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.

You flip three coins eight times. Are you guaranteed to get three heads at least once
When one flip three coins eight times, there no guarantee to get three heads at least once as the probability is low.
What is probability?Probability is the occurence of likely events. It is the area of mathematics that deals with numerical estimates of the likelihood that an event will occur or that a statement is true.
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.
The probability of getting a head in a coin is 1/2.
Therefore, the probability of getting three heads on there flips will be:
= P(head)³
= 1/2 × 1/2 × 1/2
= 1/8
Therefore, the probability is low and the heads aren't guaranteed.

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
Therefore, the value of t at which acceleration is zero is t = 5/3

A total of 21 boxes of paper were shipped with a combined volume of 252 cubic feet. Write a system of equation that could be used to determine the number of small boxes shipped and the number of large boxes shipped. Define the variables that you can use to white the system.
Answer:
See belowStep-by-step explanation:
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.
Total volume is 252 cubic feet, add the two volumes together:
as + 14l = 252And this is your second equation (don't forget to replace a with the volume of a small box).

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 slope of the function for pronghorn antelope is 60.78 which infers that the rate of speed of the pronghorn is 60.78 miles per hour.
7) The given function that represents the speed of the pronghorn is
y = 60.78x - 5.4
Comparing this function with the general equation of a straight line
y = mx + c we can conclude that the slope of the function is 60.78 .
So the Pronghorn's rate of speed is 60.78 miles per hour.
8) Now the speed of the cheetah is given in the form of a table.
Let us take any two points on the graph
(0.5,21.85) and (2,118.60)
Slope of the line passing through these two points
= (118.6-21.85)/(2-0.5)
=64.5
So the slope of the graph is 64.5 and the average rate of speed of the Cheetah is 64.5 miles per hour.
9) From the above two slopes and the rate of speed we can conclude that the speed of the cheetah is 64.5 mph which is greater than that of the pronghorn 's speed of 60.78 miles per hour.

Collisions at the intersections are less frequent, averaging one per month at an average cost of $6,000, although none have ever caused injuries or deaths. Use this information to answer the following questions.
1. What are the annual costs from the pothole damage?
2. What are the annual costs due to damage from
collisions?
3. Given the size of the annual budget, make your

benefits per dollar spent.
1. The annual costs from the pothole damage is $156428.
2. The annual costs due to damage from
collisions is $72000 per year.
3. The project should be undertaken
How to calculate the value?1. The budget is given as $100,000
The number of cars hit potholes per week = 15
Number of cars hit potholes per year = 15*52.148
= 782.14 cars
Total amount of damage per year will be:
= 782.14 * 200 = $156428
2. Number of collusion at intersection per month = 1
Number of collusion at intersection per year = 1 * 12 = 12
Total cost of collusion at intersection per year = 12*6000
= $72000 per year
3. Saving on potholes = 156248 / 100000 = $ 1.56
Saving on collusion at intersection:
= 72000 / 100000
= $0.72
So from above, it is clear that if the budget is spent on potholes, more savings will be done. Thus the budget should be invested in potholes.
