Find the sum of the arithmetic series where n = 50, a = 9, and t50 = 331.

Answer:

D. 0.53

Step-by-step explanation:

California = 90

Total of those who prefer Brand A = 170

To find the percentage, you do:

90/170 × 100 = 52.941...

However you have to round it to two decimal points, hence you do:

52.941 ≈ 53%

53% = 0.53

This is due to 53% representing 53/100 = 0.53

Therefore, the probability that the person that likes brand A is from California is 0.53

The given 4th degree polynomial is ,[tex]f(x)=(x+5)(x+1)^2(x-2)[/tex] zeroes of the equation are -5,-1,2

A fourth-degree polynomial, or quartic function, is one that has a variable raised to the fourth power as its highest order term.

If the highest order term is positive or negative, a fourth-degree polynomial's graph will frequently resemble a M or a W.

The function will reach infinity on both sides if the leading term's coefficient, a, is positive.

The function will extend to minus infinity on both sides if the coefficient an is negative.

The function's y-intercept, or the point at which the function crosses the y-axis, is indicated by the word a0. The x-intercepts are revealed by the function's roots.

Inflection Points are roots of double derivate equation.

Given;

From the graph, x-intercepts are -5,-1,2.

That gives us (x+5),(x+1),(x-2) are factors of the function;

As at [tex]x=-1[/tex] graph touches x axis (x+1) is a double factor of f(x)

That leaves us with [tex](x+5),(x+1)^2,(x-2)[/tex] as factors of f(x);

[tex]f(x)=(x+5)(x+1)^2(x-2)[/tex];

From graph inflections points are -2.686,0.186;

That gives [tex]f^|^|(x)=(x+2.686)(x-0.186)[/tex]

What is a graph?

A relation is a specific instance of a function graph. A function is truly equivalent to its graph in set theory and the current mathematical underpinnings.

It is frequently more helpful to think about functions as mappings, which include the sets that constitute the domain and the codomain in addition to the relationship between input and output. For instance, the codomain should be considered while determining if a function is onto (surjective) or not. The codomain of a function is not determined by the graph alone.

It is typical to use the phrases function and graph of a function interchangeably since, although referring to the same thing, they suggest distinct ways of looking at it.

1)

let   y=0

0=(x+4)(x-1)

i.e. x = -4 and -1

2)

Let x =0

y=(0+4)(0-1)

y=-4

3)

Let x = 2

y=(2+4)(2-1)

y=6

4)

Let x = -3

D. 4⁵

An exponent refers to the number of times a number is multiplied by itself. For example, 2 to the 3rd (written like this: 23) means: 2 x 2 x 2 = 8. 23 is not the same as 2 x 3 = 6. Remember that a number raised to the power of 1 is itself.

here, we have,

We have to calculate to find the result -

The expression is = 4^(-3)/4^(-8)

According to the indices rule, the power will be deducted if it is a division.

Therefore, a^m/a^n = a^(m-n)

Using that formula,

4⁻³ / 4⁻⁸

= 4⁸ / 4³

= 4⁽⁸⁻³⁾

=4⁵

Therefore, the answer choice D is the option, and the answer is 4^5.

Option A is also correct.

Because we can find 4^5 with the help of that option.

Alternative way,

Step-by-step explanation:

a. The equation for the cost of AT&T would be $100 + $15n, where n is the number of phones on the account. The equation for the cost of Sprint would be $200.

We can graph these equations on a coordinate plane with the x-axis representing the number of phones on the account and the y-axis representing the monthly cost. The graph for the cost of AT&T would be a straight line starting at the point (0,100) and going through the point (1,115), (2,130), etc. The graph for the cost of Sprint would be a horizontal line at the y-coordinate of 200.

b. In order to determine which company would be cheaper for Carly's family, we can simply plug in the number of phones they have (5) into each of the equations we derived in part a. This would give us a cost of $200 for AT&T and $200 for Sprint. In this case, both companies would be equally cheap for Carly's family.

Alternatively, we could graph the equations and see which company's line is lower on the y-axis for the given number of phones (5). This would also show that both companies would be equally cheap for Carly's family in this case.

A has the larger standard devlation.

What is standard devlation?

The standard deviation is a statistic that expresses how much variation or dispersion there is in a set of values. While a high standard deviation suggests that the values are dispersed over a wider range, a low standard deviation suggests that the values tend to be close to the set mean.

We are given two plots of normal distributions A and B.

The mean of a normal distribution is located at the center of the plot.

Since the centers of both of the normal distributions A and B seems to be aligned, therefore, they both seems to have equal means.

The standard deviation basically determines the shape of the distribution.

As you can see, the normal distribution A is more spread out and thus has a larger standard deviation than normal distribution B.

Therefore, the two correct options are

• The means of A and B are equal.

• A has larger standard deviation.

What is a linear equation?

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."

Here, we have

Given:

t = the number of years after 1990.

So, for 1990, t = 0. So the coordinate is (0, 123000).

For 2007, t = 17. So the coordinate is (17, 215500).

Slope = (215500 - 123000)/17

Slope = 5441

P = 5441t + b,

b = 123000

P = 5441t + 123000
