The engineer's improved light bulb likely has a statistically significant longer lifetime than the previous design, with a small but measurable difference of 0.2 hours.

Statistical significance refers to the probability that the observed difference between two groups (in this case, the old light bulbs and the new ones) is not due to chance alone. If the probability is low enough, we can confidently reject the null hypothesis (that there is no difference between the two groups) and conclude that there is a real difference between them.

In this case, a sample size of 40,000 bulbs is quite large, which increases the statistical power of the test and allows for even small differences to be detected as significant. The fact that the new bulb had a slightly longer lifetime of 1,200.2 hours, compared to the old bulb's average lifetime of 1,200 hours, suggests that the engineer's design improvement was successful in making the bulb last longer.

However, it's important to note that while the effect is statistically significant, the practical significance may be less clear. A difference of 0.2 hours may not make a noticeable impact on the bulb's usefulness or longevity in real-world scenarios. Additionally, other factors such as cost or energy efficiency may also need to be considered when evaluating the success of the new design.

You need to use a common denominator in order to add fractions. The first fraction can be changed by multiplying by 3/3. The second fraction remains the same. The sum in the third line uses the two fractions with common denominators (both now have a 12 on the bottom). 8/12 can be reduced by dividing 8 and 12 by 4 to get 2/3 see image

The second digit 7 appears in the position reserved for the ten thousand.

This is further explained below.

In most cases, the location of the number 7 in the second number may be determined by utilizing the multiplication system of numbers. The location of the ten thousand is represented by the second digit of the numeral seven.

It is a given that the first number has a seven in the tenth position.

According to the question that was presented, the first number contains a 7 in the tenth position, which means that the number is 10 times bigger than itself. Now determine the number, seven times ten equals seventy.

In conclusion, Because the value of the seven in the second number is 1,000 times more than the value of the seven in the first number, the value of the second number is 1,000 times greater than the value of the number itself.

7 x 1000 = 7000

As a result, the second digit 7 appears in the position reserved for the ten thousands.

The height that Plant A has grown taller, as regards Plant B, is D. 1 / 2 inch

The height of Plant A is 5 / 6 inches while the height of plant B is 1 / 3 inches. To find how much taller Plant A is than Plant B, you need to subtract the height of Plant B from the height of Plant A.

As these fractions have different denominators, you need to find a common denominator of the bases. This common denominator would be the least common multiple of the denominators of 3 and 6.

This least common multiple is 6. Then divide the common denominator by the denominator of the height and multiply it by the numerator to give ;

:) hope i explained it

Answer: 18-a>25

We can solve the inequality for 'a' by isolating it on one side of the inequality symbol (>).

Starting with:

18 - a > 25

Subtracting 18 from both sides:

a > 7

Dividing by -1 (which changes the direction of the inequality):

a < -7

Step-by-step explanation:

Applying the sine ratio and law of sines, the correct measurements are:

B. m∠B = 15°

E. h ≈ 31.28 ft.

Sine ratio that can be used to determine the side length of a right triangle is, sin ∅ = opposite side/hypotenuse.

Find c using the law of sines:

C = 33°

A = 180 - 48 = 132 [linear pair]

B = 180 - 33 - 132 = 15° [triangle sum theorem]

b = 20 ft

c = ?

Using the law of sines, b/sin B = c/sin C, we have:

20/sin 15 = c/sin 33

(c)(sin 15) = (20)(sin 33)

c = (20 × sin 33)/sin 15

c ≈ 42.09

Use the sine ratio to find h:

∅ = 48°

Hypotenuse = c = 42.09

Opposite = h = ?

sin 48 = h/42.09

h = (sin 48)(42.09)

h ≈ 31.28

The correct measurements are:

B. m∠B = 15°

E. h ≈ 31.28 ft

Answer:

The slope of the line is zero

Step-by-step explanation:

The slope is simply a measure of the degree of tilt that a straight line has in a coordinate system.

To get the slope between two coordinates,  We can make use of this formula.

\(m= \frac{y2-y1}{x2-x1}\)

Where m = slope of the line

x2 = 5

x1 = 2

y2 = c

y1 = c

\(m = \frac{c-c}{5-2}=\frac{0}{3} =0\)

Any number that divides zero will give 0

From this, we can see that the slope of the line is = 0

Answer:

y = - x - 18

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

the equation of a line in point- slope form is

y - b = m (x - a)

m is the slope and (a, b ) a point on the line

y + 3 = - (x + 2) ← is in point- slope form

with slope m = - 1

• Parallel lines have equal slopes , then

y = - x + c ← is the partial equation

to find c substitute (- 10, - 8 ) into the partial equation

- 8 = 10 + c ⇒ c = - 8 - 10 = - 18

y = - x - 18 ← equation of line s

The equation in slope-intercept form is y=-x-18.

The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.

Given that, Line r has an equation of y + 3 = -(x + 2).

y+3=-x+2

y=-x+2-3

y=-x-1

Here, slope m=-1

Line s includes the point (-10, -8) and is parallel to line r.

The slope of a line parallel to given line is m1=m2

Substitute m=-1 and (x, y)=(-10, -8) in y=mx+c, we get

-8=-1(-10)+c

c=-18

So, the equation is y=-x-18

Therefore, the equation in slope-intercept form is y=-x-18.

The total percent of the design which is floral fabric made in the shape of quilt square is 13.73%.

Area of square is the square of its sides length. It can be given as,

\(A=a^2\)

Here, (a) is the length of the side of the square.

This figure represents a design that is sewn onto a quilt square. The semicircles are a solid green fabric and the square is a floral fabric.

The area of the solid green fabric is 8π square inches. There are total 8 semicircles made by the solid green fabric. Thus the area of the one semicircle is,

\(A=\dfrac{8\pi}{4}\\A=2\pi\)

The area of the semicircle is half of πr², where r is the radius of the circle. Therefore,

\(A=\dfrac{\pi r^2}{2}\\2\pi=\dfrac{\pi r^2}{2}\\4=r^2\\r=2\)

This radius of the semicircle is equal to the side of the square. Thus, the area of the side square made with floral fabric is,

\(A=2^2\\A=4\rm\; in^2\)

Thus, the percent  floral fabric in the design is,

\(p=\dfrac{4}{8\pi+4}\times100\\p=\dfrac{4}{8\times3.14+4}\times100\\p=13.73\%\)

Thus the total percent of the design which is floral fabric made in the shape of quilt square is 13.73%.

Since the columns of F(t) are linearly independent and span the solution space of the ODE x' = Ax, we can affirm that they form a fundamental set of solutions to the ODE.

To show that the columns of the matrix-valued function F(t) form a fundamental set of solutions to the ODE x' = Ax, where A is an n x n matrix, we need to demonstrate two properties: linear independence and span.

1. Linear Independence:

We need to show that the columns of F(t) are linearly independent. Let's assume that there exist coefficients c1, c2, ..., cn such that the linear combination c1F1(t) + c2F2(t) + ... + cnFn(t) = 0, where Fi(t) represents the ith column of F(t).

Now, considering the ODE x' = Ax, we can rewrite it as:

x' = F'(t)x

Since F(t) is nonsingular for all t, its columns are linearly independent. Therefore, the only solution to the equation c1F1(t) + c2F2(t) + ... + cnFn(t) = 0 is when c1 = c2 = ... = cn = 0. This proves that the columns of F(t) are linearly independent.

2. Span:

We need to show that the columns of F(t) span the solution space of the ODE. Let x(t) be a solution to the ODE x' = Ax. We can write x(t) as a linear combination of the columns of F(t):

x(t) = c1F1(t) + c2F2(t) + ... + cnFn(t)

Taking the derivative of both sides, we have:

x'(t) = c1F1'(t) + c2F2'(t) + ... + cnFn'(t)

Since F(t) satisfies the ODE x' = Ax, we have:

x'(t) = F'(t)x(t) = (F'(t))(c1F1(t) + c2F2(t) + ... + cnFn(t))

Expanding the right-hand side, we obtain:

x'(t) = c1(F'(t)F1(t)) + c2(F'(t)F2(t)) + ... + cn(F'(t)Fn(t))

Notice that F'(t)Fj(t) represents the jth column of F'(t) (the derivative of F(t)).

Therefore, we have shown that x'(t) can be expressed as a linear combination of the columns of F'(t), which implies that x(t) can be expressed as a linear combination of the columns of F(t). Thus, the columns of F(t) span the solution space of the ODE.

In conclusion, since the columns of F(t) are linearly independent and span the solution space of the ODE x' = Ax, we can affirm that they form a fundamental set of solutions to the ODE.
