Which shape has symmetry
Answer:
E.Step-by-step explanation:
__________________________________________________________
The answer is E because,
__________________________________________________________
A is not symmetric because it is indistinguishable from its transformed image.
__________________________________________________________
B is also not symmetric because it is indistinguishable from its transformed image
__________________________________________________________
C is not the answer because it looks like a blob and it's indistinguishable.
__________________________________________________________
D is not the answer because a shape is not a mountain and it is indistinguishable from a form we know.
__________________________________________________________
E is correct because it has one line of symmetry and it is distinguishable, which means that we know it is a shape that has symmetry.

The shape of a heart is said to be symmetric. Option e is the correct answer.
What is symmetry?When two objects are cut into two halves from their axis then the two parts should look the same in size and shape so they will be called as symmetric to each other.
Here we can see in the question that the shape of the heart when cut from its central axis its two parts will be equal in shape and size so the shape of a heart is symmetric.
Therefore the shape of a heart is said to be symmetric. Option e is the correct answer.

If the population of a certain county was 100,000 in 1998 and 110,429 in 2008, and if the formulay = P0ehtapplies to the growth of the county's population, estimate the population of the county in 2023. (P0 is the initial population. Round your value of h to four decimal places. Round your answer to the nearest whole number.)
Answer:
126807 people
Step-by-step explanation:
Given;
P= Poe^ht
Where;
P= population at time t
Po= population at the beginning
h= growth constant
t= time
1998- 2008 is ten years.
110429= 100,000e^10h
1.1 = e^10h
ln(1.1) = lne^10h
0.095 = 10h
h= 0.0095
In 2023, t = 25 years
P= 100,000e^(0.0095 × 25)
P= 126807 people

company A
company B
company C
All companies have a probability of loss.
Answer:
Company B
Step-by-step explanation:
Company A is the best investment decision. Why? its total probability of profit and breaking even is the greatest of all the three companies. Also, its the probability of making a profit is higher than that of making a loss.
How the Investment Decision was madeThe chance that a company will not make a loss is the sum of its break-even probability and that of its profitability. This probability for all companies is given below:
Company A = 50 + 34 = 84%Company B = 40 + 28 = 68%Company C = 17 + 60 = 77%The probability of Loss is highest in Company B so this is not the best option.
The probability of profit is lowest in Company C so this is not the best option. Hence, A is the best investment decision.

Beck finished 30% of his homework in 12 minutes. How many minutes will it take him to complete all of his homework?
Part A
Let m = the number of minutes it will take Beck to finish his homework.
Choose the equation that can be used to find a solution to the problem.
A) 0.03m = 12
B) 12m = 0.3
C) m = 0.3 × 12
D) 0.3m = 12
Part B
Use the expression from Part A to find the total number of minutes it will take Beck to complete all of his homework.
Enter your answer in the box.
_________minutes
Answer: The answer is 40 minutes.
Equation: If m is the total number of minutes it takes him to complete his homework, 30% of m is given by 0.3m. Since 30% was done in 12 minutes, we have 0.3m=12.

Step 1: Define
x² = 625
Step 2: Solve for x
Square root both sides: x = ±25Step 3: Check
Plug in x into the original equation to verify it's a solution.
x = -25
Substitute in x: (-25)² = 625Exponents: 625 = 625Here we see that 625 does indeed equal 625.
∴ x = -25 is a solution to the equation.
x = 25
Substitute in x: 25² = 625Exponents: 625 = 625Here we see that 625 does indeed equal 625.
∴ x = 25 is a solution to the equation.

Answer:
x- intercept (5, 0)
y- intercept (0, 2)
Step-by-step explanation:
x- intercept occurs at y= 0.
To find the x- intercept of the linear equation, substitute y= 0 into the equation.
4x +10y= 20
When y= 0,
4x +10(0)= 20
4x= 20
x= 20 ÷4 (÷4 on both sides)
x= 5
Thus, the x-intercept is (5, 0).
y-intercept occurs at x= 0.
4x +10y= 20
When x= 0,
4(0) +10y= 20
10y= 20
y= 20 ÷10 (÷10 on both sides)
y= 2
Thus, the y-intercept is (0, 2).

use the rational root theoremtry values of x=±1narrow the search using Descartes' rule of signsestimate maximum or minimum root values__
1. Rational roots will be factors of 10, so ±1, ±2, ±5, or ±10. The signs are all positive, so there are no positive real roots. The sum of odd-degree coefficients is the same as the sum of even-degree coefficients, so -1 is one of the roots. Removing that using synthetic division gives you ...
f(x) = (x +1)(x^2 +11 +10)
The quadratic (more or less obviously) factors as (x+1)(x+10), so the complete factorization is ...
f(x) = (x +1)^2(x +10)
and the zeros are {-10, -1, -1}.
__
2. Rational roots will be factors of 18, so will be ±1, ±2, ±3, ±6, ±9, ±18. The sum of coefficients is 0, so x=1 is a root. The rule of signs tells you that there are 2 positive real roots, so there is one more positive real root. Synthetic division tells you the factoring so far is ...
f(x) = (x -1)(x^3 +2x^2 -9x -18)
We note that the first two coefficients have the same ratio as the last two, so we can factor by grouping.
x^3 +2x^2 -9x -18 = x^2(x +2) -9(x +2) = (x^2 -9)(x +2)
Factoring the difference of squares gives you the complete factorization, hence all of the roots. (The zeros are the values of x that make the factors zero.)
f(x) = (x -1)(x +2)(x -3)(x +3)
The zeros are {-3, -2, 1, 3}.

eighteen individuals who use a particular form of social media were assigned a new user interface to use when logging into their accounts. after using the new user interface for a week, each individual was asked to rate how easy or hard the new user interface was to use on a scale from 1 (extremely easy) to 9 (extremely hard). which of the following correctly identifies why this is not a well designed experiment?
A. There was a lack of control because not all individuals in the study used login passwords of the same length
B. The individuals may not have been randomly selected
C. There was not enough replication because the individuals used the new user interface for only one week.
D. there was a lack of control because not all individuals in the study use social media
E. the study was not comparative- only one treatment was used.
Answer:
E: The study was not comparative—only one treatment was used.
Step-by-step explanation:
Well-designed experiments should involve comparisons of at least two treatment groups, one of which could be a control group.
A well-designed experiment investigates design features that achieve the research to rule out sources of variation as reasons for the observed relationship between both the independent variable(s) and the predictor variables.
Studies that are well should include a comparison of at least two treatments, one of which may be a controlled study.Eighteen people using a specific type of social media are given a different user interface to utilize when login onto their account. After a day of just using the new user interface, each participant was asked to rate as difficult or easy it was to use the new interface on a scale of 1 to 9.The study was not properly comparative since it identified just one treatment that was not used as the well-designed study.Therefore, the final answer is "Option E".
