Step-by-step explanation:

If x = 0, 5x = 7x is true.

If x = 1, 5x ≠ 7x

5x = 7x is sometimes true.

Answer:

80

Step-by-step explanation:

12 is 15% of 80.

80 movies does the streaming service offer.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

A movie-streaming service offers 12 children's movies.

This is 15% of the total number of movies offered.

let the total number of movies offered be x.

So, 15% of x= 12

15/100 x = 12

x= 1200/15

x= 80

Thus, there were total 80 movies.

Answer:

About 2,800.

Step-by-step explanation:

2,000(1.05)^x

x =7.

2,000(1.05)^7

find 1.05 to the power of 7, which is 1.4071....

then times 1.4071... by 2,000. You will get 2,814.2 - or about 2,800.

The population of butterflies after 7 years will be approximately 2814 butterflies.

An exponential function is defined as a function whose value is a constant raised to the power of an argument is called an exponential function.

The formula f(x) = 2000(1.05)ˣ can be used to model the population of butterflies after x years, where x is a non-negative integer.

Here, the initial population is 2000.

To find the population of butterflies after 7 years, we can substitute x = 7 into the given function and evaluate:

f(7) = 2000(1.05)⁷

Using a calculator, we get:

f(7) ≈ 2814

Therefore, the population of butterflies after 7 years will be approximately 2814 butterflies.

Answer:

[tex]\lim_{x \to 2} \frac{x^{2} }{x^{2} +4} = \frac{1}{2} = f(C)[/tex]

The  function f(x) is continuous

Step-by-step explanation:

Explanation:-

Given that the function

                   [tex]f(x) = \frac{x^{2} }{x^{2} +4}[/tex]

    put  x = c =2

                 [tex]f(c) = f(2) = \frac{(2)^{2} }{(2)^{2} +4} = \frac{4}{8} = \frac{1}{2}[/tex]

              [tex]\lim_{x \to 2} \frac{x^{2} }{x^{2} +4} = \frac{2^{2} }{2^{2} +4} = \frac{4}{4+4} = \frac{4}{8}[/tex]

              [tex]\lim_{x \to 2} \frac{x^{2} }{x^{2} +4} = \frac{1}{2}[/tex]

Answer:

Probability = 0.12025

Step-by-step explanation:

P (Am) = 1/50 = 0.02       {Magazine ad}

P (At) = 1/8 = 0.125         {Television ad}

P (Am ∩ At ) = 1/100 = 0.01      {Both ads}

P (Am U At) = P (Am) + P (At) - P (Am ∩ At )

= 0.02 + 0.125 - 0.01

P (Am U At)  = 0.135       {Person sees either ad}

P (Am' ∩ At') = 1 - P (Am U At)

P (Am' ∩ At')  = 1 - 0.135 = 0.865      {Person sees none ad}

Prob (Purchase) = Prob (Purchase with ad) + Prob (purchase without ad)

P (P/ A) = 1/4 = 0.25 , P (P / A') = 1/10 = 0.1

P (P) = (0.25) (0.135) + (0.1) (0.865)

= 0.03375 + 0.0865

0.12025
