The base of a triangle is....

Answer:

a=49

Step-by-step explanation:

You would solve this the same way you would with any other triangle problem. You will plug in for the base and the height in this formula a=\frac{1}{2}bh.

a=\frac{1}{2}bh\\a=\frac{1}{2}(\sqrt{343})(\sqrt{28})

Now we will multiply the two radicands.

a=\frac{1}{2}\sqrt{9604}

For this we will split the 9604 into 49 and 196.

a=\frac{1}{2}\sqrt{49}\sqrt{196}

Now we just take the square roots of those two and since they're perfect squares they'll be whole numbers.

a=\frac{1}{2}(7)(14)

Next we just multiply everything together.

a=49

liq [111]

The probability of getting exactly zero tails is 1/8.

Step-by-step explanation:

When a fair coin is tossed three time, the set of equally likely outcomes is:

S= {HHH,HHT, HTH, THH, HTT, THT, TTH, TTT}

n(S)=8

Let A be the event that there are exactly zero tails which means there are all heads

Then

A= {HHH}

n(A)=1

P(A)=\frac{n(A)}{n(S)}\\=\frac{1}{8}

The probability of getting exactly zero tails is 1/8.

What is the slope of this line?
nataly862011 [7]

Answer: -\frac{8}{5}

Remember: RISE/RUN (y/x). Lines that are increasing have a positive slope, and lines that are decreasing have a negative slope.

You can find the slope in two ways:

1. Useful if the line is graphed: count the units between 2 points on the line.

  • Let's use the points (-1, 4) and (4, -4).
  • (-1, 4) is 8 units higher than (4, -4) and 5 units to the left of (4, -4).
  • Because the line is decreasing, the slope is negative.
  • Therefore, the slope is -\frac{8}{5}.

2. Useful if the line is not graphed: find the difference between the y-coordinate values divided by the difference of the x-coordinate values.

  • Let's use the points (-1, 4) and (4, -4).
  • \frac{-4 - 4}{4 - (-1)} = \frac{-8}{5}
  • Therefore, the slope is -\frac{8}{5}.
