Answer:  

But, just how similar can they be if one is a three-sided polygon, and the other is a specific ... Parallelograms come in the form of rectangles, rhombuses, and squares. When trying to determine the area of a parallelogram, it will be necessary to ... of our base and height, we can plug these values directly into our area for

Answer:

The formula for the area of a parallelogram is A = bh, and the formula for area of a triangle is A = 1/2bh. Since a triangle is half of the area of a parallelogram with the same base and height, the only difference in the formula is 1/2.

An instructor believes the distribution of scores on her final exam will have mean 62 and standard deviation 7. Fred is a studen
OLga [1]

Answer:

a) P(47

And then the probability that Fred will not score between 47 and 77 is

1-0.968 = 0.0321

b) P(45

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".  

Part a

Let X the random variable that represent the scores of a population, and for this case we know the distribution for X is given by:

X \sim N(62,7)  

Where \mu=62 and \sigma=7

We are interested on this probability  on the probability that Fred will not score between 47 and 77. So we can begin finding this probability

P(47

And the best way to solve this problem is using the normal standard distribution and the z score given by:

z=\frac{x-\mu}{\sigma}

If we apply this formula to our probability we got this:

P(47

And we can find this probability on this way:

P(-2.143

And in order to find these probabilities we can find tables for the normal standard distribution, excel or a calculator.  

P(-2.143

And then the probability that Fred will not score between 47 and 77 is

1-0.968 = 0.0321

Part b

P(45

And we can find this probability on this way:

P(-2.429

And in order to find these probabilities we can find tables for the normal standard distribution, excel or a calculator.  

P(-2.429

Write the following expression in the form of 4^n
pishuonlain [190]

Answer:

4^7

Step-by-step explanation:

4 * 4 * 4 * 4 = 256

4 * 4 * 4 = 64

Since the number is the same, another way to write the expression is 4^7.

256 * 64 = 16,384

Hope I helped! Please give me brainliest!
