It would seem the problem requires you compute the mean, median, and standard deviation of each of the data sets. This is nicely done using the statistics functions of your graphing calculator.
Data Set A (mean, median, standard deviation) = (29.7, 29.5, √12.71)
Data Set B (mean, median, standard deviation) = (27.95, 27, √6.1475)
1. False. Data Set B is skewed to the right.
2. TRUE. 27.95 is within 3 of 29.7.
3. False. √12.71 ≠ √6.1475
4. False. The mean of Data Set A is 29.7.
5. False. Data Set A has the higher standard deviation.
6. TRUE. 29.7 is close to 29.5.
The true statements are
• the 2nd one
• the 6th one
Answer:
Step-by-step explanation:
100% divided by 4 is 25%
25 books were 1/4 of the books total.
the other 3/4 would be 75%
they og ordered 100 books
Answer:
Step-by-step explanation:
The general rule we are going to use to multiply this out is the distributive property. Which is:
a(b+c) = ab + ac
<u>Note:</u> x * x = x^2
Now multiplying, we get:
This is the multiplied out form, answer.
a.
This is the geometric sequence: a1 = 1.5 m = 150
cm, r = 0.74
The formula now is an = a1 x r ^ n-1
Just substitute a1 = 150 cm and r = 0.74
an = 150 x (0.74) ^ n – 1
b.
The second part is:
A6 = 150 x 0.74 ^ 6-1
= 150 x 0.74 ^5
= 150 x 0.221906624
= 33.28509936 cm
The answer is 8.
8 x 3 = 24
24 + 1 = 25
Hope I helped :)
