Answer:

[tex]f(6)=-21\\\\g(-3)=-52[/tex]

Step-by-step explanation:

When given the following two functions,

[tex]f(x) =-3x-3\\g(x)=2x^3+2[/tex]

One is asked to evaluate the functions for, (f(6)) and (g(-3)). One can do this by substituting the values (6) into the function (f) and (-3) into the function (g). These values will replace the parameter (x).

[tex]f(6)=-3(6)-3\\[/tex]

Simplify,

[tex]f(6)=-18-3\\f(6)=-21[/tex]

Now repeat this process for the guncion (g(x)) to evaluate for (g(-3))

[tex]g(-3)=2(-3)^3+2[/tex]

Simplify,

[tex]g(-3)=2(-27)+2\\g(-3)=-54+2\\g(-3)=-52[/tex]

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:

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.

Step-by-step explanation:

Answer: [tex]\frac{363}{14} [/tex] square inches

Step-by-step explanation:

Surface area of cone = [tex]\pi r( l +r)[/tex], where r= radius of the base of cone, l= diagonal length from the base to the tip

As per given,

Diameter = 3 inches

radius(r) = [tex]\frac32[/tex] inches

l = 4 inches

Surface area = [tex]\frac{22}{7} (\frac32)(4+\frac32)[/tex]

= [tex]\frac{22}{7} (\frac32)(\frac{11}2)[/tex]

= [tex]\frac{363}{14} [/tex] square inches

Required surface area of cone = [tex]\frac{363}{14} [/tex] square inches

Answer:

6

Step-by-step explanation:

We need to find the slope

We have 2 points

(0,0) and (1,6)

m = (y2-y1)/(x2-x1)

   = (6-0)/(1-0)

   = 6/1

  = 6

y = 6x

The constant of proportionality is 6

Answer:

The constant of proportionality is 6.

Step-by-step explanation:

(0,0) and (1,6)

m = (y2-y1)/(x2-x1)

→ (6-0)/(1-0)

→ 6/1

So, y = 6x.

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.

Step-by-step explanation:

put the value of x in the given function...

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

Statistical significance

Step-by-step explanation:

The Statistical significance provides a link between the  dependent and the independent variable. It provides us the indication that the change in the independent variable is correleated with the shift caused in the dependent variable.

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: 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°.

Hope this helps!

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

C. It can make decision making more efficient.

Step-by-step explanation:

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.
