Answer: The value of test statistic is 2.442.
Step-by-step explanation:
Since we have given that
n = 238
Sample mean = 23.2 minutes
Standard deviation = 20.26 minutes
Hypothesis :

So, the test statistic value would be

Hence, the value of test statistic is 2.442.
By pulling out the common factors for each pair of terms, we can rewrite the original polynomial like this:
3x(2x + 1) + 10(2x + 1)
These two terms now have a common factor of (2x + 1). Seems like we should be able to do something with that information, don't you think? In fact, we can pull out this common factor and rewrite the polynomial again:
Answer:
2998 Panda's will be left in 4 years.
Step-by-step explanation:
0.5 x 4 =2
3000-2=2998
Answer:
n + n+1 + n+2 + n+3 = 230
4n = 224
n = 56 and largest number = 59

Answer:
The answer to your question is y = -2x + 11
Step-by-step explanation:
A (1, 9)
B (3, 5)
- Find the slope



m = - 2
- Find the line equation
y - y1 = m (x - x1)
y - 5 = -2(x - 3)
y - 5 = -2x + 6
y = -2x + 6 + 5
y = -2x + 11
