Find the missing coefficient.

y2 − [-5y − y(-7y − 9)] − [-y (15y + 4)] = 0

Answers

Answer 1
Answer: There is only one solution in the given equation -y2 − [-5y − y(-7y − 9)] − [-y (15y + 4)] = 0. In solving this problem, apply first PEMDAS (parenthesis, exponents,multiplication, division, addition, subtraction). Then equation will transform into -y2+5y-7y2-9y+15y2+4y=0. Combine terms with same power and achieve 7y2=0. Divide both sides with 7 and perform square root of zero. Since the root is zero, we have one solution of the given equation which is y=0.

The number of elements in the sample space of an event is equal to the total number of possible outcomes. A.True
B. False

Answers

Answer with explanation:

Meaning of Sample Space: Total number of Elements in an event when an experiment is done under same condition, several times and produce the same outcome every time.

For, example: Toss an Unbiased Coin, 100 or 1000 times, it will produce the same outcome every time which are Head and Tail.

Total Possible Outcome: Suppose In a Bag, there are 5 Red , 5 Green , and 6 Orange Color Balls.We want to draw a ball.So,Every time you draw a  ball from the bag, it will be either, Red, green or Yellow.So, total Possible outcome of balls in the bag, will be =5 Red +5 Green +6 Orange=16 Balls.

≡True Statement:⇒The number of elements in the sample space of an event is equal to the total number of possible outcomes.

What is the inverse of f(x) = The quantity of three x plus five, over seven.?

Answers

To solve for the inverse of the function, one way to go about it is to switch or reverse the variables for both x and y. Then solve for y or f(X) again.
F(X) = 3x+5/7
Y = 3x+5/7
X = 3y+5/7
7x = 3y+5
7x-5 = 3y+5-5
7x-5 = 3y
7x-5/3 = 3y/3
7x-5/3 = y
Y = 7x-5/3
F(x) = 7x-5/3.

7. PQ contains points Rand S such that PR, RS and SQ are respectively three consecutive evenintegers. If PQ is 54, find the length of the middle segment, RS

Answers

The length of the middle segment RS is determined as 18.

How to calculate the middle segment?

Let's assume that the three consecutive even integers are x, x + 2, and x + 4

So, the length of PR (x) + the length of RS (x + 2) + the length of SQ (x + 4) equals the total length of PQ (54).

Mathematically, this can be represented as:

x + (x + 2) + (x + 4) = 54

Now, let's solve for x:

3x + 6 = 54

Subtract 6 from both sides:

73x = 48

Now, divide by 3:

x = 16

So, the first even integer (PR) is 16, the second even integer (RS) is 16 + 2 = 18, and the third even integer (SQ) is 16 + 4 = 20.

Thus, the length of the middle segment RS is 18.

#SPJ3

Answer:

RS = 18

Step-by-step

PR = x

RS = x+2

SQ = x+4

x+(x+2)+(x+4)=54

3x+6=54

3x=48

x=16

PR = 16

RS = 18

SQ = 20
