Answer:
y>-3
Step-by-step explanation:
Simply translate that into math symbols to get y > -3
Good way to remember how to put the greater than or less than symbols: The alligator wants food, but it always wants the greater amount of food. The alligator mouth goes to eat the bigger number.
Answer:
1. (-∞ , -10]
2. [0, ∞ )
3. [12.566, 4.242]
4. [15, 50]
5. (-∞ , 5]
6. [18, ∞)

Answer:
Step-by-step explanation:
Given that the sample mean for a random sample of 100 cars is 27.2 miles and assume the standard deviation is 2.4 miles.
H0: x bar = 25.9
Ha: x bar ≠ 25.9
(Two tailed test at 95% confidence)
Alpha =0.05
The hypothetical mean is 25.900
The actual mean is 27.200
The difference between these two values is 1.300
The 95% confidence interval of this difference:
From -3.462 to 6.062
t = 0.5417
df = 99
standard error of difference = 2.400
The two-tailed P value equals 0.5893
Since p >0.05 this difference is considered to be not statistically significant.
The domain for N is All integers where n ≥ 1
<u>Solution:</u>
According to statement a1 = 2 and r = 4. This shows that r is greater than 1.
If r is greater than 1 than it includes integers greater than 1 or equal to 1. It does not include all the real numbers because real numbers include negative numbers also.
If starting value is 2, if we put n=0, then we get 2, but if we put a negative value than we would get a number which is not a part of our sequence.
Thus the domain of n is All integers where n greater than or equal to 1
