Answer: its not right triangle

Step-by-step explanation: no becauce  [tex]11^2+15^2\neq 18^2=> 346\neq 324[/tex]

Answer: 2*3^2 = 18   3*5^2 = 75      75 + 18 = 93

The probability that Belle will select two hearts is 2/15.

To find the probability of Belle selecting two hearts, we need to calculate the probability of selecting a heart on the first draw and then, given that the first card was a heart, the probability of selecting another heart on the second draw.

Total number of cards = 3 (star cards) + 4 (hearts cards) + 3 (spade cards) = 10 cards

Probability of selecting a heart on the first draw = 4 (hearts cards) / 10 (total cards) = 2/5

After selecting a heart on the first draw, there will be 9 cards remaining, with 3 hearts cards left.

Probability of selecting a heart on the second draw, given that the first card was a heart = 3 (hearts cards) / 9 (remaining cards) = 1/3

To find the probability of both events happening (selecting two hearts), we multiply the probabilities:

Probability of selecting two hearts = (2/5) x (1/3) = 2/15

Therefore, the probability that Belle will select two hearts is 2/15.

Answer:

m = - 2/3 or

m = - 0.66667.

I don't know which form is simpler.

Step-by-step explanation:

All you want is the slope.

The slope formula is

m = (y2 - y1) / (x2 - x1)

y2 =  7

y1 = 3

x2 = - 2

x1 = 4

My choice of which one is 1 and which one is 2 is totally arbitrary. You could have made y2 = 3 and y1 = 7 and x2 = 4 and x1 = -2

m = (7 - 3) / (-2 - 4)

m = 4 / - 6

m = -2/3 or

m = - 0.6667

Answer: there are total 100,000 5-digit PINs.

Three Possible outcomes          Associated X values

            12345                                        5

            00001                                          1

Step-by-step explanation:

Here,  X = the number of nonzero digits in a randomly selected 5-digit PIN that has no restriction on the digits.

Possible number of outcomes = 10 x 10 x 10 x 10 x 10

= 100,000

Possible outcomes          Associated X values

12345                                        5

Answer:

12 rabbits

Step-by-step explanation:

Take long word problems like these step-by-step:

The pet store has 96 pets. Since half are fish, there are 48 fish. If one eighth of the pets are hamsters, there are 12 hamsters

If an eighth of the pets are dogs then there are 12 dogs and if an eighth of the pets are cats then there are also 12 cats. Since the rest are rabbits, we can subtract the amount of non-rabbits from the total (96 pets). There are 48+12+12+12=84 non-rabbits, and therefore 96-84=12 rabbits.

Answer:

Step-by-step explanation:

115+94+107+2x=360 degree(sum of interior angles of four angles is always 360 degree)

316+2x=360

2x=360-316

x=44/2

x=22 degree

Problem 5

------------------

Explanation:

We have these four identities

Notice how computing i^4 leads us back to 1. So i^4 = i^0. The pattern repeats every 4 terms. So we divide the exponent by 4 and look at the remainder. We ignore the quotient entirely. We can see that 28/4 = 7 remainder 0. Meaning that i^28 = i^0 = 1.

We can think of it like this if you wanted

i^28 = (i^4)^7 = 1^7 = 1

Then the sqrt(-36) becomes 6i

So overall, we end up with the final answer of 6i

=============================================

Problem 6

------------------

Explanation:

We'll use the ideas mentioned in problem 5

46/4 = 11 remainder 2

i^46 = i^2 = -1

sqrt(-9) = 3i

The two outside negative signs cancel out, but there's still a negative from -1 we found earlier. So we end up with -3i

In other words, here is one way you could write out the steps

[tex]-i^{46}*-\sqrt{-9}\\\\-i^{2}*-3i\\\\i^{2}*3i\\\\-1*3i\\\\-3i\\\\[/tex]

=============================================

Problem 7

------------------

Work Shown:

i^10 = i^2 because 10/4 = 2 remainder 2

i^19 = i^3 because 19/4 = 4 remainder 3

i^7 = i^3 because 7/4 = 1 remainder 3

Again, all we care about are the remainders.

[tex]i^{10}+i^{19} - i^{7}\\\\i^{2}+i^{3} - i^{3}\\\\i^{2}\\\\-1[/tex]

=============================================

Problem 8

------------------

Work Shown:

i^22*i^6 = i^(22+6) = i^28

Earlier in problem 5, we found that i^28 = i^0 = 1

So,

[tex]i^1 - \left(i^{22}*i^{6}\right)\\\\i^1 - i^{28}\\\\i^1 - i^{0}\\\\i - 1\\\\-1+i[/tex]

Answer:

Step-by-step explanation:

The margin of error for the sample is roughly 0.255 gm.

A set of values' variance or dispersion is measured by the standard deviation.

A confidence interval is made up of the mean of your estimate plus and minus the estimate's range.

This is the range of values you expect your estimate to fall within if you repeat the test, within a given level of confidence. Confidence is another name for probability in statistics.

Given,

Standard deviation = 3.4 gm

Population mean = 23.5 gm

Number of pigs = 35

We know, Margin of Error = [tex]\frac{\sqrt{\mu\times\sqrt{\sigma}}}{n}[/tex]

ME =  [tex]\frac{\sqrt{23.5\times\sqrt{3.4}}}{35}[/tex].

ME = 0.225 gm.

As a result, the sample mean's margin of error is roughly 0.255 gm.

Step-by-step explanation:

When you multiply two quantities under a root, it is just like normal multiplication. 2*18 is 36, which is the perfect square of six. Since this number can be expressed as p/q (where p and q are integers; the values here are 6 and 1), it is rational.
