Which equation represents the relationship between the number of liters, x, and the number of liquid pints, y?
O y = x + 5.55
Oy=x-5.55
O y = 2.11x
O Y - 211
Answers
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
Hence, the equation that represents the relationship between the number of liters, x, and the number of liquid pints, y is 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.

y = a(x - h)² + k

g(x) = -5(x - 3)²
Hence h = 3, k = 0, and the vertex is (3,0).
What are the x-intercepts of a function g(x)?They are the values of x for which g(x) = 0, hence:
-5(x - 3)² = 0

iii) we can solve this question using hyper geometric distribution:
(60C1 * 40C1)/ 100C2 = 0.48
(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

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:

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.
