Juliette [100K]

Answer: 0.4667

Step-by-step explanation:

According to 68–95–99.7 rule , About  99.7% of all data values lies with in 3 standard deviations from population mean (\mu).

Here , margin of error = 3s , where s is standard deviation.

As per given , we have want our sample mean \overline{x} to estimate μ μ with an error of no more than 1.4 point in either direction.

If 99.7% of all samples give an \overline{x} within 1.4 , it means that

3s=1.4

Divide boths ides by 3 , we get

s=0.466666666667\approx0.4667

Hence, So \overline{x} must have 0.4667 as standard deviation so that 99.7 % 99.7% of all samples give an \overline{x} within 1.4 point of μ .

X^2 +6x+30 in vertex form
Elina [12.6K]

Answer:

Step-by-step explanation:

Factoring  x2-6x-30

The first term is,  x2  its coefficient is  1 .

The middle term is,  -6x  its coefficient is  -6 .

The last term, "the constant", is  -30

Step-1 : Multiply the coefficient of the first term by the constant   1 • -30 = -30

Step-2 : Find two factors of  -30  whose sum equals the coefficient of the middle term, which is   -6 .

     -30    +    1    =    -29

     -15    +    2    =    -13

     -10    +    3    =    -7

     -6    +    5    =    -1

     -5    +    6    =    1

     -3    +    10    =    7

     -2    +    15    =    13

     -1    +    30    =    29
