A coin is tossed and a single 6 sided number cube is rolled. Find the probability of landing on the heads side of the coin and r
Delicious77 [7]

Answer:

The probability of landing on the heads side of the coin and rolling 3 on the number cube is 0.083.

Step-by-step explanation:

Given:

Coin is tossed and a single 6 sided number cube is rolled.

Let the event of tossing head be 'H' and event of rolling a 3 be 'R3'.

Now, we know that:

Probability of an event 'A' = Favorable outcomes of 'A' ÷ Total possible outcomes

Now, for tossing a coin, the total possible outcomes are head and tail. So, there are 2 possible outcomes.

So, probability of event 'H' is given as:

P(H)=\dfrac{n(H)}{n(S)}\\\\P(H)=\frac{1}{2}=0.5

Similarly, for rolling a 6 sided cube, the possible outcomes are numbers 1 to 6. So, the number of possible outcomes is, n(S)=6

Now, probability of rolling a 3 is given as:

P(R3)=\frac{n(R3)}{n(S)}\\\\P(R3)=\frac{1}{6}

Now, both the events 'H' and 'R3' occur together. So, the combined probability is the product of two individual probabilities as they are independent events. So,

P(H\ and\ R3)=P(H)\times P(R3)\\\\P(H\ and\ R3)=\frac{1}{2}\times \frac{1}{6}\\\\P(H\ and\ R3)=\frac{1}{12}=0.083

Note: Independent events are those events whose intersection is an empty set of events or the outcome of one event doesn't affect the outcome of the other event.

Therefore, the probability of landing on the heads side of the coin and rolling 3 on the number cube is 0.083.

What are the values of f(x) = 9^x when x= -2? <br><br> a) 1/81<br> b) 81<br> c) 1/18<br> d) 18
Novosadov [1.4K]

Answer:

(a)

Step-by-step explanation:

using the rule of exponents

• a^{-m} ⇔ \frac{1}{a^{m} }, hence

9^{-2} = \frac{1}{9^{2} } = \frac{1}{81} → (a)

X-intercept and y-intercepts og y=x^2-3
Rufina [12.5K]

Answer:

Part 1) The y-intercept is the point (0,-3)

Part 2) The x-intercepts are the points (-\sqrt{3},0)\ and\ (\sqrt{3},0)

Step-by-step explanation:

we have

y=x^{2}-3

This is a vertical parabola open upward

step 1

Find the y-intercept

we know that

The y-intercept is the value of y when the value of x is equal to zero

so

For x=0

y=(0)^{2}-3

y=-3

The y-intercept is the point (0,-3)

step 2

Find the x-intercepts

we know that

The x-intercept is the value of x when the value of y is equal to zero

so

For y=0

x^{2}-3=0

solve for x

Adds 3 both sides

x^{2}-3+3=0+3

x^{2}=3

take square root both sides

x=(+/-)\sqrt{3}

so

The x-intercepts are the points (-\sqrt{3},0)\ and\ (\sqrt{3},0)

Martin thinks of two numbers. he says, "The HCF of my two numbers is 6. The LCM of my two numbers is 15" write down two possible
tigry1 [53]

Answer:

There is no possible answers

Step-by-step explanation:

We are told in the above question that:

"The HCF of my two numbers is 6.

This means the two numbers are factors of 6

"The LCM of my two numbers is 15"

LCM means the lowest common multiple.

This means the two numbers must be have 15 as one of its multiples.

From the above explanation above, there are no two numbers like that
