5.what number should be included in the data 2,8,7,4 and 9 so that the mean is 6

Answers

Answer:

Step-by-step explanation:

find mean of given numbers u notice that mean is actually 6 so no number is required to be included

Answer:

4. x = 35. Number 6 should be included

Step-by-step explanation:

Mean is the average

Data given:

14, 6, 2x, 8, 10, 4

The mean is

mean = sum of the data / number of data(14 + 6 + 2x + 8 + 10 + 4)/6 = 842 + 2x = 6*82x = 48 - 422x = 6x = 3

5. Let the added number is x, then the mean is:

(2 + 8 + 7 + 4 + 9 + x)/ 6 = 6x + 30 = 36x = 36 - 30x = 6

=> X - 2 = -8

=> X=(-6) - 2

=> -8

Answer:

x = -6

Step-by-step explanation:

x - 2 = -8

Add 2 to both sides to isolate the variable, x.

x - 2 + 2 = -8 + 2

-2+2 = 0

-8+2 = -6

Therefore,

x = -6

Check:

-6 -2 = -8

If the sales tax rate is 7% in New York, then how much sales tax would you pay in New York for a $34 pair of pants?

Answers

Answer:

$36.38

Step-by-step explanation:

If the sales tax rate is 7% in New York, then how much sales tax would you pay in New York for a $34 pair of pants?

Given data

Tax= 7%

Cost = $34

Let us solve for the amount of tax

=7/100*34

=0.07*34

=2.38

Hence the total is =2.38+34

=$36.38

Which inequality represents the stated situation : A theater is made to receive no more than 750 spectators. Group of answer choices

Answers

Answer:

C. s ≤ 750

Step-by-step explanation:

A. s≥750

B. s=750

C. s≤750

D. s<750

'no more than' in inequality means "less than or equal to"(≤) which means that the quantity could be less than or equal to.

From the question given, the theater can only receive less than 750 spectators or 750 spectators but no more than 750 spectators

The statement can be represented by the inequality;

s ≤ 750

rewrite sin^4x that involves only the first power of cos

Answers

Answer:

We want to rewrite:

sin^4(x)

in a way that only involves the first power of the cosine function.

We know that:

sin^2(x) = 1 - cos^2(x)

Then:

sin^4(x) = sin^2(x)*sin^2(x) = sin^2(x)*(1 - cos^2(x))

Now we know that:

cos(2x) = cos^2(x) - sin^2(x)

then

cos(2x) + sin^2(x) = cos^2(x)

We can replace that in our equation to get:

sin^2(x)*(1 - cos^2(x)) = sin^2(x)*(1 - cos(2x) - sin^2(x) )

sin^2(x)*(1 - cos(2x) - sin^2(x) ) = sin^2(x) - sin^2(x)*cos(2x) - sin^4(x)

then:

sin^4(x) = sin^2(x) - sin^2(x)*cos(2x) - sin^4(x)

sin^4(x) + sin^4(x) = sin^2(x) - sin^2(x)*cos(2x)

2*sin^4(x) = sin^2(x) - sin^2(x)*cos(2x) = sin^2(x)*(1 - cos(2x))

sin^4(x) = sin^2(x)*(1 - cos(2x))/2

So we rewrite the equation in such a way that we only have the first power of the cosine function.
