Answer:
14/885 or 1.58%
Step-by-step explanation:
In total, there are 60 marbles. The probability of drawing a blue marble the first time is 8/60. If you keep the one blue marble that was drawn, the total number of marbles in the bag is 59, and there are now 7 blue marbles. The probability of drawing a blue marble now is 7/59.
In order to find out the total probability of drawing two blue marbles in a row, you need to multiply these two fractions.
(8/60) x (7/59) = 56/3540 = 14/885 (approx. 1.58%)

The solution is
The equation of sets is given by n(A∪B) = n(A) + n(B) - n(A⋂B)
What is Set Theory Formula?
The set formula is given in general as n(A∪B) = n(A) + n(B) - n(A⋂B), where A and B are two sets and n(A∪B) shows the number of elements present in either A or B and n(A⋂B) shows the number of elements present in both A and B.
Given data ,
Let the equation be represented as A
The value of A is
n(A∪B) = n(A) + n(B) - n(A⋂B)
So , from the given Venn diagram , we get
The number of people who have been to the United States and Australia is given by A = 2
The number of people who have been to Australia and not been to United States is B = 5
The number of people who have not been to Australia but been to United States is C = 6
The number of people who have not been to Australia and not been to United States is D = 4
Hence , the equation is solved by sets

The x-intercept is the x value when y = 0. Another way to reword that is when the graph crosses the x-axis. The y-intercept is the y value when x = 0. Another way to reword that is when the graph crosses the y-axis.Step-by-step explanation:
According to the line on the graph, it passes the x-axis at x = -40 and it passes the y-axis at y = 15.
Therefore, our x-int is (-40, 0) and our y-int is (0, 15)

Answer: = 4y + 7z + 8
Answer:
7z+4y+8
Step-by-step explanation:
Collect the like terms so 12z-5z would be 7z, then since there is only 1 y term it would be 4y, and -7 + 15= 8

Step-by-step explanation:
Step 1: Define Equation
6(x - 1) = -72
Step 2: Solve for x
Divide 6 on both sides: x - 1 = -12Add 1 to both sides: x = -11Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 6(-11 - 1) = -72Subtract: 6(-12) = -72Multiply: -72 = -72Here we see that -72 does indeed equal -72.
∴ x = -11 is a solution to the equation.
Answer:
x = - 11
Step-by-step explanation:
Given
6(x - 1) = - 72 ← divide both sides by 6
x - 1 = - 12 ( add 1 to both sides )
x = - 11

**NEED THIS WITHIN 5 MINS** Stan’s employer pays for 45% of his annual health insurance premium of $4,567.00. Stan pays the remaining balance by having it deducted in equal amounts from his 26 paychecks throughout the calendar year. How much will Stan have deducted from each paycheck?
Answer:
$88.3
Step-by-step explanation:
Here 42% of annual health premium($5450)=*5450
=$2289
This amount is being paid by the company means it is deducted amount in one year.
One year has 26 paychecks so above amount divided by 26 is rebate amount in each paycheck.
Deducted amount=

Ms. Barcht Open a savings account with $50 and deposit $25 every week. Mrs. Greene save $75 every week. How many weeks will Mrs. Greene have more money in her account than ms. Bracht?
A. 25x+75>50
B. 75x=25x+50
C. 75x>25x+50
D. 75x<25x+50
Answer:
C
Step-by-step explanation:
Ms. Barcht's savings account can be modeled with the expression
50 + 25x
Mrs. Greene's savings account can be modeled with the expression
75x
Since the question is how many weeks Mrs. Greene will have more money than Ms. Bracht. we use an inequality to contain the all the solutions.
Mrs.Greene > Ms. Bracht
75x > 25x + 50
Answer:
The answer would be C. 75x>25x+50
Step-by-step explanation:
The answer would be C. because Ms. Barcht started with $50 and deposits $25 every week while Mrs. Greene saves $75 a week. 7 days is a week so lets multiply $25 x 2 (2 weeks). Ms. Barcht would have $100 by the end of 2 weeks and Mrs. Greene would have $150 by the end of 2 weeks because $75x2 is $150

A 20 foot ladder is leaning up against the side of a house. The construction worker who put it there followed the directions on the ladder's specifications which said to make sure the ladder was at least 8 feet away from the base of the wall to ensure safety. Say we want to re-word the directions and specify the angle of elevation of the ladder instead. What could the directions say about the angle of elevation?
Answer:
Keep the ladder at a 66 degree angle of elevation at most.
Step-by-step explanation:
Hypotenuse is 20 feet
Adjacent side is 8 feet
We use inverse cosine to find the angle
arccos(8/20) = 66.4 deg
log(x - 3) + log(x + 4) – log x = log 5

Answer:
a. 754cm³ (3 s.f.)
b. 415cm² (3 s.f.)
Step-by-step explanation:
Formulas (for easier reference):
Volume of cone: [tex]\pi[/tex]r²[tex]\frac{h}{3}[/tex]
Volume of hemisphere: [tex]\frac{2}{3}[/tex][tex]\pi[/tex]r³
Surface area of cone without base: [tex]\pi[/tex]rl
Surface area of hemisphere without base: 2[tex]\pi[/tex]r²
We can just apply the formulas for the question:
Volume of toy = ([tex]\pi[/tex] × 6² × [tex]\frac{8}{3}[/tex]) + ([tex]\frac{2}{3}[/tex] × [tex]\pi[/tex] 6³)
= 96[tex]\pi[/tex] + 144[tex]\pi[/tex]
= 240[tex]\pi[/tex]
= 754cm³ (3 s.f.)
Surface area of toy = ([tex]\pi[/tex] × 6 × 10) + (2 × [tex]\pi[/tex] × 6²)
= 60[tex]\pi[/tex] + 72[tex]\pi[/tex]
= 132[tex]\pi[/tex]
= 415cm² (3 s.f.)

a. When x = -1, what is the value of y?
Continue on the following page.
b. When y = 7, what is the value of x?
c. What is the y-intercept of the graph?
d. What is the x-intercept of the graph?
e. What is the slope of the line?
f. What is the equation of the line?
Answer:
a. y = 3
b. x = 1
c. y-intercept = 5
d. x-intercept = -2.5
e. 2
f. y = 2x + 5
Step-by-step explanation:
Based on the graph, we can see the point where x is -1, y = 3.
Based on the graph, we can see the point where y = 7, x = 1.
Based on the graph, we can see the y-intercept is 5.
Based on the graph, we can see the x-intercept is -2.5.
To calculate the slope of the line, I will be using the points (-1, 3) and (0, 5).
Slope = [tex]\frac{rise}{run}[/tex]
= [tex]\frac{5-3}{0-(-1)}[/tex]
= [tex]\frac{2}{1}[/tex]
= 2
The equation of a line is: y = mx + c where m is the slope and c is the y-intercept. Thus, the equation of the line in this case is: y = 2x + 5

Answer:
x = - 3
Step-by-step explanation:
Given
3(x - 6) + 6 = 5x - 6 ← distribute and simplify left side
3x - 18 + 6 = 5x - 6
3x - 12 = 5x - 6 ( subtract 5x from both sides )
- 2x - 12 = - 6 ( add 12 to both sides )
- 2x = 6 ( divide both sides by - 2 )
x = - 3
