Answer:
The expected change in the number of electronics job in the city next year is of 140.
Step-by-step explanation:
We have these following probabilities:
20% chance it increases by 1000.
50% chance it increases by 300.
30% it decreases by 700.
Find the expected change in the number of electronics job in the city next year
We multiply each outcome by it's probability. So
E = 0.2*1000 + 0.5*300 - 0.3*700 = 140
The expected change in the number of electronics job in the city next year is of 140.
Correct question:
Beth is making a beanbag seat in the shape of a cube. Each side of the seat is 2 feet long. Beth needs to find the volume of the seat so that she can buy the correct amount of beans. Beans are sold in bags that hold 2³ feet of beans. How many bags of beans should Beth buy?
Answer:
Beth should buy 4 bags of beans.
Step-by-step explanation:
Since Beth is making a bean bag seat in the shape of a cube, we already know the bean bag seat is a cuboid.
Also, we are asked to find the volume of a cuboid, and the volume of a cuboid is given as the product of all dimensions of the cuboid.
Therefore the volume of the seat is expressed as
V = 2 * 2 * 2
V = 8
To find the number of bags she needs, we have:
Beth needs to buy 4 bags of beans
