The answer is yes. When two events are mutually exclusive, this means that the two events cannot happen at the same time. For example, getting heads and getting tails after flipping a coin are mutually exclusive events because you can’t get heads AND tails in one flip.

For this problem, we can figure this out by considering all the multiples of 5 that are less than or equal to 20: 5, 10, 15, and 20. However, NONE OF THESE ARE PERFECT SQUARES. This means that, when rolling a 20-sided number cube once, it’s impossible to get a number that is both a multiple of 5 AND a perfect square. The least common multiple of 5 that is a perfect square is 25, but this can’t be on the cube.

Hope this helps!

Algebraically determine the zeros of the quadratic function g(x)= x^2+7x+12. Show all work please
Alinara [238K]

Answer:

x = - 4, x = - 3

Step-by-step explanation:

To find the zeros equate f(x) to zero, that is

x² + 7x + 12 = 0

To factorise the quadratic

Consider the factors of the constant term (+ 12) which sum to give the coefficient of the x- term (+ 7)

The factors are + 4 and + 3, since

4 × 3 = 12 and 4 + 3 = 7, hence

(x + 4)(x + 3) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 4 = 0 ⇒ x = - 4

x + 3 = 0 ⇒ x = - 3

Solve for x. Enter the solutions from least to greatest. 6x^2 +1 =487 lesser=x greater=x
jok3333 [9.3K]

Answer:

(-9, 9)

Step-by-step explanation:

6x^{2} +1 = 487                                             (Given)

       -1       -1                                     (Getting "x" alone)

6x^{2}  = 486                                        (Cont. Getting "x" alone)

÷6      ÷6                                                           ↓

x^{2} = 81                                                              ↓

\sqrt{x} ^2 = \sqrt{81}                           (9 and -9 squared are both equal to 81)

↓             ↓                                                        ↓

x = 9      x = -9                                            (Answer)

Hope this Helps! :)

Which of the following is the function representing the graph below?
Elena-2011 [213]
We have that

using a graph tool
see the attached figure 

 case A) <span>f(x) = 4^x
</span>this function is not <span>represented in the graph

case B) </span><span>f(x) = 4^(x) − 3
</span>this function is not represented in the graph

case C) <span>f(x) = 4^(x) + 3
</span>this function is  represented in the graph

case D) <span>f(x) = 4^(x + 3)
</span>this function is not represented in the graph

the answer is
case C) f(x) = 4^(x) + 3

HELP ME PLEASE!!!!!!
V125BC [204]
Let a be aluminum and g be gold and k how many times:

2*10⁻¹mg a+ 6*10¹mg g= 154 lb

so a=kg

k=a/g

k=2*10⁻¹/6*10=1/300

a=1/300g

so Aluminum is 1/300 of gold.

jason is using a 1/3 gallon pitcher to fill an empty 3/4 gallon water jug. how much water will he need to completely fill the wa
Murljashka [212]
Jason will need to use 9 more 1/3 gallon-ful pitchers to fill the rest of the empty 3/4 gallon water jug. You convert the two fractions so they have the same denominator (1/12 and 3/12). Then you add the remaining amount of 1/12's to complete 12/12, or 1.
