Answers

Answer 1

The equation of the trend line is ŷ = 0.15x - 23.21

How to determine the average rate of change of the trend line?

The points are given as:

hr =>808, 768, 655, 684, 637, 619, 613, 609, 563

w =>  93, 94, 66, 81, 86, 75, 61, 69, 55.

Using a graphing calculator, we have the following calculation summary:

Sum of X = 5956Sum of Y = 680Mean X = 661.7778Mean Y = 75.5556Sum of squares (SSX) = 50569.5556Sum of products (SP) = 7547.1111

The regression equation is represented as:

ŷ = bX + a

Where:

b = SP/SSX

b = 7547.11/50569.56

b = 0.14924

a = MY - bMX

a = 75.56 - (0.15*661.78)

a  = -23.20961

This gives

ŷ = 0.14924X - 23.20961

Approximate

ŷ = 0.15x - 23.21

Hence, the equation of the trend line is ŷ = 0.15x - 23.21

GRADES On her first four quizzes, Rachael has earned scores of 21, 24, 23, and 17 points. What score must Rachael
earn on her fifth and final quiz so that both the mean and median of her quiz scores is 21?
points

Answers

Answer:
20

Explanation:
For the mean to be 21, the total of the 5 numbers must be 21*5= 105

To find what the final quiz score must be, we need to subtract the first 4 scores from 105. 105- 21- 24- 23- 17= 20

We can check this answer by finding the median of the 5 numbers now (17,20,21,24,23). The new median is 21 which means the final quiz score must be 20!

How many terms are in this polynomial?
What is the degree of the fourth term?
What is the coefficient of the second term?
What is the degree of the polynomial?

Answers

Answer:

4 terms

Degree of the 4th term = 5

Coefficient of the 2nd term = -6

Degree of the polynomial = 11

Step-by-step explanation:

Terms of polynomials:  parts of the expression that are separated by the addition or subtraction operation.

Therefore, there are 4 terms in this polynomial.

If a term of the polynomial has more than one variable, then to calculate the degree of that term, add the powers of all the variables in the term.

Therefore, the degree of the fourth term is:

[tex]-\dfrac43x^3y^2 \implies \textsf{degree}=3+2=5[/tex]

The coefficient is the constant.  Therefore, the coefficient of the second term is -6

Degree of a polynomial:  The greatest exponent of a variable in the polynomial equation.

As some of the terms in this polynomial have more than one variable, we must first calculate the degrees of the individual terms, and then select the greatest as the degree of the polynomial equation.

[tex]-2x^9 \implies \textsf{degree}=9[/tex]

[tex]-6x^2y^6 \implies \textsf{degree}=2+6=8[/tex]

[tex]9x^7y^4 \implies \textsf{degree}=7+4=11[/tex]

[tex]-\dfrac43x^3y^2 \implies \textsf{degree}=3+2=5[/tex]

Therefore, the greatest degree is 11, so this is the degree of the polynomial.

What is SSS similarity theorem?

The SSS similarity theorem is the theorem which is used to check the two triangle are similar or not.

SSS means the side-side-side. This theorem states that if all the three sides of a triangle are proportional to the three corresponding sides of the another triangle, then the triangles are similar.

In the given image, the sides of the first triangle are 35,20 and 20. The sides of the second triangle are x, 44,44.

Here is a pattern made from sticks:
1
a) How many sticks would be in pattern number 6?
b)
How many sticks would be in pattern number n?

Answers

Answer:

  a) 32

  b) 2 +5n

Step-by-step explanation:

Given the stick patterns shown, with 7, 12, 17 sticks, you want to know (a) the number of sticks in pattern 6, and (b) the number of sticks in pattern n.

Sequence

The numbers of sticks in the patterns shown are ...

  7, 12, 17

The differences between these numbers are ...

  12 -7 = 5

  17 -12 = 5

That is, the first pattern has 7 and the common difference between patterns is 5. This indicates the sequence is arithmetic.

b) General term

The general term of an arithmetic sequence with first term a1 and common difference d is ...

  an = a1 +d(n -1)

  an = 7 +5(n -1) = 7 +5n -5

  an = 5n +2 . . . . . . sticks in pattern n

a) Sixth term

The term when n=6 is ...

  a6 = 5·6 +2 = 32 . . . . . . sticks in pattern 6

__

Additional comment

We find it easier to determine sticks in pattern 6 by first determining the formula for pattern n.

Answers

The average thickness of a chicken eggshell being 0.000356 m is written as a single digit times an integer power of 10 as: 4 × 10^{-4} (approx)

How does scientific notations work?

The number is written in the form  [tex]a \times 10^b[/tex] where we have [tex]1 \leq a < 10[/tex]

The number b shows the order, which is the most important figure for which scientific notation is used. It tells us how much order large or small a value is in powers of 10. We can for a time, ignore the value of 'a' for two comparable quantities and only compare their orders(this type of comparison is useful when difference is too big, like size of human to size of a star etc sort of comparisons).

Scientific notations have some of the profits as:

Better readability due to compact representation

Its value in terms of power of 10 is known, which helps in easy comparison of quantities differing by a large value.

We're given that:

Average thickness of a chicken eggshell = 0.000356 m

We can rewrite it as:

[tex]0.000356 = \dfrac{356}{1000000} = \dfrac{3.56}{10000}= \dfrac{3.56}{10^4} = 3.56 \times 10^{-4}[/tex]

Since we need to write it as a single digit times an integer power of 10, therefore, we get:
[tex]3.56 \times 10^{-4} \approx 4 \times 10^{-4}[/tex]

Thus, the average thickness of a chicken eggshell being 0.000356 m is written as a single digit times an integer power of 10 as: 4 × 10^{-4} (approx)

Remark

There are two ways of calculating % error. Chemistry uses one way. Most others use the second method. I have used the second method.

Measurements

L = 10 in

w = 9 in

h = 4.5 in

Estimated result

350 cubic cm

Solution

Find the volume from the measurements of the Prism

V = L * w * h

V = 10 * 9 * 4.5

V = 405 in^3

Percent Error

% error = 100 * (Calculated Value - Estimated value)/(Estimated Value)

% error = 100 * (405 - 350)/350

% error = 100 * ( 55) / 350

% error = 15.71      

% error = 15.7      (rounded)
