68% will be 1 standrd deviation either side of the mean so a reasonable estimate will be (25*0.68) / 2 = 8.5

Please help meeee I don't know this

Vanyuwa [196]

Answer:

$\boxed {m = -\frac{5}{7}}$

Step-by-step explanation:

Use the <u>Slope Formula</u> to determine the slope of two given points:

$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

First Point: $(x_{1} , y_{1})$

Second Point: $(x_{2}, y_{2})$

-Substitute both points:

First Point: $(5, 11)$

Second Point: $(19, -1)$

$m = \frac{-1 - 11}{19 - 5}$

-Solve for the slope:

$m = \frac{-1 - 11}{19 - 5}$

$m = \frac{-10}{14}$

$\boxed {m = -\frac{5}{7}}$

Therefore, the slope is $-\frac{5}{7}$

Solve the equation 24+0.44x=19+1.69x

vichka [17]

Answer: X= 4

Step-by-step explanation:

24+0.44x=19+1.69x exp equation like:

24+44x/100=19+169x/100

Multiply left and right side of equation with 100

2400+44x=1900+169x

2400-1900=169x-44x

500=125x

x=500/125

x=4
