<h3>Answer:</h3>

-1

<h3>Step-by-step explanation:</h3>

We are given:

a₁ = -17

a₁₃ = -29

Solving for the Common Difference (d):

We know that the formula for an AP is:

aₙ = a₁ + (n-1)d

The formula for the third term will be:

a₁₃ = a₁ + (13 - 1)d

replacing the given values:

-29 = -17 + (12)d

-12 = 12d [adding 17 on both sides]

d = -1 [dividing both sides by 12]

Hence, the common difference is -1

You are dealt two cards successively (without replacement) from a shuffled deck of 52 playing cards. find the probability that b

Rasek [7]

Answer:

$\frac{25}{102}$ .

Step-by-step explanation:

Total number of cards in a deck = 52

number of black cards in a deck = 26

Find the probability that both cards are black (without replacement).

Therefore, both events are dependent.

The probability of first card is black = $P_{1}=\frac{26}{52}$

the probability of second card is black = $P_{2}=\frac{25}{51}$

$P=\frac{26}{52}$ × $=\frac{25}{51}$

= $\frac{1}{2}$ × $\frac{25}{51}$

= $\frac{25}{102}$

The probability that both cards are black is $\frac{25}{102}$ .

A pizza company is building a rectangular solid box to be able to deliver personal pan pizzas. The pizza company wants the volum

ladessa [460]

Here, we are required to determine the width of the delivery box given the dimensions as in the question.

The correct answer is choice A.

The width of the delivery box is ; w = 7.

A rectangular box had the shape of a cuboid.

Volume of a cuboid = Length × width × height

width = w

Length = 2w - 6

height = w - 2

280 = (w) × (2w - 6) × (w - 2)

280 = (2w² - 6w) × (w - 2)

280 = 2w³ - 4w² - 6w² + 12w

280 = 2w³ - 10w² + 12w

2w³ - 10w² + 12w - 280 = 0

Therefore, w³ - 5w² + 6w - 140 = 0

By testing hypothesis at w = 7, i.e (w - 7) is a factor.

The expression cam be factorized as;

(w - 7)(w² +2w + 20) = 0.

Therefore, the only real solution of w is , w = 7.

Total miles= rate x time

We can set up 2 eq:
24=(x+8)(y-4)
24=xy

Where x is equal to my original rate
and y is equal to the original time spent traveling the 2mi

We can now solve for one of the variables and find our rate
