Answer:
2x-3 < 7 = x ≤ 5 and 5 - x ≤ 8 = x ≥ - 3
Step-by-step explanation:
The answer is: 3
Explanation: there’s a number pattern going on, in the first example they subtract by 3 each time. In the second example they subtract by 2 each time. So for the last one you have to do 9-6 which is 3 and that’s the number pattern.
Hope I helped :)
Answer:
measure of other diagonal is 30cm
Step-by-step explanation:
let the other diagonal be d .
- area of rhombus = 1/2 × 16 × d
- 240 = 8 × d
- d = 240 / 8
- d = 30
hence the other diagonal = d = 30 cm
Answer:
the probability that at least one envelope is a yellow envelope is 16/21
Step-by-step explanation:
The probability that at least one envelope is a yellow envelope is P(Y);
P(Y) = 1 - P(Y)'
P(Y)' is the probability that no envelope is a yellow envelope.
Given;
red envelope = 1
blue envelopes = 3
green envelopes = 2
yellow envelopes = 3
Total = 9
Number of non-yellow envelope = 9 -3 = 6
(6 envelope are not yellow)
P(Y)' = P1 × P2 × P3
Since there is no replacement;
P(Y)' = 6/9 × 5/8 × 4/7
P(Y)' = 5/21
From equation 1;
P(Y) = 1 - 5/21
P(Y) = 16/21
the probability that at least one envelope is a yellow envelope is 16/21.
