Answer:
524880
Step-by-step explanation:
Scarlett bought an ant farm with 80 ants. From the following week forward, the ant population tripled every week.
So, the population of ant after 1st week will be (80 × 3) = 240
Again, after 2 weeks this will be (240 × 3) = 720
Therefore, the ant population is increasing in a geometric sequence and here the first term is 80 and the common ratio is 3.
Hence, if a(n) is the population of ant after n weeks then,
(Answer)
Now, there will be
ants after 8 weeks. (Answer)
Answer:
The parameter is the population proportion of fans who listened to her new single and has an estimated value of 90%.
Step-by-step explanation:
The parameter is a value that corresponds to a population, while an a value that corresponds to a sample is know as statistic.
She takes a sample to estimate, with a point estimate and probably with a confidence interval around this point estimate, the true proportion of fans who listened to her new single.
This is the paramater: the population proportion of fans who listened to her new single.
Its value comes from an estimation based on the sample proportion (point estimate).
The sample proportion is 90%, so we can estimate, as there is no bias, that the population proportion is also 90%.

Answer:
38°
Step-by-step explanation:
All triangles have a sum of 180°
180 - (119 + 23) = missing angle
180 - (142) = missing angle
38 = missing angle
So, the missing angle has a measurement of 38°
