To draw a conclusion, a statistical analysis with a significance level (alpha) of 0.02 can be applied to compare the results.treated samples consistently show lower shrinkage temperatures compared to the control samples

In this study, the aim is to prove that electrical stimulation improves meat tenderness. Connective tissue (collagen) from beef steaks was examined, as lower collagen shrinkage temperature indicates higher tenderness.

The beef carcasses were split, with one side subjected to electrical current and the other side untreated as a control. Steak samples were cut from each side and tested for tenderness by determining the collagen shrinkage temperature.

I, it suggests that electrical stimulation does improve meat tenderness.

In this case, we are to determine the probability of selecting two even numbers. This can be solved as follows:There are six even numbers: {2, 4, 6, 8, 10, 12}.We can use the concept of conditional probability since the first event affects the probability of the second event. This can be expressed as follows:

In this case, P(A) represents the probability of selecting an even number, and P(B|A) represents the probability of selecting an even number given that the first card selected was even. P(A) = 6/12 = 1/2 (there are six even numbers and twelve cards in total)P(B|A) = 5/11 (there are five even numbers left in the box after the first even number is selected, and eleven cards are left in total).

The probability of selecting two even numbers can be found by multiplying these probabilities: P(A) x P(B|A) = (1/2) x (5/11) = 5/22Therefore, the probability of selecting two even numbers is 5/22.Answer: 5/22

The two transformations that can be applied are a horizontal translation of 2 units to the left or a vertical translation of 10 units up.

A general linear equation is written as:

f(x) = a*x + b

Here we can see that the two lines are parallel, so the transformations that can be applied are a vertical or an horizontal translation of N units.

The vertical translation is written as:

g(x) = f(x) + N

The horizontal one is:

g(x) = f(x + N).

B) now we need to solve this for both both of the transformations.

i) We can see that f(0) = -2 and g(0) = 8

For the first transformation we have:

g(0) =f(0) + N = 8

       = -2 + N = 8

                  N = 8 +2 = 10

For the second transformation:

g(0) = f(0 + N) = 8

We can see that f(x) = 8 for x = 2, then in this case N = 2.

Then we can have a translation of 2 units to the left or 10 units up.

Step-by-step explanation:

It looks like the particle's acceleration is

a(t) = 3t²

and we're given the initial velocity and position to be v(1) = 2 and x(1) = 6.

(a) By the fundamental theorem of calculus, the velocity at time t is

v(t) = v(1) + ∫₁ᵗ a(u) du

v(t) = 2 + ∫₁ᵗ 3u² du

v(t) = 2 + u³ |₁ᵗ

v(t) = 2 + (t³ - 1³)

v(t) = t³ + 1

(b) Use the theorem again to get the position at time t,

x(t) = x(1) + ∫₁ᵗ v(u) du

x(t) = 6 + ∫₁ᵗ (u³ + 1) du

x(t) = 6 + (1/4 u⁴ + u) |₁ᵗ

x(t) = 6 + (1/4 t⁴ + t - 1/4 • 1⁴ - 1)

x(t) = 1/4 t⁴ + t + 19/4

(c) The position of the particle at t = e is

x(e) = 1/4 e⁴ + e + 19/4

The measure of the angle m∠ZYX of the trapezoid is equal to 139°

A trapezoid is a quadrilateral with two parallel sides. The parallel sides are called the bases of the trapezoid, and the other two sides are called the legs. The adjacent angles of the trapezium are supplementary, so their sum is equal to 180°.

3x + 19 + x + 1 = 180°

4x + 20 = 180°

4x = 180 - 20 {collect like terms}

4x = 160

x = 160/4 {divide through by 4}

x = 40

m∠ZYX = 3(40) + 19 = 139°.

WXYZ is a trapezoid. Equation used to solve for x is (3x + 19) + (x + 1) = 180° because the angles m∠XYZ and m∠WXY are adjacent angles.

Step-by-step explanation:

Given:

\( f(x) = 4x^2 - 3 \)

Required:

Average range of change from 3 to 9

SOLUTION:

Step 1:

Find f(3) and f(9):

To find f(3), replace x with 3 in the given function

\( f(3) = 4(3)^2 - 3 \)

\( f(3) = 4(9) - 3 \)

\( f(3) = 36 - 3 \)

\( f(3) = 33 \)

To find f(9), replace x with 9 in the given function

\( f(9) = 4(9)^2 - 3 \)

\( f(9) = 4(81) - 3 \)

\( f(9) = 324 - 3 \)

\( f(9) = 321 \)

Average rate of change = \( \frac{f(b) - f(a)}{b - a} \)

Where,

\( a = 3, f(a) = 33 \)

\( b = 9, f(b) = 321 \)

Plug in the values into the formula for average rate of change.

\( = \frac{321 - 33}{9 - 3} \)

\( = \frac{288}{6} \)

\( = 44 \)

Average rate of change = 44

Answer:

The expected number of ticket holders that will fail to show for the flight is 13.9.

Step-by-step explanation:

For each ticket holder, there are only two possible outcomes. Either they fail to show up for the flight, or they do not. Ticket holders are independent. This means that we use the binomial probability distribution to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The expected value of the binomial distribution is:

\(E(X) = np\)

5% of passengers fail to show for flights

This means that \(p = 0.05\)

278 tickets sold

This means that \(n = 278\)

What is the expected number of ticket holders that will fail to show for the flight?

\(E(X) = np = 278*0.05 = 13.9\)

The expected number of ticket holders that will fail to show for the flight is 13.9.

This celphone plan has a fixed cost of $15, this means that regarding if you use it or not, you'll pay at least $15.

Also, added to those fixed costs, you pay $0.10 per minute for phone calls.

Acording to the text, the bill for last month was $32.50, first step is to remove the fixed charges to know how much was spent on phone calls:

$32.50-$15= $17.5

Now using cross multiplication you can calculate how many minutes she talked to spend $17.5:

$0.10____1min

$17.50___xmin

She talked 175 minutes over the phone

Answer: E: The number of books a person finished reading last month

Step-by-step explanation:

First, a discrete variable is a variable that only can take some given values in a set, the discrete variables are usually not dense, and a continuous variable is a variable that can take any value in a range (where the accepted values are dense).

So, for example, the set of the natural numbers is discrete, and the set of the real numbers can represent a continuous variable.

Here the only option that is really discrete will be the number of books that a person finished reading last month because here only positive whole numbers are accepted (you can not finish a 0.454 of a book)

The other options are continuous because all are classical measures.

For example, the weight of a person can jump between:

75.6kg and 75.7kg.

So you could think that this is discrete because the values between 75.6kg and 75.7g are not shown with our measuring device, but those will be added in the error of the measure because the weights between 75.6kg and 75.7kg are actually possible, so they must be accepted.

Option E is right.

A. The height of a person. Height is a continuous variable.

B . The weight of a person. Weight is a continuous variable.

C. The length of a person’s arm span. Length is a continuous variable.

D. The time it takes for a person to solve a puzzle. Time is a continuous variable.

E. The number of books a person finished reading last month. The number of books is discrete variable.

Answer:

Natasha can wrap 128 gifts in total

Step-by-step explanation:

Let us use the ratio method to solve the question

∵ Natasha has 240 square feet of wrapping paper

∵ Natasha can wrap 8 gifts with 15 square feet

→ By using the ratio method

→  Gift  :  square feet

→   8     :  15

→   x      :  240

→ By using cross multiplication

∵ x × 15 = 8 × 240

∴ 15x = 1920

→ Divide both sides by 15

∵ x = 128

∵ x represents the number of gifts

∴ Natasha can wrap 128 gifts in total

Step-by-step explanation:

From left to right, top to bottom

1. 5 x 10 = 50

3. 5 x 6 = 30

For the triangles since there is 2 of them and there the same we play it like there is 1 square

4 & 5. 8 x 6 = 48

Now add all them

50 + 40 + 30 + 48

50 + 40 = 90

30 + 48 = 78

90 + 78 = 168

Answer:

Step-by-step explanation:

5*10 = 50 (left rectangle)

8*6 = 48 (top and bottom triangles, not dividing by 2 as there is two of that exact shape)

5*8 = 40 (middle rectangle)

6*5 = 30 (right rectangle)
