Answer:

Step-by-step explanation:

On a two-way frequency table, marginal frequency can be obtained by adding the values of each of the two individual rows separately and obtain the total for each; and adding the values of each of the two individual columns separately rows and obtain the total for each. In the end, the column addition of the total of each of the separate two rows and row addition of the separate two columns must be equal at the lower bottom right corner.

Based on the above, option C. is the two-way frequency table that correctly shows the marginal frequencies.

How do you write 0.4 in simplest form

Sergeeva-Olga [200]

Well first you have to get 0.4 and turn that decimal into a fraction which will be 2/5 and that fraction is already at its simplest form and cant be reduced so your answer is both 0.4 and 2/5.

What is the value of the equation 3x-4y=65 when y=4

Inga [223]

4x4=16. So think of it like this now..
3x-16=65

Add 16 in each side and you get 3x=81. Divide 3 with 81 and should be 27, or x=27.
Then you check it by putting in the #'s

3(27)-4(4)=65
81-16=65
65=65 ✔️

I WILL GIVE BRAINLIEST....PLEASE HELP..........

REY [17]

Answer: The correct table which represents relationship B is,

Time (min) 1 3 8 9

Temperature (°C) 54.2 59.0 71.0 73.4

Step-by-step explanation:

Since, It is given that, table represents Relationship A.

Time (min) 1 3 8 9

Temperature (°C) 53.6 58.4 70.4 72.8

And, According to the question, Relationship B has a greater rate than Relationship A.

Therefore, for a particular time Relationship B must be given the greater value than relationship A.

Thus In 1 minute, The temperature by B > 53.6°

In 3 minutes, The temperature by relationship B> 58.4°

In 8 minutes, The temperature by relationship B> 70.4°

In 9 minutes, The temperature by relationship B> 72.8°

But when we apply this we found only Fourth table is following the above conditions.

Therefore, The table,

Time (min) 1 3 8 9

Temperature (°C) 54.2 59.0 71.0 73.4

represented by fourth option will be the correct table for relationship B.

Consider the equation y = a - bx. If y = 6 when x = 1 and y = 0 when x = 2, find . = х

Trava [24]

Answer:

see explanation

Step-by-step explanation:

(a)

y = $\frac{a}{x}$ - bx

substitute y = 6 , x = 1 into the equation

6 = a - b → (1)

substitute y = 0 , x = 2 into the equation

0 = $\frac{a}{2}$ - 2b ( multiply through by 2 to clear the fraction )

0 = a - 4b → (2)

multiply (1) by - 4

- 24 = - 4a + 4b → (3)

add (2) and (3) term by term to eliminate b

- 24 = - 3a + 0

- 24 = - 3a ( divide both sides by - 3 )

8 = a

substitute a = 8 into (1) and solve for b

6 = 8 - b ( subtract 8 from both sides )

- 2 = - b ( multiply both sides by - 1 )

2 = b

Then a = 8 and b = 2

(b)

when x = 4

y = $\frac{8}{4}$ - 2(2) = 2 - 4 = - 2
