Find the difference ( 9/4​x+6) − (− 5/4​x−24)=​

Answers

Answer:

[tex]=\frac{7}{2}x+30[/tex]

Step-by-step explanation:

So we have the equation:

[tex](\frac{9}{4}x+6)-(-\frac{5}{4}x-24})[/tex]

First, distribute the negative on the right:

[tex]=(\frac{9}{4}x+6)+(\frac{5}{4}x+24})[/tex]

Combine like terms:

[tex]=(\frac{9}{4}x+\frac{5}{4}x})+(6+24)[/tex]

Add:

[tex]=\frac{14}{4}x+30[/tex]

We can reduce our fraction by dividing both layers by 2. Thus:

[tex]=\frac{7}{2}x+30[/tex]

So this would be our answer :)

Last year a banquet hall charged $65 per person to attend a function. The function C(p) = 65p represents the total cost, C, to rent the hall based on the number of people, p, that would attend the event. If the hall can hold a total of 50 people, what is the domain and range for this function?

Answers

Answer:

Domain = [0, 50]

Range   = [0, 3250]

Step-by-step explanation:

A function shows the relationship between two variables (independent variable and dependent variable). The independent variable is a variable not dependent on any variable, it is the input of the function while the dependent variable is a variable dependent on other variable, it is the output of the function.

The domain of a function is the set of all input variables (independent variable) and the range of a function is the set of all output variables (dependent variables).

In the function C(p) = 65p, p is the independent variable and C(p) is the dependent variable.

Since the hall can hold a total of 50 people, the domain of the function = [0, 50]

C(0) = 65(0) = 0, C(50) = 65(50) = 3250

Hence, the range of the function = [0, 3250]

Test at the 0.1 significance level.Identify the correct alternative hypothesis:p=21.21p=21.21μ>21.21μ>21.21μ=21.21μ=21.21μ<21.21μ<21.21p<21.21p<21.21p>21.21p>21.21

Answers

Answer:

Null hypothesis:

[tex]\mathtt{H_o : \mu = 21.21}[/tex]

Alternative hypothesis

[tex]\mathtt{H_1 : \mu \geq 21.21}[/tex]

t = -0.080

Decision Rule: To  reject the null hypothesis if t > 1.340 at t

Since t = -0.080, this implies that t < 1.340 that means the t statistics value did not fall into the rejection region. Hence, we fail to reject the null hypothesis at the level of significance 0.10

Conclusion: We conclude that there is insufficient evidence to support the claim that the mean nickel diameter drawn by children in the low-income group is greater than 21.21 mm.

Step-by-step explanation:

Given that:

the sample mean [tex]\overline x[/tex] = 21.15

the standard deviation [tex]\sigma[/tex] = 4.7512

sample size N = 40

The objective is to test the claim that the mean nickel diameter drawn by children in the low-income group is greater than 21.21 mm.

At the level of significance of 0.1

The null hypothesis and the alternative hypothesis for this study can be computed as follows:

Null hypothesis:

[tex]\mathtt{H_o : \mu = 21.21}[/tex]

Alternative hypothesis

[tex]\mathtt{H_1 : \mu \geq 21.21}[/tex]

This test signifies a one-tailed test since the alternative is greater than or equal to 21.21

The t-test statistics can be computed by using the formula:

[tex]t= \dfrac{\overline x - \mu }{\dfrac{\sigma}{\sqrt{n}}}[/tex]

[tex]t = \dfrac{21.15- 21.21 }{\dfrac{4.7152}{\sqrt{40}}}[/tex]

[tex]t = \dfrac{-0.06 }{\dfrac{4.7152}{6.3246}}[/tex]

t = -0.080

degree of freedom = n - 1

degree of freedom =  40 - 1

degree of freedom = 39

From the t statistical tables,

at the level of significance ∝ = 0.1 and degree of freedom df = 39, the critical value of [tex]\mathtt{{T_{39,0.10} = 1.304}}[/tex]

Decision Rule: To  reject the null hypothesis if t > 1.340 at t

Since t = -0.080, this implies that t < 1.340 that means the t statistics value did not fall into the rejection region. Hence, we fail to reject the null hypothesis at the level of significance 0.10

Conclusion: We conclude that there is insufficient evidence to support the claim that the mean nickel diameter drawn by children in the low-income group is greater than 21.21 mm.

What is line?

A simple line in Euclidean geometry. A line, according to Euclid, is the distance between two points and can stretch forever in either direction. While Euclid's initial definition is now regarded as a line segment, such an extension in both directions is now thought of as a line.

Given:

The lines y and l are given in the graph,

The equation of the line y can be written as shown below,

y = x + c

x = c  (as the y coordinate of the y-axis is zero)

The equation of the line shifted 4 units to the right can be represented as

y = mx + c

Here, the slope is 1 and the intercept is -4 so,

x = 4

Thus, the line l is x = 4.

The area of the base is 1·/4ft^2 . What is the volume of the cube?

Answers

Answer:

1/8 ft^3

Step-by-step explanation:

The cube has equal sides. So u square root the base area and u get 1/2 ft. The length, width and height are all 1/2. So u cube the 1/2. Your final answer would be 1/8 ft^3.

Answer:

V = 1/8 ft³

Step-by-step explanation:

Area of the base = 1/4 ft² = l²

l² = 1/(2)² ft²

l = 1/2 ft

V = l³

= (1/2 ft)³

= 1/2³ ft³

3. What are the coordinates of the

centroid of a triangle with vertices at

Q (1,0), R (-10,-6), and S (0, -6)?

Answers

Answer:

coordinates for the centroid is at (-3, -4)

Step-by-step explanation:

The centroid of a triangle is simply defined as the center point which is equidistant from the three vertices.

Let's denote the centroid as O. Thus, the coordinates of O will be: (O_x, O_y).

Now, the formula to calculate the centroid of a triangle with coordinates (O_x, O_y) is given by;

For x - coordinate;

O_x = (A_x + B_x + C_x)/3

For y - coordinate;

O_y = (A_y + B_y + C_y)/3

From the question,

A_x = 1

B_x = -10

C_x = 0

A_y = 0

B_y = -6

C_y = -6

Thus;

O_x = (1 - 10 + 0)/3

O_x = -9/3

O_x = -3

Also,

O_y = (0 - 6 - 6)/3

O_y = - 12/3

O_y = - 4

Thus, coordinates for the centroid is at (-3, -4)

Let X be a random variable with CDF given byFX(t) =0 for t < 1,1 /2 for ?1 t < 11/ 2 t for 1 t < 21 for t 2Calculate E[X]

Answers

Answer:

[tex]\mathbf{E(X) = \dfrac{3}{4}}[/tex]

Step-by-step explanation:

From the given data, the cumulative distribution function of a random variable can be represented as:

[tex]F_X(t) =\left\{ \begin{array}{c}0........... t <-1 \\ \dfrac{1}{2} ... -1 \leq t < 1\\ \dfrac{1}{2} ....... 1 \leq t < 2 \\ 1 .............. t \geq 2\\\end{array}\right.[/tex]

The objective is to estimate E(X), to do that, let's first evaluate the probability density function by differentiating the cumulative distribution function from above.

[tex]f_X(x) =\left \{ {{\dfrac{1}{2} .......1 \leq x \leq 2 } \atop {0..... otherwise }} \right.[/tex]

[tex]f_X(t) =\left\{ \begin{array}{c} \dfrac{d}{dx}(0)=0........... <-1 \\ \dfrac{d}{dx}(\dfrac{1}{2} ) =0... -1 \leq t < 1\\ \dfrac{d}{dx}(\dfrac{1}{2}x) = \dfrac{1}{2}....... 1 \leq x < 2 \\ \dfrac{d}{dx}(1) = 0 .............. x \geq 2\\\end{array}\right.[/tex]

The expected value of x i

.e E(X) can now be estimated by taking the integral:

[tex]E(X) = \int ^{\infty}_{\infty} x f(x) \ dx[/tex]

[tex]E(X) = \int ^{1}_{- \infty} x 0 dx + \int^2_1 \ x \dfrac{1}{2}\ dx + \int ^{\infty}_2 \ x0dx[/tex]

[tex]E(X) = \int ^{2}_{1} x \dfrac{1}{2} dx[/tex]

[tex]E(X) = \dfrac{1}{2}[\dfrac{x^2}{2}]^2_1[/tex]

[tex]E(X) = \dfrac{1}{2}[\dfrac{4}{2}-\dfrac{1}{2}][/tex]

- For any nonquadrantal angle 0, sin 0 and csc 0 will have the same sign explain why

Answers

Answer:

Because sin 0 and csc 0 establish a relationship where one is reciprocated to the other.

Step-by-step explanation:

Sin 0 is found according to the mathematical expression Sin 0 = y / r.

The csc 0, in turn, is found through the mathematical expression Csc 0 = 1 / sin 0, which is equivalent to y / r.

In both expressions the letter "r" will always be represented by a positive value. This makes Csc 0 and sin 0 have a strong reciprocity and assume the same sign, regardless of the number that represents the "Y". This is because if "y" has a positive value, both sin 0 and csc 0 will have a positive sign, if "Y" will take a negative value, both sin 0 and csc 0 will take negative signs.
