Answer:
is the required inequality
Step-by-step explanation:
Let the number of songs = m.
The cost of downloading 1 songs = $1.29
So, the cost of downloading 'm' songs = dollars
Since, the maximum amount she can spend on downloading songs is $20.
So, we get the inequality,
Hence, the inequality representing the situation is .

Answer:
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 550
Sample size, n = 250
Alpha, α = 0.05
Population standard deviation, σ = 120
The mean GMAT score for all test takers is 550.
The researcher believes that the mean scores in the Philippines who are interested in pursuing graduate management education will be less than 550.
We design the null and the alternate hypothesis
in the following manner:
The null hypothesis states that the sample is taken from the population and have a mean score of 550, while the alternate hypothesis states the researcher's claim that the sample of Philippines does not belong to the population and have mean score less than 550.
Answer:
100 in²
Step-by-step explanation:
The area of the banner is equal to the area of the initial rectangle minus the area of the cutout triangle.
The rectangle has a height of 8 inches and width of 14 inches, so its area is:
A = (8 in) (14 in) = 112 in²
The triangle has a base of 8 inches and a height of 3 inches, so its area is:
A = ½ (8 in) (3 in) = 12 in²
So the area of the banner is 112 in² − 12 in² = 100 in².
