Answer:
x=4-y/2
Step-by-step explanation:
subtract 3y from both sides
simplify
divide both sides by 6
Answer:
5 / 13 is the fraction of girls on the field trip
5/13 * 130 = 50 girls on the trip
Or 10 groups of 13 and each group of 13 had 5 girls giving a total of
5 * 10 = 50 girls
Answer:
a) 47.7%
b) 87.2%
Step-by-step explanation:
Find the ratio of interest, and convert it to a percentage.
<h3>a) </h3>
(messy right-handed writers)/(right-handed writers)
= 31/65 = 31/65 × 100% ≈ 47.7%
__
<h3>b) </h3>
(neat right-handed writers)/(neat writers)
= 34/39 = 34/39 × 100% ≈ 87.2%
Answer:
1. 50%
2.
Step-by-step explanation:
1. The way to approach the probability of rolling an odd number is to start with the total numbers. Therefore, each dice has three even sides and three odd sides. Mathematically - 50% chance of landing on the odd number.
2. You have 'P' which represents probability. "N" which is the given ratio of the number of outcome. (NP) total number of the possible outcome.
P = N / NP
Dice has 6 faces. I.E. 1,2,3,4,5,6
= 6
NP, therefore, is the total number of possible outcome.
Faces less than 6. (1,2,4, and 5)
N = 5
P = N / NP =
; it can't be reduced.
