A line is passing through (7,-3) and it’s slope is -1/2, white the equation in point slope form
Crank

Equation of the line in point slope form is y + 3 = -1/2(x - 7)

Step-by-step explanation:

  • Step 1: Given slope of the line is -1/2 and passes through the point (x1, y1) = (7, -3). Equation in point slope form is y - y1 = m(x - x1)

⇒ y - (-3) = -1/2(x - 7)

⇒ y + 3 = -1/2(x - 7)

A box contains 2 dozen pairs of contact lenses ,of which 8 pairs are tinted. A pair of contact lenses is drawn at random from th
tia_tia [17]

Answer:

\dfrac{2}{3}.

Step-by-step explanation:

It is given that a box contains 2 dozen pairs of contact lenses ,of which 8 pairs are tinted.

1 dozen = 12 units

Total pairs of contact lenses =2\times 12 = 24

Tinted pairs of contact lenses = 8

Pairs of contact lenses not tinted = 24 - 8 = 16

If a pair of contact lenses is drawn at random from the box, then we need to find the probability that it is not tinted.

P(\text{Not tinted})=\dfrac{\text{Pairs of contact lenses not tinted}}{\text{Total pairs of contact lenses}}

P(\text{Not tinted})=\dfrac{16}{24}

P(\text{Not tinted})=\dfrac{2}{3}

Therefore, the required probability is \dfrac{2}{3}.
