Step-by-step explanation:
f(x) = 2x3 + 3x2 – 7x + 2
g(x) = 2x – 5
Find (f + g)(x).
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?
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 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.
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.

El profesor Ricardo consiguió para una comunidad de 48 familia un tanquero con 800 litros con agua y otro tanquero con 430 litro con agua ¿cuantos litros de agua cada familia ?¿crees que sobre agua ?
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.

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 news program wishes to test whether there is evidence that more than three-quarters of U.S. adults are opposed to the verdict. Five hundred and sixty-two partici- pants participated in the survey, of which 82% said that they were unhappy with the verdict. a. State the null and alternative hypotheses for this test. b. What is the value of the statistic
Answer:
A)Null Hypothesis; H0: p ≤ 0.75
Alternative Hypothesis; Ha: p > 0.75
B) Test statistic is z = 3.83
Step-by-step explanation:
We are told the news program wants to test whether there is evidence that more than three - quarters of U.S. adults are opposed to the verdict.
Thus, p = 3/4 = 0.75
Thus,the hypothesis is;
Null Hypothesis; H0: p ≤ 0.75
Alternative Hypothesis; Ha: p > 0.75
Also, from a sample of Five hundred and sixty - two participants that participated in the survey, 82% said that they were unhappy with the verdict.
Thus; p^ = 82% = 0.82 and n = 562
Population standard deviation is given by the formula;
σ_p = √(p(1 - p)/n)
σ_p = √(0.75(1 - 0.75)/562)
σ_p = 0.0183
Now, the formula for the test statistic is;
z = (p^ - p)/σ_p
z = (0.82 - 0.75)/0.0183
z = 3.83

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.
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
