Answer:
C). Circle Graph
Step-by-step explanation:
As per the question, a 'circle graph' would be most adequate to display that the majority of the teenagers prefer to do their study and homework in their bedrooms. A circle graph or pie-chart represents the data in a visually appealing manner using colors to display various proportions of the data that makes it easy to understand for the readers. Thus, more than half of the circle filled with the same color will clearly hint that most of the teenagers love doing their studies in their bedroom. Thus, option C is the correct answer.

You decide to buy a car with a base price of $11,499 at an interest rate of 6.2%. The car will be compounded monthly in those 5 years. What will your monthly payment be? Round the money to the nearest hundredth
Answer:
A = $15,696.72
Step-by-step explanation:
Use the compound amount formula: A = P(1 + r/n)^(nt). Here the number of compounding periods is nt, or (12 per year)(5 years) = 60.
Our formula becomes A = $11,499(1 + 0.062/12)^60, which works out to:
A = $11,499(1 + 0.0052)^60, or
A = $15,696.72
The monthly payment is $15,696.72/60, or $261.61.
A chord is 10cm from the centre of a circle of radius 15cm. Find the length of the chord.
Answer: 21.44 cm
Step-by-step explanation:
Given
Radius r=15 cm
distance of chord from the center is 10 cm
From the figure, the length of the chord is AC
Applying Pythagoras
[tex]\Rightarrow AO^2=OB^2+AB^2\\\Rightarrow AB^2=15^2-10^2\\\Rightarrow AB^2=225-100=115\\\Rightarrow AB=\sqrt{115}=10.72\ cm[/tex]
The length of the chord is [tex]AC=2AB=21.44\ cm[/tex]

A bag contains 3 red marbles, 7 blue marbles and 5 green marbles. If two marbles are
drawn out of the bag, what is the probability, to the nearest 100oth, that both
marbles drawn will be blue?
Answer:
0.218
Step-by-step explanation:
Probability is the likelihood of an event.
According to the word problem, of the 15 marbles, there are 7.
Since there are 7 blue marbles, the expected outcome of both events is 7.
The probability of the first blue marble is 7/15.
The probability of the second blue marble is 7/15.
To find the probability of both marbles being drawn, we must multiply both fractions.
Like this,
7/15 ⋅ 7/15 = 49/225.
49/225 in decimal form is 0.21777778
0.21777778 rounded to the nearest hundredth is 0.218.
Therefore, the probability of two blue marbles being drawn out of the bag is 0.218.
12. 21 and 22 are supplementary. The measure of 1 is three times the measure of 2. What is m2?
a. 30°
b. 45°
c 54
d.55
e. 135
Answer:
The measure of angle 2 is 45 degrees
Step-by-step explanation:
Mathematically, when two angles are supplementary, the sum of these angles will be equal to 180 degrees
Let the measure of angle 2 be x
The measure of angle 1 is 3 times this and that will be 3 * x = 3x
The sum of both will be 180
x + 3x = 180
4x = 180
x = 180/4
x = 45
From a horizontal distance of 80m, the angle of elevation to the top of a flagpole is 180. Calculate the height of the flagpole.
Answer:
0
Step-by-step explanation:
From a horizontal distance of 80m, the angle of elevation to the top of a flagpole is 180. Calculate the height of the flagpole.
We solve the above question using the trigonometric function of Tangent
The formula is given as:
tan θ = Opposite/ Adjacent
θ = 180°
Adjacent = 80m
Opposite = Height = x
Hence,
tan 180 = x/80
Cross Multiply
x = tan 180 × 80
x = 0m
The height of the flag = 0

It can be deduced that the addition of -3 and 4 will be 1.
How to add the numbersIt can be deduced that the addition of -3 and 4 will be;
= -3 + 4

When the winning score in golf is the lowest number, the lowest number is -1.
The value of the expression -273 - (-576) will be:
= -273 - (-576)
= -273 + 576
= 303
Also, -56/4 = -14. The value of the expression (2 - 19) + (-12) will be:
= (2 - 19) + (-12)
= -17 - 12
= -29
The value of -2x = 22 will be:
-2x = 22
Divide both side by -2
-2x/-2 = 22/-2
x = -11
The value of 5 + 3x = -22 will be;
5 + 3x = -22
5x = - 22 - 5
3x = -27
x = -27/3 = -9
5(x + 3) = 35
5x + 15 = 35
5x = 35 - 15
5x = 20.
5x/5 = 20/5
x = 4
