Answer:
[tex] x = \frac{\sqrt{6}}{2} [/tex]
Step-by-step explanation:
Reference angle = 45°
Opposite side = x
Hypotenuse = √3
Use the following trigonometric ratios formula to find x:
[tex] sin(\theta) = \frac{opp}{hyp} [/tex]
Plug in the values
[tex] sin(45) = \frac{x}{\sqrt{3}} [/tex]
Multiply both sides by √3
[tex] \sqrt{3}*sin(45) = x [/tex]
[tex] \sqrt{3}*\frac{\sqrt{2}}{2} = x [/tex]
[tex] \frac{\sqrt{3*2}}{2} = x [/tex]
[tex] \frac{\sqrt{6}}{2} = x [/tex]

Andre has a summer job selling magazine subscriptions. He earns $25 per week plus $3 for every subscription he sells. Andre hopes to make at least enough money this week to buy a new pair of soccer cleats. The least expensive pair of cleats Andre wants costs $68.
a.) Write an inequality to find the number of subscriptions he needs to sell so that he can buy a pair of cleats.
b.) Solve the inequality from part (a).
c.) Interpret (what does it mean) and graph the solution.
Answer:
68≥25+3x
x≥15
Step-by-step explanation:
the overall goal is to have $68, so the goal needs to be less then or equal to the weekly $25 plus each additional subscription at $3 (x represents the needed amount of subscriptions he sells) the inequality would look something like 68≥25+3x because he wants the money this week.
to solve the inequality you would subtract the 25 from the 68, leaving you with 43≥3x as the new inequality, now you need to divide both sides by 3. Which comes out to 14.33333..... since we cant sell a fraction of a subscription you must round up giving you the new inequality of x≥15
this means that in order for Andre to get the cleats this week, he must sell at least 15 subscriptions
hope this helped
a.) 25x + 3y ≥ 68
b.) x = 1, y = 43
c.) As x increases, y decreases
What is a linear inequality?A linear inequality is a mathematical relation which gives the range of values a variable or a function can take.
Given,
Wage per week= $25
Subscription earning = $3
Let x and y be the number of weeks and number of subscriptions.
Therefore, 25x + 3y ≥ 68
Hence, 25x + 3y ≥ 68 is the required inequality.
Let x = 1
Therefore minimum value of y = 43.

Given Z1 and Z2, find the
distance between them.
Z1 = 2 – 3i and Z2 = 4 + i
Answer:
The distance between given points is: √20
Step-by-step explanation:
The given numbers are complex numbers. In order to find the distance between two numbers in complex plain, their difference is taken and then modulus is applied.
Given numbers are:
[tex]z_1 = 2-3i\\z_2 =4+i[/tex]
The difference will be calculated as:
[tex]z_2-z_1 = (4+i)-(2-3i)\\= 4+i-2+3i\\=2+4i[/tex]
The distance will be:
[tex]d = \sqrt{(2)^2+(4)^2}\\= \sqrt{4+16}\\=\sqrt{20}[/tex]
Hence,
The distance between given points is: √20

Answer:
The value of x = 10.
Step-by-step explanation:
From the given triangle,
The value of angle M = (3x + 28)°The value of angle K = (5x - 18)°The value of angle L = 90°We know that the sum of a triangle is 180°.
i.e.
K + L + M = 180°
(5x - 18)° + 90° + (3x + 28)° = 180°
[tex]5x-18+90+3x+28=180[/tex]
[tex]5x+3x-18+90+28=180[/tex]
[tex]8x-18+90+28=180[/tex]
[tex]8x+100=180[/tex]
[tex]8x=80[/tex]
[tex]\frac{8x}{8}=\frac{80}{8}[/tex]
[tex]x=10[/tex]
Therefore, the value of x = 10

A 2.5-meter piece of framing lumber has been used to cut a piece 1.65 meters long. How much of the original piece of lumber remains, in meters?
Answer:
0.85 of the original piece of lumber remains.
Step-by-step explanation:
Well, this lumber piece of lumber started as 2.5 meters long. Then, a 1.65 meter piece was cut off of it. All we need to do is subtract.
2.5 - 1.65 =
2.50 - 1.65 = 0.85.
Therefore, 0.85 of the original piece of lumber remains.

A random sample of 300 circuits generated 13 defectives. Use the data to test the hypothesis Upper H Subscript 0 Baseline colon p equals 0.05 against Use . Find the P-value for the test.
Complete Question
A random sample of 300 circuits generated 13 defectives. a. Use the data to test
[tex]H_o : p = 0.05[/tex]
Versus
[tex]H_1 : p \ne 0.05[/tex]
Use α = 0.05. Find the P-value for the test
Answer:
The p-value is [tex]p-value = 0.5949[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 300
The number of defective circuits is k = 13
Generally the sample proportion of defective circuits is mathematically represented as
[tex]\^ p = \frac{k}{n}[/tex]
=> [tex]\^ p = \frac{13}{300}[/tex]
=> [tex]\^ p = 0.0433[/tex]
Generally the standard Error is mathematically represented as
[tex]SE = \sqrt{\frac{p(1- p)}{n} }[/tex]
=> [tex]SE = \sqrt{\frac{0.05(1- 0.05)}{300} }[/tex]
=> [tex]SE = 0.0126[/tex]
Generally the test statistics is mathematically represented as
[tex]z = \frac{\^ p - p }{SE}[/tex]
=> [tex]z = \frac{0.0433 - 0.05 }{0.0126}[/tex]
=> [tex]z = -0.5317[/tex]
From the z table the area under the normal curve to the left corresponding to -0.5317 is
[tex](P < -0.5317 ) = 0.29747[/tex]
Generally the p-value is mathematically represented as
[tex]p-value = 2 * P(Z < -0.5317 )[/tex]
=> [tex]p-value = 2 * 0.29747[/tex]
=> [tex]p-value = 0.5949[/tex]

Maria and Sarah were in charge of selling tickets to the class play. Maria sold 91
tickets and Sarah sold 70 tickets. What is the ratio of the number of tickets Maria sold
to the total number of tickets sold?
Answer:
Maria sold 56.5% of the total quantity of tickets sold.
Step-by-step explanation:
Given that between Maria and Sarah they both sold 161 tickets (91 + 70), and that of those 161 Maria sold 91 while Sarah sold 70, to determine the percentage of tickets that Maria sold over the total amount, the following crossed multiplication must be performed:
161 = 100
91 = X
((91 x 100) / 161) = X
9,100 / 161 = X
56.5 = X
Therefore, Maria sold 56.5% of the tickets sold.
When asked about favorite Thanksgiving leftovers, 9% of the people said turkey and 7/100 said mashed potatoes. Which food is more popular? How do you know?
Answer:
Turkey is more popular.
Step-by-step explanation:
If in the survey about which is the favorite food on Thanksgiving, 9% answered turkey and 7/100 answered marshed potatoes, the most popular food among both is turkey.
This is so because in the case of marshed potatoes, the fact that 7 out of 100 choose this food implies that 7% of those surveyed designate it as their favorite, which is less than the 9% who choose turkey as such.
