The correct option is the third one. In this situation, x+1 being inside "parentheses" indicates that the 1 shifts the graph horizontally, which eliminates option one. Although it states x+1, graphically this implies the opposite shift. Typically, one would expect to move right by one, but due to the "opposite" sign, it actually translates to a leftward movement by one. (Mathematics can be perplexing; I'm not sure why)

About ten percent of users do not close Windows properly. Suppose that Windows is installed in a public library that is used by
lawyer [12517]

Answer:

Refer to the explanation

Step-by-step explanation:

As approximately 10% of users fail to close Windows properly, we determine:

  • The likelihood that a user neglects to shut down Windows correctly is p=0.1;
  • The likelihood that a user shuts the Windows properly is q=1-p=1-0.1=0.9.

A. On average,

  • one in ten users does not close Windows correctly;
  • 10 out of 100 users fail to close Windows correctly.

B. The likelihood that precisely 8 out of the next 10 users will close Windows correctly is

C^{10}_8\cdot q^{8}p^{10-8}=\dfrac{10!}{8!(10-8)!}\cdot (0.9)^8\cdot (0.1)^2=45\cdot (0.9)^8\cdot (0.1)^2\approx 0.1937

Leona [12618]

Answer:

The earnings gap, over a career spanning 30 years, between men and women totals $1,200,150

Step-by-step explanation:

Calculated annually.

The typical male earns $90,761 each year.

The typical female earns $50,756 per annum.

Therefore, the annual difference is:

90,761 - 50,756 = 40,005

Across 30 years:

30*40,005 = 1,200,150

The earnings gap over a 30-year career, when comparing men and women, is $1,200,150

Result:

20.19°

Detailed explanation:

Refer to the attached diagram related to the question. We need to determine <CAB

Utilizing the sine rule on triangle ABC:

\frac{4.5}{sin15^0} = \frac{6}{sin

cross-multiply

4.5 * sin

Thus, the angle <CAB measures 20.19°

60 more than nine times a number is the same as two less than 10 times the number what is the number
PIT_PIT [12445]

Let's tackle your equation step-by-step.

9x+60=10x−2

Step 1: Subtract 10x from each side.

9x+60−10x=10x−2−10x

−x+60=−2

Step 2: Subtract 60 from each side.

−x+60−60=−2−60

−x=−62

Step 3: Divide both sides by -1.

−x /−1 = −62 /−1

x=62

I hope this was helpful! Please consider giving me Brainliest!!
