Answer 1

Answer:

#20 = 13

#21 = 1

#22 = -3

Step-by-step explanation:

Replace all of the x values in the equations for the one in the table.

Then solve.

This is the equation

Y= -4x - 3

A. x = -4

Replace x with -4.

   Y = -4 (-4) - 3

Solve.

   Y = 16 - 3

   Y = 13

#20 = 13

B. x = -1

Replace x with -1

   Y = -4 (-1) - 3

Solve.

   Y = 4 - 3

   Y = 1

#21 = 1

C. x = 0

Replace x with 0.

   Y = -4 (0) - 3

Solve.

   Y = 0 - 3

   Y = -3

#22 = -3

A flower vase has a volume of 1480 cubic centimeters (cm3). Use the fact
that 1 inch is equal to 2.54 cm to convert this volume to cubic inches (in).
Round your answer to the nearest tenth. Do not type the units in the space
below.

Answers

Answer:

The volume of the flower vase is 90.3 cubic inches.

Step-by-step explanation:

Dimensionally speaking, volume [tex][V][/tex] is equivalent to the product of length [tex][L][/tex], length [tex][L][/tex] and length [tex][L][/tex]. That is:

[tex][V] =[L]\times [L]\times [L][/tex]

In this case, an inch equals 2.54 centimeters and we proceed to convert the given volume of the flower vase as follows:

[tex]V = 1480\,cm^{3}\times \frac{1\,in\times 1\,in\times 1\,in}{2.54\,cm\times 2.54\,cm\times 2.54\,cm}[/tex]

[tex]V = 90.3\,in^{3}[/tex]

The volume of the flower vase is 90.3 cubic inches.

What percent of 16 is 50% of 50% of 48?

Answers

Answer:

150

Step-by-step explanation:

x %* 16 = 50% * 48

[tex]\frac{x}{100} = \frac{0.5 *48}{16} = \frac{24}{16} = \frac{6}{4} = \frac{3}{2} \\x = \frac{300}{2} = 150\\[/tex]

I guessed 50% is typed wrongly twice so I solved once with 50%

75% of 16 is equal to 50% of 50% of 48.

Percentage of 16 equivalent to 50% of 50% of 48 to be evaluate.

What are percentage?

Percentage is the matter of composition per unit whole composition.

Let x% of 16 = 50% of 50% of 48
x/100 *16 = 1/2*1/2*48
x/100*16 = 12
x = 12/16 * 100
x = 75%

Thus, 75% of 16 is equal to 50% of 50% of 48.

f(x) = 2x3 + 3x2 – 7x + 2
g(x) = 2x – 5
Find (f + g)(x).

Answers

Answer:

(f + g)(x) = 2x³ + 3x² - 5x - 3 ⇒ B

Step-by-step explanation:

Let us solve the question

∵ f(x) = 2x³ + 3x² -7x + 2

∵ g(x) = 2x - 5

→ (f + g)(x) means add f(x) and g(x)

∴ (f + g)(x) = (2x³ + 3x² - 7x + 2) + (2x - 5)

→ Add the like terms

∵ (f + g)(x) = 2x³ + 3x² + (-7x + 2x) + (2 - 5)

∴ (f + g)(x) = 2x³ + 3x³ + (-5x) + (-3)

→ Remember that (+)(-) = (-)

∵ 2x³ + 3x³ + (-5x) + (-3) = 2x³ + 3x² - 5x - 3

(f + g)(x) = 2x³ + 3x² - 5x - 3

A total of $72,000 is to be invested, some in bonds and some in certificates of deposit (CDs). If the amount invested in bonds is to exceed that in CDs by $9,000, how much will be invested
in each type of investment?

Answers

Let amount in Cd be x dollars. So amount in bonds would be x + 9000.
Given that tots amount is 72000. That is x + x + 9000 = 72000.
So x = CD = $31500
And bonds = 31500 + 9000 = $40500

Complete Question

Given a standard normal distribution, find the area under the curve that lies

(a) to the left of z = −1.39;

(b) to the right of z = 1.96;

(c) between z = −2.16 and z = −0.65;

(d) to the left of z = 1.43;

(e) to the right of z = −0.89;

(f) between z = −0.48 and z = 1.74.

Answer:

a

  [tex]P(Z < -1.39) = 0.082264[/tex]

b

 [tex]P(Z > 1.96) = 0.025[/tex]

c

 [tex]P(-2.16 < Z < -0.65 ) =0.2457[/tex]

d

 [tex]P(Z < 1.43) = 0.92364[/tex]

e

  [tex]P(Z > -0.48) = 0.68439[/tex]

f

  [tex]P(-0.48 < Z < 1.74 ) =0.6435[/tex]

Step-by-step explanation:

Considering a

From the question we are told that

   The  z-score is  z =  -1.39

Generally from the z table the  area under the curve that lies to the left of  z =  -1.39 is  

     [tex]P(Z < -1.39) = 0.082264[/tex]

Considering b

From the question we are told that

   The  z-score is  z = 1.96

Generally from the z table the  area under the curve that lies to the right of  z = 1.96 is  

     [tex]P(Z > 1.96) = 0.025[/tex]

Considering c

From the question we are told that

   The z-score is  z = −2.16 and z = −0.65

Generally from the z table the  area under the curve that lies between z = −2.16 and z = −0.65;

   [tex]P(-2.16 < Z < -0.65 ) = P(Z < -0.64 ) - P( Z < -2.16)[/tex]

From the z table the area under  (Z <  -0.64 )   and  ( Z <  -2.16) is  

      [tex]P(Z < -0.64 ) = 0.26109[/tex]

and

      [tex]P( Z < -2.16) = 0.015386[/tex]

So

     [tex]P(-2.16 < Z < -0.65 ) =0.26109- 0.015386[/tex]

=>  [tex]P(-2.16 < Z < -0.65 ) =0.2457[/tex]

Considering d

From the question we are told that

   The  z-score is  z = 1.45

Generally from the z table the  area under the curve that lies to the left of z = 1.43 is  

     [tex]P(Z < 1.43) = 0.92364[/tex]

Considering e

From the question we are told that

   The  z-score is  z = -0.48

Generally from the z table the  area under the curve that lies to the right of  z = 0.48 is  

     [tex]P(Z > -0.48) = 0.68439[/tex]

Considering f

From the question we are told that

   The z-score is  z = −0.48  and z = 1.74

Generally from the z table the  area under the curve that lies between z = −2.16 and z = −0.65;

   [tex]P(-0.48 < Z < 1.74 ) = P(Z < 1.74 ) - P( Z < -0.48)[/tex]

From the z table the area under  (Z <  1.74 )   and  ( Z <  -0.48) is  

      [tex]P(Z < 1.74 ) = 0.95907[/tex]

and

      [tex]P( Z < -0.48 ) = 0.31561[/tex]

So

     [tex]P(-0.48 < Z < 1.74 ) = 0.95907 - 0.31561[/tex]

=>  [tex]P(-0.48 < Z < 1.74 ) =0.6435[/tex]

The standard normal table shows the mathematical table which represent the value below a z-score in standard normal distribution. It is also known as z-table.

(a) The correct answer is 0.082264.

(b) The correct answer is 0.025

(c) The correct answer is 0.2457.

(d) The correct answer is 0.68439.

(e) The correct answer is 0.6435

Given:

(a)

The  z-score is  z =  -1.39

Refer the z-table area under the curve that lies to the left of [tex]z=-1.39[/tex],

[tex]P(Z<-1.39)=0.082264[/tex]

(b)

.The  z-score is  z = 1.96

Refer the z-table area under the curve that lies to the right of [tex]z=1.96[/tex],

[tex]P(Z>1.96)=0.025[/tex]

(c)

The  z-score is  [tex]z = -2.16[/tex] and [tex]z=-0.65[/tex]

Refer the z-table area under the curve that lies between [tex]z = -2.16[/tex] and [tex]z=-0.65[/tex],

[tex]P(-2.16<Z<-0.65)=P(Z<-0.64)-P(Z<-2.16)[/tex]

Thus,

[tex]P(Z<-0.64)=0.26109\\P(Z<-2.16)=0.015386\\P(-2.16<Z<-0.65)=0.26109-0.015386\\P(-2.16<Z<-0.65)=0.2457[/tex]

(d)

The  z-score is  [tex]z =1.45[/tex]

Refer the z-table area under the curve that lies to the right [tex]z = 1.45[/tex],

[tex]P(Z<1.45)=0.92364[/tex]

(e)

The  z-score is  [tex]z = -0.48[/tex]

Refer the z-table area under the curve that lies to the right [tex]z = -0.48[/tex],

[tex]P(Z>-0.48)=0.68439[/tex]

(f)

The z-score is  [tex]z =-0.48[/tex]  and [tex]z = 1.74[/tex]

Refer the z-table area under the curve that lies between [tex]z =-0.48[/tex]  and[tex]z = 1.74[/tex],

The z table the area under  [tex](Z < 1.74 )[/tex] is,

[tex]P(Z<1.74)=0.95907[/tex]

The z table the area under  [tex](Z < -0.48 )[/tex] is,

[tex]P(Z<-0.48)=0.31561[/tex]

Calculate the area under the curve that lies between [tex]z =-0.48[/tex]  and[tex]z = 1.74[/tex],

[tex]P(-0.48<Z<1.74)=P(Z<1.74)-P(Z<-0.48)\\P(-0.48<Z<1.74)=0.95907-0.31561\\P(-0.48<Z<1.74)=0.6435[/tex]

Thus,

(a) The correct answer is 0.082264.

(b) The correct answer is 0.025

(c) The correct answer is 0.2457.

(d) The correct answer is 0.68439.

(e) The correct answer is 0.6435
