Answer: 12/17

Step-by-step explanation:

This is an example of probability with replacement

n(red) = 3

n(green) = 4

n(blue) = 3

n(speckled) = 3

n(yellow) = 4

Total = 17

The probability of getting a green = number of green / total number

That is

p(green) = 4/17

Also

p(red) = 3/17

" and " in probability means multiplication , therefore:

the probability of getting a green and then a red will be

4/17 x 3/17 = 12/17

PLEASE HELP!

Answer:

See below

Step-by-step explanation:

Use the formulae directly

For a cone, with base radius = r and height = h, here are the related formula

$\textrm{Slant height l} = \sqrt{r^2 + h^2}$ (1)

$\textrm{Lateral surface area} = \pi r l$

$\textrm {Base area} = \pi r^2$

$\textrm { Total Surface Area SA} = \textrm{Base Area + Lateral Area} = \pi r^2 + \pi rl = \pi r(r + l)$ (2)

$\textrm{Volume V = } (1/3) \pi r^2h$ (3)

Therefore directly plugging in the numbers in the above equations:

Note:

l = slant height in cm
SA = total surface area in sqcm
V = Volume in cubic cm

Figure(a)

r = 4, h = 8

$\textrm{l} = \sqrt{4^2 + 8^2} =\sqrt{80} = 8.944 \\\textrm{SA} = 4\pi(4 + 8.944) = 4\pi(12.944) = 162.66\\\textrm{V} = (1/3)\pi(4^2)(8) = 134.04$

Figure(b)

r = 7, h =15

$\textrm{l} = \sqrt{7^2 + 15^2} =\sqrt{274} = 16.55$

$\textrm{SA} = 7\pi(7 + 16.55) = 517.89$

Figure (c)

r = 5, l = 8

$h = \sqrt{l^2 - r^2} = \sqrt{8^2 - 5^2} = \sqrt{39} = 6.245\\SA = \textrm{SA} = 5\pi(5 + 8) = 204.2\\V = (1/3)\pi(5^2)(6.245) = 163.5$

Select the equation that is in slope-intercept form A y+1=5x-2 B y=-2x+15 C 3x=-4y+9 D -5x+3y=6

inysia [295]

Slope intercept form looks like:

y = mx + b

-------------------------------------------------------------------------------------------------------------------

Choose the one that follows the formula

B) y=-2x+15 is your answer.

-2 = m

15 = b

-------------------------------------------------------------------------------------------------------------------

Answer:

Step-by-step explanation:

AB is parallel to CD. So, <ABC = <BCD.

Now, <BCD = <ABC = 180 - 111 - 31 = 38
