Solve the following proportion for 17/13=9/u

ValentinkaMS [17]

Answer:

Solution,

$\frac{17}{13} = \frac{9}{u}$

Sinplify the equation using cross multiplication

$17 \times u = 13 \times 9$

Calculate the product

$17u = 117$

Divide both sides of the equation by 17

$\frac{17u}{17} = \frac{117}{17}$

Calculate

$u = 6.88$

Hope this helps...

An average light bulb manufactured by the Acme Corporation lasts 300 days with a standard deviation of 50 days. Assuming that bu

notsponge [240]

Answer:

1. 90% 2. 10% 3. 50%

Step-by-step explanation:

Standard Deviation (σ) = 50 days

Average/Mean (μ) = 300days

Probability that it would last more than 300 days = P(Bulb>300 days)

We will assume there are 365 days in a year.

P(Bulb>300 days) implies that the bulb would

Using the normal equation;

z = standard/normal score = (x-μ)/σ where x is the value to be standardized

P(Bulb>300 days) implies x = 365 days

Therefore z = (365-300)/50 = 1.3

Using the normal graph for z=1.3, probability = 90%

2. P(Bulb<300 days) = 1 - P(Bulb>300 days)\

P(Bulb<300 days) = 1 - 0.9

P(Bulb<300 days) = 10%

3. P(Bulb=300 days) implies z=0 since x=300

Using the normal graph for z=0, probability =50%
