There are 82 boats in the navy. 48 of them are battleships and the rest are destroyers. What is the ratio of the number of destroyers to the number of battleships?
Let
x -----> the number of destroyers
y ----> the number of battleships
the ratio is
x/y
we have
y=48
x=82-48=34
therefore
ratio=34/48
simplify
34/48=17/24
answer is 17/24 or 17:24
Answer:
95% confidence interval for p, the population proportion of students whose parents bought a car for them when they left for college
(0.4958 , 0.7041)
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the sample size 'n' = 85
The sample proportion
95% confidence interval for p, the population proportion of students whose parents bought a car for them when they left for college
<u><em>Step(ii):-</em></u>
Given that the level of significance
α = 0.05
Z₀.₀₅ = 1.96
(0.6 - 0.104138 , 0.6 +0.104138)
(0.4958 , 0.7041)
<u><em>Final answer:-</em></u>
95% confidence interval for p, the population proportion of students whose parents bought a car for them when they left for college
(0.4958 , 0.7041)

This is a 30° 60° 90° triangle, so the rules below apply:
x is the short leg of the triangle, located across from the 30° angle. (In this problem, the short leg is labled b)
The hypotenuse leg is across from the right angle, and is always 2x (In this problem, the hypotenuse leg is labled c)
The long leg of the triangle is located across the 60° angle and is always x√3. (in this problem, the long leg is labeled a)
Answer:
f(10) = - 26
Step-by-step explanation:
To evaluate f(10), substitute x = 10 into f(x), that is
f(10) = 4 - 3(10) = 4 - 30 = - 26
