Answer:

m=20

Step-by-step explanation:

Solve the equation:

7m - 8 = 3 ( 2 m + 4)

Multiply 3 and (2m+4)

7m - 8 = 6m + 12

Add 8 to each side

7m = 6m + 20

Subtract 6m from both sides

m = 20

If my answer is incorrect, pls correct me!

seropon [69]

Answer: 0.064

Step-by-step explanation:

The formula to find the margin of error :-

E=z_{\alpha/2}\sqrt{\dfrac{p(1-p)}{n}}

Given : Significance level : \alpha=1-0.99=0.01

Critical value : z_{\alpha/2}=2.576

Sample size : n=400

The proportion of people support the candidate :p=0.44

Then , E=(2.576)\sqrt{\dfrac{0.44(1-0.44)}{400}}\approx0.064

Hence, Margin of error = 0.064

What is a reasonable estimate for 786 x 217?
zhuklara [117]

Answer:

160,000

Step-by-step explanation:

Estimations like this usually involve rounding to easy numbers to multiply. You could do this in a number of ways depending on your ability to keep track of factors in your head, but the easiest way (and what I assume your teacher is looking for) is to round to the nearest, largest-power-of-ten, which in this case is the hundreds. 786 is closest to 800, and 217 is closest to 200, and 200*800 is 160,000. No calculator required is the key. You can also be slightly more sure that this is <em>reasonable</em> because you rounded up for one and down for the other, approximately by the same amount, too.
