Answer:
Step-by-step explanation:
To answer this question, we can begin by creating factors from this equation:
(2cosθ-1)(cosθ-1)= 0.
Now, we just need to set the factors equivalent to 0 and solve:
2cosθ= 1.
cosθ= 1/2
θ= [tex]\frac{\pi }{3}[/tex], [tex]\frac{5\pi }{3}[/tex]
cosθ= 1
θ= 0, 2[tex]\pi[/tex].
Answer: Theta (θ) = 2πn, π/3 + 2πn, 5π/3 + 2πn
Step-by-step explanation:
2cos²(θ) - 3cos(θ) = -1
Let cos(θ) = u
2u² - 3u + 1 = 0
u = 1, u = 1/2
Substitute u with cos(θ) and you have your answer.

Pete is a very good student . The probability that he studies for his test and then passes it is 7/10 If the probability that Pete studies is 7/8 find the probability that Pete passes his test? given that he studied.
Answer:
The probability that Pete passes his test given that he studied = (8/10) = (4/5) = 0.80
Step-by-step explanation:
Let the event that Pete studies be S.
Let the event that Pete passes the test be P.
The probability that he studies for his test and then passes it is P(S n P) = 7/10
The probability that Pete studies is P(S) = 7/8
The probability that Pete passes his test given that he studied = P(P|S)
The conditional probability, P(A|B) is given mathematically as
P(A|B) = P(A n B) ÷ P(B)
So, the required probability, P(P|S) will be
P(P|S) = P(P n S) ÷ P(S)
P(P n S) = P(S n P) = (7/10)
P(S) = (7/8)
P(P|S) = P(P n S) ÷ P(S)
= (7/10) ÷ (7/8)
= (7/10) × (8/7)
= (8/10) = (4/5) = 0.80
The probability that Pete passes his test given that he studied = (8/10) = (4/5) = 0.80
Hope this Helps!!!
Can somebody please tell me the answer to this
Answer:
x= 60°.
Step-by-step explanation:
To solve this problem, we must figure out the measure of the angles inside a hexagon. We can do this using the Interior Angle formula S = (n - 2)·180.
When we plug the number of sides a hexagon has into this equation, we get a total sum of 720.
To get the measure of each angle, we simply divide 720 by 6, giving us a measure of 120 per angle. Since we know the measure of the interior angles, we can solve for angles of the triangle using Supplementary angles.
180-120= 60°.
We know that the two angles of the triangle against the hexagon are 60°, but what about the other angle?
All you need to do is subtract the two angles from 180 to get you the angle of 'x'.
180-2(60°)= 60°.

Eff scored a 23/25 on his math test, Maria scored 21/24 on her math test and Jake scored 17/20 on his math test. Who had the highest score? Explain how you know.
Answer:
Eff
Step-by-step explanation:
Fraction is a part of a whole, telling us how many parts of a whole we have. It can be converted to percentage or decimal.
Eff scored a 23/25 on his math test. Converting to percentage, eff score = 23/25 * 100% = 92%
Maria scored 21/24 on her math test. Converting to percentage:
Maria score = 21/24 * 100% = 87.5%
Jake scored 17/20 on his math test, converting to percentage:
Jake score = 17/20 * 100% = 85%
The person with the highest score has the highest percentage which is Eff with 92%.
Answer:
Eff had the highest score.
Step-by-step explanation:
The approach to determine who get the same score is converting each fraction to an arbitrary scale, which is 100 for this problem. Now, the conversions are presented below:
Eff
[tex]x = \frac{23}{25}\times 100[/tex]
[tex]x = 92[/tex]
Maria
[tex]x = \frac{21}{24}\times 100[/tex]
[tex]x = 87.5[/tex]
Jake
[tex]x = \frac{17}{20}\times 100[/tex]
[tex]x = 85[/tex]
Eff had the highest score.

PLS HELP!! I’LL GIVE U 5 stars
Answer:
A). 81 students
B). 18 students
C). 10 students
Step-by-step explanation:
Let S = {All students of 8th grade} = 91
A = {Students in Art} = 68
B = {Students in band} = 31
Part A : A∪B = A + B - A∩B
A∪B = 68 + 31 - 18
A∪B = 81
A∪B represents the total number of students enrolled in art and band.
Part B : A∩B = 18
A∩B represents the number of common students enrolled in art and band.
Part C: ~(A∪B) = S - A∪B
~(A∪B) = 91 - 81
~(A∪B) = 10
~(A∪B) represents the number of students enrolled neither in art nor in band.

In how many ways can the first 4 guests arrive at a party if 15 guests have been invited.
Answer:
The first 4 guests can arrive in 32,760 ways.
Step-by-step explanation:
The order in which the guests arrive is important. For example, A,B,C,D is a different outcome to B,A,C,D. So we use the permutations formula to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]
In this question:
4 guests from a set of 15. So
[tex]P_{(15,4)} = \frac{15!}{(15-4)!} = 32760[/tex]
The first 4 guests can arrive in 32,760 ways.
Answer:
the first 4 guests can arrive in 32,760 ways.
Step-by-step explanation:
how many ways can the first 4 guests arrive at a party if 15 guests have been invited.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]
4 guests from a set of 15
P(15,4) = 15 * 14 * 13 * 12
= 32760
Therefore, the first 4 guests can arrive in 32,760 ways.

Caleb went to Kroger and spent $83.47 on groceries. He had a coupon for $1.99 off bottled water and $0.89 off organic strawberries. How much did Caleb spend at Kroger?
Answer:
$86.35
Step-by-step explanation:
Total amount he spent at Kroger
= $83.47 on groceries. +coupon for $1.99 off bottled water + $0.89 off organic strawberries
= 83.47+0.89+1.99
= $86.35
Final answer:
After applying coupons for bottled water and organic strawberries, Caleb spent a total of $80.59 at Kroger. The discounts of $1.99 and $0.89 were subtracted from the initial spend of $83.47.
Explanation:
Caleb went to Kroger and initially spent $83.47 on groceries. He had two coupons: one for $1.99 off bottled water and another for $0.89 off organic strawberries. To calculate how much Caleb spent after using his coupons, we need to subtract the value of the coupons from the initial amount.
First, we calculate the total discount by adding the two coupon values:
$1.99 for bottled water
$0.89 for organic strawberries
Total discount = $1.99 + $0.89 = $2.88.
Then, we subtract this total discount from the initial spend:
$83.47 - $2.88 = $80.59
Therefore, Caleb spent $80.59 at Kroger after applying his coupons.
10% of 5000 is......
And 5% of 5000 is.....
Step-by-step explanation:
• 10% of 5000
[tex] = 10\% \times 5000 \\ = \frac{10}{100} \times 5000 \\ = 10 \times 50 \\ = 500[/tex]
So, 10% of 5000 is 500
• 5% of 5000
[tex] = 5\% \times 5000 \\ = \frac{5}{100} \times 5000 \\ = 5 \times 50 \\ = 250[/tex]
So, 5% of 5000 is 250
10% of 5000 is 500, and 5% of 5000 is 250. These calculations are done by converting the percentages into decimals and then multiplying by the total amount.
Write the percentage as a decimal: 10% = 0.10.Multiply the decimal by the total amount: 0.10 * 5000 = 500.Therefore, 10% of 5000 is 500.
To calculate 5% of 5000, you can take half of the 10% value or multiply 5000 by 0.05:
Write the percentage as a decimal: 5% = 0.05.Multiply the decimal by the total amount: 0.05 * 5000 = 250.Therefore, 5% of 5000 is 250.

Answer:
6, -5/2, 7/4
Step-by-step explanation:
The required slope that shows given points are not collinear is 6, -5/2, and 7/4.
What is the slope of the line?
The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
Here,
m = (y₂ - y₁) / (x₂ - x₁) - - - - (1)
Substitute points C(1, 1), and D(3, -4) in the above equation 1,
m = -4 -1 / 3 - 1
m = -5/2
Substitute points D(3, -4) and E(5, 8) in the above equation 1,
m = 8 + 4 / 5 - 3
m = 12 / 2
m = 6
Substitute points C(1, 1) and E(5, 8) in the above equation 1,
m = 8 - 1 / 5 - 1
m = 7 / 4
Thus, the required slope that shows given points are not collinear are 6, -5/2, and 7/4.

Câte diagonale are un poligon cu 5 laturi, dar cu 6 laturi?
Your question isn't clear. But I infer this is the clear rendering of it;
How many diagonals does a polygon have with 5 sides, but with 6 sides?
Answer:
a. For 5 sides= 5
b. For 6 sides= 9
Step-by-step explanation:
Remember, this is the formula to calculate the number of diagonals of a polygon;
n (n-3) / 2 where n is the sides.
Thus,
for 5 sides= 5 (5-3) /2
= 5 (2) /2 = 10/2= 5
for 6 sides= 6 (6-3) /2
= 6 (3) /2 = 18/2= 9
