The Sureset Concrete Company produces concrete. Two ingredients in concrete are sand (costs $6 per ton) and gravel (costs $8 per

Maksim231197 [3]

Answer:

The Sureset Concrete Company

The tons of gravel and sand that should be purchased each day are:

Sand = 800 tons

Gravel = 700 tons

Step-by-step explanation:

Two ingredients for producing concrete = sand and gravel

Cost of sand per ton = $6

Cost of gravel per ton = $8

Sand and gravel = 75% of the concrete

Therefore 25% (100 - 75%) will be made up of cement and water

Tons of concrete produced each day = 2,000

Sand and gravel = 1,500 (2,000 * 75%)

Sand <= 40% of 2,000 = 800 tons

Gravel => 30% of 2,000 = 700 (1,500 - 800) tons

To minimize costs, 800 tons of gravel and 700 tons of sand should be purchased each day.

Total cost incurred daily for both sand and gravel = $10,400 (800 * $6 + 700 * $8)

Twenty-three percent of automobiles are not covered by insurance (CNN, February 23,2006). On a particular weekend, 35 automobile

Bingel [31]

Answer:

Step-by-step explanation:

Given that twenty-three percent of automobiles are not covered by insurance (CNN, February 23,2006).

considering the total number of vehicles, probability for a randomly drawn vehicle not covered by insurance = 0.23

Each vehicle can be treated as independent of the other

Hence X no of vehicles not covered by insurance is Binom with n = 35 and p - 0.23

a) the expected number of these automobiles that are not covered by insurance=E(x) =

$np = 35(0.23)\\= 8.05$

b) the variance

= $npq = 8.05(0.77) \\=6.1985$

Std dev = square root of variance = 2.4897
