A bag contains 4 black balls and 6 white balls. Sarah picks a ball at random from the bag and replaces it back in the bag. She then picks another ball at random from the bag.
You may draw a tree diagram on paper to answer the following questions.
Calculate the probability that she picks
a) 2 white balls or 2 black balls
Answer:
13/25
Step-by-step explanation:
number of black balls = 4
number of white balls = 6
⇒ total number of balls = 10
As the balls are always replaced after being picked:
probability of picking a black ball = P(B) = 4/10probability of picking a white ball = P(W) = 6/10Therefore,
P(W) and P(W) = 4/10 x 4/10 = 16/100 = 4/25
P(B) and P(B) = 6/10 x 6/10 = 36/100 = 9/25
P(W and W) or P(B and B) = 4/25 + 9/25 = 13/25

7(-4x - 1) = 49
Not sure of steps
Answer:
Step-by-step explanation:
7(-4x - 1) = 49
-28x - 7 =49
-28x = 49 + 7 = 56
x = 56/(-28) = -2
Answer:
7 x - 4x = - 28x
7 x - 1 = - 7
-28x - 7 = 49
+7 both sides
-28x = 56
÷ - 28
x = 56/-28
x = - 2
I substitute to double check my answer:
- 4x
-4x-2 =8
7(8- 1)
7x 8 = 56
7 x - 1 = - 7
56-7= 49
Hope this helps!
Graph the following equation y+2=3/5(x+3)
Answer:
Step-by-step explanation:
It is given
2x−3y=5
we can write it as
3y=2x−5
So we get
y=32x−5
Substituting x=4 in the given equation
y=32(4)−5
So we get
Y=38−5
y=33
By division we get
y=1
Substituting x=−2 in the given equation
y=32(−2)−5
So we get
y=3−4−5
y=3−9
By division we get
y=−3
x 4 -2
y 1 -3
Now draw a graph using the points (4,1) and (−2,3)
Join the point through a line and find the value of y
(i) Based on the graph
consider x=4 on X-axis
Now the line joining the two points and a point on the Y-axis gives the value of y
Therefore,when x=4 the value of y=1
(ii) Based on the graph,
Consider y=3 on Y-axis
Now the line joining the two points and a point on the X-axis the value of x
Therefore, when y=3 the value of x=7
If an exterior angle measure of a regular
polygon is 20°, how many sides does the
polygon have? What is the measure of each interior angle?
Answer:
n=18 sides
Step-by-step explanation:
Given: Exterior angle =20°
Find: sides of a regular polygon
Solution: θ=(360°)/side , θ=20°
Let n= number of sides
θ=360°/n
20=360/n
n=360/20
n=18
find the value of x and give reasoning in the following image
Answer: 80
Step-by-step explanation:
Angle FGB = 80 degrees b/c supplementary angles.
By the sum of interior angles of a quadrilateral, angle FEB = 360 - 75 - 95 - 90 = 100 degrees.
x is supplementary with this angle and is this 180 - 100 = 80.
Solve the following inequality.
-10 < 5 + X <-5
[?] < < <[ ]
Enter
Solution:
Simplify the inequality one by one:
-10 ≤ 5 + x < -5=> -10 - 5 ≤ x => -15 ≤ x => 5 + x < -5=> x < -5 - 5=> x < -10This means that...
-15 ≤ x < -10Hoped this helped!
Required solution :
First solving for -10 < 5 + x
⇒-10 - 5 < x
⇒ -15 < x
Now for 5 + x < -5
⇒ x < -5 - 5
⇒ x < -10
Therefore,
-15 < x < -10Determine whether the triangles are similar by AA, SSS, SAS, or not similar
Answer:
Step-by-step explanation:
If Δ JKL ~ Δ JHG , then
[tex]\frac{LJ}{GJ}[/tex] = [tex]\frac{KJ}{HJ}[/tex]
[tex]\frac{95}{68}[/tex] ≠ [tex]\frac{87}{72}[/tex] ⇒ triangles are not similar
can anyone please help me please, i will give free brainliest
Answer:
1/2
Step-by-step explanation:
Yes, I agree.
Make a graph [tex]y=-\frac{4}{5}x+\frac{2}{5}[/tex]
The point of intersection of the line with x-axis is the solution of [tex]-\frac{4}{5}x+\frac{2}{5}=0[/tex]
Multiply by 5 on both sides, get -4x + 2 = 0, x = 2/4 = 1/2
The solution is 1/2.
When an object falls due to gravity on Earth, the acceleration is 9.8 m/s. A student drops a rock
down a mineshaft. It takes 3.00 seconds for the rock to hit the bottom of the shaft. What is the
velocity of the rock as it impacts?
Answer:
29.4 m/s
Step-by-step explanation:
Use v = at with a = 9.8 m/s^2 and t = 3.00 sec
v = 9.8 * 3.00 = 29.4 m/s

If you open a bank account with a $200 starting balance and it earns 2.5% interest, compounded annually, how much interest will you earn in 10 years?
Answer:
$56.02
Step-by-step explanation:
The account balance after 10 years is given by the future value formula:
FV = P(1 +r)^t . . . . . principal P invested at rate r compounded annually for t years
FV = $200(1 +0.025)^10 ≈ $256.02
The amount in excess of the original investment is the interest earned:
$256.02 -200.00 = $56.02 . . . . interest earned in 10 years
Answer:
$256.02
Step-by-step explanation:
Here is the formula: 200(1.025)^10.
The .025 is the percentage of the interest, and the 1 is the money you already have (which is 200). The ^10 is the 10 years.
If you take the (1.025)^10, you'll get an incredibly large number, 1.2800....
Take that large number and multiply it by the amount of money you originally have, $200. Then you'll get something like 256.0169... Round to the near hundredth, and you'll have 256.02

There are 6 classes going on a field trip. Each class has 26 students.
Each car can hold 5 students. How many cars are needed to get all
he students to the field trip?
Answer:
32 cars
Step-by-step explanation:
If each class has 26 students, we can multiply the number of classes, 6, by the amount of students in each class, to find the total amount of students going on the field trip.
6 * 26 = 156 students
Each vehicle can hold 5 students. To find the amount of vehicles needed to transport all the children, we need to divide the number of students by 5.
156 / 5 = 31.2 vehicles
I don't think they plan on driving 0.2 of a vehicle, so we would have to round. We can't round down because if we did, there would be one student left.
31 * 5 = 155 students
Unless the student plans on biking there, they would have to have 32 cars ready to drive the students to the field trip.

The total cost of an eraser, 2 similar pens and a ruler is $13. The total cost of 2 similar erasers, a pen and a ruler is $11. The cost of 3 erasers is the same as that of 2 rulers. Find the cost of a ruler.
Answer:
$3
Step-by-step explanation:
Let the cost of an eraser, a pen and a ruler be $e, $p, and $r respectively.
Given:
e +2p +r= 13 -----(1)
2e +p +r= 11 -----(2)
3e= 2r -----(3)
(1) ×3:
3e +6p +3r= 39 ----(4)
Substitute (3) into (4):
2r +6p +3r= 39
6p +5r= 39 -----(5)
(2) ×3:
6e +3p +3r= 33 -----(6)
Substitute (3) into (6):
2(2r) +3p +3r= 33
4r +3p +3r= 33
3p +7r= 33 -----(7)
Let's rewrite equations (5) &(7) so it's easier to compare them:
6p +5r= 39 -----(5)
3p +7r= 33 -----(7)
We can eliminate the term p to find the value of r. This can be done by making sure that the coefficient of p is equal in both equations.
(7) ×2:
6p +14r= 66 -----(8)
(8) -(6):
6p +14r -(6p +5r)= 66 -39
Expand:
6p +14r -6p -5r= 27
9r= 27
r= 27 ÷9
r= 3
Thus, the cost of a ruler is $3.
differentiate between factors and prime factors use relavant examples in your explanations?
Answer:
The factors of a number are all of the numbers that will divide into that number with no remainder. The prime factors of a number are the prime numbers that must be multiplied together to give the number. For example: The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The prime factors of 30 are 2, 3, and 5.
A shopkeeper sold a table for Rs 2400, he loses 6% of its cost price.find the cost price of the table.
Answer:
Table price is Rs 2544
Step-by-step explanation:
Table sold = Rs 2400
Losses = 6%
Now find 6% of 2400
( 2400 × 6 ) ÷ 100 = 144
Add this answer to table price sold
2400+ 144 = 2544
