There is a spinner with 15 equal areas, numbered 1 through 15. If the spinner is spun one time, what is the probability that the result is a multiple of 5 or a multiple of 3?
Answer:
1/15
Step-by-step explanation:
The probability of spinning a number on a spinner with 15 equal areas that is a multiple of 5 or a multiple of 3 is 7/15, as there are 7 favorable outcomes (3, 5, 6, 9, 10, 12, 15) out of 15 possible results.
Explanation:The question asks for the probability of spinning a number that is either a multiple of 5 or a multiple of 3 on a spinner with 15 equal areas numbered 1 through 15. To solve this, we need to identify the multiples of each within the range of numbers on the spinner and then use the principles of probability to find the chances of landing on one of those multiples when the spinner is spun once.
The multiples of 5 between 1 and 15 are 5, 10, and 15. The multiples of 3 are 3, 6, 9, 12, and 15. Note that 15 is a multiple of both 5 and 3, so it should only be counted once. To avoid overcounting, we will list each multiple only once, which gives us the numbers 3, 5, 6, 9, 10, 12, and 15. The probability of landing on any specific number on the spinner is 1 out of 15 because there are 15 equally likely outcomes.
Since we have 7 such favorable outcomes, the probability is calculated as the number of favorable outcomes over the total number of possible outcomes, which is 7/15. So, the probability of spinning a number that is a multiple of 5 or a multiple of 3 on one spin is 7/15.

Which of the following shows the true solution to the logarithmic equation 3log2(2x)=3
A.x=-1
B.x=1
C. x=-1 and x=1
D. x0 x=-1 and x=1
Answer:
Option B is correct.
Step-by-step explanation:
Given logarithmic equation,
[tex]3log_2(2x)=3[/tex]
[tex]log_2(2x)=\frac{3}{3}[/tex]
[tex]log_2(2x)=1[/tex]
since base of the log function is 2.
we take power of 2 on both sides.
[tex]2^{log_2(2x)}=2^1[/tex]
2x = 2
x = 1
Therefore, Option B is correct.

The circumference of the parachute is Option A (100.48 feet).
To find the circumference of the parachute, we use the circumference formula for a circle:
C = 2πr
Given the radius (r) is 16 feet, we substitute it into the formula:
C = 2π(16) = 32π
Using the approximate value of π (3.1416), we get:
C ≈ 32 × 3.1416 = 100.48 feet
Thus, the measurement closest to the circumference of the parachute in feet is 100.48 feet (Option A).

The probability of a 4-digit lock code without all even digits is
Answer:
it's 24, 3000, and 3000/3024
Step-by-step explanation:
The probability for a 4-digit lock code using numbers 1-9 with no repeats and not all even is 2,904/3,024.
Explanation:To solve this, we need to find the total number of possible 4-digit lock codes using digits 1-9 with no repeats and not all even, then divide it by the total number of 4-digit lock codes using digits 1-9 with no repeats. Specifically, the lock code includes 5 different even numbers (2,4,6,8), and 4 different odd numbers (1,3,5,7,9). If the lock code is all even, we will have 5*4*3*2 = 120 possibilities. However, the total possibilities for 4-digit lock codes are 9*8*7*6 = 3,024. Thus the number of codes that are not all even digits is 3,024 - 120 = 2,904. Therefore, the probability for a 4-digit lock code not having all even digits is 2,904/3,024.

Given that AB is the bisector of DC. The third options of all the options are True.
B is the midpoint of DC.
In geometry, to bisect an entity means to disassociate it into two equal parts. A bisector is a line, ray, or segment that divides an entity into two equal parts. For illustration, a line that bisects an angle divides the angle into two angles with equal measures. A segment that bisects a line segment divides the line segment into two segments with equal lengths. A ray that bisects an angle extends from the vertex of the angle and divides the angle into two angles with equal measures.
As it is given that AB is the bisector of DC,
therefore, B, being the foot of AB on CD is the midpoint of DC.
Since DC is bisected by AB,
therefore, [tex]\angle[/tex] ABD = [tex]\angle[/tex] ABC.

Find the fifth roots of 32(cos 280° + i sin 280°).
Correct Answer:
z1= 2(cos 56 deg + i sin 56 deg)
z2= 2(cos 128 deg + i sin 128 deg)
z3 = 2(cos 200 deg + i sin 200 deg)
z4 = 2(cos 272 deg+ i sin 272 deg)
z5 = 2(cos 344 deg+ i sin 344 deg)
Step-by-step explanation:
De Moivre's Theorem--> e^i theta = cos theta + i sin theta
The fifth root of 32 is 2 and 280/5 is 56
z1= 2(cos 56 deg + i sin 56 deg)
360deg/ 5 = 72 deg
(If it was asking for cubed root u would do 360/3. whatever the root is you divide that by 360)
z2= 2(cos 56 + 72) + (i sin 56 + 72)
z2= 2(cos 128 deg + i sin 128 deg)
z3 = 2(cos 128 + 72) + ( i sin 128 + 72)
z3 = 2(cos 200 deg + i sin 200 deg)
z4 = 2(cos 200 + 72) + (i sin 200 + 72)
z4 = 2(cos 272 deg + i sin 272 deg)
z5 = 2(cos 272 + 72) + (i sin 272 + 72)
z5 = 2(cos 344 deg + i sin 344 deg)

−6

9
Final answer:
The solution to f(g(x)) when x = 9 is -6.
Explanation:
In mathematics, a function is a relation between a set of inputs (called the domain) and a set of possible outputs (called the codomain), where each input is related to exactly one output.
Given:
f(x) = x2 - 4x - 3, g(x) = (x + 3) / 4
To find f(g(x)) when x = 9:
Calculate g(9): Substitute x = 9 into g(x) to get (9 + 3) / 4 = 12 / 4 = 3Substitute g(9) into f(x): Substitute g(9) = 3 into f(x) to get f(3) = 32 - 4(3) - 3 = 9 - 12 - 3 = -6Therefore, f(g(x)) when x = 9 is -6.
