Measuring your fitness level regularly is one way to find out if you're making progress. Most fitness centers have trained staff who can evaluate your body composition, muscular strength and endurance, flexibility, and cardiovascular endurance, but it can be pricey. If you don’t have access to all the toys and tools of your gym, don’t panic. You have everything you need to measure your fitness level in your own house!
This One-Mile Walking Test measures your aerobic (cardiovascular) fitness level based on how quickly you are able to walk a mile at a submaximal (moderate) exercise intensity.

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.
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

The sum of the sequence will be S = 8 / (1 – 0.2). Then the correct option is D.
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.

Answer:
B: (-6, -1)
Step-by-step explanation:
6+x/2 = 0
6+x = 0
x = -6
-5+y/2 = -3
-5 + y = -6
y = -1
Answer:
(-6,-1)
Step-by-step explanation:
We can use the midpoint formula here to find the coordinates of B . Given data :-
A(6,-5) M(0,-3)Let B be B(p , q) . Then ,
=> M = ( x₁ + x₂/2 , y₁ + y ₂ /2 )
=> (0 ,-3) = ( 6 + p/2 , -5+q/2)
On comparing=> 0 = 6 + p/2
=> 6 + p = 0
=> p = (-6)
Similarly=> -3 = -5+q/2
=> -5+q = -6
=> q = 5-6
=> q = (-1)
Hence the coordinates of B is (-6,-1) .The probability that it will snow on Sunday is 3/5. The probability that it will snow on both Sunday and Monday is 3/10. What is the probability that it will snow on Monday, if it snowed on Sunday?
Answer:
1/2
Step-by-step explanation:
Probability of snowing on both Sunday and Monday= probability that it will snow on Sunday × probability that it will snow on Monday.
(and usually means multiply the probabilities while or implies addition of the probabilities).
Let probability of snowing on Monday be P
Hence 3/10=3/5× P
Hence P=(3/10) divided by (3/5) = 1/2

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?
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

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 :
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.
