Jerry has taken a random sample of students and determined the number of electives that each student in his sample took last yea

loris [4]

The sample proportion of the the students that took fewer than the mean number of electives is given by the number of people who took less that the mean number of electives (i.e. 7.63) divided by the total number of students in the sample (i.e. 19). The total number of people who took less than 7.63 electives is 10. Therefore, the required sample proportion is 10 / 19.

Simplify the problem: Sin theta Sec Theta

kherson [118]

Answer:

$\tan \theta$

Step-by-step explanation:

We have to simplify the following expression as given by

$\sin \theta \times \sec \theta$

= $\frac{\sin \theta}{\cos \theta}$

= $\tan \theta$ ( Answer )

Because, we know that $\sec \theta =\frac{1}{\cos \theta}$ and $\tan \theta = \frac{\sin \theta}{\cos \theta}$

If we consider $\sin \theta = \frac{Perpendicular}{Hypotenuse}$ and $\sec \theta = \frac{Hypotenuse}{Base}$ ,

then $\sin \theta \times \sec \theta = \frac{Perpendicular}{Hypotenuse}\times \frac{Hypotenuse}{Base} = \frac{Perpendicular}{Base}= \tan \theta$

What is the square root of 75 to the nearest integer

kodGreya [7K]

<u><em>5√3 is the correct answer.</em></u> First you had to find the prime factorization of 75, and it gave us, $3*5^2=5*5=25*3=75$ , or $=\sqrt{5^2*3}$ . Then you can use apply radical rule, and it gave us, $\sqrt{3} \sqrt{5^2}$ , or $\sqrt{5^2}=5$ , and it gave us the answer is 5√3 is the correct answer. Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie
