Answer:
The probability of not getting a white ball is: 3/4
Step-by-step explanation:
Probability is defined as the likeliness of occurrence of an event. The probability is denoted by p.
The sum of probability of occurrence of an event and non-occurrence of an event is 1.
Let p be the probability of getting a white ball
p = 1/4
Let q be the probability of not getting a white ball
q =?
The sum of p and q will be 1.
So,
[tex]p + q = 1\\q = 1-p\\q = 1 - \frac{1}{4}\\q = \frac{4-1}{4}\\q = \frac{3}{4}[/tex]
Hence,
The probability of not getting a white ball is: 3/4
Solve the equation.
4 (6 – x) + 4 = 2 (3x + 1) - 6
Answer:
x = 2.4
Step-by-step explanation:
Simplify.
24 - 4x + 4 = 6x + 2 - 6
Combine like terms (24 + 4 = 28, sorry for the confusion!)
28 - 4x = 6x - 4
Add x and add 4 to both sides.
10x = 32
x = 3.2
Answer:
x=3 1/5 or 3.2

Which two answer choices below would give you a value of 3 times larger than (820 + 220)?
A) 3(820 + 220)
B) 3(820) + 2(220)
C) 2460 + 660
D) 820 x 220 x 3
The expression that gives you a value of 3 times larger than (820 + 220) are:
3(820 + 220)
2460 + 660
Options A and C are the correct answer.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
(820 + 220)
= 1040
Now,
3 x 1040
= 3120
Now,
A)
3(820 + 220)
= 3 x 1040
= 3120
B)
3(820) + 2(220)
= 2460 + 440
= 2900
C)
2460 + 660
= 3120
D)
820 x 220 x 3
= 541200
Thus,
3(820 + 220) and 2460 + 660 give the value of 3 times larger than
(820 + 220).

A researcher conducts a hypothesis test using a sample of n = 40 from an unknown population. What is the df value for the t statistic?
a. 38
b. 39
c. 40
d. 41
Answer:
Correct option: b 39.
Step-by-step explanation:
A one-sample (or one mean) t-test is applied to test whether the population-parameter is significantly different from some hypothetical value.
The degrees of freedom of the t-test is:
df = n - 1
It is provided that the sample size is, n = 40.
Compute the degrees of freedom as follows:
df = n - 1
= 40 - 1
= 39
Thus, the correct option is b.
You have 41 marbles in a bag. Inside the bag are 15 red marbles, 10 blue marbles, and
the rest are white. If you reach into the bag and randomly select a marble, then what is
the probability the selected marble will be red?

There are 41 marbles and 15 of them are red so you have a 15/41 chance to pick out a red as that is how many of them there are as compared to the total
Which equation shows the point-slope form of the line that passes through (3, 2) and has a slope of 1/3?
Answer:
Option 2: [tex]y - 2 = \frac{1}{3}(x-3)[/tex] is the correct answer.
Step-by-step explanation:
The equation of a line with given point(x1,y1) and slope m is given by:
[tex]y-y_1 = m(x-x_1)[/tex]
The line passes through (x1,y1)
Given
[tex](x_1,y_1) = (3,2)\\m = \frac{1}{3}[/tex]
=> x1 = 3
=> y1 = 2
Putting the values of x1, y1 and slope(m) in the point-slope form, the equation of line is:
[tex]y - 2 = \frac{1}{3}(x-3)[/tex]
Hence,
Option 2: [tex]y - 2 = \frac{1}{3}(x-3)[/tex] is the correct answer.

To find the result of the dilation, multiply each x and y coordinate by the scale factor, which in this case, is 1.5. I started out with the coordinate P, which had an original coordinate of (-2,1). In this case, I multiplied -2 by 1.5, and 1 by 1.5 to get (-3, 1.5). Since this is multiple choice, the only one with P as (-3, 1.5) is B, so we don't have to check the others.
The answer is B.
1) Apply dilation
2)Find each one x coordinate (x,y)
3) Find the y coordinate for each one
4) See which one matches your answers
