Answer:

0.1395

Step-by-step explanation:

We are given that Q and R are independent events.

P(Q)=0.45

P(R)=0.31

We have to find the value of P(Q and R).

We know that when two events are independent then

P(A\cap B)=P(A)\cdot P(B)

P(Q\cap R)=0.45\times 0.31=0.1395

Answer:P( Q and R)=0.1395

Either 7 or 23 - read note

Step-by-step explanation:

Substitute m for 8.

*Note: I'm not sure if anything is in parentheses so there are two possible answers depending on whether you want it done left to right or by order of operations*

Left to Right:

3(8) - 3 ÷ 3

24 - 3 ÷ 3

21 ÷ 3

7

Order of Operations:

3(8) - 3 ÷ 3

24 - 3 ÷ 3

24 - 1

23

icang [17]

Answer:

the sum is 360 degrees, which means

360 = 124 + 124 + 2x + 2x

360 = 248 + 4x

-4x = 248 - 360

-4x = -112

x = 28

Check:

124 + 124 + 2(28) + 2(28) =

360

Your answer is x = 28

One angle in an obtuse isosceles triangle measures 40°. What are the measures of the other two angles?
Damm [24]
An obtuse triangle has one obtuse angle, or an angle that measures more than 90° but less than 180°. Options 1 and 2 are not correct, because these are acute angles.
So, one of the angles must be 40°, and the other may be 100° or 120°.
The measures of the angles in a triangle add up to 180°.
40^\circ + 40^\circ +x = 180^\circ \\&#10;80^\circ + x=180^\circ \\&#10;x=180^\circ - 80^\circ \\&#10;x=100^\circ
The other two angles are 40° and 100°.

last minute forgot to do it please help and do all of them and I have one more I promise I’ll give you good ratings :D
Zolol [24]

1.) The error is that she attached the

variable with the flat fee (which is

constant) and put the daily rent as a

constant (which is variable).

The correct equation is:

365+125x=250+175x

2.) N=5

3.) k=-35.

Explanation: Solution:

17k-6=37k+4 . 17k-37k=4+6 .

-27k=10 . k=10\cdot(7-2) . k=-35 .

4.)

y =   - \frac{9}{16}
