Answer:
The answer is 300,000.
Step-by-step explanation:
Hundred thousand would be one hundred (100) and a thousand, which is three zeroes. So we put three zeroes after 100 and we get 100,000. So in this case we're rounding to 300,000.
Answer: a. 7
Step-by-step explanation: <u>Degrees</u> <u>of</u> <u>Freedom</u> is the number of values "allowed" to vary. For example:
In the experiment above, the sample has 8 tobacco leaves. Two strains will be applied to each leaf. The decision of which strain goes to the right or left is random. Each strain have 7 possible leaves it can be applied, because, for the last, the eight leaf, there is no choice.
Therefore, the degrees of freedom for this experiment is 7.
It can also be calculated as
df = n - 1
df = 8 - 1
df = 7

Step-by-step explanation:
Answer:
19 weeks
Step-by-step explanation:
Given equation:
P = w
Where,
w = the number of weeks he has taken piano lessons
p = the total number of pieces he has learned
how many weeks of piano lessons will Lamar need before he will be able to play a total of 19 pieces?
Find w when p = 19
P = w
p = 19
Since P = w
19 = w
Therefore,
w = 19
Lamar need 19 weeks before he will be able to play a total of 19 pieces
Two integers are 26 and 28
Step-by-step explanation:
- Step 1: Let the two consecutive positive integers be x and x + 2. Product = 728
x(x + 2) = 728
x² + 2x - 728 = 0
x = -2 ±√4 - 4 × 1 × -728/2 (using quadratic formula)
= -2 ±√4 + 2912/2
= -2 ±√2916/2 = -2 ± 54/2
= -56/2, 52/2
= -28, 26 (negative value is neglected)
∴ x = 26
x + 2 = 28
