Answer:
Step-by-step explanation:
-Given the boundaries as 0.412 and 0.878
- is the point estimate for the population proportion and is calculated as follows:
#The margin of error, ME can be calculated for the confidence intervals using the formula:
#The number of individuals in the sample is the product of the point estimate and population size:
Hence, there are 645 individuals in the sample.
Answer: The correct answer is B) 21%
Step-by-step explanation:
This is a binomial model probability problem. We need to find the probability of 6 out of 10 new births at a hospital being boys. The information we need is the number of trials observed, the number of successes and the percentage chance you have of any birth being a boy. The number of trials are 10, with the number of successes being 6 (the number of trials we want to be boys) It states that 51% or 0.51 of all births in the US are boys so we can use this value to determine our answer using our binomial model formula. After simplifying we get our answer of 21% I hope this has been of use to you :)
Have a wonderful rest of your day!
To evaluate the radius of the cone we proceed as follows:
V=1/3 πr²h
plugging in the values, v=88π, h=8 ft
step 1
88π1/3πr²(8)
step 2
88π=8/3πr²
step 3
divide both sides by π
88=8/3r²
multiply both sides by 3/(8)
88(3/8)=r²
step 4
simplify
33=r²
step 5
get the square root
r=√33
Thus the mistake that Fatima made was:
<span> In step 3, Fatima did not multiply 88 by the reciprocal of 8/3 </span>
Answer:
her equation should be a² + 3² = 4²
Step-by-step explanation:
a² + 3² = 4²
a² + 9 = 16
a² = 7
a =
a ≈ 2.6 inches
I think this is an inequality problem.
Given:
<span>no-hitter innings is 112 in a season.
currently has 87 no-hitter innings.
</span><span>Let x be the possible number, the sum of x and 87 should be equal to 112 to match the school record or be greater than 112 to break the school record.
x + 87 </span>≥<span> 112
x + 87 - 87 </span>≥ 112 - 87
x ≥ 25
<span>The possible numbers of additional no-hitter innings the team can achieve to match or break the school record in a season are 25 and above.</span>
