Answer:
[tex]\huge\boxed{\text{E. } \frac{1}{2} }[/tex]
Step-by-step explanation:
When finding the cosine of an angle, we need to note what each terms mean.
Using the acronym SOH CAH TOA, we know that the
Cosine of an angle will be it's
Adjacent side divided by the
Hypotenuse.
The side adjacent to the 60° angle is 1, and the hypotenuse of the triangle is 2. Therefore, the adjacent over the hypotenuse is [tex]\frac{1}{2}[/tex], making the cos of 60°
[tex]\frac{1}{2}[/tex].

the probability of randomly selecting a four-person committee consisting entirely of canadians from a pool of 11 americans and 18 canadian
Answer:
[tex]Probability =0.1744[/tex]
Step-by-step explanation:
Given
Total
[tex]American = 11[/tex]
[tex]Canadian = 18[/tex]
Selection
[tex]American = 0[/tex]
[tex]Canadian = 4[/tex]
Required
Determine the probability of selecting a 4 committee member that are Canadian.
First, we calculate total possible selection.
[tex]Total = American + Canadian[/tex]
[tex]Total = 11 + 18[/tex]
[tex]Total = 27[/tex]
Number of ways to select 4 from 27 is:
[tex]^{27}C_4 = \frac{27!}{(27-4)!4!}[/tex]
[tex]^{27}C_4 = \frac{27!}{23!4!}[/tex]
[tex]^{27}C_4 = \frac{27*26*25*24*23!}{23!4!}[/tex]
[tex]^{27}C_4 = \frac{27*26*25*24}{4!}[/tex]
[tex]^{27}C_4 = \frac{27*26*25*24}{4*3*2*1}[/tex]
[tex]^{27}C_4 = \frac{421200}{24}[/tex]
[tex]^{27}C_4 = 17550[/tex]
Next, we calculate ways of selecting 4 Canadians from 18 is:
[tex]^{18}C_4 = \frac{18!}{(18-4)!4!}[/tex]
[tex]^{18}C_4 = \frac{18!}{14!4!}[/tex]
[tex]^{18}C_4 = \frac{18*17*16*15*14!}{14!4!}[/tex]
[tex]^{18}C_4 = \frac{18*17*16*15}{4!}[/tex]
[tex]^{18}C_4 = \frac{18*17*16*15}{4*3*2*1}[/tex]
[tex]^{18}C_4 = \frac{73440}{24}[/tex]
[tex]^{18}C_4 = 3060[/tex]
The required probability is:
[tex]Probability =\frac{3060}{17550}[/tex]
[tex]Probability =0.1744[/tex]
Joey and Emily's teacher gave them each a triangle divided into three parts-A, B, and C-which looked like the triangle
shown below. They were told to cut the pieces apart and rearrange them into a figure that will prove that the sum of the
interior angles of a triangle is always equal to 180°.
Answer:Emily, because all the vertices of the original are touching

Solve for x if y = 3 in the equation 2x + 3y = 12 *
Answer:
x = 3/2 or 1.5
Step-by-step explanation:
y = 3 in the equation 2x + 3y = 12
Substitute 3 in for y.
2x + 3(3) = 12
Multiply.
2x + 9 = 12
Subtract 9 from both sides.
2x + 9 - 9 = 12 - 9
2x = 3
Divide both sides by 2.
2x ÷ 2 = x
3 ÷ 2 = 3/2 or 1.5
x = 1.5
Answer:
X = 1.5
Step-by-step explanation:
So we know that Y = 3 and 3 x 3 = 9, then we need to get the difference of 9 to 12
12 - 9 = 3
we now know that x will equal 3, so 2 x 1.5 = 3, and 3 + 9 = 12
(Full equation)
2 x 1.5 + 3 x 3 = 12
Solve.
X = -7
4x - 4y = 12
(x,y)
Answer:
(-7, -10)
[tex]x=-7\\y=-10[/tex]
Step-by-step explanation:
[tex]4x-4y=12[/tex]
Substitute x for -7.
[tex]4(-7)-4y=12[/tex]
Multiply 4 by -7.
[tex]-28-4y=12[/tex]
Add 28 on both sides.
[tex]-4y=40[/tex]
Divide -4 on both sides.
[tex]y=-10[/tex]
A ball is launched upward from the ground with an initial velocity of 20 ft/s.

180-62-53 = 65
in the figure, AC=20cm CD=22cm and AE=16cm find the length of BD.
Answer:
17.6 cm
Step-by-step explanation:
Area of triangle equals to half of the base times height, i.e. A = 1/2 × b × h.
1/2 x 22 x 16 = 1/2 x 20 x BD
BD = (1/2 x 22 x 16) / (1/2 x 20)
BD = 17.6 cm
In which number is the value of the seven equal
to (7x1/
1,000)?
A 36.074
B 7,256.05
C 64.387
D 769.21
Answer:
It would be C, 64.387
Step-by-step explanation:
First, you have to solve 7x1/1000. This equal to 7/1000 which should be converted into decimal form (since all the answers are in decimal form). 7/1000 is 0.007 in decimal form.
It is 0.007 since in 7/1000, the denominator is 1000, making 7 in the thousandths place (the 3rd digit to the right of the decimal point).
The only number that contains 0.007 is the 3rd one, making it your answer.

Angela works at a job that pays $9.46 per hour. She works for 30 hours per week.
Compute the total amount that Angela makes in one week.
$
283.8
Assume that there are four weeks per month. Compute the total amount Angela makes per month.
$
1,135.2
Angela is using the Quantitative Reasoning Process to make a decision. She needs to know how much she makes in one year. Sometimes the values we get from our calculations depend on the assumptions we make. The following questions show that Angela will get different values for the amount she makes in a year depending on the assumption she chooses.
Assume that Angela gets paid once per week. Multiply the amount she makes in one week by 52 to find the total she will make in one year.

After years of maintaining a steady population of 32,000, the population of a town begins to grow exponentially. After 1 year and an increase of 8% per year, the population is 34,560. Which equation can be used to predict, y, the number of people living in the town after x years? (Round population values to the nearest whole number.)
y = 32,000(1.08)x
y = 32,000(0.08)x
y = 34,560(1.08)x
y = 34,560(0.08)x
