15 picks are oranges
Answer:
2 ORANGE = 5 GREEN
GREEN = 2/5 ORANGE = 0.4 ORANGE
---
ORANGE + GREEN = 21
ORANGE + 0.4 ORANGE = 21
1.4 ORANGE = 21
ORANGE = 15

Answer:
★ The two factors of the number 221 are 13 and 17.
A factor refers to a whole number, which fits evenly into another whole number. Thus, factors are the numbers, which we multiply together to get another number. The two numbers that can be multiply together to get 221 are 13 and 17.

Answer:
The amount of money
Step-by-step explanation:
The amount of money depends on how many chores you do. The dependent variable is the money, and the independent variable is the amount of chores.
Answer:
(a) P(X = 18) = 0.25
(b) P(X > 18) = 0.53
(c) P(X ≤ 18) = 0.47
(d) Mean = 19.76
(e) Variance = 22.2824
(f) Standard deviation = 4.7204
Step-by-step explanation:
We are given that discrete random variable X has the following probability distribution:
X P (x) X * P(x)
* P(x)
13 0.22 2.86 169 37.18
18 0.25 4.5 324 81
20 0.20 4 400 80
24 0.17 4.08 576 97.92
27 0.16 4.32 729 116.64
(a) P ( X = 18) = P(x) corresponding to X = 18 i.e. 0.25
Therefore, P(X = 18) = 0.25
(b) P(X > 18) = 1 - P(X = 18) - P(X = 13) = 1 - 0.25 - 0.22 = 0.53
(c) P(X <= 18) = P(X = 13) + P(X = 18) = 0.22 + 0.25 = 0.47
(d) Mean of X,
= ∑X * P(x) ÷ ∑P(x) = (2.86 + 4.5 + 4 + 4.08 + 4.32) ÷ 1
= 19.76
(e) Variance of X,
= ∑
* P(x) -
= 412.74 -
= 22.2824
(f) Standard deviation of X,
=
=
= 4.7204 .
