Using Laws of exponents, the solution to the expression √(3p⁹q⁷r⁶)/(16x⁶y¹²) is; (p⁴q³r³/(x³y⁶))√(3pq/16)
How to use laws of exponents?The different laws of exponents are;
1) Product With the Same Bases; a^m × a^n = a^(m+n)
where;
m and n are real numbers.
2) Quotient with Same Bases;
a^m/a^n = a^(m-n)
where;
a is a non-zero term and m and n are integers.
3) Power Raised to a Power; (a^m)^n = a^(mn)
where;
a is a non-zero term and m and n are integers.
4) Product to a Power; a^n * b^n = (ab)^(n)
where;
a is a non-zero term and n is the integer.
5) Quotient to a Power; It states that the fraction of two different bases with the same power is represented as; a^n/b^n = (a/b)^n
where;
a and b are non-zero terms and n is an integer.
6) Zero Power; When the power of any integer is zero, then it means that its' value is equal to 1, such that;
a⁰ = 1
where;
a is any non-zero term.
7) Negative Exponent Rule; a^(-m) = 1/(a^m)
We are given the expression as;
√(3p⁹q⁷r⁶)/(16x⁶y¹²)
Applying the laws of exponents, we will have;
√(3p⁹q⁷r⁶)/(16x⁶y¹²) = (p⁴q³r³/(x³y⁶))√(3pq/16)

A cellphone provider has the business objective of wanting to determine the proportion of subscribers who would upgrade to a new cellphone with improved features if it were made available at a substantially reduced cost. Data are collected from a random sample of 500 subscribers. The results indicate that 110 of the subscribers would upgrade to a new cellphone at a reduced cost. Reducing the price will be profitable if at least 20% of the subscribers would upgrade. Complete parts (a) and (b) below
b. What is the test statistic?
The test statistic, using the z-distribution, is given as follows:
z = 1.12.
What are the hypothesis tested?At the null hypothesis, it is tested if there is not enough evidence that the proportion is greater than 20%, that is:
[tex]H_0: p \leq 0.2[/tex]
At the alternative hypothesis, it is tested if there is evidence that the proportion is greater than 20%, that is:
[tex]H_0: p > 0.2[/tex]
What is the test statistic?The test statistic is given by the equation presented as follows:

Suppose that white wool (W) is dominant over brown wool (w) in sheep. If two heterozygous sheep are crossed, what is the probability that their babies would have brown wool?
A:50%
B:75%
C:100%
D:25%
The probability that their babies would have brown wool will be 25%.
What is heterozygous?When two or more alleles for the same characters are present at the same loci on homologous chromosomes, a cell, a nucleus, or a single organism is said to be heterozygous. In contrast to homozygous, where the alleles are identical, it signifies that the alleles that code for the same gene or characteristic are different.
Given, the two-parent sheep would need to have heterozygosity for their genotype if we were to assume straightforward Mendelian genetics. Black would not be dominant in this situation; instead, the parents would be, shall we say, Rr for color. Imagine that each parent can only contribute one allele (either the R or the r). If both should chance to deliver the r, the child would be black.
Therefore, 25% of the following generation's children are likely to be black. There would be a 25% probability of a homozygous dominant offspring, a 50% chance of a heterozygous offspring, and a 25% chance of a homozygous recessive offspring if you filled out a Punnett square for this issue. Since white is the dominant allele in this situation, both the homozygous dominant allele, which accounts for 75% of the possibilities and the heterozygous child will be white. Since two recessive alleles are required to manifest the recessive phenotype, the remaining 25% of people are black.

Let the number of small boxes is s and number of large boxes is l.
s and l are our variables.
Total number of boxes is 21:
s + l = 21This is your first equation.
The volume of a small box is a (since it is not given, if you have it please replace it with that number), and the volume of all small boxes is as.
The volume of a larger box is 14 cubic feet, and the volume of all large boxes is 14l cubic feet.

Step-by-step explanation:
the sum of angles in a triangel is 180°
so for 9:
180 = 78 + 31 + x
180 - 78 - 31 = x = 71
it's a sharp triangel because all angles are smaller than 90°
you can calculate the angles of 10 and 11 the same way
which gives 10: 110°
this is a stump triangel because there s an angle greater than 90°

It will take approximately 54 years for the element to decay from 18 grams to 2 grams at a rate of 4% per year.
What is an exponential function?An exponential function is defined as a function whose value is a constant raised to the power of an argument is called an exponential function.
To determine how long it takes for an element to decay from 18 grams to 2 grams, you can use the formula:
t = (ln(A/B)) / (-r)
where:
t is the time it takes for the decay to occur
A is the initial amount of the element, in this case 18 grams
B is the final amount of the element, in this case 2 grams
r is the decay rate, in this case 4% per year
Plugging these values into the formula gives you:
t = (ln(18/2)) / (-0.04)
t = (ln(9)) / (-0.04)
t = (2.1972) / (-0.04)
t = -54.30
Hence, It will take approximately 54 years.

The value at which acceleration is zero is t = 5/3
How to determine the value of t at which acceleration is zero?Acceleration is defined as the rate at which velocity changes with time, in terms of both speed and direction
Given: the equation of motion, velocity, s = t⁶ - 2t⁵
Since acceleration is the rate at which velocity changes with time. You need to differentiate the velocity with respect to time. Thus:
ds/dt = 6t⁵ - 10t⁴ (Note: ds/dt is the acceleration)
Also, acceleration is equal to zero. That is:
6t⁵ - 10t⁴ = 0
6t⁵ = 10t⁴
6t = 10
t = 10/6 = 5/3

An event's probability is a number between 0 and 1. In this case, 0 denotes the impossibility of the event and 1 represents certainty.
