Answer:

360-270=x

x=90 degrees

Step-by-step explanation:

There are two ways i know of how you can do this

<em>The first way:</em>

Ok so lets add up all the angles we know

<u><em>90+90+90=270</em></u>

Now we subtract that from 360

<u><em>360-270=90</em></u>

And there we have it the measure of angle x is 90 degrees

<em>The second way:</em>

Ok lets name all the angles we know. Hypothetically we only know that one angle is 90.

<u><em>measure of angle one is 90 degrees</em></u>

So now we subtract that from 360

<u><em>360-90=270</em></u>

Now we divide that by three because there are only 4 angles and we know the measure of one of the angles

<u><em>270/3=90</em></u>

And there we have it the measure of angle x is 90 degrees

Vlada [557]

Answer:

(-6,4)

Step-by-step explanation:

You started at (-4,2)  The first number in the ordered pair moves the number left and right and the second number moved the point up and down.

We are first told to move the point 2 units to the left.  -4 is my left right number.  If I am at -4 and I go to unites to the left, I will be at -6.  My new point is now (-6,2).  Next we are told to go up 2.  The 2 number in my ordered pair tells me that I am 2 above the x axis.  Now I am going to go two more units up.  I am now at 4, so my new ordered pair after the translation is (-6,4)

It’s around 450 euros right now - to figure this out you multiply the number of pounds by the current exchange rate ( which you can look up)

Need this please!!! Graph Y=-5x-2!!! Thanks. :-)
Andreyy89

Graph the line using the slope and y-intercept, or two points.

Slope= -5

y- intercept= (0,2)

The answer has two points (0,2) and (1,-3) place them and then make a line going left through them.

Doss [256]

Answer:

0.6,0.7,0.3 neither disjoint nor independent.

Step-by-step explanation:

Given that at a large university, 60% of the students have a Visa card and 40% of the students have a MasterCard.

A= visa card

B = Master card

P(A) = 0.60 and P(B) = 0.40

P(AUB)' = 0.30

i.e. P(AUB) = 0.70

Or P(A)+P(B)-P(AB) =0.70

P(AB)= 0.30

Randomly select a student from the university.

1) the probability that this student does not have a MasterCard.

= P(B') = 1-0.4 =0.6

2.  the probability that this student has either a Visa card or a MasterCard.

=P(AUB) = 0.70

3. Calculate the probability that this student has neither a Visa card nor a MasterCard.

=P(AUB)' = 0.30

4. Are the events A and B disjoint? Are the events A and B independent?

A and B have common prob 0.30 hence not disjoint.

P(AB) ≠P(A)P(B)

Hence not independent
