Given
Olivia is growing roses and keeps track of how much fertilizer (in ounces) she adds to the soil and how many blooms each rose bush has.
She finds a linear relationship that can be modeled by the equation y = 1. 345x + 4.
The equation of the line is;
[tex]\rm y=1.345x+4\\\\[/tex]
It's bee required to compute the value of x such that the roses have 4 blooms, thus
[tex]\rm 1.345x+4=4\\\\ 1.345x=4-4\\\\1.345x=0\\\\ x=0[/tex]
Hence, Olivia only has 4 blooms when she adds no fertilizer.

The number is technically infinite, but since it's the largest multiple of 5, we can't make it infinite. So in this case, use the line method to represent the instance that it will go on, and on, and on.
The last number will end in 6, because any multidigit number with all 0's after the number, minus 4, is that number followed by 6 in the ones place.
A recipe uses 2 cups of milk to make 10 servings. If the same amount of milk is used
for each serving, how many servings can be made from three gallons?
Answers
Answer:
Correct answer (96)
Step-by-step explanation:
Answer: 240 servings
Step-by-step explanation:
If 2 cups of milk can make 10 servings, that means each cup of milk can make 5 servings.
3 gallons = 48 cups (there are 16 cups in 1 gallon)
Therefore, 3 gallons can make 48*5 servings
= 240 servings

Explanation:
Let's say 5 people get a lunch platter. The cost would be 7*5 = 35 dollars.
Or if 3 people got the lunch platter, then it would be 7*3 = 21 dollars
In general, the cost is 7p dollars where p is a placeholder for a whole number. So that's how we end up with c = 7p
If it is one platter per person, the following will be true,
Answer:
c = 7p
Step-by-step explanation:
This is because every time someone buys a platter, it adds $7 to the total cost
-> If two people buy a platter, it is 7 + 7, aka 7 *2
-> If three, it is 7 + 7 + 7 aka 7 * 3
Using this pattern, we can see that the total cost will be 7 times the number of people there.
We can put this into an equation by doing:
c = 7p

Answer:

Step-by-step explanation:
You want the solution to the equation 5(y +2/5) = -13.
SolutionThis is a 2-step equation.
Step 1, divide by 5:
y +2/5 = -13/5
Step 2, subtract 2/5
y = -13/5 -2/5 = -15/5
y = -3
Answer: y = -3
Step-by-step explanation:
[tex]\boldsymbol{\sf{Exercise\:solution \longmapsto \ 5\left(y+\dfrac{2}{5}\right)=-13 }}[/tex]
We multiply each term between kinship by 5.
[tex]\boldsymbol{\sf{5y+5\times\dfrac{2}{5}=-13 }}[/tex]
We calculate the product of rational numbers.
[tex]\boldsymbol{\sf{5y+2=-13 }}[/tex]

So, the solutions to the equation

Similarly, the solutions to the equation

b

may have without solving the equation.
When the discriminant equals less than
0
, the equation will have no solution. When the discriminant equals exactly zero, the equation will have exactly one solution. When the discriminant equals any number more than zero, there will be exactly two solutions. If the number in question that you get as a result is a perfect square in the latter case, the equation will have two rational solutions. If not, it will have two irrational solutions.
I've already shown that when you have a perfect square trinomial, you will have two identical solutions, which is equal to one solution. Hence, we can set the discriminant to

Tumbleweed, commonly found in the western United States, is the dried structure of certain plants that are blown by the wind. Kochia, a type of plant that turns into tumbleweed at the end of the summer, is a problem for farmers because it takes nutrients away from soil that would otherwise go to more beneficial plants. Scientists are concerned that kochia plants are becoming resistant to the most commonly used herbicide, glyphosate. In 2014, 19. 7 percent of 61 randomly selected kochia plants were resistant to glyphosate. In 2017, 38. 5 percent of 52 randomly selected kochia plants were resistant to glyphosate. You will conduct a significance test to determine if the data provides convincing statistical evidence, at the level of a = 0. 05, that there has been an increase in the proportion of all kochia plants that are resistant to glyphosate?
Answers
Using the z-distribution, as we are working with a proportion, it is found that since the test statistic is less than the critical value for the right-tailed test, there is not enough evidence to conclude that there has been an increase in the proportion of all kochia plants that are resistant to glyphosate.
In this problem, we consider that:
[tex]p_1[/tex] is the proportion in 2014.[tex]p_2[/tex] is the proportion is 2017.What are the hypothesis tested?At the null hypothesis, we test if there has been no increase, that is, the subtraction is of 0.
[tex]H_0: p_2 - p_1 = 0[/tex]
At the alternative hypothesis, we test if there has been an increase, hence:
[tex]H_1: p_2 - p_1 \neq 0[/tex].
What is the distribution of the difference of sample proportions?The proportions and standard errors are given by:
[tex]p_1 = 0.197, s_1 = \sqrt{\frac{0.197(0.803)}{61}} = 0.0509[/tex]
[tex]p_2 = 0.385, s_2 = \sqrt{\frac{0.385(0.615)}{52}} = 0.0675[/tex]
Hence, the distribution has mean and standard error given by:
[tex]\overline{p} = p_2 - p_1 = 0.0675 - 0.0509 = 0.0166[/tex]
[tex]s = \sqrt{s_1^2 + s_2^2} = \sqrt{0.0509^2 + 0.0675^2} = 0.0845[/tex]
What is the test statistic?It is given by:
[tex]z = \frac{\overline{p} - p}{s}[/tex]
In which p = 0 is the value tested at the null hypothesis, hence:
[tex]z = \frac{0.0166}{0.0845}[/tex]
[tex]z = 0.2[/tex]
What is the decision?Considering a right-tailed test, as we are testing if the proportion is greater than a value, with a significance level of 0.05, the critical value is of [tex]z^{\ast} = 1.645[/tex]
Since the test statistic is less than the critical value for the right-tailed test, there is not enough evidence to conclude that there has been an increase in the proportion of all kochia plants that are resistant to glyphosate.

SHOW WORK PLEASE
Answers
The degree measure of the arc is the central angle of the circle
The degree measure of the arc is 90 degrees
How to calculate the degree measure of the arcThe area (a) of the sector is 36π and the area (A) of the circle is 144π.
The area of a sector is calculated as:
[tex]a = \frac{\theta}{360} * A[/tex]
So, we have:
[tex]36\pi = \frac{\theta}{360} * 144\pi[/tex]
Divide both sides by [tex]36\pi[/tex]
[tex]1 = \frac{\theta}{360} * 4[/tex]
Evaluate the product
[tex]1 = \frac{\theta}{90}[/tex]
Solve for [tex]\theta[/tex]
[tex]\theta = 90[/tex]
Hence, the degree measure of the arc is 90 degrees

Answers
Step-by-step explanation:
The computation of the maximum allowable recurring debt is shown below:
Given ratio = 28:36
And the monthly income is $3,200
So the maximum expense on housing = 28% of $3,200 = $896
And, the maximum expense on total debt = 36% of $3,200 = $1,152
Now the maximum alloweable recurring debt is
= $1,152 - $896
