So go down and up then look it up on the web so you can look good in it that really helps
C - no solution
you take the second solution and times the entire equation by -1
then simply
and you get 0x + 0y = 20
Answer:
B, coefficient vertically stretches or compress not horizontally, plus it is negative so x axis dlip
17-2(6-4)(7-3)-7
17-2(2)(4)-7
17-2(8)-7
17-16-7
1-7
-6
Answer:
Step-by-step explanation:
Since the results for the standardized test are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = test reults
µ = mean score
σ = standard deviation
From the information given,
µ = 1700 points
σ = 75 points
We want to the probability that a student will score more than 1700 points. This is expressed as
P(x > 1700) = 1 - P(x ≤ 1700)
For x = 1700,
z = (1700 - 1700)/75 = 0/75 = 0
Looking at the normal distribution table, the probability corresponding to the z score is 0.5
P(x > 1700) = 1 - 0.5 = 0.5
