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

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

Mrs. Peterson makes ceramic figurines. She recently made 25 figurines. Of those figurines, 16 are animals. What percent of the figurines are NOT animals?
Answers
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%).

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
Given that tots amount is 72000. That is x + x + 9000 = 72000.
So x = CD = $31500
And bonds = 31500 + 9000 = $40500
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.
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.

Answers
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]

(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]

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

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.
