Answer: his score 131 points
Step-by-step explanation:
Assuming the scores in the standardized test are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = standardized test scores.
µ = mean score
σ = standard deviation
From the information given,
µ = 110 points
σ = 10 points
Looking at the normal distribution table, the z score that corresponds to the 98 percentile is 2.06
2.06 = (x - 110)/10
Cross multiplying, it becomes
2.06 × 10 = x - 110
2.06 = x - 110
x = 20.6 + 110
x = 130.6
Approximately, x = 131
Answer:
x = 2
Step-by-step explanation:
Used a scientific calculator.
Answer:i think it is y-y1=m(x-x1)
m is herein undefined.
Slope, m, is defined as change-of-y divided by change-of-x...
m=(y-y1)/(x-x1)
The mathematical concept of undefined means that the denominator is zero. This means that both values of x are equal.
(-4,-8)
This equation is x=-4
It is a vertical line and includes the point of y=-8.

Answer:
9331
Step-by-step explanation:
clearly, r=6
So, if there are n+1 terms, 6^n = 7776
n = 5
S6 = a(r^6-1)/(r-1) = 1(6^6-1)/(6-1) = 46655/5
You multiply them so it would be 0.08
