Answer:
Step-by-step explanation:
The probability of flipping at least 1 head from flipping 2 coins is:
=> Total sides of the coins = 4
=> Sides which are head = 2
=> Probability = 2/4 = 1/2
Answer:
y = 4.625
Step-by-step explanation:
Subtract 16.4 from both sides and collect terms.
8.4 -6.8 -16.4 = -3.2y +16.4 -16.4
-14.8 = -3.2y
Divide both sides by -3.2.
-14.8/-3.2 = (-3.2y)/-3.2
4.625 = y
The solution is y = 4.625.

Solve:
-Chetan K
Answer:
1. (3x²y³z)²=9x⁴y⁶z²
2. (2m³n⁻⁴)³=8m⁹n⁻¹²
Step-by-step explanation:
Both questions require knowledge of two rules of indices/powers:
(xy)ᵃ=xᵃyᵃ (when numbers multiplied by each other are put to a power, that is equal to the product of each number to that power)
(xᵃ)ᵇ=xᵃᵇ (when a number to a power is put to another power, that is equal to the number to the power of the product of the powers)
1.
(3x²y³z)²
=(3²)(x²)²(y³)²(z²)
=(9)(x²⁽²⁾)(y³⁽²⁾)(z²)
=9x⁴y⁶z²
2.
(2m³n⁻⁴)³
=(2³)(m³)³(n⁻⁴)³
=(8)(m³⁽³⁾)(n⁻⁴⁽³⁾)
=8m⁹n⁻¹²
Hope this helps! :D
It is A) strong positive, because the slope is graphing up
