Consider the following hypothesis test.

h0: μ1-μ2=0
ha: μ1-μ2 ! =0

the following results are from independent samples taken from two populations.
sample1 sample2
n1=80 n2=70
x1=104 x2=106
σ= 8.4 σ=7.6

a. what is the value of the test statistic?
b. what is the degrees of freedom for the t distribution?
c. what is the p-value?
d. at a = 0.05, what is your conclusion?

all but the second one

step-by-step explanation:

cuz that one goes over 180

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
