what is equivalent to sin^-1(sqrt.3/2)
Answer:
[tex]\frac{\pi }{3}[/tex]
Step-by-step explanation:
[tex]sin^{-1}(\frac{\sqrt{3} }{2})[/tex]
In, 30-60-90 degree triangle ,
the sides are in the ratio [tex]1: \sqrt{3} :2[/tex]
[tex]sin(60)= \frac{opposite}{hypotenuse}[/tex]
for 60 degree, opposite side = square root (3)
hypotenuse = 2
So [tex]sin(60)= \frac{\sqrt{3}}{2}[/tex]
when we move sin to the other side then it becomes sin^-1
[tex]60= sin^{-1}\frac{\sqrt{3}}{2}[/tex]
angle 60 degree is [tex]\frac{\pi }{3}[/tex]
[tex]sin^{-1}(\frac{\sqrt{3} }{2})=\frac{\pi }{3}[/tex]
The expression that is equivalent to sin⁻¹(sqrt. 3/2) is π/3.
What is the equivalent expression?The expression that is equivalent to another is one that yields the same output no matter the arrangement of the figures and signs.
For the expression, sin⁻¹(sqrt. 3/2), the equivalent can be obtained thus;
sin 60 = opposite/hypotenuse
sin 60 = √3/2
60 = sine⁻¹√3/2
= π/3.

the annual health insurance premium for Ms. Everett is $12,304 her employer says 70% of the premium and deducts the remainder from her paycheck Ms. Everett is paid monthly what amount is deducted from Ms. Everett paycheck for her health insurance premium.
$141.97
$307.60
$331.26
$717.73
To find the amount deducted from Ms. Everett's paycheck for her health insurance premium, calculate 70% of the annual premium, subtract the employer's contribution, and divide by 12 for the monthly deduction, resulting in $307.60. The correct answer is B.
To calculate the amount deducted from Ms. Everett's paycheck for her health insurance premium, first, find 70% of the annual premium:
70% of $12,304 = 0.70 x $12,304 = $8,612.80
The remainder that Ms. Everett must pay is the annual premium minus the employer's contribution: $12,304 - $8,612.80 = $3,691.20
Since Ms. Everett is paid monthly, divide the annual amount by 12 to find the monthly deduction: $3,691.20 ÷ 12 = $307.60
Therefore, the amount deducted from Ms. Everett's paycheck for her health insurance premium is $307.60.

Out of these, only 2 and 3 are prime numbers.
However, the sum of any two numbers less than 4 that is equal to 2 or 3 necessarily involves at least one number equal to 1, and 1 is not a prime number.

The radius of circle O is 24,and OC = 11. What is the length of AB?
Answer: The correct option is (A) 42.7 units.
Step-by-step explanation: Given that the radius of the circle center at O is 24 units and OC is 11 units.
We are to find the length of chord AB.
We have,
in the right-angled triangle OCB (m∠OCB = 90°),
OB = 24 units and OC = 11 units.
Using Pythagoras theorem in ΔOCB, we have
[tex]OB^2=OC^2+BC^2\\\\\Rightarrow BC=\sqrt{OB^2-OC^2}\\\\\Rightarrow BC=\sqrt{24^2-11^2}\\\\\Rightarrow BC=\sqrt{576-121}\\\\\Rightarrow BC=\sqrt{455}\\\\\Rightarrow BC=21.33.[/tex]
Since OC is perpendicular to chord AB, so AC = BC.
Therefore, we get
[tex]AB=AC+BC=2\times BC=2\times 21.33=42.66=42.7.[/tex]
Thus, the required length of AB is 42.7 units.
Option (A) is CORRECT.

A bargain bin contains classical and rock and CDs. There are 60 CDs in the bin. Choosing a rock CD have the same number of favorable outcomes. How many rocks CDs are in the bin
The bin should contain 30 rock CDs, which constitutes half of the total CDs (60). This conclusion is reached by dividing the total number of CDs by 2, as the question implies an equal probability of picking a rock or classical CD.
Explanation:The question pertains to the concept of probability in mathematics. Here, the total number of CDs is specified as 60. If choosing a rock CD has the same number of favorable outcomes, it means that half of the CDs are rock CDs (as the other half would then be classical CDs). So, to find the number of rock CDs in the bin, you simply divide the total number of CDs by 2. Here, 60 CDs divided by 2 equals 30. Thus, there are 30 rock CDs in the bin.

You ask randomly chosen students which candidate they will vote for in the upcoming election. A total of 50 students in the sample said they will vote for Candidate A. There are 2500 students in the school. Find the number of students in the sample who said they will vote for Candidate C. Then predict the number of students in the school who will vote for Candidate C.
Final answer:
The sample size is calculated to be 200 based on the percentage for Candidate A. From the sample, 120 students said they will vote for Candidate C. Predicting based on this sample, 1,500 students in the school will vote for Candidate C.
Explanation:
To find the number of students in the sample who said they will vote for Candidate C, we need to use the percentages given for each candidate. If Candidate A is 25%, Candidate B is 15%, and Candidate C is 60%, and knowing that 50 students in the sample voted for Candidate A, we can determine the total sample size. Since Candidate A represents 25% of the sample, we can calculate the total sample size using the equation 50 = 0.25 × (total sample size). Solving for total sample size gives us 200.
With the sample size known, we can calculate the number of students who said they will vote for Candidate C by taking 60% of 200, which is 120 students in the sample. To predict the number of students in the school who will vote for Candidate C, we use the proportion of the sample who choose Candidate C to estimate the proportion for the entire school population. Since there are 2,500 students in the school, we predict that 60% of 2,500 will vote for Candidate C, which amounts to 1,500 students.
