What is the point slope for of the line with. Slope 2/5 that passes through the point (-4,-7)

WITCHER [35]

The point-slope form of a line:

$y-y_0=m(x-x_0)$

We have:

$m=\dfrac{2}{5}\\\\(-4,\ -7)\to x_0=-4,\ y_0=-7$

Substitute:

$y-(-7)=\dfrac{2}{5}(x-(-4))\\\\y+7=\dfrac{2}{5}(x+4)$

Answer:

Step-by-step explanation:

Part A: 5/26

Part B: 5/26+ 1/2 which is 18/26 or 9/13

Part C: 5/26 +21/25. 'without replacing' means there is one less option in the bag. So denominator becomes 26-1=25. Numerator is 21 because there are a total of 21 consonants in the alphabet. Since we removed a vowel and not a consonant, it will remain 21.

you decided to keep flipping a coin until tails came up. what is the probability of tails coming up on the 5th flip of the coin?

zzz [600]

1 in 2. Each flip is independent of each other, so whether it is the 1st flip or 5th or 100th, the probability of getting tails on any one flip is 50%
