So the trick here is to look at the decimals. We can solve this problem like it’s 16×2, as long as we add the decimal points back in. so in this case the decimal points are in the tenths spot so we move them twice in the 32. I hope the picture helps too. Hope this helped!
Question 2(Multiple Choice Worth 2 points)
(Experimental Probability MC)
In a repeated experiment, Kim rolled a fair die twice. The theoretical probability of both rolls equaling a sum greater than 10 is 3 over 36. Predict how many times the rolls will result in a sum greater than 10 if the experiment is repeated 108 times.

9 the rolls will result in a sum greater than 10 if the experiment is repeated 108 times.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
The theoretical probability of both rolls equaling a sum greater than 10 is 3 over 36.
As, Expected number of outcomes = theoretical probability * number of trials
Expected number of outcomes = 3/36 x 108
= 9
Thus, the required value is 9.

Adrien has 4 liters of milk. He drinks y liters each day.
a) If Adrien has x liters of milk left after one week, express x in terms of y.
b) State the independent and dependent variables in the question
Answer:
A) X = 4 - 7Y
B) Independent Variable: Y, Dependent Variable: X
Step-by-step explanation:
Explanation for A:
We form a simple equation, knowing that if he drinks y liters each day after one week it would be 7Y. Then, we'd subtract it from 4
So equation would be X = 4 - 7Y
Explanation for B:
The independent is Y because doesn't change or get affected by another variable, and the dependent variable is X because depending on the value of Y, X will change accordingly.

Step-by-step explanation:
#18 complementary
3x +45 = 90
3x + 45-45 = 90 -45
3x = 45
Divide both sides by 3
3x/3 = 45/3
x = 15
#20 supplementary
2x + 3x + 25 = 180
5x + 25 = 180
5x + 25 - 25 = 180 -25
5x = 155
Divide both sides by 5
5x/5 = 155/5
x = 31
#15 - vertical
4x - 25 = 75
4x - 25 + 25 = 75 + 25
4x = 100
Divide both sides by 4
4x/4 = 100/4
x = 25
#16 - complementary
4x + 2x = 90
6x = 90
divide by 6 each side
x = 15
#19 complementary
x -20 + x = 90
2x -20 = 90
2x -20 + 20 =90 +20
2x = 110
Divide both sides by 2
2x / 2 = 110/2
x = 55

Ximena conducts a survey on how students spend their money.
Sample: 80 students randomly chosen as they leave the school.
Question: Do you spend the majority of your money keeping up with today's hottest music or on other things?
Claim: Students spend the majority of their money buying music.
Answer:
The claim that students spend the majority of their money buying music is not valid. The survey Ximena conducted is not representative of the entire population of students, as it only surveyed 80 students randomly chosen as they left the school. Therefore, the results of the survey cannot be used to make a general statement about how all students spend their money.

Write an equation to represent "33 is 15 less than k."
Answer: k - 15 = 33
Step-by-step explanation:
So basically you just translate the problem into math form. 33 is a #, is is an = sign so, 33 = so far. Then 15 is less than k, which is not 15 - k but k - 15. There's a difference. Say k is 30, so 30 - 15 and not 15 - 30. So then you have 33 = k - 15, then I just switched it around to look better and done.
Answer:
k-15=33

Answer:
Hence, 70 people out of 100 who had attained the previous year
Step-by-step explanation:
If this is completely proportional, you'd make the formula
[tex] \frac{420}{600} = \frac{x}{100} [/tex]
Cross multiply
[tex]42000 = 600x[/tex]
Then we just divide by 600
[tex]x = 70[/tex]
Hans spent a total of $30 at the grocery store. Of this amount, he spent $21 on fruit. What percentage of the total did he spend on fruit?
Answer: 70%
Step-by-step explanation:
The total answers count 30 - it's 100%, so to get a 1% value, divide 30 by 100 to get 0.30. Next, calculate the percentage of 21: divide 21 by 1% value (0.30), and you get 70.00%
Triangles ABC and DEC are similar. Side DE is 1.8 feet, side EC is 4 feet, and side BE is 0.8 foot.
Part A: Describe how to draw triangles ABC and DEC separately. Be sure to give the lengths of sides BC, DE, and EC in the description.
Part B: Find side AB. Show each step of your work.
The lengths of sides BC, DE, and EC in triangle DEC are given as [tex]4[/tex] feet, [tex]1.8 feet,[/tex] and 0.8 foot, respectively. The length of side [tex]AB[/tex] is approximately [tex]3.36[/tex] feet.
What is the line segment?Part A:
To draw triangles [tex]ABC[/tex] and [tex]DEC[/tex] separately, follow the steps below:
Draw a straight line segment DE with length [tex]1.8[/tex] feet.
From point D, draw a line segment DC perpendicular to DE with length 4 feet.
Connect point E and point C with a straight line segment EC.
From point B, draw a line segment BE perpendicular to BC with length 0.8 foot.
Draw a straight line segment BC that intersects line segment DC at point A.
Connect point A and point B with a straight line segment AB.
The lengths of sides BC, DE, and EC in triangle DEC are given as [tex]4[/tex] feet, [tex]1.8 feet,[/tex] and 0.8 foot, respectively.
Part B:
Since triangles [tex]ABC[/tex] and [tex]DEC[/tex] are similar, their corresponding sides are proportional. Let x be the length of side AB. Then we have:
[tex]AB/DE = BC/EC[/tex]
Substituting the given values, we get:
[tex]x/1.8 = BC/0.8[/tex]
Solving for BC, we get:
[tex]BC = 0.8x/1.8[/tex]
Since BC and EC are the two legs of a right triangle DEC, we can use the Pythagorean theorem to find BC:
[tex]BC^2 + EC^2 = DE^2[/tex]
Substituting the given values, we get:
[tex](0.8x/1.8)^2 + 4^2 = 1.8^2[/tex]
Solving for x, we get:
[tex]x = 1.8 * (sqrt(1.8^2 - 4^2)) / 0.8[/tex]
[tex]x \approx 3.36 feet[/tex]
Therefore, the length of side [tex]AB[/tex] is approximately [tex]3.36[/tex] feet.

ANSWER ASAP PLEASE What is the solution for the system of linear equations shown in the graph? a coordinate grid with one line that passes through the points 0 comma 1 and 1 comma 2 and another line that passes through the points 0 comma 0 and 1 comma negative 3
Step-by-step explanation:
The solution of for the system of linear equations shown in the graph is x = -1/2 and y = 3/2.
Given points of two lines:-
Line 1 : (0,0) , (1,-3)
Line 2 : (0,2) , (-1,1)
Let the Equation of Line 1 : y = mx + c
m = (-3-0)/(1-0) = -3/1 = -3
Putting (0,0) in y = mx + c, we get
0 = -3*0 + c
0 = 0 + c
c = 0
Hence,
Equation of Line 1 : y = -3x or y + 3x = 0 ...(1)
Similarly, we can find,
Equation of Line 2 : y = x + 2 or y - x = 2 ...(2)
(1) - (2),
4x = -2
x = -2/4 = -1/2
Putting the value of x in (2), we get,
y - (-1/2) = 2
y + 1/2 = 2
y = 2-(1/2)
y = 3/2
