θ) = 0.57

Hope this will help you :)

Which is an example of qualitative data?

spayn [35]

Answer:

Step-by-step explanation:

To answer this question, we have to familiar with the characteristics of qualitative data. Qualitative data is a type of data that is OBSERVED not measured. It corresponds to qualities of something. Qualitative data cannot be expressed in numerical form. It is usually collected through observation methods or interviews.

So from the above options,

Option A

The price of the last set of tires is a measurable quantity which can be expressed in numerical form. So it would not be the answer.

Option B:

The appearance of tires is a quality which can only be seen or observed but cannot be expressed in numerical form so it is the right answer for the question.

Option C & D:

The number of miles is a numerical quantity as it is measured so it will not be the correct answer to the question.

Solve for T<br> V = x + at

iris [78.8K]

Answer:

t=V‒x/a

Step-by-step explanation:

V=x+at (add ‒x in both side)

V‒x=x+at‒x

V‒x=at

V‒x/a=at/a

V‒x/a=t

so the formula is t=V‒x/a

Cardinals jerseys come in three different sizes, medium, large and extra large. A medium is x dollars, a large is $9 more than t

kicyunya [14]

Answer:

MEDIUM JERSEY =$21

Step-by-step explanation:

MEDIUM=$X ,LARGE =$X+9, EX LARGE=$X+15

9(X+9)+4(X+15)=414

9X+81+4X+60=414

13X=414-141

13X=273

X=21

Suppose that the average bill for the drive through of 24 customers at Burger Palace is $14.30. It is known that the population

Mice21 [21]

The standard deviation is a measure of a collection of values' variance or dispersion. The true mean bill for a customer at Burger Palace with 95% confidence is $13.38.

<h3>What is a standard deviation?</h3>

The standard deviation is a measure of a collection of values' variance or dispersion. A low standard deviation implies that the values are close to the set's mean, whereas a high standard deviation shows that the values are spread out over a larger range.

Given that the Sample mean ( $\overline x$ ) is $14.30, the Sample size(n) is 24 customers, the Standard deviation(σ) is 2.30, while for a 95% confidence interval the Z-score is 1.960. Therefore, the true mean can be written as,

$Z = \dfrac{\overline x- \mu}{\frac{\sigma}{\sqrt n}}\\\\\\1.960 = \dfrac{14.30-\mu}{\frac{2.30}{\sqrt{24}}}\\\\\\1.960 = \dfrac{14.3-\mu}{0.47}$

μ = 13.3788 ≈ 13.38

Hence, the true mean bill for a customer at Burger Palace with 95% confidence is $13.38.
