Answer:
The minimum score that an applicant must make on the test to be accepted is 360.
Step-by-step explanation:
Given : A highly selective boarding school will only admit students who place at least 2.5 standard deviations above the mean on a standardized test that has a mean of 300 and a standard deviation of 24.
To find : What is the minimum score that an applicant must make on the test to be accepted?
Solution :
We apply the z formula,
Where, z value= 2.5
is the mean of the population
is the standard deviation
x is the sample mean.
Substituting the values in the formula,
Therefore, The minimum score that an applicant must make on the test to be accepted is 360.
Scientific notation that's involved with numbers less than one, should always be counted from left to right. Count starting from the decimal until the first number you "jump over". What are you counting exactly?- the number of digits between the decimal and the first 'number' other than zero.
0.0000321 can be also written as 3.21*10^-5 (or 10 with a negative 5 exponent)
Hope this helps.
Answer:
First you need to find what x is equal to.
Step-by-step explanation:
Since 3x-5 is what you need to find divide 3 by 3x to get x alone and do the same for -5/ 3 which -1.6666667, and you can estimate it to be -1.67 so x is about -1.67.
In -3,-1,0,3 is -3 and 3 pair of numbers has a sum of 0.
To find the possible pair of integers in each section, we apply the notion of integers. If it's possible, choose any two variables from a set of numbers and look for relationships between them.
Positive and negative counting numbers, as well as zero, make up integers. Think about each pair of integers or numbers whose sum will be zero. Discover this particular pair. There are numerous ways to obtain two integers whose total is zero. However, the number must match the opposing sign exactly.
Given numbers are -3,-1,0,3
From the given sum of the numbers, -3 and 3 are zero.
-3+3=0
