Answer:
A: 20:10=2:1
B: y=2x
c he can have 2 flowers per seed packet
Step-by-step explanation:
A: When you look at the coordinates of the graph, you can see the proportionallty at point (10/20)
B: the equoation is proportionalty multplied by x + y axis section (in this case 0)
C: The proportionality explains the relationship:
x represents the flowers
y represents the seed packets

5x9= 45 remainder3 which means it 9 3/5
Answer:
x = 1/3
Step-by-step explanation:
15 = 1/2 + 3/2x + 10
15 - 1/2 -10 = 3/2x
9/2 = 3/2x
9 x 2x = 3 x 2
18x = 6
x = 6/18
x = 1/3
Answer:
Z=2.36
P=0.0091
Step-by-step explanation:
The hypothesis is:
π > 0.55 which is the population proportion
The formula to get the test statistic is
Zstat = P-π/√π(1-π)/n
P =507.4/860 = 0.59 (sample proportion )
n =860 (sample size)
π =0.55(population porportion)
Zstat = 0.59-0.55/√0.55(1-0.55)/860
Zstat =2.36
From Z table the probability of Z score of 2.36 is 0.9909
To calculate for P- value will then be
P= 1 - 0.9909
P= 0.0091
