Answer:

P(vanilla cupcake)= 1/2

Step-by-step explanation:

Knowing that:

3 vanilla cupcakes

3 other cupcakes

Total = 6

To Find:

What is the experimental probability that the next cupcake sold will be a vanilla cupcake?

Write your answer as a fraction or whole number.

P(vanilla cupcake)=

Solve:

Experimental probability is expressed as:

(Favorable outcomes) / (Total outcomes)

The favorable outcome in this situation is vanilla cupcakes. There were 3 vanilla cupcake sold, so this is the numerator of our fraction.

To find the total outcomes we add 3 + 3, which equals 6. This will be the denominator of our fraction.

The fraction used to express experimental probability will be: 3/6

We can further simplify this to 1/2.

Thus:

P(vanilla cupcake)= 1/2 or 3/6

1/40 is the probability that this is the correct code.

It is a branch of mathematics that deals with the occurrence of a random event.

Given that Liam is trying to remember a 3-digit code.

the first digit is a cube number so the first digit may be 1 or 8.

the second digit is a factor of 16.

The factor of 16 are 1, 2, 4 , 8.

Third digit is an odd number so the third digit may be 1, 3, 5, 7, 9.

There are 2×4×5 possibilities of Liam code.

40 possibilities

the probability that this is the correct code is 1/40

Hence, 1/40 is the probability that this is the correct code.

Answer:

10.14π

Step-by-step explanation:

First we have to work backwards. We know the forumla for circumference is pi x diameter. So we have to work backwards. 20 divided by pi is 6.37. So thats our diameter. Now that we that we can put it into our forumla for area. A= π x R^2.

The raidus is half of the diamater so 6.37/2. Which equals 3.185. Now we that into our formula. A= π x 3.185^2. Now we keep simplyifying the equation. 3.185^2=10.14. So now we have A=10.14π

Step-by-step explanation:

you have to be careful with the precise notation of terms and expressions.

you keep using only -7 for everything.

i suspect you mean 7 and -7, right ?

if that is correct, then just remember this :

on a number line the positive values are on the right, and the negative values on the left.

in fact, the further right you go, the larger the number gets. and the further left you go, the smaller (or lower) the number gets.

e.g. -7 is smaller than -6.

and so, -7 would be to the left of 7, because -7 < 7.

or vice versa :

7 would be to the right of -7, because 7 > -7

Answer:

4/41

Step-by-step explanation:

Answer:

Use simultaneous equation for this problem

y= number of adults

x = number of children

3y + 2x = 160

y + x = 60

then we double the second equation

3y + 2x = 160

2y + 2x = 120

we cancel x by elimination

3y - 2y = 160 - 120

y = 40

The inequality x -4 > 2 uses a greater than symbol

All numbers lesser or equal to 6 are not a solution of the inequality x -4 > 2

The inequality is given as:

x -4 > 2

Add 4 to both sides of the inequality

x - 4 + 4 > 2 + 4

Evaluate the sum

x > 6

The above means that only numbers greater than 6 are in the solution of the inequality.

Since the options are not given, I will give a general solution that all numbers lesser or equal to 6 are not a solution of the inequality x -4 > 2

Her mistake is that she should plot the point (0, 5) first, not (1, -3)

Step-by-step explanation:

First I simplified the equation given.

y - 3 = 2 (x + 1)

y - 3 = 2x + 2

  +3         +3

y = 2x + 5

Since 5 is our y-intercept we would want to graph that first, which would be (0, 5) as a point.
