Determine whether

is equivalent to each of the following expressions.
Equivalent
Not equivalent
25m-1
252m-1
52m-1
Answer:
(a) and (b) are not equivalent
(c) is equivalent
Step-by-step explanation:
Given
[tex]\frac{25^m}{5}[/tex]
Required
Determine an equivalent or nonequivalent expression
[tex](a)\ 25^{m-1[/tex]
We have:
[tex]25^{m-1[/tex]
Apply law of indices
[tex]25^{m-1} = \frac{25^m}{25}[/tex]
This is not equivalent to [tex]\frac{25^m}{5}[/tex]
[tex](b)\ 25^{2m - 1}[/tex]
We have:
[tex]25^{2m - 1}[/tex]
Apply law of indices
[tex]25^{2m - 1} = \frac{25^{2m}}{25}[/tex]
This is not equivalent to [tex]\frac{25^m}{5}[/tex]
[tex](c)\ 5^{2m-1}[/tex]
We have:
[tex]5^{2m-1}[/tex]
Apply law of indices
[tex]5^{2m-1} = \frac{5^{2m}}{5^1}[/tex]
[tex]5^{2m-1} = \frac{5^{2m}}{5}[/tex]
Evaluate the numerator
[tex]5^{2m-1} = \frac{25m}{5}[/tex]
This is an equivalent expression

This question is incomplete, the complete question is;
An article in Knee Surgery, Sports Traumatology, Arthroscopy (2005, Vol. 13, pp. 273-279), considered arthroscopic meniscal repair with an absorbable screw. Results showed that for tears greater than 25 millimeters, 13 of 19 repairs were successful while for shorter tears, 22 of 30 repairs were successful.
a) Is there evidence that the success rate is greater for longer tears? Use alpha=0.05
Answer:
P-value = 0.6443
Now, since the p-value( 0.6443 ) is greater than the significance level (0.05), We fail to reject null hypothesis.
Therefore, there is no significant difference in the successive proportion ( rate ). [tex]p[/tex]₁ = [tex]p[/tex]₂
Step-by-step explanation:
Given the data in the question;
Sample of tears greater than 25;
number of successive repairs X₁ = 13
number of repair n₁ = 19
proportion of successive repairs [tex]p[/tex]₁ = 13/19 = 0.68
q₁ = 1 - [tex]p[/tex]₁ = 1 - 0.68 = 0.32
Sample of tears shorter than 25;
number of successive repairs X₂ = 22
number of repair n₂ = 30
proportion of successive repairs [tex]p[/tex]₂ = 22/30 = 0.73
q₂ = 1 - [tex]p[/tex]₂ = 1 - 0.73 = 0.27
so;
H₀ : There is no significant difference in the successive proportions; [tex]p[/tex]₁ = [tex]p[/tex]₂
Hₐ : The successive rate is greater for longer tears [tex]p[/tex]₁ >
Significance level ∝ = 0.05
Test Statistics
Z = ([tex]p[/tex]₁ -
so we substitute
Z = ( 0.68 - 0.73 / √[ (0.68 ×0.32 / 19) + ( 0.73×0.27 / 30 ) ]
Z = -0.05 / √[ 0.01802 ]
Z = -0.05 / 0.1342
Z = -0.37
P-value for the given test, p = P( Z > -0.37 )
= 1 - P( Z ≤ - 0.37 )
= 1 - 0.35569
P-value = 0.6443
Now, since the p-value( 0.6443 ) is greater than the significance level (0.05), We fail to reject null hypothesis.
Therefore, there is no significant difference in the successive proportion ( rate ). [tex]p[/tex]₁ = [tex]p[/tex]₂

Answer:
The Value of x = 23.1 unit
Step-by-step explanation:
Given:
Parallel line intersect
Find:
The value of "X"
Computation:
We know that given lines are parallels
So, by using Ratio theorem we can find the value of "x"
Ratio theorem of parallel lines say
AB / BC = AD / DE
So,
14 / 20 = x / 33
x = [14 x 33] / 20
The Value of x = 23.1 unit
Find the measurement indicated in each parallelogram.
1)
с
40°
D
E
Answer:
D=40
C=140
E=140
Step-by-step explanation:
opposite angles are congruent in parallelograms, so D is equal to 40. Also, the interior angles of any quadrilateral always equal 360, and because there are only 2 angles left that we don't know what they equal, if we add 40 to 40, which equals 80, and then subtract 80 from 360, we get 280, which we then divide by 2, to get 140 for C and E.

Find the volume of Figure B.
Help please!!
The volume of figure B that is similar to figure A is: 44 cu. ft.
How to Find the Volume of Similar Figures?If the volumes of two figures are A and B respectively, and their radius is a and b respectively, then, Volume of A/volume of B = a³/b³.
Given that figures A and B are similar, we would have the following ratio:
352/volume of B = 4³/2³
352/volume of B = 64/8
352/volume of B = 8
Volume of B = 352/8
Volume of B = 44 cu. ft.

4n -6 = 10n
Simplify.
-----------------------------------------------------------------------------------------------------------------
Answer: n = -1
-----------------------------------------------------------------------------------------------------------------
add 6 to both sides of the equation.
4n − 6 = 10n
4n − 6 + 6 = 10n + 6
-----------------------------------------------------------------------------------------------------------------
simplify.
(add the numbers)
4n − 6 + 6 = 10n + 6
4n = 10n + 6
4n = 10n + 6
-----------------------------------------------------------------------------------------------------------------
subtract 10n from both sides.
4n − 10n = 10n + 6 − 10n
-----------------------------------------------------------------------------------------------------------------
simplify. (again)
(combine like terms) (combine like terms)
4n − 10n = 10n + 6 − 10n −6n = 10n + 6 − 10n
−6n = 6
-----------------------------------------------------------------------------------------------------------------
divide both sides by the same term.
−6n/−6 = 6/-6
n = 6/−6n = 6/−6
-----------------------------------------------------------------------------------------------------------------
simplify. (again)
(cancel terms that are in both the numerator and denominator)
n = 6/−6
(divide the numbers)
n = 6/−6
n = 1
