Every evening for the months of September and October, the following eight Gry ndor students, Harry, Ron, Hermione, Ginny, Fred, George, Seamus, and Dean will play a game of Exploding Snap. Let's suppose that each night, exactly three of them play one game. Can there be a game of Exploding Snap every evening throughout September and October without having the same three Gry ndors play a game twice
Answer:
Yes. There can be 56 games (92%) of Exploding Snap every evening throughout September and October that can be played without having the same three Gry ndors play a game twice.
Step-by-step explanation:
This is a combination game without repetition.
The formula for combination without repetition is:
n! /r! (n - r)!
where n = 8 and r = 3
Therefore, n! /r! (n - r)!
= 8! / 3! (8 -3)!
= 40,320 / 6 (120)
= 40,320 / 720
= 56
There are 30 nights in September and 31 nights in October, totaling 61 nights
This implies that 56/61 games can be played in these two months without repeating the same three gamers.
56/61 = 0.918
= 92%
Order from least to greatest.

A bag contains 4 red marbles, 8 blue marbles and 2 green marbles. If two marbles are drawn out of the bag, what is the probability, to the nearest 10th of a percent, that both marbles drawn will be red?
Answer:
The probability, to the nearest 10th of a percent, that both marbles drawn will be red is 28.5%
Step-by-step explanation:
Number of red marbles = 4
Number of blue marbles = 8
Number of Green marbles = 2
Total number of marbles = 4+8+2 =14
We need to find the probability, to the nearest 10th of a percent, that both marbles drawn will be red?
The formula used will be: [tex]Probability=\frac{Number\:of\:favourable\:outcomes}{Number\:of\;possible\:outcomes}\\[/tex]
In our case, Number of favourable outcomes = 4 (as red marbles are drawn)
Number of possible outcome = 14 (Total number of marbles)
The probability will be:
[tex]Probability=\frac{Number\:of\:favourable\:outcomes}{Number\:of\;possible\:outcomes}\\\\Probability=\frac{4}{14}\\ Probability=0.2857\\[/tex]
Now, calculating nearest 10th of a percent
[tex]Probability = 0.2857*100\\Probability=28.5%[/tex]
So, the probability, to the nearest 10th of a percent, that both marbles drawn will be red is 28.5%

Lateral Area = No lateral area (choice D)Surface Area = 25.97 square inches (choice E)Volume = 12.44 cubic inches (choice A)============================================
Explanation:
Lateral area only applies to prisms and cylinders. Spheres do not have lateral sides, so there is no lateral area.
-----------------------
The radius is 1 & 7/16
Let's convert this to decimal form
1 & 7/16 = 1 + (7/16)
1 & 7/16 = 1 + 0.4375
1 & 7/16 = 1.4375
The radius is r = 1.4375 inches.
-----------------------
SA = Surface area the sphere
SA = 4*pi*r^2
SA = 4*pi*(1.4375)^2
SA = 25.9672267773281
SA = 25.97 square inches (choice E)
-----------------------
V = Volume of the sphere
V = (4/3)*pi*r^3
V = (4/3)*pi*(1.4375)^3
V = 12.4426294974698
V = 12.44 cubic inches (choice A)

A student took two national aptitude tests. The national mean and standard deviation were 325 and 100, respectively, for the first test, and 50 and 6, respectively, for the second test. The student scored 425 on the first test and 65 on the second test. Use z-scores to determine on which exam the student performed better relative to the other test takers. first exam
Answer:
Second test
Step-by-step explanation:
Given that :
FIRST TEST
Mean (m) = 325
Standard deviation (s) = 100
Score (x) = 425
SECOND TEST
Mean (m) = 50
Standard deviation (s) = 6
Score (x) = 65
Express both scores as standardized scores:
Zscore = (x - m) / s
First Score :
Zscore = (425 - 325) / 100
Zscore = 100/100 = 1
SECOND SCORE :
Zscore = (65 - 50) / 6
Zscore = 15 / 6 = 2.5
Student performed better on second test :
Zscore second > Zscore first
Suppose that 2% of produced computers by a company have defects, and defects occur independently of each other. a) Find the probability of exactly 2 defective computers in a shipment of 100 computers. b) The probability that a computer support specialist needs to test at least N computers in order to find one defective computer is 0.6676. Find N.
Answer:
a) P(exactly two defectives) = 0.2734
b) N [tex]\simeq[/tex] 55
Step-by-step explanation:
From the given information:
P(exactly two defectives) = P(X =2) = [tex]^{100}C_2 \times ( 0.02)^2 \times(1-0.02)^{100-2}[/tex]
[tex]= \dfrac{100!}{2!(100-2)!} \times ( 0.02)^2 \times(0.98)^{98}[/tex]
[tex]= 4950 \times 4 \times 10^{-4} \times 0.1380878341[/tex]
= 0.2734
Thus, P(exactly two defectives) = 0.2734
b)
To find:
P(X ≥ 1 )
let X be the random variable that obeys a binomial distribution, X represents the number of defectives,
∴
[tex]X \sim B ( N, 0.02)[/tex]
[tex]P(X \ge 1 ) = 1 - P(X < 1) \\ \\ P(X \ge 1 ) = 1 - P(X = 0)[/tex]
[tex]0.6676 = 1 - ^NC_0 \times (0.02)^0 (0.98)^N[/tex]
[tex]0.6676 = 1 - (0.98)^N[/tex]
[tex](0.98)^N = 1 - 0.6676[/tex]
[tex](0.98)^N = 0.3324[/tex]
N log (0.98) = log (0.3324)
[tex]N = \dfrac{log \ 0.3324}{log \ 0.98}[/tex]
N = 54.51824841

c. 3 bananas cost $0.99. At this rate, how much do 5 bananas cost? Explain how you know.
Answer:
$1.65
Step-by-step explanation:
You can get the cost of each banana by using the division operation. All you have to do is to divide $0.99 by 3.
0.99 ÷ 3 = $0.33Each banana costs $0.33
Now that you know the cost of each banana, you may now get the cost of 5 bananas by using the multiplication operation. All you have to do is to multiply $0.33 by 5.
0.33 x 5 = $1.65Therefore, 5 bananas cost $1.65.

Answer:
m∠ADC = 86°
Step-by-step explanation:
The sum of angles making a straight angle is 180°, so we have ...
(6x +52)° +(9x +23)° = 180°
15x = 105 . . . . . subtract 75°, collect terms, divide by °
x = 7 . . . . . . . . . divide by 15
m∠ADC = (9·7 +23)°
m∠ADC = 86°
Here given that ,
Line BDA is a straight line Angles on the line BDA are ∠BDC & ∠ADCAs we know that , sum of angles on a straight line is always equal to 180° . So ,
=> ( 6x + 52 ) ° + ( 9x + 23 ) ° = 180°
=> 15x + 75° = 180°
=> 15x = 180° - 75°
=> 15x = 105°
=> x = 105°/15
=> x = 7°
Now , by the given information , we need to find the value of ∠ADC
∠ADC = ( 9x + 23 ) °Now substituting the value of x ,
⇒ ∠ADC = 9x + 23
⇒ ∠ADC = 9 ( 7 ) + 23
⇒ ∠ADC = 63 + 23
⇒ ∠ADC = 86°

If you divide a polynomial f(x) by the factor (x - 4), the remainder will be equal to f(-4).
true or false ?
Answer:
False
Step-by-step explanation:
Given
Polynomial: f(x)
Divisor: (x - 4)
Required
Determine the remainder
To determine the remainder, we have to equate x - 4 to 0
i.e.
[tex]x - 4 = 0[/tex]
Add 4 to both sides
[tex]x - 4+4 = 0+4[/tex]
[tex]x = 0+4[/tex]
[tex]x = 4[/tex]
Substitute 4 for x in f(x) to get the remainder.
So, f(x) becomes f(4)
The result of f(4) is the remainder f(x) when divided by x - 4
Hence, the statement is false.
12 + x - 8 = 3 + 2x
Solve for x

Solve for x. I’ll give BRAINLIEST!!
Answer:
x = -7
Step-by-step explanation:
Firstly, under the rule of opposite vertical angles, you know that any angles opposite of each other in a cross section have the same degree measure.
Therefore the last remaining angle in the triangle will be 85 degrees, since it is vertically opposite of the 85 degree angle.
Next, you know that all three angles of a triangle MUST equal 180 degrees to be considered a complete triangle.
Therefore, use the equation below to solve for x:
180 = 54 + 85 + (48 + x)
x = 180 - 54 - 85 -48 = -7
