1.
the closest perfect squares of 12 are 9 and 16,
that is 9<12<16
so
this means,
is 3 point something...
2.
similarly
36<40<49
so
which means
is 6 point something...
3.
<span>the sum of the integers between the square root of 12 and 40 is the sum of 4, 5 and 6, since 4 is the smallest integer after root 12, and 6 the greatest integer to before root of 40.
Answer: 15</span>
Answer:
A = 2x²-3x-5
Step-by-step explanation:
Given that,
The length of the bedroom, l = (2x-5)
Width of the bedroom, b = (x+1)
We need to find an equation for the area of the bedroom. We know that,
Area of a rectangle = lb
Put all the values,
A = (2x-5)(x+1)
= 2x²+2x-5x-5
= 2x²-3x-5
Hence, the area of the bedroom is equal to 2x²-3x-5.
Answer:
The worth of the car after 6 years is £2,134.82
Step-by-step explanation:
The amount at which Dan buys the car, PV = £2200
The rate at which the car depreciates, r = -0.5%
The car's worth, 'FV', in 6 years is given as follows;
Where;
r = The depreciation rate (negative) = -0.5%
FV = The future value of the asset
PV = The present value pf the asset = £2200
n = The number of years (depreciating) = 6
By plugging in the values, we get;
The amount the car will be worth which is its future value, FV after 6 years is FV ≈ £2,134.82 (after rounding to the nearest penny (hundredth))

Answer:
150 students
Step-by-step explanation:
According to statement we have the following information
number of juniors=n=300
mean score=24
standard deviation score=4
The number of students that score above 24 is determined by
Number of students score above 24=number of juniors* P(student score above 24)
P(student score above 24)=P(x>24)=P(x-mean/sd>24-24/4)=P(z>0)=0.5.
Students score above 24=np=300*0.5=150
Hence there are 150 students scored above 24.
