48/132
Step-by-step explanation:
The length of 1.5-inch screws is ...
36 × 1.5 in = 54 in
The length of 2-inch screws is ...
24 × 2 in = 48 in
The length of 2.5-inch screws is ...
12 × 2.5 = 30 in
The total length of all screws is ...
54 in + 48 in + 30 in = 132 in
Then the ratio of 2-in screw length to total screw length is ...
2-in : total = 48 : 132

The percent decrease of an idem that dropped in price from 50 to 43 is
Genrish500 [490]

Answer:

-14.000000000000002

Step-by-step explanation:

DETAILED ANSWER:

A change from 50 to 43 represents a negative change (decrease) of -14.000000000000002%

Use the formula found below on this webpage to find the percent change by replacing the given values:

Percent change = [(New - Old ) / |Old|] x 100%

Percent change = [(43 - 50) / |50|] x 100 = [(-7) / 50] x 100 = -14.000000000000002 % (decrease)

Where: 50 is the old value and 43 is the new value. In this case we have a negative change (decrease) of -14.000000000000002 percent because the new value is smaller than the old value.

wo urns contain white balls and yellow balls. The first urn contains 3 white balls and 6 yellow balls and the second urn contain
vlada-n [284]

Answer:

Answer is

\frac{7}{30}

Step-by-step explanation:

Given that there are two urns.  First urn contains 3 white balls and 6 yellow balls and the second urn contains 7 white balls and 3 yellow balls.

A ball is drawn from each urn.

Probability for ball from urn I is white = no of white balls/total balls in I urn

= \frac{3}{9} =\frac{1}{3}

Probability for ball from urn II is white = no of white balls/total balls in I urn

=\frac{7}{10}

Since drawing one ball from each urn is independent of the other we find

Prob that both balls are white=

Prob that ball from I urn is white *Prob that ball from II urn is white

== \frac{7}{10} *\frac{1}{3}\\=\frac{7}{30}
