Evaluate, 2 x {[5 x (60-14 divided by 7)] + 25} x 5=?

1 answer:

8 0

$2 * \left \{ [5 * (60-\frac{14 }{7} )] + 25 \right \} * 5=2 * \left \{ [5 * (60-2)] + 25 \right \} * 5= 2 * \left \{ (5 * 58) + 25 \right \} * 5=\\\\= 2 * \left \{ 290 + 25 \right \} * 5=2*315*5=3150$

tangare [24]

Oldest = 2x
Middle = x + 5
Youngest = x

2x + x + 5 + x = 57
combine like terms

4x + 5 = 57
subtract 5 from both sides

4x = 52
divide both sides by 4 to isolate x

x = 13

Oldest = 2x = 2(13) = 26
Middle = x + 5 = 13 + 5 = 18
Youngest = x = 13

Answer:

The expected loss is $275 million.

Step-by-step explanation:

Expected loss can be determined as the sum of the product of each possible loss by the its probability of occurence. In this situation, there are only two possible losses listed since the probability of no loss doesn't add any value to the expected loss and should be disregarded.

Expected loss (in millions) = EL

$EL = (300*0.25)+(800*0.25)\\EL = 275$

The expected loss is $275 million.

Find all points on the curve y = cos x, 0 ≤ x ≤ 2π, where the tangent line is parallel to the line y = -x.

andre [41]

Answer:

90⁰

Step-by-step explanation:

y=cosx

y'= -sinx

eqñ of tangent is y=-x

slope of tangent =-1

we know...

slope of tangent = y' or derivative of y

-sin x = -1

sin x= 1

x = 90⁰
