Fill in the frequency distribution below
Answers
The frequency for the given distribution of the class interval 1.00 - 1.09 is 3, which are 1.07, 1.05 and 1.07.
What is frequency?The frequency of a repeating event is its number of instances per unit of time. In some cases, it is also referred to as temporal frequency or ordinary frequency to emphasise differences with spatial and angular frequencies, respectively. One (event) per second is equal to one hertz (Hz), which is how frequency is expressed.
The period is the reciprocal of the frequency because it is the length of time for one cycle in a repeating event. For instance, the period, T—the space between beats—of a heart beating at a frequency of 120 beats per minute (2 hertz), is equal to 0.5 seconds (60 seconds divided by 120 beats).

Define prime numbers.A whole number higher than 1 whose only elements are 1 and itself is referred to as a prime number.

A moving company charges a one-time and a cost per mile for its service. The relationship between the mileage and the cost is displaying in the graph. Which equation best represents the relationship between the total cost, C, and miles traveled, m?*
Answers
This is a linear relation. For linear relations, we have the general form:
[tex]y=ax+b[/tex]Where 'a' is the slope and 'b' is the intercept.
In this problem, we have that the intercept b is 200, because that's the point where the line crosses the y-axis. For now we have something like:
[tex]C=am+200[/tex](here y is C and x is m)
To find the slope we have to use the intercept point (0, 200) and another point on the line. We can see that one of those points is (200, 500).
For a line with points (x1, y1) and (x2, y2), the slope is find like:
[tex]a=\frac{y_2-y_1}{x_2-x_1}[/tex]In this problem, the slope is:
[tex]a=\frac{500-200}{200-0}=\frac{300}{200}=\frac{3}{2}=1.5[/tex]Then, we have the equation that represents the relationship between the mileage and the cost:
[tex]C=1.5m+200[/tex]What transformations to the linear parent function, f(x) = x, give the functiong(x) = -6X? Select all that apply.A. Vertically stretch by a factor of 6.B. Horizontally stretch by a factor of 6.O C. Shift 6 units down.D. Reflect over the x-axis.
Answers
Looking at f(x) and g(x), we can see that g(x) is made by f(x) multiplied by -6.
Since the function was multiplied by a negative value, that means we had a reflection over the x-axis.
Also, if the function was multiplied by a constant value, that means we had a vertical stretch by a factor equal to the absolute value of the constant.
Therefore the correct options are A and D.

The laboratory technician can combine L of the pure acid solution with L of the 10% acid solution to get the desired concentration.A laboratory technician needs to make a 33-liter batch of a 40% acid solution. How can the laboratory technician combine a batch of an acid solution that is pure acid wi is 10% to get the desired concentration?
Answers
The laboratory technician has to combine 11 L acid solution to get the desired concentration .
What is concentration in a solution?The volume of solute that has been dissolved in a specific volume of solvent or solution is known as the concentration of a solution. A solution with a significant concentration of dissolved solute is one that is concentrated. When there is just a minimal amount of dissolved solute in a solution, it is said to be diluted. The amount of a solute, or dissolvable substance, combined with the solvent, or other substance, determines the concentration of a solution in chemistry. C = m/V, where m is the mass of the solute dissolved and V is the total volume of the solution, is the accepted formula. Among the quantitative units of concentration are molarity, molality, mass percentage, parts per thousand, parts per million, and parts per billion.
The33 L batch is 40% acid, so 33 x 0.4 = 13.2 L of pure acid in the batch.
Let P = the number of liters of pure acid required, D = the number of liters of the 10 % solution.
Then P + 0.10 x D = 13.2.
Also, P + D = 33
This equation can be solved simultaneously by substitution.
P = 33 - D
33 - D + 0.10 x D = 16.8
-D (1 - 0.10) = 13.2 - 33
-D = -19.2/ 0.9
D = -22
P = 33 - 22
= 11 L

The 28th term of the given arithmetic sequence is 219
any arithmetic sequence can be solved once we identify the aa1 term and the an term because then we have to simply find the common difference and solve further by substituting the value in the below mentioned equation.
Given the arithmetic sequence = 3,11, 19, 27
a₁ = 3
a₂ = 11
a₃ = 19
a₄ = 27
the common difference or d = a₂ - a₁
this implies d = 11 - 3 = 8
Therefore the 28th term of the given arithmetic sequence is
a₂₈ = a₁ + ( n - 1 ) d
a₂₈ = 3 + ( 28 - 1 ) 8
= 3 + 27 × 8
= 3 + 216

Step-by-step explanation:
Invasive weed species can grow quickly. One variety grows up to 1.65 ft per day. How fast in inches per minute can this weed grow?
FACTS:
the weed grows up to 1.65 feet per day
there are 12 inches in 1 foot
there are 24 hours in 1 day
First, lets figure how many inches the weed can grow in one day:
= daily growth in feet per day * inches in 1 foot
= 1.65 feet * 12 inches
= 19.8 inches a day
If the weed can grown 19.8 inches a day, and there are 24 hours in a day:
= growth in inches per day/24 hours in 1 day
=19.8/24
= 0.825 inches per hour

What is area?
The measurement that describes the size of a location on a horizontal or contour is called area. Surface area refers to the area of an extended surface or the border of a tri object, whereas the area of a horizontal region or flat area corresponds to the area of a form or planar laminate. Area can be interpreted as both the amount of substance with a specific thickness required to create a model of the shape or as the quantity of paint required to completely cover a surface in a single coat. It is the two-dimensional equivalent of the volume of a solid or the length of a curve, both of which are one-dimensional concepts (a three-dimensional concept).
