Answer:

45

Step-by-step explanation:

Let the three quantities be x, y and z.

\because \: average =  \frac{sum \: of \: quantities}{no \: of \: quantities}  \\  \\  \therefore \: 15 =  \frac{x + y + z}{3}  \\  \\ 15 \times 3 = x + y + z \\  \\ \huge \purple{ 45 = x + y + z}

Fill in the blanks to complete the following statements. Bold left parenthesis a right parenthesis For the shape of the distribu
Nana76 [90]

Answer:

For the shape of the distribution of the sample proportion to be approximately​ normal, it is required that ​np (1 -p ) greater than or equals 10.

Suppose the proportion of a population that has a certain characteristic is 0.35. The mean of the sampling distribution of ModifyingAbove p with caret from this population is mu Subscript ModifyingAbove p with caretequals​0.35.

Step-by-step explanation:

Normal distribution is the shape data takes as a symmetrical bell shaped curve. Normal approximation can only be taken when np or np(1-p) greater than 10.

Fill in the blanks to complete the following statements:

  • For the shape of the distribution of the sample proportion to be approximately​ normal, it is required that ​np(1 - p)greater than or equals​__10____.
  • Suppose the proportion of a population that has a certain characteristic is 0.35. The mean of the sampling distribution of ModifyingAbove p with caret from this population is mu Subscript ModifyingAbove p with caretequals​__0.35____.

The equation of the graph y= x^{3}-2x^{2} +3x-4 has no symmetry

The equation of the graph y = x^{3}-2x^{2} +3x-4

Replace y with -y in the given equation

-y = x^{3}-2x^{2} +3x-4

When replacing y with -y gives the different equation. The equation is not symmetric with respect to x axis

Replace x with -x in the given equation

y = (-x)^{3} -2(-x^{2} )-3(-x)-4

y = -x^{3}-2x^{2} +3x-4

When replacing x with -x gives the different equation. The equation is not symmetric with respect to y axis

Replace x with -x and y with -y in the equation

-y = (-x)^{3} -2(-x^{2} )-3(-x)-4

-y =  -x^{3}-2x^{2} +3x-4

When replacing x with -x and y with -y gives the different equation. The equation is not symmetry with respect to origin.

Hence, the equation of the graph y= x^{3}-2x^{2} +3x-4 has no symmetry
