I think it is 40 percent of1,000

40% of a 1000 equals 40/100 multiplied by 1000. This simplifies to 4/10 multiplied by 1000, which equals 400.

One quarter of 1200 equals 1/4 multiplied by 1200, which equals 300.

So we can see that 40% of 1000 is greater then one quarter of 1200.

(x, 7) and (11, 8); m = -1/5<br> Plz help
Kay [80]

Answer:

This tells us that the line with slope -1/5 passes through the two points (16, 7) and (11, 8).  The previously unknown x-coordinate is 16.

Step-by-step explanation:

A line with slope m = -1/5 passes through the points (x, 7) and (11, 8).  Find the value of x.

The slope of the line through these two points is found from the slope formula and is:

        8 - 7

m = ----------- and the value of m is given as -1/5.  Therefore,

         11 - x

           1

m = ----------- =  -1/5

         11 - x

Cross-multiplying, we get (1)(5) = -(11 - x), or 5 = -11 + x.  Then x = 16

This tells us that the line with slope -1/5 passes through the two points (16, 7) and (11, 8).  The previously unknown x-coordinate is 16.

Use the unit circle to find the inverse function value in degrees.<br> tan^-1 sqrt 3
mr Goodwill [35]
Use the unit circle to find the inverse function value in degrees.tan^-1 sqrt 3

The correct answer would be 60 degrees. Since you are asked to find an angle that the tangent is equal to sqrt 3. The only angle that is equal to that given the interval is 60 degrees. So that is the correct answer. I hope this answer helped you.

You throw two four-sided dice. Let the random variable X represent the maximum value of the two dice. Compute E(X). Round your a
Troyanec [42]

Answer:

E(X)=3.125

Step-by-step explanation:

We are given that two four sided dice.

Then , the sample space

{(1,1),(1,2),(1,3),(1,4),(2,1),(2,2),(2,3),(2,4),(3,1),(3,2),(3,3),(3,4),(4,1),(4,2),(4,3),(4,4)}

Total number of outcomes=16

Let the random variable X represent the maximum value of the two dice

Outcomes                            X                                 P(X)

(1,1)                                          1                                 1/16

(1,2),(2,1),(2,2)                                   2                        3/16

(1,3),(2,3),(3,1),(3,2),(3,3)                    3                           5/16  

(1,4),(3,4) ,(2,4),(4,1),(4,2),(4,3),(4,4)    4                            7/16

Using the probability formula

P(E)=\frac{Favorable\;outcomes}{Total\;number\;of\;outcomes}

Now,

E(X)=\sum_{i=1}^{n}x_iP(x_i)

E(x)=1(1/16)+2(3/16)+3(5/16)+4(7/16)

E(x)=\frac{1+6+15+28}{16}

E(x)=\frac{50}{16}=3.125
