Step-by-step explanation:
Decide on the number of classes.
Determine the range, i.e., the difference between the highest and lowest observations in the data.
Divide range by the number of classes to estimate approximate size of the interval

Answer:
A,C, & D
Step-by-step explanation:
Answer:
x ∈ {2, 3, 4, 5, 6, 7}
Step-by-step explanation:
The equation you have written only has two real solutions. Perhaps you intend ...
The base quadratic equation factors as ...
(x -5)(x -2) +1
so will have the value 1 for x=2 and x=5. The exponent quadratic can have any value and the intended equation will be satisfied.
__
The exponent quadratic factors as ...
(x -6)(x -7)
so will be zero for x=6 and x=7. The base quadratic can have any non-zero value and the intended equation will be satisfied.
So, the four solutions found by a typical solver or graphing program are ...
x ∈ {2, 5, 6, 7}
___
In general, for values of x between 2.382 and 4.618, the base quadratic will be negative and the left side of the equation will be complex. However, there are 10 values of x where the imaginary part is zero, and two of these where the real part is 1. These values of x are x=3 and x=4, where the equation is (-1)^6 = 1 and (-1)^12=1.
In summary, the solutions are ...
x ∈ {2, 3, 4, 5, 6, 7}
Step-by-step explanation:
Hello there, I think your question missed key information, allow me to add in and hope it will fit the orginal one.
Let assume the side of the cube is a units
=>The surface area of the cude is:
- A =
Given that The bottom of the cake and the area where the two cakes meet is not frosted.
=> the are of a cube that is frosted in the first layer
A' = A -
= -
=5
=> the are of a cube that is frosted in the second layer
A'' = - - (the bottom and the top of it are not frosted)
= 4
=> the total the area of the cake that is frosted is:
TA = A' + A''
= 5 + 4
= 9 square units
To solve this type of question, you just need to substitute the actual side of the cube into the expression 9 . Hope it will find you well.
Answer:
3(a-2)
Explanation:
It is equivalent because it uses the same numbers, giving it the same solution.
(However, a could not be outside the parentheses and it still be equivalent.
