Answer:
ticket in Japan: 17.23 $
ticket in Switzerland: 13.26 $
Step-by-step explanation:
let the price of one movie ticket in Switzerland be Y
let the price of one movie ticket in Japan be X
then accordingly,
it is given that
3x + 2y = 78.21
and
2x +3y = 74.24
multiplying the first equation by 2 and second by 3 we get
6x + 4y = 156.42
6x + 9y = 222.72
subtracting 1st equation from second we get
5y = 66.3
y = 13.26
by putting in the value of y in equation 2 we get:
2x + 39.78 = 74.24
2x= 34.46
x= 17.23
The answer is
96%.
Explanation:
It is generally presumed that the scores are normally distributed.
1) You are given how many standard deviations from the mean Jeremy's score is. This is exactly the definition of the
z-score. Therefore z = 1.75
2) Look at a left-tail z-table in order to find the area of the normal curve on the left of your z-score (see picture attached). A = 0.9599
3) Multiply the area by 100 in order to find the
percentile:
<span>0.9599 </span>× 100 = 95.99
Therefore, 95.99% of the students scored less than Jeremy.
Hence, the answer is
96%.
Let`s say that the expression is written in the form:a * 10^k.4 * 10^3 + 4 * 10^2 = = 4 * 10 * 10^2 + 4 * 10^2 = = 40 * 10^2 + 4 * 10^2 = = 44 * 10^2 = 4.4 * 10^3.Answer:a = 4.4 and k = 3 and the expression in the scientific notation is:4.4 * 10^3.
