Maria has to mail 3 letters, each costing $0.41, totaling to $1.23. She gives the clerk $2.00, so the change she will get back is $2.00 - $1.23 = $0.77.

This problem is about simple arithmetic and money management. Maria has to mail 3 letters, each costing $0.41. This means that the total expense that Maria has to pay is $0.41 * 3, which equals $1.23. Maria gives the clerk $2.00, so to find out the change, subtract the total cost of the letters ($1.23) from the amount she gave to the clerk ($2.00). So, the change Maria will get back is $2.00 - $1.23 = $0.77.

Answer:

[tex]x-2[/tex] is not a factor of [tex]p(x)=4x^2-3x+22[/tex].

Step-by-step explanation:

According to the factor theorem, if [tex]x-a[/tex] is a factor of [tex]p(x)[/tex], then [tex]p(a)=0[/tex].

Let [tex]p(x)=4x^2-3x+22[/tex]. If  [tex]x-2[/tex] is a factor of [tex]p(x)=4x^2-3x+22[/tex], then [tex]p(2)=0[/tex].

Let us plug in [tex]x=2[/tex] in to the function to see if it will give us zero.

[tex]p(2)=4(2)^2-3(2)+22[/tex]

We simplify to obtain,

[tex]p(2)=4(4)-3(2)+22[/tex]

[tex]p(2)=16-6+22[/tex]

[tex]p(2)=10+22[/tex]

[tex]p(2)=32[/tex]

Since  [tex]p(2)\ne0[/tex], [tex]x-2[/tex] is not a factor of [tex]p(x)=4x^2-3x+22[/tex].

According to the Factor Theorem, 'x - 2' is not a factor of the polynomial '4x^2 - 3x + 22'. This determination was made by plugging '2' into the second polynomial and finding that it does not result in zero.

For a polynomial P(x), the Factor Theorem states that if you plug a value 'a' into the polynomial and get zero (P(a) = 0), then x-a is a factor of that polynomial. In this case, you are asked to determine whether 'x - 2' is a factor of the quadratic function '4x^2 - 3x + 22'.

To do so, according to the Factor Theorem, plug the value '2' into the second polynomial function, so we have 4*(2)^2 - 3*(2) + 22 = 16 - 6 + 22 = 32. Because this does not equal zero, we can conclude that 'x - 2' is not a factor of the second polynomial '4x^2 - 3x + 22' based on the Factor Theorem.

Let X be the number of tail when a coin is flipped n number of times. Let n is the number of times a coin is flipped. Let p be the probability of getting tail on any flip of coin.

Here as coin is fair coin the chance of getting head or tail at any flip is 1/2.

n=75, p =0.5

From given information X follows Binomial distribution with n=75 and p=0.5

The probability that getting tail 35 or fewer times is

P(X ≤ 35) = P(X=35) + P(X=34) + P(X=33) + ....+ P(X=2) + P(x=1)

The Binomial probability is calculated using probability function

[tex] P(X=k) = (nCk) p^{k} (1-p) ^{n-k} [/tex]

For given parameters n=75 and p=0.5 the probability of getting X=k is

[tex] P(X=k) = (75Ck) 0.5^{k} (1-0.5) ^{75-k} [/tex]

Using excel function to find cumulative binomial probability for x=1 to 35 is

=BINOM.DIST(35,75,0.5,1) = 0.322

The probability there will be 35 or fewer tails is 0.322

The percentage of getting 35 or fewer tails is 32.2%

The dimensions of the rectangle given by the trinomial (x² + x – 42) are 7 and 6, which are derived by factoring the trinomial and applying the quadratic formula.

To find the possible dimensions of the rectangle, we start by factoring the trinomial that represents the area of the rectangle, namely x² + x – 42.

This can be factored as (x + 7)(x - 6), which are the roots of the quadratic equation when set to equal zero.

The roots, or solutions to this equation, can be calculated using the quadratic formula, -b ± √b² - 4ac 2a, which includes squaring the coefficient of the x-term, subtracting four times the product of the remaining coefficients, and dividing the result by twice the leading coefficient.

In this case, the dimensions that correspond to these roots, namely length and width, are 7 and -6. However, since dimensions cannot be negative, we disregard -6. Therefore, the possible dimensions of the rectangle are 7 and 6.

The solution is, x = -243 is the value of (-3)^-5=1/x.

The algebraic equations are those which are valid for all values of variables in them are called algebraic identities.

Here we have:

Given that,

(-3)^-5=1/x

now, we have to simplify this expression, to get the value o x .

so, we get,

1/(-3)^5=1/x

or, (-3)^5=x

or, x = -243

Hence the value of the expression (-3)^-5=1/x , is x= -243.

Answer: the perimeter of JKL is 84

ik this is rlly late but to help anyone else who gets this question:

This is an equilateral triangle, so the adjacent length is gonna be the same value as its corresponding length that was listed

JA = 10

JB = JA, JB is also 10

JA + JB (10+10) = 20

AL = 23

LC = AL, LC is also 23

AL + LC (23+23) = 46

CK = 9

KB = CK, KB is also 9

CK + KB (9+9) = 18

add all those up:

We have been given a system of inequalities and an objective function.

The inequalities are given as:

[tex]y\leq 2x\\ x+y\leq 45\\ x\leq 30\\[/tex]

And the objective function is given as:

[tex]P=25x+20y[/tex]

In order to find the minimum value of the objective function at the given feasible region, we need to first graph the region.

The graph of the region is shown below:

From the graph, we can see that corner points of the feasible region are:

(x,y) = (15,30),(30,15) and (30,60).

Now we will evaluate the value of the objective function at each of these corner points and then we will compare which of those values is minimum.

[tex]\text{At (15,30)}\Leftrightarrow P=25\cdot 15+20\cdot 30=975\\ \text{At (30,15)}\Leftrightarrow P=25\cdot 30+20\cdot 15=1050\\ \text{At (30,60)}\Leftrightarrow P=25\cdot 30+20\cdot 60=1950\\[/tex]

Hence the minimum value of objective function is 975 and it occurs at x = 15 and y = 30

Answer:

The minimum value =

975

and occurs when x =

In this mathematical context, the inequality 20 + 6x > 100 can help Adrian find out the number of weeks he needs to continue his weekly addition of 6 cards to his sports card collection to exceed 100 cards in total.

The subject of this question is Mathematics and it appears to be at a Middle School level. The problem involves understanding and using linear equations and inequalities.

In this situation, Adrian starts with 20 cards and adds 6 more each week. So his total number of cards is represented by the equation 20 + 6x, where x is the number of weeks. If he wants to have more than 100 cards, we set up an inequality like this:

20 + 6x > 100

Thus, the inequality 20 + 6x > 100 allows Adrian to calculate the number of weeks x he needs to continue adding cards to his collection in order to exceed 100 cards total.
