Answer:
The quotient is x² + 6x +3
Remainder = -1
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given Polynomial equation
f(x) = x³+5x²−9x−7
By using synthetic division
<em> x = 2 </em> 1 5 -9 -7
<u> 0 1 12 6</u>
<u> 1 6 3 </u><em><u> -1 </u></em><u> </u>
The quotient is x² + 6x +3
Remainder = -1
Answer: 135 days
Step-by-step explanation:
Since the amount of time it takes her to arrive is normally distributed, then according to the central limit theorem,
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = standard deviation
From the information given,
µ = 21 minutes
σ = 3.5 minutes
the probability that her commute would be between 19 and 26 minutes is expressed as
P(19 ≤ x ≤ 26)
For (19 ≤ x),
z = (19 - 21)/3.5 = - 0.57
Looking at the normal distribution table, the probability corresponding to the z score is 0.28
For (x ≤ 26),
z = (26 - 21)/3.5 = 1.43
Looking at the normal distribution table, the probability corresponding to the z score is 0.92
Therefore,
P(19 ≤ x ≤ 26) = 0.92 - 28 = 0.64
The number of times that her commute would be between 19 and 26 minutes is
0.64 × 211 = 135 days
Try and get the variable by its self by -81 from both sides then divide it by 7 and get ur answer.
Answer:
It's 16 units. Just look at the lengths and how many times they are on a shape. The shape is a rectangle, which means there will be two of each length, so just add them all together. 6+6+2+2=16
Answer:
12/4
Step-by-step explanation:
4/4 is 1
1/4 is well 1/4
2 2/4 is 2 1/2
12/4 is 3
the greatest fraction is 3
