100% - (39% + 28% + 13%) = 100% - 80% = 20%
so 20% are watermelons.
20% of 1505...
0.20(1505) = 301
so 301 are watermelons
9514 1404 393
Answer:
742
Step-by-step explanation:
v = p - 0.30·p = 0.70p . . . . . 30% less than Peeta
v = 0.70(1060) = 742
Val scored 742 points.
Answer: Yes, they are equal
lets see how,
solve the given equation,
–3(0.15 – 0.2 + 0.25p)
Step 1: Inside the bracket solve the similar variables i.e. (0.15 - 0.2)
So it will become,
= -3 ( -0.05 + 0.25p )
Step 2: Multiply each term in the bracket by -3
So it will be,
((-3*-0.05 ) + (-3 * 0.25p))
= 0.15 - 0.75p
Hence 0.15 – 0.75p is equal to –3(0.15 – 0.2 + 0.25p )
12.60 because 3x1.75=5.25 and 4.2x1.75=7.35 and if you add 5.25 and 7.35 it equals 12.60
Answer: (0.143, 0.257)
Step-by-step explanation:
Given : Level of significance : 
Then , significance level : 
Since , sample size : 
.
Critical value : 
Also, the proportion of people said that they were fans of the visiting team :-
The confidence interval for population proportion is given by :-
Hence, the confidence interval for the population proportion with a 99% confidence level= (0.143, 0.257)
