Answers

The probability that students who were randomly selected studied for the test, if they pass it with a B or higher grade is: D. 0.80.

How to calculate the probability?

In this exercise, you're required to determine the probability that students who were randomly selected studied for the test, if they pass it with a B or higher grade. Thus, we would apply Bayes's theorem.

Let S represent studied for.Let B represent a score of B or higher grade

Therefore, we need to find P(S|B):

[tex]S|B = \frac{B|S \times S}{B|S \times S\; +\; B|S' \times S'} \\\\S|B = \frac{0.55 \times 0.6}{0.55 \times 0.6 \;+ \;0.2 \times 0.4}\\\\S|B =\frac{0.33}{0.33 + 0.08} \\\\S|B =\frac{0.33}{0.41}[/tex]

Given, n quartz is 1.46 and n water is 1.33.

Putting the value in the equation

Altitudes $\overline{ad}$ and $\overline{be}$ of acute triangle $abc$ intersect at point $h$. if $\angle ahb = 128^\circ$ and $\angle bah = 28^\circ$, then what is $\angle hca$ in degrees?

Answers

The Angle HCA is equal to 52°. This is arrived at using the knowledge of the Total value of Angles in a Triangle and the Total Value of Angles in a Polygon.

What other principles were used to arrive at the answer?

The other principles of mathematics that were used to arrive at the above answer are:

Total Angles on a straight line; Total Angles on a point; and Line segments.

What are the Steps to the Solution?

Step 1 - Recall that we have been given Angles AHB and BAH to be 128° and 28° respectively.

We also know that:

The sum of angles in a triangle is 180°;...................AThe sum of angles on a straight line is 180°;.........BThe sum of angles in a polygon is 360°; while.....CThe total sum of angles at a point is 360°.............D

Since A...therefore:

When ∠AHB (128°) and ∠BAH are taken from 180° we have DBA = ∠28°.

By observation, we can deduce that ∠BDE, ∠CDH, ∠CEH and ∠AEH are all right-angled triangles.


Using the above, we are able to repeat this process of solving for each angle until we have ∠HCA.

To verify that our answer is correct, recall that sum of angles in a polygon is 360°

That means:

∠BDA + ∠DHE + ∠CEH + ∠HCA = 360°

That is, 90+ 128 + 90 + 52 = 360°

Initially, a ball has an angular velocity of 5.0 rad/s counterclockwise. sometime later, after rotating through a total angle of 5.5 radians, the ball has an angular velocity of 1.5 rad/s clockwise. what is the angular acceleration?

Answers

Explanation:

it is not necessary to know for this question, but FYI

1 rad = 180/pi = 57.29577951...°

in essence it describes the arc angle of the arc with the length = radius.

anyway,

we are only dealing with relative sizes here all expressed in radians.

the original spin rate or angular velocity is 5.0 rad/sec.

that means in 1 second it spins by 5 radians (a point on the surface moves by that many degrees).

remember, acceleration is speed/time or distance/time².

then we measure again - after the ball moved by a total angle of 5.5 radians. so, it was longer than 1 second.

so, how much time passed ?

time = distance / speed

5.5 rad / 5.0 rad /1 sec = 1 sec × 5.5 rad / 1×5.0 rad =

= 5.5 sec / 5.0 = 1.1 sec

so, the acceleration was

1.5 - 5.0 = -3.5 rad/(1.1 sec)² = -3.5 rad / 1.21 sec² =

= -2.892561983... rad/sec²

If a concession owner pays $0.50 per pretzel, and it costs the owner $1.00 to have the pretzel prepared and served, what should the owner charge per pretzel if he wants cost to be 60% of the price?

Answers

The owner should charge an amount of $2.50 per pretzel, if the cost price of 60% is desired.

What is cost price?

The cost borne by a producer to manufacture or produce such goods and sell them at a higher price is known as the cost price. In this case, the cost price if $1.50 per pretzel.

If such cost price is desired to be 60% of the selling price, then the selling price will be,

[tex]\rm Sell\ Price= \dfrac{Cost\ Price}{Desired\ Percentage}\ x\ 100\\\\\rm Sell\ Price= \dfrac{1.50}{60}\ x\ 100\\\\\rm Sell\ Price= \$2.5[/tex]
