Answer:

[tex]Cost = 21.0j[/tex] --- PRINT IT

[tex]Cost = 45.0 +18.0j[/tex] --- TOP PRINT

Step-by-step explanation:

Given

Print IT & Top Print

Represent the number of jerseys with j.

For PRINT IT.

[tex]Cost=\$21.0[/tex] per jersey

For Top Print

[tex]Base\ Amount = \$45.0[/tex]

[tex]Cost = \$18.0[/tex] per jersey.

j jerseys with PRINT IT will cost: [tex]21.0 * j[/tex]

[tex]Cost = 21.0 * j[/tex]

[tex]Cost = 21.0j[/tex]

j jerseys with TOP PRINT will cost: [tex]45.0 +18.0 * j[/tex]

[tex]Cost = 45.0 +18.0j[/tex]

Answer: 2

To maximize the length of the third side, which I'll call x, it needs to be one of the two shorter sides.

So by the triangle inequality theorem, 11+x>12 meaning the minimum whole number value of x is 2.

The revenue of US theme parks in 2012 is 14.5 in dollars.

Scatter plots are used to observe and plot relationships between two numeric variables graphically with the help of dots. The dots in a scatter plot shows the values of individual data points.

From the given table, (1990, 5.7), (1992, 6.5), (1994, 7.0), (1996, 7.9), (1998, 8.7), (2000, 9.6), (2002, 9.9), (2004, 10.8), (2006, 11.5).

Using the coordinates (1990, 5.7) and (1992, 6.5), we get

Slope m=(6.5-5.7)/(1992-1990)

= 0.8/2

= 0.4

Substitute m=0.4 and (x, y)=(1990, 5.7) in y=mx+c, we get

5.7=0.4×1990+c

c=5.7-796

c=790.3

Substitute m=0.4 and c=-790.3 in y=mx+c, we get

y=0.4x-790.3

Substitute x=2012, we get

y=0.4×2012-790.3

y=804.8-790.3

y=14.5

Therefore, the revenue of US theme parks in 2012 is 14.5 in dollars.

Answer:

144cm^2

Step-by-step explanation:

0.5x8x6x2=48cm^2

Answer:

34.78

Step-by-step explanation:

using cosine rule

AB^2 = CB^2 + AC^2 -2(CB × AC × COS C)

18^2 = 17^2 + 27^2 -2(27×17×COS C)

324= 289+729- 918COSC

324-289-789= -918COSC

-754= -918COSC

COS C = 754/918

COS C = 0.82135076253

C= arccos(0.82135076253)

C= 34.78(2 dp)

Using the Central Limit Theorem, it is found that the sampling distribution will be approximately normal, with mean of -0.04 and standard error of 0.0423.

In this problem, for each sample, the mean and the standard error are given by:

[tex]p_C = 0.08, s_C = \sqrt{\frac{0.08(0.92)}{100}} = 0.0271[/tex]

[tex]p_A = 0.12, s_A = \sqrt{\frac{0.12(0.88)}{100}} = 0.0325[/tex]

Then, for the distribution of differences, we have that:

[tex]p = p_C - p_A = 0.08 - 0.12 = -0.04[/tex]

[tex]s = \sqrt{s_C^2 + s_A^2} = \sqrt{0.0271^2 + 0.0325^2} = 0.0423[/tex]

The sampling distribution will be approximately normal, with mean of -0.04 and standard error of 0.0423.

If the price of an item is $20.00 with a sales tax of 4%, the total cost of the item is $20.80.

The total cost involves adding the price and the sales tax amount.

We can compute the total cost by determining the sales tax factor using the sales tax rate as follows:

The price of the item = $20.00

Sales tax = 4% = 0.04 (4/100)

The sales tax factor = 1.04 (1 + 0.04)

Thus, the total cost, including the price and the sales tax, is $20.80 ($20 x 1.04).

Answer:

a) This is not a random sample

b) The generalization from this sample would not be valid

Step-by-step explanation:

No the sample is not random. If the questionnaire would had been send to any five students in a class irrespective of whether they are among the top five, then the sample could be referred as random sample.

The marks of top five students in any grade would give an average value that will be an outlier to the average of marks of all students with in a grade.

Hence, the generalization from this sample would not be valid

8 miles in 1/6 hour  8*6=48 mph

10 miles in 1/5 hour   10*5=50 mph

6 miles in 1/7 hour 6*7 = 42 mph

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

Blue tripp:

Hikes 2/3 miles every 1/2 hour

Yellow troop:

Hikes 3/4 miles every 1/3 hour

How long does it take each troop to walk 1 1/2 miles, 1/2 mile, and 3/4 mile?

To hike 1 1/2 miles

Blue troop:

2/3 miles = 1/2 hours

3/2 miles = x

2/3x = 3/4

x = 3/4 * 3/2

x = 9/8 = 1 1/8 hours

Yellow troop:

3/4 = 1/3 hours

3/2 = x

3/4x = 3/6

x = 3/6 * 4/3

x = 12/18 = 2/3 hours

To hike 1/2 mile :

Blue troop:

2/3 miles = 1/2 hours

1/2 miles = x

2/3x = 1/4

x = 1/4 * 3/2

x = 3/8 hours

Yellow troop:

3/4 = 1/3 hours

1/2 = x

3/4x = 1/6

x = 1/6 * 4/3

x = 4/18 = 2/9 hours

To hike 3/4 miles :

Blue troop:

2/3 miles = 1/2 hours

3/4 miles = x

2/3x = 3/8

x = 3/8 * 3/2

x = 9/16 hours

Yellow troop:

3/4 = 1/3 hours

3/4 = x

3/4x = 3/12

x = 1/4 * 4/3

x = 4/12

x = 1/3 hours

Answer:

The y-intercept of the equation is 50

Its interpretation in the context is " the initial charge for the rental "

Step-by-step explanation:

The linear relationship can be represented by the equation

y = a x + b, where

∵ Serenity is moving and must rent a truck

∵ There is an initial charge for the rental

∴ b represents the initial charge for the rental

∵ There is a fee per mile driven

∴ a represents the fee per mile driven

∵ The equation represents this situation is C = 50 + 2.75 m

∵ C is the total cost

∵ m is the number of miles driven

→ Compare it with the form of the equation above

∴ a = 2.75

∴ b = 50

∵ b is the y-intercept

∴ The y-intercept of the equation is 50

∵ b represents the initial charge for the rental

∴ The initial charge for the rental is $50

∴ Its interpretation in the context is " the initial charge for the rental "

You're going to multiply 3 by 2 which gives you 6. you then have 6 over 2. Next find a number that goes into both of them which is 2 in this case. So now you divide the top and bottom by 2, so now you have 3 because two divided by two is zero, that is as small as it gets.
