whats the solution to -12x ≤ -72

Answer:

The 95% confidence interval for the difference is (-0.1888, 0.0202).

Step-by-step explanation:

Difference between proportions:

The distribution of the difference between two proportions has mean of the difference between these proportions and standard deviation is the square root of the sum of the variances. So

In a sample of 86 units made with gold wire, 68 met the specification

This means that:

[tex]pX = \frac{68}{86} = 0.7907[/tex]

[tex]sX = \sqrt{\frac{0.7907*0.2093}{86}} = 0.0439[/tex]

In a sample of 120 units made with aluminum wire, 105 met the specification.

This means that:

[tex]pY = \frac{105}{120} = 0.875[/tex]

[tex]sY = \sqrt{\frac{0.875*0.125}{120}} = 0.0302[/tex]

Difference:

[tex]p = pX - pY = 0.7907 - 0.875 = -0.0843[/tex]

[tex]s = \sqrt{sX^2 + sY^2} = \sqrt{0.0439^2+0.0302^2} = 0.0533[/tex]

Confidence interval:

[tex]p \pm zs[/tex]

In which z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex], with [tex]\alpha[/tex] being 1 subtracted by the confidence level.

95% confidence level

So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

Lower bound of the interval:

[tex]p - zs = -0.0843 - 1.96*0.0533 = -0.1888[/tex]

Upper bound of the interval:

[tex]p + zs = -0.0843 + 1.96*0.0533 = 0.0202[/tex]

The 95% confidence interval for the difference is (-0.1888, 0.0202).

Multiply y by 6 then divide the product by 7=6y divided by 7 or 6y/7

Step-by-step explanation:

9514 1404 393

Answer:

Step-by-step explanation:

Assuming you're interested in the number of each that were sold, the system of equations will express the relation for total sold, and the relation for total revenue. We have used the variable c and p to represent numbers of cakes and pies sold, respectively. Your choices may use x and y, instead.

__

The solution can be found by subtracting 6 times the first equation from the second. That tells you 6 cakes were sold, hence 4 pies.

Answer:

q < 6

Step-by-step explanation:

9 + q < 15                                                                                                                 subtract 9 from both sides        

Answer:

Answer:

30 units^2

Step-by-step explanation:

Answer:

30

Step-by-step explanation:

Multiply length times width

Each side is 6 units. That would be your length

And both the top and bottom are 5 units each. This would be your width.

5 times 6= 30

Answer:

2.2 or -2.2

Step-by-step explanation:

-5x^2=-25 first, divide by -5

x^2=5 next, take the square root of 5

The square root of 5 is approximately 2.2, and so you get either 2.2 or -2.2, since a negative times a negative is a positive, so it could be -2.2 as well.

Answer:

The answer is n < 6.

Step-by-step explanation:

[tex] \frac{n}{3} < 6 - 4[/tex]

[tex] \frac{n}{3} < 2[/tex]

[tex]n < 2 \times 3[/tex]

[tex]n < 6[/tex]

Therefor, the answer is n < 6.

49

Step-by-step explanation: no idea i just evaluated like that

Answer:

49

Step-by-step explanation:

Alrighty, PEMDAS, lets get started:

9 + 3(10 ÷ 2) + 5²

So we start with the parenthesis:

10 ÷ 2 = 5

Now we do the exponent:

5² = 25

So we now have:

9 + 3 x 5 + 25

we do multiplication first:

3 x 5 = 15

so we have:

9 + 15 + 25 = 49

So 9 + 3(10 ÷ 2) + 5² = 49
