Each of three supermarket chains in the Denver area claims to have the lowest overall prices. As part of an investigative study on supermarket advertising, a local television station conducted a study by randomly selecting nine grocery items. Then, on the same day, an intern was sent to each of the three stores to purchase the nine items. From the receipts, the following data were recorded. At the 0.100 significance level, is there a difference in the mean price for the nine items between the three supermarkets?
Item Super Ralph's Lowblaws
1 $2.32 $1.25 $1.25
2 2.40 1.80 1.87
3 2.10 3.10 3.10
4 2.30 1.87 1.87
5 1.21 1.37 1.37
6 4.04 3.05 1.72
7 4.32 3.52 2.22
8 4.15 3.08 2.40
9 5.05 4.15 4.21
1. State the null hypothesis and the alternate hypothesis.
2. What is the decision rule for both?
3. What is your decision regarding the null hypothesis?
4. Is there a difference in the item means and in the store means?

Answer:

17 meters

Step-by-step explanation:

According to the Pythagorean Theorem, we can know that the right triangle's a side is Michelle to Tucker (8 meters), and the b side is Jasmine to Tucker (15 meters), and the c side is Jasmine to Michelle. The Pythagorean Theorem equation, the side length of the c side of a right triangle is the length of a side squared plus b side squared and squared root (a^2+b^2=c^2), and so 8^2+15^2=289, and 289 square root is 17, we can know that the distance between Jasmine to Michelle is 17 meters.

Step-by-step explanation:

Answer:

Pigeonhole Principle

Step-by-step explanation:

From series {1,2......2n} ; we need to select 'n + 1' integers.

Even integers series from above series = {2,4,6..........2(n-1), 2n}

Odd integers series from above series = {1,3,5........2(n-2), 2n-1}

So, we can choose only n odd integers from the series. Hence, if we choose n+1 integers, atleast one of them have to be even integer.

Answer: She had 27.2% correct.

Step-by-step explanation: To find the percent, we can divide the part and whole then multiply the quotient by 100. After that we'll need to convert the percent to a decimal. In mathematical terms, the formula will be,

[tex]\frac{part}{whole}=quotient*100[/tex]

40% will be the part and 68% will be the whole.

Step 1.

Convert 40 into a decimal by dividing it by 100.

40 ÷ 100 = 0.4

Step 2.

Multiply 0.4 by 68.

0.4 × 68 = 27.2

Hence, she had 27.2% correct.

Answer:

The temperature halfway is -5 degrees farenheit/celcious

Step-by-step explanation:

the difference is 30 degrees

30 / 2 = 15

20 - 15 = -5

-10 + 15 = -5

Answer:

no they don't because you could not use those numbers

Answer:

A. 57m   B. 130m

Step-by-step explanation:

For problem A:

87m up a cliff - 30m up a cliff = 57m up a cliff

These are all positive values

For problem B:

100m above is talking about a positive value, making this a positive number

30m below is talking about a negative value, making this number -30

0 meters represents the surface

As you can see, this is forming a number line as of which

below the surface------------------------0m-------------------------above the surface

by substitution,

-30-----------------------------------------------0-------------------------------100

therefore, 100 - -30 = 130 meters

Answer:

3m+3p

Step-by-step explanation:

Sum of m and p is expressed as;

m + p (sum means addition)

If 3 is multiplied  by the sum, this is expressed as;

3(m+p)

Expand

3m + 3p

Hence the required expression is 3m+3p

Answer:

73.21 m

71.68°

Step-by-step explanation:

Like the question has stated, we're to solve this using Pythagoras theorem.

Pythagoras theorem states that

opp² + adj² = hyp²

From the question, we're asked to find the hypotenuse, being given the opposite side and the adjacent. The opposite side is the center of the Ferris wheel above the ground, and that is 69.5 m. While the adjacent is the distance of the second anchor.

Succinctly put, we have

69.5² + 23² = hyp²

4830.25 + 529 = hyp²

hyp² = 5359.25

hyp = √5359.25

hyp = 73.21 meters.

Therefore, the length of the cable is 73.21 meters long.

To get the angle, we use the formula

Sin Φ = opp/hyp

Sin Φ = 69.5 / 73.21

Sin Φ = 0.9493

Φ = sin^-1 0.9493

Φ = 71.68°

Therefore, the angle of elevation to the center of the Ferris wheel is 71.68°

Answer:

216 sq m

Step-by-step explanation:

Surface area of triangular prism = bh + (s1 + s2 + s3)*L

Where,

b = 6 m

h = 8 m

s1 = 10 m

s2 = 8 m

s3 = 6 m

L = 7 m

Plug in the values

Surface area = 6*8 + (10 + 8 + 6)*7

Surface Area = 48 + 24*7 = 216 m²

Answer:

3/4

Step-by-step explanation:

You can simplify it by looking for what divides into both numbers. The lowest possible number is 3 because it can go into both 9 and 12.

9/3=3

12/3=4

3/4

So we know that 3/4 is equivalent to 9/12, because 3×12=36 and 4×9=36. A simple way to look at how to check for equivalent fractions is to do what is called “cross-multiply”, which means multiple the numerator of one fraction by the denominator of the other fraction. Then do the same thing in reverse.

Answer:

So the surface area consists of 2 triangles and 3 different rectangles

Triangle area = 1/2 * 8cm * 6cm = 24cm²

Rectangle a area (bottom one) = 17cm * 8cm = 136cm²

Rectangle b area (the one to the left) = 17cm * 6cm = 102cm²

To calculate Rectangle c we need to know the hypotenuse of our triangles

Formula for the hypotenuse is c = [tex]\sqrt{a^2+b^2}[/tex]

so c = [tex]\sqrt{6^2+8^2}[/tex] = 10

Rectangle c area = 17cm * 10cm = 170cm²

So the surface area is 2 * 24cm² + 136cm² + 102cm² + 170cm² = 456cm²

The volume is 1/2 * h * a * b = 1/2 * 6cm * 8cm * 17cm = 408cm³

Answer:

[tex]\sqrt[3]{-27}[/tex]=-(3*3*3)

[tex]\sqrt[3]{-27}[/tex]=-3

-3 is a rational number, thus [tex]\sqrt[3]{-27}[/tex] will be a rational number.

Step-by-step explanation:

The above given statements can be written as decimals by first writing both quantities in a statement in the same unit.

1. $6.00 to 95 cents:

This is same as $6.00 : 95 cents = \frac{6.00}{95}956.00

Convert $6 .00 to cents to make both quantities be in the same unit.

$1 = 100 cents

$6.00 = 6*100 = 600 cents

\frac{600}{95} = 6.3295600=6.32 (to 2 d.p)

2. 3 hours to 35 minutes:

Convert 3 hours to 35 mins

1 hr = 60 mins

3 hrs = 3*60 = 180 mins

180mins : 35 mins = \frac{180}{35} = 5.14180mins:35mins=35180=5.14 (2 d.p)

3. 42 inches to 2 feet:

Convert 2 ft to inches

1 ft = 12 inches

2ft = 2*12 = 24 inches

42 in:24 in = \frac{42}{24} = 1.7542in:24in=2442=1.75
