The key to this problem is to write out the probabilities and determine which one is most likely and least likely (or impossible).

Drawing a black card from a standard deck of playing cards:

There are 52 cards in a playing deck, 26 are red and 26 are black.

\frac{26}{52} = \frac{1}{2}

A spinner has 5 equal sections numbered 1 through 5. You spin and land on a number less than or equal to 4.

This means that all the numbers (1, 2, 3, and 4) except 5.

\frac{4}{5}

You roll a standard number cube and get a number less than 2.

A standard cube is from 1 to 6, and 1 is the only number on the cube that is less than 2.

\frac{1}{6}

You roll two standard number cubes and the sum is 1.

The smallest number on a standard cube is 1, so you can't make the sum 1 with 2 dice.

0

If we put these in order, we get:

\frac{4}{5}, \frac{1}{2}, \frac{1}{6}, 0

So, the order going from top to bottom in the picture is: 2, 1, 3, 4

Round to the nearest tenth wa hit is the perimeter of the triangle
klio [65]

Answer:

D. 11.8 cm

Step-by-step explanation:

This triangle is a 30°-60°-90° triangle. There is a shortcut to find the lengths of the sides of a 30°-60°-90° triangle. The longest side is the hypotenuse. The longest side is double the shortest side or, the shortest side is half the longest side. Here the longest side is 5, so the short leg (shortest side) is 2.5

The other shortcut is that the longer leg is the

short leg×sqroot3

Here, the short leg is 2.5, so the long leg is 2.5×sqroot3

Perimeter is all the sides added together.

5 + 2.5+ 2.5×sqrt3

Do the times first.

5 + 2.5 + 4.3

= 11.8

G<br> What is the value of f(x) when X=-3?<br> f(x)=-2x-3<br> f-3)=
Black_prince [1.1K]

Answer:

f(-3)=3

Step-by-step explanation:

We know that f(x)=-2x-3. In order to find f(-3), we simply need to substitute x with -3.

Thus, we have:

=-2(-3)-3

=6-3

=3

Cory's roses grow around 1 inch each month. When he planted them they were 6 inches tall.
Stella [2.4K]

Answer:

r=12 as answer but as you will have reflective numbers (r12+2)(10x10)=3 in this sort of equation you will see that as they grew at a 88.3% rate 5/6 and 0.16 is a per month rate the coefficient value we can round down and call r12 = 6 for step 2 in the equation. As we can also find +0.88 which rounds to 1 and 0.33 the rate of change per month rounds to -1 and -100/12=8.3 if you are looking for the percentage. To find 6 we only need to 10/10 = 1. It is important you keep an equation simple for the growth as the change in measurement will always need a new percentage and we have a base number that can show such percentage as if it changed to 100% again at 12 inches we could reuse the equation =3-2=1 etc. or r12/100 =0.88 r=rise percentage and also be divided into 2 if we call r12 and r2 in same first equation to make r6.

$500 shared in ratio 2:3:9
RideAnS [48]
2:3:9......added together = 14

2/14 (500) = 1000/14 = 71.43
3/14 (500) = 1500/14 = 107.14
9/14 (500) = 4500/14 = 321.43
