Answer: x = 11

Step-by-step explanation:

same as the last question, set them as equal and solve. here's my work:

5x - 1 = 4x + 10

5x - 1 (+ 1) = 4x + 10 (+ 1)

5x = 4x + 11

5x (- 4x) = 4x (- 4x) + 11

x = 11

AutoTrader would like to test if a difference exists in the age of three different types of vehicles currently on the road: truc

liubo4ka [24]

Answer:

Step-by-step explanation:

Remember that the general formula for SSTR is

$SSTR = n_1(\bar{x_1}-\bar{x})+...+n_k(\bar{x_k}-\bar{x})$

For this problem

$\bar{x} = 8$

$n_1 = n_2 = n_3 = n_4 = 4$

then

$n_1(\bar{x_1}-\bar{x})+...+n_k(\bar{x_k}-\bar{x}) = 32$

so once you have the SSTR then the MSTR is given by the following formula

$MSTR = \frac{SSTR}{t-1}$

where $t$ is the number of treatments, for this case the number of treatments is 3 so $t = 3$ and

$MSTR = \frac{32}{3-2} = \frac{32}{2} = 16$

PLZ HELP ME!!

P=4.50s is the equation to use to determine p ...
because i believe y=mx+c

in this case
y is the price (p)
m is 4.50
x is the number of sunglasses (s)
there is no constant (c)

so p=4.50s
