Answer:

Identity

Step-by-step explanation:

Conditional equation, an identity, or a contradiction.

Conditional equation: Two sides are equal for some value of x.

Identity: Two sides are equal for every value of x.

Contradiction: We have 0x = number that is not 0.

4x+5x−15=9x−10−5

Lets solve

[tex]4x + 5x - 15 = 9x - 10 - 5[/tex]

[tex]9x - 15 = 9x - 15[/tex]

Equal on both sides, so identity.

Answer:

conditional equation

Step-by-step explanation:

Collecting terms on both sides, we get

−4+3x−5x−2x−4=−1−10+x=x−11

Subtracting x and adding 4 to both sides of the equation, we get

−3x=−7

This can be solved by dividing by −3 on both sides of the equation, which gives a unique solution of 73. So, this is a conditional equation.

Answer:

-48.015

Step-by-step explanation

Answer:

The student incorrectly simplified [tex]30ab\sqrt{2a}+20a\sqrt{2a}[/tex] .

Thus, option D is correct.

Step-by-step explanation:

The formula to determine the Perimeter of a rectangle of width w and length l is expressed as:

[tex]P = 2l + 2w[/tex]

In other words, the perimeter can be determined by multiplying the length and width by 2 and adding the result.

In our case, the dimensions of a rectangle are [tex]\sqrt{50a^3b^2}[/tex]  and  [tex]\sqrt{200a^3}\:\:[/tex].

Here is the student's solution:

[tex]2\sqrt{50a^3b^2}+2\sqrt{200a^3}=2\cdot 5ab\sqrt{2a}+2\cdot 10a\sqrt{2a}[/tex]

                                 [tex]=10ab\sqrt{2a}+20a\sqrt{2a}[/tex]

                                 [tex]=30ab\sqrt{2a}[/tex]          

The student made an error in calculating [tex]30ab\sqrt{2a}+20a\sqrt{2a}[/tex] , because [tex]30ab\sqrt{2a}+20a\sqrt{2a}[/tex] are not like terms.

Hence, [tex]30ab\sqrt{2a}+20a\sqrt{2a}[/tex] can not be simplified to [tex]30ab\sqrt{2a}[/tex]

Therefore, the student incorrectly simplified [tex]30ab\sqrt{2a}+20a\sqrt{2a}[/tex] .

Thus, option D is correct.

Here is the correct Solution:

[tex]2\sqrt{50a^3b^2}+2\sqrt{200a^3}=2\cdot 5ab\sqrt{2a}+2\cdot 10a\sqrt{2a}[/tex]

                                 [tex]=10ab\sqrt{2a}+20a\sqrt{2a}[/tex]

Answer:

D. The student incorrectly simplified 10ab sqrt2a+ 20a sqrt2a

Answer:

H0 : μ2004 - μ2000 = 0

Step-by-step explanation:

Given the data:

Year ________: 2000 ___ 2004

Mean ________ 27.34 ___ 48.12

Std. Dev _______10.11 ____ 19.23

Unweighted n 43 54

The hypothesis is to test if there was a significant difference in the average number of hours worked in a week from 2000 to 2004 ;

Hence, the null hypothesis will negate the hypothesis, that is there is no difference in the average hours worked in a week from 2000 to 2004

Null hypothesis ; H0 : μ2 - μ1 = 0

Alternative hypothesis ; H1 : μ2 - μ1 ≠ 0

Null hypothesis suggest that there is no significant relationship exist in the given set of single observed variable.. As the null hypothesis negate the hypothesis. Hence the difference is zero and hypothesis for the given problem is,

[tex]H_0; (\mu_1-\mu_2)=0[/tex]

[tex]H_a; (\mu_1-\mu_2)\neq 0[/tex]

For year                     2000         2004

Mean                          27.34          48.12

Standard Deviation   10.11          19.23

Unweighted n             43              54

Null hypothesis suggest that there is no significant relationship exist in the given set of single observed variable.

Now the Analyst want to know if there was a significant difference in the average of hours worked in a week from year 2000 to 2004.

To detect a difference (if there it is) between the average of hours worked in a week from 2000 to 2000, it should be test the null hypothesis that there is no difference between the means against the alternative hypothesis. Therefore,

[tex]H_0; (\mu_1-\mu_2)=D_0=0[/tex]

Versus

[tex]H_a; (\mu_1-\mu_2)\neq 0[/tex]

As the null hypothesis negate the hypothesis. Hence the difference is zero and hypothesis for the given problem is,

[tex]H_0; (\mu_1-\mu_2)=0[/tex]

[tex]H_a; (\mu_1-\mu_2)\neq 0[/tex]

Answer:

So a whole number answer would be 3 per person with a remainder of 2.

or

It would be a mixed number and be 3 1/2 per person.

Step-by-step explanation:

Well you and your 3 friends are 4 people total.

4 is not a multiple of 14 so if you want to share equally youll have some leftover cause im assuming the answer must be a whole number and not a decimal.

But the most you and your friends can share equally is 3 per person. Since 4 people with 3 packs each (4 x 3) is 12 packs total with 2 packs leftover.

If you want to split these packs among the 4 of you, you can do 4/2 to get 1/2 a pack for each of you guys to share.

So a whole number answer would be 3 per person with a remainder of 2.

or

It would be a mixed number and be 3 1/2 per person.

Hope this helps!

I say that A best represents the equation.

The reason I say this is because the equation (y= x + 15)  can be explained like this.

y= Total amount of candy (in this case since it's based on A)

x= Amount found (normally would be called earned)

15= starting amount (aka initial value)

So since each student started with 15 you would add that on to X= the total amount found. Then after that the total value (y) would have been represented by the equation X + 15.

All in all A best represents the equation Y= X + 15.

Hope this helps.

Answer:

21 + 7b

Step-by-step explanation:

We have the expression 7(3 + b) and are being asked the answer.

Our expression has a number out of a certain parenthesis, when this occurs, this means that we must distribute the number outside the parenthesis to the numbers inside. Do as following :

7(3 + b)

(7(3) + 7(b))

21 + 7b

Step-by-step explanation:

Answer:

[tex]q = -6p + 104[/tex]

Step-by-step explanation:

Linear function:

A linear function has the following format:

[tex]q = mp + b[/tex]

In which m is the slope and b is the q-intercept.

One week you charged $4 per guest and averaged 80 guests per night. The next week you charged $10 per guest and averaged 44 guests per night.

This means that we have these following points: (4,80), (10,44).

Finding the slope:

With a pair of points, the slope is given by the change in q divided by the change in p.

Change in q: 44 - 80 = -36

Change in p: 10 - 4 = 6

Slope: [tex]m = \frac{-36}{6} = -6[/tex]

So

[tex]q = -6p + b[/tex]

Finding b:

We replace one of the points. Replacing (4,80).

[tex]q = -6p + b[/tex]

[tex]80 = -6*4 + b[/tex]

[tex]b = 104[/tex]

So

[tex]q = -6p + 104[/tex]

Answer:

B. Observing that five out of the next ten customers at a hotdog stand order hot peppers given that the probability of ordering hot peppers is 0.18.

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

Option A:

No, since it is not the probability, or percentage of students that have ear pircings, it is the number, which can assume values larger than 1.

Option B:

Yes, since it is a probability, each customer is independent of other customers, and in each trial, there are only two possible outcomes. This is the correct answer.

Option C:

No, this is called inverse binomial, as we want to find the number of customers until one does something, not the probability of a number of customers doing something.
