Answer:
y = -5/2x + 1
Step-by-step explanation:
y=mx+b
m is slope
b is y intercept
x(2x²+4x-1) is your answer.Hope this helps. :)
Answer:
a. 2.5%
Step-by-step explanation:
The Z-score of the given test score is ...
Z = (X -μ)/σ = (700 -500)/100 = 2
The empirical rule tells you 95% of a normal distribution is within 2σ of the mean. The other 5% is split evenly between the two tails of the distribution, so the probability of a score 2σ or more above the mean is about 1/2×5% = 2.5%.
Question is not Proper.The Proper Question is given below.
∠P and ∠Q are complementary. m∠P = 52° and m∠Q = (3x + 2)°. Find the value of x. Show your work.
Answer:
Therefore the value of x is
Step-by-step explanation:
Given:
∠P and ∠Q are complementary.
m∠P = 52° and
m∠Q = (3x + 2)°.
To Find:
x = ?
Solution:
Complementary Angles:
Two angles are Complementary when they add up to 90 degrees.
Example 40° and 50° are Complementary Angles.
If 'x' and 'y' are Complementary Angles the we have
Here, ∠P and ∠Q are complementary.
Substituting the values we get
Therefore the value of x is
