Which addition equation matches the number line

Alborosie

Answer:

$\frac{2}{3}+(-2\frac{1}{3})=-1 \frac{2}{3}$ is correct.

Step-by-step explanation:

The number line between two consecutive integers is divided into 3 intervals. This means each of these intervals is 1/3. For example, starting from 0 towards right the first small line is at 1/3, the next at 2/3 and then at 3/3 = 1.

Similarly, towards the left of 0, we have -1/3, -2/3 and then-1. Based on this data, we can find the end points of the given line

The location of right end point is 2/3
The location of left end point is $(-1\frac{2}{3} )$

The distance between two endpoints can be calculated as:

Right End point - Left End point

$=\frac{2}{3} - (-1\frac{2}{3})\\\\ =\frac{2}{3} + 1\frac{2}{3}\\\\ =\frac{2}{3}+\frac{5}{3}\\\\ =\frac{7}{3}\\\\ =2\frac{1}{3}$

So, the equation can be set up as:

$\frac{1}{3}-(-1\frac{2}{3})=2\frac{1}{3}\\\\ \frac{1}{3}= 2\frac{1}{3}+(-1\frac{2}{3})\\\\ \frac{1}{3}-2\frac{1}{3}=-1\frac{2}{3}\\\\ \frac{1}{3}+(-2\frac{1}{3})=-1\frac{2}{3}$

Which matches with the final option.

cestrela7 [59]

Answer:

(a) $\hat y=0.919+2.065x$

(b) 83.6%

Step-by-step explanation:

(a)

A least square regression line is to be formed for predicting beak heat loss, as a percent of total body heat loss, from temperature.

Use MS-Excel to form the regression line.

Go to Data → Data Analysis → Regression

A dialog box will open.

Select the X and Y variables.

Press OK.

The regression output is attached below.

The equation of the least‑squares regression line is:

$\hat y=0.919+2.065x$

(b)

The coefficient of determination R² specifies the percentage of the variance in the dependent variable (Y) that is forecasted or explained by linear regression and the forecaster variable (X, also recognized as the independent variable).

Consider the regression output attached below.

The R² value is 0.8360.

That is 83.6% of the variation in beak heat loss is explained by the straight‑line relationship with temperature.

Help me with this I will give brainliest

BaLLatris [955]

Answer:

see explanation

Step-by-step explanation:

both linear equations will have the form

y = mx + c ( m is the slope and c the y- intercept )

Chef Mate

c(n) = mn + c

calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (2, 14) and (x₂, y₂ ) = (3, 18.5) ← 2 ordered pairs from the table

m = $\frac{18.5-14}{3-2}$ = $\frac{4.5}{1}$ = 4.5 , then

c(n) = 4.5n + c ( n represents ounces )

To find c substitute any ordered pair from the table into c(n)

using (4, 23 )

23 = 18 + c ⇒ c = 23 - 18 = 5

c(n) = 4.5n + 5 ← equation for Chef Mate

--------------------------------------------------------------------

Similarly for Grocery Gourmet

g(n) = mn + c

using (2, 23 ) and (3, 27 ) to find m

m = $\frac{27-23}{3-2}$ = $\frac{4}{1}$ = 4 , then

g(n) = 4n + c

using (4, 31 ) to find c

31 = 16 + c ⇒ c = 31 - 16 = 15

g(n) = 4n + 15 ← equation for Grocery Gourmet

------------------------------------------------------------------

Equate the 2 equations to find when cost is the same

4.5n + 5 = 4n + 15 ( subtract 4n from both sides )

0.5n + 5 = 15 ( subtract 5 from both sides )

0.5n = 10 ( divide both sides by 0.5 )

n = 20

Then when n = 20

c(n) = 4.5(20) + 5 = 90 + 5 = 95

g(n) = 4(20) + 15 = 80 + 15 = 95

Both Chef Mate and Grocery Gourmet charge $95 for 20 ounces of extract
