Zepler [3.9K]

Answer:

<u></u> $\frac{10m^{10}n^{6}p^{9}}{y}$

Step-by-step explanation:

Simplifying the numerator :

⇒ (-5m⁷n⁰p⁵)(2m⁴n³p²)³

⇒ (-5m⁷p⁵)(8m¹²n⁹p⁶)

⇒ (-5)(8)(m)⁷⁺¹²n⁹(p)⁵⁺⁶

⇒ <u>-40m¹⁹n⁹p¹¹</u>

<u />

Dividing by the denominator :

⇒ $\frac{-40m^{19}n^{9} p^{11} }{-4m^{9}n^{3}p^{2}y} }$

⇒ $\frac{10m^{10}n^{6}p^{9}}{y}$

charlie has 2 fair coins. he repeatedly tosses the pair of coins simultaneously (i.e., two tosses at a time), until he has seen

Serggg [28]

By using the trial method we get a total number of trials taken by Charlie to see both sides of both the coins is 4.

<h3>What is probability?</h3>

Probability is the name of the area of mathematics that deals with the examination of random events. The ratio of favorable occurrences to the total number of events is used to calculate an event's probability.

P(E) = F(E)/T (E)P(E)

It stands for the probability that an event will occur.

F(E) = Amount of favorable occurrences

Total number of trials (T(E))

Given that Charlie has 2 fair coins.

If he tosses the pair of coins simultaneously, then the number of samples can be HH, HT, TH, TT.

So to see both sides of both the coins he should toss the coin four times.

Katie invests $5,000 in an account earning 4% interest, compounded annually for 5 years. Two years after Katie's initial investm

Lyrx [107]

Emily earned $166 more in her account than Katie.

We use the compound interest formula for both of these:

$A=p(1+r)^t$

For Katie's deposit:
$A=5000(1+0.04)^5=5000(1.04)^5 = 6083.26$

This gives Katie 6083.26-5000 = 1083.26 in interest (1083, to the nearest dollar).

For Emily's deposit:
$A=10000(1+0.04)^3=10000(1.04)^3=11248.64$

This means she earned 11248.64-10000=1248.64 in interest (1249, to the nearest dollar).

The difference in interest is given by 1249-1083=166

Ona ran 6.25 miles. How many yards did she run.

Anastaziya [24]

1 mile = 5280 feet, so we multiply 6.25 by 5280 to get 33000 feet. 1 yard = 3 feet, so we divide 3 by 33000 to get 11000 yards.
