It would be 7(5) + 7(4) since u distribute the seven to both numbers and when do u multiply each separate before anything else

Write an expression using all six trigonometric functions such that the value of the expression is 3.
iren2701 [21]
The trig functions that you need to deal with are
Sine
Cosine
Tangent
Cotangent
Cosecant
Secant

You need to write a single expression using all six trig functions such that the value of the expression equals 3.

To make this as simple as possible, the first thing I would do is look up the values of these functions and identify which ones are equal to either 1/2 or 1.0 or 2.0

sin(30º) = 1/2
sin(90º) = 1
cos(0º) = 1
cos(60º) = 1/2
tan(45º) = 1
csc(30º) = 2
csc(90º) = 1
sec(0º) = 1
sec(60º) = 2
cot(45º) = 1

If we only had to use three trig functions (sin, cos, tan), one possibility is
tan(45º) + cos(0º)/sin(30º) = 1 + 1/(1/2) = 1 + 2 = 3
noticed how I chose one each of the required functions and the operations so that the result = 3.

Now it is up to you to figure out how to combine all six trig functions so that they equal zero. There are many possibilities for you to choose from..

what is the critical f-value when the sample size for the numerator is six and the sample size for the denominator is four? use
lubasha [3.4K]

The critical f-value when the sample size for the numerator and the  denominator is given using a two-tailed test will be 0.12 and 14.88.

We have,

The sample size for the numerator = 6,

i.e.

Numerator degree of freedom = 6 - 1 = 5,

And,

The sample size for the denominator = 4,

i.e.

Denominator degree of freedom = 4 - 1 = 3

And,

We have to use a two-tailed test,

So,

The significance level = \frac{0.10}{2} = 0.05

And,

Now,

The test follows the F-distribution with (5, 3) degrees of freedom,

Now,

Using the F-table at significance level 0.05 and check for given degrees of freedom,

We get,

Critical f-values : 0.12 and 14.88

Hence, we can say that the critical f-value when the sample size for the numerator and the  denominator is given using a two-tailed test will be 0.12 and 14.88.
