Round your answers to four decimal places. a. What is the probability the fatality resulted from a fall
Answers
Answer:
0.1634 = 16.34% probability the fatality resulted from a fall
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question, we have that:
1795 + 837 + 741 + 645 + 404 + 113 = 4535 total fatalities.
Of those, 741 from falls.
741/4535 = 0.1634
0.1634 = 16.34% probability the fatality resulted from a fall

How much does 2.5 L of oil cost if 2,000 mL costs $5.00?
Show work
Answers
Answer:
$6.25
Step-by-step explanation:
2000ml = 2 litres
2.5L - 2L = 500ml
So now we know that without the 500ml, it is 5 dollars.
Find out how much 500 ml cost.
2000ml = 5.00
1ml = 5.00 ÷ 2000 = 0.0025
500ml = 0.0025 x 500 = 1.25
2L + 500 ml = 2.5L (which 2.5L costs 6.25)

A suitcase is 27 inches long and
24 inches wide. What is the
diagonal length of the suitcase?
Answers
Answer:
The diagonal is 30 inches
step-by-step explanation:
The diagonal is 30 inches
Step-by-step explanation:
Assuming a rectangular suitcase (with right angles), we can use the Pythagorean theorem to solve this
a² + b² = c²
so we plug our two values to find the diagonal (hypotenuse)
24² + 18² = c²
576 + 324 = c²
900 = c²
c = √900
c = 30
The diagonal is 30 inches
(T & G) -> (E v D) what does this mean
Answers
Answer:
The work done by the electric field in Figure 1 to move a positive charge q from A, the positive plate, higher potential, to B, the negative plate, lower potential, is
W = −ΔPE = −qΔV.
The potential difference between points A and B is
−ΔV = −(VB − VA) = VA − VB = VAB.
Entering this into the expression for work yields W = qVAB.
Work is W = Fd cos θ; here cos θ = 1, since the path is parallel to the field, and so W = Fd. Since F = qE, we see that W = qEd. Substituting this expression for work into the previous equation gives qEd = qVAB.
The charge cancels, and so the voltage between points A and B is seen to be

What are coordinates?A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.
Given, point is located at (4, –2)
Since on the option distance given is from Origin points,
Since we know in coordinates Plane.
X = 4 would be at 4 units right of the origin
y = -2 would be at 2 units down of the origin.
Thus point (4, -2) will be 4 units right and 2 units down from the origin.

On an American League baseball team with 15 field players and 10 pitchers, the manager must select for the starting line-up, 8 field players, 1 pitcher and 1 designated hitter. A starting line-up specifies the players for these positions and the positions in a batting order for the 8 field players and designated hitter. If the designated hitter must be chosen among all the possible field players, how many possible starting line-ups are there.
Answers
Answer:
There are 18,162,144,000 possible starting line-ups
Step-by-step explanation:
The order in which the player are chosen is important, as if two player exchange places, we have a new batting order. So we use the permutations formula to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]
In this question:
Batting order:
9 batters(8 field + the designated hitter) from a set of 15. So
[tex]B = P_{(15,9)} = \frac{15!}{(15-9)!} = 1816214400[/tex]
Pitcher:
1 from a set of 10. So
[tex]P = P_{(10,1)} = \frac{10!}{(10-1)!} = 10[/tex]
Total:
[tex]T = B*P = 1816214400*10 = 18162144000[/tex]
