Answer and explanation:
They are not equivalent because if we simplify the second expression, the result isn't the same:
7(y×b)+3b
= 7(yb)+3b
=7yb + 3b
Therefore 7yb+3b≠7y+7b+3y
And even though you meant
7(y+b)+3b
=7y+7b+3b
=7y+10b
7y+10b≠10y+7b
Answer:
I'd say your answer should be (B.) A and B
Step-by-step explanation:
point B on your graph is in quadrant one.
also, your point is at (5,4) so both numbers of your point are positive.
therefore, your answer should be (B.) A and B
Hope this helps!
Answer:
Step-by-step explanation:
Since the scores of the math test are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = math test scores.
µ = mean score
σ = standard deviation
From the information given,
µ = 76
σ = 5
The probability that a student scored below 65 is expressed as
P(x < 65)
For x = 65
z = (65 - 76)/5 = - 2.2
Looking at the normal distribution table, the probability corresponding to the z score is 0.014
The percentage of students that scored below 65 is
0.014 × 100 = 1.4%
