An amtrak train travel at 125 miles per hour.convert the speed to miles per minute.round to the nearest tenth

creativ13 [48]

Answer:

If you told me how to put this into math w ay as a equation, I would be glad to solve it for you... I will edit this once I find the right answer! Sorry I couldn't find it right away :(

Step-by-step explanation:

Edit= I think is would be around 149.328 grams because 56 is 62.22 percent of 90 and 62.22 percent of 240 is 149.328. If this is incorrect I apologize in advance!

Not sure how to figure out how to get b2 by itself..can anyone help me out?

Arte-miy333 [17]

As with any "solve for ..." problem, you start by looking at the operations performed on the variable of interest. Here, when you evaluate this expression according to the order of operations, you

add b1
multiply by (h/2)

When you want to solve for b2, you undo these operations in reverse order. To undo multiplication by a fraction, you multiply by the inverse (reciprocal) of the fraction. To undo addition, you add the opposite.

Whatever you do must be done to both sides of the equation.

Here we go ...

... (2/h)A = b1 + b2 . . . . . we undid the multiply by h/2, by multiplying by 2/h

... (2/h)A - b1 = b2 . . . . . we undid the addition of b1 by adding the opposite of b1

Then your solution is

... b2 = 2A/h - b1

If you want to, you can combine these terms over a single denominator to get

... b2 = (2A -h·b1)/h

Katen [24]

Answer:

The probability that the sample proportion is within 0.03 of the population proportion is 0.468.

Step-by-step explanation:

The complete question is:

A company makes auto batteries. They claim that 84% of their LL70 batteries are good for 70 months or longer. Assume that this claim is true. Let p^ be the proportion in a random sample of 60 such batteries that are good for 70 months or more. What is the probability that this sample proportion is within 0.03 of the population proportion? Round your answer to two decimal places.

Solution:

According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.

The mean of this sampling distribution of sample proportion is:

$\mu_{\hat p}=p\\$

The standard deviation of this sampling distribution of sample proportion is:

$\sigma_{\hat p}=\sqrt{\frac{p(1-p)}{n}}$

The information provided is:

$p=0.84\\n=60$

As the sample size is large, i.e. <em>n</em> = 60 > 30, the Central limit theorem can be used to approximate the sampling distribution of sample proportion of LL70 batteries that are good for 70 months or longer.

Compute the probability that the sample proportion is within 0.03 of the population proportion as follows:

$P(-0.03$

Thus, the probability that the sample proportion is within 0.03 of the population proportion is 0.468.
