Answer:

Your answer will be 90

Step-by-step explanation

First you will have to answer what's inside the parentheses

7 + 4 = 11 , 7 + 9 = 16

Then you multiply what is next to the parentheses

3×11 = 33, 2×16 = 32

Finally you will have to add

20 + 33 =53

53 + 5 =58

58 + 32 = 90

<em><u>The point is doing PEMDAS</u></em>

<em>P=Parentheses</em>

<em>E= Exponent</em>

<em>M= Multiplication</em>

<em>D= Division</em>

<em>A= Addition</em>

<em>S= Subtraction</em>

Answer:

90

Step-by-step explanation:

Be sure to use PEMDAS. Begin with parentheses, the move to multiplication, then adding.

20 + 3(7 + 4) + 5 + 2(7+9)

20 + 3(11) + 5 + 2(16)

20 + 33 + 5 + 32

You can add those final four numbers in any order you want, to get a sum of 90.

A junior high principal runs a report to determine what ratio of all 100 students take the bus to school or are dropped off by p

ratelena [41]

The probability that a student is in seventh grade, given that he/she is dropped off by parents is <u>option C)</u> 0.22

<u>Step-by-step explanation</u>:

The total probability of students in 7th grade = 0.56
The probability of 7th grade students dropped by parents = 0.12

P(student is in 7th grade student is in seventh grade) = P(students in 7th grade) / P(7th grade students dropped by parents).

⇒ 0.12/0.56

⇒ 0.22

What is the derivative of y=tan(arcsin(x))?

Anuta_ua [19.1K]

Hello,

(tg(x))'=1/cos²(x)

(arcsin(x))'=1/√(1-x²)

cos²(arcsin(x))=1-sin²(arcsin(x))=1-x²

$(tg(arcsin(x)))'= \dfrac{1}{cos(arcsin(x)))^2} * \dfrac{1}{\sqrt{1-x^2}} \\

=\dfrac{1}{1-sin(arcsin(x))^2}* \dfrac{1}{\sqrt{1-x^2}} \\

= \dfrac{1}{1-x^2} * \dfrac{1}{\sqrt{1-x^2}} \\

\boxed{= \dfrac{\sqrt{1-x^2}}{x^4-2x^2+1}}\\
