Answer:x=x=

−2

Step-by-step explanation:

Let's solve for x.

2y+5x=4

Step 1: Add -2y to both sides.

5x+2y+−2y=4+−2y

5x=−2y+4

Step 2: Divide both sides by 5.

−2y+4

−2

Write the standard form of the line that contains a slope -3/8 and passes through the point (5, -4).

Kipish [7]

Answer:

y+3/8x=-17/8

Step-by-step explanation:

y=mx+b

y=-3/8x+b

-4=-3/8(5)+b

-4=-15/8+b

-32/8+15/8=b

-17/8=b

y=-3/8x-17/8

change to standard form where x and y are on one side of the equation

y+3/8x=-17/8

Answer:

The formula for a quadrilateral depends on the shape.

Area of a Parallelogram: Base × Height

Area of a Rectangle: Length × Breadth

Area of a Square: (side)^2

Area of a Kite: (1 ⁄ 2) × Product of Diagonals

Area of a Trapezoid: (base1+base2/2) x Height

I hope this helps :)

Over what interval is the function differentiable? Y=3/2(x-1)

jolli1 [7]

Answer-

The interval where the function is diffrentiable is

$[-\infty,1)\ \bigcup\ (1,\infty]$

Solution-

The given expression is,

$y=\dfrac{3}{2(x-1)}$

The function will be differentiable where it is continuous and it will not be differentiable, where the function is not continuous.

The function continuous everywhere except at x = 1, because

$\Rightarrow 2(x-1)=0\\\\\Rightarrow x-1=0\\\\\Rightarrow x=1$

at x = 1, its limit does not exist.

Therefore, apart from x=1, this function is differentiable everywhere. The interval will be

$[-\infty,1)\ \bigcup\ (1,\infty]$

A survey of 25 randomly selected customers found the ages shown (in years). The mean is 32.64 years and the standard deviation i

____ [38]

Answer:

See below for answers and explanations

Step-by-step explanation:

Part A

Assuming that conditions have been met for the interval, we use the formula $\displaystyle CI=\bar{x}\pm t\frac{s}{\sqrt{n}}$ where $\bar{x}$ represents the sample mean, $t$ represents the critical value, $s$ represents the sample standard deviation, and $n$ is the sample size.

The critical value of $t$ for an 80% confidence level with degrees of freedom $df=n-1=25-1=24$ is equivalent to $t=1.317836$

Thus, we can compute the confidence interval:

$\displaystyle CI=\bar{x}\pm t\frac{s}{\sqrt{n}}\\\\CI=32.64\pm1.317836\biggr(\frac{9.39}{\sqrt{25}}\biggr)\\\\CI\approx\{30.17,35.11\}$

Therefore, we are 80% confident that the true mean age of all customers is between 30.17 and 35.11 years.

Part B

The margin of error is $\displaystyle t\frac{s}{\sqrt{n}}=1.317836\biggr(\frac{9.39}{\sqrt{25}}\biggr)\approx2.47$
