Answer:
82.358
Step-by-step explanation:
You have to use PEMDAS to solve this question. Since M is the first one we have to multiply since M stands for multiplication.
676 • 122 - 45 + 69
82,472 - 45 + 69
Then you add because A is next.
82,472 - 114
Then finish it
82,358
Your answer would be = 82,358
I hope it helps! Have a great day!

What is the mean and median
of these data:2,5,9, 11, 19
Answer:
mean = 9.2
median = 9
Step-by-step explanation:
mean = sum of data / number of data
mean = 2 + 5 + 9 + 11 + 19 / 5
= 46 / 5
= 9.2
median = middle number
= 9

C. -9/-3
D. 9/-1
Answer:
A. 18
B. -3
C. 3
D. -9
Step-by-step explanation:
Simplify:
A. -9(-2) <== when multiplying two negatives, they make a positive
-9(-2) = 18
B. -9(+6)
-9(+6) = -3
C. -9/-3 <== when dividing two negatives, they make a positive
-9/-3 = 3
D. 9/-1 <== when dividing a # with a negative, it makes a negative
9/-1 = -9

Raegan mows two lawns, The first lawn is 5 meters long and 4 meters wide. The area of the second lawn is 2 times as big but has the same width as the first, what is the length of the second lawn
By solving a simple linear equation, we conclude that the length of the second lawn is 10 meters.
What is the length of the second lawn?We know that one of the lawns is 5 meters long and 4 meters wide, then its area is:
A = 4m*5m = 20m^2
The other is two times as big, so its area is 40m^2 and has the same width as the first one (4 meters), so if we define the length as L we can write:
40m^2 = 4m*L
Solving for L we get:
(40 m^2)/4m = L = 10m
The length is 10 meters.

Suppose a polynomial of degree 4 with rational coefficients has the given numbers as zeros. Find the other zero
-2, square root 5, 10/3
Step-by-step explanation:
The root is
-sqr root of 5.
First, we put these roots in the forn of
[tex](x - a)[/tex]
where a is the root
So we have
[tex](x - ( - 2))(x - \sqrt{5} )(x - \frac{10}{3} )[/tex]
[tex](x + 2)(x - \sqrt{5} )(3x - 10)[/tex]
[tex](3 {x}^{2} - 4x - 20)(x - \sqrt{5} )[/tex]
To get rid of that square root, let have another root that js the conjugate posive root of 5.
[tex](3 {x}^{2} - 4x - 20)(x - \sqrt{5} )(x + \sqrt{5} )[/tex]
[tex](3 {x}^{2} - 4x - 20)(x {}^{2} + 5)[/tex]
Which will gives us a rational coeffeicent of degree 4.
Why we didn't do
[tex](x - \sqrt{5} )[/tex]
?
Because
[tex](x - \sqrt{5} ) {}^{2} = {x}^{2} - 2 \sqrt{5} + 5[/tex]
If we foiled out we will still have a irrational coeffceint.

Answer:
12000 cm²Step-by-step explanation:

A = 120*100 = 12000 cm²Area
Length ×Breadth120(100)12000cm²There are ten balls in a bag. Three balls are black and seven balls are white. a One ball is chosen at random and then replaced. Then a second ball is chosen at random. Here are two events. D: the first ball is black S: the second ball is black Are D and S independent? Show your working.
Answer:
Given:
Total balls = 10Black balls = 3White balls = 7⇒ P(black ball) = 3/10 = 0.3
⇒ P(white ball) = 7/10 = 0.7
If one ball is chosen at random and replaced, the probabilities do not change between the first and second ball.
Let event D = first ball is black
Let event S = second ball is black
P(D) = 0.3
P(S) = 0.3 (since the first ball is replaced)
⇒ P(D ∩ S) = P(D) × P(S)
= 0.3 × 0.3
= 0.09
For Independent Events we know that: P(A ∩ B) = P(A) × P(B)
Therefore, as P(D ∩ S) = P(D) × P(S) the events are independent.

Every time Martina orders Chinese food, she gets egg drop soup. So, she decides to learn how to make it herself. Her recipe calls for 8 cups of broth, but she can only find 32-fluid-ounce cartons at the store. How many cartons should she buy?
cartons
Answer:
2 cartons
Step-by-step explanation:
Hey! To start, we need to determine what we already know, Martine needs 8 cups worth of broth, but can only find 32-fluid ounce cartons.
Next, we need to find what we need to know, how many fluid ounces are in a cup? There are 8 fluid ounces in 1 cup!
Now, all we need to do is convert our cups to be able to find out how many cartons we need! So, to do this, we are going to multiply our number of cups by the number of fluid ounces in just 1 cup (so 8!).
8 cups x 8 fluid ounces (per 1 cup) = 64 fluid ounces
So! Martina needs 64 fluid ounces of broth to be able to create her recipe!
But, we aren't finished just yet, as we need to find how many cartons Martina needs! Like we did before, we know that there a 32 fluid ounces in 1 carton so if we have 64 fluid ounces in the recipe, all we need to do is divide 64 by 32 to find out how many cartons we need!
64 fluid ounces (8 cups worth) ÷ 32 fluid ounces (per carton) = 2 cartons
Melina needs to buy 2 cartons of broth to be able to complete her recipe.

A survey of 100 people in New York City, NY found that.
• The probability that they take the subway each day is 0.85
• The probability that they take a Taxi each day is 0.6
• The probability that take the subway and taxi each day is 0.55
If a person is selected at random, then determine the probability thay they take either the subway or a taxi each day.
Answer: 0.9
Step-by-step explanation:
[tex]\mathrm{Total \ sample \ space \ $=100$} \\\mathrm{Event \ $A = \ taking \ subway \ each \ day}$$P(A)=0.85$$Event $B=$ taking taxi $\because P(B)=0.6$$$P(A \cap B)=0.55$$[/tex]
[tex]\begin{aligned}P(A \cup B) & \Rightarrow \text { Person taking either taxi/subway } \\&=P(A)+P(B)-P(A \cap B) \\&=(0.85-0.555)+(0.6-0.55)-0.55 \\&=1.45-0.55\\&\bf{=0.9} \end{aligned}[/tex]

Angle 1 and Angle 2 are complementary angles. The measure of Angle 1 is 66 degrees. The measure of Angle 2 is 2x degrees. Find the value of x.
Answer:
Step-by-step explanation:
Complementary angles add up to 90°
∠1 + ∠2 = 90°
66 + 2x = 90°
2x = 90° - 66°
2x = 24°
x = 24/2
x = 12°
∠2 = 2*12
∠2 = 24°
