PSYCHO15rus [73]3 years ago
3 0

Step-by-step explanation:

81 - 1.2x < 55

81 < 55 + 1.2x (add 1.2x to both sides)

1.2x > 26 (subtract 55 from both sides)

x > 21 2/3.

g When a pair of dice is rolled there are 36 different possible outcomes: 1-1, 1-2, ... 6-6. If a pair ofdice is rolled 3 times,
Stolb23 [73]

Answer:

1/12 is the probability of getting sum of 4 everytime

Step-by-step explanation:

The Probability of getting the sum of 4 when a dice is rolled is 1/12. In a sample space of 36, only 3 occurrence lead to sum of 4 (1,3) (2,2) and (3,1).

For each time the dice is rolled, the Probability of sum 4 is 1/12.

mafiozo [28]

Answer:

A) zero; cannot

Step-by-step explanation:

In line with the principle of rational expectations, expectation errors are unpredictable. The expectations of all available information will not differ from the optimal projections.The word optimal projection is inexorably intertwined with the best guess in rational expectations theory.

The graph of function f is shown on the coordinate plane. Graph the line representing function g, if g is defined as shown below
Aleonysh [2.5K]

Answer:

g(x)=x-1

Step-by-step explanation:

Any problem of this kind should first be approached by solving the initial function.

This question is based on curve translation on x-axis. But, there can be questions asked on translation in both axes, rotation of curve about origin, or both combined.  

Initial function f(x) is a straight line from picture.

Common equation of straight line is

y=mx+c

m= slope of the line

c= y-intercept

Slope of the line:

m=\frac{y_{2}-y_{1} }{x_{2}-x_{1}}

Let those points on graph be A(3,0) and B(0,-6)

Therefore, slope of line AB, using formula is:

m=\frac{0-(-6)}{3-0}

m=2

And c=(-6)

And equation of line AB is:

y=2x-6

f(x)=2x-6

Now this line is translated backwards by 2 units, (x) becomes (x+2)

Let us consider a X, such that, X=x+2

f(X)=2X-6

f(x+2)=2(x+2)-6

f(x+2)=2x+4-6

f(x+2)=2x-2

Now, there is another function such that, g(x)= \frac{1}{2} f(x+2)

g(x)= \frac{1}{2}(2x-2)

g(x)= x-1 ; according to your question.

In the picture, they are asking for a function, g(x)= \frac{-1}{2} f(x+2)

Then, g(x)= -x+1 ; according to the picture.

Here, I have attached a file showing all the graphs for clear understanding.

Hello!

To find the slant height you use the equation

a^2 + b^2 = c^2

a is radius
b is height
c is slant height

Put in the values you know

9^2 + 17^2 = c^2

square the numbers

81 + 289 = c^2

Add

370 = c^2

Take the square root of the number

19.2 = c

The answer is B)19m

Hope this helps!
