Fwam surveyed 540 of the students in his school about their favorite color. students could choose between red and blue. 55% said
Digiron [165]

Answer:

243 students' favorite color is red

Step-by-step explanation:

if 55% of the students said their favorite color was blue, then 45% chose that red was their favorite color

we can get 45% of 540 using a cross-multiplication equation

45% is 45/100

45/100 is to ?/540

the (?) represents the value of students who chose red as their favorite color (we do not know this but we can figure it out using cross-multiplication)

45 times 540 is 24300

24300/100 = 243.

Give brainliest, please!

hope this helps :)

What are the domain and range of f(x)=log(x-1)+2?
marta [7]

Answer: Domain = (-1, \infty)

Range = (-\infty, \infty)

Step-by-step explanation:

Here, the given function,

f(x) = log(x-1) + 2

Since log( negative number ) = not defined

Also,

log(0) = -\infty

Hence, f(x) is defined if x - 1 > 0

⇒ x > 1

Thus, f(x) is defined for all the values that are greater than 1,

⇒ Domain of f(x) = All real number greater than 1,

= (1, \infty)

Now, for the interval (1, \infty),

f(x) can be any real number.

Thus, the range of the given function = (-\infty, \infty)

If v = 6i + 3j, what is ||-10v||
tia_tia [17]

The values of ||-10v|| is 51.96 units

  • Complex numbers are square roots of negative numbers. They are expressions that consist of both the real and imaginary axis.

  • The general form of a complex number is expressed as z = x + iy

Given the complex number v = 6i + 3j,

10v is expressed as 10(6i + 3j)

10(6i + 3j) = 60i + 30j

Take the modulus of the complex number:

|10v|=\sqrt{60^2+30^2}\\|10v|= \sqrt{1800+900}\\|10v|= \sqrt{2700} \\|10v|=51.96units

Hence the values of ||-10v|| is 51.96 units
