Answer:
A) Predicted value: 13.1 Residual: 0.9
Step-by-step explanation:
By definition:
residual = observed - predicted
The linear model is:
f(x) = 1.3x + 9.2
where f(x) is the height and x is the age of the tree.
Replacing with x = 3:
f(x) = 1.3(3) + 9.2 = 13.1 ft
which is the predicted value. The observed value is 14 ft, then:
residual = 14 - 13.1 = 0.9 ft

What is the experimental probability of rolling a number less than 3?
Answer:
The probability of rolling a number less than 3 (so, 1 or 2) is 2 out of 6, or 1/3. The odds are 4 to 2 against, or 2 to 1 against.
Step-by-step explanation:
If so, there are two numbers less than 3: 1 and 2. There are 6 total possible results, so the probability of rolling a number less than 3 is 26 or 13 or 0.3333
Select the solution for the system of linear equations y = x + 6 and y = -2x.

How many twelfths equal two fourths
Answer: 6
Step-by-step explanation: Let n represent the number of twelfths in 5/4. Expressed symbolically, this is n/12 = 2/4. The LCD is 12. Multiply numerator and denominator of 2/4 by 3, obtaining: n/12 = 6/12 then n = 6. There are 6 twelves in 2/4.
There are 6 twelfths equal two fourths.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
We have to find twelfths equal two fourths
Let x represent the number of twelfths in 5/4.
So, the mathematical expression is
x/12 = 2/4.
Now, simplifying the fraction
x/ 12= 1/2
Now, multiply both side by 12
12 x/12 = 12/2
x= 6
Hence, there are 6 twelfths .

What is the next term of the geometric sequence?
7, 21, 63
First find the common ratio of this geometric sequence.
We will use [tex]r = \frac{a2 }{a1 }[/tex].
The second term is 21 and the first term is 7.
So we have [tex]\frac{21}{7}[/tex] and this reduces to [tex]\frac{3}{1}[/tex] or 3.
So, we take the last term in our geometric sequence
and multiply it by the common ratio we just found.
So we have 63 · 3 which is 189.
So the next term in this geometric sequence is 189.
Which ratio is not equivalent to the others?

Find the 44th term in the following
arithmetic sequence :
2, 3, 4, 5, ...
Answer:
45
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 2 and d = 3 - 2 = 1, thus
[tex]a_{44}[/tex] = 2 + (43 × 1) = 2 + 43 = 45
Do the points shown represent additive inverses? Explain why or why not.
A number line going from negative 5 to positive 5. Points are at negative 3 and positive 3.
Answer:
Yes.
Step-by-step explanation:
W
The additive is what you add to a number to get zero.
The negative of a number.
Example:
The additive inverse of −5 is +5, because −5 + 5 = 0
The additive inverse of +5 is −5, because +5 − 5 = 0
Additive inverses are negated numbers.
The points on the number line are additive inverses.
For a number x, the additive inverse is -x.
The first point on the number line is:
[tex]\mathbf{x = 3}[/tex]
Negate both sides
[tex]\mathbf{-x = -3}[/tex]
-3 represents the additive inverse of 3.
Hence, the points on the number line are additive inverses.

data?
OA) 65 mi. per day
OB) 73 mi. per day
OC) 82 mi. per day
OD) 94 mi. per day
Answer:73

The MEAN in math means you add all of the numbers together
60 plus 65 plus 73 plus 82 plus 85 = 365
then you divide how many numbers there are and there is 5 numbers so you divide.
365 divided by 5 equals 73

Consider the triangle shown. Triangle R P Q is shown. Angle Q R P is 40 degrees. Angle R P Q is 105 degrees. Angle P Q R is 35 degrees. Which shows the sides in order from longest to shortest? Line segment P Q, line segment R Q, line segment R P Line segment R Q, Line segment P Q, line segment P Q Line segment R Q, line segment R P, line segment P Q Line segment R P, line segment P Q, line segment R Q
Answer:
RQ, PQ and RP.
Step-by-step explanation:
Note: Options are not correct.
From the given information, in triangle RPQ
[tex]\angle QRP=40^\circ[/tex]
[tex]\angle RPQ=105^\circ[/tex]
[tex]\angle PQR=35^\circ[/tex]
In a triangle, greatest angle has longest opposite side and smallest angle has shortest opposite side
Now,
[tex]\angle RPQ>\angle QRP>\angle PQR[/tex]
[tex]RQ>QP>PR[/tex]
[tex]RQ>PQ>RP[/tex]
Therefore, the order from longest to shortest is RQ, PQ and RP.
Answer:

Answer:
y = x
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
y - (- 11) = x - (- 11), that is
y + 11 = x + 11 ( subtract 11 from both sides )
y = x ← in slope- intercept form

Caelan has $7,500 in an account that earns 3.2% interest compounded annually. If she doesn't touch the money, how much will it be worth after 5 years?
Answer:
It'll be worth approximately $8779.3 after 5 years.
Step-by-step explanation:
Since it's compounded we need to use the appropriate formula to solve this problem, which is shown below:
M = C*(1 + r)^t
Where M is the final amount, r is the interest rate and t is the time elapsed in years. Applying the data from the problem we have:
M = 7500*(1 + 0.032)^5
M = 7500*(1.032)^5
M = 8779.2971
It'll be worth approximately $8779.3 after 5 years.

(solve triangles using the law of sines)
Answer:

Step-by-step explanation:
Use the Law of Sines as follows:
[tex]\frac{sinC}{c} =\frac{sinB}{b}[/tex]
Insert the appropriate values:
[tex]\frac{sin100}{14} =\frac{sinB}{11}[/tex]
Isolate B. Multiply both sides by 11:
[tex]11*(\frac{sin100}{14} )=11*(\frac{sinB}{11})\\\\\frac{11*sin100}{14} =sinB\\\\sinB=\frac{11*sin100}{14}[/tex]
Use the inverse:
[tex]B=sin^{-1}(\frac{11*sin100}{14})[/tex]
Insert the equation into a calculator and round to the nearest degree:
[tex]B=50.7\\\\B=51[/tex]
Angle B is 51°.

Gregor is planting pea plants in his backyard. Some of the plants are tall and the rest are short. Some of the plants are yellow and the rest are green. The numbers of different plant types are in the ratio\[\text{Tall green}:\text{Tall yellow}:\text{Short green}:\text{Short yellow} = 8:5:2:1.\]If there are 1080 green plants, then how many total plants are in Gregor's yard?
Answer:
1728.
Step-by-step explanation:
It is given that The numbers of different plant types are in the ratio
Tall green:Tall yellow:Short green:Short yellow = 8:5:2:1.
Let the numbers of Tall green, Tall yellow, Short green:, Short yellow are 8x, 5x, 2x, x respectively.
Number of green plants [tex]=8x+2x=10x[/tex]
It is given that there are 1080 green plants.
[tex]10x=1080[/tex]
[tex]x=108[/tex]
Number of total plants [tex]=8x+5x+2x+x=16x[/tex]
[tex]16x=16(108)=1728[/tex]
Therefore, total plants are in Gregor's yard is 1728.
