<h2>Answer:</h2>

The statement that best describes the experimental probability of getting heads is:

It is 10% higher than the theoretical probability.

<h2>Step-by-step explanation:</h2>

We know that the theoretical probability of getting head is: 0.5

and the theoretical probability of getting tail is: 0.5

Also, the results of experiments are:

Heads Tails

90 60

This means that the experimental probability of getting head is: 90/150=3/5=0.6

and the experimental probability of getting tail is: 60/150=2/5=0.4

Hence, the experimental and theoretical probability of getting head is not same or equal.

Also, the experimental probability of getting head is more than the theoretical probability of getting head and the percent increase is calculated as:

$(0.6-0.5)\times 100\\\\\\=(0.1)\times 100\\\\=10\%$

Answer:

Its 10% higher than theoretical

Step-by-step explanation:

90/150 x 100= 60%

60-50=10

Towns X, Y, and Z are on the same straight road. Town Y is between Town X and Town Z. Town X is 57 miles from Town Z, and Town Y

Ray Of Light [21]

The distance between town X and Town Y is equal to the difference between the distance between Town X and Town Z and the distance from Town Y and Town Z. Mathematically
d (X-Y) = d (X-Z) - d(Y-Z)
Substituting,
d(X-Y) = 57 miles - 28 miles = 29 miles
Thus, the distance from Town X to Town Y is 29 miles.

Where do I place the coordinates for -2x-5 and -x-4

Maslowich

Step-by-step explanation:

you need to calculate coordinates first. just by having the function definitions you don't have any coordinates yet.

I typically pick x = 0 as a first point.

so, that gives

-2×0 - 5 = -5

as y result for the first line.

the point on line 1 is then (0, -5)

and we get -0 - 4 = -4 as y result for the second line.

the point for the second line is (0, -4)

for second points I typically go for x = 1.

for the first line we get

-2×1 - 5 = -2 - 5 = -7

and the second point is (1, -7) for the first line.

for the second line we get

-1 - 4 = -5

and the second point is (1, -5) for the second line.

so, make points on the chart for all 4 points, and connect them (and extend the connecting lines to the left and right to the end of the grid).

and the crossing point ?

that is where both equations deliver the same result.

so,

-2x - 5 = -x - 4

-x = 1

x = -1

and the y is then e.g. -2×-1 - 5 = 2 - 5 = -3

and the crossing point is (-1, -3)
