Answer:

54

Step-by-step explanation:

Assuming you mean a typical 7-day week... then 378 shipments in one week is the same as 378 shipments in 7 days.

To find a unit rate of shipments per day... simply divide 378 shipments by the 7 days

378 shipments/ 7 days = 54 shipments per day

The exponential regression equation is y = 172.21(0.99)ˣ and at x = 60 minutes y = 94.22 degree Fahrenheit and at x = 240 minutes y = 15.43 degree Fahrenheit.

<h3>What is correlation?</h3>

It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.

\rm r = \dfrac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{{[n\sum x^2- (\sum x)^2]}}\sqrt{[n\sum y^2- (\sum y)^2]}}

We have data shown in the table:

We can find the exponential regression equation using the data shown.

\rm y = ab^x

After calculating from the data:

a = 172.21 and b = 0.99

\rm y = 172.21(0.99)^x

The correlation coefficient will be:

r = -0.99

The range will be all real numbers.

The domain will be y > 0

As we can see in the graph x ∈R and y>0

After an hour,

Plug x = 60 minutes in the exponential regression equation:

\rm y = 172.21(0.99)^{60}

y = 94.22 degree Fahrenheit

After 4 hours, plug x = 240

\rm y = 172.21(0.99)^{240}

y = 15.43 degree Fahrenheit

 

Similarly, we can find any data from the exponential regression equation.

Thus, the exponential regression equation is y = 172.21(0.99)ˣ and at x = 60 minutes y = 94.22 degree Fahrenheit and at x = 240 minutes y = 15.43 degree Fahrenheit.

What is the equation of the line that passes through the point (5,-2)and has a slope of the fraction 6/5?
Tju [1.3M]

Answer:

6x-5y-40 = 0

Step-by-step explanation:

y-(-2)=6/5(x-5)

5(y+2)= 6(x-5)

5y+10 =6x-30

6x-5y-40 = 0

6x-5y-40 = 0 is the answer

The price of one sack of rice is Rs. 1,850.if wages charge Rs. 70 was added, find it price.​
Yuliya22 [10]

Answer:

The total price of the Rice sack is Rs 1920.

Step-by-step explanation:

The price of 1 sack of rice = Rs. 1,850

Wages Charge = Rs. 70

Now, the total price = Price of the Rice + Wages Charge

= Rs. 1,850 + Rs. 70

= Rs. 1920

or,  the total price = Rs. 1920

Hence, the total price of the Rice sack is Rs 1920.

Help how do you do this help fast please
GalinKa [24]

Answer:

x= 50°

Hope it helps!

Step-by-step explanation:

The sum of the exterior angles of a polygon is always 360°

So, x+40+x+20+2x+2x = 360

6x + 60= 360

6x = 360-60 = 300

6x= 300

x= 300/6

= 50
