Answer:

Option: B is the correct answer.

B. The complement of a set is the set of all outcomes not resulting in event.

Step-by-step explanation:

We know that generally complement of a some set is the list of the all elements that does not belong to that set.

i.e. it is the collection of the remaining elements that did not come in that set.

In probability the complement of a event means the set of all the outcomes that are not in that event.

           Hence, the answer is:

             Option: B

The value 5 is an upper bound for the zeros of the function shown below.
Mice21 [21]

Answer:

The given statement that value 5 is an upper bound for the zeros of the function f(x) = x⁴ + x³ - 11x² - 9x + 18  will be true.

Step-by-step explanation:

Given

f\left(x\right)\:=\:x^2\:+\:x^3\:-\:11x^2\:-\:9x\:+\:18

We know the rational zeros theorem such as:

if x=c is a zero of the function f(x),

then f(c) = 0.

As the f\left(x\right)\:=\:x^2\:+\:x^3\:-\:11x^2\:-\:9x\:+\:18 is a polynomial of degree 4, hence it can not have more than 4 real zeros.

Let us put certain values in the function,

f(5) = 448, f(4) = 126, f(3) = 0, f(2) = -20,

f(1) = 0, f(0) = 18, f(-1) = 16, f(-2) = 0, f(-3) = 0

From the above calculation results, we determined that 4 zeros as

x = -3, -2, 1, and 3.

Hence, we can check that

f(x) = (x+3)(x+2)(x-1)(x-3)

Observe that,

for x > 3, f(x) increases rapidly, so there will be no zeros for x>3.

Therefore, the given statement that value 5 is an upper bound for the zeros of the function f(x) = x⁴ + x³ - 11x² - 9x + 18  will be true.

Can anybody help this question?
Oxana [17]

Answer:

the first option

Step-by-step explanation:

really, just look at the table.

is the mean value (10.4) larger than the median (13.4) ?

I hope you can see right away that it is not.

and you can see they are not the same either.

so, all the answer options mentioning mean larger than median or equal to median can be ruled out right away.

so, it is between the first two options.

now think ! how do we draw number lines ? a coordinate axis ?

the smaller numbers left, the larger numbers right. the numbers grow from left to right.

the mean value is simply the sum of all measurements divided by the number of measurements (how many median were done). if that is smaller that the median (so, the Mean is left of the Median), it means that the majority of measurements had a result smaller (to the left) than the Median. so, it is skewed-left.

Solve for X<br><br> 2/3x+4=1/2x+5
mote1985 [20]

For this case we must find the value of the variable of the following equation:

\frac {2} {3} x + 4 = \frac {1} {2} x + 5

Subtracting \frac {1} {2} x from both sides:

\frac {2} {3} x- \frac {1} {2} x + 4 = 5\\\frac {4-3} {6} x + 4 = 5\\\frac {1} {6} x + 4 = 5

Subtracting 4 from both sides:

\frac {1} {6} {x} = 5-4\\\frac {1} {6} x = 1

Multiplying by 6 on both sides:

x = 6 * 1\\x = 6

Answer:

x = 6
