Hope this helps
Pls mark brainliest
256 * 40 = 10,240 cm needed
so if the balls are 30 cm each then
10, 240 divided by 30 = 341.3
so the teacher will need 342 balls.
This is what I got when I did the work out on paper
Answer:
about 54% of the people surveyed were females
Step-by-step explanation:
to calculate the % of females out of everyone, you need to add everyone up, and then add up only the females.
119+150+447+735+1174+103+171+512+710+756=4877
4877 is the Total number of people surveyed
119+150+447+735+1174=2625
2625 is the total number of females surveyed
so
to convert 2625/4877 to a %, first turn it into a decimal
2625/4877=0.538
now multiply 0.538 by 100
0.538*100=53.8%
so about 54% of the people surveyed were females
Answer:
a. p`± z₀.₀₂₅
b.0.6 ± 1.96
c. { -1.96 ≤ p`± z₀.₀₂₅ ≥ 1.96} = 0.95
Step-by-step explanation:
Here the total number of trials is n= 1000
The number of successes is p` = 600/1000 = 0.6. The q` is 1 - p`= 1- 0.6 = 0.4
The degree of confidence is 95 % therefore z₀.₀₂₅ = 1.96 ( α/2 = 0.025)
a. The formula used will be
p`± z₀.₀₂₅ ( z with the base alpha by 2 (α/2 = 0.025))
b. Putting the values
0.6 ± 1.96
c. Confidence Interval in Interval Notation.
{ -1.96 ≤ p`± z₀.₀₂₅ ≥ 1.96} = 0.95
{ -z( base alpha by 2) ≤ p`± z₀.₀₂₅ ≥ z( base alpha by 2) } = 1- α
