One can convert temperature from Fahrenheit into Newton using the formula N=11/60(F-32) . What is the temperature in Fahrenheit

corresponding to N degrees Newton?

N=11/60*(F-32). Multiply both sides by 60/11, so that 60/11*N=F-32. Add both sides by 32, F=60/11*N+32.

Sari applied the distributive property using the greatest common factor to determine the expression that is equivalent to 84 + 4

kykrilka [37]

Expression: 84 + 40

Here, Greatest Common Factor (GCF) of 84 & 40 is 4, so take it as a common factor:

= 4(21 + 10)

In short, Your Final Expression would be: 4(21 + 10)

Hope this helps!

Kryger [21]

A passenger flies on a heading of N40W with an airspeed of 240 km/h. His actual ground velocity is 250 km/h at a bearing of N60E. the speed and direction of the wind are V=245.15kw/h at N83.46E. This is further explained below.

<h3>What is the speed and direction of the wind.?</h3>

Generally, the equation for the cosine rule is mathematically given as

a2 = b2 + c2 – 2bc cos ∠x.

Therefore

V^2 = (240^2 + 250^2) – (2(240*250)* cos 100)

V^2=140937.7813

V=375.42kw/h

In conclusion, the sine rule is mathematically given as

Sin x/240=sin60/375.42kw/h

Therefore

sin x=sin100*250/375.42kw/h

x=40.981

Hence

$\theta= 180-2*48.27$

Direction N83.46E

The annual precipitation amounts in a certain mountain range are normally distributed with a mean of 104 inches, and a standard

dsp73

Answer:

91.92% probability that the mean annual precipitation during 49 randomly picked years will be less than 106.8 inches

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal probability distribution:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Central limit theorem:

The Central Limit Theorem estabilishes that, for a random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sample means with size n of at least 30 can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$

In this problem, we have that:

$\mu = 104, \sigma = 14, n = 49, s = \frac{14}{\sqrt{49}} = 2$

What is the probability that the mean annual precipitation during 49 randomly picked years will be less than 106.8 inches

This is the pvalue of Z when X = 106.8. So

$Z = \frac{X - \mu}{\sigma}$

By the Central Limit Theorem

$Z = \frac{X - \mu}{s}$

$Z = \frac{106.8 - 104}{2}$

$Z = 1.4$

$Z = 1.4$ has a pvalue of 0.9192

0.9192 = 91.92% probability that the mean annual precipitation during 49 randomly picked years will be less than 106.8 inches
