Answer: Equation: E= 20H

Earning's after 15 hours: E= 20(15)

E = 300

Step-by-step explanation:

The equation would be E =20H. E means her total earnings. 20 is how much money she earns per hour. H is how many hours she tutors. If you put it all together, you get E = 20H.

To solve how much she would get for 15 hours, plug in 15 for H so E=20(15). 20 x 15 = 300. Therefore, she will get $300 after teaching for 15 hours.

PRETTY PLEASE HELP ME! this is 4 a test and i’m rlly struggling :/

igor_vitrenko [27]

Alright here we go
First we need to find the upper angle by doing 180 - 143 = 37. Because it’s a straight line.
Second we need to find angle ADC
a triangle has 180 degrees, and we have 38 and 37.
180 - (38+37) = 105
then we find what the question wants:
180 - 105 = 75 degrees

D/dx 3^x= <br>Find the derivative <br>

gregori [183]

Differentiate using the exponential rule, which determines that $\bf{\frac{d}{dx}[a^{x}] }$ is $\bf{a^{x} \ In(a) }$ when a=3.

$\boldsymbol{ 3^{x} \ In(3) \ \to \ \ \ Answer }$

Therefore, the correct option is "E". You just have to remove the parentheses.

$\red{\boxed{\green{\boxed{\boldsymbol{\purple{Pisces04}}}}}}$

A regular six-sided die is rolled 1000 times. Use the binomial distribution to determine the standard deviation for the number o

ANTONII [103]

The standard deviation for the number of times an odd number is rolled is 15.8

<h3>How to determine the standard deviation?</h3>

The given parameters are:

Die = regular six-sided die

n = 1000

The probability of rolling an odd number is:

p = 1/2 = 0.5

The standard deviation is then calculated as;

$\sigma = \sqrt{np(1 - p)$

This gives

$\sigma = \sqrt{1000 * 0.5 * (1 - 0.5)$

Evaluate the products

$\sigma = \sqrt{250$

Evaluate the root

$\sigma = 15.8$

Hence, the standard deviation is 15.8

What is the third term when -2h4+5h2-3-2h-8h3 is arranged in descending order

Oduvanchick [21]

The third term would be 5h2 because the descending order would be
-2h4 - 8h3 + 5h2 - 2h - 3
