please answer the question below
what is the measure of efg if efh=111?
Answer:
43°
Step-by-step explanation:
∠EFG+∠GFH=∠EFH
So (3x-20)+(3x+5)=111.You don't need the parenthesis, 3x-20+3x+5=111Combine like terms, 6x-15=111Add 15, 126Divide by 6 to isolate the variable, x=21∠EFG is (3x-20) and we know x is 21. 3(21)-20=63-20=43.
Before multiplying fractions change any mixed numbers to
[A] decimals
[B] estimated numbers
[C] percent
[D] improper fractions
9514 1404 393
Answer:
[D] improper fractions
Step-by-step explanation:
The usual recommendation for doing much of anything with mixed numbers is to change them to improper fractions.
__
However, that isn't always necessary. If you're doing the arithmetic with a calculator, it can be helpful to convert them to decimal numbers.* Sometimes, you can work with mixed numbers by working with the integer and fractional parts separately.
Sometimes a simple rewrite makes working with mixed numbers easier. (That is, converting part of the integer portion to a fraction may be useful in some cases.
Example:
(29 1/3) × (1/2) = (28 4/3) × (1/2) = 14 2/3
_____
* Some calculators will do arithmetic directly with mixed numbers and/or fractions. If yours doesn't, it can be helpful to memorize the decimal equivalents of a few common fractions: 1/3, 2/3, 1/6, 1/7, 1/9, 1/11 for example. This will help you convert the decimal result back to a mixed number.

The answer is the 3rd answer.
Let f be a function such that f(2) ≤ f(x) for all values of x in the interval (0, 3). Does f(2) represent a relative minimum or a relative maximum?
Answer: f(2) is a relative minimum
This is because f(2) is the lowest y output for any given y = f(x) output on the interval [tex]0 < x < 3[/tex] which is what the interval notation (0,3) indicates.
Draw out a "parabolic" like shape where the lowest point occurs at (2, f(2)), where f(2) is unknown, but we at least know that x = 2. I put "parabolic" in quotes because it may not be a true parabola, but it looks like one. This lowest point only applies for the neighbor hood [tex]0 < x < 3[/tex].

Solve 5(w-2)=-2(1.5w+5) plz and thank you
Step-by-step explanation:
5(w-2)=-2(1.5w+5)
5w-10=-3w-10
8w=0
w=O
Answer:
W=0
Step-by-step explanation:
5(w-2)=-2(1.5w+5)
5w-10= -3w-10
5w+3w=-10+10
8w=0
W=0
So the value of w is 0

You are going to have a quiz with 5 true/false questions next Friday. You
want to find the probability of passing the quiz, if you guess on each
question.
Create a simulation that would represent this situation and complete 10
trials. Show all of your work for full credit.
Based on the binomial probability principle, the probability of passing the quiz if all answers are guessed [tex] P(x = k) = 10Ck \times 0.50^{k} \times 0.50^{10-k} [/tex]
Let :
Number of questions passed = kNumber of trials, n = 10Probability of success, p = 1/2 = 0.50q = 1 - p = 1 - 0.50 = 0.50Using the binomial probability relation :
[tex] P(x = x) = nCx \times p^{x} \times q^{n-x} [/tex] x = kSubstituting the values into the relation :
[tex] P(x = k) = 10Ck \times 0.50^{k} \times 0.50^{10-k} [/tex]
Hence, the required probability expression is [tex] P(x = k) = 10Ck \times 0.50^{k} \times 0.50^{10-k} [/tex]
