Answer:
sqrt239
Step-by-step explanation:
Using the pythagoream thereom, we know that a^2+b^2=c^2.
so x^2+17=256
That makes x the square root of 239.
The First Answer Should Be 2 Not Four
The Second Answer:
12 : x
4 : 21
Cross Multiply
4x = 252
x = 63
Answer:
920 points.
Step-by-step explanation:
We have been given that the mean score for a standardized test is 800 and the standard deviation is 120. To qualify for a special summer camp for accelerated students, a student must score within the top 16% of all scores on the test.
First of all we will find probability of 0.16 using normal distribution table.
Using normal distribution our Z score will be 0.994458
Now we will use raw-score formula to find the score (x) that a student must make to qualify for summer camp.

Upon substituting our given values in above formula we will get,


Upon rounding to nearest whole number we will get,

Therefore, a student must make 920 points to qualify for summer camp.
No, a function has one input and one output
The given equation -4y + 4y + 2 = 2 have infinite solutions.
According to the given question.
We have a equation.
-4y + 4y + 2 = 2
Solve the above equation for finding the number of solutions.
-4y + 4y + 2 - 2 = 2- 2
⇒ 0 = 0
The coefficients and the constants match after combining the like terms. This gives us a true statement.
We can see that in the final equation, both sides are equal. Therefore, it has an infinite solution.
Hence, the given equation -4y + 4y + 2 = 2 have infinite solutions.
