Answer: 5 pieces
Step-by-step explanation:
It will take the orchestra 12 minutes to play one piece, and since there are 60 minutes in one hour, we have the following equation:
60/12= 5 pieces in one hour.
Answer:
In mathematics, a coefficient is a multiplicative factor in some term of a polynomial, a series, or any expression; it is usually a number, but may be any expression.
Step-by-step explanation:
Answer:
G(62.5)
Step-by-step explanation:
30/48 × x/100=62.5/2.08
to solve x
100÷48=62.5(x)
62.5(x)×30=62.5
Answer is F
Step-by-step explanation:
First, find the degrees of freedom:
df = n − 1
df = 49
To find the p-value manually, use a t-score table. Find the row corresponding to 49 degrees of freedom. Then find the α column that corresponds to a t-score of 1.421. You'll find it's between α = 0.10 (t = 1.299) and α = 0.05 (t = 1.677). Interpolating, we get an approximate p-value of 0.084. For a more accurate answer, you'll need to use a calculator.
