4 0

Answer:

Step-by-step explanation:

If you flip coins, you can get,

HT TH HH TT

There are 4 possible outcomes.

Out of these 4, Matt has to do chores if two heads are flipped. It is 1/4 chance.

Out of these 4, Mark has to do chores if two tails are flipped. Again, 1/4 chance.

The method of decision is far since both guys have the same chance of being picked to do chores.

To flip again, they would have to get either HT or TH out of the 4 choices. So 2/4=1/2 is the likeihood they must flip again.

Please help solve this equation. Show all steps please. No links or files.
maksim [4K]

Answer:

See below

Step-by-step explanation:

c = (a^2 + 3b) / 4       multiply both sides by 4

4c = a^2 + 3b           subtract a^2 from both sides

4c - a^2 = 3b            now divide both sides by 3

(4c-a^2) / 3 = b

One of the x-intercepts of the parabola represented by the equation y = 3x^2 + 6x − 10 is approximately (1.08, 0).
Igoryamba
3x^2 + 6x - 10 = 0

x  = [-6 +/- sqrt(^2 - 3*3*-10)] / 2*3

=  1.08 and -3.08

Other x -intercept is (-3.08,0)

What does AD equal? PICTURE INCLUDED* Triangle congruence and similarity.
mafiozo [28]

Answer:

AD = 7

Step-by-step explanation:

Given that the two triangles are similar by the SSS (side side side) postulate, the triangles share the same ratios when it comes to their sides.

We know the values for lines DB, EB and CB, therefore we can solve for AB, and subtract DB to find AD

We can solve the problem by solving for x:

\frac{x}{32} =\frac{21}{24}

Cross multiply.

24x = 672

Simplify.

x=28

Subtract the value of DB to find AD.

28-21=7

AD=7
