Answer:
0.6429
Step-by-step explanation:
Let, s = play a sport
c = participate in a club
P(s) = 0.14
P(s n c) = 0.09
probability that a student participates in
a club given that they also play a sport = P(c | s)
P(c | s) = P(c n s) / P(s)
P(c | s) = 0.09 / 0.14
P(c | s) = 0.64285
= 0.6429
Y is directly proportional to x² and y = 50 when x =5, Find
i) Equation connecting x and y
ii) The value of y when x= 4
iii) The value of x when y= 200
Answer:
Equation: y = 2(x^2)
Y-value = 32
X-value = 10
Step-by-step explanation:
y = k(x^2)
k symbolises proportionality.
solve for k:
50 = k(5^2)
50 = 25k
k =2
So...
equation is y = 2(x^2)
Value of y when x = 4,
y = 2 x 4^2
y = 2 x16
y = 32
Value of x when y = 200,
200 = 2(x^2)
100 = x^2
x = 10

What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the line are (2, 2) and (5, 8).
Now,
Since, The equation for the line is,
y = ax + b
Put x = 2, y = 2
2 = 2a + b .. i)
Put a = 5, y = 8;
8 = 5a + b . (ii)
Subtract (ii) from (i);
3a = 6
a = 2
And, 8 = 5a + b
8 = 5 x 2 + b
8 = 10 + b
b = - 2
Hence, We get;
⇒ y = 2x - 2

Point 4,6 is reflected across line y= X and then dilated by a factor of 1/2 using the origin as the center of dilation. What is the resultant point?
9514 1404 393
Answer:
(3, 2)
Step-by-step explanation:
Reflection across y=x swaps the coordinates:
(x, y) ⇒ (y, x)
Dilation by a factor of 1/2 multiplies each coordinate by 1/2.
(x, y) ⇒ (x/2, y/2)
The combination of these transformations gives you ...
(x, y) ⇒ (y/2, x/2)
(4, 6) ⇒ (3, 2)

Unfortunately, doing this kind of problem by hand would take a very long time. So I recommend using a graphing calculator. Specifically, one that can handle numeric integration. You'll need to find the area under the curve from t = 0 to t = 3. This will tell you the change in velocity during the time period from t = 0 to t = 3 seconds. You should find that
[tex]\displaystyle \int_{0}^{3}\frac{t+3}{\sqrt{t^3+1}}dt \approx 6.71005[/tex]
If you want to do this by hand, you can use Riemann rectangles to break up the area and find the area of each rectangle. Though use of a calculator is recommended here as well.
This result will add onto the initial velocity of 5 to get a final approximate result of 5+6.71005 = 11.71005 which rounds to 11.710

8x + 7 = 6x + 15
what is x
Answer:
x = 4
Step-by-step explanation:
i am smart
Answer:
X=4
Step-by-step explanation:
Simplifying
8x + 7 = 6x + 15
Reorder the terms:
7 + 8x = 6x + 15
Reorder the terms:
7 + 8x = 15 + 6x
Solving
7 + 8x = 15 + 6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6x' to each side of the equation.
7 + 8x + -6x = 15 + 6x + -6x
Combine like terms: 8x + -6x = 2x
7 + 2x = 15 + 6x + -6x
Combine like terms: 6x + -6x = 0
7 + 2x = 15 + 0
7 + 2x = 15
Add '-7' to each side of the equation.
7 + -7 + 2x = 15 + -7
Combine like terms: 7 + -7 = 0
0 + 2x = 15 + -7
2x = 15 + -7
Combine like terms: 15 + -7 = 8
2x = 8
Divide each side by '2'.
x = 4
Simplifying. Hope this helps :D

How do you graph y = 2/3x + 1
9514 1404 393
Answer:
see attached
Step-by-step explanation:
Easy way: use a graphing calculator.
__
Manually: plot the y-intercept and another point.
The given equation is in slope-intercept form:
y = mx + b . . . . . . . slope m, y-intercept b
For this line, the slope is 2/3, and the y-intercept is 1.
This means the line crosses the y-axis at y=1. You can plot that point on your graph.
The slope of 2/3 means the line will rise 2 units for each 3 units to the right. 3 units right of the y-axis is x=3. 2 units up from y=1 is y=3. So, another point on the line is (x, y) = (3, 3). Plot that point and draw a line through the points you have identified.

Write an explicit formula for an,
the nth
term of the sequence 31, 37,43, ....
Answer:
The formula for the nth term of this sequence is: 31 + (n-1)X6
Step-by-step explanation:
This is an arithmetic sequence (ie. each term is the last term with a fixed value added to it).
T1 =31
T2 = 37 = T1 + 6 = 31 + 6
T3 = 43 = T2 + 6 = 31 + 6 + 6 = 31 + 6X2
…
In general, the nth term is 31 + 6(n-1)
