25% or 1/4 because 5 is 25 percent of 20 and if you change 25% into a decimal you get .25 which is equivalent to 1/4

Answer:

7/10

Step-by-step explanation:

20 balls.

10 even, 10 odd.

4 numbers less than 5.

That is 14/20 --> 7/10

Most likely.

Tom plants 3 seeds.
Rasek [7]

Answer:

A. 64/125

B. 124/125.

Step-by-step explanation:

A).  As the events ( germinate or not germinate) are independent we multiply the probabilities.

Prob(All seeds germinate) = 4/5*4/5*4/5 =  64/125.

B). Probability of at least one germinating =  1 - probability that none germinate

Probability of  1 seed not germinating = 1 -45 = 1/5.

So Prob(at least one germinating)

= 1 - (1/5 * 1/5 * 1/5)

= 1 - 1/125

= 124/125.

Find the equation of the line that has a slope of 3 and passes through (-1, 2)
Nadusha1986 [10]

Answer:

y= 3x+5

Step-by-step explanation:

start with the linear equation formula

y= mx+b

indentify what you already have.

x= -1 and y= 2 and m(slope)= 3

We are solving for b, so plug in what you have.

2= 3(-1)+b

Simplify.

2= -3+b

Add 3 on both sides.

5= b

Rewrite your equation with the x and y values.

y= 3x+5

The lifespan of a guinea pig is 6 years less than that of a giraffe. The lifespan of a tiger is 4 times that of the guinea pig.
faust18 [17]
Guinea pig (p) = 4 years old
Giraffe (g) = 10 years old
Tiger (t) = 16 years old

P = g-6
T = 4p

30 = g+g-6+(4(g-6))
30 = 2g-6+4g-24
30 = 6g-30
+30 +30
60 = 6g
6 6
10 = g

P = 10-6
P = 4

T = 4(4)
T = 16
