Anna [14]

Answer:

There is a 0.78% probability that Eli chooses 7 winners in a row.

Step-by-step explanation:

There were 7 Super Bowls.

In each Super Bowl, there were two teams.

So, the probability that Eli chooses 7 winners in a row is

$P = \frac{1}{2}*\frac{1}{2}*\frac{1}{2}*\frac{1}{2}*\frac{1}{2}*\frac{1}{2}*\frac{1}{2} = \frac{1}{128} = 0.0078$

There is a 0.78% probability that Eli chooses 7 winners in a row.

A flag is the shape of an isosceles triangle, with two equal sides and a base. Sara has enough fabric to make a flag with a peri

s344n2d4d5 [400]

Lets assume the sides of the isosceles triangle are:

Side A: x

Side B: x

Base: x/2

x+x+x/2= 46.8cm

2x+x/2=46.8cm

4x+x=93.6

5x=93.6

x= 18.72

Side A: 18.72cm

Side B: 18.72cm

Base: 9.36cm

The base of the largest triangular flag Sara can make is 9.36cm.

2x+x/2= 46.8cm

You multiply two integers. You increase one of them by 1 and decrease the other

snow_tiger [21]

Integers are numbers without decimals

The integers could you have multiplied are 9 and 2

Let the numbers be x and y

So, we have:

$\mathbf{x \times y}$

Increase x by 1 and reduce y by 1.

So, we have

$\mathbf{(x +1) \times (y -1) = 6 + xy }$

Open brackets

$\mathbf{xy -x + y - 1 = 6 + xy}$

Subtract xy from both sides

$\mathbf{ -x + y - 1 = 6}$

Collect like terms

$\mathbf{ -x + y = 6 + 1}$

$\mathbf{ -x + y = 7}$

Rewrite as:

$\mathbf{ y -x= 7}$

The above means that, the difference between the integers is 7.

There are several integers that fit the above <em>description</em>;

One possibility is: 9 and 2
