Answer:
Stratified Sampling
Step-by-step explanation:
The given scenario corresponds to stratified sampling because the population is divided in to two strata and from each stratum a random sample of 50 teacher is selected. The stratified sampling involves the selection of random sample of sampling units from the strata constructed by dividing diverse population into similar groups. Here. in the given statement the population is "High School Teachers" which is divide into two strata "Male high school teacher" and "female high school teacher" and then selecting a random sample of size 50 from each stratum.
Hence the given situation corresponds to Stratified Sampling.
Answer:
dV(t)/dt = kV(t)
Step-by-step explanation:
Since the rate of change of the car’s value in dollars per year dV(t)/dt is proportional to the car’s value V(t), ten
dV(t)/dt ∝ V(t)
dV(t)/dt = kV(t)
Answer:
2
Step-by-step explanation:
Answer:
y = -5x-4
Step-by-step explanation:
start with slope-intercept form:
-9-11/1+3 = -20/4 = -5
your slope is -5
next, do point-slope form:
y+9 = -5(x-1)
y+9 = -5x+5
-9 -9
y = -5x-4
