Answer:
a study of the popularity of a particular music genre, with a small standard deviation about the mean
a study with a significantly larger than expected standard deviation about the sample mean
Step-by-step explanation:
Answer:
support: 25%*100 > 10%*50
refute: 25%*50 < 10%*200
Step-by-step explanation:
0.25*100=25 > 0.10*50=5
0.25*50=12.5 < 0.10*200=20
90ft by 7ft gives an area of:
90 x 7 = 630 sq ft
1/2 fl oz is needed for each square foot
630 x 1/2 = 315 fl oz required.
Answer: The answer is 9 3/4.
Step-by-step explanation: When converting an improper fraction to a mixed number, the first step to take is figure out how many times the denominator goes into the numerator. The number 4 goes into 39
9 times(4 x 9 = 36). The remainder 3 becomes the numerator of the denominator 4, therefore 39/4 converted to a mixed number is 9 3/4.
Given that 2 similar signs have a scale factor of 5:3 and the larger sign is 45 ft, then the smaller sign will have the height given by:
scale factor=(height of large sign )/(height of smaller sign)
let the height of smaller sign be x, plugging in the values we get:
5/3=45/x
solving for x we get
3/5=x/45
hence
x=3/5×45
x=27 ft
The height of smaller sign will be 27 ft
