The Program for International Student Assessment (PISA) conducts test in mathematics in countries throughout the world. For 15-yer-olds in all developed countries, the scores in 2012 were normally distributed with a mean of 494 and a standard deviation of 92. If there were 5,000 students who took the test, how many would have a score larger than 586?

a
80,000
b
16
c
2,500
d
800

step-by-step explanation:

$320 to $405

step by step explanation:

in one day he earns between $64 and $81

therefore if he works for 5 days, he will earn between 64 x 5 to 81 x 5

= $320 to $405

step-by-step explanation:

consider the parallelogram shown in the attached image.

in the parallelogram hijk, the length of hk is given as,

from the properties of parallelogram we know that the opposite sides of a parallelogram are parallel to each other and are equal in measure.

therefore, the length of the side ij must be equal to the length of the side hk and that is .

hence, the expression for the length of ij confirms that hijk is a parallelogram.
