In throwing a dice, there are 6 possible outcomes, namely 1, 2, 3, 4, 5 and 6.
P=(no. of favourable outcomes)/(no. of possible outcomes)
When we multiply the probability of an event with no. of trials, the we get the expected frequency of that event.
1) P(getting 1)=1/6
expected frequency of getting 1
=P(getting)1)×no. of trials
=1/6×600=100
But it is given that one is scored 200 times, so it makes a large difference from expected frequency, which is 100.
Therefore, the dice is not fair.
2) P(getting a tail)=0.3
estimate for the number of times the coin will land on a tail
=expected frequency of getting a tail
=P(getting a tail)×no. of trials
=0.3×150=45
3)P(getting a six)=2/3
expected frequency of getting a six
=P(getting a six)×no. of trials
=2/3×300=200
4)P(getting a three)=0.5
expected frequency of getting a three
=P(getting a three)×350
=0.5×350=175

Answer:
154
113.04 in
Step-by-step explanation:
Area of a circle = Tr²
Circumference of a circle = 2Tr
T = 3.14
r = radius
The radius has to be determined to calculate the area of the circle
43.96 in = 2 x r x 3.14
r = 43.96 in / 2 x 3.14
= 7 in
Area = 3.14 x 7² = 153.86 in = 154 in²

Answers
Answer: 72
Step-by-step explanation:
Answer:
72
Step-by-step explanation:
Circumference of a circle = 2πr
Area of a circle: πr^2
Plug in:
C = 2πr
30.1 = 2(3.14)r
30.1 = 6.28r
r = 4.79 (Dividing both sides by 6.28)
Use area of the circle:
A = 3.14(4.79)^2
= 72.044474
Round to nearest whole number = 72

A company makes steel rods shaped like cylinders. Each rod has a radius of 3 centimeters and a height of 20 centimeters. If the company used 45,781.2 of steel, how many rods did it make?
Answers
Answer:
80 rods of steel.
Step-by-step explanation:
Here is the complete question
A company makes steel rods shaped like cylinders. Each rod has a radius of 3 centimeters and a height of 20 centimeters. If the company used 45,781.2 cm³ of steel, how many rods did it make?
Solution
Since the steel rod is a cylinder whose volume, V = πr²h where r = radius of cylinder = 3 cm and h = height of cylinder = 20 cm.
We substitute these into V to find the volume of one rod.
So, V = πr²h
= π(3 cm)² × 20 cm
= π × 9 cm² × 20 cm
= 180π cm³
= 565.49 cm³
Since 45,781.2 cm³ of steel was used, this total volume of steel, V' equals the number of rods, n times the volume of one rod, V.
So, V' = nV
Making n subject of the formula, we have
n = V'/V
Substituting V' and V into the equation, we have
n = 45,781.2 cm³/565.49 cm³
n = 80.96
We round n = 80.96 down to 80 since we cannot have a decimal number of rods.
So, n = 80 rods
So, the company made are 80 rods of steel.

In triangle EFG, the measure of angle E is 97 degrees, and the measure of angle F is 15 degrees. What is the measure of angle G?
Answers
Answer:
Measure of angle G is 68°.
Step-by-step explanation:
In triangle EFG,
Measure of angle E = 97°
Measure of angle F = 15°
By the triangle sum theorem,
Sum of measures of all interior angles of triangle = 180°
m(∠E) + m(∠F) + m(∠G) = 180°
97° + 15° + m(∠G) = 180°
m(∠G) = 180° - 112°
= 68°
Therefore, measure of angle G is 68°.

Using relations in a right triangle, it is found that the distance between Q and T is given by:
[tex]h = 32\sqrt{2}[/tex]
What are the relations in a right triangle?The relations in a right triangle are given as follows:
The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.Researching the problem on the internet, it is found that:
The side opposite to the angle of 45º is of 32 feet.The hypotenuse is the distance between P and Q.Hence:
[tex]\sin{45^\circ} = \frac{32}{h}[/tex]
[tex]\frac{\sqrt{2}}{2} = \frac{32}{h}[/tex]
[tex]h = \frac{64}{\sqrt{2}} \times \frac{\sqrt{2}}{\sqrt{2}}[/tex]
[tex]h = 32\sqrt{2}[/tex]

1. Area of two small triangles (OR one big) + Area of rectangle
2. Triangle
A(t) = 4*10 = 40 [4*10/2 + 4*10/2]
3. Rectangle
A(r) = 20*10 = 200
4. Combined Area
40+200=240
Step-by-step explanation:
So this figure has two parts:- A triangle and a rectangle
We can first solve area of Triangle
[tex] = \frac{1}{2} bh[/tex]
So the base is 20 and height is 4
[tex] \frac{1}{2} \times 20 \times 4 \\ = 10 \times 4 \\ = 40[/tex]
Now the area of rectangle
[tex] = l \times b[/tex]
Length is 20 and breadth is 10
[tex]l \times b \\ 20 \times 10 \\ = 200[/tex]
So the total area is 200 + 40 which is equal to 240
