Missing Part:
a. A red ball is drawn
b. A white ball is drawn
Answer:
a. [tex]P(Red) = 0.4375[/tex]
b. [tex]P(White) = 0.3125[/tex]
Step-by-step explanation:
Given
[tex]Red = 7[/tex]
[tex]White = 5[/tex]
[tex]Yellow = 4[/tex]
First, we need to calculate the total
[tex]Total = Red + White + Yellow[/tex]
[tex]Total = 7+5+4[/tex]
[tex]Total = 16[/tex]
Solving (a): Probability of Red.
This is calculated by dividing number of red balls by the total
So:
[tex]P(Red) = \frac{Red}{Total}[/tex]
[tex]P(Red) = \frac{7}{16}[/tex]
[tex]P(Red) = 0.4375[/tex]
Solving (a): Probability of White.
This is calculated by dividing number of white balls by the total
So:
[tex]P(White) = \frac{White}{Total}[/tex]
[tex]P(White) = \frac{5}{16}[/tex]
[tex]P(White) = 0.3125[/tex]
8. Write the equation in Slope-Intercept Form with the following, information:
Remember, plug into point-slope, y - y, = m(x - x,), then solve down I
Passes through (7, 4) with a slope of -3
The slope-intercept equation of the given line is 3x + y = 25
Slope-intercept is one of the special forms of linear equations where we can find the slope-intercept of any point with its coordinates and its slope.
The line is passing through the point(x₁,y₁) = (7,4)
The slope of the line line(m) = -3
Slope-intercept equation
y-y₁ = m( x- x₁)
Where (x₁,y₁) is (7,4) and Slope,m is -3
Let us substitute these values in the slope-intercept equation, It becomes
y - 4 = -3(x - 7)
y - 4 = -3x + 21
3x + y = 21 + 4
3x + y = 25
which is the slope-intercept equation of the points (7,4) and slope -3

Question 5 Multiple Choice Worth 1 points) (04.05 MC) Determine if the ordered pair (-1 , -5) is a solution to the inequality y≤-3/4-1
No, because (-1. 5) is above the line
Yes, because (-1, -5) is below the line
No, because (-1, 5) is on the line
Yes, because 1-1, 5) is on the line
Answer:
(-1, -5) satisfies the inequality and will be the solution to the inequality.
From the attached figure, it is clear that (-1, -5) is below the line.
Therefore, the correct option is:
''Yes, because 1-1, 5) is on the line''.
Step-by-step explanation:
Given the inequality
[tex]y\le -\frac{3}{4}x-1[/tex]
substituting (-1, -5) to check whether it satisfies the inequality or not
[tex]-5\le \:-\frac{3}{4}\left(-1\right)-1[/tex]
[tex]-5\:\le \:\frac{3}{4}-1[/tex]
[tex]-5\:\le -\frac{1}{4}[/tex]
TRUE
Thus, (-1, -5) satisfies the inequality and will be the solution to the inequality.
From the attached figure, it is clear that (-1, -5) is below the line.
Therefore, the correct option is:
''Yes, because 1-1, 5) is on the line''.
5/8 and 3/4 I need an answer pleaseee
I'm not sure what you mean but I'll provide both.
5/8 + 3/4
11/8 or 1 3/8.
The common denominator of 5/8 and 3/4 is 8. 3/4 with a denominator of 8 would be 6/8.
5/8 + 6/8 = 11/8 or 1 3/8.
5/8 × 3/4
15/32.
Multiply the numerator by the numerator and the denominator by the denominator.
5 times 3 is 15 and 8 times 4 is 32.
So you get 15/32. This cannot be simplified.
Factor completely
81x^12 - 1
Answer:
81x^(2)-1
Step-by-step explanation:
Rewrite 81^(2) as (9x)^(2)
Rewrite 1 as 1^(2)
Since they are perfect squares , factor using the perfect squares formula
(9x + 1) (9x - 1)
x + 8 + 2x <= 2x + 13
Answer:
X = 15
Step-by-step explanation:
We move all terms to the left:
x+8+2x-(2x+13)=0
We add all the numbers together, and all the variables:
3x-(2x+13)+8=0
We get rid of parentheses:
3x-2x-13+8=0
We add all the numbers together, and all the variables:
x-5=0
We move all terms containing x to the left, all other terms to the right:

A) 5n - 3
B) 5 - 35
C) 3n - 5
D) 3 - 5
Answer:
A)
Step-by-step explanation:
The correct expression which represents ''3 less than 5 times a number'' would be,
A) 5n - 3
Mathematical expression is defined as the collection of numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that,
A mathematical expression is,
''3 less than 5 times a number''
Let us assume that,
A number = x
Hence, the expression to represent ''3 less than 5 times a number'' is,
⇒ (5 × n) - 3
⇒ 5n - 3
So, the correct option is,
A) 5n - 3

Find the sample variance and standard deviation
19,12,6,7,11
Thank you
Answer:
Variance: 26.5
Standard Deviation: 5.1478150704935
Step-by-step explanation:
First, Add up all of the numbers: 6 + 7 + 11 + 12 + 19 = 55
Square the total, and then divided the number of items in the data set55 x 55 = 3025
3025 / 5 = 605
Take your set of original numbers from step 1, squared them individually this time, and added them all up:(6 x 6) + (7 x 7) + (11 x 11) + (12 x 12) + (19 x 19) = 711
Subtract the amount in step 2 from the amount in step 3:711 - 605 = 106
Subtract 1 from the number of items in my data set:5 - 1 = 4
Divide the number in step 4 by the number in step 5:106 / 4 = 26.5
Finally, take the square root of the number from step 6 (the variance),
√(26.5) = 5.1478150704935

(q or)(2) =

?
Answer:
(r o g)(2) = 4
(q o r)(2) = 14
Step-by-step explanation:
Given
[tex]g(x) = x^2 + 5[/tex]
[tex]r(x) = \sqrt{x + 7}[/tex]
Solving (a): (r o q)(2)
In function:
(r o g)(x) = r(g(x))
So, first we calculate g(2)
[tex]g(x) = x^2 + 5[/tex]
[tex]g(2) = 2^2 + 5[/tex]
[tex]g(2) = 4 + 5[/tex]
[tex]g(2) = 9[/tex]
Next, we calculate r(g(2))
Substitute 9 for g(2)in r(g(2))
r(q(2)) = r(9)
This gives:
[tex]r(x) = \sqrt{x + 7}[/tex]
[tex]r(9) = \sqrt{9 +7{[/tex]
[tex]r(9) = \sqrt{16}[/tex]{
[tex]r(9) = 4[/tex]
Hence:
(r o g)(2) = 4
Solving (b): (q o r)(2)
So, first we calculate r(2)
[tex]r(x) = \sqrt{x + 7}[/tex]
[tex]r(2) = \sqrt{2 + 7}[/tex]
[tex]r(2) = \sqrt{9}[/tex]
[tex]r(2) = 3[/tex]
Next, we calculate g(r(2))
Substitute 3 for r(2)in g(r(2))
g(r(2)) = g(3)
[tex]g(x) = x^2 + 5[/tex]
[tex]g(3) = 3^2 + 5[/tex]
[tex]g(3) = 9 + 5[/tex]
[tex]g(3) = 14[/tex]
Hence:
(q o r)(2) = 14
