How to convert 25.12% into a fraction of 10,000

scZoUnD [109]

Answer:

25.12/100

Step-by-step explanation:

Percent means per hundred, so 25.12 percent means 25.12 per hundred. Thus, you can make 25.12 the numerator and 100 the denominator, and make 25.12 percent a fraction like this:

At 5:45 p.m., a jet is located 108 mi due east of a city. A second jet is located 214 mi due north of the city. To the nearest t

siniylev [52]

By connecting the distances traveled by the jet and the distance between them, we form a right triangle with hypotenuse equal to the unknown distance.
Using the Pythagorean,
h² = a² + b²
Substituting,
h² = (108 mi)² + (214 mi)²
h = 239.71 miles
Thus, the distance between them is approximately 239.71 miles.

Use demovires theorem to write the complex number in trigonometric form.

Anastasy [175]

$\sqrt3+i=2\left(\dfrac{\sqrt3}2+\dfrac12i\right)$

$\begin{cases}\cos\dfrac\pi6=\dfrac{\sqrt3}2\\\\\sin\dfrac\pi6=\dfrac12\end{cases}$

$\implies\sqrt3+i=2e^{i\pi/6}$

By DeMoivre's theorem,

$(\sqrt3+i)^3=(2e^{i\pi/6})^3=8e^{i\pi/2}=8\left(\cos\dfrac\pi2+i\sin\dfrac\pi2\right)=8i$

Based on a sample of 150 textbooks at the store, you find an average of 70.69 and a standard deviation of 29.6. The point estima

Ugo [173]

Answer:

Step-by-step explanation:

Given that:

The sample size = 150

The sample mean = 70.69

The standard deviation = 29.60

The sample mean is equal to the point estimate of the population = 70.69

At 99% confidence interval level is:

∝ = 1 - 0.99

∝ = 0.01

The critical value:

$Z_{\alpha/2} = Z_{0.01/2} \\ \\ Z_{0.005} = 2.58 \ using \ Z \ tables$

The Margin of error = $Z_{\alpha/2} \times \dfrac{\sigma}{\sqrt{n}}$

$= 2.58 \times \dfrac{29.6}{\sqrt{150}}$

= 2.58 × 2.4168

≅ 6.235

At 99% confidence interval; the estimate of the population mean lies within the interval:

= $\overline x - E < \mu \ < \overline x + E$

= 70.69 - 6.235 < μ < 70.69 + 6.235

= 64.455 < μ < 76.925

= (64.455 , 76.925 )

M² - 5m – 14 = 0

Natasha2012 [34]

Answer:

The answer is m=-2 or m=7.

Step-by-step explanation:

The steps to solve this equation are below:

Factor: to get (m+2)(m−7)=0.

m+2=0 or m−7=0

m=−2 or m=7. So, your answer is m=-2 or m=7.
