Probability of green= # of green marbles ÷ total # of marbles
                               
                              =  6 ÷ (6 + 9)
                             
                              = 0.4  OR  \frac{2}{5}

Paul [167]

Answer: A

Step-by-step explanation: $88.74÷9=$9.86

$88.74 is the total amount

9 players, and each player has to pay the same amount

we have to divide it evenly in 9 pieces, so we divide $88.74 into 9 groups which then equals $9.86

Graph the function f(x) = x3 – 3x – 2. Based on the graph, which value for x is a double root of this function?
Lana71 [14]

Answer:

The value of x = - 1 and 2 double root of this function

Step-by-step explanation:

we need to find the value of x which double root of f(x)=x^{3} -3x-2

If we replace x with -2 then

f(-2)=(-2)^{3} -3(-2)-2 = -8+6-2 =-4

If we replace x with -1 then

f(-1)=(-1)^{3} -3(-1)-2 = -1+3-2 =0

If we replace x with 1 then

f(1)=(1)^{3} -3(1)-2 = 1-3-2 =-4

If we replace x with 2 then

f(2)=(2)^{3} -3(2)-2 = 8-6-2 =0

Hence, the value of x = - 1 and 2 double root of this function

In a science experiment, Shelly has to weigh a compound in grams. The balance in her school measures in milligrams (mg). Shelly
Oksi-84 [34.3K]
We know, 1 g = 1000 mg
so, 1 mg = 1/1000 g
then, 8,450 mg = 1/1000 * 8,450 = 8.450 g

In short, Your Answer would be: 8.450 Grams

Hope this helps!

Lelia says that 75% of a number will always be greater than 50% of a number. Complete the inequality to support Lelia's claim an
worty [1.4K]

Answer:

Let 'x' and 'y' be two different numbers.

Leila says that 75% of a number will always be greater than 50% of a number. The inequality that represents this statement is the following:

0.75x > 0.5y

Let x = 100 and y=200. We have that:

0.75(100) > 0.5(200)

75 > 100 ❌ INCORRECT ❌

Given that we found a case in which 75% of a number is not greater than 50% of a number, we can conclude that Leila's claim is incorrect.
