Do you guys know how to find a square root or cube root without a calculator? I need a explanation and a example.
Answers
Answer:
square of the following
2×2=4
3×3=9
4×4=16
2×2×2=8
now
square root
√4
√2×2
=2 answer likewise other
again
cube root
√8
=√2×2×2
=2 through that you can find these
at first you should know square and cube of different numbers from 1 to 20 is the required you should know then you can easily find out answer
so take 9 for an example.
start dividing by prime numbers:
9 / 2 (can’t be done)
9/3 = 3
3/3 = 1
3 is in the answer once therefore the answer is 3

What is radicals?
A surd or radical is an unresolved root, particularly one that employs the radical symbol. A radical expression is any expression that contains a radical, whether it is a square root, a cube root, or a higher root, while an algebraic expression is any statement that does not contain any transcendental functions or transcendental numbers. The root test is used to determine the radius of convergence of a power series. The nth roots of 1 are known as roots of unity, and they play an important role in many areas of mathematics, including number theory, equation theory, and the Fourier transform.

nina made 8 withdraws each were for $20. what was the total amount of change in her bank account.
Answers
The change in Nina'a account balance is -$160.
Nina made 8 withdrawals and each time she took $20.
The change in her account balance will therefore be whatever the account balance is less the amount that she withdrew.
The total amount of money she withdrew is:
= Number of withdrawals x Amount withdrawn each time
= 20 x 8
= $160
Her account is therefore lower by $160.
In conclusion, the change in her account balance is -$160.

for a lower tail test, the test statistic z is determined to be zero. what is the p-value for this test?
Answers
0.5 is the p-value for this Z -test .
What is the Z test's p-value?
For each test, the p-value is the likelihood that the null hypothesis will be correct, which is expressed as the probability of receiving a z-value . an absolute value at least as great as the one we actually observed in the sample data.P-value, or probability value, is the likelihood that a statistic will be at least this distant from the mean if the null hypothesis is assumed to be true. So it can be thought of as a conditional probability, to put it another way.For a lower tail test, the test statistic z is determined to be zero that means
P(z<0)
Then p-value is
p-value = P(z<0) = 0.5 (From z score table )

You are deciding between two cars with different engines and want the bigger
of the two. One engine displaces 350 cubic inches. The other displaces 5,500
cubic centimeters. Check all of the reasonable approaches to solving this
question.
Answers
The bigger engine is larger than the smaller one by 235.4724 cubic centimeters.
How is the bigger engine larger than other?We know that 1 inch=2.54 centimeters
Then 1 cubic inches-(2.54)^3 cubic centimeters
We have that:
⇒ 1 cubic inches=(2.54)3 = 16.3870 cubic centimeters
⇒350 cubic inches= 350 x 16.3870 = 5735.4724 cubic centimeters
Since, the other displaces 5,500 cubic centimeters and 5735.4724< 5500. The difference between them is:
= 5735.4724 - 5500
= 235.4724
Hence, the bigger engine larger than the smaller one by 235.4724 cubic centimeters.

Which of the following describes the transformation from Figure 1 to Figure 2?
Answers
A statement which best describe the transformation from Figure 1 to Figure 2 is: C. reflection over the y-axis.
What is a reflection?In Mathematics, a reflection can be defined as a type of transformation which moves every point of the geometric figure by producing a flipped, but mirror image of the geometric figure.
In Geometry, a reflection over the y-axis (y = x) is given by this transformation rule (x, y) → (-x, y). This ultimately implies that, a reflection over the y-axis would maintain the same y-coordinate while the sign of the x-coordinate changes from positive to negative or negative to positive.
By applying a reflection over the y-axis to the coordinates of figure 1, the coordinates of figure 2 include the following:
(x, y) → (-x, y)
Coordinate A = (-6, 5) → Coordinate A' = (-(-6), 5) = (6, 5).
Coordinate B = (-4, 5) → Coordinate B' = (-(-4), 5) = (4, 5).
Coordinate C = (-3, 5) → Coordinate C' = (-(-3), 5) = (3, 5).
Coordinate D = (-5, 4) → Coordinate D' = (-(-5), 4) = (5, 4).
Coordinate E = (-5, 3) → Coordinate E' = (-(-5), 3) = (5, 3).
Coordinate F = (-7, 3) → Coordinate F' = (-(-7), 3) = (7, 3).

Complete the sentence by selecting the correct word from the drop down choices.
Maria sells each scarf for Choose... ✓ or
Answers
The price that Maura sell each scarf would be =$33. Maura sells each scarf for $33. That is option A.
How to calculate the selling price of each scarf?To calculate the amount of money that Maura spends on each scarf the following is carried out.
The amount of money that she spends on the scarf material = $5.50
The percentage selling price of each scarf = 600% of $5.50
That is ;
= 600/100 × 5.50/1
= 3300/100
= $33.
Therefore, each price that is sold by Maura would probably cost a total of $33.

Answers
A point estimate is the value of a statistic that estimates the value of a parameter. Question 2 is false and question 3 is true.
Question 1: A point estimate is the value of a statistic that estimates the value of a parameter.A point estimate is a single number that is used to estimate the value of an unknown parameter of a population, such as a population mean or proportion
Question 2: False
Mu (μ) is not used to estimate X. Mu represents the population mean, while X represents the sample mean. The sample mean, X, is used as an estimate of the population mean, μ.
Question 3: True
Beta (β) is indeed used to estimate the population proportion (p) when conducting hypothesis testing on a sample. Beta represents the probability of making a Type II error, which occurs when we fail to reject a null hypothesis that is actually false. By calculating the probability of a Type II error, we indirectly estimate the population proportion, p, under certain conditions and assumptions.

altitude, h, be? Round to the
nearest tenth of a mile.
Answers
The plane’s altitude will be approximately 6,336 feet when it has flown over 7 miles of ground and climbed at a 9° angle.
What is meant by miles?
Miles are a unit of distance used in the United States and some other countries, equal to 5,280 feet or 1.609 kilometres. Miles are commonly used to measure distances between cities, countries, and other geographical locations.
What is meant by angle?
A geometric shape known as an angle is created by two rays or line segments that have a similar terminal (referred to as the vertex). Angles can be expressed as radians or degrees and are used to describe how lines and shapes are oriented, situated, and related to one another. Angles can be categorised according to their size and shape as acute, right, obtuse, straight, or reflex.
According to the given information
The problem can be solved using trigonometry 1. The altitude of the plane can be calculated using the tangent function as follows: tan(9°) = h/7 h = 7 tan(9°) ≈ 1.2 miles ≈ 6,336 feet
Therefore, the plane’s altitude will be approximately 6,336 feet when it has flown over 7 miles of ground and climbed at a 9° angle.

an inverted cone has a height of 11 inches and an initial radius of 18 inches. the volume of the inverted cone is decreasing at a rate of 541 cubic inches per second, with the height being held constant. what is the rate of change of the radius, in inches per second, when the radius is 5 inches?
Answers
Answer:
-4.697 in/s
Step-by-step explanation:
You want to know the rate of change of radius of a cone 11 inches high with a radius of 5 inches and a volume that is decreasing at the rate of 541 cubic inches per second.
VolumeThe volume of a cone is given by ...
V = π/3r²h
The rate of change is found by implicit differentiation:
V' = (π/3)((2rr')h +r²h')
Here, the height is constant, so h' = 0. Solving for r', we find ...
r' = 3V'/(2πrh)
ApplicationUsing the given values of V', r, and h, we find the rate of change of radius to be ...
r' = 3(-541 in³/s)/(2π(5 in)(11 in)) = -1623/(110π) in/s ≈ -4.69652 in/s
The radius is decreasing at about -4.697 inches per second.
__
Additional comment
The initial radius of the cone is irrelevant to the problem, since we want to know the rate of change at a specific different radius. Whether the cone is inverted or not is also irrelevant to its volume.
