Answer:
z = 5
Step-by-step explanation:
[tex]\frac{4x^2y^7}{8x^3y^2} = \frac{y^z}{2x}[/tex]
It can be also written as -
[tex]\frac{2^2 \times x^2 \times y^7}{2^3 \times x^3 \times y^2} = \frac{1 \times x^0 \times y^z}{2 \times x^1 \times y^0}[/tex]
Using law of exponents , lets solve this.
[tex]=> 2^{(2-3)} \times x^{(2-3)} \times y^{(7 - 2)} = \frac{1}{2} \times x^{(0-1)} \times y^{(z-0)}[/tex]
[tex]=> 2^{-1} \times x^{-1} \times y^{5} = 2^{-1} \times x^{-1} \times y^z[/tex]
[tex]=> \frac{y^5}{2x} = \frac{y^z}{2x}[/tex]
[tex]=> y^z = y^5[/tex]
[tex]=> z = 5[/tex]

An artist builds a sculpture out of metal and wood that weighs 14.9 kilograms. 3/4 of this weight is metal, and the rest is wood. How much does the wood part of the sculpture weigh? (no decimals)
Answer:Weight of wood part of the sculpture (no decimals) =4kg
Step-by-step explanation:
Weight of sculpture containing metal and wood = 14.9 kg
weight of metal =3/4 x 14.9 kg =11.175kg
weight of wood =Entire sculpture − weight of metal
= 14.9 kg−11.175kg
=3.725kg
Rounding up to remove decimals we have that Weight of wood part =4kg

A biased estimator is one that deviates from the true population value. A biased sample can still be useful if the nature of the bias and how much of a bias exists is known.
An unbiased estimator is when a value from a sample is the same as the actual value of a population parameter.
The sample is not chosen at random, the inherent bias in convenience sampling means that the sample is unlikely to be representative of the population being studied. This undermines your ability to make generalizations from your sample to the population you are studying.
Therefore, the sample of the assigned reading likely to be biased and convenience sample.

Answer:
Coefficient of x = -9.9 ;
Coefficient of x = 75
Coefficient of y = 275
Step-by-step explanation:
Given :
0.8 (2x + x) + 3(7 - 4.1x) = __x + 21
0.8(3x) + 21 - 12.3x = __x + 21
2.4x + 21 - 12.3x = __x + 21
-9.9x + 21 = __x + 21

For any positive numbers a,b, and d, with b not equal to 1, log base b (a/d) = A. Log base b a * log base b d B. Log base b a + log base b d C. Log base b a - log base b d D. D * log base b a
Answer:
C. Log base b (a) - Log base b (d)
Step-by-step explanation:
In logarithm, log means index or exponent. It can be explained with following example. Consider 2^5 = 32
here index = log = 5 so you can write the log of 32 = 5
Consider 64/16 = 4
now 64 = 2^6 and 16 = 2^4
We can write log 2(64) = 6 and log2(16)=4
Now log 64/16= log 4= 2
Also log2(64)-log2(16)=6-4=2
Therefore
Log base b (a/d) = Log base b (a) - Log base b (d)
