Say the base length is 8, and the height is 8. If you multiply it by 1/4, the new base length is 2. The formula for the area of a triangle is: A=1/2bh you take 1/2 of 2, which is 1, and you multiply by the height (8) to get 8 square units for the area. This is opposed to if you simply did the formula without multiplying by 1/4. If you avoided multiplying by 1/4, you would get A=(4)(8), which would get you 32 square inches for the area. So, in conclusion, multiplying the base by 1/4, gets you 1/4 the area.
Answer:
1,539
Step-by-step explanation:
Using Simple Random Sampling in an infinite population (this is such a large population that we do not know the exact number) we have that the sample size should be the nearest integer to
where
<em>Z= the z-score corresponding to the confidence level, in this case 90%, so Z=1.645 (this means that the area under the Normal N(0,1) between [-1.645,1.645] is 90%=0.9)
</em>
<em>p= the proportion of young urban people (ages 21 to 35 years) who go to at least 3 concerts a year= 35% = 0.35
</em>
<em>q = 1-p = 0.65
</em>
<em>e = the error proportion = 2% = 0.02
</em>
Making the calculations
So, the sample size should be 1,539 young urban people (ages 21 to 35 years)
Answer:
2
Step-by-step explanation:
Since in this case they aren't going to cut up the fruit, you find how many times 3 will go into 11 evenly. 3x3=9 which is the largest multiple of 3 that will fit into 11. 11 pieces subtract 9 pieces given to children = 2 pieces left. Hopefully this helps.
well you have to subtract (5,-11) from (3,5)
which is (2,-16)
