Help!!!! giving brainiest!!!

Hi there!

In order to find x, we'll need to create an expression. We know that angle x would be 180 - angle ABC - y. Since we know that angle ABC is equal to 30, we can substitute that in. This gives us 180 - 30 - y. Lastly, we can simplify to get our expression. The expression is 150 - y. The answer is the first option.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

Find an equation of the line that passes through the given points. (Let x be the independent variable and y be the dependent var
lara [203]

Answer:

y=5x-6

Step-by-step explanation:

Hello

let´s see  , we have   P1(3,9) and P2(4.14)

first let's find its slope

m=\frac{y2-y1}{x2-x1}   = \frac{14-9}{4-3}

m=\frac{5}{1} \\m=5

the slope is 5.

y-y_{0} = m(x-x_{0} )\\\\using P1\\\\ y-9 = 5(x-3)\\\\y=5x-15+9\\\\y=5x-6

where x is the independent variable and y is the dependent variable

Have a great day.

Ms. Smith puts a variety of wrapped
marusya05 [52]

Using the binomial distribution, it is found that the number of students that would be expected to select a gold-wrapped candy  from the bag is given by:

  • B. 5 students

The candies are chosen with replacement, which means that for each student, the probability of choosing a gold wrapped candy is independent of any other student, hence the binomial distribution is used.

<h3>What is the binomial distribution?</h3>
  • The <em>binomial distribution</em> is the <u>probability of exactly x successes on n repeated trials, with p probability of a success on each trial</u>.

The expected value of the binomial distribution is:

E(X) = np

In this problem:

  • There are 15 students, hence n = 15.
  • Of a totlal of 5 + 1 + 2 + 4 = 12 candies, 4 are gold wrapped, hence p = \frac{4}{12} = \frac{1}{3}

Then, the <em>expected value</em> is:

E(X) = np = 15\times \frac{1}{3} = 5

Hence, option B is correct.

How many enantiomeric pairs are possible for an aldohexose?<br> a.2<br> b.4<br> c.8<br> d.16?
seraphim [82]
Based on this question, one thing that we would seriously consider would be the fact of first, doing 2^4 first. By doing this, it would then give us our answer as 16. By us understanding this point of view, we would then consider that this would then be your answer. That would then include that there would then be 16 pairs of the "enantiomeric pairs", and that would then be the possible estimate.
