Answer:

0.91

Step-by-step explanation:

The total of all numbers in the diagram is 35 +5 +10 +5 = 55.

The total of the numbers inside one or both circles is 35 +5 +10 = 50.

The probability of choosing a random student from inside one or both circles (plays some instrument) is 50 out of 55, or ...

50/55 ≈ 0.9090909... ≈ 0.91

P(A∪B) ≈ 0.91

5. 40 = }(9x + 30) + 2

Anvisha [2.4K]

Answer:

x=-16

Step-by-step explanation:

We are given with the equation

$40=-\frac{1}{3} \times (9x+30)+2$

We are asked to solve it for x.

Distributing $\frac{1}{3}$ over bracket and simplifying

$40=-(\frac{9x}{3}+\frac{30}{3})+2$

$40=-(3x+10)+2$

$40=-3x-10+2$

$40=-3x-8$

Adding 8 on both sides

$48=-3x$

Dividing both sides by -3

$x=-16$
