liraira [26]

Answer:

2/5, 0.4, 40%

7/10, 0.7, 70%

1/2, 0.5, 50%

1/2, 0.5, 50%

4/5, 0.8, 80%

3/5, 0.6, 60%

3/10, 0.3 ; 30%

Step-by-step explanation:

Sample space = (1, 2, 3, 4, 5, 6, 7, 8, 9, 10)

P(less Than 5) :

Required = (1, 2, 3, 4) = 4 observations

P(less than 5) = 4 / 10 = 2 / 5 = 0.4 = 40%

Greater than 3) = (4, 5,6,7,8,9,10) = 7 observations

P greater Than 3) = 7/10 = 0.7 = 70%

Odd = (1,3,5,7,9) = 5

P(odd) = 5 / 10 = 1/2 = 0.5 = 50%

(even) = (2,4,6,8,10) = 5

P(even) = 5 / 10 = 1/2 = 0.5 = 50%

Not a multiple of 4 = (1,2, 3,5,6,7,9,10) = 8

P(not A multiple of 4) = 8/10 = 4/5 = 0.8 = 80%

not 5, 6, 7, or 8 = (1,2,2,4,9,10).= 6

P(not 5, 6, 7, or 8) = 6 / 10 = 3/5 = 0.6 = 60%

Divisible by 3 = (3, 6, 9) = 3

P(divisible by 3). = 3/10 = 0.3 = 30%

\bf \displaystyle \int~\cfrac{sec^2(x)}{\sqrt{1+tan(x)}}\cdot  dx\\\\

u=1+tan(x)\implies \cfrac{du}{dx}=sec^2(x)\implies \cfrac{du}{sec^2(x)}=dx\\\\
-------------------------------\\\\
\displaystyle \int~\cfrac{\underline{sec^2(x)}}{\sqrt{u}}\cdot\cfrac{du}{\underline{sec^2(x)}}\implies \int~\cfrac{1}{\sqrt{u}}\cdot du\implies \int~u^{-\frac{1}{2}}\cdot du

What is the simplified value of the expression below?
slavikrds [6]

Answer:

I dont know the experssion but I will give you steps to figure it out!

Step-by-step explanation:

Before you evaluate an algebraic expression, you need to simplify it. This will make all your calculations much easier. Here are the basic steps to follow to simplify an algebraic expression:

remove parentheses by multiplying factors

use exponent rules to remove parentheses in terms with exponents

combine like terms by adding coefficients

combine the constants

When simplifying an expression, the first thing to look for is whether you can clear any parentheses. Often, you can use the distributive property to clear parentheses, by multiplying the factors times the terms inside the parentheses. In this expression, we can use the distributive property to get rid of the first two sets of parentheses.

Now we can get rid of the parentheses in the term with the exponents by using the exponent rules we learned earlier. When a term with an exponent is raised to a power, we multiply the exponents For example, (x2)2 becomes x4.

The next step in simplifying is to look for like terms and combine them. The terms 5x and 15x are like terms, because they have the same variable raised to the same power

Finally, we look for any constants that we can combine.

Now our expression is simplified. Just one more thing -- usually we write an algebraic expression in a certain order. We start with the terms that have the largest exponents and work our way down to the constants. Using the commutative property of addition, we can rearrange the terms and put this expression in correct order, like this.

Using simple mathematical operations, the missing values are as follows:

(B) Dijon Mustard: 18g

  • Increased by 20 = 360g

(C) Barbeque sauce: 70g

  • Increased by 5 = 350g
  • Increased by 20 = 1,400g

(D) Worcestershire sauce: 10.35g

  • Increased by 5 = 51.75g
  • Increased by 20 = 207g

(E) Kosher salt: 1.5g

  • Increased by 5 = 7.5g
  • Increased by 20 = 30g

(F) Ground black pepper: 2.3g

  • Increased by 5 = 11.5g
  • Increased by 20 = 46g

(G) Crushed red pepper: 1.15g

  • Increased by 5 = 5.75g
  • Increased by 20 = 23g

<h3>What do we mean by mathematical operations?</h3>
  • A mathematical "operation" is the process of calculating a value utilizing operands and a math operator.
  • There are predefined rules associated with the math operator's symbol that must be applied to the supplied operands or numbers.
  • The order of operations is a rule that outlines the proper steps to take when analyzing a mathematical equation.
  • We can recall the PEMDAS steps in the following order: Parentheses, Exponents, Multiplication, Division (from Left to Right), Addition, and Subtraction (from left to right).

So, we can calculate missing values as follows:

(B) Dijon Mustard: 18g

  • Increased by 20 = 18×20 = 360g

(C) Barbeque sauce: 70g

  • Increased by 5 = 70×5 = 350g
  • Increased by 20 = 70×20 = 1,400g

(D) Worcestershire sauce: 10.35g

  • Increased by 5 = 10.35×5 = 51.75g
  • Increased by 20 = 10.35×20 = 207g

(E) Kosher salt: 1.5g

  • Increased by 5 = 1.5×5 = 7.5g
  • Increased by 20 = 1.5×20 = 30g

(F) Ground black pepper: 2.3g

  • Increased by 5 = 2.3×5 = 11.5g
  • Increased by 20 = 2.3×20 = 46g

(G) Crushed red pepper: 1.15g

  • Increased by 5 = 1.15×5 = 5.75g
  • Increased by 20 = 1.15×20 = 23g

Therefore, using simple mathematical operations, the missing values are as follows:

(B) Dijon Mustard: 18g

  • Increased by 20 = 360g

(C) Barbeque sauce: 70g

  • Increased by 5 = 350g
  • Increased by 20 = 1,400g

(D) Worcestershire sauce: 10.35g

  • Increased by 5 = 51.75g
  • Increased by 20 = 207g

(E) Kosher salt: 1.5g

  • Increased by 5 = 7.5g
  • Increased by 20 = 30g

(F) Ground black pepper: 2.3g

  • Increased by 5 = 11.5g
  • Increased by 20 = 46g

(G) Crushed red pepper: 1.15g

  • Increased by 5 = 5.75g
  • Increased by 20 = 23g
