[tex]4(n - 3) + 2n = 12[/tex]

[tex]4n - 12 + 2n = 12[/tex]

[tex]6n - 12 = 12[/tex]

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.

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.

Answer:

f^-1 (x) = x/5

Step-by-step explanation:

f(x) = 5x

Replace f(x) with y

y= 5x

Exchange x and y

x = 5y

Solve for y

Divide each side by 5

x/5 = 5y/5

x/5 = y

The inverse is x/5

Complete Question:

A small jet can carry up to 41 passengers and 3 crew members. There is a weight restriction of 9200 pounds on board. The combined weight of each passenger (or crew member) and his luggage has a mean of 197.9 pounds, with a standard deviation of 64.1 pounds. What is the probability that the weight limit will be exceeded when there are exactly 41 passengers and 3 crew members on board? Carry your intermediate computations to at least four decimal places. Report your result to at least three decimal places.

Answer:

The probability that the weight limit will be exceeded when there are exactly 41 passengers and 3 crew members on board is;

0.253

Step-by-step explanation:

a) Data and Calculations:

Capacity of the small jet = 41 passengers and 3 crew members = 44

Weight restriction = 9,200 pounds

Mean of the combined weight of passengers and crew = 8,707.6 (44 * 197.9) pounds

Weight's standard deviation = 2,802.4 (44 * 64.1) pounds

Excessive weight total = 11,528 (8,707.6 + 2,802.4)

Excess weight = Excessive weight total minus Total Weight Restriction

=2,328 (11,528 - 9,200)

Probability of exceeding weight limit = Excess weight/Weight restriction

= 2,328/9,200

= 0.253

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

Answer:

25.625 litros de agua por familia.

No sobrará agua.

Step-by-step explanation:

En promedio el ser humano tiene que tomar al menos 3 litros de agua al día, con esto en mente y pensando que tienes 48 familias de las cuales en promedio serían 5 personas que conforman cada familia, tendrías que son en total:

48*5=240 personas

Tienes que tener almenos 3 litros de agua para cada persona:

240*3=720

Tienes en total 1230 litros de agua, sólo para cubrir lo que las personas necesitan tomar de agua son 720, falta ver si tienen que lavar, cocinar, limpiar o bañarse, entonces con los 1230 litros conseguidos, no alcanzaría ni para dos días de sólo tomar agua.

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.

Answer:

Depends on how many digits the question wants. If rounded, 38%. Or just 37%

Step-by-step explanation:

She made 25 in all.

16 of them are animal figures. The question is asking what percent is NOT animal figure, so we need to subtract 25 by 16. That gives us 9. To find the percent, we need to divide 9 by the whole, which is 24. 9/24=0.375

The answer is 37% or 37.5% (It depends on how many digits the question is asking for. Also try rounding (38%).

(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
