Answers
Answer:
0.000005178
Step-by-step explanation:
we test for the goodness of fit
h0; drink preferences not changed
h1: drink preferences changed
alpha = 0.05
we solve for the test statistics
the chsquare test was performed in the attachment
Chi square = (O-E)²/E
chisquare = 32.30188
degree of freedom = n -1 = 6-1 = 5
using the chi distribution function on excel i calculated the p value
CHIDIST(32.30188, 5) =
P-value = 0.000005178
pvalue is less than 0.05 so we reject null hypothesis and conclude that there is sufficient evidence that drink preferences are changed.
the chisquare calculation is in the attachment. Thank you!

Step-by-step explanation:
The absolute value is always positive This is because it gives a measure of how far a value is from zero. The value is denoted by being enclosed in vertical bars.
That is

Matilda measures the perimeter of her bedroom to determine how many feet of border she needs to go around the tops of the walls.
Two walls are each 96 inches long, and two walls are each 3 yards long. She pays $30 for border that costs $1 per foot.
What are steps that you should take to determine if Matilda bought the correct amount of border? Select all that apply.
Answers
The steps that Matilda should take to determine if she bought the correct amount of border are:
Convert yard to feetCalculate the number of feet of border she boughtCompare the number of feet of border Maltida bought to the the perimeter of the room. Did Maltida buy the correct amount of border?The first step is to convert inches to feet
1 inch = 1/12 feet
96 / 12 = 8 feet
The second step is to convert yards to feet
1 yard = 3 feet
3 x 3 = 9 feet
Now, determine the perimeter of the room: 9 + 9 + 8 + 8 = 34 inches
The fourth step is to determine the feet of border bought: $30 / $1 = 30
34 > 30 thus the border is not enough

If f(x) = x^2 and g(x) = 1/2 f(x + 3) + 6 Describe the transformation(s)
Answers
Answer:
First, let's define some transformations:
Horizontal translation:
For a function f(x) a horizontal translation of N is written as
g(x) = f(x - N)
If N is positive we have a translation to the right
if N is negative we have a translation to the left.
Vertical translation:
For a function f(x) a vertical translation of N is written as
g(x) = f(x) + N
If N is positive we have a translation up
if N is negative we have a translation down
Vertical dilation.
For a function f(x), a vertical dilation of scale factor k is written as:
g(x) = k*f(x)
Now we can see that in our problem we have:
g(x) = (1/2)*f(x + 3) + 6
Then if we start wit f(x) we have:
first we have a dilation of scale factor k = 1/2
g(x) = (1/2)*f(x)
then we have a translation of 6 units up
g(x) = (1/2)*f(x) + 6
then a translation of 3 units to the left
g(x) = (1/2)*f(x - 3) + 6

Are of a triangle is [tex]\frac{1}{2}[/tex] height times length
8*4= 32 and 32 divided by 2 is 16.
Since there are 6 triangles, multiply 16 by 6 which will give you 96.
What is the area of the figure?
Answers
Answer:
25 1/5
Step-by-step explanation:
First, do 7 1/4 times 6. This gets you to 43.5
Next, take the area of the space that is not there. 5 times 3 2/3 is 18.33333, round to 18.3. (If this is not rounded, the fraction may be slightly different).
Now, subtract 18.3 from 43.5 to get 25.2, since 18.3 space does not exist.
25.2 as a fraction is 25 1/5

the inequality below compares two rational numbers -6/18-17/27 if two numbers were plotted as values on a horizontal number line.which statement is true?
Answers
Correct question is;
The inequality below compares two rational numbers.
-6/18 > -17/27
If the two numbers were plotted as values on a horizontal number line, which statement would be true?
A) Both numbers lie to the right of 0, and −6/18 lies to the left of −17/27
B) Both numbers lie to the left of 0, and −6/18 lies to the left of −17/27
C) Both numbers lie to the right of 0, and −6/18 lies to the right of −17/27.
D) Both numbers lie to the left of 0, and −6/18 lies to the right of −17/27
Answer:
Option D
Step-by-step explanation:
In writing inequality on a number line, any number that is negative will lie to the left of zero while any number that is positive will lie to the right of zero.
Now in this case they are both negative, so they will lie to the left of zero.
Also, the number that is greater will lie to the right of the lesser number.. In this case -6/18 > -17/27. Thus, -6/18 will lie to the right of -17/27
Thus, option D is correct
