Since it is super-urgent, it is probably a test or quiz. I should not have answered the question. I will help by giving you an example. You will need to work it out using a calculator. This is the best I can do.
Well, you just divide 7056 by a guess number x.
Take the average of x and the quotient (result of division) and repeat again.
Example:
Find square-root of 700, with an initial guess of x=27.
The quotient is 25.92592592592592
Taking average of 25.92592592592592 and 27 gives 26.46296296296296.
Using new guess x=26.46296296296296 and repeat the same process, we get 26.45751367182438
Using the new guess x=26.45751367182438 and repeat the same process, we get 26.45751311064591 which is accurate to 13 places after the decimal.
If it is not clear, try finding square-root of 625 and the final answer should be 25 (exactly) after three or four repetitions.
Feel free to ask for more <em>explanations</em>.
Your answer is 250
Step-by-step explanation:
10 x 5. Multiply that.
Then multiply your final answer of 50.
250.
(-6,6)(-6,2)
notice how ur points have the same x coordinates....this means that u have a vertical line which has an undefined slope. Being that the slope is undefined, u cannot write the vertical line in slope intercept or point slope form.
Answer:
0.3085,0.2417,0.0045
Step-by-step explanation:
Given that X, the amount of money spent at shopping centers between 4 P.M. and 6 P.M. on Sundays has a normal distribution with mean $85 and with a standard deviation of $20.
X is N(85, 20)
To convert into std normal variate we use the following formula
![Z=\frac{x-85}{20}](https://tex.z-dn.net/?f=Z%3D%5Cfrac%7Bx-85%7D%7B20%7D)
a) the probability that he has spent more than $95 at the mall
=
b. the probability that he has spent between $95 and $115 at the mall
=
c. If two shoppers are randomly selected, what is the probability that both shoppers have spent more than $115 at the mall
=product of two probabilities since independent
= ![{P(X>115)}^2\\= P(Z>1.5)*P(Z>1,5)\\= 0.0668^2\\=0.0045](https://tex.z-dn.net/?f=%7BP%28X%3E115%29%7D%5E2%5C%5C%3D%20P%28Z%3E1.5%29%2AP%28Z%3E1%2C5%29%5C%5C%3D%200.0668%5E2%5C%5C%3D0.0045)
Answer:
4x
Step-by-step explanation:
When you have a parallel line, the slope of the line is the same. So the slope of (-4,3),(-4,7)=4 would be the same as for example 4x+5
