Answer:
D. 39
Step-by-step explanation:
1. Anytime you see x, replace it with 3: [tex]3^3+3^2+3[/tex]
2. You can plug this into a calculator or do it manually. [tex]3^3=27, 3^2=9\\[/tex]
3. Now add it all together: 27+9+3=39.
4. D is the answer
Answer:
d) 39
Step-by-step explanation:
Given that,
→ x = 3
Let's solve the problem,
→ x³ + x² + x
→ (3)³ + (3)² + 3
→ 27 + 9 + 3
→ 39 {option d}
Hence, the solution is 39.

Question 36 Choose the expression that is the largest value. cos 30° O tan 30° sin 45 tan 45°
Answer:
Step-by-step explanation:
Remark
The moment you put Tan(45) in the choices, non of the other choices can compete.
Tan(45) = 1
Sin(a) or cos(a) are all less then one except when a = 0 or 90. Even then they can only have a value of 1. Since none of the angles = 0 or 90 then the largest value is Tan(45) = 1.
jason needs an 75% average in his writing class to pass. on his first 4 exams, he earned scores of 68%,72%,85% and 90% what is the minimum score Jason can earn on his fifth and final test to pass??
Answer:
71%
Step-by-step explanation:
Here´s how I do average scores
68 to 90
the difference in the numbers is =
90 - 68 (just a tip, subtract the highest number from the lowest number) =
22/2 will give you 11 and the reason I do this is to compare all the other numbers
11 + 68 or 90 - 11 =
79
72 to 85
85 - 72
13/2 = 6.5
72 + 6.5 or 85 - 6.5
78.5
since grades are rounded to the nearest tenth
79 - 79
79%
so he needs a 75% average to pass
79 - 75 = 4
75 - 4 = 71
The minimum score is 71%

Zoe supplies costumes to a number of theatre companies. She recently provided 20 different hats, including 4 fedoras. Considering this data, how many of the next 15 hats requested from Zoe’s inventory will be fedoras?
Answer:
3.
Step-by-step explanation:
If there were 20 hats, and 4 of them were fedoras, we can conclude that 1/5 of the sent hats are going to be fedoras.
If there are 15 hats, we multiply 15 by 1/5 to get 3.

What is an equation?An equation is an expression that shows the relationship between two or more variables and numbers.
The magnitude, m, of an earthquake is:
m = log (I/S)
Where I is the intensity of the earthquake and S is the intensity of a "standard" earthquake. Hence, for an earthquake that is 35 times more intense than a standard earthquake:
m = log (35S / S) = log (35) = 1.5

What is the equation of this line in standard form?
Based on the calculations, the equation of this line in standard form is equal to 6x - 11y = 13.
Given the following data:
Points on x-axis = (1 1/2, -4) = (1.5, -4).Points on y-axis = (2, -1).How to calculate an equation of a line?Mathematically, the equation of a line in standard form is given by this formula:
y - y₁ = m(x - x₁)
Where:
m is the slope.y is the point on the horizontal axis.x is the point on the vertical axis.Next, we would determine the slope of this line:
[tex]Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}\\\\Slope = \frac{-1\;-\;2}{-4\;-\;1.5}\\\\Slope = \frac{-3}{-5.5}[/tex]
Slope = 6/11.
For the equation of this line, we have:
y - 2) = 6/11(x - 3/2)
y - 2 = 6x/11 - 9/11
11y - 22 = 6x - 9
6x - 11y = -9 + 22
6x - 11y = 13.

What is the area of the arrow?
Answer:
C. 192 1/2 in^2.
Step-by-step explanation:
Split this up anto 1 triangle and one rectangle
Area of the triangle = 1/2 * base * height
Its height = 36 - 25 = 11, and the base = 2 1/4 + 2 1/4 + 5 1/2= 10.
So it's area = 1/2 * 10 * 11 = 55.
Area of rectangle = 25 * 5 1/2 = 137 1/2.
Total area of the arrow = 55 + 137 1/2 = 192 1/2 in^2.

Use for questions 21-24: Out of 50 students, 24 are taking art and 30 are taking music. Sixteen of the
students are taking both art and music. If two different students from this group are chosen at
random, find each probability.
21. Both students take art
22. Both students take both art and music.
23. Both students take music, but not art.
24. Neither students takes music.
Probability of each case given in the problem will be 0.3327, 0.1033, 0.0922, 0.3367 respectively.
What does probabilty of occurance of an event signifies?The probability of an occurrence is an indicator of its likelihood. It is most frequently described as a number between 0 and 1, where 0 indicates an impossibility and 1 indicates assurance.
If an event has a higher probability, it is more likely to happen. One can use various mathematical methods or, depending on the situation, divide the number of favourable possibilities by the total number of potential outcomes to calculate the likelihood of an event.
Now for given cases in the problem,
21. Chances that both pupils will enrol in art: divided by the total number of ways there are to select two students from the full group of 50 students, the number of ways to select two students from the 24 art students is equal to= [tex]^{24}C_2 / ^{50}C_2=(\frac{24!}{22!.2!})/(\frac{50!}{48!.2!} )= \frac{24*23}{2} /\frac{50*49}{2} =0.3327[/tex]
22. Chance that both pupils would study music and art: the number of options there are to select two students from the 16 students who are studying both art and music divided by the total number of methods there are to select two students from the 50 students.= [tex]^{16}C_2 / ^{50}C_2=(\frac{16!}{14!.2!})/(\frac{50!}{48!.2!} )=\frac{16*15}{2} /\frac{50*49}{2} =0.1033[/tex]
23. Probability that both students take music but not art is calculated by dividing the total number of possibilities there are to select two students from the 50 students by the number of students in the group of 14 who only take music= [tex]^{14}C_2 / ^{50}C_2=(\frac{14!}{12!.2!})/(\frac{50!}{48!.2!} )= \frac{14*13}{2} /\frac{50*49}{2} =0.0922[/tex]
24. The likelihood that neither student studies music is determined by the number of ways there are to select two students from the 26 students who do not study music divided by the total number of ways there are to select two students from the complete group of 50 students. = [tex]^{26}C_2 / ^{50}C_2= (\frac{26!}{24!.2!})/(\frac{50!}{48!.2!})=\frac{26*25}{2} /\frac{50*49}{2} = 0.3367[/tex]
