Z^5=-7776iFind the solution of the following equation whose argument is strictly between 270 and 360 degrees

Answers

Answer:

Z=+6

Step-by-step explanation:

Z^5=-7776i

Let's note that i I mathematics means negative one i.e

i = -1

So the equation is equal to

Z^5=-*-(7776)

Z^5 = 7776

Z= 5√7776

Since it's a divisible by 6

It's giving us a clue that 6 it's the answer.

Ok let's check the 5th root of 7776 in our calculator.

Z=+6

+6 is the solution to the equation

Z^5=-7776i

Prices were recorded for all the loaves of bread in a supermarket, the mean price for a loaf of bread was $1.37 with a standard deviation of $0.67, Find the probability that if 13 loaves are selected the mean price is less than $1.00. A 0.0032

B 0.5643

C 0.9105

D 0.0233

Answers

Answer:

$z = (1-1.37)/((0.67)/(√(13))) = -1.991$

And we want this probability:

$P(z<-1.991)$

And using the normal standard distribution or excel we got:

$P(z<-1.991)= 0.0233$

And the best option would be:

D 0.0233

Step-by-step explanation:

For this case we have the following parameters:

$\mu = 1.37, \sigma =0.67$

And we select a sample size of n=13. And we want to find this probability:

$P(\bar X <1)$

We can assume that the distribution for this case is normal and then we can use the z score formula given by:

$z= (\bar X -\mu)/((\sigma)/(√(n)))$

And if we replace the data given we got:

$z = (1-1.37)/((0.67)/(√(13))) = -1.991$

And we want this probability:

$P(z<-1.991)$

And using the normal standard distribution or excel we got:

$P(z<-1.991)= 0.0233$

And the best option would be:

D 0.0233

Show how to solve 378*6 using place value with regrouping. Explain how you knew when to regroup.

Answers

To regroup 378 x 6, you must first establish the place values of each digit. 3 has a place value of 300, because it is in the hundreds column; 7 has a place value of 70 because it is in the tens column; 8 has a place value of 8 because it is in the units column. This means you can regroup 378 x 6 as (300 x 6) + (70 x 6) + (8 x 6). This makes 2,268.
