solution for -4 5/6 +5 1/3
Answer:
1/2
Step-by-step explanation:
to solve this equation you must find the greatest common factor or gcf to make the denominators the same
that happens to be 6
so
-4 5/6 + 5 2/6
then you add
you can break them up at add them like this
(-4 + 5) + (-5/6 + 2/6)
1 + -3/6
-3/6 is also -1/2
1 + -1/2
1/2
that is your answer
Step 1: Choose a point on the line, such as (2, 5).
Step 2: Choose another point on the line, such as (1, 3).
Step 3: Count units to determine the slope ratio. The line runs 1 unit to the right and rises 2 units up, so the slope is StartFraction one-half EndFraction.
Step 4: Substitute those values into the point-slope form.
y – y1 = m(x – x1)
y – 3 = y minus y 1 equals m left-parenthesis x minus x 1 right-parenthesis. (x – 1)
Which of Talia’s steps is incorrect?
Step 1 is incorrect because it uses a point that is not on the line.
Step 2 is incorrect because it uses a point that is not on the line.
Step 3 is incorrect because it shows an incorrect ratio for the slope.
Step 4 is incorrect because it shows an incorrect substitution of (1, 3) into the point-slope form.
The step of Talia that's incorrect is: C. step 3 because the slope ratio she calculated is incorrect.
What is the Slope?The slope of a line (m) = rise/run = change in y / change in x.
Calculating the slope using two points on the line, (2, 5) and (1, 3), we should have:
Slope (m) = (5 - 3)/(2 - 1)
Slope (m) = (2)/(1)
Slope (m) = 2
This shows that the ratio of the slope calculated by Talia was wrong. The step that is incorrect is: C. Step 3

You sold a combined total of 25 of item A and item B. You made $88.
Item A: 3$
Item B: 4$
How much of each item did you sell?
Answer:
x = 25 - y = 2
Step-by-step explanation:
Let x represent the number of item A that you sold.
Let y represent the number of item B that you sold.
The total number of item A and item B sold is 25. This means that
x + y = 25
The cost of item A is $3, the cost of item B is $4 and if the total amount of money made is $88, this implies
3(x) + 4(y) = 88 (Substitute x = 25 - y)
→ 3(13 - y) + 4y = 88
→ 39 - 3y + 4y = 88
→ 39 + y = 16
→ y = 23
If y = 23, then x = 25 - y = 2

A class consists of 60 boys and 40 girls. If two students are chosen at random, what is the probability that i) both are boys ii) both are girls iii) one boy and one girl?
(i) Both are boys = 0.3575757576, (ii) Both are girls = 0.1575757576 and (iii) one boy and one girl = 0.48484848 are the probabilities.
What is the probability?The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.
Given:
A class consists of 60 boys and 40 girls.
To find the probability if two students are chosen at random:
The probability is ¹⁰⁰C₂.
(i) Both are boys,
The probability is ⁶⁰C₂ ÷ ¹⁰⁰C₂.
⁶⁰C₂ ÷ ¹⁰⁰C₂ = 60! / {2! x (60-2)!} ÷ 100! / {2! x (100-2)!}
⁶⁰C₂ ÷ ¹⁰⁰C₂ = 30 x 59 / 50 x 99
⁶⁰C₂ ÷ ¹⁰⁰C₂ =0.3575757576
(ii) Both are girls,
The probability is ⁴⁰C₂ ÷ ¹⁰⁰C₂.
⁴⁰C₂ ÷ ¹⁰⁰C₂ = 40! / {2! x (40-2)!} ÷ 100! / {2! x (100-2)!}
⁴⁰C₂ ÷ ¹⁰⁰C₂ = 20 x 39 / 50 x 99
⁴⁰C₂ ÷ ¹⁰⁰C₂ =0.1575757576
(iii) one boy and one girl,
The probability is ⁴⁰C₁ × ⁶⁰C₁ ÷ ¹⁰⁰C₂.
⁴⁰C₁ × ⁶⁰C₁ ÷ ¹⁰⁰C₂ =
40! / {1! x (40-1)!}x 60! / {1! x (60-1)!} ÷ 100! / {2! x (100-2)!}
⁴⁰C₁ × ⁶⁰C₁ ÷ ¹⁰⁰C₂ = 40x60 / 50 x 99
⁴⁰C₁ × ⁶⁰C₁ ÷ ¹⁰⁰C₂=0.48484848
Therefore, the probabilities are (i) Both are boys = 0.3575757576, (ii) Both are girls = 0.1575757576 and (iii) one boy and one girl = 0.48484848

Which of the following functions best models the data represented by the scatterplot shown below?
A: y=160x-100
B: y=2^x+12
C: y=8x^2+10
D: y=25x+20
Answer:
C: y = 8x^2 + 10.
Step-by-step explanation:
It looks close to being a parabola so I think it is probably a function in x^2.
Try 8x^2 + 10
Checking against the plot
When x = 5 , y = 8(5)^2 + 10 = 210 , and on graph its 200
Calculating y for other values:
When x = 7, y = 8(7)^2 + 10 = 402, and on graph y = 400.
When x = 11, y = 978 , and on graph = 1000.
When x = 17, y = 2322, and on graph y = about 2350.
What is the mean absolute deviation of the data set? Round to the nearest hundredth if necessary.
The mean absolute deviation, rounded to the nearest hundredth, is: 11.67 calories.
How to Find the Mean Absolute Deviation?To find the mean absolute deviation, find the mean of the data then find the average distance of each data point from the mean.
Given the data, 61, 42, 52, 27, 35, 23:
Mean = (61 + 42 + 52 + 27 + 35 + 23)/6
Mean = 240/6
Mean = 40
Mean absolute deviation = [(61 - 40) + ( 42 - 40) + ( 52 - 40) + ( 27 - 40) + ( 35 - 40) + ( 23 - 40) 6 = (21) + (2) + (12) + (13) + (5) + (17)] / 6 = 70/6

O y = 2.11x
O Y - 211
The equation that represents the relationship between the number of liters, x, and the number of liquid pints, y is y = 2.11x
How to determine the equation?The attached table of values represents the missing piece in the question.
Start by calculating the rate of change using:
m = (y2 - y1)/(x2 - x1)
This gives
m = (14.77 - 10.55)/(7- 5)
Evaluate
m = 2.11
The equation is then calculated using:
y = m(x - x1) + y1
This gives
y = 2.11(x - 5) + 10.55
Evaluate
y = 2.11x - 10.55 + 10.55
y = 2.11x

The two numbers where the digit 6 has a value of 0.6 are 14.63 and 85.62.
To determine in which two numbers the digit 6 has a value of 0.6, we need to examine the place value of 6 in each number.
Let's go through each number:
1. 16.7: The digit 6 is in the tens place, so its value is 6 * 10 = 60 (not 0.6).
2. 61.28: The digit 6 is in the ones place, so its value is 6 (not 0.6).
3. 14.63: The digit 6 is in the tenths place, so its value is 6 * 0.1 = 0.6.
4. 28.16: The digit 6 is in the hundredths place, so its value is 6 * 0.01 = 0.06.
5. 96.77: The digit 6 is in the tens place, so its value is 6 * 10 = 60 (not 0.6).
6. 85.62: The digit 6 is in the tenths place, so its value is 6 * 0.1 = 0.6.

cm and height of 17 cm what is the length of the base
Answer:

Step-by-step explanation:
Formula :
Area (parallelogram) = Base × Height
=========================================================
Given :
⇒ Area = 153 cm²
⇒ Height = 17 cm
===========================================================
Solving :
⇒ 153 cm² = 17 cm × Base
⇒ Base = 153/17
⇒ Base = 9 cm
Answer:
Base = 9 cm
Step-by-step explanation:
Given dimensions:
Area of the parallelogram: 153 cm^2 ( It should be cm^2 not cm )Height of the parallelogram: 17 cmTo Find:
The baseSolution:
This question is a bit tricky.Usually,the height and the base are given. We'll use the formula of area of parallelogram , then substitute/plug the values of height and area of parallelogram, with the exception of base as it's not given.
So recall the formulae of area of parallelogram:
[tex] \rm \: Area_{(Parallelogram)} = b \cdot{h}[/tex]
Here,b = baseh = heightPlug/substitute the values of area of parallelogram & height:
[tex]\rm \: 153 \: cm ^2 =b \cdot17 \: cm[/tex]
We created an equation.Solve it now.
Transpose 17 cm to the LHS:[tex] \implies \rm \cfrac{153 \: cm^2}{17 cm} = base[/tex]
Cancel 153/17 by 17:[tex] \implies \rm9 \; cm = \: base[/tex]
[tex] \implies \rm \: Base = 9\; cm[/tex]
Yes! We're done!
Hence,the base is 9 cm of the parallelogram.
