Answer:

\Huge\boxed{\mathsf{\frac{1}{26} }}

Step-by-step explanation:

<em><u>SLOPE FORMULA:</u></em>

\longrightarrow \displaystyle \mathsf{\frac{Y_2-Y_1}{X_2-X_1} }}

Y₂=(-15)

Y₁=(-16)

X₂=(-7)

X₁=19

Solve.

\displaystyle \mathsf{\frac{(-15)-(-16)}{(-7)-19}=\frac{(-15)+16}{(-7)-19}=\frac{1}{-26}=\boxed{\mathsf{\frac{1}{26}} }   }}}}

So, the slope is 1/26.

State. Probability sampling vs. non probability sampling​
Savatey [412]

Probability sampling simply illustrates a scenario where the subjects of the population have an equal opportunity.

<h3>What is probability sampling?</h3>

Probability simply means the likelihood of the occurence of an event.

In this case, in probability sampling, the subjects of the population have an equal opportunity.

In non-sampling, an equal opportunity isn't given.

What is a simpler form of the following expressions?
nadezda [96]

Answer:

D. 49p² - 64

Step-by-step explanation:

(7p - 8)(7p + 8)

Solving this requires the 'difference of squares' concept which states;

If (a - b)(a + b)

Then the solution must be a² - b²

Considering (7p - 8)(7p + 8) then the answer is;

(7p)² - 8² = 49p² - 64

What is the solution to this equation? <br> log_7 (5 + 11x) = 2
11111nata11111 [884]

Answer:

x = 4

Step-by-step explanation:

Using the rule of logarithms

log_{b} x = n , then x = b^{n}

Given

log_{7} (5 + 11x) = 2 , then

5 + 11x = 7² = 49 ( subtract 5 from both sides )

11x = 44 ( divide both sides by 11 )

x = 4

There are 14 teams in a basketball league.
Talja [164]

Answer:

Step-by-step explanation:

Given that :

Number of teams = 14

Each team plays every other team twice ;

Using the combination formula :

nCr = n! ÷ (n-r)! r!

14C2 = 14! ÷ (14 - 2)! 2!

14C2 = 14! ÷ (12)! 2!

14C2 = (14 * 13) ÷ 2 * 1

14C2 = 182 / 2

14C2 = 91

Hence, since they are going to be playing each other twice :

2(14C2)

2 * 91 = 182games
