What is the equation of the line that passes through
(-2, 4) and (2, 7)?
Answer:
\(y=\frac{3}{4}x+\frac{11}{2}\)
Step-by-step explanation:
Hi there!
We want to find the equation of the line that passes through (-2, 4) and (2, 7).
The most common way to write the equation of the line is in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept.
First, let's find the slope of the line.
The slope, calculated from two points is given as the formula \(\frac{y_2-y_1}{x_2-x_1}\), where \((x_1, y_1)\) and \((x_2, y_2)\) are points.
We have two points, which is needed to find the slope, but let's label their values to avoid confusion.
\(x_1=-2\\y_1=4\\x_2=2\\y_2=7\)
Now substitute those values into the formula.
m=\(\frac{y_2-y_1}{x_2-x_1}\)
m=\(\frac{7-4}{2--2}\)
Simplify
m=\(\frac{7-4}{2+2}\)
m=\(\frac{3}{4}\)
So the slope of the line is \(\frac{3}{4}\).
Substitute that value as m in y=mx+b
y=\(\frac{3}{4}x+b\)
Now we need to find b
As the equation passes through both (-2, 4) and (2, 7), we can substitute the values of either one of them in the equation to solve for b
Taking (-2, 4) for example,
Substitute -2 as x and 4 as y:
4=\(\frac{3}{4}(-2)+b\)
Multiply
4=\(-\frac{3}{2}\)+b
Add -3/2 to both sides
\(\frac{11}{2} = b\)
Substitute that value into the equation
y=\(\frac{3}{4}x+\frac{11}{2}\)
Hope this helps!

What is the sum of all frequencies in a frequency distribution? and why is the sum of all relative frequencies equal to 1?
Answer:
Cumulative Frequency:
The sum of all the frequencies for all classes is equal to the number of elements in the given data and that summation is termed as the cumulative frequency which defines the number of entries of that statistical data.
The sum of relative frequencies is also equal to one, since the sum of all fractional parts must equal the whole.

True. It is possible for a small treatment effect to still be statistically significant if the sample size is large enough.
We have,
Statistical significance is determined by the p-value, which measures the probability of obtaining the observed results if the null hypothesis (no difference between groups) is true.
A small treatment effect may still produce a low p-value if the sample size is large enough to detect even small differences.
However, the clinical significance of the treatment effect should also be considered in addition to statistical significance.

The sides of a triangle are 3x+ 2, 6x, and 5x. Find the expression to represent the perimeter. To find the perimeter, we ADD the three sides
Answer:
3x+2+6x+5x
Step-by-step explanation:
perimeter of triangle = side 1 + side 2 + side 3
expression of the perimeter of triangle 3x+2+6x+5x
perimeter of traingle = 14x + 6
The expression 14x + 2 represents the perimeter of the triangle in terms of "x."
To find an expression that represents the perimeter of a triangle.
The perimeter is the sum of all three sides of the triangle. We have three sides with different lengths given by the expressions 3x + 2, 6x, and 5x. To find the expression representing the perimeter, we just need to add these three sides together.
Let's represent the sides as follows:
- The first side of the triangle is denoted as "a," which has a length of 3x + 2.
- The second side is denoted as "b," with a length of 6x.
- The third side is denoted as "c," having a length of 5x.
Now, let's find the expression for the perimeter, which we'll call "P." To do that, we add the three sides together:
P = a + b + c
Substitute the given expressions for the sides into the equation:
P = (3x + 2) + (6x) + (5x)
Now, let's simplify the expression by combining like terms (terms with the same variable "x"):
P = 3x + 2 + 6x + 5x
To further simplify, add the coefficients of the "x" terms:
P = (3 + 6 + 5)x + 2
Now, add the coefficients: 3 + 6 + 5 = 14, so the expression for the perimeter becomes:
P = 14x + 2
The expression 14x + 2 represents the perimeter of the triangle in terms of "x."

Left F = ▽(x3y2) and let C be the path in the xy-plane from (-1,1) to (1,1) that consists of the line segment from (-1,1) to (0,0) followed by the line segment from (0,0) to (1,1) evaluate the ∫c F dr in two ways.
a) Find parametrizations for the segments that make up C and evaluate the integral.
b) use f(x,y) = x3y2 as a potential function for F.
a) The line integral over C is:
∫C F dr = ∫r1 F dr + ∫r2 F dr = 2/5 + 1 = 7/5.
b) The potential function at (-1,1) and (1,1) yields:
∫C F dr = f(1,1) - f(-1,1) = 2.
Parametrize the first segment of C from (-1,1) to (0,0) as r1(t) = (-1+t, 1-t) for 0 ≤ t ≤ 1.
Then the line integral over this segment is:
\(\int r1 F dr = \int_0^1 F(r1(t)) \times r1'(t) dt\)
=\(\int_0^1 (3(-1+t)^2(1-t)^2, -2(-1+t)^3(1-t)) \times (1,-1)\) dt
=\(\int_0^1 [6(t-1)^2(t^2-t+1)]\)dt
= 2/5
Similarly, parametrize the second segment of C from (0,0) to (1,1) as r2(t) = (t,t) for 0 ≤ t ≤ 1.
Then the line integral over this segment is:
∫r2 F dr = \(\int_0^1 F(r2(t)) \times r2'(t)\) dt
= \(\int_0^1(3t^4, 2t^3) \times (1,1) dt\)
= \(\int_0^1 [5t^4] dt\)
= 1
The line integral over C is:
∫C F dr = ∫r1 F dr + ∫r2 F dr = 2/5 + 1 = 7/5.
Let f(x,y) = \(x^3 y^2\).
Then the gradient of f is:
∇f = ⟨∂f/∂x, ∂f/∂y⟩ = \((3x^2 y^2, 2x^3 y)\).
∇f = F, so F is a conservative vector field and the line integral over any path from (-1,1) to (1,1) is simply the difference in the potential function values at the endpoints.
Evaluating the potential function at (-1,1) and (1,1) yields:
f(1,1) - f(-1,1)
= \((1)^3 (1)^2 - (-1)^3 (1)^2\) = 2
∫C F dr = f(1,1) - f(-1,1) = 2.

a balloon is inflated such as its radius is 7.00 cm. What is the volume of air inside the balloon in mL
Answer: 1440mL
Step-by-step explanation: none
A balloon is inflated such as its radius is 7.00 cm. The volume of air inside the balloon is 1436.76 mL.
A ballon is a nylon material that can be inflated with a gaseous air substance. When inflated with air substance, it usually takes a spherical shape.
The volume of a sphere is:
\(\mathbf{= \dfrac{4}{3}\pi r^3}\)
where;
r = radius = 7.00 cm∴
\(\mathbf{= \dfrac{4}{3}\pi \times (7.00)^3}\)
= 1436.76 cm³
Since 1 cm³ = 1 mL
Thus;
1436.76 cm³ = 1436.76 mLTherefore, we can conclude that the volume of air inside the balloon is:

Matthew helped clean the kitchen for 1/3 hour. He helped with the laundry for 1 1/2 hours.
Altogether, how many hours did Matthew help clean the kitchen and help with laundry?
Answer:
Step-by-step explanation:
To find the total amount of time Matthew spent cleaning the kitchen and helping with the laundry, we need to add the two times together. However, the times are given in different formats (1/3 hour and 1 1/2 hours), so we need to convert them to a common format first.
To convert 1 1/2 hours to a fraction, we can multiply the whole number (1) by the denominator of the fraction (2) and then add the numerator (1). This gives us:
1 1/2 = (1 × 2 + 1)/2 = 3/2
So Matthew spent 1/3 hour cleaning the kitchen and 3/2 hours helping with the laundry. Adding these two times together, we get:
1/3 + 3/2 = 2/6 + 9/6 = 11/6
So Matthew spent 11/6 hours cleaning and doing laundry. We can simplify this fraction by dividing the numerator and denominator by their greatest common factor, which is 1:
11/6 = 1 5/6
Therefore, Matthew spent 1 hour and 5/6 of an hour (or 1 hour and 50 minutes) cleaning and doing laundry.
