Answer:

(c)

Step-by-step explanation:

Answer is (c) 2

Its my guess

The inverse of (- 2 . 3 ) is (1 / - 2.3 ).

In mathematics, the inverse of a number refers to the concept of taking its reciprocal; for instance (2 . w ) results in its reciprocal as ( 1/ 2. w ). When a number is multiplied by its inverse the result yields 1, meaning that the product of the number and its inverse, i.e. reciprocal always equals 1.

As per the given number which is (-2.3) and its inverse is ( 1 / -2.3 ), when these two numbers are multiplied together they result in 1. Such as:

(-2.3) x ( 1 / -2.3 ) = 1

2/3 + 1/4

Get a common denominator of 12

2/3 *4/4   + 1/4 *3/3

8/12 + 3/12

11/12

Explanation

Add the components of the vectors

u+v = (4,2) + (-3,2)

u+v = (4+(-3),  2+2)

u+v = (1,4)

Then to evaluate the length of vector u = (a,b), we use this formula

|u| = sqrt(a^2+b^2)

Which is derived from the pythagorean theorem. We're looking for the hypotenuse of the right triangle formed. In this case a = 1 and b = 4.

So,

|u+v| = sqrt(1^2 + 4^2)

|u+v| = sqrt(17)

Step-by-step explanation:

The surface area of the new prism is 702 square inches.

Given that,

The area of triangular prism = 78 square inches

Use the fact that the surface area of a similar prism is proportional to the square of the scale factor.

Since,

The new prism is 3 times larger than the original, the scale factor is 3.

Therefore,

The surface area of the new prism will be 3 = 9 times larger than the original prism.

To find the surface area of the new prism, we can multiply the surface area of the original prism by 9,

78 in x 9 = 702 in²

Thus,

Surface area of new prism =  702 in².

The correct description that defines the prism square is option B: "Is another hand instrument that is also used to determine or set out right angles."

A prism square is a tool used in construction and woodworking to establish or verify right angles. It consists of a triangular-shaped body with a 90-degree angle and two perpendicular sides. The edges of the prism square are straight and typically have measurement markings. It is commonly used in carpentry, masonry, and other trades where precise right angles are essential for accurate and square construction. Option A describes a different tool involving mirrors set at an angle, which is not related to the prism square.

In the posttest control group design shown above, selection bias is eliminated by randomization.

Randomization is the best way to eliminate the effects of selection bias. The posttest control group design is an experimental design that entails the random selection of study participants into two groups: a control group that is not subjected to the intervention and a treatment group that receives the intervention. Following that, measurements are taken from the two groups. One of the benefits of the posttest control group design is that it eliminates the possibility of selection bias and assures the internal validity of the study.The aim of randomization is to ensure that study participants are chosen entirely at random and that the researcher does not have any impact on the selection process. As a result, this technique is used to guarantee that the two groups are equivalent at the beginning of the study in terms of variables that could affect the outcome. This technique eliminates the effect of selection bias on the study results.Therefore, in the posttest control group design shown above, selection bias is eliminated by randomization.

Given differential equation is

y⁽⁴⁾ + 2y⁺² + y

= 3 + cos 3t

To find the general solution of the differential equation, we have to find the characteristic equation by finding the auxiliary equation Let m be the auxiliary equation; The auxiliary equation is:

m⁴ + 2m² + 1 = 0

This auxiliary equation is a quadratic in form of a quadratic, we can make the substitution z = m² and get the equation z² + 2z + 1 = (z + 1)² = 0.

The quadratic has a double root of -1. Then the auxiliary equation becomes m² = -1,  m = ±I. The general solution for the differential equation isy

\((t) = c₁ sin(3t) + c₂ cos(3t) + c₃ sinh(t) + c₄ cos(t) + 1/3 (cos 3t)\)

where c₁, c₂, c₃ and c₄ are arbitrary constants. Therefore, the general solution of the given differential equation is

\(y(t) = c₁ sin(3t) + c₂ cos(3t) + c₃ sinh(t) + c₄ cosh(t) + 1/3 cos(3t) .\)

The area of the regular decagon is approximately 98.7 square meters when rounded to the nearest tenth.

To find the area of a regular decagon, we can use the formula:

Area = (1/2) * apothem * perimeter

Given that the apothem is 5 meters and the side length is 3.25 meters, we can calculate the perimeter using the formula for a regular decagon:

Perimeter = 10 * side length

Perimeter = 10 * 3.25 = 32.5 meters

Substituting the values into the area formula, we get:

Area = (1/2) * 5 * 32.5

Area = 2.5 * 32.5 = 81.25 square meters

Rounding to the nearest tenth, the area of the regular decagon is approximately 98.7 square meters.

Therefore, the area of the regular decagon with an apothem of 5 meters and a side length of 3.25 meters is approximately 98.7 square meters when rounded to the nearest tenth.

Answer:

We can start by isolating the variable "h".

5 8 h + 1 1 2 = 5

Subtracting 11/2 from both sides:

5 8 h = 5 - 1 1 2

Simplifying:

5 8 h = 8 1 2

Dividing both sides by 5/8:

h = 8 1 2 ÷ 5 8

Converting the mixed number to an improper fraction:

h = (8 x 8 + 1) ÷ 5 8

h = 65/8

Now, we can convert this fraction to a mixed number:

h = 8 1/8

Brigid has already picked for 8 1/8 hours, so the amount of time needed to pick the remaining strawberries is:

5 - (1 1/2 + 5/8 x 8) = 5 - (3 5/8) = 1 3/8

Therefore, Brigid still needs to pick for 1 3/8 hours to fill 5 bushels of strawberries. The answer is 1 and 3/8 hours or 2 and 3/16 hours (if simplified).

Step-by-step explanation:

a) Value of the test statistic is 1.54.

b) Range for the p-value is: 0.050 < p-value < 0.100

c) Do not reject H0. Due to insufficient evidence to get a result that μ > 12.

d) Do not reject H0. Due to insufficient evidence to get a result that μ > 12.

(a) To compute the value of the test statistic, we use the formula:

t = (x - μ) / (s / √n)

where;

x is sample mean

μ is hypothesized population mean

s is sample standard deviation

n is sample size.

Plugging in the given values, we get:

t = (14 - 12) / (4.54 / √25) ≈ 1.54

So the value of the test statistic is 1.54.

(b) To compute the p-value, we need to find the area under the t-distribution curve to the right of the test statistic. Using a t-table with 24 degrees of freedom (df = n - 1 = 25 - 1 = 24), we find that the closest value to 1.54 is 1.711.

The area to the right of 1.711 is between 0.05 and 0.10, so the range for the p-value is:

0.050 < p-value < 0.100

(c) At α = 0.05, the p-value (0.050 < p-value < 0.100) is greater than α, so we do not reject the null hypothesis. The conclusion is:

Do not reject H0. Due to insufficient evidence to get a result that μ > 12.

(d) The rejection rule by using of the critical value is:

If t ≤ tα,df, reject H0.

If t > tα,df, do not reject H0.

At α = 0.05 and df = 24, the critical value (from a t-table) is 1.711. Since the calculated test statistic (1.54) is less than the critical value (1.711), we do not reject the null hypothesis. The conclusion is the same as in part (c):

Do not reject H0. Due to insufficient evidence to get a result that μ > 12.

Σ \(x^{2} p(x)\) = 19.6436
