Mario flips a coin, then rolls a standard six-sided number cube. What is the probability that Mario gets tails and rolls a number greater than 4?

Enter a number in the box.

Answers

Answer 1

Answer:

1/6.

Step-by-step explanation:

Prob(Tail) = 1/2

Prob(gets number > 4 ,  that is a 5 or a 6) = 2/6 = 1/3.

So required probability = 1/2 * 1/3

= 1/6.

The individual probabilities are multiplied as the 2 events are independent.

Answer 2

The probability that Mario gets tails and rolls a number greater than 4 is,

⇒ 1 / 6

What is mean by Probability?

The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

Given that;

Mario flips a coin, then rolls a standard six-sided number cube.

Now, We get;

The probability to get tails is,

⇒ 1 / 2

And, The probability to get a number greater than 4 (5 and 6) is,

⇒ 2 / 6

⇒ 1 / 3

Thus, The probability that Mario gets tails and rolls a number greater than 4 is,

⇒ 1/2 × 1/3

⇒ 1 / 6

Answer:

Points A and B are not on the unit circle.

Step-by-step explanation:

Recall that a "unit circle" has a radius of 1, and so if x² + y² ≠ 1, the point is not on a unit circle.

In A we apply the Pythagorean Theorem as follows:  1² + 1² = 2 ≠ 1.

Therefore, point (1, 1) is not a point on the unit circle.

In B:  if we square the x and y components and add these squares together, we get 3/4 + 1/9, which does not equal 1.  Point not on unit circle.

In C, we get 4/9 and 5/9, which eqals 1.  This point C lies on the unit circle.

In D, we get 0.64 + 0.36 = 1, so this point does lie on the unit circle.

Thus:  not on unit circle:  A(1, 1), B(√3/2, 1/3)

On unit circle:  D(0.8, -0.6), C(-2/3, √5/3)

Sandra is mixing bleach and water so she can clean her house. She has a gallon bottle with a mixture of 60% bleach and 40% water. However, she needs the mixture to be 45.5% water. How much water should be added to the mixture to make it 45.5% water? (Round to the nearest hundredth)

Answers

The amount of water to be added to the mixture to make it 45.5% water is 0.06.

What are word problems?

Word problems in mathematics involve the interpretation of word problems into variables and setting an equation to solve those variables.

From the given information:

The amount of bleach to water = 60% : 40%If she needs the mixture to be 45.5%, the amount of water to be added is:


= (45.5 - 40.0)%

= 5.5%

Approximately 3.5% of all children born in a certain region are from multiple births (that is, twins, triplets, etc.). A random sample of 20 children born in the region will be selected. What is the probability that the sample will have exactly 3 children who are from multiple births

Answers

Answer: Approximately 0.026673

=======================================================

Explanation:

n = 20 is the sample size

p = 0.035 is the probability of selecting someone who is from multiple births (twins, triplets, etc)

Either someone is a twin/triplet/etc or they aren't. This two option nature is a strong implication we have a binomial probability.

The binomial probability formula is

B(x) = (n C x)*(p)^x*(1-p)^(n-x)

where x is the number of successes and the n C x refers to the nCr combination formula.

We want to know the value of B(3), ie the value of B(x) when we have exactly x = 3 children from multiple births.

------------------

B(x) = (n C x)*(p)^x*(1-p)^(n-x)

B(3) = (20 C 3)*(0.035)^3*(1-0.035)^(20-3)

B(3) = (1140)*(0.035)^3*(0.965)^(17)

B(3) = 0.026673

There's roughly a 2.6673% chance of the 20 person sample having exactly 3 children who are from multiple births.

Side note: You can compute 20C3 = 1140 using the conventional nCr formula, or you can use Pascal's Triangle as an alternative route.

A circular flower bed is 16m in diameter and has a circular sidewalk around it that is 3m wide. Find the area of the sidewalk in square meters. Use 3.14 for .PI

Answers

Answer:

Step-by-step explanation:

Given that the diameter of the flower bed is 17 m and the width of the side walk is 2 m for a total out side diameter of 21 m.

Total Area is pi *(D/2)^2 = 346.4 m^2

Now subtract the area of the 17 m diameter flower bed for the area of the sidewalk alone. 346.4 - (pi*(17/2)^2 = 346.4 - 227.0 = 119,4 m^2

Answer:  119,4 m^2

Step-by-step explanation:

The equation is area = p times r^2

A penquin dives at 18 feet per minute how many minutes does it take to
dive to -54 feet?

3 Minutes

30 Seconds

5 Minutes

4 Minutes

Answers

Answer:

5 minutes

Step-by-step explanation:

it dives at positive 18 feet in a minute

however in order to dive at -54 feet, it must dive -5 times

18-18-18-18-18= -54

and 1min =18feet

so it needs 5minutes for the 5times

OR

Let x=the time needed to dive at -54 feet's

so 1min=18

x= -54

-54=18x

dividing both sides by 18

-54/18=18x/18

x=-54/18

x=-5

however time cannot be negative

therefore x =5

this implies that the penguin dives at -54 feet in 5 minutes.

How many solutions exist for the given equation? 0.75(x 40) = 0.35(x 20) 0.35(x 20) zero one two infinitely many

Answers

Answer:

One solution

Step-by-step explanation:

0.75 (x + 40) = 0.35 (x + 20) + 0.35 (x + 20)

0.75x + 30 = 0.35x + 7 + 0.35x + 7

0.75x + 30 = 0.7x + 14

0.05x + 30 = 14

0.05x = -16

x = -320

Hope this helps!

Only one solution exists for the given equation.

What is meant by mathematical solution ?

A mathematical statement that demonstrates the equality of two mathematical expressions is a mathematical solution, which is the definition of an equation.

Here,

The mathematical equation given is,

0.75(x + 40) = 0.35(x + 20) + 0.35(x + 20)

By solving it,

0.75(x + 40) = 0.7(x + 20)

0.75x - 0.7x = 14 - 30

0.05x = -16

Therefore, the solution of x,

x = -16/0.05

x = 320

Hence,

Only one solution exists for the given equation.
