Answer with explanation:

The formula of Z score is

  Z_{Score}=\frac{\Bar X-\mu}{\sigma}\\\\ Z_{7 \text{Percent}}

The value of temperatures are that separates the top​ 7% from the bottom​ 93% are:⇒

 98.53 < Temperature in degrees < 98.72

Answer: The temperature that separates the top 7% with the bottom 93% is 99.12 degrees.

The z-score that corresponds to 93% is about 1.48. If we write the equation for the z-score, we can solve for the missing temperature.

The equation would be:
(x - 98.2) / 0.62 = 1.48
x - 98.2 = 0.9176
x = 99.12 degrees

Help me please!!! Help will be appreciated
vitfil [10]
The answer is 22.5 because the total area is 45 if you count it, and it says each is 1/2.

1/2 * 45 = 22.5.

Hope this helped☺☺

A square technology chip has an area of 25 square centimeters how long is each side of the chip
grigory [225]

ANSWER

Each side of the chip is 5 centimeters long.


<u>EXPLANATION</u>

The chip is in the form of a square.


The formula for finding the area of a square is

Area=l^2


We were given in the question that, the area is 25 square centimeters. This means that,


25=l^2


We take the square root of both sides to get,


\sqrt{25}=l


\Rightarrow 5=l


Hence the length of the square technology chip is 5 centimeters

What is the solution for 5x^2-x+6=0
kati45 [8]

The easiest way to solve this problem is by using the Pythagorean theorem :D

Pythagorean theorem: [-b +- sqrt(b^2 - 4ac)]/2a

5 = a

-1 = b

6 = c

therefore, by plugging these values in!

[-(-1) +- sqrt((-1)^2 - 4(5)(6))]/2(5)

[1 +- sqrt(1 - 120)]/10

Oh so we're using imaginary numbers, so in this case you'll need to know that i = sqrt(-1), so keep this in mind (I can see why this was so difficult)

[1 +- sqrt(119)*i]10

answers:

( 1 + i*sqrt(119) ) / 10

( 1 - i*sqrt(119) ) / 10
