Answer:

We think about ourselves way less than we think 8% of the time.

Step-by-step explanation:

In a self-awareness: introspection research study conducted by Mihaly Csikszentmihalyi and Thomas Figurski in 1982, to determine the degree to which people find out about themselves through the process of introspection (thinking about themselves).

The research involved an arrangement where participants were given beepers and asked to write down what they were thinking about when the beepers went off randomly throughout the day. The results indicated that "We think about ourselves way less than we think 8% of the time."

Step-by-step explanation:

Compare the equation to that of an ellipse with center (h, k) and axes of lengths 2a and 2b.

  ((x -h)/a)^2 +((y -k)/b)^2 = 1

We see that (h, k) = (4, 0) and a=2, b=3.

This tells us the center of the ellipse is (4, 0), the major axis is parallel to the y-axis, and the minor axis is parallel to the x-axis. The ellipse extends ±2 units from its center in the x-direction and ±3 units from its center in the y-direction.

Answer:

n = √108 or 6√3

Step-by-step explanation:

n is the altitude of the right triangle

Based on the right triangle altitude theorem, we would have:

h = √(xy)

Where,

h = n

x = 18

y = 6

Substitute

n = √(18*6)

n = √108

Or

n = 6√3

Answer:

436.42 m

Step-by-step explanation:

We are to determine the perimeter of the field

perimeter = perimeter of rectangle + perimeter of the two semicircles

Perimeter of a rectangle = 2 x (length + breadth)

2 x (82 + 53) = 270m

Perimeter of a semicircle = 1/2πD

perimeter of the 2 semicircles = 2 x (1/2 x 3.14 x 53) = 166.42

Perimeter = 270 + 166.42 = 436.42 m

Answer:

Step-by-step explanation:

The answer is no since f(-x) = f(x)

Example:

It is not one-to-one, it is two-to-one

Answer:

Well just looking at the choices can lead you to the answer right away.

Well since the probability of boys and girls are equal, its 50/50. And since 125 in half well about is about 60-62 and the minimum amount of girls has to be 70. It can’t be higher then half and the choices remain to less then half not including 50%. So that eliminates all 3 choices except B.

The probability that out of 125 babies born, at least 70 will be girls is 10.5%. So, option B is correct.

Probability is defined as the chance for an event to occur. The value of probability is expressed from zero to one.

Here,

Let X be the number of girls born among the babies.

Let the number of babies born be n = 125

Let the probability of girls being born be P

Since, boys and girls are equally probable, P = 1/2 = 0.5

The probability that at least 70 girls will be born is P(X ≤ 70)

P(X ≤ 70) = P(70) + P(71) + P(72) + P(73) + P(74) +....P(125)

Applying the binomial probability equation,

P(X) = {n!/[X!(n - X)!} Pˣ (1 -P)ⁿ⁻ˣ

So,

P(70) = {125!/[70!(125-70)!]}x 0.5⁷x (1 - 0.5)⁵⁵

We get P(70) = 0.02913

Using cumulative probability function, we get the probability upto X=125.

By adding all the values, we get,

P(70) = 0.1051

Therefore probability that at least 70 girls are born = 0.1051 x 100 = 10.5%

Hence,

The probability that out of 125 babies born, at least 70 will be girls is 10.5%.

Answer:

CI 98 %  =  ( 3.332  ;  5.668 )

t(c)  =  2.9979

Step-by-step explanation:

Confidence Interval  CI  98 %   then  α  =  2 %   α  =  0,02    α/2  =  0.01

Sample information:

Sample size    n  =  8

sample mean     x  =  4.5

standard deviation of sample    s  =  1.1 kg

degree of freedom     df  =  n  -  1     df  =  8  -  1    df  =  7

With    α/2  0.01  and  df  =  7 from t-studente table we find   t(c)

t(c)  =  2.9979

CI 98 %  =  (   x  ±  t(c) * s/√n )

CI 98 %  =  (  4.5  ±  2.9979 *  1.1/ √8 )

CI 98 %  =  (  4.5  ±  3.2976/2.8228 )

CI 98 %  =  (  4.5  ± 1.168 )

CI 98 %  =  ( 3.332  ;  5.668 )

Step-by-step explanation:

Answer:

n = -4

Step-by-step explanation:

Let's solve your equation step-by-step.

−2(n − 6) = 20

Step 1: Simplify both sides of the equation.

−2(n − 6) = 20

(−2)(n) + (−2)(−6) = 20(Distribute)

−2n + 12 = 20

Step 2: Subtract 12 from both sides.

−2n + 12 − 12 = 20 − 12

−2n = 8

Step 3: Divide both sides by -2.

Answer:

  40° 31' 39"

Step-by-step explanation:

Base-60 arithmetic is just like base-10 arithmetic in that you borrow the value of the base from the next-higher "digit" when you need to subtract a larger number from a smaller number.

  90 : 00 : 00 - 49 : 28 : 21  . . . . . we used a colon (:) to separate "digits"

  = 89 : 59 : 60 -49 : 28 : 21

  = 40 : 31 : 39

The measure of angle K is 40° 31' 39".

Answer:

C-15.12. That is the most suitable answer

Answer:

Step-by-step explanation:

To prove that the sum of the first n even +ve integers is:

[tex]\mathsf{2+4+6+8+ . . . +2n = n^2+ n }[/tex]

By using mathematical induction;

For n = 1, we get:

2n = 2 × 1 = 2

2 = 1² + 1 ----- (1)

∴ the outcome is true if n = 1

However, let assume that the result is also true for n = k

Now, [tex]\mathsf{2+4+6+8+. . .+2k = k^2 + k --- (2)}[/tex]

[tex]\mathsf{2+4+6+8+. . .+2k+2(k+1)}[/tex]

we can now say:

[tex]\mathsf{= (k^2 + k) + 2(k + 1)} \\ \\ \mathsf{= k^2 + k + 2k + 1}[/tex]

[tex]\mathsf{= (k^2 + 2k + 1) + (k + 1)}[/tex]

[tex]\mathsf{= (k + 1)^2 + (k + 1)}[/tex]

∴

[tex]\mathsf{2 + 4 + 6 + 8 + . . . + 2k + 2(k + 1) = (k + 1)^2 + (k + 1)}[/tex]

Thus, the result is true for n = m+1, hence we can posit that the result is also true for each value of n.

As such [tex]\mathsf{2+4+6+8+. . .+2n = n^2 + n }[/tex]

No.

Since w = 8, you must replace the variable with the number associated to it.

So, it would be 5 + 8 = 58

5 + 8 is not equal to 58, it is equal to 13.

If you wanted to find out what w was, simply subtract 5 on both sides.

Answer:

The hypotenuse is twice the length of the shortest side so;

A could be the answer as when 5 is shortest and 10 is hypotenuse we get 5√3 for the other side which = 8.6

It cannot be B, C or D as the numbers cannot be 2 values same as hypotenuse (the longer length) as 5 + 5 = 10 and we cant use 4 lengths in one triangle and either of 3 out of 4 values do not show ratio of lowest side any value middle value = LV +√3 and hyp LV(2)

so A is the answer.

Given:

The graph of function.

To find:

The correct statement for the domain and range of the given graph.

Solution:

Domain: The set of input values.

Range: The set of output value.

From the given graph it is clear that the graph represents a polynomial function.

The given graph of a polynomial function is defined for all real values of x. So, the domain is the set of all real numbers.

The graph of the function approaches from negative infinite to positive infinite. So, the output the given graph is set of all real numbers. It means the range is the set of all real numbers.

Therefore, the correct options are B and D.

The true statements are:

B. The range is the set of all real numbers.

D. The domain is the set of all real numbers.

From the figure, we can see that the graph extends in all directions without any end.

This means that, the graph of the function can take any real value as its input, and output

Hence, the domain and the range of the graph are set of all real numbers
