A bag of marbles has 10 red marbles, 4 green marbles, and 6 blue marbles. A marble is randomly drawn from the bag before another marble is drawn, without replacement. What is the probability that a green marble and then a red marble are selected? Enter your answer as a fraction in simplest form in the box
Answer:
Step-by-step explanation:
A bag contains 8 red marbles, 3 blue marbles and 7 green marbles.
Total = 18 marbles.
Probability of drawing three red marbles = probability of drawing one red without replacement + probab of drawing another without reeplacement + probab of drawing a third without replacement.
Probability of drawing three red marbles = 8/18 + 7/17 + 6/16 = 0.4444 + 0.4118 + 0.3750 = 1.2312.
brainley i give if answer fast
Answer:
The answer is 9/7 because you know 1 is 7/7, so it's like 7/7 and 2/7. This means it is 7/7 plus 2/7, which makes it 9/7. So the answer is 9/7 hope it helped!
Step-by-step explanation:
Match each value on the left with the number on the right that includes that value.

If f(x) = g(x) + 4, find g(x) for f(x) = 3x + 2
Can someone please help?
Answer:
see below
Step-by-step explanation: 5 23 15 03
f(x) = g(x) + 4 find g(x) for f(x) = 3x + 2
sub f(x) = 3x + 2 into f(x) = g(x) +4
3x + 2 = g(x) + 4
3x + 2 - 4 = g(x) + 4 - 4
3x - 2 = g(x)
9514 1404 393
Answer:
g(x) = 3x -2
Step-by-step explanation:
Solve the given equation for g(x):
f(x) = g(x) +4
f(x) -4 = g(x) . . . . . subtract 4
(3x +2) -4 = g(x) . . . . . use the definition for f(x)
g(x) = 3x -2 . . . . . . . . . . . . . simplify

Write the equation in point-slope form of the line that passes through (1, 4) and has a slope of 4/3
Answer:
y - 4 = (4/3)(x - 1)
Step-by-step explanation:
point slope form is
y - y1 = m(x - x1)
m is the slope
(x1, y1) is a point on the line
----------------------------
for m = 4/3 and (x1, y1) = (1, 4)
y - 4 = (4/3)(x - 1)
Please solve these two questions!
Can someone answer this please
Answer:
<COB = 50°
Step-by-step explanation:
We can say that m<AOC + m<COD + m<DOB = 180° because the three mentioned angles form a straight line. We can substitute to get:
3x + 94 + x + 18 + 2x - 4 = 180
Then, we can combine like terms:
6x + 108 = 180
6x = 72
x = 12
We can see that m<COB is the sum of m<COD and m<DOB. We can wrote an equation to model the situation:
m<COB = m<COD + m<DOB
m<COB = x + 18 + 2x - 4
m<COB = 3x + 14
We have the value of x, so we can substitute that in:
<COB = 3(12) + 14
<COB = 36 + 14
<COB = 50°
Match the graph with its equation.

There are 3 apples, 4 oranges and 1 pear in a bag. Find each probability
1) Select an orange and then a pear(without replacement)
2)You select an orange then an apple then a pear without replacement
3)You select an Apple, then an orange, then another apple without replacement
Help please
Answer:
8 fruit total
1) orange probability: 4/8 = 1/2
pear probability after one fruit is taken out: 1/7
probability of getting one then the other without replacement: 1/2 x 1/7 = 1/14
2) orange: 1/2
apple: 3/7
pear: 1/6
probability of getting them in order without replacement: 1/2 x 3/7 x 1/6 = 1/28
3) apple: 3/8
orange: 4/7
apple: 2/6 = 1/3
probability of getting them in order without replacement: 3/8 x 4/7 x 1/3 = 1/14
Answer:2/6 or 33% chance of getting an apple, 3/24 or 13% of getting a pear and 13/24 or 54% chance of getting an orange hope that helps.
Step-by-step explanation:
The ratio of the side lengths of figure A and figure B is 1:3. If the volume of figure A
is 5 m^3, what is the volume of figure B?
45 m^3
30 m^3
135 m^3
15 m^3
Answer:
D)15m³
Step-by-step explanation:
the given ratio tells us that the Volume of figure-B is three times as much as the Volume of figure-A
so we acquire:
[tex] \displaystyle A _{ \text{figure - B}} = A _{ \text{figure - A}} \times 3[/tex]
substitute the given volume of the figure-A:
[tex] \displaystyle A _{ \text{figure - B}} =5 {m}^{3} \times 3[/tex]
simplify multiplication:
[tex] \displaystyle A _{ \text{figure - B}} =15 {m}^{3} [/tex]
hence, our answer is D)

Zach's parents put $1,500 in her bank account for college tuition. At an interest rate of
8.25% compounded weekly, what will be the balance after 18 years? (Make sure you
answer is in dollars and rounded to 2 decimal places)
Answer:
After 18 years, Zach's account balance will be $ 6,614.66.
Step-by-step explanation:
Given that Zach's parents put $ 1,500 in her bank account for college tuition at an interest rate of 8.25% compounded weekly, to determine what will be the balance after 18 years the following calculation must be performed:
1,500 x (1 + 0.0825 / 52) ^ 18x52 = X
1,500 x 1.00158653 ^ 936 = X
6,614.66 = X
Therefore, after 18 years, Zach's account balance will be $ 6,614.66.

at the end of a party there was one half pizza left over seven friends decided to divide the pizza equally. what fraction of the whole pizza did each friend have?
Answer:
Each friend only got 1/14 of the pizza.
Step-by-step explanation:
Each friend gets one slice of pizza, and there are 7, so you'd think just do 1/7 and that is the answer. However, it is talking about after the party where only have of the pizza is left. So you have to do 1/7*1/2 which equals 1/14.

Range:
Interquartile range:
Variance:
Standard deviation:
Range: 19
Interquartile range: 6.5
Variance: 44.86
Standard deviation: 6.70
Step-by-step explanation:
Given set:
27, 25, 20, 15, 30, 34, 28, 25.
(i) Range is the difference between the largest value and smallest value in a given data.
In the data above, the;
largest value = 34
smallest value = 15
Range = largest - smallest
Range = 34 - 15
Range = 19
(ii) Interquartile range is the difference between the median (Q₁) of the lower half of the given data, and the median (Q₃) of the upper half of the given data. i.e Q₃ - Q₁.
This should be done after ordering the given data in ascending order.
Ordering the above data gives:
15, 20, 25, 25, 27, 28, 30, 34
In the data above;
lower half = 15, 20, 25, 25
upper half = 27, 28, 30, 34
Find median (Q₁) of the lower half
Since there are even number of data, the median is the average of two middle numbers (20 and 25) i.e.
Q₁ = [tex]\frac{20+25}{2}[/tex] = [tex]\frac{45}{2}[/tex] = 22.5
Find median (Q₃) of the upper half
Since there are even number of data, the median is the average of two middle numbers (28 and 30) i.e.
Q₃ = [tex]\frac{28+30}{2}[/tex] = [tex]\frac{58}{2}[/tex] = 29
Interquartile range = Q₃ - Q₁
Interquartile range = 29 - 22.5
Interquartile range = 6.5
(iii) Variance is the measure of variability of a given set of data. It is calculated by following these steps:
=> First find the mean of the data by summing the numbers and dividing by the number of numbers. i.e
mean(x) = [15 + 20 + 25 + 25 + 27 + 28 + 30 + 34] / 8
mean(x) = [204] / 8
mean(x) = 25.5
=> Next, get the mean deviation by subtracting the mean from each individual value in the given set of data. i.e
15 - 22.5 = -7.5
20 - 22.5 = -2.5
25 - 22.5 = 2.5
25 - 22.5 = 2.5
27 - 22.5 = 4.5
28 - 22.5 = 5.5
30 - 22.5 = 7.5
34 - 22.5 = 11.5
=> Next, find the square of each of the results obtained above. i.e
(-7.5)² = 56.25
(-2.5)² = 6.25
(2.5)² = 6.25
(2.5)² = 6.25
(4.5)² = 20.25
(5.5)² = 30.25
(7.5)² = 56.25
(11.5)² = 132.25
=> Next, add all the results above together as follows;
56.25 + 6.25 + 6.25 + 6.25 + 20.25 + 30.25 + 56.25 + 132.25 = 314
=> Now, obtain the variance by dividing the result above one less than the number of numbers.
The number of numbers is 8. One less than this gives 7.
Therefore,
Variance = 314 / 7
Variance = 44.86
(iv) Standard deviation is the measure of how the numbers in the given data are spread out. It is calculated as the square root of variance.
Therefore,
Standard deviation = √variance.
Variance has been calculated above.
Standard deviation = √44.86
Standard deviation = 6.70
