The equation used is option b , y = 1/2x² and y = 64
Isosceles triangle: What is it?
A triangle with two sides that have the same length is said to be isosceles.
Given,
Area of triangle = 64 sq.ft
Here, an isosceles triangle has two equal sides
Let
x is equal to the length side of a right isosceles triangle's leg.
y is the area of a right isosceles triangle at position
Currently, the legs of a right isosceles triangle are equal.
Area of triangle = 1/2 × base × height
y = 1/2 × (x) × (x)
y = x²/2
64 = x²/2
128 = x²
x = √128
x = 8√2
The length of the legs of the sun shade is 8√2 feet.

A researcher is testing the effect of a new cold and flu medication on reaction time. A sample of n=16 students is obtained and each student is given the normal dose of the medicine. Thirty minutes later, each student’s reaction time is measured. The scores for the sample averaged 220 milliseconds with a standard deviation of 20. Assuming that reaction time for students in the regular population averages 200 milliseconds, are the data sufficient to conclude that the medication has a significant effect on reaction time? Use a two-tailed single-sample (one-group) t-test with alpha = .05.
What are the null and alternative hypotheses?
The null hypothesis is that the reaction time for students in the regular population averages 200 milliseconds.
The alternate hypothesis is that the reaction time for students in not the regular population averages 200 milliseconds.
What is null hypothesis?In statistical hypothesis testing, null and alternate hypotheses are utilized. The alternative hypothesis of a test expresses your research's prediction of an effect or relationship, whereas the null hypothesis of a test always predicts no effect or no association between variables.
With the aid of a statistical test, researchers weigh the evidence in favor of and against the null and alternative hypotheses, which are two opposing claims:

find the distance between the parallel lines. if necessary, round your answer to the nearest tenth. coordinate plane shows two lines. line y equals negative 3 x plus 1 and line y equals negative 3 x plus 4.
By taking the difference between the y-intercepts, we conclude that the distance between the lines is 3 units.
How to find the distance between the parallel lines?A general linear equation is:
y = a*x + b
Where a is the slope and b is the y-intercept.
Two linear equations are parallel if and only if both lines have the same slope and different y-intercepts.
And the distance is given by the difference between the y-intercepts.
Here the lines are:
y = -3*x + 1
y = -3*x + 4
The difference between the y-intercepts gives:
4 - 1 = 3

In a company's first year in operation, it made an annual profit of $111, 000. The
profit of the company increased at a constant 24% per year each year. How much
total profit would the company make over the course of its first 24 years of operation,
to the nearest whole number?
The total profit made by the company over the course of its first 24 years of operation is $10,016,640
Given,
The annual profit made by a company in first year = $111,000
The increase in profit per year = 24% = $26640
We have to find the total profit made by the company over the course of its first 24 years of operation
Lets take this as an arithmetic progression.
First term, a = 111,000
Common difference, d = 26640
nth term = 24
Sum of nth term,
Sₙ = n/2 [2a + (n - 1) d]
S₂₄ = 24/2 [2 × 111,000 + (24 -1) 26640]
S₂₄ = 12 [222,000 + 23 × 26640]
S₂₄ = 12 [222,000 + 612,720]
S₂₄ = 12 × 834,720

Shanika is thinking of a rational number, but tells you its opposite. What is true about the number she is thinking of?
a- it is located at zero on the number line
b-it is to the right of zero on the number line
c- it is twice as far from zero as the number she tells you
d-it is the same distance from zero as the number she tells you
Answer:
d. It is the same distance from zero as the number she tells you.
Step-by-step explanation:
Case 1: Let Shanika thought a positive rational
number
Let the number that Shanika thought be c.
Then, the distance of it from zero = lc - Ol = c.
But, the number she told = -c
The distance of -c from zero = 10--(-c)| = c
Case 2: Let Shanika thought a negative rational number
Let the number that Shanika thought be -c (c>0).
Then, the distance of it from zero = 10--(-c)| = c.
But, the number she told = c
The distance of -c from zero = Ic-01 = c
In both cases, the number she thought is the same distance from zero as the number she tells us.

The equation of the linear function represented in the table in slope intercept form is y = 7x -2
How to represent linear equation in slope intercept form?A linear function can be represented in slope intercept form as follows:
y = mx + b
where
m = slopeb = y-interceptTherefore, the table follows a linear pattern.
Hence, using (0, -2)(1, 5) we can find the slope and the y-intercept of the linear function.
Therefore,
m = 5 - (-2) / 1 - 0
m = 5 + 2 / 1
m = 7
Therefore, let's find the y-intercept using (0, - 2).
y = mx + b

the non-engineer wants 600 pounds of total initial thrust from the 20 rockets. what is the probability that his/her scheme will produce the minimum required thrust?
The exit mass flow rate times the exit velocity less the free stream mass flow rate times the free stream velocity equals the force (thrust).
If we take into account the factors mentioned above, we will see that if the aircraft can fly at full thrust in cruise, this fits nicely with a static sea level thrust force equivalent to one third of its weight force. The thrust required to sustain flight is approximately 1/18 of the aircraft weight.

n proof testing of circuit boards, the probability that any particular diode will fail is 0.030.03. suppose a circuit board contains 150 diodes and that each one performs or fails independently of all others. how many diodes would you expect to fail, and what is the standard deviation of the number that are expected to fail? 5 points
You would expect 4.5 diodes to fail. The standard deviation of the number that are expected to fail is 2.089.
The number of diodes failing, E(X), can be calculated by multiplying the population, n, with the probability, p.
n = 150
p = 0.03
E(X) = n × p
E(X) = 150(0.03)
E(X) = 4.5
Standard deviation, denoted by σ, is defined as the measure that indicates the average distance of observations from the mean of the data set.
σ = √(n x p x (1 - p))
σ = √(150 x 0.03 x (1 - 0.03))

What is Prοbability?In mathematics, prοbability is a measure οf the likelihοοd οr chance οf an event οccurring, expressed as a number between 0 and 1, where 0 represents an impοssible event and 1 represents a certain event. It is a fundamental cοncept in statistics and is used tο mοdel and analyze a wide range οf real-wοrld phenοmena.
The prοbability οf getting a 1 οn a single die is 1/6, and the prοbability οf getting anything but a 3 οr 4 οn a single die is 4/6 (since there are 6 pοssible οutcοmes and 3 οf them result in a 3 οr a 4).
Tο find the prοbability οf getting the desired οutcοme when rοlling twο dice, we can use the multiplicatiοn rule οf prοbability, which states that the prοbability οf twο independent events οccurring tοgether is the prοduct οf their individual prοbabilities.

We get x + x = 2x by using x to signify our missing values and the assumption that there are two missing values. We obtain the equation 2x + 0.34 since it is the product of these integers and 0.34; after setting it equal to 2, 2x + 0.34 equals 2.
First, take 0.34 off both sides to get 2x = 1.66. To get x = 0.83, divide both sides by 2 now.

help meeeeeeeeeeee pleaseeeeeeeeeeeeee!!
can someone help pls????
detail for me as well
Step-by-step explanation:
the easy straight forward method is to simply sum up the 5 terms.
you know that this symbol just means "sum", right ?
and that the index variable is "running" from 1 to 5.
so, you have to sum up
3×1 + 3×2 + 3×3 + 3×4 + 3×5 = 3 + 6 + 9 + 12 + 15 = 45
now, if you want it done via a summary formula to add the first n terms of an arithmetic sequence, like in this case
a1 = 3
an = an-1 + 3 = a1×n = 3n
then
the sum of the first n terms in an arithmetic sequence is (n/2)⋅(a₁+aₙ).
it simply means : first plus last term added up n/2 times.
why ?
because a1 + an = a2 + an-1 = a3 + an-2 = ...
we get n/2 times such part sums.
so, in our case, n = 5, and we get
(3 + 3×5)×5/2 = (3 + 15)×5/2 = 18×5/2 = 9×5 = 45
Answer:
∑ (i = 1 to 5) (3·i)
= 3·∑ (i = 1 to 5) (i)
= 3·(1 + 2 + 3 + 4 + 5)
= 3·15
= 45
