7 0

If you would like to solve the equation - 7 * x - 3 * x + 2 = 8 * x - 8, you can calculate this using the following steps:

- 7 * x - 3 * x + 2 = 8 * x - 8
- 7 * x - 3 * x - 8 * x = - 8 - 2
- 18 * x = - 10 /(-18)
x = 10 / 18
x = 5/9

The correct result would be 5/9.

Combine like terms.

-7x - 3x = -10x
-10x + 2 = 8x - 8
+10x +10x

2 = 18x - 8
+8 +8

10 = 18x

18x/18 = 10/18
x = 5/9

following frequency distribution shows the daily expenditure on milk of 30 households in a locality:Daily expenditure on milk(in

valina [46]

Note: As you missed to identify what we have to find in this question. But, after a little research, I am able to find that we had to find the Mode for the data given in your question. So, I am assuming we have to calculate the the Mode. Hopefully, it would clear your concept regarding this topic.

Answer:

The mode of the data = 75

Step-by-step explanation:

Lets visualize the given data in a table to show the frequency distribution:

Daily expenditure on milk (in Rs) Number of households

0-30 5

30-60 6

60-90 9

90-120 6

120-150 4

Here the maximum frequency is 9.

So, modal class is 60-90.

As the formula to calculate the mode:

$Mode = l_{1} + h (\frac{f_{1}-f_{0}}{2f_{1}-f_{0}-f_{2}} )$

Here, the maximum

$l_{1} =60, f_{1} =9, f_{0}=6, f_{0}=6, h=30$

$l=$ is the lower limit of the class

$f_{1} =$ is the frequency of the modal class

$f_{0} =$ is the frequency of the previous modal class

$f_{2} =$ is the frequency of the next previous modal class

$l=$ is the class size

So,

$Mode = l_{1} + h (\frac{f_{1}-f_{0}}{2f_{1}-f_{0}-f_{2}} )$

$Mode = 60 + 30 (\frac{9-6}{2(9)-6-6} )$

$Mode = 60 + \frac{(30)(3)}{6}$

$Mode = 60 + 15=75$

∴ The mode of the data = 75

Two points sit on a line with the following coordinates p(2,2) and Q(3,7) which is the distance from p to q

Alja [10]

ANSWER

$\sqrt{26}$

EXPLANATION

Given the coordinates p(2,2) and Q(3,7),

we can use the distance formula to find the distance between P and Q.

The distance formula is given by,

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

We substitute the coordinates to get,

$d=\sqrt{(3-2)^2+(7-2)^2}$

$d=\sqrt{(1)^2+(5)^2}$

$d=\sqrt{1+25}$

$d=\sqrt{26}$

Finding what percent one number is of another ?

Leto [7]

Answer:

11) 67%; 12) 25%

Step-by-step explanation:

Problem 11: Find the fraction representing 30 out of a total of 45, and then multiply the result by 100%:

30/45 = 2/3 = 0.67; then we see that 30 is 67% of 45.

Problem 12: Same method:

16/64 = 1/4 = 0.25. Mult. this by 100%: 16 is 25% of 64.

You've flipped the coin 3 times, and it has come up heads once. The cumulative fraction of heads is currently 1/3. If you flip t

Contact [7]

Answer:

Maybe. Either 2/4 or 1/4.

Step-by-step explanation:

If you flip a coin 100 times, ABOUT 50 percent will be heads up. Therefore it's not unlikely it up land heads up 2 out of 4 times, but its not unlikely it will be heads down either.
