Answer: 42) 2, 3       43) 144

<u>Step-by-step explanation:</u>

42)

1. n(P) = 8 + 5 = 13 (not 8)                           This statement is False.

2. n(Q but not P) = 9                                   This statement is True!

3. n(neither P nor Q) = 2                             This statement is True!

4. n(Q') --> (n (not Q) = 8 + 2 = 10 (not 8)    This statement is False.

5. P ∪ Q = 8 + 9 - 5 = 12 (not 5)                   This statement is False.

43)

Fill in the Venn Diagram as follows (from left to right):

     M only = 55           --> 89 - (17 + 4 + 13) = 55

       M ∩ E = 17           --> 30 - 13 = 17

       E only =  5            --> 46 - (17 + 13 + 11) = 5

       B ∩ M =  4             --> 17 - 13 = 4

M ∩ E ∩ B = 13           --> given

        B ∩ E = 11             --> 24 - 13 = 11

      E only = 35           --> 63 - (13 + 4 + 11) = 35

<u>(M ∪ E ∪ B)' = 4    </u>        --> given

         Total = 144

Fill in the table using this function rule.<br> y=29-4x
NeTakaya

Answer:

25, 21, 13, 9

Step-by-step explanation:

All you do here is plug in the X from the table to the X in the equation so,

y=29 - 4 x 1 = 25

y=29 - 4 x 2 = 21

y=29 - 4 x 4 = 13

y=29 - 4 x 5 = 9

Very confused need lots of help
Karo-lina-s [1.5K]

Answer:

The angle is 50 degrees.

Step-by-step explanation:

You'll see, the angle that is on the left of the 70° angle has to be 110°, because a straight line has 180°.

Now, the inner angles of a triangle have to sum 180°. So if the lower angle is 110° (because you just calculated it), and the upper angle is 20°, the third angle is:

180° = 110° + 20° + x

180° = 130° + x

180° - 130° = x

50° = x

Now this third angle is on the bottom left part of the triagle, and it's 50°. It also opposite to the angle 1, which is the one you want to calculate. Because they are opposites, they are identical, meaning that they both are 50°. This is due to a geometrical rule.

Nicole rented a bike from Krystal's Bikes. It costs $15 plus $7 per hour. If Nicole paid $43, then she rented the bike for how m
murzikaleks [220]

Given that Nicole rented a bike from Krystal's Bikes, the number of hours is

4 hours

Given data

Initial Cost  = $15

Cost per extra hours = $7

Amount Paid = $43

The Expression that we will use to describe this situation is modelled below

let y = Amount paid

    m = cost per extra hour

    x = the number of hours

   c = the initial cost

y = mx + c -------- Equation of line

43 = 7*x + 15

43 = 7x+15

7x = 43-15

7x = 28

divide both sides by 7

x= 28/7

x= 4 hours

Hence the number of hours is 4 hours
