WILL MARK BRAINLIEST IF CORRECT!! What is the difference between constructing a square and constructing an equilateral triangle?

A. For the square construction, the diameter will be used, but for the equilateral triangle construction, the radius will be used. B. For the square construction, the radius will be used, but for the equilateral triangle construction, the diameter will be used. C. The square construction will need two arcs along the circle, but the equilateral triangle construction will need two arcs above and two arcs below the diameter of the circle. D. The square construction will need three arcs along the circle, but the equilateral triangle construction will need two arcs above and two arcs below the diameter of the circle.

Answer:

$7.50

Step-by-step explanation:

4 bottles of water cost $10, meaning that each bottle costs $2.50 (10/4 = 2.5). If 3 bottles are bought and each bottle costs $2.50, the total cost is $7.50 (3*2.5 = 7.5).

ALGEBRA 2 QUESTION URGENT HELP PLEASE!!
NARA [144]

Answer:

d. the quantity of negative twenty plus sixteen i all over forty one.

Step-by-step explanation:

We want to simplify the complex number:

\frac{\sqrt{-16} }{(3-3i)+(1-2i)}

We rewrite to obtain:

\frac{\sqrt{16}\times \sqrt{-1} }{(3+1)+(-3i-2i)}

Recall that: \sqrt{-1}=i and  -1=i^2

We simplify to get:

\frac{4i}{4-5i}

We rationalize to get:

\frac{4i}{4-5i}\times\frac{4+5i}{4+5i}

\frac{4i(4+5i)}{(4-5i)(4+5i)}

\frac{16i+20i^2}{4^2+5^2}

\frac{16i-20}{16+25}

\frac{-20+16i}{41}

The correct answer is D

A spinner has 12 equal sectors. 4 sectors are coloured red, 3 are coloured blue, and 5 are coloured yellow. The pointer on the s
vodomira [7]

Answer:

3.70% probability of the pointer landing on red each time

Step-by-step explanation:

For each time that the pointer is spun, there are only two possible outcomes. Either it lands on red, or it does not. The probability that it lands on red on a spin is independent of other spins. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

12 sections, of which 4 are red.

This means that p = \frac{4}{12} = 0.3333

The pointer on the spinner is spun 3 times.

This means that n = 3

What is the probability of the pointer landing on red each time?

This is P(X = 3).

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 3) = C_{3,3}.(0.3333)^{3}.(0.6667)^{0} = 0.0370

3.70% probability of the pointer landing on red each time
