Of the 85% of the students in a class who studied for a test,75% passed the test.Of the 15% of the students who didn't study,30%

galina1969 [7]

Probability works for any given number, so we will assume there are 100 students. Of those 100, 85 of them studied. Since 75% of 85 students passed, we will multiply 85 by 0.75. This gives us 60. So of the students who studied, 60 of them passed. Of the 15 students that didn’t study, 30 percent passed. So we multiply 15 by 0.3. This gives us 4.5 students. Add up 60 and 4.5, and you get 64.5. The probability of passing is 64.5%. If you want to round up, it would be 65%. If you want to round down, it would be 64%. But the most precise answer is 64.5%.

A square wall is covered with sqare tiles. There are 85 tiles altogether along the two diagonals. How many tiles are there on th

olchik [2.2K]

Answer:

There are 1849 tiles on the whole wall.

Step-by-step explanation:

If there are 85 tiles along the two diagonals, we can use the following rule:

$\frac{85+1}{2}=43$

So we have 43 tiles in the first diagonal and 85-43 = 42 in the second diagonal.

Now, as we have a square the side will have 43 tiles so the total area will be cover with:

$A=43*43=1849$

Therefore, there are 1849 tiles on the whole wall.

I hope it helps you!

A lighthouse keeper has a 10 degrees angle of depression between the horizontal light beam and the line of sight from the ship.

Andrei [34K]

107.75m
This is a trigonometric ratio problem. the angle of depression (10) is opposite the height (19m) and the distance is adjacent to the distance (x). opposite ad adjacent sides to the angle is a tangent problem.
$tan \theta = \frac{opp}{adj}$
plus in values, we know.
$tan (10) = \frac{19}{x}$
switch tan(10) and x using the products property.
$x = \frac{19}{tan (10)}$
plug in to calulator to get answer
x=107.75
