I HAVE A FEW MINS PLEASE HEELPPP! FOR BRIANLIEST!

riadik2000 [5.3K]

Answer:

For each of the possible outcomes add the numbers on the two dice and count how many times this sum is 7. If you do so you will find that the sum is 7 for 6 of the possible outcomes. Thus the sum is a 7 in 6 of the 36 outcomes and hence the probability of rolling a 7 is 6/36 = 1/6

In 1975 1000 tons of coal was manufactured. It is 10% greater in 1976 and 5% less in 77. What is the final about of coal in 1977

Digiron [165]

In 1975 it was 1000tons, ok, well, in 1976 it went up by 10%, how much is a 10% increase?

$\bf \begin{array}{ccllll}
coal&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
1000&100\\
x&100+10
\end{array}\implies \cfrac{1000}{x}=\cfrac{100}{100+10}\implies \cfrac{1000\cdot 110}{100}=x
\\\\\\
1100=x$

well, in 1976 it was 1100 tons then, and in 1977 it went down by 5% of 1100, well, if we take 1100 to be the 100%, then what is a 5% decrease?

$\bf \begin{array}{ccllll}
coal&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
1100&100\\
x&100-5
\end{array}\implies \cfrac{1100}{x}=\cfrac{100}{100-5}\implies \cfrac{1100\cdot 95}{100}=x$
