scientific notions have to be less than 10 and more than 1

1. 68600 / 10000 = 6.86

A. 6.86 x 10^4

2. 0.082 x 100 = 8.2

C. 8.2 x 10^-2

3. 0.068 x 100 = 6.8

D. 6.8 x 10^-2

6x^2 + 66x + 60 factor completely

kiruha [24]

Hi! Let me help you!

Remember, factoring looks like so:
ab+ac=a(b+c)
So, we need to find the greatest common factor (G.C.F.) of the polynomial.
In this case, 6 is the GCF, so we factor it out:
6x²+66x+60
Divide 6, 66 and 60 by 6:
x²+11x+10

<u>Answer:</u>

x²+11x+10

Hope you find it helpful.

How can I use the figure to find the exact value of sin 2theta?

Iteru [2.4K]

Answer:

sin(2θ) = 24/25

Explanation:

In order to find the value of sin 2θ, first, recall the double-angle formula for sine.

$\sin 2\theta=2\sin \theta\cos \theta$

From the right-triangle:

$\begin{gathered} \sin \theta=\frac{\text{Opposite}}{\text{Hypotenuse}}=\frac{3}{5} \\ \cos \theta=\frac{\text{Adjacent}}{\text{Hypotenuse}}=\frac{4}{5} \end{gathered}$

Substitute these values into the double-angle formula obtained earlier.

$\begin{gathered} \sin 2\theta=2\sin \theta\cos \theta \\ =2\times\frac{3}{5}\times\frac{4}{5} \\ =\frac{24}{25} \end{gathered}$

The exact value of sin(2θ) is 24/25.

Recently many companies have been experimenting with telecommuting, allowing employees to work at home on their computers. Among

Paha777 [63]

Answer:

A.) Population : All employees at a firm

B.) μ = 5.4

C.) Sample : 80 employees at a firm

D.) Sample mean, x bar = 4.5

Step-by-step explanation:

From the question :

E.)

H0: μ ≥ 5.4

H1 : μ < 5.4

F.)

If Pvalue < α ; Reject H0

G.)

Test statistic :

(xbar - μ) ÷ (s/sqrt(n))

(4.5 - 5.4) ÷ (2.7/sqrt(80))

-0.9 ÷ 0.3018691

= - 2.98

H.)

Pvalue fro Zscore calculator, α = 0.10 = 0.002882

I.)

Decision :

0.002882 < 0.10

Since, Pvalue < α ; We reject the Null

J.)

We Can conclude that the true mean number of sick days for all employees of the firm has decreased after telecommuting was introduced
