Write an equation for the following points. (1, 100) (2, 50) (4, 25), (5, 20)
The equation of line is y = -50x + 150
What is Slope?
A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
Points:(1, 100) (2, 50) (4, 25), (5, 20)
so, the slope is
= (50-100)/ (2-1)
= -50 /1
= -50
using slope intercept form
y - 100 = m (x- 1)
y- 100 = -50(x-1)
y- 100 = -50x + 50
y = -50x + 50 + 100
y = -50x + 150
Hence, the equation of line is y = -50x + 150.

Show her free-throw results as a fraction. Explain why a fraction is a
useful way to show these statistics.
She made 12 out of 25 free throws, so in fraction it is expressed as 12/25. A fraction is useful here to show how many of her throws are successful compared to all the attempted throws.
A fraction is defined to be a part of a whole. It can also be defined as a numerical quantity that's not an integer. The parts of a whole or collection of things can be represented by a fraction. For instance, to cut a pie in half means we cut the pie so that there will be 2 halves of the pie.
A common fraction has two parts, which are the numerator and the denominator. The number above the line is the numerator, while the number under the line is the denominator. The numerator represents the parts and the denominator represents a whole collection.

log3 5 + log3 x = log3 35
Answer:
X=7
Step-by-step explanation:
To solve this equation, we need to use the logarithmic properties. First, we can use the property loga(bx) = x loga(b) to rewrite the equation:
log3(5) + log3(x) = log3(35)
This can be rewritten as:
log3(5x) = log3(35)
Using the property loga(b) = c, we can re-write the equation as:
x = 35/5
Now, we can calculate the value of 35/5:
35/5 = 7
Therefore, the solution to the equation is x = 7.
Pat and Rich drove to the beach
last weekend. It took them twice as
long to get back as it did to drive
there. If they spent 9 hours traveling
to and from the beach, how long
did it take them to drive each way?
The total time that it took Pat and Rich to get to the beach is given as 3 hours.
How to solve for the total timeLet's call the time it took Pat and Rich to drive to the beach "t".
Since it took them twice as long to get back, it took them 2t to get back.
The total time they spent traveling was 9 hours, so we can set up an equation:
t + 2t = 9
Combining like terms:
3t = 9
Finally, dividing both sides by 3:
t = 3
So it took them 3 hours to drive to the beach, and 6 hours to drive back.

The average lifetime of smoke detectors that a company manufactures is 5 years, or 60 months, and the standard deviation is 8 months. Find the probability that
sample of 29 smoke detectors will have a mean lifetime
between 57 and 64 months. Assume that the sample is taken from a large population and the correction factor can be ignored.
Round the final answer to at least four decimal places and intermediate z-value calculations to two decimal places.
The required probability is 0.8945 that a sample of 29 smoke detectors will have a mean lifetime between 57 and 64 months.
To find the probability that a sample mean is between 57 and 64 months, we need to find the standard deviation of the sample mean, which is given by the standard deviation of the population divided by the square root of the sample size.
The standard deviation of the sample mean = standard deviation of the population / square root of sample size = 8 / √(29) = 8 / 5.385 = 1.48
Next, we need to standardize the interval of 57-64 months by subtracting the mean and dividing it by the standard deviation of the sample mean.
z₁ = (57 - 60) / 1.48 = -2.03
z₂ = (64 - 60) / 1.48 = 1.35
Finally, we can use a standard normal table to find the area under the normal curve between z₁ and z₂, which gives us the probability of a sample mean falling in the interval (57, 64).
P(57 < X < 64) = P(-2.03 < Z < 1.35) = 0.9790 - 0.0845 = 0.8945
Therefore, the final answer is 0.8945, rounded to four decimal places.

The trigonometric function equation obtained for the graph is y = 4 sec (πx) - 2.
What is trigonometric function?
Simply put, trigonometric functions also referred to as circular functions are the functions of a triangle's angle. This means that these trig functions provide the relationship between the angles and sides of a triangle.
The upper waver have a value of y = 2 and the lower waves have a value of y = -6.
Add the points and divide by 2 -
[2 + (-6)] / 2
(2 - 6) / 2
-4 / 2
-2
Therefore, the midline is y = -2.
The vertical asymptotes are drawn and they intersect the midline at certain points.
Then the sinusoidal function is drawn using the intersection point.
There is one period of sinusoidal function that is starting from x = 0 and goes upto x = 2.
This pattern tells that the function is of cosine.
Then the graph will be of trigonometric function secant .
The value of C = -2 , A = 4, D = 0
Here C is the midline value, A is the points above and below the midline, D is the horizontal shift and 2π/B is the period.
Now, 2π/B = 2
2B = 2π
B = π
Now, use the formula -
y = A cos (B(x - D)) + C
y = 4 cos (π(x - 0)) - 2
y = 4 cos (πx) - 2
y = 4 sec (πx) - 2
Now plot the graph for the obtained function.
The graph is same as given in the question.

Two plants that are pure bred are crossed. One is short and one is tall, Tall is dominant. What are the expected phenotypes for the offspring?
A. All tall
B. All short
C. Half short, half tall
D. All medium height
The expected phenotypes for the offspring is All tall.
What is Phenotype?Mendel came to the conclusion that some features predominated over other inherited traits when he noticed that a heterozygote offspring might exhibit the same phenotype as the parent homozygote. However, the connection between genotype and phenotype is rarely as straightforward as Mendel's descriptions of dominant and recessive patterns.
Given:
One is short and one is tall, Tall is dominant.
When two plants that are tall and short are crossed. They would all produce tall plants as a result, T.
The first crossing produced these children.
As a result of their parents' TT and SS genes, they all now have TS genes.
There will be some towering and some short off springs when these off springs are crossed. TS and TS will cross at this location. Given that they are all genetically tall and short.
So, The ratio of tall to short children they would have according to Mendel is 3:1.

13 is a factor that is more than 4 and less then 26
The factor of the number 26 that is between 4 and 26 is 13. Factors are the numbers that can divide into a number without leaving a remainder. In this case, the factors of 26 are 1, 2, 13, and 26.
Explanation:In mathematics, a factor of a number is a number that divides into another number without leaving a remainder. In the case of the number 26, its factors include 1, 2, 13, and 26. The factor of 26 that is between 4 and 26 is 13.
To find this, you can go through the factors of 26 one by one. The factors are found by dividing 26 by all the numbers up to 26, and the numbers that give a remainder of 0 are the factors.

Answer:
D
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{1}{2}[/tex] x + 3 ← is in slope- intercept form
with slope m = [tex]\frac{1}{2}[/tex]
• Parallel lines have equal slopes , then
y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation
to find c substitute (2, - 4 ) into the partial equation
- 4 = [tex]\frac{1}{2}[/tex] (2) + c = 1 + c ( subtract 1 from both sides )
- 5 = c
y = [tex]\frac{1}{2}[/tex] x - 5 ← equation of parallel line
