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

Answer:
616
Step-by-step explanation:
first 2 2/3 divided by 1/3 = 8 so it is 8 cubes in that direction, then 3 1/3 divide by 1/3 = 11 so 11 cubes in that direction, which gives us a layer. 2 1/3 divided by 1/3 is 7 so we need 7 layers. multiply 8 by 11 to get the number of cubes per layer, which is 88. then 88 times 7= 616.

Help!!!!!
Step-by-step explanation:
m<2=49° (vertically opposite angles are equal)
m3=112° (vertically opposite angles are equal)
m1= 112°+ m1 =180 (the sum of interior angles measure 180°)
hence, m1 = 180 - 112°
m1= 68°

After checking that conditions are met, you perform a significance test of 0:=1 versus :≠1 . You obtain a -value of 0.022.
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.

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]

Aeronautical researchers have developed three different processes to pack a parachute. They want to compare the different processes in terms of time to deploy and reliability. There are 1,200 objects that they can drop with a parachute from a plane. Using a table of random digits, the researchers will randomly place the 1,200 items into three equally sized treatment groups suitable for comparison.
How should the items be labeled to select the process groups using a table of random digits?
A 1–3
B 1–1200
C 0000–1200
D 0000–1199
The items should be labeled (a) 1 - 3 to select the process groups
How to determine the label?The given parameters are:
Processes = 3Objects = 1200From the question, we understand that the objects are to be classified.
This means that the objects would be classified based on the 3 process.
The 3 processes can be labeled 1 - 3
Hence, the label of the process group is (a) 1 - 3
