0.15
0.25
0.65
The correct answer is option C which is the ratio of the difference in the means of the two teams to the mean absolute deviation of Team B will be 0.25.
What is mean?Mean is defined as the ratio of the sum of the number of the data sets to the total number of the data.
The difference between the mean times is about 16 times the mean absolute deviation of the data set.
59.32 - 59.1 = 0.22
2.4 - 1.5 = 0.9
0.22 / 0.9 = 0.25
Therefore the correct answer is option C which is the ratio of the difference in the means of the two teams to the mean absolute deviation of Team B will be 0.25.

Step-by-step explanation:
The weight of a bag of Brand A cookies is labeled as 3 ounces on the bag. However, the actual weights of the bags vary by a small amount. According to the packaging specifications, the weights are approximately normally distributed with a mean of 3.05 ounces and a standard deviation of 0.06 ounce. Select the number to complete the sentence. According to the specifications, approximately percent of the bags weigh 3.00 ounces or more
Using the normal distribution, it is found that approximately 79.67% of the bags weigh 3.00 ounces or more.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.The mean and the standard deviation are given, respectively, by:
[tex]\mu = 3.05, \sigma = 0.06[/tex]
The proportion of the bags that weigh 3.00 ounces or more is one subtracted by the p-value of Z when X = 3, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{3 - 3.05}{0.06}[/tex]
Z = -0.83
Z = -0.83 has a p-value of 0.2033.
1 - 0.2033 = 0.7967 = 79.67%.
79.67% of the bags weigh 3.00 ounces or more.

Find the common denominator needed to subtract the following fractions. 5/6 -2/7 =
Answer:
42
Step-by-step explanation:
We need to find the Least Common Multiple (that isn't 0) between 6 and 7. To do this, list each number's multiples.
Multiples of 6: 0, 6, 12, 18, 24, 30, 36, 42, 48, 54
Multiples of 7: 0, 7, 14, 21, 28, 35, 42, 49, 56, 63
Their LCM is 42. Now, we multiply the fractions so the denominators are both 42. !You have to multiply both the numerator and denominator by the same number! For 6, 6*7 is 42, so you multiply both 6 and 5 by 7. When you do this, you get 35/42. For 7, 7*6 is 42, so you have to multiply both 7 and 2 by 6. When you do this, you get 12/42. The new problem is 35/42-12/42.
Hope this helps!

Which of the following steps were applied to ABCD to obtain A'B'C'D'?
A. shifted 4 units left and 3 units up
B. shifted 3 units left and 3 units up
C. shifted 4 units left and 4 units up
D. shifted 3 units left and 4 units up
Answer:
A
Step-by-step explanation:
To find the transformation, we need to take a point and the point to which it has been translated.
Let's take A and A'.
⇒ A = (2, -2)
⇒ A' = (-2, 1)
Change in x : -4 (shifted 4 units left)
Change in y : 3 (shifted 3 units up)
This means to obtain A'B'C'D' from ABCD, the graph has to be :
shifted 4 units left and 3 units up

Solve the inequality.
-3(4n+1) < -6(2n-6)
Answer:
no solution
Step-by-step explanation:
Given :
-3(4n+1) < -6(2n-6)
Divide by -3 on each side (and remember to change the sign) :
-1/3 x -3(4n+1) < -1/3 x -6(2n-6)
4n + 1 > 2(2n - 6)
Expand the RHS :
4n + 1 > 2(2n) - 2(6)
4n + 1 > 4n - 12
Solution :
As the coefficient of x is the same on both sides, and the constants are different, this inequality has no solution
Answer:
Given inequality:
-3(4n + 1) < -6(2n - 6)
Expand the brackets:
⇒ -12n - 3 < -12n + 36
Add 12n to both sides:
⇒ -12n - 3 + 12n < -12n + 36 + 12n
⇒ -3 < 36

WILL MARK BRAINLIEDT If the length of an arc of a circle of radius 7 is approximately 10.99 cm. What is the measure of the central angle associated with the arc? Use 3.14 for π. Give your answer in degrees and radians (approximate to two decimals and exact).
The angle that defines the arc is 1.57 radians or 90°.
How to get the angle of the arc?For a circle of radius R, the length of an arc defined by an angle θ in radians is given by:
L = θ*R.
Here we know that the radius is R = 7cm, and the length of the arc is 10.99 cm. Replacing these in the above equation:
10.99 cm = θ*7cm
θ = (10.99 cm/7 cm) = 1.57
Then the angle is 1.57 radians. Remember that:
3.14 radians = 180°
Then:
θ = (1.57/3.14)*180° = 90°

Describe a situation in your life when what you know about probability may have helped you make a decision. How could you have used probability to help you with your decision? Generally, in what types of situations would knowledge of probability prove useful? Why?
Answer:
Knowledge > Probability
Step-by-step explanation:
In the moment knowledge would be useful because you are thinking about the decision you are making but after days, months or years probability would be in your mind. Also probability is just another word for chance so there would be no confirmation of said thing happening but when you have knowledge your brain knows that said thing is 100% going to happen, so for me personally knowledge is more useful than probability
