Annabel is comparing the distances that two electric cars can travel after the battery is fully charged. Car A (miles) Car B (mi
Maslowich

Answer:

Car B can travel further than Car A after the battery is fully charged.

D. Car B because the measures of variability are smaller for Car B than for Car A.

Step-by-step explanation:

Car B can travel further than Car A after the battery is fully charged because Car A has lesser mean and median than Car B.

Median divides the data into two halves. A smaller median means that there is lesser mileage of Car A than Car B.

There are two measures.

Measure of center tells us how much near or far the data is spread from the center.

The mean , median and mode are the measures of center.

Car A has less mean , median telling us that it traveled less.

Measure of Variability tells us how data changes with a single value.

Smaller MAD means the data is denser at the mean. Car B has lesser MAD.

Smaller IQR tells us that data is closer to the middle of the data.

Car B has smaller IQR .

So car B traveled consistently as it has smaller IQR and MAD

D. Car B because the measures of variability are smaller for Car B than for Car A.

Confused, and there's a test tomorrow.
-BARSIC- [3]

Answer:

  12y +16yi

Step-by-step explanation:

The thing about complex numbers is that you can treat them as binomials and use all of the things you know about multiplying and factoring polynomials.

Here, we assume you have ...

  (5 +2yi)(4 -3i) -(5 -2yi)(4 -3i)

The factor (4 -3i) can be factored out, so you have ...

  = ((5 +2yi) -(5 -2yi))(4 -3i)

  = (4yi)(4 -3i)

  = 16yi -12yi²

At this point, the definition of i comes into play, and you replace i² with -1.

  = 12y +16yi

Mademuasel [1]

Answer:

<em> Anna's wand can cast 70 spells</em>

<em></em>

Step-by-step explanation:

Elsa's wand can cast 53 spells

her wand casts 17 fewer cells than her sister Anna's

Amount of spells cast by Anna's wand = ?

We write the question down in the form of an equation

x - 17 = 53

where x is the amount of spells Anna's wand can cast.

we then proceed to solve by collecting like terms to different sides of the equation. We'll have

x = 53 + 17

which leaves us with

x = 70

This means that<em> Anna's wand can cast 70 spells.</em>
