Find x Help me please

Mathematics
1 answer:
ch4aika [34]2 years ago
3 0

Answer:

x=31.2

Step-by-step explanation:

Since angle C is 4x-10 and angle A is 2x+3

then the two angles combined should equal 180 (based off of the inscribed quadrilateral theorem)

4x-10+2x+3=180

6x-7=180

6x=187

x=31.166...

if you round it to the nearest tenth it would be 31.2

kondaur [170]

Answer:

E

Step-by-step explanation:

\sqrt{a} × \sqrt{b} ⇔ \sqrt{ab}, hence

\sqrt{-12}

= \sqrt{4(3)(-1)} = \sqrt{4} × \sqrt{3} × \sqrt{-1} [\sqrt{-1} = i]

= 2i\sqrt{3} → E

Hospital records show that a certain surgical procedure takes on an average 111.6 minutes with a standard deviation of 2.8 minut
Arisa [49]

Answer:

At least 37.74% of the procedures takes between 97.6 and 125.6 minutes

Step-by-step explanation:

The percentage is the area of the standard normal distribution curve between the values 97.6 and 125.6

The standard normal variate of the given data is found as

Z=\frac{X-\overline{X}}{\sigma }

Thus for the given values Z is calculated as under

Z_1=\frac{97.6-111.6}{2.8}=-5

Similarly for the other value we have

Z_2=\frac{125.6-111.6}{2.8}=5

Thus the area between the calculated values can be found from standard normal distribution table to be 37.74%

There are 60 minutes in an hour, thus

56 minutes = \frac{56}{60} of an hour

To simplify divide 56 and 60 by 4

56 minutes = \frac{14}{15} ← in simplest form
