What is the probability that a randomly selected student has a cell phone and is from School B?
(Round to the nearest hundredth)
a. 0.21
b. 0.41
c. 0.62
Answers
Answer:
B
Step-by-step explanation:
Because there is 1000 people in total, the percentage of people in the school B with cellphones would be solved by finding 408/1000=.408. If you round .408 to the nearest hundredth, because the thousandth place is 8, it would round up to .41
Answer:
[tex]\huge\boxed{\text{(B)}\ 0.41}[/tex]
Step-by-step explanation:
This table will prove to be helpful to find the probability that a student has a cell phone and is from School B.
First off, we know that a total of 1000 students were interviewed, both from School A and from School B.
We also know that 479 of those 1000 were from School B (total on the right).
Looking further into School B, we can see that 408 students from school B have a cell phone.
Therefore, we can find the probability by finding 408 / 1000.
[tex]408 \div 1000 = 0.408 \approx 0.41[/tex]
Therefore, the probability that a randomly selected student is from School B and has a phone is 0.41, or 41%.
Hope this helped!

A cylinderical container of height 28cm and diameter 18cm is filled with water. The water is then poured into another container with a rectangular base 27cm and width 11cm. Calculate the depth of the water in the container ( take π=22/7)
Answers
Answer:
h = 24 cm
Step-by-step explanation:
volume of water in the cylinder = volume of water in the rectangular base container
But ,
volume of cylinder = [tex]\pi[/tex][tex]r^{2}[/tex]h
where: is the radius and h is the height.
volume of cuboid = length x width x height
= l x w x h
So that;
[tex]\pi[/tex][tex]r^{2}[/tex]h = l x w x h
But, r = [tex]\frac{diameter}{2}[/tex] = [tex]\frac{18}{2}[/tex] = 9 cm, height of cylinder = 28 cm, length = 27 cm, width = 11 cm, [tex]\pi[/tex] = [tex]\frac{22}{7}[/tex].
Thus,
[tex]\frac{22}{7}[/tex] x [tex](9)^{2}[/tex] x 28 = 27 x 11 x h
[tex]\frac{22}{7}[/tex] x 81 x 28 = 27 x 11 x h
7128 = 297h
h = [tex]\frac{7128}{297}[/tex]
= 24
h = 24 cm
The depth of the water in the container is 24 cm.

Mel spent $47.97 on three cds. Two of the cds were the same price, and the third cd cost $5.00 more than one of the other two cds. The total cost can be represented by the equation 2c + (c+5) = 43.97, where c is the cost of one lower-priced cd. What was the cost of the higher priced cd?
Answers
Given :
The total cost can be represented by the equation 2c + (c+5) = 43.97, where c is the cost of one lower-priced cd.
To Find :
The cost of the higher priced cd.
Solution :
Solving given equation :
2c + c + 5 = 43.97
3c + 5 = 43.97
3c = 43.97 - 5
3c = 38.97
c = $12.99
Therefore, cost of higher priced cd is $( 12.99 + 5 ) = $17.99 .
Hence, this is the required solution.

A person is standing 40 ft from a light post and can see the top of the light at a 35∘ angle of elevation. The person’s eye level is 5
feet from the ground. What is the height of the light post to the nearest foot.
The height of the light post is____ feet?
Answers
Answer:
Height of light post = 33 feet
Step-by-step explanation:
We will use the trigonometric ratios to find the height of light post
The given scenario forms a right angled triangle with the right angle with the light post.
The distance between light post and the person is the base.
So, base = b = 40 feet
The height of light post will be the perpendicular
So,
Perpendicular = p = x
Angle = 35°
So,
tan (angle) = p/b
tan 35° = p/40
0.7002 =p/40
0.7002*40 = p
p = 28 feet
Since the persons eye level is 5 feet from the ground, 5 feet will be added to perpendicular for actual height of light post.
Height of light post = 28+5 = 33 feet ..
Find the equation of the line shown.
Answers
Answer:
y = 2x
Step-by-step explanation:
By inspection, we can see the line crossing through the points: (0,0) , (1,2)
[Use the slope formula to find m]
m = (Y2 - Y1) / (X2 - X1)
m = (2 - 0) / (1 - 0)
m = 2/1 = 2
[Use the point slope formula to find equation]
(y-y0) = m(x-x0)
y - 0 = 2(x - 0)
y = 2x
It should be the below, because when you take rise over run, you get 2 as a slope, there is no y-intercept because if you substitute in a value of x, x does not have and “remainders”.
Y = 2x

State the median.
Answers
Answer:
-3.5
Step-by-step explanation:First you need to order the numbers so the numbers ordered would be -20,-16,-10-,10-,7,0,1,2,5,8 the median is finding the middle number in a list so you would cross of the end numbers until you are left -7 and 0 you then find the mid point of these two numbers which is -3.5 so that would be the answer.
Answer:
The median is -3.5
Step-by-step explanation:
hope this helps
-16, -20, -10, 1, -10, 5, 0 ,8 ,2 ,-7
Arrange the number in numerical order.
-20,-16,-10,-10,-7,0,1,2,5,8
There's two number is the middle which is -7 and 0 all you have to do is add them together and divide by 2.

When converting a decimal to a fraction, the digits to the right of the decimal point become the _____
of the fraction.
Answers
Answer:
numerator
Step-by-step explanation:
it becomes the numerator because however many places over the numbers to the decimals are is the amount if its in like the 10th 100th 1000th and so on. But if there is a one or more to the left side of the decimal it becomes the whole number, so that leaves the numerator. So that is how the numerator is the answer.

Let u = ⟨–2, 6⟩, v = ⟨3, 2⟩, and w = ⟨–1, 4⟩. What is the magnitude and direction angle of 2(u + v) – 3w?
2.8; θ = 45.0°
6.4; θ = 38.7°
28.0; θ = 92.0°
41.0; θ = 51.3°
Answers
u = ⟨-2, 6⟩
v = ⟨3, 2⟩
w = ⟨-1, 4⟩
u + v = ⟨-2, 6⟩ + ⟨3, 2⟩
u + v = ⟨-2 + 3, 6 + 2⟩
u + v = ⟨1, 8⟩
2 (u + v) = 2 ⟨-1, 8⟩
2 (u + v) = ⟨2 • 1, 2 • 8⟩
2 (u + v) = ⟨2, 16⟩
-3 w = -3 ⟨-1, 4⟩
-3 w = ⟨-3 • (-1), -3 • 4⟩
-3 w = ⟨3, -12⟩
2 (u + v) - 3 w = 2 (u + v) + (-3 w)
2 (u + v) - 3 w = ⟨2, 16⟩ + ⟨3, -12⟩
2 (u + v) - 3 w = ⟨2 + 3, 16 + (-12)⟩
2 (u + v) - 3 w = ⟨5, 4⟩
Then the magnitude of this vector is
||2 (u + v) - 3 w|| = √(5² + 4²) = √41 ≈ 6.403
so the second choice is correct.
