Answer: a
Step-by-step explanation: its getting rid of water and the original is 40
$1 = 3.70 rand
$450 is the same as 450 * $1, so multiply both sides of the conversion equation above by 450.
450 * $1 = 450 * 3.70 rand
$450 = 1665 rand
Answer:
All the conditions for the chi square test of homogeneity are satisfied.
Step-by-step explanation:
The conditions for the chi square test are
1) the sample is a random sample
2) the variable under study is categorical
3) all expected value of the number of sample observations are greater or equal to 5.
A)The observations must be independent
B) for 2 categories the expected values must be at least 5
C) for the 3 categories the expected values must be at least 1 and no more than 20% may be smaller than 5
The observations given are independent that is not equally likely i.e do not have equal chances of occurrences or are not dependent on each other.
4) the overall sample must be resonably large that is greater than 50
The square root of 34 is 5.83095
Answer:
Step-by-step explanation:
We are going to apply algebra to solve for the exponential growth
we know that the expression for the exponential formula is
where
a = the amount before measuring growth or decay
= 10,000
r = growth or decay rate = 23%= 0.23
x = number of time intervals that have passed
since this problem is on the growth we are going to replace "b" with (1+r), likewise for decay (1-r)
hence the formula becomes
The expression that will give the population value is
