Answer:

Binomial distribution summarizes the number of trials, or observations when each trial has the same probability of attaining one particular value. The binomial distribution determines the probability of observing a specified number of successful outcomes in a specified number of trials.

Answer:

The binomial is a type of distribution that has two possible outcomes (the prefix “bi” means two, or twice). For example, a coin toss has only two possible outcomes: heads or tails and taking a test could have two possible outcomes: pass or fail. A Binomial Distribution shows either (S)uccess or (F)ailure.

Consider the line y=5/7x+7. Find the equation for the line that is parallel to the line and passes through the point (-5,-2). Fi

The parallel line:
y = mx + c
y = 5/7x + 7

Gradient of parallel line = 5/7

y = mx + c
y = 5/7x + c
-2 = (5/7 x -5) + c
-2 = -25/7 + c
-2 + 25/7 = c
c = 11/7

y = 5/7x + 11/7

The perpendicular line
y = mx + c
y = 5/7x + c
m = 5/7

Gradient of perpendicular line = -1/(5/7) = -7/5

y = mx + c
y = -7/5x + c
-2 = (-7/5 x -5) + c
-2 = 7 + c
-2 - 7 = c
c = -9

y = -7/5x - 9

Hello I need help with question 12! I will give you a great rating! Please help, I’m not sure how to do this. Also this is not a

Given the following question:

Lable all the sides of the triangle:

Hypotenuse is the missing side

Right angle is the opposite

Adjacent is equal to 21

We have all of our sides so now we won't get them mixed up when finding the missing value of this triangle.

sin =

opp/hyp

cos =

adj/hyp

tan =

opp/adj

Since we are given the adjacent side and we are trying to find the hypotenuse we will solve for cos since we have the adjacent side but we need the hypotenuse

cos(35)=21/x

Now solve:

$\begin{gathered} cos35^{\circ}=\frac{21}{x} \\ x\times x=0 \\ (x)cos35=21 \\ \frac{cos35}{cos35}=0 \\ \frac{21}{cos35}=25.6362664 \\ 25.6362664 \\ 3$
