The event space of getting exactly one tail is {HT, TH}
The sample space is {HH, HT, TH, TT}

There are two ways to get exactly one tail, out of 4 total possible outcomes. 
So 2/4 = 1/2 is the answer

David has 3 1/2 cups of blueberries. He uses 1/4 of a cup of blueberries to make a breakfast smoothie. He uses 1/2 of the remain
dusya [7]

Answer:

1\frac{5}{8} cup of blueberries

Step-by-step explanation:

Since David starts out with 3 1/2 cups of blueberries and uses 1/4 cup to make a smoothie, we will need to subtract 1/4 from his starting amount of 3 1/2

  • 3\frac{1}{2}-\frac{1}{4}  =3\frac{1}{4} David now has 3 1/4 cup of blueberries

David then uses half of this new amount of blueberries to make his pancakes. We will need to divide by 2 in order to figure out how much half is

  • First we can turn 3 1/4 into an improper fraction to make it easier to work with → 3 1/4 = 13/4
  • Now dividing 13/4 by 2 gives us \frac{\frac{13}{4} }{2} =(\frac{13}{4})(\frac{1}{2}) = \frac{13}{8}
  • David used 13/8 cups of blueberries to make his pancakes
  • Turning this back into a mixed number leaves him with 1 5/8 cup of blueberries

Fofino [41]

Answer:

I'm not sure what that U is for.

The answer is 459,461     These two do add to 920

Step-by-step explanation:

Remark

I'm going to make sure you are using consecutive odd numbers.

Let the smaller number = 2x - 1

Let the larger number = 2x + 1

Equation

2x - 1 + 2x + 1 = 920

4x = 920

x = 230

The consecutive numbers are 2*230 - 1 = 459

and 2*230 + 1                                             = 461

How do i graph x+4y=8​
Andrew [12]

Answer:

x = 8  y = 2

(8,2)

Step-by-step explanation:

You have to find the value of both x and y

x + 4y = 8

to find x you have to cancel out y so,

x + 4(0) = 8

x = 8

to find y you have to cancel out x

0 + 4y = 8

4y = 8

divide both sides by 4

y = 2

Hope this Helps!!!

Alan buys 5.3 ounces of sour patch kids candy. After sharing with his friends he returns to buy an additional 6.75 ounces. How m
Natasha_Volkova [10]

Answer:

Alan buys 12.05 ounces of sour patch kids candy in all.

Step-by-step explanation:

We are given that Alan buys 5.3 ounces of sour patch kids candy. After sharing with his friends he returns to buy an additional 6.75 ounces.

And we have to find the total ounces he buys in all.

As we know that for finding the total quantity or amount, we will use addition for calculating it.

Firstly, Alan buys = 5.3 ounces of sour patch kids candy

Additional ounces of sour patch kids candy Alan buys = 6.75

So, the total ounces of sour patch kids candy he buys in all = 5.3 + 6.75

                                                                                                   = 12.05 ounces

Hence, he buys 12.05 ounces in all.
