Answer:

The third and fourth one

Step-by-step explanation:

Hii,

When you divide by a negative, the sign flips. In the third and fourth one you're dividing by a negative so the inequality sign flips. For the rest, you're not.

Hope this helps :)

The correct answer is the third and fourth one because it makes the most sense and it’s a closest answer

$y = 2x {}^{2} + e {}^{ - x {}^{4} }$

$\frac{dy}{dx} = 4x +( e {}^{ - x {}^{4} } )( - 4x {}^{3} )$

$\frac{dy}{dx} = 4x - 4x {}^{3} e { }^{ - x {}^{4} }$

$\frac{dy}{dx} = 4x(1 - x {}^{2} e {}^{ - x {}^{4} } )$

$\frac{dy}{dx} = 0 \\ 4x = 0 \: \: \: \: \: 1 - x {}^{2} e {}^{ - x {}^{4} } = 0$

$4x = 0 \\ x = 0 \: \: \: \: \: \: y(0) = 0 + e {}^{0} = 1$

2.10 ÷ 5 = 0.42

It is $0.42 for 100 mL

The average time taken to complete a test follows normal probability distribution with a mean of 70 minutes and a standard devia

Dimas [21]

Under 45 mins is roughly 16%. This is because 68% of the curve exists within 1 SD of the mean. So 16% must be outside and smaller and 16% outside and larger (on average).

It is impossible to determine how likely you are to find someone with exactly the second amount. However, if you are looking for that or less, you would get 84%
