Based on these results, express the probability that a seventh grader chosen at random will play an instrument other than drums as a percent to the nearest whole number.
Answers
Answer:
88%
Step-by-step explanation:
probability of 7th grader playing other instruments apart from drum = total number of students not playing drum / population of the 7th grade class
total number of students not playing drum = 9 + 12 + 7 = 28
population of the 7th grade class = 28 + 4 = 32
28/32 = 0.875
to express in percentage multiply by 1000 = 87.5%
To round off to the nearest whole number, look at the first number after the decimal, if it is less than 5, add zero to the units term, If it is equal or greater than 5, add 1 to the units term.

From a distance of 1217 feet from a spotlight,the angle of elevation to a cloud base is 43 degrees. Find the height of the cloud base to the cloud base to the nearest foot
Answers
Answer:
1134.9 ft
Step-by-step explanation:
CHECK THE ATTACHMENT FOR THE FIQURE
From, trigonometry,
Tan(X) = opposite/ adjacent
Distance from the spotlight = 1217 ft, which is the adjacent sides
Let the height of the cloud= X
, Which is the opposite sides
Then substitute, we have
Tan(43°)= X/1217
(0.9325)= X/1217
X= 0.9325×1217
= 1134.9 ft
Hence, the height of the cloud base to the cloud base to the nearest foot is 1134.9 ft

Step-by-step explanation:
You subtract all those distances from 22 to calculate the remaining distance.
22-4[tex]\frac{3}{4}[/tex]= 17[tex]\frac{1}{4}[/tex]
17[tex]\frac{1}{4}[/tex]-5[tex]\frac{1}{8}[/tex]=12[tex]\frac{1}{8}[/tex]
12[tex]\frac{1}{8}[/tex]-0=12[tex]\frac{1}{8}[/tex]
12[tex]\frac{1}{8}[/tex]-6[tex]\frac{1}{4}[/tex]=5[tex]\frac{7}{8}[/tex]
