Answer:
sin2θ = [tex]\frac{1320}{3721}[/tex]
Step-by-step explanation:
Given
sinθ = [tex]\frac{11}{61}[/tex] = [tex]\frac{opposite}{hypotenuse}[/tex]
This is a right triangle with legs 11 and x ( adjacent ) and hypotenuse 61
Using Pythagoras' identity in the right triangle to find x
x² + 11² = 61²
x² + 121 = 3721 ( subtract 121 from both sides )
x² = 3600 ( take the square root of both sides )
x = [tex]\sqrt{3600}[/tex] = 60
Then cosθ = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{60}{61}[/tex]
Using the identity
sin2θ = 2sinθcosθ , then
sin2θ = 2 × [tex]\frac{11}{61}[/tex] × [tex]\frac{60}{61}[/tex] = [tex]\frac{1320}{3721}[/tex]
Right triangle ABC is shown below.

m3=112° (vertically opposite angles are equal)
m1= 112°+ m1 =180 (the sum of interior angles measure 180°)
hence, m1 = 180 - 112°

Camille buys a cake for $\$24.99$ . She also buys $12$ brownies. Each brownie costs the same amount. She spends $\$39.99$ on the cake and the brownies. Camille finds the cost of each brownie by calculating $(39.99\ -\ 24.99)\ \div\ 12$ . Tanya finds the cost of each brownie by solving the equation $39.99\ +\ 12b\ =\ 24.99$ , where $b$ is the cost of each brownie. Which approach uses the sequence of operations necessary to find the cost of each brownie: Camille’s, Tanya’s, both, or neither? Explain why. Respond in the space provided.
The cost of each brownie is $1.25
Equation and expressionsLet the cost of each brownies be x
If she buys 12 brownies and each brownie costs the same amount, the cost of 12 brownies will be 12x
To find the value of x;
39.99 = 24.99 + 12x
12x = 15
x = 15/12
x = $1.25
Hence the cost of each brownie is $1.25

At airports, some people are randomly selected for extra security screening. It is claimed that 25% of all passengers are screened. A recent flight contained 5 passengers in first class, none of whom were chosen for additional screening.
We want to perform a simulation to estimate the probability that 0 out of 5 passengers would be chosen in a random selection process.
Let 0 = chosen for extra screening, and 1, 2, and 3 = not chosen for extra screening. Skip the digits 4 through 9. Using the digits shown below, how many passengers, out of 5, are selected for extra screening?

Which of the following must be true?
A 95% confidence interval for will include the value 0.022.
A 99% confidence interval for will include the value 1.
None of these is necessarily true.
A 99% confidence interval for will include the value 0.022.
A 95% confidence interval for will include the value 1.
Answer:
A
Step-by-step explanation:
The true statement is
A 99% confidence interval for will include the value 1.
What is Confidence Interval?The range of values that we observe in our sample and for which we anticipate finding the value that accurately reflects the population is referred to as a confidence interval.
Given:
[tex]H_0: \mu = 1\\H_\alpha : \mu \neq 1[/tex]
P= 0.022
If the P- value is smaller than significance level, then the null hypothesis is rejected.
P< 0.05 - 5% Reject [tex]H_0[/tex]
P> 0.01 = 1% Fail to Reject [tex]H_0[/tex]
A 95% Confidence interval correspond with a significance test at the 5%
significance level.
A 99% Confidence interval correspond with a significance test at the 1%
significance level.
If the Significance test was Significant then the interval does not contain the value mentioned in the Hypothesis.
95% CI does not contains 1.
99% CI contains 1.

write the equation of a line perpendicular to y= -1/3x + 5 and passes through the point (6, 4).
Answer:
y = 3x - 14
Step-by-step explanation:
Perpendicular lines will have a opposite reciprocal slope, so the slope will be 3.
Plug in the slope and given point into y = mx + b, then solve for b:
y = mx + b
4 = 3(6) + b
4 = 18 + b
-14 = b
Plug in the slope and y intercept into y = mx + b
y = 3x - 14
So, the equation of the line is y = 3x - 14
help me please ? i need help with this table
Answer:
The last option
Step-by-step explanation:
You can find the slope by using this equation : y2-y1/x2-x1. We can choose any two y coordinates and any two x coordinates to find this. For instance, you can write this as -3-(-2.25)/0-(-1). Now, we can solve.
-3-(-2.25)/0-(-1)
-3+2.25/0+1
-0.75/1
-0.75
-0.75 in fraction form is -3/4.
I'm not quite sure how to calculate the y-intercept, but we know the slope, and that's all we need for this problem (the slope number is next to the x). This makes our answer the last option. Hope this helps!
