Answer:

91

Step-by-step explanation:

The mean is calculated as

mean = \frac{sum}{count}

Given mean = 85 , then letting x be the 7th number

\frac{82+93+68+93+70+98+x}{7} = 85 ( multiply both sides by 7 )

504 + x = 595 ( subtract 504 from both sides )

x = 91

The 7th number is 91

Find the equation of the graphed line.
Tanzania [10]

Answer:

d. y = -⁷/6x - 7

Step-by-step explanation:

✔️First, find the slope (m) using two points on the line, (-6, 0) and (0, -7):

Slope (m) = change in y/change in x

Slope (m) = (-7 - 0)/(0 - (-6))

Slope (m) = -7/6

✔️Determine the y-intercept (b):

The line intercepts the y-axis at -7. Therefore,

b = -7.

✅To write the equation, substitute m = -⁷/6 and b = -7 into y = mx + b

Thus:

y = -⁷/6x + (-7)

y = -⁷/6x - 7

(2,1) and (3,6)

Slope = (6-1)/(3-2) = 5

y = mx + c
y = 5x + c

at point (2,1)
1 = 5(2) + c
1 = 10 + c
c = -9

y = 5x - 9
