So, the graph of this equation 4 ≤ x is given as shown below.
Stan guessed on all 10 questions of a multiple-choice quiz. Each question has 4 answer choices. What is the probability that he got at least 2 questions correct? Round the answer to the nearest thousandth.
The probability that he got at least 2 questions correct is 0.756
Lets assume, the event of getting a question correct is P
As, each question has 4 answer choices and only one choice is correct,
So, P = [tex] \frac{1}{4} [/tex]
When
the probability of getting 1 success in 1 trial is p, then the probability of getting exactly x successes out of n trials is given by the
formula :
(ⁿCₓ )(P)ˣ (1-P)ⁿ⁻ˣ
Here the total number of questions is 10. So, n= 10
Stan needs to get at least 2 questions correct, that means he can get 2, 3, 4, 5, 6, 7, 8, 9 or 10 questions correct.
Now according to the formula,
P(x=2) = ¹⁰C₂ ([tex] \frac{1}{4} [/tex])² ([tex] 1- \frac{1}{4} [/tex])¹⁰⁻²
= ¹⁰C₂ [tex] (\frac{1}{16})(\frac{3}{4})^8 [/tex]
= 0.281567573
P(x=3) = ¹⁰C₃ ([tex] \frac{1}{4} [/tex])³ [tex] (\frac{3}{4})^7 [/tex]
= (120) ([tex] \frac{1}{4} [/tex])³ [tex] (\frac{3}{4})^7 [/tex]
= 0.250282287
P(x=4) = ¹⁰C₄ ([tex] \frac{1}{4} [/tex])⁴ [tex] (\frac{3}{4})^6 [/tex]
= (210)([tex] \frac{1}{4} [/tex])⁴ [tex] (\frac{3}{4})^6 [/tex]
= 0.145998001
P(x=5) = ¹⁰C₅ ([tex] \frac{1}{4} [/tex])⁵ [tex] (\frac{3}{4})^5 [/tex]
= (252) ([tex] \frac{1}{4} [/tex])⁵ [tex] (\frac{3}{4})^5 [/tex]
= 0.058399200
P(x=6) = ¹⁰C₆ ([tex] \frac{1}{4} [/tex])⁶ [tex] (\frac{3}{4})^4 [/tex]
= (210) ([tex] \frac{1}{4} [/tex])⁶ [tex] (\frac{3}{4})^4 [/tex]
= 0.016222000
P(x=7) = ¹⁰C₇ ([tex] \frac{1}{4} [/tex])⁷ [tex] (\frac{3}{4})^3 [/tex]
= (120) ([tex] \frac{1}{4} [/tex])⁷ [tex] (\frac{3}{4})^3 [/tex]
= 0.003089904
P(x=8) = ¹⁰C₈ ([tex] \frac{1}{4} [/tex])⁸ [tex] (\frac{3}{4})^2 [/tex]
= (45) ([tex] \frac{1}{4} [/tex])⁸ [tex] (\frac{3}{4})^2 [/tex]
= 0.000386238
P(x=9) = ¹⁰C₉ ([tex] \frac{1}{4} [/tex])⁹ [tex] (\frac{3}{4})^1 [/tex]
= (10) ([tex] \frac{1}{4} [/tex])⁹ [tex] (\frac{3}{4})^1 [/tex]
= 0.000028610
P(x=10) = ¹⁰C₁₀ ([tex] \frac{1}{4} [/tex])¹⁰
= 0.000000953
Now we will just add all the probabilities and get:
0.281567573 + 0.250282287+ 0.145998001+ 0.058399200+ 0.016222000+0.003089904+0.000386238+ 0.000028610 +0.000000953
= 0.755974766
= 0.756 (rounding to the nearest thousandth)
So, the probability that he got at least 2 questions correct is 0.756

fitness center currently has 320 members. Monthly membership fees are $45. The manager of the fitness center has determined that each time the membership fees increase by $5, approximately 10 members leave and go to a different gym.
Write an equation that can be used to find the revenue of the fitness center in dollars, y, after x price increases of $5.
y = -50x2 + 1,150x + 14,400
y = -50x2 + 3,425x + 14,400
y = -50x2 + 2,975x + 14,400
y = -50x2 + 2,050x + 14,400
Answer:
y= -50x^2+1,150x+14,400
Step-by-step explanation:
fitness center currently has 320 members. Monthly membership fees are $45. The manager of the fitness center has determined that each time the membership fees increase by $5, approximately 10 members leave and go to a different gym.
LEt x be the number of price increases of $5
y is the revenue
Revenue= membership fee * members
for x number of increase in fee by 5 then member ship fee becomes 45+5x
approximately 10 members leave, so members becomes (320-10x)
y = (45+5x) (320-10x)
Multiply it using FOIL method
y=45 * 320 +45*(-10x) + 5x * 320 + 5x * (-10x)
y=14400 - 450x + 1600x - 50x^2
Combine like terms
y= -50x^2+1150x+14400

A shop sells three types of boots (football, rugby and hiking). Sales are usually in the ratio 6 : 2 : 3 last month, 24 pairs of football boots were sold. How many boots altogether were sold last month?
Answer:
Total number of boots sold = 44
Step-by-step explanation:
Ratio of football, rugby and hiking boots sold = 6 : 2 : 3
24 pairs of football boots were sold.
That is
6 n = 24
n = 4.
Number of rugby boots sold = 2 n = 2 x 4 = 8
Number of hiking boots sold = 3 n = 3 x 4 = 12
Total number of boots sold = 6n + 2n + 3n = 11n = 11 x 4 = 44
Total number of boots sold = 44

452.16 m 2 = (3.14)(6 m)(x) + (3.14)(36 m 2)
452.16 m 2 = (18.84 m)x + 113.04 m 2
339.12 m 2 = (18.84 m)x
18 m = x
Answer:
Option D. 9 cm
Step-by-step explanation:
Surface area of the given figure is S = 243 cm² and we have to find the slant height.
We can see this figure comprises of 1 square and 4 triangles.
Let the slant height of the given triangles is L.
So area of one triangle = [tex]\frac{1}{2}(Slant height).(Base)[/tex]
and the area of square = side² = 9² = 81 cm²
Now surface area of total figure = Area of square + 4×(area of a triangle)
[tex]243=9^{2}+\frac{4}{2}(9.L)[/tex]
243 = 81 + 2×9L
18L = 243 - 81 = 162
[tex]L=\frac{162}{18}[/tex]
L = 9 cm
Therefore Option D. 9 cm is the correct answer.

The temperature on Saturday was 6 1/2 °C. On Sunday, it became 3 3/4 °C colder. What was the temperature on Sunday?
Answer:
The temperature on Sunday was 2.75 degrees Celsius.
Step-by-step explanation:
The temperature on Saturday was = [tex]6\frac{1}{2}[/tex] or 6.5 degree Celsius
The temperature on Sunday became [tex]3\frac{3}{4}[/tex] or 3.75 degrees colder.
When the temperature falls of it gets colder, this means the new temperature is less than the previous one. The lower the temperature, the more colder it is.
So, in the question, the temperature gets colder by 3.75 degrees, so the temperature must have been = 6.5-3.75 = 2.75 or [tex]2\frac{3}{4}[/tex] degrees Celsius.
Therefore, the temperature on Sunday was 2.75 degrees Celsius.

Which of the binomials below is a factor of this trinomial?
3x2 + 18x + 24
A. x + 4
B. x - 4
C. x - 3
D. x + 3
Final answer:
The binomial factor of the trinomial 3x^2 + 18x + 24 is 'x + 4', which corresponds to Option A.
Explanation:
The student is asking which binomial is a factor of the trinomial 3x2 + 18x + 24. To find a factor, you can either factor the trinomial directly or use the zero product property, which states that if a product equals zero, then at least one of the factors must be zero. Since we're looking for a binomial factor and not solving for x, we'll factor the trinomial.
Factors of 3x2 are 3x and x, and factors of 24 that add up to 18 (when multiplied by 3 or 1 from the 3x2 term) are 6 and 4. Thus, the trinomial can be factored as (3x + 4)(x + 6). So, the binomial that is a factor of the trinomial is x + 4, which is Option A.
