He two-way table shows the medal count for the top-performing countries in the 2012 summer olympics.

a 5-column table has 5 rows. the first column has entries united notes, china, russia, great britain, total. the second column is labeled gold with entries 46, 38, 24, 29, 137. the third column is labeled silver with entries 29, 27, 26, 17, 99. the fourth column is labeled bronze with entries 29, 23, 32, 19, 103. the fifth column is labeled total with entries 104, 88, 82, 65, 339.

which statement is true?

the probability that a randomly selected silver medal was awarded to great britain is startfraction 17 over 99 endfraction.
the probability that a randomly selected medal won by russia was a bronze medal is startfraction 32 over 103 endfraction.
the probability that a randomly selected gold medal was awarded to china is startfraction 88 over 137 endfraction.
the probability that a randomly selected medal won by the united states was a silver medal is startfraction 104 over 339 endfraction.

think about it deeply and passionately about this property

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
