Answer:

10% of the people at the picnic are neither.

Step-by-step explanation:

To get the answer,

1/2 + 2/5 = 9/10

10/10 - 9/10 = 1/10

1/10 = 10%

Thanks, I hope I got this right!

The probability that any postcard posted in Portugal on Monday is delivered to the UK within a week is 0.62.

sashaice [31]

Answer:

You can expect at least 9 of her postcards to arrive within a week

To find that, we multiply the number of postcards by the probability

15 x 0.62 = 9.3

Hope this helps

Consider the set T = {1, 2, 3, 4, 5, 6}. Let R = {(a, b) | a divides b} be a relation on the set T. Identify the missing ordered

serg [7]

Answer: The missing ordered pairs are (2, 2), (2, 4), (2, 6), (3, 3) and (3, 6).

Step-by-step explanation: We are given the following set :

T = {1, 2, 3, 4, 5, 6}.

And, R = {(a, b) | a divides b} be a relation on the set T.

We are to identify the missing pairs from the following list of all ordered pairs in the given relation R on the set T :

{(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6), _____, (4, 4), (5, 5), and (6, 6).}.

Since R contains the ordered pairs (a, b) such that a divides b, so all the ordered pairs in R are

(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6), (2, 2), (2, 4), (2, 6), (3, 3), (3, 6), (4, 4), (5, 5), and (6, 6).

Thus, the missing ordered pairs are (2, 2), (2, 4), (2, 6), (3, 3) and (3, 6).

5. You are making your weekly mean plans and are working with the following constraints: It costs $8 to go out to dinner. It cos

Goshia [24]

Let

x-------> the number of dinner

y-------> the number of lunch

we know that

$8x+5y \leq 42$ -------> equation A

$x=y$ ------> equation B

Substitute equation B in equation A

$8[y]+5y \leq 42$

$13y \leq 42$

$y \leq 42/13$

$y \leq 3.23$

the greatest number of lunch is $y=3$

$x=y$

Hence

the greatest number of dinner is $x=3$

therefore

the greatest number of meals is

$x+y=3+3=6$

the answer is

$6$
