Write an equation for the line in point-slope and slope-intercept forms.
Passes through (3, 5) and has a slope of 5/3.
point-slope form: y-y₁ = m(x-x₁)
=============
[tex]\rightarrow \sf y - 5 = \dfrac{5}{3} (x-3)[/tex]
slope-intercept form: y = mx + b
============
[tex]\rightarrow \sf y - 5 = \dfrac{5}{3}(x)+ \dfrac{5}{3}(-3)[/tex]
[tex]\rightarrow \sf y - 5 = \dfrac{5}{3}(x)-5[/tex]
[tex]\rightarrow \sf y = \dfrac{5}{3}(x)-5+5[/tex]
[tex]\rightarrow \sf y = \dfrac{5}{3}(x)[/tex]
point slope form:-
y-y_1=m(x-x_1)y-5=5/3(x-3)3(y-5)=5(x-3)3y-15=5x-15Slope intercept form
y=mx+b

What is the surface area of the covering to the nearest square inch?
The surface area of the covering of the cone to the nearest square inches is 788 inches²
Surface area of a conesurface area of a cone = πr(r + l)
where
r = radiusl = slant lengthTherefore,
diameter = 2(radius)
14 = 2r
r = 14 / 2
r = 7 inches
l² = 7² + 28²
l = √49 + 784
l = √833
l = 28.8617393793
l = 28.86 inches
Therefore,
surface area = 3.14 × 7 (7 + 28.86)
surface area = 21.98 × 35.86
surface area = 788.2028
surface area = 788 inches²

Answer:
x = 16/3, y = -1/9
Step-by-step explanation:
4x + 1 = 5(x-3y) - 6
3(x+6y) + 4 = 9y + 19
Simplify both equations
4x + 1 = 5x-15y - 6
-x + 15y = -7
3x + 18y + 4 = 9y + 19
3x + 9y = 15
Now multiply 3 on both sides for the first equation.
(easier for adding both equations)
-3x + 45y = -21
3x + 9y = 15
Add both equations
x cancels out
54 y = -6
y = -1/9
plug in to other equation
3x + 9y = 15
3x - 1 = 15
3x = 16
x = 16/3

The y-intercept is the b term in slope intercept form (y = mx + b) or in the form of a point (0, y).
Function 1 is in slope-intercept form, and the b term is 5.
Function 2 is given in a table, but it is easy to find the point (0, y) and y is 5.25.
5.25 > 5
Function 2 has the greater y-intercept.

Which statements are true about the data sets? check all that apply. set a is symmetrical. set b has the same mean and median. set b is right skewed. set a is left skewed. the median of set a is larger than the mean of set a.
1) The mean of set A is larger than the mean of set B.
2)The median of set A is larger than the median of set B.
A = {10, 12, 12, 6, 8, 5, 4, 10, 8, 10, 12, 12, 6}
B = {8, 8, 8, 7, 9, 7, 9, 10, 6, 8}
What is the mean?Mean is the ratio of the sum to the total number of observations.
Mean of set A = 115/13
Mean of set B =80/10 =8
So, the mean of set A is larger than the mean of set B.
Arranging both the sets in ascending order
A = {4, 5, 6, 6, 8, 8, 10, 10, 10 12, 12, 12, 12 }
Median of set A = middle term = 7th term = 10
Similarly, the median of set B =8
So, the median of set A is larger than the median of set B.
Thus, 1) The mean of set A is larger than the mean of set B.
2)The median of set A is larger than the median of set B.

What is the answer to this 3x+17=-2x-13???
Answer:
x = -6
Step-by-step explanation:
3x + 17 = -2x - 13
==> add 2x to both sides
5x + 17 = - 13
==> subtract 17 from both sides
5x = -30
==> divide both sides by 5

which of the following is an equations of the line passing through the points (-1,4) and (1,2)
Answer:
y = -1x + 3 or y = -x + 3 (**That is the last option which is D**)
Step-by-step explanation:
You need to do slope-intercept formula and the slope formula.
The Slope-Intercept Formula: y=mx+b
The Slope Formula: y2 - y1 / x2-x1
Your coordinates:
(-1,4) and (1,2)
2 - 4/1- (-1)
-2/2
Simplified is -1
Your "m" in the slope-intercept formula is -1
Formula: y=-1x + b
Now, you need to find the Y-Intercept which is the "b"
Using our slope-intercept formula, you need to plug in "x1" and "y1"
4 = -1(-1) + b
4 = 1 +b
4-1 = b
3 = b
So your equation is:
y = -1x + 3 or y = -x + 3

Carmen is going to roll an 8-sided die 200 times. she predicts that she will roll a multiple of 4 twenty-five times. based on the theoretical probability, which best describes carmen’s prediction? carmen’s prediction is exact because 200 times startfraction 1 over 8 endfraction is 25. carmen’s prediction is low because 200 times one-fourth is 50. carmen’s prediction is low because 200 divided by 2 is 100. carmen’s prediction is high because 200 divided by 25 is 8.
The expected value is 50 then Carmen’s prediction is low because 200 times one-fourth is 50. Then the correct option is B.
How to calculate the expectation value?Expectation can be taken as a weighted mean, weights being the probability of occurrence of that specific observation.
Thus, if the random variable is X, and its probability mass function is given as
[tex]E(X) = \sum_{i=1}^n( f(x_i) \times x_i)[/tex]
(n is the number of values X takes)
Carmen is going to roll an 8-sided die 200 times.
She predicts that she will roll a multiple of 4 twenty-five times.
The sample will be
Total event = 8 {1, 2, 3, 4, 5, 6, 7, 8}
Then the favorable event will be to roll an 8-sided die and get a multiple of 4. Then we have
Favorable event = 2 {4, 8}
Then the probability will be
[tex]\rm P = \dfrac{2}{8} = \dfrac{1}{4}[/tex]
A dice is rolled 200 times, then by the binomial theorem we have the expected value will be
[tex]E(x) = nP = 200 \times \dfrac{1}{4} = 50[/tex]

The length of a rectangle is 3 less than 4 times
the width. The perimeter is 34. Find the length
and width.
Let
x = width
4x-3 = length
w=x
P = 2w + 2L
34 = 2x + 2(4x-3)
L=4x-3
→ Perimeter = 2( Length + Width)
→34 = 2x + 2(4x-3)
→34 = 2x + 8x - 6
→34 = 10x -6
→10x = 34 +6
→10 x = 40
→x = 40/10
→x = 4
Width is 4 unit and length is (4*4 -3) = 13 unit.Hope this helped you!
