<span>A histogram shows the frequency of data within different ranges
</span><span>A dot plot is generally used with the exact data values listed along an axis and a dot for each data value above the axis. Then the exact data values can be read from the dot plot. </span>

A Dot Plot is a graph where you plot information using dots basically, and a Histogram is <span>a diagram consisting of rectangles whose area is proportional to the frequency of a variable and whose width is equal to the class interval.</span>

I need help on this
Slav-nsk [51]

Based in the given figure, we are being asked to solve the area and the perimeter of the semicircle. As we evaluate the problem, we can get a radius measurement from the rectangle. Hence, the radius is half of 4 inches which is 2 inches and since we know the formula for solving the area of a circle which is Area = pi*r², dividing the result by two, we able to get the area of the half of a circle which is equivalent to the area of the semicircle. 
Area of circle = pi*r²
Area of circle = 3.14*(2)² = 12.56
Therefore, area of semicircle is = (1/2) 12.56
Area of semicircle = 6.28 inches²

Solving for the perimeter:
Semicircle Perimeter = 1/2 * pi* d+d where d is the diameter (diameter = 4 inches)
Semicircle Perimeter = 1/2 * 3.14*4+4
Semicircle Perimeter = 10.28 inches

ALGEBRAIC model that represents the following situation: "A local fair charges an entrance fee of $5, and costs $1.25 per ride.
Sergeu [11.5K]

Answer:

y = 1.25x + 5

Step-by-step explanation:

The entrance fee is fixed, meaning it does not change. It is $5 for any person that wants to enter.

y = mx + b

only rates that change is dependent on how many rides you go on.

so 1.25 is your slope, m

y = the amount you will spend

x = the amount of rides you go on

b = the cost to enter the fair -- this is fixed.

put the equation together

May anyone help me with this please

Answer:

x = - 8, x = - 4

Step-by-step explanation:

Given

x² + 15x + 30 = 3x - 2 ( subtract 3x - 2 from both sides )

x² + 12x + 32 = 0 ← in standard form

Consider the factors of the constant term (+ 32) which sum to give the coefficient of the x- term (+ 12)

The factors are + 8 and + 4 , since

8 × 4 = + 32 and 8 + 4 = + 12 , then

(x + 8)(x + 4) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 8 = 0 ⇒ x = - 8

x + 4 = 0 ⇒ x = - 4
