Help on number two and plz

Answer:

x ≈ 7.7

Step-by-step explanation:

Using Pythagoras' identity on the right triangle on the right side

let the third side be y , then

y² + 4² = 10²

y² + 16 = 100 ( subtract 16 from both sides )

y² = 84

Using Pythagoras' identity on the right triangle on the left side

x² + 5² = y²

x² + 25 = 84 ( subtract 25 from both sides )

x² = 59 ( take the square root of both sides )

x = [tex]\sqrt{59}[/tex] ≈ 7.7 ( to the nearest tenth )

Answer:

Answer:

The percentage of males are not at least 172 pounds

P(X⁻ ≥ 172) = 0.26

Step-by-step explanation:

Step(i):-

Given that 74% of 19 -year -old males are at least 172 pounds

Let 'X' be a random variable in a binomial distribution

P( X≥172) = 74% = 0.74

we have to find that the percentage of males are not at least 172 pounds

Step(ii):-

The probability of males are not at least 172 pounds

P(X⁻≥172) = 1- P( X≥172)

                 = 1- 0.74

                 = 0.26

Final answer:-

The percentage of males are not at least 172 pounds

P(X⁻ ≥ 172) = 0.26

Answer:

It was -∞ < y < ∞

Step-by-step explanation:

None.

The range of the function is ( -∞ to +∞)

A function is a law that relates two variables namely, a dependent and an independent variable.

A function always has a defined range and domain, domain is all the value a function can have as input and range is all the value that a function can have.

The function is of various types, logarithmic, exponential, quadratic, radical, etc.

The function is shown in the image,

The function is a hyperbolic function, represented by x²/a² -y²/b² = 1 for a hyperbola having a center at the origin.

The function can give any value from the set of real numbers and so,

The range of the function is a set of real numbers.

Answer:

q = x + 3

Step-by-step explanation:

q = (x^2 + 7x + 12)          factor the numerator

    ============

         x + 4

q = (x + 3)(x + 4)

        ========

          (x + 4)

Notice that the x + 4's cancel

q = (x + 3)

Answer:

20v2−40v+20

Step-by-step explanation:

=(4v+−4)(5v+−5)

=(4v)(5v)+(4v)(−5)+(−4)(5v)+(−4)(−5)

=20v^2−20v−20v+20

= 20v^2-40v+20

You can easily do this by using the FOIL method.

F - first -  in this case, 4v and 5v

O - Outside - in this case, 4v and -5

I - Inside - in this case, -4 and 5v

L - Last - In this case, -4 and -5

Then you find the like terms and add them together and then you have your answer which is also in standard form.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants. An algebraic expression is a combination of variables, constants, and mathematical operations, such as addition, subtraction, multiplication, division, and exponentiation.

The variables represent unknown or unspecified values that can take on different numerical values, while the constants are specific, fixed values that do not change.

The mathematical operations are used to manipulate the variables and constants and to create different algebraic expressions.

Given expression ,

[tex](-3m^5)(–2m^4)[/tex]

we know that [tex]a^m * a ^n = a ^ (m+n)[/tex]

[tex](-3m^5)(-2m^4) = 6m^(5+4)[/tex]

= [tex]6m^9[/tex]

Therefore, the answer is [tex]6m^9[/tex] in standard form.

Answer:

DB!

Step-by-step explanation:

Because if you multiply them out, they both equal 6k-30.

-6(5-k)=-30+6k, which is equal to 6k-30.

Hope I helped!

because you can use the distributive property with

-6(5-k)

-6×5= -30

-6×-1k= 6k

so that equals 6k-30
