Answer:
8x⁵y⁷
Step-by-step explanation:
4x²y³ × 2x³y⁴ = 8x⁵y⁷
Based on the given description above, I have analyzed it and come up with a solution to get the probability if in a random sample of 25 students from this said group and the average height is between 73 and 75 inches. So if you calculate it, it will be like this:
<span>2P(Z<2)−1</span>
To find the probability of Z, use the normal distribution table.
The value for Z being less than 2 is 0.9772.
The final result is then<span><span>2(0.9772)−1=0.9544
Hope this is the answer that you are looking for.</span></span>
Answer:

Step-by-step explanation:
The length of arc AB is 3π given that radius of the circle is 27 units and the angle made by the arc AB at the center of the circle is 20°. This can be obtained using the formula to find arc length.
<h3>Find the length of the arc AB:</h3>
<u>Formula used for finding </u><u>arc length</u><u>:</u>
- If the angle made by the arc at the center of the circle is in degrees, the formula to find the length of the arc is,
⇒ L = 2 π r (θ/360°)
where r is the radius of the circle and θ is the angle made by the arc at the center of the circle.
- If the angle made by the arc at the center of the circle is in radians, the formula to find the length of the arc is,
⇒ L = r × θ
where r is the radius of the circle and θ is the angle made by the arc at the center of the circle.
Here in the question it is given that,
r = 27 units
θ = 20°
Since the angle made by the arc at the center of the circle is in degrees, the formula to find the length of the arc is,
⇒ L = 2 π r (θ/360°)
L = 2 π (27) (20°/360°)
L = π (27) (20°/180°)
⇒ L = 3 π
Hence the length of arc AB is 3 π given that radius of the circle is 27 units and the angle made by the arc AB at the center of the circle is 20°.

Answer:
Step-by-step explanation:
So that " ⋅ " sign is just the multiplication, and always remember:
WHENEVER YOU MULTIPLY TWO NEGATIVE NUMBERS THE PRODUCT IS ALWAYS POSITIVE
So you just multiply 7 and 4 which is 28 and leave it be.
