A parabola has a maximum value of 4 at x= -1, a y-intercept of 3, and an x-intercept of 1. The x-intercepts are -3 and 1. So, The second graph is the right one.

We have given that,

A parabola has a maximum value of 4 at x = -1,

A y-intercept of 3, and an x-intercept of 1.

The maximum value of a graph refers to the point on the graph where the y-coordinate has the largest value.

A maximum graph is one that represents the largest value of the y-coordinate on the graph.

So, The second graph is the right one.

Note that when x = 1, y (the maximum) is 4,

and that, The x-intercepts are -3 and 1.

Computational complexity is a branch of theoretical computer science that deals with the analysis and classification of problems based on the amount of computational resources required to solve them, such as time and memory.

It aims to determine the inherent difficulty of solving a problem, independent of any particular algorithm or computer, by characterizing problems according to the complexity classes they belong to, such as P, NP, NP-hard, and NP-complete.

This helps us understand which problems can be solved efficiently and which ones are inherently difficult, and also provides a framework for analyzing the efficiency and trade-offs of different algorithms for solving a problem.

Answer:

6.25 times two equals 12.5

Step-by-step explanation:

If you can earn 8 percent on your money, the prize worth to you is: $76,812.50. To calculate the present value of the prize, we need to determine the current worth of receiving $1000 per month for 9 years, given an 8 percent annual interest rate.

This situation can be evaluated using the concept of the present value of an annuity. The present value of an annuity formula is used to find the current value of a series of future cash flows. In this case, the future cash flows are the $1000 monthly payments for 9 years. By applying the formula, which involves discounting each cash flow back to its present value using the interest rate, we find that the present value of the prize is $76,812.50.

This means that if you were to receive $1000 per month for 9 years and could earn an 8 percent return on your money, the equivalent present value of that prize, received upfront, would be $76,812.50.

Answer:

61

Step-by-step explanation:

If the average of 3 different positive integers, a, b and c, is 50 then:

\(\implies \dfrac{a+b+c}{3}=50\)

If b = 30:

\(\implies \dfrac{a+30+c}{3}=50\)

\(\implies a+30+c=150\)

\(\implies a+c=120\)

If a < b < c then the least possible value of c is one more than the average of a + c.

Average of a + c:

\(\implies \dfrac{a+c}{2}=\dfrac{120}{2}\)

\(\implies \dfrac{a+c}{2}=60\)

So the least possible value of c is 60 + 1 = 61.

Answer:

y= -0.5 x +3

Step-by-step explanation:

at x=0 , y=3

at x=2 , y=2

y= ax+b

b=3

2=2a+3

2a= -1

a= - 0.5

then

y= -0.5 x +3

To find the value of 3(a+b)/2(a-b), we can substitute the given equation a+b/a-b=c into the expression and simplify.

Let's start by substituting the value of c into the expression:

3(a+b)/2(a-b) = 3(c)/2(a-b)

Now, we can substitute the given equation a+b/a-b=c:

3(c)/2(a-b) = 3(c)/(2(c))

Simplifying further:

3(c)/(2(c)) = 3/2

Therefore, the value of 3(a+b)/2(a-b) is 3/2.

total money she has is 32 $

now after buying she has left only with 20$

so she spent 32 - 20 = 12 $

she spent 12 $ for buying 9 packs of noisemaker,

Step-by-step explanation:

The historical rate of defective widgets produced by ACME Corporation was 7%. Approximately, 91.2 is the standard deviations is the point estimate from 7%.

In statistics, standard deviation is a measure of the amount of variation or distribution of a set of values. A low standard deviation indicates that the values ​​tend to be close to the ensemble mean (also called the expected value), while a high standard deviation indicates that the values ​​are spread over a wider range.

The standard deviation can be abbreviated SD, and is most commonly used in mathematical texts and equations with the lowercase Greek letter σ (sigma) for the population standard deviation, or the Latin letter s for the standard deviation of the sample.

The standard deviation of a random variable, sample, population, data set, or probability distribution is the square root of its variance. It is algebraically simpler than the mean absolute deviation, although less robust in practice. A useful property of the standard deviation is that, unlike the variance, it is expressed in the same units as the data.

According to the Question:

Given that:

Defective widgets produced by ACME corporation was 7%

Total sample was 856 widgets.

Therefore, the Standard Deviation estimates from 7% is:

856 of 7% = 91.2

We determine for each of the following groups that (a) G₁ is isomorphic to Z₄. (b) G₂ is not isomorphic to either Z₄ or Z₂ × Z₂.

In order to determine whether each of the given groups G₁ and G₂, of size 4, is isomorphic to Z₄ or Z₂ × Z₂, we need to analyze their properties.

(a) G₁ = {ɛ, (12), (34), (12)(34)} ≤ S₄:
To determine if G₁ is isomorphic to Z₄ or Z₂ × Z₂, we need to examine the structure and properties of Z₄ and Z₂ × Z₂. Z₄ consists of the elements {0, 1, 2, 3}, with addition modulo 4. Z₂ × Z₂ consists of the elements {(0, 0), (0, 1), (1, 0), (1, 1)}, with component-wise addition modulo 2.

By analyzing the group G₁, we can see that it has the same structure as Z₄. Each element in G₁ corresponds to an element in Z₄, and the operation of G₁ matches the addition modulo 4 in Z₄. Therefore, G₁ is isomorphic to Z₄.

(b) G₂ = {ɛ, (13)(24), (1432)}:
Similarly, to determine if G₂ is isomorphic to Z₄ or Z₂ × Z₂, we need to examine their structures. However, G₂ does not contain 4 elements, so it cannot be isomorphic to Z₄. Additionally, the elements in G₂ do not match the structure of Z₂ × Z₂. Therefore, G₂ is not isomorphic to Z₄ or Z₂ × Z₂.

To summarize:
(a) G₁ is isomorphic to Z₄.
(b) G₂ is not isomorphic to either Z₄ or Z₂ × Z₂.

In conclusion, based on the provided information, the pairs of triangles that appear to be congruent are Triangle ABC and Triangle DEF, Triangle BCD and Triangle EFG, and Triangle CDE and Triangle FGH.

To determine which pairs of triangles appear to be congruent, we need to examine their corresponding sides and angles. Congruent triangles have the same shape and size, which means their corresponding sides are equal in length and their corresponding angles are equal in measure.

Let's analyze the given information about the triangles:

Triangle ABC:

Side AB is parallel to side DE and has the same length as side DE.

Side BC is parallel to side EF and has the same length as side EF.

Angle ABC is congruent to angle DEF.

Triangle BCD:

Side BC is parallel to side EF and has the same length as side EF.

Side CD is parallel to side FG and has the same length as side FG.

Angle BCD is congruent to angle EFG.

Triangle CDE:

Side CD is parallel to side FG and has the same length as side FG.

Side DE is parallel to side GH and has the same length as side GH.

Angle CDE is congruent to angle FGH.

From the given information, we can observe that the pairs of triangles that appear to be congruent are:

1. Triangle ABC and Triangle DEF: These triangles have corresponding sides AB and DE, BC and EF, and angle ABC and angle DEF that are congruent.

2. Triangle BCD and Triangle EFG: These triangles have corresponding sides BC and EF, CD and FG, and angle BCD and angle EFG that are congruent.

3. Triangle CDE and Triangle FGH: These triangles have corresponding sides CD and FG, DE and GH, and angle CDE and angle FGH that are congruent.

It is important to note that our observation of apparent congruence is based on the given information. To establish formal congruence, we would need additional information, such as the congruence of a third pair of corresponding sides or angles, to apply congruence postulates or theorems.
