Mathematics
1 answer:
Nikitich [7]2 years ago
3 0

Answer:

Option 4

The answer is 10.8

Step-by-step explanation:

5/6 = 9/c

5c = 9 × 6

5c = 54

5c/5 = 54/5

c = 10.8

Thus, The value of c is 10.8

<h3><u>For </u><u>Verification</u>;</h3>

5/6 = 9/c

5/6 = 9/10.8

0.833 = 0.833

Hence, L.H.S = R.H.S

You can mow one acre in 126 minutes. i can mow one acre in 117 minutes. how long will it take you to mow a 0.17-acre lawn? 13 in
Morgarella [4.7K]

a) (0.17 ac)×(126 min/ac) = 21.42 min

b) I can mow 1/126 ac/min; you can mow 1/117 ac/min. Together, we can mow at a rate that is the sum of these:

... (1/126 + 1/117) ac/min = (117 + 126)/(126×117) = 243/14,742 ac/min

Then it will take 14,742/243 min/ac × 0.17 ac/lawn ≈ 10.31 min/lawn

Sadie is saving for a new car. Below is the total amount of money in her savings account on the last day of each month. Show all
ICE Princess25 [194]


The mean is 10,724.28.



Explanation:


The mean is all of the values divided by the number of values there are.

So what you have to do is add all of the numbers and divide it by the amount of numbers there are.


10,150+10,211+10,424+10,769+10,884+11,155+11,477= 75,070.


Since there are 7 numbers, divide 75,070/7 and you get your mean, which is 10,724.28 rounded.

!HELP ASAP WOULD BE APPRECIATED! The expression to find the perimeter of a rectangle is 2(length + width). What is the perimeter
Andrews [41]

Answer:

ok im not sure this is the right answer to your specific question, because i dont understand the wording to well, but here...

for 1/7 and 1/2 it would be 2/7 and 1 (whole)

for 1 and 1/7 it would be 2(whole) and 2/7

for 1 and 2/7 it would be 2(whole) and 4/7

for 4/9 it would be 8/9 and x

and for 2/9 it would be 4/9 and x

sorry if thats not the question :)

EDIT: its the second one because

2*1/7= 2/7

and 1/2*2=1

. The estimate regression equation for a model involving two independent variables and 10 observations follows.y = 29.1270 + 0.5
beks73 [17]

Answer:

b) y = 289.815 when x_1 = 180 \text{ and } x_2 = 310

Step-by-step explanation:

We are given the following information in the question:

y = 29.1270 + 0.5906x_1 + 0.4980x_2

where y is the dependent variable,

x_1, x_2 are the independent variable.

The multiple regression equation is of the form:

y = b_0 + b_1x_1 + b_2x_2

where,

b_0: is the intercept of the equation and is the value of dependent variable when all the independent variable are zero.

b_1: It is the slope coefficient of the independent variable x_1.

b_2: It is the slope coefficient of the independent variable x_2.

  • The regression coefficient in multiple regression is the slope of the linear relationship between the dependent and the part of a predictor variable that is independent of all other predictor variables.

Comparing the equations, we get:

b_1 = 0.5906\\b_2 = 0.4980

  • This means holding x_2 constant, a change of one in x_1 is associated with a change of 0.5906 in the dependent variable.
  • This means holding x_1 constant, a change of 1 in x_2 is associated with a change of 0.4980 in the dependent variable.

b) We have to estimate the value of y

y = 29.1270 + 0.5906(180) + 0.4980(310) = 289.815
