Solving the inequality -3q+12\geq 4q-30 the value of q is q\leq 6

Step-by-step explanation:

We need to solve the inequality: -3q+12\geq 4q-30 and find value of q

Solving:

-3q+12\geq 4q-30\\Adding\,\,-12\,\,on\,\,both\,\,sides:\\-3q+12-12\geq 4q-30-12\\-3q\geq 4q-42\\Adding\,\,-4q\,\,on\,\,both\,\,sides:\\-3q-4q\geq 4q-42-4q\\-7q\geq -42\\Divide\,\,both\,\,sides\,\,by\,\,7\\\frac{-7q}{7}\geq \frac{-42}{7}\\ -q\geq -6\\Multiply\,\,both\,\,sides\,\,by\,\,-1\,\,and\,\,reverse\,\,the\,\,inequality:\\q\leq 6

So, solving the inequality -3q+12\geq 4q-30 the value of q is q\leq 6

Answer:

B.   60x^8

Step-by-step explanation:

4x^2\sqrt{5x^4} \cdot 3\sqrt{5x^8} =

= 4x^2 \times 3 \sqrt{5x^4 \times 5x^8}

= 12x^2 \sqrt{25x^{4+8}}

= 12x^2 \sqrt{25} \sqrt{x^{12}}

= 12x^2 \times 5 \times x^6

= 60x^8

 A map of a highway has a scale of 2 inches equals 33 miles. The length of the highway on the map is 6 inches. There are 11 rest
vfiekz [6]

Answer:

The answer is "0.975"

Step-by-step explanation:

Please find the complete question in the attched  file.

Find the remaining distance inside the original map

\to \frac{9}{6}=1.5  \ in

Dividing the value by 6 because there are 7 rest stop:

\to \frac{2 \ inches}{39 \ inches} =\frac{1.5 \ inches}{x \ miles}\\\\\to x=39 \times \frac{1.5}{2}\\\\\to  x=29.25 \ miles

Finding the diatance of the rest stop in the new map

Using proportion:

\to \frac{1 \ inches}{30 \ miles} =\frac{x \ inches}{ 29.25 \ miles}\\\\\to  x= \frac{29.25}{30}\\\\\to  x=0.975 \ in

In estimating the mean score on a fitness exam, we use an original sample of size n 3 and a bootstrap distribution containing 50
maw [93]

Answer:

C) 67.5 to 72.5

Step-by-step explanation:

The value to calculate the confidence interval is given as:

(x-z_{\frac{\alpha}{2}} \times \frac{\sigma}{\sqrt{n}},x-z_{\frac{\alpha}{2}} \times \frac{\sigma}{\sqrt{n}})

Margin of error is given by:

z_{\frac{\alpha}{2} } \times \frac{\sigma}{\sqrt{n}}

Using a sample of size n = 3, with 95% confidence the confidence interval came out to be 67 to 73.

We need to identify the new confidence interval if the sample size is increased to n = 16

If you observe the formula, you will see that the sample size(n) is in the denominator. This means, if value of n will be increased the value of fraction will be decreased, which will result in an overall smaller value of margin of error. Since, margin of error is smaller, the values of confidence interval will be closer to the mean.

From here, we can conclude that if sample size is increased, the confidence interval will get narrower. From the given options only option C contains a narrow confidence interval. Therefore, correct answer will be option C: 67.5 to 72.6
