Answer:

Step-by-step explanation:

The probability of being dealt a fourth diamond after 3 of the 4 cards dealt are diamonds is 10/ 49.

Out of the four cards that you have been dealt, 3 of them are diamonds, so there is only one card left.

The deck of cards has 13 diamonds and 39 non-diamonds cards, so the probability of drawing a diamond from the remaining deck after taking 3 cards is

= (13 - 3)/ (52 - 3)

= 10/ 49

Since you want a fourth diamond, the probability of being dealt a fourth diamond is 10/49.

It's important to notice that this problem is a conditional probability problem, where the probability of an event happening is dependent on the outcome of another event. In this case, the event of getting a fourth diamond depends on the fact that you already have 3 diamonds in your hand.

Step-by-step explanation:

For a polynomial of the form ax^2 + bx + c, rewrite the middle term as a sum of two terms whose product is a • c = 6 • − 1 = − 6 and whose sum is b = − 1.

1) Reorder terms. = 6a^2 − b^2 − ab

2) Reorder −b^2 and − ab. = 6a^2 − ab − b^2

3) Factor −1 out of −ab. = 6a^2 − ( ab ) − b^2

4) Rewrite −1 as 2 plus −3. = 6a^2 + ( 2 − 3 ) ( ab ) − b^2

5) Apply the distributive property. = 6a^2 + 2 ( ab ) − 3 ( ab ) − b^2

6) Remove unnecessary parentheses. = 6a^2 + 2ab − 3 ( ab ) − b^2

7) Remove unnecessary parentheses. = 6a^2 + 2ab − 3ab − b^2

Factor out the greatest common factor from each group.
1) Group the first two terms and the last two terms.
= ( 6a^2 + 2ab ) − 3ab − b^2

The inequalities to represent all of the constraints in Eric's problems using x for the number of adults and y for the number of children are as follows:

An inequality is a statement that compares two expressions using one of the following symbols: <, >, <=, >=, or ≠. The expressions being compared can be numbers, variables, or a combination of both.

The result of an inequality is either true or false. For example, the inequality 2x + 3y < 6 represents a set of ordered pairs (x,y) that satisfy the inequality. It describes all the points on a coordinate plane that fall under the solution set of the inequality.

From the inequalities above,

Answer:

  neither

Step-by-step explanation:

You want to know if the graphed function is even or odd. It appears to be a cubic with a y-intercept of about 40.

Even functions are symmetrical about the y-axis. A function is even if ...

  f(x) = f(-x)

Even polynomial functions have terms that are all even powers of the variable.

Odd functions are symmetrical about the origin. A function is odd if ...

  f(x) = -f(-x)

Odd polynomial functions have terms that are all odd powers of the variable.

The graphed polynomial function has a non-zero added constant (the y-intercept value), so has both even and odd terms. It is neither even nor odd.

The graph is neither symmetrical about the y-axis, nor symmetrical about the origin.

Answer: 4.2

Step-by-step explanation: First, you'd need to re-arrange the decimals so, you can get 4.65.........

Then, you round up to get about 4.7

Another way is to round up the decimals, so your new equation:

[tex]\frac{21}{5}[/tex]

Then, you'd divide to get 4.2. This way is more of an estimate than the 1st way; the 1st way is an exact answer [rounded] I hope this helped.

Answer:

  4.64

Step-by-step explanation:

You want an estimate of the quotient 21.4/4.6.

Multiplication and division by 5 are simplified by the relation ...

  5 = 10/2

Here, the denominator is about 5, so the quotient is about ...

  21.4 × 2/10 = 42.8/10 = 4.28 ≈ 4.3 . . . . . a first estimate; known to be low

We notice that 4.6 is 0.4 less than 5, which is 0.8/10 = 0.08, or 8% less. That means the actual quotient will be on the order of 8% more than 4.3.

A closer estimate would be ...

  4.3 + 0.08 · 4.3 = 4.3 +0.344 ≈ 4.64

An estimate of the quotient is 4.64.

__

Additional comment

To compute our "error correction," we rounded 4.28 up to 4.3, about 2 parts in 400, making that number (4.3) be about 0.5% high. The estimate of 1/0.92 ≈ 1.08 turns out to be about 0.7% low. This means an even better estimate would add 0.2%, or about 0.009, to the estimate we have, making it about 4.653. These second-order corrections are also slightly off. The actual quotient rounds to 4.652.

Doubling a number is so easy that we elected to keep all of the digits of the numerator when we did the division by 5. This gave a more satisfying 4.3 instead of 4 as the first estimate.

In the given question we have to find which polynomial should be added to [tex]3x^3 - 2x^2 + 3[/tex] to get the polynomial [tex]3x^2 +4[/tex].

A polynomial is a mathematical equation made up of variables, constants, and exponents that are mixed using addition, subtraction, multiplication, and division operations.

The rate of change of the hypotenuse is 9.5 inches per second.

The rate of change of the hypotenuse of a right triangle can be calculated using the Pythagorean theorem. The theorem states that for a right triangle with sides of length a, b, and c (where c is the hypotenuse), a2 + b2 = c2.

In this case, we know that the two legs are 3 inches and 4 inches, and that the short leg is increasing by 7 in/sec and the long leg is growing at 9 in/sec.

Using the Pythagorean theorem, we can calculate the rate of change of the hypotenuse. We can set up the equation as follows: c2 = 32 + 42, where c is the hypotenuse. Solving for c, we get: c = √(32 + 42).

To calculate the rate of change of the hypotenuse, we need to take the derivative of the equation. Taking the derivative of the equation, we get: c' = (7/2) * (3/c) + (9/2) * (4/c).

Plugging in our values, we get: c' = (7/2) * (3/5) + (9/2) * (4/5). Simplifying, we get: c' = 9.5 in/sec.

Therefore, the rate of change of the hypotenuse is 9.5 inches per second.

Probability without replacement refers to the likelihood of a specific event occurring when items are removed from a set or collection as they are selected. It differs from probability with replacement, where the items are replaced after each selection and the set remains unchanged.

To calculate probability without replacement, we use the formula:

P(Event) = Number of favorable outcomes / Number of possible outcomes

Where the number of possible outcomes is the total number of items in the set, and the number of favorable outcomes is the number of items that satisfy the conditions of the event.
