Answer:

Between 38.42 and 49.1.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

Approximately 68% of the measures are within 1 standard deviation of the mean.

Approximately 95% of the measures are within 2 standard deviations of the mean.

Approximately 99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean of 43.76, standard deviation of 2.67.

Between what two values will approximately 95% of the amounts be?

By the Empirical Rule, within 2 standard deviations of the mean. So

43.76 - 2*2.67 = 38.42

43.76 + 2*2.67 = 49.1

Between 38.42 and 49.1.

Answer:

The sample mean of failure time was of 49 hours.

The standard deviation of the failure time was of 11.7 hours.

Step-by-step explanation:

Sample mean:

Sum of all values divided by the number of values. So

[tex]\overline{x} = \frac{34+40+46+49+61+64}{6} = 49[/tex]

The sample mean of failure time was of 49 hours.

Standard deviation:

Square root of the division between the sum of the differences squared betweene each value and the mean, divided by the sample size subtracted by 1. So

[tex]s = \sqrt{\frac{(34-49)^2+(40-49)^2+(46-49)^2+(49-49)^2+(61-49)^2+(64-49)^2}{5}} = 11.7[/tex]

The standard deviation of the failure time was of 11.7 hours.

Answer:

question 8

Step-by-step explanation:

y = 4

2x + 3y = 22

put y = 4 into equation 2

2x + 3 ( 4) = 22

2x + 12 = 22

2x = 22 - 12

2x = 10

x = 5

therefore x = 5 and y = 4

Answer:

Step-by-step explanation:

The iterator for Newton's method gives the next approximation (x') as ...

  x' = x -g(x)/g'(x) . . . . . where g'(x) is the derivative of g(x)

We have defined g(x) = x^3+x+3, the function we want the zero of. We have defined the iteration function to be f(x).

__

Additional comment

Modern graphing calculators not only make the iteration trivially simple, they also give a first approximation good to 2 or 3 decimal places in many cases.

Answer:

x = 3

Step-by-step explanation:

(-2 + 40x) + 62° = 180° (adjacent angles are supplementary)

-2 + 40x + 62 = 180

Add like terms

40x + 60 = 180

Subtract 60 from each side

40x + 60 - 60 = 180 - 60

40x = 120

Divide both sides by 40

40x/40 = 120/40

x = 3

Answer:

5^2 + h^2 = 10^2

Step-by-step explanation:

This is a clear example of the Pythagorean Theorem, a relation of all sides in a right triangle. The equation itself is a^2 + b^2 = c^2. By simply plugging in the given values into the triangle, you would get the answer.

Answer:

To determine the height we will use a² = b²+c²

(10m)²= (5m)²+(h)²

<=> 100m²=25m²+h²

<=> 100m²-25m²=75m²=h²

<=> √ 75m² = h = 8,660m

Answer:

  A.  17.5 miles

Step-by-step explanation:

Your knowledge of triangles tells you the hypotenuse is longer than the long leg of the triangle, and is shorter than than the sum of the two legs. This means the difference between Michael's distance and Leah's distance will be strictly less than 25 miles.

The only answer choice in that range is 17.5 miles.

__

If you want to do the math, you can find Michael's distance to be ...

  38 +25 = 63 miles.

Leah's distance will be ...

  √(38² +25²) = √2069 ≈ 45.5 miles.

Then Michael's excess distance is ...

  63 -45.5 = 17.5 miles

Answer:

  yes, yes, no; No

Step-by-step explanation:

We have to assume you have no trouble with single-digit addition and comparison of two numbers.

  3+4 > 1   ⇒   7 > 1 . . . . yes

  4+1 > 3   ⇒   5 > 3 . . . . yes

  3+1 > 4   ⇒   4 > 4 . . . . no

These lengths will not make a triangle because the triangle inequality is not satisfied.

Additional comment

You will notice that we found the result of interest when we added the two smallest numbers (1 and 3) and compared the sum to the largest number (4). This is a shortcut you can use for any "will these make a triangle" question. You don't need to bother comparing larger numbers to smaller ones. You already know they are larger.

Answer:

51

Step-by-step explanation:

The problem states "the Panthers won 40 games out of 17 games"

It is impossible to win more games than the number of games.

Perhaps the problem should state "the Panthers won 17 games out of 40 games"

If this is correct, then we can answer the question with a proportion.

17 wins is to 40 games as x wins is to 120 games

17/40 = x/120

40 * x = 17 * 120

Divide both sides by 40.

x = 17 * 3

x = 51

Step-by-step explanation:Its B because Hyperbolic geometry, also called Lobachevskian Geometry, a non-Euclidean geometry that rejects the validity of Euclid's fifth, the “parallel,” postulate. Simply stated, this Euclidean postulate is: through a point not on a given line there is exactly one line parallel to the given line.

Answer: x =8

Step-by-step explanation:

-12 + 9x = 60 (the other angles are 60, 180 - (60 + 60) = 60)

9x = 72

x = 8

Answer:

x = 8°

Step-by-step explanation:

We know that sum of interior angles of a triangle is 180°, therefore;

(Angle 1) + (Angle 2) + (Angle 3) = 180°

(60)° + (60)° + (-12 + 9x)° = 180°

120° + (-12 + 9x) = 180°

108° + 9x° = 180°

9x = 180 - 108

9x = 72°

x = 72/9

x = 8°

Therefore the value of x is 8°.

Answer:

h(-4) = 123

Step-by-step explanation:

h(x) = 8x² – 5

h(-4) = 8(-4)² - 5

h(-4) = 8(16) - 5

h(-4) = 128 - 5

h(-4) = 123

Answer:

Step-by-step explanation:

Answer:

y=6

Step-by-step explanation:

Let us start with the general equation of a line, y=mx+b. m represents the slope of the line, b represents the y intercept, and the y and x represents the values of the coordinate that the line passes through.

In this case, we know our line is parallel to y=-3, thus it has the same slope as it. Notice that in y=-3, there is no x. Therefore, the slope must be 0!

We now have equation:

[tex]y=0x+b[/tex]

Let us plug in the coordinate it passes through (2,6), to solve for b.

[tex]6=0*2+b\\6=b\\[/tex]

Now we have everything! Let us write the equation of the line now.

[tex]y=6[/tex]

I hope this helps! Let me know if you have any questions :)

Answer:

x = 170

Step-by-step explanation:

In order to solve this, we need to know that there is 360° in a full circle. Knowing this, we can make the following equation from the diagram provided...

60° + 130° + x° = 360

x° = 360° - 60° - 130°

x° = 170°

x = 170

Answer:

   yes

Step-by-step explanation:

The triangles are given as right triangles. Hypotenuses QT and RS are given as congruent.

We also have XS ≅ TP. By the addition property of equality, this means ...

  XS +ST ≅ ST +TP

By the segment sum theorem, this means ...

  XT ≅ SP

XT and SP are the corresponding legs of the right triangles. So, we have corresponding hypotenuses and corresponding legs congruent. This lets us conclude ΔXQT ≅ ΔPRS by the HL theorem.
