What number must you add to complete the square?

emmasim [6.3K]

X^2 + 2x = -1......take half of ur x term (2x), and square it. So we take half of 2, which is 1, and square it....1^2 = 1....so u would add 1 to both sides

Suppose that the ages of members in a large billiards league have a known standard deviation of σ = 12 σ=12sigma, equals, 12 yea

asambeis [7]

Answer:

$n\geq 23$

Step-by-step explanation:

-For a known standard deviation, the sample size for a desired margin of error is calculated using the formula:

$n\geq (\frac{z\sigma}{ME})^2$

Where:

$\sigma$ is the standard deviation
$ME$ is the desired margin of error.

We substitute our given values to calculate the sample size:

$n\geq (\frac{z\sigma}{ME})^2\\\\\geq (\frac{1.96\times 12}{5})^2\\\\\geq 22.13\approx23$

Hence, the smallest desired sample size is 23

7x+3+6x+11 i need help solving this problem

____ [38]

Step-by-step solution:

7x + 3 + 6x + 11 = 0

7x + 6x + 11 + 3 = 0

13x + 11 + 3 = 0

13x + 14 = 0

13x = 0 - 14

13x = -14

x = -14 / 13

x = -1.077 approx.
