a+b17-13+4A bag contains 4 purple beads and 3 green beads. A bead is drawn and then replaced before drawing the second bead. Find the probability both beads drawn are green.
A.6/7
B.6/49
C.16/49
D.9/49
Answer:
9/49
Step-by-step explanation:
4 purple beads and 3 green beads. = 7 beads
P(green) = green / total = 3/7
It is replaced
4 purple beads and 3 green beads. = 7 beads
P(green) = green / total = 3/7
P( green ,replaced, green) = 3/7 * 3/7 = 9/49
Laiba, tauseef and Nadia walked 24,42 and 52 meters.What is the minimum distance that each of them can cover equally ?
Answer:
the minimum distance each of them can cover equally is 8 m.
Step-by-step explanation:
Given;
different distance covered by Laiba, tauseef and Nadia = 24 m, 42 m and 52 m
for the 24 m, distance covered by each = 24 m/3 = 8 m
for the 42 m, distance covered by each, = 42 m/3 = 14 m
for the 52 m, distance covered by each, = 52 m/3 = 17.33 m
From the results above, the minimum distance each of them can cover equally is 8 m.

What is the slope of this?
Answer:
-3/2
Step-by-step explanation:
the slope of a line is expressed as ratio y/x showing how many units y changes, when x changes a certain number of units.
so, going from A to B, x changes 4 units (from -3 to +1), and y changes 6 units (down, from +3 to -3). that makes the y change negative.
so, the slope is
-6/4 = -3/2

Which point gives the y-intercept of ƒ(x) = –x2 + 4x – 3?
Answer:
A) (0,-3)
Step-by-step explanation:
to get the y-intercept let x = 0, then
y = 0 + 0 -3
y = -3
Answer:
(0,-3)
Step-by-step explanation:
The y intercept is where x=0
ƒ(x) = –x^2 + 4x – 3?
f(0) = -0^2 +4(0)-3
f(0) = -3

Help pleasee geometry is hard
Answer:
Step-by-step explanation:
The formula for arc length is
[tex]AL=\frac{\theta}{360}*\pi d[/tex] where theta is the central angle. We are given the central angle when we are told that the measure of arc EFG is 240 degrees. The diameter is given as 36, so filling in:
[tex]AL=\frac{240}{360}*\pi (36)[/tex] which can be simplified down a bit to
[tex]AL=\frac{2}{3}*\pi (36)[/tex] and a bit more to
[tex]AL=2\pi(12)[/tex] which gives us, finally,
[tex]AL=24\pi[/tex]

Step-by-step explanation:
determine the zeros of the function f(x)=3x^2-7x+1.
Answer:
The zeros of the function will be when f(x) = 0. As 0 = 3x^2 - 7x + 1, you can use the quadratic formula to solve, finding that x = (7 + sqrt(37))/2 or (7 - sqrt(37))/2.

In case of Nina:
slope of graph = speed = 48-32/6-4 = 16/2 =8
y-32 =8(x-4)
y-32=8x-32

d=8t
at x= 0 i.e at t= 0
d= 0m
In case of Ryan:
slope =speed = 47.5-35=6-4 = 12.5/2 =6.25
y-35=6.25(x-4)

if c/d - a/b =x, a =2c, and b=5d, what is the value of c/d in terms of x?
a) 2/3 x
b) 3/4 x
c) 4/3 x
d) 5/3 x
Answer:
d) 5/3 x
Step-by-step explanation:
You substitute a for 2c and b for 5d, so your equation will look like this:
c/d - 2c/5d = x
Then you just simplify into x by making c/d into 5c/5d so you have a common denominator.
5c/5d - 2c/5d = x
3c/5d = x
5/3 is your answer

Find the volume of this cone.
Use 3 for T.
V = Tip?h
[?]cm3
19 cm
V ~
6cm
Answer:
81 cm ^3
Step-by-step explanation:
The volume of a cone is given by
V = 1/3 pi r^2 h where r is the radius and h is the height
We are given the diameter of 6 so the radius is 1/2 the diameter
r = 1/2 (6) = 3
V = 1/3 pi r^2 h
= 1/3 ( 3) * (3) ^2 * 9
= 81 cm ^3

Joan spilled 750ml of fruit punch while pouring into cups from a bucket which held 3.75 litres of punch. Calculate what % of punch was spilled
Answer:
Percentage of punch spilled = 20%
Step-by-step explanation:
1 liter = 1000 ml
750 ml = 750/1000
= 0.75 liter
Quantity of fruit punch spilled = 0.75 liter
Total volume of fruit punch in the bucket = 3.75 liters
Calculate what % of punch was spilled
Percentage of punch spilled = quantity of punch spilled / Total quantity of punch × 100
= 0.75 liter / 3.75 liters × 100
= 0.2 × 100
= 20%
Percentage of punch spilled = 20%

What is the explicit formula for this sequence?
-8,-3, 2, 7, ...
O A. an = 12 + (n - 1)5
O B. an = 5+(n-1)(-8)
O C. an=-8+ (n - 115
O D. an= -8+ (n - 1)(-5)
Answer:
[tex]\text{C. }a_n=-8+(n-1)5[/tex]
Step-by-step explanation:
The explicit formula for an arithmetic sequence is given by [tex]a_n=a_1+(n-1)d[/tex], where [tex]a_n[/tex] is the [tex]n[/tex]th, [tex]a_1[/tex] is the first them of the sequence, and [tex]d[/tex] is the common difference.
In the given sequence -8, -3, 2, 7, we can see that we're adding 5 to each term. Therefore, the common different is positive five (+5). We can also identify the first term is -8. Therefore, we have:
[tex]a_1=-8[/tex] [tex]d=5[/tex]Thus, the explicit formula for this sequence is:
[tex]\boxed{a_n=-8+(n-1)5}[/tex]
Find the factorization of the polynomal below 64x^2 + 48x + 9
Answer:
(8x + 3)²
Step-by-step explanation:
Since our polynomial is 64x² + 48x + 9, we multiply 64x² by 9 to get 64x² × 9 = 576x² since we cannot simplify the expression any further.
Next, we need to find the factors of 576x² that add up to give 48x, these are 24x and 24x.
So the expression is re-written as
64x² + 48x + 9 = 64x² + 24x + 24x + 9
Writing out all the common factors, we have,
64x² + 48x + 9 = 8x × 8x + 3 × 8x + 3 × 8x + 3 × 3
Factorizing we have
64x² + 48x + 9 = 8x(8x + 3) + 3(8x + 3)
64x² + 48x + 9 = (8x + 3)(8x + 3)
64x² + 48x + 9 = (8x + 3)²
