Answer:
Step-by-step explanation:
If x is the white dot on the graph:
From what it looks like, x is right between -35 and -34 x (which is -35.5).
If that is the case then none of the answers are correct since -35.5 is equal or less than x. (the sign looks like this: "[tex]\leq[/tex]" )
But if you have to choose one of the answers then number 4 (-35.5 < x) would be closest.

The linear factors of the given polynomial are (2x+3)(x+1)(x+2+i)(x+2-i)
What is linear factor?The linear factors of polynomials are the first-degree equations that act as the building block for the simple or complex higher-order polynomials.
Given that, a polynomial 2x⁴+13³+27x²+13x-15, the remainder upon division with x²+4x +5 is zero,
That means, x²+4x +5 is a factor of the given polynomial,
On diving 2x⁴+13³+27x²+13x-15 by x²+4x +5 we get 2x²+5x+3 as quotient that means, x²+4x +5 and 2x²+5x+3 are the factors of the polynomial,
On factorizing both the factors we get,
(2x+3)(x+1)(x+2+i)(x+2-i)
Hence, the linear factors of the given polynomial are (2x+3)(x+1)(x+2+i)(x+2-i)

Write the equation. Solve for x.
Answer:
X = 3
Step-by-step explanation:
First count the amount of X's. There are 5 and it is plus two. Both sides should be equal in value so you have to set up your equation.
5x + 2 = 17
Then Solve For X
5x + 2 = 17
Subtract 2 from both sides
5x = 15
Divide by 5
X = 3
Check your answer
5(3) +2 = 17
15 + 2 = 17
17 = 17

Suppose that 65\ee, percent of the 310{,}000310,000310, comma, 000 citizens in a county are registered to vote. A not-for-profit organization takes an SRS of 100100100 of these citizens and finds that 67\gg, percent of those sampled are registered to vote. The organization plans on taking repeated samples like this. What are the mean and standard deviation of the sampling distribution of the proportion of citizens who are registered to vote
Answer:
mean= 0.65
standard deviation=[tex]\sqrt{\frac{0.65(0.35)}{100}[/tex]
Step-by-step explanation:
The mean of the sampling distribution is 0.65 and the standard deviation is approximately 0.004779.
What is the standard deviation?The standard deviation mathematical and statistical analysis tool used to explain the diversity of treatments or values around the Mean is the standard deviation, which is also known as the square root of variance.
The mean of the sampling distribution of the proportion of citizens who are registered to vote is equal to the proportion of all citizens who are registered to vote, which is 65% = 0.65.
The standard deviation of the sampling distribution is equal to the standard error of the proportion, which can be calculated as follows:
standard error = √((65% × 35%) / 100)
= √((0.65 × 0.35) / 100)
= √(0.0227 / 100)
= √(0.0000227)
= 0.004779
Therefore, the standard deviation is approximately 0.004779.

Answer:
answer is 0
Step-by-step explanation:
someone please pass the answers to this
Answer/Step-by-step explanation:
1. The figure is composed of a triangle and a rectangle.
Area of the triangle = ½*base*height
base = 4 ft
height = 12 - 8 = 4ft
Area of triangle = ½*4*4 = 8 ft²
Area of rectangle = length * width
Length = 8 ft
Width = 4 ft
Area of rectangle = 8*4 = 32 ft²
✔️Area of the figure = 8 + 32 = 40 ft²
2. The figure is composed of a semicircle and a triangle
Area of the semicircle = ½(πr²)
radius (r) = 3 cm
π = 3
Area = ½(3*3²) = 13.5 cm²
Area of triangle = ½*base*height
base = 3*2 = 6 cm
height = 6 cm
Area = ½*6*6 = 6 cm²
✔️Area of the figure = 13.5 + 6 = 19.5 cm²

Answer:
9.6
Step-by-step explanation:
Find the diagram attached. Using the similarity theorem of triangles
AC/AD = FH/EH
Given
AC = 24
AD = 35
FH = x
EH = 14
Substitute into the formula
24/35 = x/14
Cross multiply
35×x = 24×14
35x = 336
x = 336/35
x = 9.6
Hence the value of x is 9.6
The figures are similar. Find x
Answer:
x = 15
Step-by-step explanation:
The scale factor is 8:20, we need to set up a proportion
Setting up the proportion:
[tex] \frac{8}{20} = \frac{6}{x} [/tex]

the community center built a new playground. The sections of the playground are geometric shapes, shown in the picture below
What is the total area of the surface of the entire playground in square feet (use 3.14 for pi)
Answer:
area = 2348 ft^2
Step-by-step explanation:
(15 x 40) + (28x40) + Pi(20^2)(0.5) = area
area = 600 + 1120 + 628 = 2348 ft^2
Answer:
Step-by-step explanation:
So we have a half circle, a rectangle, and a triangle.
circle area is A=3.14r^2 and the radius is 40/2=20, since we only have half a circle
A=3.14(20^2)/2=628ft^2
The rectangle has an area A=LW=28(40)=1120ft^2
The triangle has area A=bh/2=40(15)/2=300ft^2
So the total area is
A=628+1120+300=2048ft^2
