A store pay $120 for a bicycle. The store has a 60% markup policy. What is the selling price of the bicycle? (answer $192)
Use your answer from the above question to help answer this question!! The store is now going out of business and is selling all of the bicycles at a 30% discount. What is the sale price of the bicycle? (answer $134.4)

Use the information from the last two questions to help you answer this question. Will the store make money or lose money on the bicycle? How much?

Answers

Answer:

The store will make money for each option/event. For the first option, the store will earn extra $72. For the second option, the store will earn extra $14.4.

Step-by-step explanation:

120 x 1.6 = 192

192 x 0.7 = 134.4

For problem 1, the answer is $192

For problem 2, the answer is $134.4

The store will make money for each option/event.

192-120=72

134.4-120=14.4

A group of transfer bound students wondered if they will spend the same mean amount on texts and supplies each year at their four-year university as they have at their community college. They conducted a random survey of 54 students at their community college and 66 students at their local four-year university. The sample means were $947 and $1,011, respectively. The population standard deviations are known to be $254 and $87, respectively. Conduct a hypothesis test to determine if the means are statistically the same assume alpha is 0.05.

Answers

Answer:

We accept H₀. We don´t have enough evidence to support the difference between the two means

Step-by-step explanation:

Group 1 : Comunity College

Sample:

size  :   n₁  = 54

Sample mean    x₁  = 947

Sample standard deviation     s₁ = 254

Group 2 : Local University

Sample

size  :  n₂  =  66

Sample mean :  x₂  = 1011

Sample standard deviation    s₂  =  87

Significance level  α  = 0,05      α  =  5 %      CI = 95 %

Both samples are with n> 30 so we can use z table for the test

from z-table we find  z(c)  =  1,96

The problem statement establishes to run a hypothesis test to determine if the means are statistically the same  ( or different) then we use two-tail-test

Hypothesis Test

Null Hypothesis                        H₀             x₁   -  x₂  = 0 or    x₁  = x₂

Alternative hypothesis             Hₐ             x₁  -  x₂  ≠  0  or    x₁ ≠ x₂

To calculate

z(s)  =  (  x₁   -  x₂  ) / √ s₁²/n₁  + s₂²/n₂ )

z(s)  =  947  -  1011 / √  (254)²/54   +  (87)² / 66

z(s) = -  64  /√ 1194,74  +  114,68

z(s) =  - 64  / 36,185

z(s) =  - 1,77

Comparing modules of  |z(c)|  and |z(s)|

z(s) < z(c)

Then z(s) is in the acceptance region we accept H₀ . There is not enough evidence to support differences in the means of the two groups

A window is 12 feet above the ground. A ladder is placed on the ground to reach the window. If the bottom of the ladder is placed 5 feet away from the building, what is the length of the ladder?

Answers

Answers :

you will nees to use pythagorean theorem a^2 + b^2 = c^2

the a and b values will be 12 and 5 feet. So just plug them in and solve for c

12^2 + 5^2 = c^2

144 + 25 = c^2

169 = c^2 square root both sides

13 = c

so the ladder has a length of 13 feet.

What is the sum of the geometric series?

Let a be the first term and r be the common ratio. Then the sum of the geometric series will be

S = a / (1 – r) if r < 1

S = a / (r – 1) if r > 1

The sum of [tex]\rm \Sigma_{n = 1}^{\infty} 8(0.2)^{n - 1}[/tex].

Then the first term of the geometric sequence will be 8.

And the common difference between the successive terms will be 0.2.

The common ratio less than one, then the formula for the sum will be given as

S = a / (1 – r) if r < 1

Then the sum of the sequence till infinity will be

S = 8 / (1 – 0.2)

S = 8 / 0.8

S = 10

Thus, the sum of the sequence will be S = 8 / (1 – 0.2).

Then the correct option is D.

In the passage, which detail best supports the central idea?Food SafetyMany people often ask "How do I know if foods in the freezer are safe?" Every year, thousands of callers to the U.S. Department ofAgriculture (USDA) Meat and Poultry Hotline aren't sure about the safety of items stored in their own home freezers. The confusion seems tobe based on the fact that few people understand how freezing protects food. That's why it is important to educate oneself on how to freezefood safely. The more knowledge people have about their foods, the more they can protect themselves from illnesses caused by spoiled food.One thing to remember is that food stored constantly at 0 degrees Fahrenheit will always be safe. Only the quality suffers with lengthyfreezer storage. Freezing keeps food safe by slowing the movement of molecules, causing microbes to enter a dormant stage. Freezingpreserves food for extended periods. It prevents the growth of microorganisms that cause both food spoilage and foodborne illness.A way to preserve the quality of food is to pay attention to the packaging. Proper packaging helps maintain quality and prevent freezerburn. It is safe to freeze meat or poultry directly in its original packaging: however, this type of wrap is permeable to air. This may causequality to finish over time. For prolonged storage, overwrap these packages as you would any food for long-term storage. It is not necessaryto rinse meat and poultry. Freeze unopened vacuum packages as is. If you notice that a package has accidentally been torn or has openedwhile food is in the freezer, the food is still safe to use; merely overwrap or rewrap it.Because freezing keeps food safe almost indefinitely, recommended storage times are for quality only. To determine the quality, first checkfor odor. Some foods will develop a rancid or off odor when frozen too long and should be discarded. Some may not look picture perfect orbe of high enough quality to serve alone but may be edible; use them to make soups or stews. which is an example of growth and decay:f(x)=250(0.87)xf(x) = 15 (1.25)x Por favor aydeme es para hoy :( Why does the moon appear to change its shape as seen from earth?
