Check the picture below.

\textit{area of a trapezoid}\\\\ A=\cfrac{h(a+b)}{2}~~ \begin{cases} h=height\\ a,b=\stackrel{parallel}{sides}\\[-0.5em] \hrulefill\\ h=8\\ a=14\\ b=8 \end{cases}\implies \begin{array}{llll} A=\cfrac{8(14+8)}{2}\implies A=4(22) \\\\\\ A=88 \end{array}

Event A: The sum is greater than 5.There are 10 sums equal to 5 or less. Therefore there are 26 sums greater than 5.P = 26/36
Event B: The sum is divisible by 4.The sums that are divisible by 4 are the<span> three</span> 4's, five 8's, and the <span>one </span>12.That means there are nine sums divisible by 4. P = 9/36

Round 4.028 to the nearest tenth.
Shalnov [3]

Answer:

4.0

Step-by-step explanation:

Look at the decimal place next to the tenths place. It has a 2 in its place. The rule for rounding is that any number 4 or lower is rounded down. Any number 5 or above is rounded up. The number is 2, which is below 4, so we round down. The tenths place would stay the same because it can't get any smaller. Therefore, 4.028 is rounded down to 4.0

The point P(8, −3) lies on the curve y = 3/(7 − x). (a) If Q is the point (x, 3/(7 − x)), use your calculator to find the slope
yan [13]

Answer:

Slope of the line PQ is -63.434948.

Step-by-step explanation:

Given that,

The point P(8,-3) lies on the curve y=\frac{3}{7-x}.

If Q is the point lies on (x,\frac{3}{7-x} ).

To find:- Find the slope of line PQ.

So,  

The coordinates of point Q when it lies on (x,\frac{3}{7-x} )

        if x=1 then y= \frac{3}{7-1} =\frac{3}{6} =\frac{1}{2}

       So,   Q ≡ (1,\frac{1}{2} ) and many points can be calculated by given Equation.

Using the formula when two points (x_{1} ,y_{1} ) \& (x_{2}, y_{2}  ).

                Slope=Tan\theta = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

Then, substituting the coordinates we get,

             Slope = \frac{1-8}{\frac{1}{2}-(-3) }

             Slope = \frac{-7}{\frac{1}{2}+3 } = \frac{-7}{\frac{7}{2} }

             Slope = \frac{-14}{7}=-2

              tan\theta=-2   ⇒  \theta = tan^{-1} (-2)

               \theta= -63.434948

Therefore,

Slope of the line mPQ is -63.434948.
