The city of Raleigh has 9200 registered voters. There are two candidates for city council in an upcoming election: Brown and Feliz. The day before the election, a telephone poll of 350 randomly selected registered voters was conducted. 109 said they'd vote for Brown, 235 said they'd vote for Feliz, and 6 were undecided. Give the sample statistic for the proportion of voters surveyed who said they'd vote for Brown. Note: The proportion should be a fraction or decimal, not a percent.

Yes, Jalen is correct because the rectangle has a perimeter of 20 inches with the smaller side measuring 3 inches and the longer side of the rectangle had to be 7 inches.

In Mathematics and Geometry, the perimeter of a rectangle can be calculated by using this mathematical equation (formula);

P = 2(L + W)

Where:

By substituting the given side lengths into the formula for the perimeter of a rectangle, we have the following;

P = 2(3 + 7)

20 = 2(10)

20 = 20 (True).

Therefore, Heather's account balance will be $4,042.18 after 9 years if the interest is compounded 4 times each year.

Compound interest is a method of calculating interest where the interest earned on an investment is added to the principal amount, and the interest on the new total is calculated for the next period. This process continues over time, resulting in the gradual growth of the investment.

Given by the question.

To calculate the account balance after 9 years with compounded interest, we can use the formula:

A = P \((1 + r/n) ^{nt}\)

Where:

A = the account balance after t years

P = the initial investment

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the number of years

Plugging in the given values, we get:

A = 2975 \((1+0.035/4)^{4*9}\)

A = 2975  \((1 + 0.00875)^{36}\)

A = 2975  \((1.00875) ^{36}\)

A = 2975(1.358016)

A = 4042.18

Answer:

0.74

Step-by-step explanation:

P(not E) = 1 - P(E) = 1 - 0.26 = 0.74

Consequently, there are 5 elements in A B'.

Given the following definitions:

U = {1, 2, 3, 4, 5, 6, 7}A = {1, 2, 4, 5}B = {1, 3, 5, 7}

The complement of a set B is the set of all elements that belong to the universal set U but not to B.

A’ = {x | x ∈ U and x ∉ A} = {3, 6, 7}B’ = {x | x ∈ U and x ∉ B} = {2, 4, 6}

The union of sets A and B is the set of all elements that belong to set A or set B, or both.

A ∪ B = {x | x ∈ A or x ∈ B}

= {1, 2, 3, 4, 5, 7}A ∪ B'

= {x | x ∈ A or x ∈ B’}

= {1, 2, 4, 5, 6}

Explanation:

The correct answer is option D maximum occurs at the function's y-intercept.

A quadratic function's graph is a parabola, which, depending on the sign of the coefficient a, might expand upward or downward. A quadratic function's primary traits are:

The greatest or minimum point of the function is at the parabola's vertex.

The vertex serves as the point on the vertical axis of symmetry.

The function's value at x = 0 is known as the y-intercept.

The x-intercepts of the parabola, which appear where the function equals 0, are the roots or zeros of the function.

We must examine the layout of the quadratic function g's graph, which is depicted in the table, in order to ascertain its properties. The chart shows that the parabola's vertex, or maximum/minimum point, is at:

x = -2, where g(-2) = -16.

The y-intercept also happens to be at g(0) = 4.

The solution to the system of equations is x = 1 and y = -3.

To solve the system of equations using the substitution or elimination method, let's start with the substitution method.

Given equations:

y = 4x - 7

4x + 2y = -2

We'll solve equation 1) for y and substitute it into equation 2):

Substituting y from equation 1) into equation 2):

4x + 2(4x - 7) = -2

4x + 8x - 14 = -2

12x - 14 = -2

Now, we'll solve this equation for x:

12x = -2 + 14

12x = 12

x = 12/12

x = 1

Now that we have the value of x, we can substitute it back into equation 1) to find y:

y = 4(1) - 7

First of all, the angle that is formed in a full rotation is 2π.

The area of a circle is given by the formula; A = πr²

The central angle is given by the angle symbol θ. Thus, we have to multiply the area of the circle by a factor θ/2π

Answer:

\(x=30\\y=68\\z=82\)

Step-by-step explanation:

x = measure of the first angle

y = measure of the second angle

z = measure of the third angle

The sum of the measures of the second and third (y+z) is five times the measure of the first angle (=5x)

\(y+z=5x\)

The third angle is 14 more than the second

\(z=y+14\)

And remember that the sum of these three angles must be equal to 180.

\(x+y+z=180\)

Let's take these equations

\(y+z=5x\\z=y+14\\x+y+z=180\)

If you take a look at the first equation, we have y+z = 5x and we have y+z in the third equation as well, we can replace that....

\(x+y+z=180\\x+(y+z)=180\\x+(5x)=180\)

Distribute the + sign

\(x+5x=180\)

Combine like terms;

\(6x=180\)

Divide by 6.

\(x=\frac{180}{6}\\ x=30\)

We have now defined that the measure of the first angle is 30º.

Let's take another equation... for example \(z=y+14\)

I'm going to take this one because if I replace x and z in the third equation, all I'll have left will be y.

\(x+y+z=180\\30+y+(y+14)=180\)

Distribute the + sign and Combine like terms;

\(30+y+y+14=180\\44+2y=180\\\)

Subtract 44 to isolate 2y.

\(2y=180-44\\2y=136\)

Now divide by 2.

\(y=\frac{136}{2}\\ y=68\)

We already have the value of x and y. Once again, replacing this in the third equation will leave us with z to solve for.

\(x+y+z=180\\30+68+z=180\\98+z=180\\z=180-98\\z=82\)
