Answer:
Common Ratio = 2
Step-by-step explanation:
Emily started with 12 lb at start.
She will double each day
So,
2nd day she will take up weight = 12 * 2 = 24
3rd day she will take up weight = 24 * 2 = 48
and so on
This is a geometric sequence, which is a sequence where each term is found by multiplying the previous term by a constant which is known as the common ratio.
Here, we are multiplying by "2" to get the next term, so we an say the common ratio is "2".
<u>Answer: Common Ratio = 2</u>
Answer: 3/20
Step-by-step explanation:
12/80 is simplified to 3/20
If your friends is 160 cm then he 1.6m
1m is 100 cm
So 1.6m is 160 cm
Answer:
X = 4
Y = 3
Step-by-step explanation:
Answer:
The probability is 0.080757
Step-by-step explanation:
We start by calculating the z-score
z-score = (x-mean)/SD/ √n
In this case;
x = 247 , mean = 240, SD = 50 and n = 100
z-score = (247-240)/50/√100
z-score = 7/50/10
= 7/5 = 1.4
So the probability we want to calculate is;
P( x > 1.4)
we can use the standard normal distribution table for this
P(x > 1.4) = 0.080757
