JK and KL make up line JL.

JL = 2x + 8, JK = 2x - 2, KL = x - 9

If JK and KL make up line JL:

JK + KL = JL

We are solving for KL, so isolate it.

JK - JK + KL = JL - JK
KL = JL - JK
x - 9 = 2x + 8 - (2x - 2)
x - 9 = 2x - 2x + 8 + 2
x - 9 = 10

Often times, we would solve for x, but considering x - 9 is what we wanted the solution to anyway, we don't need to bother solving for x.

KL = 10

The derivative of the given function is 4x³ / (x²+1) ²

What is derivative mean?

d(u/v) = [ u(dv/dx) + v(du/dx) ] / v²

Given:

f(x) = x²/x²+1

Applying the formulae:

=  x²[ d(x²+1)/dx] + (x²+1) [ d(x²)/dx ] / (x²+1) ²

= x²(2x+0) + (x²+1)2x / (x²+1) ²

= 2x³ + 2x³ / (x²+1) ²

= 4x³ / (x²+1)²

Answer:A

Step-by-step explanation:

N is a lie, its increasing

Q is linear

R is linear

P must be true

Answer:

The answer is A) In Section P, the function is linear and increasing.

Step-by-step explanation:

B is false because it is not decreasing

C is false because it is considered linear (linear is a line). Non-linear is typically a curved line.

D is false because it's not increasing or decreasing, so when it states decreasing it isn't even right.

(a) The common ratio R is 3/10.

What do you mean by Geometric progression?

Every following word in a sequence known as a geometric progression (GP) is created by multiplying every previous term by a constant amount, or "common ratio." Another name for this progression is a pattern-following geometric sequence of numbers.

To find out the common ratio we have to divide the second term by the first term,

in the given example to find out the common ratio we have to divide [tex]P_{2[/tex] by  [tex]P_{1}[/tex],

so, we are getting, common ratio(R)= 9/30

                                                          =  3/10

Hence,The common ratio(R) is 3/10.

Examining the rainfall data for the two periods a conclusion is that the range of the values are period 1 has low variability while period 2 has high variability

period 1: 0.6

period 2: 4

The range in statistics refers to the distribution of data between the lowest and greatest value in the distribution. It is a widely used indicator of variation.

Measurements of variability provide you with descriptive statistics for summarizing your data set in addition to measures of central tendency.

By deducting the lowest value from the greatest value, the range is computed. A short range indicates low variability in a distribution, whereas a big range denotes significant variability.

The range is

Answer: The ratio of the total number of marbles in Orlandria’s marble collection is 7:28, where 7 is the yellow marbles and 28 is the total number of marbles Orlandria has.

The number is defined by the two inequalities:

x > -3

x  ≤ -6

If we define x as the number, the number increased by 3 is written as:

x + 3

If this is greater than zero or less than or equal to negative three, we can write two inequalities:

x + 3 > 0

x + 3 ≤ -3

Solving both inequalities for x (isolting it) we will get:

x > 0 - 3

x > -3

and:

x  ≤ -3 - 3

x  ≤ -6

So we have the two inequalities that define the number:

p is probability of success

n is number of trials

x = the number of expected successful outcomes

We are given;

p = 38% = 0.38

n = 10

Thus;

a) Probability that the number of college students who say they use credit cards because of the rewards program is​ exactly​ two is;

P(X = 2) = 10C2 * 0.38^(2) * (1 - 0.38)^(10 - 2)

P(X = 2) = 0.1419

b) Probability that the number of college students who say they use credit cards because of the rewards program is​ more than two is;

Answer: 1/8, Division equation: 1/3 divided by 8/3

Step-by-step explanation:

Step 1: Write this problem as an equation, of means multiply so the equation is 1/3 x 3/8.

Step 2: Solve the equation by multiplying the numerators and the denominators. You get 3/24.

Step 3: Simplify by dividing the numerator and denominator by their gcf. In this case it is 3. So, 1/3 of 3/8 is 1/8.

Step 4: Now we need to get the division equation of 1/3 x 3/8, for this you do the same thing as if we had to actually solve the division equation with fraction, just for changing multiplication to division instead. I am talking about keep change flip. You keep the first fraction the same. you change the operation to it's opposite ,and you flip the numerator and denominator in the second fraction. When we do this we get our division equation of 1/3 divided by 8/3.

Answer:

46/273

Step-by-step explanation:

To add fractions, they must have a common denominator. To set one, find a common multiple of both denominators. Simply multiply them together if it proves difficult.

7 x 39 = 253

Now set the denominators to this number and multiply the numerators by the opposite fraction's denominator.

39/259 + 7/253 = 46/253
This simplifies to 2/11

So, 1/3 + 1/39 = 2/11

Each  player will get 9 cards.

According to our question-
