MAVERICK [17]

Answer:

16/21 dresses

Step-by-step explanation:

3/4 · k hours: 4/7 · k dresses for any constant k

If we want 1 hour, then k will need to be 4/3

4/3 × 4/3 hours: 4/7 × 4/3

1 hour = 16/21 dresses

Answer:

The first and third quartiles were calculated incorrectly. Also, this means the inter quartile range is incorrect.

Step-by-step explanation:

The first quartile is going to be the median of the lower half of the data set {89, 93, 99, 110}  this median is (93+99)/2, or 96.

The third quartile can be calculated the same way with the data set {135, 144, 152, 159} This gives us 148 as the third quartile.

Lastly, the interquartile range is just the difference between the first and third quartiles, which is 52.

In △XYZ, m∠X = 27° and m∠Y = 48°. Which gives the sides of the triangle in order from shortest to longest?
Crazy boy [7]

Answer:

z, y and x

Step-by-step explanation:

Now, to answer this question, what we must know is that the side facing the largest angle is the largest while the side facing the smallest is the smallest.

What i’m saying in essence is that the bigger the angle faced, the larger the side.

Now since we have 3 angles in a triangle that adds up to 180

we have 27 and 48 already, the third side would be 180-27-48 = 105

So which side faces which angle?

Let’s have a diagrammatic representation of the said triangle.

Check this in the attachment please

The longest side is thus z, followed by y and lastly x
