Arepeated-measures research study uses a total of 20 participants to compare two treatment conditions. if the results are used to construct a 95% confidence interval for the population mean difference, then the t values will bea) ±2.093b) ±2.861c) ±1.729d) ±2.539

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

answer: 8d

step-by-step explanation:

45+5= 50+5=55+5=60

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
