Are the events independent or dependent. From a bag containing 10 marbles, 5 red, 3 black, 1 blue, and 1 white we pick two marbles:
Event A: Selecting a red marble first pick, and then without replacement
Event B: Selecting a white marble on the second pick
Answer:
Dependent
Step-by-step explanation:
The first draw has 10 marbles, the second draw has 9 marbles and the color of those 9 marbles depends on the marble picked in the first draw so the events are dependent.
Answer:
Dependant
Step-by-step explanation:
It would be independent if you put the marble BACK, because at first it was 1/10 to get the white marble and then it became 1/9.
Combine the following complex numbers.
(16 − 6i) − (2 − 3i)
Answer:
14 - 3i
Step-by-step explanation:
Distribute the minus sign amongst the second equation:
(16 - 6i) - (2 - 3i) = 16 - 6i - 2 + 3i
Solve:
16 - 6i - 2 + 3i:
16 - 2 - 6i +3i
14 - 3i

Determine the domain of the function (f o g)((x) where:
Answer: You have the correct answer. It's choice B
Domain = [tex]\left(-\infty, \frac{2}{5}\right)[/tex]
Nice work.
=========================================================
Explanation:
The domain of g(x) is found by setting 2-5x greater than or equal to 0 and solving for x. We're doing this to ensure that 2-5x is not negative.
[tex]2-5x \ge 0\\\\2 \ge 5x\\\\5x \le 2\\\\x \le \frac{2}{5}[/tex]
So we can plug in any number smaller than 2/5, or we can plug in 2/5 itself, into the g(x) function to get some output.
However, notice that if x = 2/5, then g(x) = 0. This then would feed into the f(x) function and lead to a division by zero error. Therefore, x = 2/5 must be kicked out of the domain of (f o g)(x). We keep everything else that we found earlier.
In short, the domain as an inequality is [tex]x < \frac{2}{5}[/tex], which is the same as saying [tex]-\infty < x < \frac{2}{5}[/tex] and that converts to the interval notation [tex]\left(-\infty, \frac{2}{5}\right)[/tex]
We don't use a square bracket because we don't want to include the endpoint 2/5.
When x= 1, then y=

cos 0 = 12/15. find sin 0.
Answer:
[tex]sin \theta = \frac{3}{5}[/tex]
Step-by-step explanation:
[tex]cos \theta = \frac{12}{15}\\\\cos^2 \theta = 1 - sin^2 \theta\\\\sin^2\theta = 1 - cos^2 \theta\\\\[/tex]
[tex]= 1 - (\frac{12}{15})^2\\\\= 1 - \frac{144}{225}\\\\= \frac{225 - 144}{225}\\\\=\frac{81}{225}[/tex]
[tex]sin \theta = \sqrt{\frac{81}{225}} = \frac{9}{15} = \frac{3}{5}[/tex]

Josie and her brothers and sisters measured their heights and found the mean averageThe mean was 150cmJosie forgot her height. Can you work out Josie's height? 150cm, 170cm, 140cm, 155cm
Answer:
135 cm
Step-by-step explanation:
Let Jose's height = x
The mean of their heights = 150
Given the Heights:
150cm, 170cm, 140cm, 155cm
The mean is the sum if the heights divided by the number of people
Here :
(150 + 170 + 140 + 155 + x) / 5 = 150
(615 + x) / 5 = 150
615 + x = 750
x = 750 - 615
x = 135 cm

Given : Scale drawing of Angel's rectangular room is 5cm by 7 cm
We know that, Area of a rectangle is given by : Length × Width
⇒ Area of Angel's rectangular room = (5 cm × 7 cm) = 35 cm²
Given : The scale is 1 cm = 4 feet
⇒ Area of Angel's rectangular room in square feet = 35 × (4 feet)²
⇒ Area of Angel's rectangular room in square feet = 35 × 16 feet²
⇒ Area of Angel's rectangular room in square feet = 560 feet²
A biologist is studying the plant diversity in 15 million acres of the Sierra Nevada Mountains. He will count the number of species in 150 acres. Match the strategies to their corresponding sampling techniques.
1- The biologist classifies the Sierras into 10 different ecological types and then makes sure that the proportion of each ecological type from the sample is the same as the proportion of that of the population.
2- The biologist orders the 15 million acres by latitude and then surveys every 100000th acre on the list.
3- The biologist goes to 15 diverse locations that have 10 acres each and surveys all 10 acres for each of these 15 locations.
4- The biologist enters the 15 million acres into a data base and had a computer randomly select 150 of these acres.
5- The biologist goes to his 150 favorite hiking places and looks at an acres along each trail.
A. Cluster Sampling
B. Stratified Sampling
C. Systematic Sampling
D. Convenience Sampling
E. Simple Random Sampling
Answer:
The correct answer is -
1. B. stratified sampling
2. C. Systematic Sampling
3. A. Cluster Sampling
4. E. Simple Random Sampling
5. D. Convenience Sampling
Explanation:
Stratified sampling is a method in which samples have collected from a population that can be partitioned into subpopulations, categories or strata.
Systematic sampling is the method in which samples are at low risk of manipulation due to the getting samples ordered sampling range or frame.
Cluster sampling is the sampling that has random clusters of samples and data collected from selected clusters.
In a simple random sampling method, there are equal chances to get selected from a population in the sampling method.
Convenience Sampling is the sampling there is a selection of the data as these samples are convenient to collected and selected.

Ashley can ride her bicycle 15 miles in 2 hours. There are 60 minutes in 1 hour, and there are 1,760 yards in 1 mile. How many yards does Ashley travel in a minute ??
Answer:
220 yards in one minute
Step-by-step explanation:
15 miles in 120 minutes equals 26,400 (15 · 1760) yards in 120 minutes
26,400 yards in 120 minutes equals 220 yards in 1 minute (after dividing both 26400 and 120 by 120)
Answer:
220

The answer would be 30 because the triangle is 10, the circle is 5, and each black triangle is 2 which would be 10 plus 5 which is 15 then times 2 which is 30.
Answer:
20?
Step-by-step explanation:
If 3 triangles = 30 they we could assume that each triangle = 10
10 + 10 + 10 = 30
If one triangle = 10 then the 2 circles would = 5 in the 2nd equation
10 + 5 + 5 = 20
If 1 circle = 5 then the 1 full squares would = 4
5 + 4 + 4 = 13
1 triangle = 10 , 1 circle = 5, Half a square = 2
10 + 5 * 2 = ?
Using PEMDAS we would multiply 2 and 5 first to get 10
10 + 10 = 20

Find the equation of the line through (6,8) which is parallel to the line y=4x−6.
Give your answer in the form y=mx+b.
Answer:
[tex]y=4x-16[/tex]
Step-by-step explanation:
Hi there!
What we need to know:
Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope of the line and b is the y-intercept (the value of y when x is 0)Parallel lines always have the same slope1) Determine the slope (m)
[tex]y=4x-6[/tex]
4 is in the place of m, making it the slope. Because parallel lines have the same slope, the slope of the line is therefore 4. Plug this into [tex]y=mx+b[/tex]:
[tex]y=4x+b[/tex]
2) Determine the y-intercept (b)
[tex]y=4x+b[/tex]
Plug in the given point (6,8) and solve for b
[tex]8=4(6)+b\\8=24+b[/tex]
Subtract 24 from both sides to isolate b
[tex]8-24=24+b-24\\-16=b[/tex]
Therefore, the y-intercept of the line is -16. Plug this back into [tex]y=4x+b[/tex]:
[tex]y=4x-16[/tex]
I hope this helps!
Answer:
y=4x−16
Step-by-step explanation:
Because we want a parallel line to the given one, we know it needs to have the same slope. Therefore, the new line must be y=4x+b for some b. Knowing that the line goes through the point (6,8), we can plug this in and solve for b:
y=4x+b
8=4(6)=b
b=-16
So the equation of the line is y=4x−16.

(-5,-3)
,(7,5),
(-4,0)
(1,-2)
Answer:
(1,-2)
Step-by-step explanation:
Choose any value for x that is in the domain to plug into the equation.
Choose 0 to substitute in for x to find the ordered pair.
(0, -19/6)
Choose 1 to substitute in for x to find the ordered pair.
Remove parentheses.
y= -19/6 + 7(1)/6
Simplify
y=2
Use the
x and y values to form the ordered pair.

You have an investment account in which you invest $3,000 at 9.5%. If the account is compounded bi-monthly, how much money will be in the account after 10 years?
Answer:
$5850 is the answer
Step-by-step explanation:
P = $3000
R = 9.5%
T = 10 year
A = ?
So,
I = PTR/100
=(3000×9.5×10)/100
=285000/100
= $2850
So,
I = A-P
I+P = A
$2850 + $3000 = A
so, A = $5850
