Answer:
A
Step-by-step explanation:
the volume of a sphere (= a ball) =
4/3 × pi × r³
r (radius) is half of the diameter = 8.8/2 = 4.4 in
so, one ball has a volume of
4/3 × pi × (4.4)³ = 4/3 × pi × 85,184 = 113.5786667...×pi
6 balls are 6 times
113.5786667... × pi × 6 = 681.472...×pi in³
Let’s assume the point in the centre is the origin of the circle.
This means the radius is 21/2 = 10.5cm.
180 - 168 = 12 degrees as the angle between BC.
Circumference of a sector is:
Angle/360 • pi • diameter
=12/360 • pi • 21 cm
= 2.19 cm = 2.20 cm
Which is option B
The given triangle is an obtuse triangle. Option C is correct.
<h3>What is angle measurement?</h3>
An angle measure is the measurement of the angle created by two rays or arms at a shared vertex in geometry.
Angle less ess than 90-degree angles is considered acute. The right angle is 90 degrees. Angles that are obtuse are more than 90 degrees.
The acute, obtuse angles are 36⁰,132⁰ and none of the angles is the right angle.
The given triangle is an obtuse triangle.
Hence, option C is correct.

Step-by-step explanation:
Dada la siguiente información:
y = 20.000 + 1.500x
Siendo:
y= costo total
x= kilometros recorridos
<u>Entonces, si recorrio 20km:</u>
y= 20.000 + 1.500*20
y= $50.000
<u>Ahora, si pago $140.000, cuantos km recorrio:</u>
140.000= 20.000 + 1.500*x
120.000/1.500= x
x= 80km
Answer:
a. z-score for the number of sags for this transformer is ≈ 1.57 . The number of sags found in this transformer is within the highest 6% of the number of sags found in the transformers.
b. z-score for the number of swells for this transformer is ≈ -3.36. The number of swells found in the transformer is extremely low and within the lowest 1%
Step-by-step explanation:
z score of sags and swells of a randomly selected transformer can be calculated using the equation
z=
where
- X is the number of sags/swells found
- M is the mean number of sags/swells
- s is the standard deviation
z-score for the number of sags for this transformer is:
z=
≈ 1.57
the number of sags found in the transformer is within the highest 6% of the number of sags found in the transformers.
z-score for the number of swells for this transformer is:
z=
≈ -3.36
the number of swells found in the transformer is extremely low and within the lowest 1%
