Give the equation of the line through the point ( – 15, - 1) with a slope of -3/5 in slope -intercept form

shutvik [7]

Answer:

-1 = (-3/5)-15 + b

(I don't know the y-intercept bc I don't have a graphing calc but to find it out you just graph it and then see where the line passes thru the y axis)

If (1)=3 and f(n)=f(n-1)-1 then find the value of f(6)

katrin [286]

Answer:

f(1) = 3

f(n) = f(n-1) - 1

Otherwise,

f(n) = f(1) - (n-1)

=> f(6) = 3 - 5 = -2

Hope this helps!

Out of 16 spins, a purple-and-red spinner landed on purple 9 times and on red 7 times. Based on experimental probability, how ma

Diano4ka-milaya [45]

Answer:

Option A.

Step-by-step explanation:

It is given that out of 16 spins, a purple-and-red spinner landed on purple 9 times and on red 7 times..

Experimental probabilities are

$P(Purple)=\dfrac{Purple}{Total}=\dfrac{9}{16}$

$P(Red)=\dfrac{Red}{Total}=\dfrac{7}{16}$

Based on experimental probability, we need to find how many of the next 64 spins would we expect on land on red.

The expected number of red in 64 spins is

$\text{Expected red}=64\times P(Red)$

$\text{Expected red}=64\times \dfrac{7}{16}$

$\text{Expected red}=28$

Therefore, the correct option is A.
