Answer:
No, If a stays the same b must be a value within the interval that satisfy the inequality.
Step-by-step explanation:
An inequality provides an interval as a solution. So, actually the solution of an inequality comprises many coordinate pairs. To show that, let's show this graphically. Instead of (a, b), let's work with numbers.
Let's use as an example a -b <0
1) Suppose a=1, b=3
2) If a stays the same value, i.e. 1, then b=?
Then b>1
Answer:
yes
Step-by-step explanation:
Find the amount of the sales tax:
46 x 0.06 = 2.76
Add the sales tax to the items total:
46 + 2.76 = 48.76
50 > 48.76
Since $48.76 is less than $50 he has enough money
Answer:
it's the last one *25,000 J
Step-by-step explanation:
Answer: The z-scores for a woman 6 feet tall is 2.96 and the z-scores for a a man 5'10" tall is 0.25.
Step-by-step explanation:
Let x and y area the random variable that represents the heights of women and men.
Given : The heights of women aged 20 to 29 are approximately Normal with mean 64 inches and standard deviation 2.7 inches.
i.e.
Since ,
Then, z-score corresponds to a woman 6 feet tall (i.e. x=72 inches).
[∵ 1 foot = 12 inches , 6 feet = 6(12)=72 inches]
Men the same age have mean height 69.3 inches with standard deviation 2.8 inches.
i.e.
Then, z-score corresponds to a man 5'10" tall (i.e. y =70 inches).
[∵ 1 foot = 12 inches , 5 feet 10 inches= 5(12)+10=70 inches]
∴ The z-scores for a woman 6 feet tall is 2.96 and the z-scores for a a man 5'10" tall is 0.25.
Based on the sequence, the answer for question (a) is 3.5 which is the value of the common difference. The recursive rule for the sequence is x = n + 3.5.
2.5 + 3.5 = 6
6 + 3.5 = 9.5
9.5 + 3.5 = 13
13 + 3.5 = 16.5
16.5 + 3.5 = 20
Hope this helps.
