Supposed charity received a donation of $23.9 million. If this represents 54% of the charity donated funds what is the total amo

Tanzania [10]

Total amount of funds is $44.26 million.

Step-by-step explanation:

Given,

Donation received = $23.9 million

As it represents 54% of charity.

Let,

Total amount = x

Therefore,

54% of x = 23.9 million

$\frac{54}{100}*x=23.9\\0.54x=23.9$

Dividing both sides by 0.54

$\frac{0.54x}{0.54}=\frac{23.9}{0.54}\\x=\$44.26\ millions$

Total amount of funds is $44.26 million.

30 POINTS!!! What is the value of a? 27.5 45 50 90

Talja [164]

Using opposite outside angle on a circle is the inside angle times 2.

A is opposite the inside angle of 45, so a = 45 x 2 = 90 degrees.

Bernoulli differential equation... y'+xy=xy^2

snow_lady [41]

$y'+xy=xy^2\implies y^{-2}y'+xy^{-1}=x$

Let $z=y^{-1}$ , so that $z'=-y^{-2}y'$ . Then the ODE becomes linear in $z$ with

$-z'+xz=x\implies z'-xz=-x$

Find an integrating factor:

$\mu(x)=\exp\left(\displaystyle\int-x\,\mathrm dx\right)=e^{-x^2/2}$

Multiply both sides of the ODE by $\mu$ :

$e^{-x^2/2}z'-xe^{-x^2/2}z=-xe^{-x^2/2}$

The left side can be consolidated as a derivative:

$\left(e^{-x^2/2}z\right)'=-xe^{-x^2/2}$

Integrate both sides with respect to $x$ to get

$e^{-x^2/2}z=e^{x^2/2}+C$

where the right side can be computed with a simple substitution. Then

$z=1+Ce^{x^2/2}$

Back-substitute to solve for $y$ .

$y^{-1}=1+Ce^{x^2/2}\implies y=\dfrac1{1+Ce^{x^2/2}}$

A normal distribution has a mean of 186.4 and a standard deviation of 48.9. What percent of data will be greater than 235.3?

gayaneshka [121]

Answer:

15.9% of the data will be greater than 235.3.

Step-by-step explanation:

Use a calculator with statistical functions. In this case you'll need the cumulative normal distribution: normcdf(.

Evaluate the following: normcdf(235.3, 10000,186.4, 48.9):

We get: 0.159, or 15.9%

15.9% of the data will be greater than 235.3.
