Answer:
A) 283.4mm^2
Step-by-step explanation:
Ok area of a circle
A=πr2
Radius is half of diameter
19/2=9.5
so
A=(3.14)9.5^2
A=283.385
round this nearest tenth
283.4mm^2
It has been given that the Fibonacci sequence starts as 0, 1 , 1 , 2 , 3 , 5 , 8
We can see that every term is equal to the sum of the previous two terms
We already have 7 terms, so to determine the next three terms:
term 8 = t₈ = t₇ + t₆ = 8 + 5 = 13
term 9 = t₉ = t₈ + t₇ = 13 + 8 = 21
term 9 = t₁₀ = t₉ + t₈ = 21 + 13 = 34
Hence, the next three terms are 13, 21 and 34. So the correct option is B

Step-by-step explanation:
Z-score may be defined as a position of the raw score in regard to the distance from its mean when it is measured in the units of standard deviation. Z-score is considered as positive, when the values is above the mean. And when it is below the mean, it is considered as negative.
Another name of a z-score is standard score. Z-score can be measured using the relation :

where, z = z-score
x = raw score
μ = population mean
σ = population standard deviation
Thus from the formula we can see how many standard deviation the score is from a men of the distribution by looking at the corresponding z-score.
