Noah is growing three different types of trees. He is keeping track of the height of each tree over time.
This equation represents the height (in feet) of the Tree #1 over m months: h=3.5m
The information is in the table is for Tree #2:
time (months) height of tree (feet)
2 5
4 10
5 12.5
8 20
This graph shows how long, in months, it takes Tree #3 to grow h feet.
A graph. Height, in feet. Time, in months.
Which tree is growing the slowest?
Answers
Answer:
Tree 3
Step-by-step explanation:
The equation for the height of tree 1 is given as:
h = 3.5m
The equation for the height of tree 2 is gotten using the points from the table (2,5) and (4, 10)
Hence:
[tex]h-h_1=\frac{h_2-h_1}{m_2-m_1}(m-m_1)\\\\h-5=\frac{10-5}{4-2} (m-2)\\\\h-5=2.5m-5\\\\h=2.5m \\[/tex]
From the graph of tree 3, we get the points (2,4) and (4, 8)
Hence:
[tex]h-h_1=\frac{h_2-h_1}{m_2-m_1}(m-m_1)\\\\h-4=\frac{8-4}{4-2} (m-2)\\\\h-4=2m-4\\\\h=2m \\[/tex]
Therefore tree 3 grows the slowest

the number if baskets nikki can make varies directy with the time she spends making the baskets she can make 4 baskets in 1/2 an hour how many baskets can nikki make in 5 hours
Answers
Answer:
40 baskets
Step-by-step explanation:
Find out how many baskets she can make in an hour. Since she makes 4 in 1/2 an hour, multiply 4 by 2 to find out how much she makes in an hour. She makes 8 baskets an hour, so multiply 8 by 5. 8 x 5 = 40.
Answer:
40 Baskets
Step-by-step explanation:
4 x half an hour = 8 baskets an hour. 8 x 5 = 40
Suppose a least squares regression line is given by y= 4.302x - 3.293. What is the mean value of the response variable if x = 20?
Answers
Answer:
i think this is the answer
Step-by-step explanation:
[tex]4.302(20) - 3.293 = 82.747[/tex]
The mean value of the response variable is 82.747.
What is Regression line?Linear Regression calculates the equation of the line that is the best fit for the given data points. Linear regression models a linear relationship between the input variable x and the output variable y.
Here, given regression line;
y= 4.302x - 3.293 ...............(i)
Now, value of x is given; x = 20
Put the value of x in equation (i), we get
y = 4.302 X 20 - 3.293
y = 86.04 - 3.293
y = 82.747
Thus, the mean value of the response variable is 82.747.

1. A newspaper headline claims: "Apple spends far less on Research & Development
than any of its rivals." Further into the story, the reporter writes that Apple spends a
paltry 2% of revenues compared with 14% at Google and Microsoft.
a. What is the mistaken assumption here?
b. Why is that assumption incorrect?
c. Is there a situation where the headline is still correct?
Answers
Answer:
Step-by-step explanation:
a)
The mistaken assumption is that Apple spends "far less" on Research and Development than any of its rivals.
b)
The assumption is incorrect because it took cognizance of the percentage used, and not the actual money spent. In truth, Apple generates far more income than the other two rivals. With Apple generating over $100bn in the said time span, and Google generating $37bn. At the end of the day, Apple spends $2.1bn on Research and Development, while Google spends $5.3bn on the same. This is quite close than the quoted distance of 14% - 2%
c)
Yes, I think so. But only when the 3 companies generate almost the same revenue.
Based on the description of the headline given in the scenario, the solution to the problems posed are :
A.)
The mistake in the assumption is that, the headline focused just on the percentage of the revenue made by each company that is spent on R&D.
B.)
The assumption is incorrect because, the revenue generated by the companies aren't the same. Hence, making comparison based on the percentage alone is incorrect.
C.)
The headline may be correct only when the revenue generated by each company is the same.

For the terms and like terms just put:

Answers
Answer:
T: x^2 & 3 LT: -x & -3x
Step-by-step explanation:
x^2 has no other like term like: -x^2, 8x^2 or basically no longer "x^2"
3 is the same ^ there is no other single integer
(We cannot use -3x because it has an x attached to it)
-x & -3x are like terms because they both have an x to it a single x, not a x with an exponent like x^2
so -x + (-3x) would equal -4x if we wanted to solve it
Answer:
Terms: 3, (-x), x², (-3x)
Like terms: (-x) and (-3x)
Step-by-step explanation:
A term is a single number (positive or negative), a single variable (a letter), or several variables multiplied but not added or subtracted.
Like terms are terms that have the same variables and power like -x.

The value 1 is a solution for x^2-6x+5=0
A. True
B. False
Answers
Answer:
The complex solution would be: X = 5,1
Step-by-step explanation:
Answer:
x=1
TRUE because Factoring x2-6x+5
The first term is, x2 its coefficient is 1 .
The middle term is, -6x its coefficient is -6 .
The last term, "the constant", is +5
Step-1 : Multiply the coefficient of the first term by the constant 1 • 5 = 5
Step-2 : Find two factors of 5 whose sum equals the coefficient of the middle term, which is -6 .
-5 + -1 = -6 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -5 and -1
x2 - 5x - 1x - 5
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-5)
Add up the last 2 terms, pulling out common factors :
1 • (x-5)
Step-5 : Add up the four terms of step 4 :
(x-1) • (x-5)

• Your work solving the inequality
• The solution graphed on a number line
• The solution in set notation
• The solution in interval notation
Answers
Answer:
The required inequality is: 12 ≤ 3x < 21
Step-by-step explanation:
We are given: three times a number is greater than or equal to 12 and less than 21
We need to answer following questions:
1) The inequality translated in numerical form
Let number = x
12 ≤ 3x < 21
2) Your work solving the inequality
We need to find value of x. Divide the inequality by x
4 ≤ x < 7
3) The solution graphed on a number line
It is shown in figure attached.
4) The solution in set notation
The set notation is: Considering x belongs to natural numbers N
{∀ x|x∈N, 4 ≤ x < 7}
5) The solution in interval notation
The interval notation is: [4,7)
because we have 4 less than equal to x and x is less than 7
