Arielle has a collection of grasshoppers and crickets. She has 561 insects in all. The number of grasshoppers is twice the numbe

Daniel [21]

Answer:

<em>Arielle has 374 grasshoppers and 187 crickets</em>

Step-by-step explanation:

Let's set:

x = number of grasshoppers

y = number of crickets

Arielle has a collection of 561 insects, thus:

x + y = 561 [1]

The number of grasshoppers is twice the number of crickets, thus:

x = 2y [2]

Substituting [2] in [1]:

2y + y = 561

Simplifying:

3y = 561

Dividing by 3:

y = 561/3

y = 187

From [2]:

x = 2*187 = 374

x = 374

Arielle has 374 grasshoppers and 187 crickets

Help me plisssssssssssss

Answer:

cos theta = adja/ hypo

adja=8

hypo=17

cos theta= 8/17=0.47

theta= cos^-1 0.47

theta=1.0815

to fine missing side, use Pythagoras

hypo²= oppo² + adja²

17²= oppo² + 8²

289-64=oppo²

oppo²=225

oppo=15

Use the regression calculator to compare the teams’ number of runs with their number of wins. a 2-column table with 9 rows. colu

The equation of the trend line is ŷ = 0.15x - 23.21

<h3>How to determine the average rate of change of the trend line?</h3>

The points are given as:

hr =>808, 768, 655, 684, 637, 619, 613, 609, 563

w => 93, 94, 66, 81, 86, 75, 61, 69, 55.

Using a graphing calculator, we have the following calculation summary:

Sum of X = 5956
Sum of Y = 680
Mean X = 661.7778
Mean Y = 75.5556
Sum of squares (SSX) = 50569.5556
Sum of products (SP) = 7547.1111

The regression equation is represented as:

ŷ = bX + a

Where:

b = SP/SSX

b = 7547.11/50569.56

b = 0.14924

a = MY - bMX

a = 75.56 - (0.15*661.78)

a = -23.20961

This gives

ŷ = 0.14924X - 23.20961

Approximate

ŷ = 0.15x - 23.21

Hence, the equation of the trend line is ŷ = 0.15x - 23.21
