range = highest value - lowest value = answer

Range: 125 - 3 = 122

Interquartile Range: upper quartile - lower quartile = answer

Interquartile range: 23 - 16 = 7

lower quartile = 16

upper quartile = 23

Melissa used 4 cups of sugar to bake 54 cookies. If she’s only used 1 cup of sugar, what would be an equivalent ratio of cups to

daser333 [38]

Answer:

$\frac{2}{27}$

Step-by-step explanation:

We have given that melissa used 4 cups of sugar to bake 54 cookies.

That means 1 cup of sugar will be used to bake $\frac{54}{4}=\frac{27}{2}$ by unitary method

We have to find the ratio of cups to the cookies

We are using 1 cup of sugar

And cookies will be $\frac{27}{2}$

$\text{equivalent ratio}=\frac{1}{\frac{27}{2}}=\frac{2}{27}$

Jillian flew to New Zealand for summer vacation. While she was there, she rode her bike 1/3 of the time. She spent 1/4 of the re

Elis [28]

If the time she rode her bike is 24, then 24*3 would be the Whole time she was there. She was there for a total of 72 hours.
Subtract 24 from 72 because it's 1/3 and you need the other time.
You get 48.
You need to find 1/4 of 48, so you divide it by 4.
48/4 = 12.
She rides the train for 12 hours. This is 1/2 of a day, so your answer is:

She rides the train for 1/2 of a day.

The hexagon GIKMPR is regular. The dashed line segments form 30 degree angles.

Gwar [14]

Answer:

The correct option is (D).

Step-by-step explanation:

It is given that GIKMPR is regular hexagon. It means it has 6 vertices.

Since the central angle is 360 degree. Therefore the central angle between two consecutive vertices is

$\frac{360^{\circ} }{6}=60^{\circ}$

It is given that the dashed line segments form 30 degree angles.

We have rotated the hexagon about O to map PQ to RF. Since P and R are consecutive vertices, therefore the angle between them is 60 degree.

The vertex R is immediate next to the vertex P in clockwise direction.

So if we rotate the hexagon at 60 degree clockwise about O, then we can maps PQ to RF.

$360^{\circ}-60^{\circ}=300^{\circ}$

Therefore we can also rotate the hexagon at 300 degree counterclockwise about O, then we can maps PQ to RF.

Therefore option D is correct.

17. Which of the following is a graph of y= x^2?

Juli2301 [7.4K]

Answer:

The parabola - quadratic.

Step-by-step explanation:

There is only graph / option in the picture but it is the correct one. Regardless, whether x is a positive or negative, the y coordinate is going to be a positive number as x^2 will produce a positive. So as -x^2 will also be positive.
