Since Maya is estimating the product of 88 and 12, the statements that are true include the following:

In order to determine the statements that are true, we would have to evaluate each of the statement as follows:

"If she rounds both values to the nearest ten, her estimate will be 800."

Rounding up 88 and 12 to the nearest ten, we have the following:

Rounded up number = 88 ≈ 90

Rounded up number = 12 ≈ 10

Therefore, the product of 90 and 10 is given by:

Product = 90 × 10

Product = 900.

"If she rounds 88 to the nearest hundred and 12 to the nearest ten, her estimate will be 1,000."

Rounding up 88 to the nearest hundred, we have the following:

Rounded up number = 88 ≈ 100

Rounding up 12 to the nearest ten, we have the following:

Rounded up number = 12 ≈ 10

Therefore, the product of 100 and 10 is given by:

Product = 100 × 10

Product = 1,000.

In this context, we can reasonably and logically deduce only two statements are true while all of the other statements are false and incorrect.

There are 630 more strings of ten letters that do not include the consecutive letter stts.

Total number of combinations possible with 10 letters =2∧10

                                                                                          =1024

Calculating using inclusion method;

There are 7 possible spots for the 4 characters, from 1-4 through 7-10, and 26 options for the remaining 6 slots if we have a specific 4 character string that fits within a range of 10 characters. Then, for the double counts, we can either have the strings joined (1-7, 2-8, 3-9, and 4-10), with 23 other values, equaling 4*8=32, or the strings separated (2-5 and 6-9, 7-10, or 3-6, 7-10, equaling 6), with 22 = 4 other values, equaling 6*4 = 24, and one 10-character sequence that contained the pattern three times. STTSTTSTTS.

Number of combination containing consecutive letter stts will be

= 448 - (32 + 24) + 1

= 393.

Then,

Total Strings without the sequence stts = 1024 - 393

                                                                    = 631

Since, one is already provided in the question 631-1=630 more strings can be formed.

There are 19 randomly selected Americans must be surveyed, if we want to estimate 99% confidence interval for the true proportion of Americans who support the gun control in 2018 with a 0.36 margin of error

randomly selected americans must be surveyed can be calculate as follows:

If the prior population proportion is unavailable then the formula to find the sample size is given by :

[tex]n= 0.25(\frac{z*}{E} )^{2}[/tex]where,

z* = Critical z-value

E = margin of error

Let p be the proportion of Americans who support the gun control in 2018.

As per given , we have

Confidence level = 92%

The critical z-value for 92% confidence interval is 1.75 ( BY z-table)

Margin of error : E= 0.2

Since there no  prior information about the proportion of Americans who support the gun control in 2018.

So , the required sample size  to estimate 99% confidence interval would be:

[tex]n= 0.25(\frac{1.75}{0,2} )^{2}\\n= 0.25(8.75)^{2} \\n= 0.25 (76.5625)\\n= 19.14[/tex]or 19

Based on the information given, the SuperFast Deluxe machine is the faster copier. This can be determined by calculating the rate of copies for both machines at each time interval. For Quick Copies, we can calculate the rate using the equation c = 1.5t. For the SuperFast Deluxe, it can be simply observed that the number of copies produced increases by 8 each interval. We can then determine that the SuperFast Deluxe creates copies more quickly than the Quick Copies machine. Therefore, the principal should choose the SuperFast Deluxe.

An equation of the parabola that models the cross section of the mirror is y=x²/28.

Given that, a mirror with a parabolic cross section is used to collect sunlight on a pipe located at the focus of the mirror.

A parabola refers to an equation of a curve, such that a point on the curve is equidistant from a fixed point, and a fixed line. The fixed point is called the focus of the parabola, and the fixed line is called the directrix of the parabola.

The pipe is located 7 inches from the vertex of the mirror.

The parabola is open upwards . the vertex of the parabola is (0,0)

and pipe is located 7 inches from the vertex (0,0)

7 inches is the focus of the mirror

The distance between the vertex and the focus = 7

Since parabola is upwards and vertex is (0,0) we use formula 4py=x²

Where p is the distance between the vertex and focus p = 7

Now, 4×7×y=x²

⇒ 28y=x²

Now isolate y by dividing 28 on both sides, we get

y=x²/28

Therefore, an equation of the parabola that models the cross section of the mirror is y=x²/28.

The modified function will be  f(p²) = [tex]p^{4}[/tex] - 3p² +1.

What is a function?
A function is a special kind of relation where each input has exactly one output. In other words, for each input value, the function returns exactly one value. A relation instead of a function is depicted in the above graph as one is mapped to intermediate values. However, if someone were instead mapped to the a single value, the relationship described above would change into a function. Furthermore, output values could match input values exactly. The function machine receives the x-values as input. After finishing its operations, the function machine outputs the y-values. Any function may be the one within.

The given function f(x) = x²-3x+1

So we can replace x ---→ p²

So f(p²) = [tex]p^{4}[/tex] - 3p² +1

Hence the modified function will be  f(p²) = [tex]p^{4}[/tex] - 3p² +1

The preimage of the point C'(x, y) = (- 3, - 10) is the point C(x, y) = (5, - 14).

In this question we find the coordinates of a point that is result of a translation. Translations are examples of rigid transformations, whose vector formula is shown below:

C'(x, y) = C(x, y) + T(x, y)

Where:

Please notice that the original point C(x, y) is the preimage of C'(x, y).

If we know that C'(x, y) = (- 3, - 10) and T(x, y) = (- 8, 4), then the preimage of the point C is:

(- 3, - 10) = C(x, y) + (- 8, 4)

C(x, y) = (- 3, - 10) - (- 8, 4)

C(x, y) = (- 3, - 10) + (8, - 4)

The value of angle E  in the ΔDEF is 121°.

Given,

∠B = (96 + y)°

∠E = (6y - 29)°

EF = BC

AB = DE

AC = DF

Therefore, ΔABC ≅ ΔDEF

So, ∠ABC = ∠DEF or ∠B = ∠E

     96 + y = 6y - 29

      6y - y = 96 + 29

           5y = 125

             y = 125/5

If a and b are disjoint, then the value = 1.

If two events are mutually exclusive then the probability of them happening or occurring simultaneously is by definition zero. However, the described setting is impossible.

Let’s review the situation. At a given point in time there are four possible states of the world:

We know that

Pr(S4) = 0,

since A and B are mutually exclusive. We also know that the probability of A happening is 0.2, which is in states S2 and S4, so

Pr(S2) + Pr(S4) = 0.2.

Moreover, the probability of B happening is 0.8, which is in states S3 and S4, so

Pr(S3) + Pr( S4) = 0.8.

Since PR(S4) = 0, it follows that

P(S2)= 0.2

and

Pr(S3) = 0.8.

However, that means that the probabilities of all possible states do not sum to 1 as they should for a probability distribution, since Pr(S2) + Pr(S3) is already 1. So the problem definition describes an impossible situation.

Hence the answer is if a and b are disjoint, then the value = 1.

The equation 6x²+64x-222 = -8x is in form of (x+6)² = 73

Given: 6x²+64x-222 = -8x

To change the given equation to the form (x+a)² = b, the steps below will be all intermediate steps involved:

6x²+64x-222 = -8x

2(3x²+32x-111) = 2(-4x)

3x²+32x-111 = -4x

3x²+32x+4x-111 = 0

3x²+36x = 111              (Divide through by 3)

x²+12x = 37

Using completing the square by adding the square of half of the coefficient of x to both sides of the equation:

x²+12x+(6)² = 37 +(6)²
