Answer:

0.005371

Step-by-step explanation:

Given that a fair coin is tossed 11 times.

Since coin is fair probability for head p = 0.5 and q = prob for tail =0.5

Each trial is independent of the other. Hence X no of heads is binomial with n = 11 and p =0.5

Prob for getting 10 heads out of 11 tosses

=P(X=10)

=11C10 (0.5)^{10} (0.5)\\= 0.005371

For this case we have the following conversion of units:

1mi = 1609m

1h = 3600s

Thus, applying the conversion of units we have:

(23.35 \frac{mi}{h}) (\frac{1609}{1}\frac{m}{mi}) (\frac {1}{3600}\frac{h}{s}) = 10.4 \frac{m}{s}

Then, the distance traveled for 5 seconds is given by:

d = (10.4) (5)

d = 52m

Answer:

he has completed 52 meters of the 80-meter race

Please help solve: Graph y-4=2(x-2)
xeze [42]

Answer:

Graph y = 2x

Step-by-step explanation:

First, let's get the equation into standard form. Distribute the 2 on the right.

y-4=2x-4

Next, we want the variable "y" to be alone, so we at 4 to both sides.

y-4+(4)=2x-4+(4)\\\\y=2x

That is our equation in standard y = mx + b form. "m" is our slope, while "b" is our y-intercept. Above , we don't have a value for b, therefore the line passes through the origin.

We do, however, have a slope, which can be thought of as \frac{rise}{run} or rise over run. To represent this, we can rewrite our slope as:

y=\frac{2}{1}x

Meaning in each interval, the line goes up by 2 units, and moves forward by 1.

I need the answer please I don't know it
Vlad1618 [11]
Basically the question is asking you for the area of the triangle.
The formula to find the area of a triangle is base x height divided by 2.
So in this case you would do 27 x 15.5 = 418.5
Now you divide by 2 (209.25)
So the answer is D. Hope this helps!!
