Answer: 15

Step-by-step explanation: because there are 6 sides. 1/6*90=15

Hoped this helped!

When rolling a fair six-sided die 90 times, the expected number of times you would roll a 5 is about 15, calculated by multiplying the probability of rolling a 5 (1/6) by the number of rolls (90).

If you roll a fair six-sided die 90 times, you would expect each number to appear with equal probability because the die is fair. For each individual roll, the probability of getting a 5 is 1 in 6, as there are six possible outcomes. To find the expected number of times you would get a 5 in 90 rolls, you simply multiply the probability of rolling a 5 by the total number of rolls.

Expected number of fives = Probability of rolling a 5 × Total number of rolls
= (1/6) × 90

= 15

Therefore, you would expect to roll a 5 approximately 15 times out of 90 rolls.

Final answer:

The expression equivalent to (X^3)^4 is X^12. You calculate this by multiplying the exponents, resulting in X raised to the power of 3 times 4, which equals 12.

Explanation:

The expression (X^3)^4 is equivalent to X^(3*4), which is X^12. This follows the rule that when you raise a power to a power, you multiply the exponents. A number raised to the fourth power, like in this case, means that number is multiplied by itself four times. Generalizing this, for any base 'n' and exponents 'a' and 'b', the expression (n^a)^b is equal to n^(a*b).

For example, similar to (5^3)^4 being 5^(3*4) or 5^12, which is twelve fives multiplied together. Therefore, our given expression simplifies to X multiplied by itself a total of twelve times.

The probability of drawing 3 oranges from a basket of 6 oranges and 4 tangerines is 1/6 or approximately 0.167.

This problem is a probability question in the field of mathematics. It is asking us to find the probability that all three fruits drawn from the basket are oranges. This can be solved using the concept of combinations from probability theory.

The total number of fruits in the basket is 10 (6 oranges and 4 tangerines). We want to draw a sample of 3 fruits. The number of ways to draw 3 fruits from a total of 10 (regardless of type) is given by the combination formula C(n, r), where n is the total number of items and r is the number of items to choose. So we have C(10, 3) = 120 possible ways.

Next, consider the scenario we're interested in--drawing 3 oranges. The total number of ways to draw 3 oranges from a total of 6 oranges is C(6, 3) = 20 possible ways.

So, the probability of drawing 3 oranges is the number of ways to draw 3 oranges divided by the total number of ways to draw 3 fruits. So, the probability is 20/120 = 1/6 or approximately 0.167.

Final answer:

The probability of drawing 3 oranges from a basket containing 6 oranges and 4 tangerines is found using combinations. The calculation shows that the probability of selecting all oranges in a draw of 3 fruits is 1/6.

Explanation:

The question asks to find the probability that when three fruits are drawn from a basket containing 6 oranges and 4 tangerines, all three are oranges. This is a problem of probability without replacement, which can be solved using combinations.

To find the probability of drawing 3 oranges out of 3 fruits, we calculate the combinations of choosing 3 oranges from 6 and then divide it by the combinations of choosing 3 fruits from the total 10 fruits in the basket.

The number of ways to select 3 oranges out of 6 is given by the combination formula C(n, k) = n! / (k!(n - k)!), where n is the total number of items, and k is the number of items to choose. So, we have:

Ways to pick 3 oranges: C(6, 3)

Total ways to pick 3 fruits: C(10, 3)

Then the probability is calculated by:

P(all oranges) = C(6, 3) / C(10, 3)

Calculating the combinations, we have:

Thus, the probability that all three fruits are oranges is 1/6.

Answer:

120 square units

Step-by-step explanation:

In triangle PSQ, PS=SQ. Let PS=SQ=x units.

Since SQ-PQ=1, PQ=SQ-1=x-1 units.

The perimeter of the triangle PSQ is 50 units, so

PS+SQ+PQ=50 units.

Substitute PS=SQ=x un. and PQ=x-1 un.

x+x+x-1=50

3x=51

x=17

Hence

PS=SQ=17 units,

PQ=16 units.

Exterior angle theorem - the sum of two interior angles (which in this case would be angle R and N) is equal to the measure of the exterior angle.

Answer:

Step-by-step explanation:

Use the given information to determine what the angles can be.

  g = 2x -90 . . . . given

  g > 0 . . . . . . . . . given

  2x -90 > 0

  2x > 90 . . . . . add 90

  x > 45 . . . . . . divide by 2

__

  h = 180 -2x

  h > 0

  180 -2x > 0

  180 > 2x

  90 > x

__

The requirement that both angles be greater than zero puts limits on x:

  45 < x < 90

We can put this back into the given relations for g and h:

  g = 2x -90

  x = (g +90)/2

  45 < (g +90)/2 < 90 . . . . substitute for x

  0 < g/2 < 45 . . . . . . . . . . subtract 45

  0 < g < 90 . . . . . . . . . . . . g is an acute angle

Similarly, ...

  h = 180 -2x

  x = (180 -h)/2 = 90 -h/2

  45 < (90 -h/2) < 90 . . . . substitute for x

  -45 < -h/2 < 0 . . . . . . . . . subtract 90

  90 > h > 0 . . . . . . . . . . . multiply by -2; h is an acute angle

__

We can add the angle measures to see if they are supplementary or complementary:

  g + h = (2x -90) +(180 -2x)

  g + h = 90 . . . . . simplify; the angles are complementary

To find the value of f(x) when x=2 for the function f(x) = 42x - 100, substitute 2 for x, giving f(2) = 84 - 100, which simplifies to f(2) = -16.

Explanation:

The student is asking to evaluate the function f(x) = 42x - 100 when x = 2. To do this, we simply substitute 2 for x in the equation, which gives us f(2) = 42(2) - 100. Performing the multiplication first, we get 84 - 100. Thus, f(2) equals -16.

Answer:

420 miles

Step-by-step explanation:

Distance = rate × time

Let's say that the distance is D and that John's speed is S.  We know that:

D = S × 6

When Elliot drives at speed S+14:

D = (S+14) × 5

Setting D = D:

S × 6 = (S+14) × 5

6S = 5S + 70

S = 70

Therefore, the distance D is:

D = 70 × 6

D = 420

The distance from John's house to Miami is 420 miles.

The distance from John's house to Miami, Florida is 420 miles, calculated by first determining John's speed using the given information and then applying the formula distance = speed times time.

To calculate the distance from John's house to Miami, Florida, we need to use the formula distance = speed times time. John's travel time is 6 hours. We are not directly given John's speed; instead, we know that Elliot drives 14 mph faster than John and it takes him 5 hours to cover the same distance. Let's denote John's speed as 's'. Therefore, Elliot's speed is 's + 14 mph'. Setting up an equation based on Elliot's travel information, we have distance = (s + 14 mph) times 5 hours.

Since they both travel the same distance, we can also write John's travel information as distance = s times 6 hours. Equating both expressions for distance, we get: s times 6 = (s + 14) times 5. Simplifying, we have 6s = 5s + 70, which leads to s = 70 mph. This means John's speed is 70 mph.

To find the distance to Miami, we return to the distance formula and substitute John's speed: distance = 70 mph times 6 hours = 420 miles. Hence, the distance from John's house to Miami, Florida is 420 miles.

x = - 9, x = - 3

Step-by-step explanation:

Given

x² + 12x + 27 = 0

To factorise the quadratic

Consider the factors of the constant term (+ 27) which sum to give the coefficient of the x- term (+ 12)

The factors are + 9 and + 3, since

9 × 3 = 27 and 9 + 3 = 12, hence

(x + 9)(x + 3) = 0

Equate each factor to zero and solve for x

x + 9 = 0 ⇒ x = - 9

Assuming the coin is fair;

The probability of getting heads in a single toss is, P(H) = 1/2

The probability of getting tails in a single toss is, P(T) = 1/2

Now, P(H,H,H) is the probability of obtaining 3 heads in the e tosses. Since each toss is independent of the others,;

P(H,H,H) = P(H)*P(H)*P(H)

              = 1/2 * 1/2 * 1/2 = 1/8

On the other hand, P(H,T,H) is the probability of obtaining a head followed by a tail followed by a final head. Using the independence property;

P(H,T,H) = P(H)*P(T)*P(H)

              = 1/2 * 1/2 * 1/2 = 1/8

Therefore, P(H,H,H) = P(H,T,H)

10.

We are informed that a coin is tossed and a number cube is rolled. We are to determine the following probability;

P(heads, a number less than 5)

Assuming the coin is fair;

The probability of getting heads in a single toss is, P(H) = 1/2

Assuming the number cube is fair as well, the probability of rolling a number less than 5 is;

4/6 = 2/3

This is because there are 4 numbers less than 5, (1, 2, 3, 4) while the cube has 6 sides.

P(heads, a number less than 5), the events presented here are independent since the outcome from tossing the coin does not in any way determine the outcome from rolling the number cube. Therefore,;

P(heads, a number less than 5) = P(heads)*P(a number less than 5)

                                                    = 1/2 * 2/3 = 1/3
