Step-by-step explanation:
Substitute the value x for any number, for example x=1, you substitute x for the value 1, so this is the final equation: y= -3(1)+5 and the answer you get is the value of y. Continue substituting x for any value in the graph of course and then write the answer for y which is the number you get by solving the equation. Then plot the graph with the points you got. Hope this helps, let me know if you need more help :)
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)
Move the decimal points of both 1.8 and 9.54 to the right by 2 decimal places.and then divide like normal if the # doesn't go input a point and a 0 the answer is .0.1886 hoped I made sense

Answer:
the answers for those are number 4 is 150 and 5 is 16%
Step-by-step explanation:
number 4 500 x 30= 15,000
15,000 ÷ 100= 150
number 5 80 x 100=8,000
8,000÷ 500= 16 so 16%
You need do like 25$--------100% of real price
x$---------70%
25x70=100<u>x</u>
1,750=100<u>x</u>
<u> x</u>=1750<u />divided by 100=17.5$
