95% of the nails would fall within 1 standard deviation. This means 95% of the nails would be between 5 - 0.03 = 4.97 and 5 + 0.03 = 5.03 inches long.

this would mean that 5% of the nails would either be longer than 5.03 or shorter than 4.97 inches.

One half of 5% is 2.5%.

Multiply the total nails by 2.5%:

120 nails x 0.025 = 3 nails would be less than 4.97 inches.

Select the correct answer<br> Solve this equation<br> X+4/6x = 1/x
laila [671]

Answer:

A) x = 0, 2

Step-by-step explanation:

(x + 4) / 6x =  1 / x

this is a proportion, so you can cross-multiply and get:

x(x + 4) = 6x

x² + 4x = 6x

x² - 2x = 0

x(x - 2) = 0

x = 0

x - 2 = 0  so, x = 2

A company has a budget of $280,000 for computing equipment. Tablets cost $500 each, laptops cost $2000 each, and servers cost $5
Kazeer [188]

Answer:

The number of tablets  200

the number of laptops  40

and, the number of servers 20

Step-by-step explanation:

Let the number of tablets be 'x'

the number of laptops be 'y'

and, the number of servers be 'z'

According to the given question

Total budget = $280,000

Tablets cost = $500 each

laptops cost = $2000 each

servers cost = $5000 each

Thus,

500x + 2000y + 5000z = 280,000 ..............(1)

also,

x = 5y  ................(2)

and,

y = 2z  

or

z = \frac{\textup{y}}{\textup{2}}   ............(3)

substituting y from 2 and 3 in equation 1,  we get

(500 × 5y) + (2000 × y) + (5000 × \frac{\textup{y}}{\textup{2}} ) = 280,000

or

2500y + 2000y + 2500y = 280,000

or

7000y = 280,000

or

y = 40

substituting y in equation 2, we get

x = 5 × 40 = 200

substituting y in equation 3 we get

z = \frac{\textup{40}}{\textup{2}}

or

z = 20

hence,

the number of tablets  200

the number of laptops  40

and, the number of servers 20
