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:
The new area will be 1/4 of the old area.
Step-by-step explanation:
If you don't know the answer already from (1/2)^2 = 1/4, you can figure it out.
new area = (1/2·5 mm)·(1/2·5 mm) = (1/2)^2·(5 mm)^2
old area = (5 mm)·(5 mm) = (5 mm)^2
Then the ratio of new area to old area is ...
((1/2)^2·(5 mm)^2)/(5 mm)^2 = (1/2)^2 = 1/4
___
When any plane figure has its linear dimensions scaled by a factor of "s", its area will be scaled by a factor of s^2.
Here, s=1/2, and s^2 = 1/4, the ratio of new area to old.
Hi there!
To solve this problem, we need to divide 324 by 24:
324 / 24 = 13.5
Since you can't make half of a group, the answer is 13 groups.
Hope this helps!
Answer:
i would say 7.62.
Step-by-step explanation:
i would chose that because the best way for finding the answer is to count the spaces from point a to point b.
