Answer:
-5.053
Step-by-step explanation:
For complete calculation see the attachment:
mean= (0 +3+1+15+2+31+3+27+4+10+5+7+6+7)/14= 8.6429 or 9 days
standard deviation= √(∑(X-mean)²/N)
9.1309 or 9 days
1.5 standard deviation= 9.1309× 1.5= 13.6963
number 1.5 standard deviation below the mean= 8.6429-13.7= -5.053
Answer:
y=-5/3x+1
Step-by-step explanation:
The answer is y=-5/3x+1 because you would do the exact opposite of rise over run where it rises 5 units up and 3 units shifted right but instead it is still 3 units that are shifted to the right but 5 units down. We can also assume that the y-intercept is 1 based on where the slope is placed.
A) the diameter is MQ
B) radius is PR
C) chord is NO
D) I don’t understand this part of the question
Factoring in AlgebraFactors
Numbers have factors:
And expressions (like <span>x2+4x+3</span>) also have factors:
Factoring
Factoring (called "Factorising" in the UK) is the process of finding the factors:
Factoring: Finding what to multiply together to get an expression.
It is like "splitting" an expression into a multiplication of simpler expressions.
<span>Example: factor 2y+6</span>
Both 2y and 6 have a common factor of 2:
<span>2y is 2 × y6 is 2 × 3</span>
So you can factor the whole expression into:
2y+6 = 2(y+3)
So 2y+6 has been "factored into" 2 and <span>y+3</span>
