Answer:
9 days.
Step-by-step explanation:
We first subtract the amount already done from the total needed.
<em>10 - 1 = 9.</em>
Next, we take the remainder and divide it by the amount being made per day to get our final answer.
<em>9 / 1 = </em><em>9</em>.
The answer is 9 days.
Answer:
33% or with 10th place decimal 33.3%
Step-by-step explanation:
1/3 has a continuous decimal form of .333333...
So, it is usually rounded to .33
Hope this helps!
Answer:we know that
area of triangle=b*h/2
b=(x-2) m
Area=(x²-4) m²
h=?
(x²-4)=(x+2)*h/2
but remember that
(x²-4)=(x+2)*(x-2)
so
subsititute
(x+2)*(x-2)=(x+2)*h/2
(x-2)=h/2
h=2*(x-2)
the answer is
the height of a triangle is 2*(x-2)
Step-by-step explanation:

I think it’s increasing i’m not sure though
In this case, we can use the z statistic to find for the proportion
of students who failed the exam. The formula for z score is given as:
t = (x – u) / s
where,
x = the sample score = 60
u = sample score mean = 82
s = standard deviation = 11
Substituting all given values into the equation:
t = (60 – 82) / 11
t = - 2
Based from the standard proportion distribution tables for
z, this corresponds to:
P = 0.0228
This means that 2.28% of the students failed the exam or
equivalent to:
failed students = (0.0228) * 85 = 1.938
<span>approximately 2 students failed the exam</span>
