Answer:
Domain ={0,infinity)
Range = (-infinity, 4]
Step-by-step explanation:
Given a graph with curve which has y intercept 4.
It passes x axis at 4 and extends fully
The domain is the set of values x can take
In the graph horizontal axis is x axis.
Hence from the graph we see that x can take values from 4 including 4 upto infinity.
Hence domain is x>=4
For range, we consider the values of y as per graph.
WE find that y is not taking values >4
Hence Range = (-infty, 4]
Answer:
[tex]Domain=[0,\infty)[/tex]
[tex]Range=(-\infty,4][/tex]
Step-by-step explanation:
We need to find the domain and range of the function.
Domain : It is the set of input values or x values. In a graph, domain of the function represented by the x-axis.
Range : It is the set of output values or y values. In a graph, range of the function represented by the y-axis.
From the given graph it is clear that it is defined for [tex]0\le x<\infty[/tex] and [tex]-\infty <y\le 4[/tex].
We have closed circle at (0,4). It means, 0 is included in the domain and 4 is included in the range.
[tex]Domain=[0,\infty)[/tex]
[tex]Range=(-\infty,4][/tex]
Therefore, [tex]Domain=[0,\infty)[/tex] and [tex]Range=(-\infty,4][/tex].

Find the equation of the line in slope-intercept form.Slope is 2/3 through (3, 4)
Answers
Answer:
y = (2/3)x + 2
Step-by-step explanation:
Start with the general slope-intercept form y = mx + b. Substitute 3 for x and 4 for y and 2/3 for m, and find the intercept, b:
4 = (2/3)(3) + b, or 2 = b. Then the desired equation is y = (2/3)x + 2.

There are 15 cats ready for new homes at the pet store. There are 5 cages with cats in the store. If each cage has the same number of cats, how many cats are in each cage?
Answers
There are 3 cats in each cage. They way you get this answer is by dividing the total amount of cats (15) by the total amount of cages (5). hope this helps
We find that there are 3 cats in each cage.
To find out how many cats are in each cage, we need to divide the total number of cats by the number of cages. There are 15 cats ready for new homes and 5 cages. If each cage has the same number of cats, we perform the following calculation:
Count the total number of cats: 15 cats.
Count the total number of cages: 5 cages.
Divide the total number of cats by the number of cages: 15 cats / 5 cages = 3 cats per cage.
Therefore, there are 3 cats in each cage.

Answer:
2 mugs.
Step-by-step explanation:
We have been given that Ron made [tex]\frac{2}{3}[/tex] of a quart of hot chocolate. Each mug holds [tex]\frac{1}{3}[/tex] of a quart.
To find the number of mugs that can be filled by [tex]\frac{2}{3}[/tex] quart of hot chocolate, we will divide [tex]\frac{2}{3}[/tex] by [tex]\frac{1}{3}[/tex] as:
[tex]\frac{2}{3}\div\frac{1}{3}[/tex]
Now, we will convert the division problem to multiplication problem by flipping the 2nd fraction as:
[tex]\frac{2}{3}\times\frac{3}{1}[/tex]
[tex]\frac{2\times 3}{3\times 1}[/tex]
[tex]\frac{2\times1}{1\times 1}[/tex]

Answers
domain represents the x-values. the x-values start at 1 and end at 9. 1 is included and 9 is included (otherwise an open dot would be shown).
1 ≤ x ≤ 9
because as you can see on the graph the line starts at X cordinate 1 and ends at 9. so we can say 1<x<9. then we are going to have to add an equall sign because the line includes 1 and 9. so it will be like this---1 ≤ x ≤ 9.

Determine the numbers of zeros of the polynomial function
g(x) = x^4-x^5
___ zero(s)
Answers
Factor out x^4 for find zeros:
g(x) = x^4 (1-x)
From this, we can see that if x = 0 or 1, it would cause g to result in 0.
So the zeros are 0 and 1.
The polynomial function g(x) = [tex]x^4 - x^5[/tex] has two zeroes, which are x = 0 and x = 1. This result is obtained by setting the polynomial equal to zero and solving for x.
Explanation:The given polynomial function is g(x) = [tex]x^4 - x^5[/tex]. To find the zeroes of the polynomial, this function should equal zero. Thus, we have[tex]x^4 - x^5[/tex] = 0.
We can simplify this function by factoring out the common factor, which is [tex]x^4[/tex]. The function thus becomes [tex]x^4[/tex](1 - x) = 0.
A product equals zero when one (or more) of the factors is zero. So, we need to set each factor to zero and solve for x. Setting [tex]x^4[/tex]= 0, yields x = 0. Setting (1 - x) = 0 results in x = 1.
This process gives two values of x that satisfy the equation [tex]x^4[/tex](1 - x) = 0 and therefore, the polynomial function g(x) has two zeroes, specifically x = 0 and x = 1.

Answers
Answer: The mean of the data is 433.75, variance of the data is 99667.19 and the standard deviation of the data is 315.7011.
Explanation:
The given data is 900, 35, 500 and 300.
The number of observation is 4.
Formula of mean is,
[tex]\text{Mean}=\frac{\text{Sum of observations}}{\text{Number of observations}}[/tex]
[tex]\bar{X}=\frac{900+35+50+300}{4} =433.75[/tex]
The formula of variance is given below,
[tex]\sigma^2=\frac{1}{n}\sum{(X-\bar{X})^2}[/tex]
[tex]\sigma^2=\frac{398668.75}{4}[/tex]
[tex]\sigma^2=99667.19[/tex]
The variance of the data is 99667.19
[tex]\sigma=\sqrt{99667.19}[/tex]
[tex]\sigma=315.7011[/tex]
The standard deviation of the data is 315.7011.
The other information or values of given chart is shown in the attached table.
Answer:
i. mean of the data is 402.5
ii. variance of the data is 77556.25
iii. standard deviation of the data is 278.49
Step-by-step explanation: (x - ⁻x)²
from the chart given to me, the observation are: 45, 340, 400, 825
i. mean is the summation of the observation divided by number of observation. ∈x÷n =( 45 + 340 + 400 + 825)÷ 4 = 402.5
ii. variance is the square of the difference between the observation and mean divided by the number of observation.
variance = (45-402.5)²+(340-402.5)²+(400-402.5)²+(825-402.5)²÷4=77556.5
