what scale of measurement is being used when a researcher measures the amount of car accidents that participants have been involved in during their lifetime?

Since the Pennsylvania lottery was rigged, the probability of drawing a 666 in the April 24th, 1980 drawing is 100%. The probability of drawing a 666 in the September 19th, 1980 Connecticut lottery, however, is extremely low, as it was not rigged and the odds of picking a specific 6-digit combination are 1 in 1 million.

To calculate this probability, you would take 1 divided by 1 million, which would be 0.000001. This means that the probability of drawing a 666 in the Connecticut lottery is 0.000001.   In conclusion, the probability of drawing a 666 in the April 24th, 1980 Pennsylvania lottery is 100%, while the probability of drawing a 666 in the September 19th, 1980 Connecticut lottery is 0.000001.

The number of trees on each acre of land, given that the trees are evenly spaced out, is 101 trees per acre

To find out how many trees are on each acre of land, we need to divide the total number of trees by the number of acres. This is given that the trees are spread out evenly as is the case here.

The number of trees per acre of land is therefore:

= Number of trees in total / Number of acres

The graph of x − 2 is a vertical line.

The graph of x − 2  is a straight line that is perfectly vertical, with no slope or angle. This line has an x-intercept of -2, meaning that the line crosses the x-axis at a point where x is equal to -2.

All points on the line have the same y-value, which is -2. This line extends infinitely in both directions and is a key example of a linear equation.

x − 2 is a linear equation, so its graph will be a straight line. In this case, the graph of x − 2 will be a vertical line that passes through the point (2, 0).

This is because when x is equal to 2, the equation will equal 0. As the x-value increases, the y-value will increase in a linear fashion, resulting in a vertical line.

The polynomial functions f(x) = x³-2x²-3x+6

To solve this question, we use the factor theorem, and using it, the polynomial function is: f(x) = x³-2x²-3x+6

The factor theorem means that if k is a root of f(x), f(k) = 0.

Thus, applying the factor theorem for this question, we have to choose the function for which:

f(2) =0, f(√3) =0, f(-√3) = 0

Function 1:

f(x) = x³-2x²-3x+6

Testing the values:

f(2( = 2³-2(2)²-3(2) +6

= 8--6+9 = 0

f(√3) = √3³-2(√3)²-3√3 +6

=3√3-3√3 = 0

f(-√3) = -√3³-2(-√3)²-3(-√3) +6

= -3√3-√3 = 0

Answer: 13/1560 (The distance flown in 13 hours is 1560 miles)

Step-by-step explanation: Rate X Time = distance

Therefore:

    r (rate) X 5 (hours) = 600 (distance)

    r = 600/5

    r = 120 miles per hour

    The rate of speed of the jet is 120 mph.

Then, to find out the distance flown in 13 hours:

    120 (rate) X 13 (time) = d (distance)

    120 X 13 = d

    1560 = d

    The distance flown in 13 hours is 1560 miles.

The smallest value of x for which the following inequality holds true is 7.

We are given

manipulating the inequality we get

1/3 +... + 1/x > 1

or, 1/4 + ... + 1/x > 2/3

or, 1/5 + .... + 1/x > 5/12

or, 1/6 + ... > 13/60

or, 1/7 + ... > 3/60

The probability that Ali's sum at least 6 is 0.996.

Sample space of rolling four fair six-sided dice:

= {(1, 1, 1, 1), (1, 1, 1, 2), ….., (6, 6, 6, 6)}

= 6^4

= 1296 ways

Favourable cases = {sum at least 6}

So, now we need to find the sums less than 6, which means the sum is either 4 or 5. Then, we will get:

(1, 1, 1, 1)

(1, 1, 1, 2)

(1, 1, 2, 1)

(1, 2, 1, 1)

(2, 1, 1, 1)

From above we know that only 5 ways will have the sums less than 6. So, the possible way of the sums at least 6 is:

= {sample space} – {the sums less than 6}

= 1296 – 5

= 1291

Thus, the probability P (sum at least 6) will be:

= 1291 / 1296

= 0.996

Hence, the probability that Ali's sum at least 6 is 0.996.

What is rotation?

A rotation is a transformation that turns the figure in either a clockwise or counterclockwise direction. You can turn a figure 90°, a quarter turn, either clockwise or counterclockwise. When you spin the figure exactly halfway, you have rotated it 180°. Turning it all the way around rotates the figure 360°.

This question is solved by applying a 270° clockwise about the origin, which has the following rule:

(x, y) = (-y, x)

Coordinate Q:

At the Figure, coordinate Q is Q(-4, 5). Applying the rule:

(-4, 5) = (-5, -4)

So the image of Q is Q'(-5, -4).

Coordinate R:

In Figure, the coordinate R is R(-2, 5). Applying the rule:

(-2, 5) = (-5, -2)

So the image of R is R'(-5, -2).

Coordinate S:
