Answer:

10 two-pointers, 6 three-pointers

Step-by-step explanation:

10 two-pointers, 6 three-pointers

10 shots * 2 points = 20 points

6 shots * 3 points = 18 points

20 + 18 = 38 points

Answer:

a

             [tex]P(K = k ) = \  ^nC_x * p^k  *  (1-p)^{n-k}[/tex]

Here  k is the random number of number of pairs of shoes that will be returned for refund, which can be  k = 0,1 ,2,3,4 ..., 120

b

The mean is   [tex]E(K) =  np =  13.2[/tex]  

The  standard deviation is  [tex]\sigma =  3.43[/tex]

c

The mean is  [tex]E(C) =   E(105 K) =  1386[/tex]

The standard deviation is   [tex]\sigma  =  381.48 [/tex]  

Step-by-step explanation:

From the question we are told that

   The  cost to dealer for each refund is  [tex]C =  \$105[/tex]

   The  probability  that a shoe will refunded is  [tex]P(x) =  0.11[/tex]

   The number of shoes purchased is  n  =  120 pairs

Generally the probability distribution of the number of pairs of shoes that will be returned for refunds is

          [tex]P(K = k ) = \  ^nC_x * p^k  *  (1-p)^{n-k}[/tex]

Here  k is the random number of number of pairs of shoes that will be returned for refund, which can be  k = 0,1 ,2,3,4 ..., 120

Generally the mean is mathematically represented as

     [tex]E(K) =  np =  120 * 0.11[/tex]

=>    [tex]E(K) =  np =  13.2[/tex]  

Generally the  standard deviation is mathematically represented as

     [tex]\sigma  =  \sqrt{ n*  p  (1-p)}[/tex]

=>    [tex]\sigma  =  \sqrt{ 120* 0.11  (1-0.11)}[/tex]

=>    [tex]\sigma =  3.43[/tex]

Generally the total refund cost is mathematically represented as

     [tex]C =  105 K[/tex]

Here K denotes the number of shoes returned

Generally the mean of the total refund cost is mathematically represented as

           [tex]E(C) =   E(105 K) =  105 E(K)[/tex]

=>         [tex]E(C) =   E(105 K) =  105 * 13.2[/tex]

=>         [tex]E(C) =   E(105 K) =  1386[/tex]

Generally the variance of the total refund cost is mathematically represented as

       [tex]Var(K) =  105^2 *  E(K)[/tex]

=>     [tex]Var(K) =  105^2 *  13.2[/tex]

=>    [tex]Var(K) =  145530[/tex]  

=>      [tex]\sigma =  \sqrt{145530 }[/tex]

=>    [tex]\sigma  =  381.48 [/tex]  

Answer:

$13.95

Step-by-step explanation:

$166.29 ×12/100

=$13.95 will be the tip.

Answer:

$13.95

Step-by-step explanation:

Convert the 12% to an actual number that can be used in a calculator. For percents, this is done by dividing the percent (in this case 12%) by 100%.So, the conversational term "12%" becomes 12% / 100% = 0.12 in terms of a real mathematical number. Then you need to find out what 12% of your $116.29 meal cost is.This is always done by multiplying 0.12 by $116.29, or 0.12 x $116.29=$13.95.

Answer:

Step-by-step explanation:

To show that the equations are the same, we need to rewrite one of the equations as an equivalent equation of the second

Damita's claim is true

The equations are given as:

0.8x - 0.8 = 1.6

4/5 ( x - 1 ) = 1 (3/5)

We need to rewrite one of the equations, as follows:

4/5 ( x - 1 ) = 1 (3/5)

Express as decimal

0.8 ( x - 1 ) = 1 + 0.6

Open the brackets

0.8x - 0.8 = 1.6

Now we have:

0.8x - 0.8 = 1.6 (the first equation) and 0.8x - 0.8 = 1.6 (the equivalent of the second equation)

The above shows that both equations are the same

Step (1)

We know that the sum of all the terms in an infinite geometric sequence finding from following equation whenever |q| < 1 .

q = magnitude

[tex]s( \infty ) = \frac{t(1)}{1 - q} \\ [/tex]

So :

[tex]s( \infty ) = \frac{t(1)}{1 - q} \\ [/tex]

[tex]81 = \frac{t(1)}{1 - q} \\ [/tex]

[tex]81(1 - q) = t(1)[/tex]

Remember it I'll use it again.

_________________________________

Step (2)

We know that the sum of the n first terms of a geometric sequence finding from following equation.

[tex]s(n) = \frac{t(1) \times (1 - {q})^{n} }{1 - q} \\ [/tex]

_________________________________

Sum of all terms starting from the third is 9.

So :

[tex]s(2) + s(3 - \infty ) = 81[/tex]

[tex]s(2) + 9 = 81[/tex]

Sides minus 9

[tex]s(2) = 81 - 9[/tex]

[tex]s(2) = 72[/tex]

So :

[tex]t(1) + t(2) = 72[/tex]

[tex]t(1) + t(1) \times q = 72[/tex]

Factoring t(1)

[tex]t(1) \times (1 + q) = 72[/tex]

We have found t(1) = 81 ( 1 - q ) in step (1).

So :

[tex]81(1 - q)(1 + q) = 72[/tex]

Divided sides by 81

[tex](1 - q)(1 + q) = \frac{72}{81} \\ [/tex]

[tex](1 - q)( 1 + q) = \frac{8}{9} \\ [/tex]

[tex]1 - {q}^{2} = \frac{8}{9} \\ [/tex]

Subtract sides minus -1

[tex] - {q}^{2} = \frac{8}{9} - 1 \\ [/tex]

[tex] - {q}^{2} = \frac{8}{9} - \frac{9}{9} \\ [/tex]

[tex] - {q}^{2} = - \frac{1}{9} \\ [/tex]

Negatives simplifies

[tex] {q}^{2} = \frac{1}{9} \\ [/tex]

Radical sides

[tex]q = + \frac{1}{3} \\ q = - \frac{1}{3} [/tex]

_________________________________

Step (4)

If q = 1/3 :

[tex]81(1 - q) = t(1)[/tex]

[tex]81(1 - \frac{1}{3}) = t(1) \\ [/tex]

[tex]81( \frac{2}{3}) = t(1) \\ [/tex]

[tex]t(1) = 27 \times 2[/tex]

[tex]t(1) = 54[/tex]

So :

[tex]t(2) = t(1) \times q[/tex]

[tex]t(2) = 54 \times \frac{1}{3} \\ [/tex]

[tex]t(2) = 18[/tex]

°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°

If q = - 1/3 :

[tex]81(1 - q) = t(1)[/tex]

[tex]81(1 - ( - \frac{1}{3})) = t(1) \\ [/tex]

[tex]81(1 + \frac{1}{3}) = t(1) \\ [/tex]

[tex]81( \frac{4}{3}) = t(1) \\ [/tex]

[tex]t(1) = 27 \times 4[/tex]

[tex]t(1) = 108[/tex]

So :

[tex]t(2) = t(1) \times q[/tex]

[tex]t(2) = 108 \times - \frac{1}{3} \\ [/tex]

[tex]t(2) = - 36[/tex]

Answer:      2.381875 is the answer.

Answer:

Answer:

y(x) = c_1 e^(-1/(2 x^2))

Step-by-step explanation:

Solve the separable equation x^3 (dy(x))/(dx) - y(x) = 0:

Solve for (dy(x))/(dx):

(dy(x))/(dx) = y(x)/x^3

Divide both sides by y(x):

((dy(x))/(dx))/y(x) = 1/x^3

Integrate both sides with respect to x:

integral((dy(x))/(dx))/y(x) dx = integral1/x^3 dx

Evaluate the integrals:

log(y(x)) = -1/(2 x^2) + c_1, where c_1 is an arbitrary constant.

Solve for y(x):

y(x) = e^(-1/(2 x^2) + c_1)

Simplify the arbitrary constants:

Answer:  y(x) = c_1 e^(-1/(2 x^2))

Step-by-step explanation:

y = mx + b

the one being multiplied  to x is the slope

Answer:

slope: -12

y-intercept: 7

Step-by-step explanation:

The slope-intercept form of the equation of a line is

y = mx + b

where m = slope, and b = y-intercept.

Your equation is

y = -12x + 7

Your equation is already in the slope-intercept form.

m = -12

b = 7

slope: -12

y-intercept: 7

Step-by-step explanation:

use -4y for x in the second equation

-4 y + 5 y = 2

so

y = 2

then x = -4(2) = -8

(-8 , 2)

990 = 1000 - 10

so 3 x 990 = 3 x (1000 - 10) = 3 x 1000 + 3 x (-10) = 3000 - 30 = 2970

and

990 = 900 + 90

so 3 x 990 = 3 x (900 + 90) = 3 x 900 + 3 x 90 = 2700 + 270 = 2970

Answer:

The critical value  is  [tex]t_{\frac{0.10}{2} , 14 } =[ - 1.761,1.761][/tex]

Step-by-step explanation:

From the question we are told that

   The sample size is  n =  15

   The  level of significance is  [tex]\alpha = 0.10[/tex]

The null hypothesis is  [tex]H_o : \mu _1 = \mu_2[/tex]

The alternative hypothesis is  [tex]H_a : \mu_1 \ne \mu_2[/tex]

Here [tex]\mu_1[/tex] is average time for previous year

        [tex]\mu_2[/tex] is the average time for current year

Generally the degree of freedom is mathematically represented as

         [tex]df = n -1[/tex]

=>      [tex]df = 15 - 1[/tex]

=>     [tex]df = 14[/tex]

Generally from the student  t distribution table the critical value  for [tex]\frac{\alpha }{2}[/tex] at a degree of freedom of  [tex]df = 14[/tex] for a two tailed test  is  

      [tex]t_{\frac{0.10}{2} , 14 } =[ - 1.761,1.761][/tex]

Answer:

3rd option

Step-by-step explanation:

to find the x- intercept let y = 0 in the equation and solve for x

2x - 3(0) = - 12

2x  - 0 = - 12

2x = - 12 ( divide both sides by 2 )

x = - 6 ← x- intercept

To find the y- intercept let x = 0 in the equation and solve for y

2(0) - 3y = - 12

0 - 3y = - 12

- 3y = - 12 ( divide both sides by - 3 )

y = 4 ← y- intercept

The graph of both plots would be the one graph in option C.

Combined area = 2(area of one rectangular plot) = 720 sq. yds.

Area of a rectangular shape = length × width

From the graph given, 1 unit represents 20 yards. Therefore:

Therefore, the graph of both plots would be the one given in option C.

The plot is rectangular in shape having 60 yards × 60 yards. Therefore:

Area of 1 plot = length × width = 60 × 60 = 360 square yards.

Combined area = 2(area of one rectangular plot) = 2(360) = 720 sq. yds.
