Find the coordinates of the point (x, y)
shown on the unit circle.
X=?
Y=?
Answer:
the coordinates of the point of x and y is -1÷ 2 and -√3÷ 2
Step-by-step explanation:
The computation of the coordinates of the point is shown below:
The angle is
= 4π ÷ 3
The radius is 1 unit
Now
x = rcos[tex]\theta[/tex], and y = rsin[tex]\theta[/tex]
Now
x = 1cos(4π ÷ 3) = -1÷ 2
y = 1sin(4π ÷ 3) = -√3÷ 2
hence, the corordinates of the point of x and y is -1÷ 2 and -√3÷ 2
Answer: x= -1/2 y= -root3/2

The American Heart Association is about to conduct an anti-smoking campaign and wants to know the fraction of Americans over 33 who smoke. Step 1 of 2: Suppose a sample of 1267 Americans over 33 is drawn. Of these people, 913 don't smoke. Using the data, estimate the proportion of Americans over 33 who smoke. Enter your answer as a fraction or a decimal number rounded to three decimal places.
Answer:
The estimate for the proportion of Americans over 33 who smoke is 0.28.
Step-by-step explanation:
Proportion of Americans over 33 who smoke.
Number who smoke divided by the size of the sample.
In this question:
Sample of 1267.
913 don't smoke, so 1267 - 913 = 354 smoke. Then
[tex]p = \frac{354}{1267} = 0.28[/tex]
The estimate for the proportion of Americans over 33 who smoke is 0.28.

Find the amount of tax and the tax rate. Round to nearest hundredth of a percent.
Cost of item: $52
Selling price: $71.97
Answer:
Amount of Tax = $19.97
Tax Rate = 28%
Step-by-step explanation:
Amount of Tax = $71.97 - $52 = $19.97
Tax Rate = 19.97/71.97 × 100
= 0.28 × 100 = 28%

Step-by-step explanation:
Jenny has overdrawn her bank account by $48.38. She makes a withdrawal of $10.25 and then makes a deposit of $60. What is the amount of money in Jenny's account after with withdrawal and deposit?
Over drawn means negative.
So she is at -43.38 then withdraws ( takes out) 10.25
Now her account is at -43.38-10.25 = -53.63
She than adds 60
Her final amount is -53.63 + 60 = $6.37
Answer:
-48.38-10.25= -58.63
-58.63 + 60= 1. 37

Group of answer choices
A. 49x2 − 28x + 16
B. 9a2 − 30a + 25
C. 25b2 − 45b − 81
D. 16x2 − 24x − 9
Answer:
The answer is B. 9a2-30a+25
Step-by-step explanation:
First of all, the second sign is going to be +, so you can toss out C and D without checking.
Then you take the square root of the two ends, multiply them, multiply by two and see if it matches.
sqrt(49) * sqrt(16) = 7 * 4 = 28
28 * 2 = 56
56 <> 28
So toss A.
sqrt(9) * sqrt(25) = 3 * 5 = 15
15 * 2 = 30
So the answer is B
(3a - 5)^2 = 9a^2 - 30a + 25

Tom simplified an expression in three steps, as shown:
x to the power of negative 2 multiplied by y to the power of 4, over y multiplied by x to the power of 4 multiplied by x to the power of 4 multiplied by y to the power of negative 2, the whole to the power of 4
Step 1:
x to the power of 2 multiplied by y to the power of 8, over y to the power of 4 multiplied by x to the power of 8 multiplied by x to the power of 8 multiplied by y to the power of 2
Step 2:
x to the power of 2 multiplied by y to the power of 8, over y to the power of 6 multiplied by x to the power of 16.
Step 3:
x to the power of negative 13 multiplied by y squared
Which is the first incorrect step and why?
Step 1, all the exponents are increased by 4
Step 2, the exponents of the same base are added during multiplication
Step 3, the exponents of the same base are subtracted during division
Step 3, all the exponents are added during division

Find the sum of the first 36 terms of the following series, to the nearest integer. 9,12,15
Answer:
3885
Step-by-step explanation:
The sum of the first 35 terms will be 3885.
What is an arithmetic progression?The sequence in which every next number is the addition of the constant quantity in the series is termed as the arithmetic progression.
A number series is a number-based sequence. In the number series questions, we must identify the rules that lead to the formation of a number series.
Given that the series is 9, 15, 21, ..., The 35th term of the sequence will be calculated as,
Sn = n /2 [ ( 2a + ( n - 1 ) d]
Sn = 35 / 2 [ ( 2 x 9 + ( 35 - 1 ) 6)]
Sn = 35 /2 { 18 + ( 34 x 6 ) ]
Sn = 35 / 2 x 222
Sn = 3885
Hence, the sum of the 35 terms of the series will be 3885.

Determine the area of the composite figure.
Answer:
240
Step-by-step explanation:
Split the firgue into shapes you know
rectangle and Trapezoid
A = bh
A = 10×6
A = 60
A = 1/2h(b+b)
A = 1/2×12(10+20)
A = 6(30)
A = 180
180 + 60 = 240
240
Answer:
420 cm²
Step-by-step explanation:
Area of composite shapes
To calculate the area of a composite shape you must divide the shape into rectangles, triangles, or other shapes you can find the area of and then add the areas back together. You may have to calculate missing lengths before finding the area of some of the shapes. Other composite shapes may have cut-out sections.Solve
To find the composite area of two or more shapes, simply find the area of each shape and add them together.
So,
18 cm × 20 cm = 360
10 cm × 6 cm = 60
Now, add the results together
360 + 60 = 420
Therefore, the area of the composite figure is 420 cm²

To test whether or not there is a difference between treatments A, B, and C, a sample of 12 observations has been randomly assigned to the 3 treatments. You are given the results below. Treatment Observation A 20 30 25 33 B 22 26 20 28 C 40 30 28 22 The null hypothesis for this ANOVA problem is
Answer:
H0 : //μA = μB = μC
Step-by-step explanation:
Given the data:
Treatment | Observation
A | 20 | 30 | 25 | 33
B | 22 | 26 | 20 | 28
C | 40 | 30 | 28 | 22
To test whether there is a difference between the group means of a sample ; the ANOVA test is employed ;
The appropriate hypothesis test:
The alternative hypothesis will habour the notion that there is a difference in sample means while the alternative will be opposite, that is, no difference exists in the sample means for the three treatments :
Null hypothesis ; H0 : μA = μB = μC ;
The alternative hypothesis, takes the opposite of the null ;
H1 : μA ≠ μB ≠ μC (this means that the mean values of the treatments are not the same
The null hypothesis will

if x=2y - 1 and 2x3y + 2, then x = ?
Answer:
the value of x is 7
Step-by-step explanation:
The computation of the value of the x is given below:
Given that
x = 2y - 1...........(1)
2x = 3y + 2.................(2)
Put the equation 1 in equation 2
i.e.
2(2y - 1) = 3y + 2
4y - 2 = 3y + 2
y = 4
So,
x = 8 - 1
= 7
Hence, the value of x is 7
Sanjay surveyed 95 students at his school about their favorite class. Of the students surveyed, 19 said their favorite was Spanish. What is the experimental probability that the next student Sanjay talks to will pick Spanish?
Answer:
0.2 = 20% experimental probability that the next student Sanjay talks to will pick Spanish
Step-by-step explanation:
Probability:
A probability is the number of desired outcomes divided by the number of total outcomes.
It is called experimental when both these number of outcomes come from experiences, from a trial, as is the case in this exercise.
What is the experimental probability that the next student Sanjay talks to will pick Spanish?
19 out of 95. So
p = 19/95 = 0.2
0.2 = 20% experimental probability that the next student Sanjay talks to will pick Spanish
