If 0.65 AU equal 1 inch how much would 0.05 AU equal and explain.
mart [117]

Answer:

0.05 AU corresponds to the 0.0769 Inches(<em>This calculation is not possible in real time world)</em>

Step-by-step explanation:

Given:

0.65 corresponds to 1 inch

To Find:

0.05 AU corresponds to how many inches.

Solution:

<em>The AU is astronomical unit which is preferred as the mean distance between  earth and sun.</em>

<em>AU is too big unit and used in space distance calculation.</em>

But here for  mathematical calculation,

0.65 AU corresponds to 1 inch

then 0.05 AU corresponds to  x inch(es)

Now cross multiplying the quantities we get ,

0.65x=0.05*1

x=0.05/0.65

x=0.0769 inches corresponds to 0.05 AU

(Preferred for this example only)

<em>(Remember that this calculation is hypothetical and practically incorrect to use it).</em>

Write a paragraph comparing the two classes' semester grades. Be sure to compare the extremes, the quartiles, the medians, and t
NISA [10]

Answer:

Class second have higher score and have greater spread.

Step-by-step explanation:

For first box plot

\text{Minimum value }= 53

Q_1=62

Median=80

Q_3=86

\text{Maximum value }= 89

Range=Maximum-Minimum=89-53=36

IQR=Q_3-Q-1=86-62=24

For second box plot

\text{Minimum value }= 56

Q_1=62

Median=74

Q_3=89

\text{Maximum value }= 96

Range=Maximum-Minimum=96-56=40

IQR=Q_3-Q-1=89-62=27

First class has greater minimum value, it means first class has lower grades.

First quartile of both classes are same, it means equal number students in both classes have less than 62 marks.

First class has greater median.

second class has greater third quartile.

Second class has greater Maximum value.  It means second class have higher score than first class.

Second class has greater range. It means the data of second class has greater spread.

Second class has greater inter quartile range.  It means the data of second class has greater spread.

Therefore, the class second have higher score and have greater spread.

Find the value of x in each of the given figures.
Kaylis [27]

Answer:

Step-by-step explanation:

1) Given figure is a parallelogram

Area = 144 cm²

base  * altitude = 144

16 * x = 144

x =144/16

x = 9 cm

2)2) Trapezium

Area = \frac{a+b}{2}*h      ; {a and b are parallel sides of trapezium}

( 37 +27 /2) * x  = 480 cm²

64/2 * h = 480

32 *  h = 480

h = 480/32

h = 15 cm

Which equation represents the relationship between x and y shown in the table?
Hunter-Best [27]

Answer:

y=2x-3

Explanation:

which equation represents the relationship between x and y shown in the table?

x | y

2 | 1

4 | 5

6 | 9

8 | 13

take a look at the values in the table one more,

we find the gradient of the line to be

G=y2-y1/(x2-x1)

G=13-1/(8-2)

slope/gradient=12/6

m=2

from equation of a line graph, we know

y=mx+c

m=gradient

c=intercept

y=vertical axis

x=a point on the horizontal axis

y=2x+c

when x=6, y=9

9=2(6)+C

c=-3

Therefore the equation becomes

y=2x-3
