If two coins are tossed together, then the chance for falling with heads up is 1/2. The chance for tails is also 1/2. Therefore,

the chance that both coins will land on heads is _1/4___. The chance for the first coin to fall on tails and the second on heads is also ___1/4____. However, one head and one tail can be obtained if the first coin to fall on heads and the second on tails. There, the total probability of obtaining a head on one coin and a tail on the other is ___1/2___. The chance for both coins to land on tails is __1/4____. In summary, two coins tossed together are expected to land on heads _1/4_ of the time; one head and one tail __1/2___ of the time; two tails __1/4___ of the time. Stated as a ratio instead of fractions, the expected result is _____4:4 or just_____.

Answer:

Stated as a ratio instead of fractions, the expected result is _____4:4 or just_____.

1

Step-by-step explanation:

In this particular case, the result of the two coins tossed together landing on heads 1/4 of the time; one head and one tail 1/2 of the time; and two tails 1/4 of the time is equal to 1.

This is because 1/4 + 1/2 + 1/4 = 1.  It is the sum of all probabilities in the set or distribution.  This sum is always equal to 1.  Therefore, the sum of a probability distribution is the collection of the probabilities that define the chance of the various outcomes of an event or experiment.

What is the sun of 185 and h
Ksenya-84 [330]

Answer:

185 + h

Step-by-step explanation:

Question: What is the sum of 185 and h?

Sum means the answer to an addition problem, so we need to add.

185 +  h

This expression can not be simplified any further, so 185 + h is your answer.

Hope this helps :)

A teacher has been given £35 to spend on pencils and rulers.
SSSSS [86.1K]
Packet of 12 pencils = p
Packet of 30 rulers = r

p = £2.15
r = £6.00

£35 = 4r + xp
£35 = 4(£6.00) + x(£2.15)
£35 = £24 + £2.15x
£11 = £2.15x
x = 5.12

Since she can buy 5.12 packets of pencils, it is equal to 5 packets of pencils.

Consider the graph of function g below. A diagonal curve declines from (negative 1, 9) through (0, 6), (2, 0), (3, negative 3),
KatRina [158]

The parent function, f(x) = x, might undergo the following series of transformations to produce the graph: Reflect over the y-axis, vertical stretch by a factor of 2, and then shift up 6 units.

<h3>What is geometric transformation?</h3>

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

The converted function, when compared to the original function, will be obtained as y = -2x + 6 if we plot it on the coordinate plane.

The only method by which the provided graph may be converted to the coordinates specified in the problem is;

Reflect over the y-axis, multiply the vertical stretch by two, and then move up six units.

Thus, the parent function, f(x) = x, might undergo the following series of transformations to produce the graph: Reflect over the y-axis, vertical stretch by a factor of 2, and then shift up 6 units.

The table below shows field goal statistics for three different kickers. Order the kickers by their field goal success rate from
nikklg [1K]

Answer:

Kicker C, kicker B, and then kicker A

Step-by-step explanation:

Just divide the field goals made by field goals attempted to get the success rate. A = 12 / 14 = 0.857      B = 15 / 18 = 0.83      C = 19 / 24 = 0.79

0.79 < 0.83 < 0.857
