I answered a similar problem yesterday.
In three coin tosses there are 8 possible outcomes:
H H H
H H T
H T H
T H H
T T H
T H T
H T T
T T T

Of those results, four out of the eight have at least 2 tails and so the probability is (4/8) or50%

If you need the probability of getting EXACTLY 2 tails then the probability is (3/8) or .375

A shape is shown on the centimetre grid below.
krok68 [10]

Answer:

The area of the shape after it has been enlarged by

scale factor 2 will be: 10 cm²

Step-by-step explanation:

The Area is basically a measure of how much space in square units there is inside an object.

As the shape is shown on the centimeter grid.

  • The shape clearly occupies the space of 5-centimeter squares.

We also know that If the scale factor > 1, the image is enlarged.

As we know to determine the area of the shape after it has been enlarged by scale factor 2, all we need to do is to multiply the area of the original shape by 2.

The area of original shape = 5 cm²

The area of the shape after the dilation by a scale factor 2 = 5 × 2 = 10 cm²

Thus, the area of the shape after it has been enlarged by

scale factor 2 will be: 10 cm²

How do i isolate y in 4x - 2y = 22
Irina18 [472]

4x - 2y = 22

Start by adding 2y to both sides to cancel out the -2y

4x = 22 + 2y

Now you can divide by 4

x = 22/4 + 2y/4

Reduce all the fractions to get your answer, which is

x = \frac{11}{2} + \frac{y}{2}
