1*5=5 and 3*5=15. 2*3=6 and 5*3=15. We made the denominator the same. We need to add 5 and 6 and we get 11. Correct answer is 11/15

Find the probability that the hitter makes 10 outs in 10 consecutive at-bats, assuming at-bats are independent events. Hint:

emmainna [20.7K]

Answer:

0.037

Step-by-step explanation:

If the hitter makes an out 72% of the time, then the probabilty that he makes hit in 1 at-bat is $p=0.72$ and the probabilty that he doesn't make hit in 1 at-bat is $q=1-p=1-0.72=0.28.$

The probability that the hitter makes 10 outs in 10 consecutive at-bats, assuming at-bats are independent events is

$P=p^{10}=(0.72)^{10}\approx 0.037.$

Please explain how to find the simplest form of 7/28! I did it in 5th grade but forgot! Explain please.

Lapatulllka [165]

$\sf \frac{7}{28} = \frac{7 \times 1}{7\times 4}\\ We~can~divide~by~7~on~both~the~numerator~and~denominator\\\frac{7\times 1\div 7}{7\times 4\div 7} = \frac{1}{4}$

So in simplest form it would be 1/4

$x=0.\overline{3}\\
10x=3.\overline{3}\\
10x-x=3.\overline{3}-0.\overline{3}\\
9x=3\\
x=\dfrac{3}{9}=\dfrac{1}{3}\\\\
x=-0.\overline{2}\\
10x=-2.\overline{2}\\
10x-x=-2.\overline{2}-(-0.\overline{2})\\
9x=-2.\overline{2}+0.\overline{2}\\
9x=-2\\
x=-\dfrac{2}{9}\\\\
x=1.\overline{7}\\
10x=17.\overline{7}\\
10x-x=17.\overline{7}-1.\overline{7}\\
9x=16\\
x=\dfrac{16}{9}=1\dfrac{7}{9}$

$x=-2.\overline{6}\\
10x=-26.\overline{6}\\
10x-x=-26.\overline{6}-(-2.\overline{6})\\
9x=-26.\overline{6}+2.\overline{6}\\
9x=-24\\
x=-\dfrac{24}{9}=-2\dfrac{2}{3}\\\\
x=0.4\overline{6}\\
10x=4.\overline{6}\\
100x=46.\overline{6}\\
100x-10x=46.\overline{6}-4.\overline{6}\\
90x=42\\
x=\dfrac{42}{90}=\dfrac{7}{15}$

$x=-1.8\overline{3}\\
10x=-18.\overline{3}\\
100x=-183.\overline{3}\\
100x-10x=-183.\overline{3}-(-18.\overline{3})\\
90x=-183.\overline{3}+18.\overline{3}\\
90x=-165\\
x=-\dfrac{165}{90}=-1\dfrac{5}{6}$
