Let's consider that 23.5 is 100% of rainfall.
23.5 ..... 100 %
21.2 ..... x %
Calculate x:
, which is around 90.2%.
The percent of decrease is 100 - 90.2 = 9.8 %.
Answer:
Incorrect
Step-by-step explanation:
150 students are 100%,
82 students are x%
(82*100)/150=54,67%, so that is more than half of all students
When it comes to sampling methods, random sampling is one of the most effective. The principal wants the results of his or her sample to be as fair as possible, so it is best to choose students randomly, and in a neutral environment. The mall is not a neutral environment because not all students have access to the mall, and even those who do are not guaranteed to provide accurate results. The same goes for a basketball game, and student council. Samples taken from these environments are likely to produce more bias. However, collecting a survey from every tenth student entering the school one morning is more likely to produce accurate results that are representative of the school population.
Step-by-step explanation:
-4^(-5)/ 2^(-3) =
2³/(-4)^5 =
8/(-1024) =
- 1/128 (d)
Answer:
Yes, Sally has enough money to buy 28 cans of soda.
Step-by-step explanation:
Yes, because £10 = 1000p
1000p / 28p = 35 cans
35 cans < 28 cans
So Sally has enough money for 28 cans.
