in a ceremony out of 800 participants 620 drink milk 350 drank tea and 50 did not drink both. find out how many people drank the both drink using a Venn diagram

220:goodnight mark me brainliest

Explanation: Let M represent the amount of people that drank milk, let T represent the people that drank tea.

Let x represent the people that drank both milk and tea.

Therefore. the amount of people that drank only milk = n(M ∩ T') = 620 - x

the amount of people that drank only milk = n(M' ∩ T) = 350 - x

The amount of people that did not drink any of them = n(M ∪ T)'

Since 800 people participated, Hence:

620 - x + (350 - x) + x + 50 = 800

620 + 350 + 50 - x - x + x = 800

1020 - x = 800

x = 1020 - 800

x = 220

Therefore 220 people drank both drinks.

answer: 25.4 units

step-by-step explanation: radius = 12.7 units

diameter = twice the radius

diameter = 12.7 x 2

= 25.4

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
