Delaney  solve for X by isolating it,  or getting it by it self

Step-by-step explanation:

5x−2(x+1)=1/4 (distribute the 2)

5x-2x - 2 = 1/4  (subtract 2x from 5x)

3x -2 +2 = 1/4 +2 (add 2 to both sides)

3x = 2_1/4  (put 2 &  1/4 together)

3x = 9/4 (convert 2_1/4 to  9/4)

\(\frac{1}{3}\)*3*x =  \(\frac{1}{3}\)*\(\frac{9}{4}\)  ( mutilply both sides by  1/3)

X = 3/4   (cross multiply )

There you go

X = \(\frac{3}{4}\)

Answer:

\(\huge\boxed{\bf\:x = \frac{3}{4}}\)

Step-by-step explanation:

\(5x - 2(x+1)=\frac{1}{4}\)

Use the distributive property for 2(x + 1).

\(5x - 2x - 2= \frac{1}{4}\)

Subtract 2x from 5x.

\(3x - 2= \frac{1}{4}\)

Bring 2 to the right hand side of the equation .

\(3x = \frac{1}{4} + 2\)

Add 1/4 & 2.

\(3x = \frac{1}{4} + \frac{8}{4} \: \: [LCM = 4]\\3x = \frac{9}{4}\)

Now, bring 3 to the right hand side of the equation .

\(x = \frac{9}{4} \times \frac{1}{3}\\x = \frac{9}{12}\\\boxed{\bf\:x = \frac{3}{4}}\)

The time taken to reach the maximum height is 1.25 seconds.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that a ball is thrown into the air with an upward velocity of 40ft/s. Its height h in feet after t seconds is given by the function h(t) = -16t² + 40t + 10.

To calculate the time to get the maximum height to differentiate the function with respect to t and equate it with zero,

h(t) = -16t² + 40t + 10.

(d/dt)h(t) = ( d / dt ) { -16t² + 40t + 10 } = 0

( d / dt ) { -16t² + 40t + 10 } = 0

-32t  + 40 = 0

-32t = -40

t = 40 / 32

t = 1.25 seconds

The results are different from each other because the confidence interval limits and the mean values differ.

The confidence interval is a range of values within which we estimate the true population mean to lie. In the first set of data, with n = 220, x = 29.9 hg, and s = 7.3 hg,

we construct a 98% confidence interval estimate of the mean. With these values, the confidence interval would be calculated using the formula:

CI = x ± (Z * (s / √n))

where Z is the critical value corresponding to the desired confidence level. For a 98% confidence level, Z would be the value corresponding to the middle 98% of the standard normal distribution, which is approximately 2.33.

Plugging in the values, we get:

CI = 29.9 ± (2.33 * (7.3 / √220))

CI = 29.9 ± 2.033

Therefore, the confidence interval estimate of the mean for the first set of data is approximately 27.9 to 32.9 hg.

In the second set of data, with only 16 sample values, x = 29.7 hg, and s = 3.1 hg, we have a different confidence interval. Following the same formula and using a critical value of 2.33, we get:

CI = 29.7 ± (2.33 * (3.1 / √16))

CI = 29.7 ± 1.854

So, the confidence interval estimate of the mean for the second set of data is approximately 27.8 to 31.6 hg.

Comparing the two confidence intervals, we can see that they have different limits and do not overlap.

Therefore, the results between the two confidence intervals are different. The correct option is C. Yes, because one confidence interval does not contain the mean of the other confidence interval.

The equation of the line is y = -(3/4)x - 6.

A line is a perfectly straight, one-dimensional shape that extends endlessly in both directions and has no thickness.

Given that, the line passes through the points (-4,-3) and has a slope of -3/4.

The equation of the line in point-slope form is:

y - y₁= m (x -x ₁)

Substitute (x₁,y₁) = (-4,-3) and m = -3/4 into the above equation,

y - (-3) = -3/4 (x - (-4))

y + 3 = -3/4 (x + 4)

y = -(3/4)x -3 -3

The selling price per unit under the variable cost method is $53.25

To calculate the selling price per unit under the variable cost method, we need to add up all the variable costs and then add a markup for the target profit.

Variable cost per unit = Direct materials + Direct labor + Variable overhead + Variable selling, general, and administrative costs

Variable cost per unit = $17.50 + $11.00 + $12.00 + $9.50

Variable cost per unit = $50.00

Now we need to add a markup for the target profit:

Target profit per unit = Target profit / Number of units

Target profit per unit = $65,000 / 20,000

Target profit per unit = $3.25

Selling price per unit under the variable cost method = Variable cost per unit + Target profit per unit

Selling price per unit under the variable cost method = $50.00 + $3.25

Selling price per unit under the variable cost method = $53.25

Step-by-step explanation:

Answer:

see explanation

Step-by-step explanation:

Using the identity

sin²x + cos²x  = 1 then

sin²x = 1 - cos²x

sin x = ± \(\sqrt{1-cos^2x}\)

Given cos θ = \(\frac{2}{3}\) , then

sinθ = ± \(\sqrt{1-(\frac{2}{3})^2 }\) = ± \(\sqrt{1-\frac{4}{9} }\) = ± \(\sqrt{\frac{5}{9} }\) = ± \(\frac{\sqrt{5} }{3}\)

Also

tanθ = \(\frac{sin0}{cos0}\)

       = \(\frac{\frac{\sqrt{5} }{3} }{\frac{2}{3} }\)

(a) The graph of the parabola that opens down, with a vertex of (2, 9), and passing through the points (0, 5), (–1, 0), and (–2, –7) can be plotted using symmetry.
(b) The values for h and k in the equation f(x) = a(x - h)^2 + k are h = 2 and k = 9.
(c) If a is equal to -1, the equation of the parabola is f(x) = -(x - 2)^2 + 9.

(a) To graph the parabola, we can plot the given points (0, 5), (–1, 0), and (–2, –7), and then determine three additional points on the other side of the parabola using symmetry. Since the vertex is (2, 9), we can reflect the plotted points across the vertical line passing through the vertex to get corresponding points on the other side.
(b) The equation of a parabola in the vertex form is f(x) = a(x – h)^2 + k, where (h, k) represents the vertex. In this case, the given vertex is (2, 9), so h = 2 and k = 9.
(c) If a is equal to -1, we substitute the values of a, h, and k into the vertex form equation. Thus, the equation of the graphed parabola becomes f(x) = -(x – 2)^2 + 9.

b) A can of soup = x = $2.09

Loaf of bread = y = $1.35

Step-by-step explanation:

A grocery store is offering a sale on bread and soup. Khalil buys four cans of soup and three

loaves of bread for $11.67. Ronda buys eight cans of soup and one loaf of bread for $12.89.

Homework Help!

Let us represent:

a can of soup = x

Loaf of bread = y

a. Write equations for both Khalil's and Ronda's purchases.

For Khalil's purchase

= Khalil buys four cans of soup and three loaves of bread for $11.67.

4x + 3y = 11.67.....Equation 1

Ronda buys eight cans of soup and one loaf of bread for $12.89.

8x + y = 12.89......Equation 2

b. Solve the system to find the price of one can of soup and the price of one loaf of bread.

We have:

4x + 3y = 11.67.....Equation 1

8x + y = 12.89......Equation 2

y = 12.89 - 8x

We substitute 12.89 - 8x for y in Equation 1

4x + 3(12.89 - 8x) = 11.67

4x + 38.67 - 24x = 11.67

38.67 - 11.67 = 24x - 4x

27 = 20x

x = 27/20

x = 1.35

y = 12.89 - 8x

y = 12.89 - 8 × 1.35

y = 12.89 - 10.8

y = 2.09

Therefore,

Solving for y

a can of soup = x = $2.09

Loaf of bread = y = $1.35

The correct statement is d. a measure of the total kinetic energy and potential energy of the particles of a substance.

The energy present in a system that determines its temperature is referred to as thermal energy. Thermal energy flows as heat. Thermodynamics is a whole field of physics that studies how heat is transmitted between various systems and how work is performed in the process (see the first law of thermodynamics).

Thermal energy refers to the total kinetic energy and potential energy possessed by the particles (atoms or molecules) within a substance. It is a measure of the overall energy content of the substance, taking into account the motion and interactions of its particles. The thermal energy of a substance is influenced by its temperature, as temperature is a measure of the average kinetic energy of the particles. However, thermal energy also includes the potential energy associated with the arrangement and interactions of the particles within the substance.

Therefore, the correct statement is d. a measure of the total kinetic energy and potential energy of the particles of a substance.

A binomial experiment is defined as an experiment that satisfies the following four conditions: 1) the experiment consists of a fixed number of independent trials, 2) each trial has only two possible outcomes, which we call success and failure, 3) the probability of success is constant across all trials, and 4) the trials are independent of each other. Given these conditions, the number of successes in a binomial experiment is the count of the trials that resulted in a success outcome.  Therefore, the statement is true.

Answer: Karl is 16 years old.

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

We are to solve for time using compound interest formulas

For Hailey

Principal = $200

Amount = Double of Principal = $4000

Rate = 2 3/8% = 2.375.

Time = ?

Hence,

First, convert R as a percent to r as a decimal

r = R/100

r = 2.375/100

r = 0.02375 per year,

Then, solve the equation for t

t = ln(A/P) / r

t = ln(4,000.00/2,000.00) / 0.02375

t = 29.185 years

≈ 29.19 years

For Sophie

Principal = $200

Amount = Double of Principal = $4000

Rate = 2 7/8% = 2.875

Time = ?

First, convert R as a percent to r as a decimal

r = R/100

r = 2.875/100

r = 0.02875 per year,

Then, solve the equation for t

t = ln(A/P) / n[ln(1 + r/n)]

t = ln(4,000.00/2,000.00) / ( 365 × [ln(1 + 0.02875/365)] )

t = ln(4,000.00/2,000.00) / ( 365 × [ln(1 + 7.8767E-5)] )

t = 24.11 years

How much longer would it take for Hailey's money to double than for Sophie's money to double?

For Hailey it takes 29.19 years

For Sophie it takes 24.11 years

We find the difference

Therefore, it would take 5.08 years for Hailey's money to double than Sophie

Using the system of inequalities y ≥ 0, x ≥ 0, y ≤ -2x + 4 the minimum value of f(x,y) = 3x + y for the feasible region is d) 0.

We need to find the minimum value of the function

f(x,y) = 3x + y

we can use Lagrange multipliers method defining

F(x,y) = f(x,y) - λx g(x,y)  , where g(x,y) = x²+36 x y² - 1, such that

Fx(x,y) = fx(x,y) - λx gx(x,y) = 0

Fy(x,y) = fy(x,y) - λx gy(x,y) = 0

g(x,y)=0

where the sub-indices x and y represent the partial derivatives with respect to x and y, then

fx(x,y) - λx gx(x,y) = 3 - λx(2x) = 0 → x =3/(2xλ)

fy(x,y) - λx gy(x,y) = 1 - λx(36x2xy) = 0 → y =1/(72xλ)

x²+36xy² - 1 = 0 → [3/(2xλ)]²+36*[1/(72xλ)]² - 1 = 0

therefore, Using the system of inequalities y ≥ 0, x ≥ 0, y ≤ -2x + 4 the minimum value of f(x,y) = 3x + y for the feasible region is d) 0.
