Petra was given 12 yards of fabric to make costumes for the school play if each costume requires 1 1/2 yards how many costumes c

solmaris [256]

Petra can make 8 costumes with 12 yards of fabric

<h3><u>Solution:</u></h3>

Given that Petra was given 12 yards of fabric to make costumes for the school play

Each costume requires $1\frac{1}{2}$ yards

<em><u>To find: number of costume Petra can make</u></em>

The number of costume Petra can make is calculated by dividing the total fabric she has by fabric needed for one costume

$\text {number of costume Petra can make }=\frac{\text {total fabric she has }}{\text {fabric needed for one costume }}$

Total fabric she has = 12 yards

Fabric needed for 1 costume = $1\frac{1}{2} = \frac{2 \times 1 + 1}{2} = \frac{3}{2}$ yards

Therefore,

$\text {number of costume Petra can make }=\frac{12}{3 / 2}=\frac{12}{3} \times 2=8$

Thus petra can make 8 costumes with 12 yards of fabric

A manager finds a moderate negative correlation between the number of computer sales and the number of microwave sales in his st

BabaBlast [244]

Answer:

C) The correlation is most likely a coincidence.

Step-by-step explanation:

By general comprehension of the population and their buying habits, I don't think we can really establish a relation between the sales of computers and the microwaves in a general manner. If the store is located near a university residence and it's September, there might be a link to be done, but in general, no.

It's not like some enters a store and says "Ok, will I buy a microwave or a computer today?". Those are two totally different products, with different clienteles and different needs.
