Answer: plane a is faster than plane b because it has more speed than plane b

Step-by-step explanation:

Country B is more efficient than Country A when it comes to producing cars and tanks.

Country A takes twice as long to produce a car (30 minutes) than Country B (12 minutes). However, Country A takes 20 minutes to produce a tank while Country B takes 10 minutes, cutting the amount of time in half.

We can measure the efficiency of each country by calculating the number of cars and tanks each country can produce in an hour. We can do this using the following formula:

Cars per hour = (60 minutes/minutes to produce car)

Tanks per hour = (60 minutes/minutes to produce tank)

For Country A, the number of cars produced in an hour is (60 minutes/30 minutes) = 2 cars per hour and the number of tanks produced in an hour is (60 minutes/20 minutes) = 3 tanks per hour.

For Country B, the number of cars produced in an hour is (60 minutes/12 minutes) = 5 cars per hour and the number of tanks produced in an hour is (60 minutes/10 minutes) = 6 tanks per hour.

Therefore, Country B is more efficient than Country A when it comes to producing cars and tanks.

The value of x, y, and z in the rhombus are -114, 7 and 59 respectively

Since the opposite angles of a rhombus are equal to each other. We can write:

(-x-10)° = 104°

-x-10 = 104

-x = 104 + 10

x = -114

Since the adjacent angles in rhombus are supplementary. We have:

114 + (z + 7) = 180

121 + z = 180

z = 180 -121

z = 59

104  + (10y + 6) = 180

110 + 10y = 180

10y = 180 - 110

10y = 70

y = 70/10

y = 7

Thus, the value of x, y, and z are -114, 7 and 59

Here to solve the probability of this sum, it is difficult to say that the probability without no information.

(a)The probability that the team wins the debate with a junior giving the closing argument is 0.083.

(b) To design a simulation to estimate the probability that a sophomore is never selected to give the closing argument in the next 3 debates, one could randomly assign a closing argument speaker for each debate using a table of random digits. The table would have two columns: one for sophomores and one for juniors and seniors. The probability of a sophomore being selected would be 20%, and the probability of a junior or senior being selected would be 80%. The simulation would be run for 3 debates and the number of times a sophomore is never selected would be recorded. This process would be repeated a number of times to estimate the probability of a sophomore never being selected. (e) Based on the dot plot, it appears that there is some evidence that the sophomores were purposely ignored, as there are several simulated sets of 5 debates where a sophomore was not selected to give the closing argument. However, without more information, it is difficult to say for certain if this is enough evidence to support the claim that the sophomores were purposely ignored.

A larger sample size or a more detailed analysis of the simulation results may be needed to make a more convincing determination.

The probability that a teenage boy has a cholesterol level greater than 200 is 0.33: Option D

It is the chance of occurrence of an event E

To solve this problem you must first find the z-score associated with a cholesterol level greater than 200.

The general formula for a z score is:

z = (x-µ)/σ

Where z is the z score, x is the data point, µ is the mean, and σ is the standard deviation. With your numbers that would become:

z = (200-170)/30

z = 1.833

If you are using a graphing calculator, such as the TI-83 Plus, you can then go to 2nd vars, and the second option is normalcdf

To use normalalcdf enter normalcdf (lower z score, upper z score) in your case normalcdf (1.833, 1E99) to get the probability that a teenage boy has a cholesterol level greater than 200 Which will give you .0337.

If you are using a z table, find the probability associated with your z score of 1.83, and subtract that from 1. You subtract from 1 because a z table gives you the probability of a score being below the one you obtained.  

This implies therefore that the probability is 0.337

The range of the function (f+g)(x) = x² - 1 will be ( -1, ∞ ). The correct option is B.

The range of values that we are permitted to enter into our function is known as the domain of a function.

The x values for a function like f make up this set (x). A function's range is the set of values it can take as input. After we enter an x value, the function outputs this set of values.

Given that the function is f(x) = x²+2x-5. The function g(x) will be calculated by the data given in the table.

x           -6    -3     -1    4

g(x)       16    10    6   -4

The function g(x) will be:-

g(x) = mx + c

No S with sum greater than 61 is possible and 61 is indeed the maximum.

By using the greedy algorithm, we obtain 61, with S={15,14,13,11,8}.

We must now prove that no such set has sum greater than 61. Suppose such a set [tex]$S$[/tex] existed. Then [tex]$S$[/tex] must have more than 4 elements, otherwise its sum would be at most 15+14+13+12=54.

S can't have more than 5 elements. To see why, note that at least.

[tex]$\left(\begin{array}{l}6 \\ 0\end{array}\right)+\left(\begin{array}{l}6 \\ 1\end{array}\right)+\left(\begin{array}{l}6 \\ 2\end{array}\right)+\left(\begin{array}{l}6 \\ 3\end{array}\right)+\left(\begin{array}{l}6 \\ 4\end{array}\right)=57$[/tex] of its subsets have at most four elements (the number of subsets with no elements plus the number of subsets with one element and so on), and each of them have sum at most 54. By the Pigeonhole Principle, two of these subsets would have the same sum. If those subsets were disjoint, we would directly arrive at a contradiction; if not, we could remove the common elements to get two disjoint subsets.

Thus, [tex]$S$[/tex] would have to have 5 elements. [tex]$S$[/tex] contains both 15 and 14 (otherwise its sum is at most 10+11+12+13+15=61.

It follows that [tex]$S[/tex] cannot contain both a and a-1 for any [tex]$a \leq 13$[/tex], or the subsets {a,14} and {a-1, 15} would have the same sum. So now [tex]$S$[/tex] must contain 13 (otherwise its sum is at most 15+14+12+10+8=59, and S cannot contain 12, or the subsets, {12,15} and {13,14} would have the same sum.

Now the only way [tex]$S$[/tex] could have sum at least 62=15+14+13+11+9

would be if S={15,14.13,11.9}. But the subsets {9,15} and {11,13} have the same sum, so this set does not work.
