Answer:
The probability that the all three votes are Democrats
P(X=3) = 0.1038
Step-by-step explanation:
Step(i):-
Given that the all voters are democrats
The probability that the all voters are democrats
p = 47% =0.47
q = 1-p =1-0.47 = 0.53
Step(ii):-
Let 'X' be the random variable in binomial distribution
[tex]P(X=r) = n_{C_{r} } p^{r} q^{n-r}[/tex]
The probability that the all three votes are Democrats
P(X=3) = 0.1038
n=3 and r=3
[tex]P(X=3) = 3_{C_{3} } (0.47)^{3} (0.53)^{3-3}[/tex]
[tex]P(X=3) = 1 (0.47)^{3}[/tex]
P(X=3) = 0.1038
Final answer:-
The probability that the all three votes are Democrats
P(X=3) = 0.1038

Step-by-step explanation:
☆9x - 15 is congruent to 7x + 5, meaning they equal the same. This is because they are vertical to each other
☆The equation would be a 9x - 15 = 7x + 5.
☆Let's solve it!
[tex] \: \: \: \: \: \: \: \: \: 9x - 15 = 7x + 5 \\ \frac{ - 7x \: \: \: \: \: \: \: = - 7x}{2x - 15 = 5} \\ \frac{ \: \: \: \: \: \: \: \: \: \: + 15 = + 15}{ \frac{2x}{2} = \frac{20}{2} } \\ \\ x = 10[/tex]
-------
☆2x + 15 and x are complementary angles, meaning they equal 90ndegrees together. This is because they lie on a right angle.
☆The equation would be: 2x + 15 + x = 90.
☆Let's solve it!
[tex]2x + 15 + x = 90 \\ 3x + 15 = 90 \\ \frac{ \: \: \: \: \: \: \: \: \: - 15 = - 15}{ \frac{3x}{3} = \frac{75}{3} } \\ \\ x = 25[/tex]

3. 11 = 2x + 1
Answer:
1. x = 3
2.x = 6
3. x = 5
I hope this helps you :D
To solve for variables, we start by isolating the variable term and then solve for the variable. The values of x in the given equations are 3, 6 and 5, respectively.
Equation (1)
[tex]17 = 5x + 2[/tex]
Collect like terms
[tex]5x = 17 -2[/tex]
[tex]5x = 15[/tex]
Divide both sides by 5
[tex]x =3[/tex]
Equation (2)
[tex]2x^2 - 5 = 3x^2 - 12x + 31[/tex]
Collect like terms
[tex]3x^2 - 2x^2 - 12x + 31 +5=0[/tex]
[tex]x^2 - 12x + 36=0[/tex]
Expand
[tex]x^2 - 6x - 6x + 36=0[/tex]
Factorize
[tex]x(x - 6) - 6(x -6)=0[/tex]
Factor out x - 6
[tex](x - 6)(x -6)=0[/tex]
This means that:
[tex]x -6=0[/tex]
Solve for x
[tex]x = 6[/tex]
Equation (3):
[tex]11 = 2x + 1[/tex]
Collect like terms
[tex]2x = 11-1[/tex]
[tex]2x = 10[/tex]
Divide both sides by 2
[tex]x =5[/tex]
Hence, the values of x in the given equations are 3, 6 and 5.

1. 2/25 46%
2. 23/50 70%
3. 14/20 0.08
4. 90% 0.9
Answer:
1. 2/25 = 0.08 = 80%
2. 23/50 = 0.46 = 46%
3. 14/20 = 0.70 = 70%
4. 90% = 90/100 = 0.9
Step-by-step explanation:
To find the right match, we would divide the fraction on the left and select the value that is the same with the answer gotten.
1. 2/25 = 0.08 = 80%
2. 23/50 = 0.46 = 46%
3. 14/20 = 0.70 = 70%

Tyler was at the amusement park. He walked at a steady pace from the ticket booth to the bumper

The point on the graph shows his
arrival at the bumper cars. What do
the coordinates of the point tell us
about the situation?
What does the point (0,0) mean in
this situation?
What is the constant of
proportionality for the relationship
between time and distance? What
does it tell you about Tyler's walk?
Where do you see it in the graph?
9514 1404 393
Answer:
a) It took 40 seconds to go 50 meters from the ticket booth
b) Tyler started at the ticket booth
c) k = 5/4
d) Tyler walked at the rate of 1.25 meters per second
e) The constant of proportionality is the slope of the line from (0, 0) to (40, 50). It is not shown on the graph.
Step-by-step explanation:
a) The axis labels on the graph tell you that 40 represents the number of seconds of elapsed time, and 50 represents the number of meters from the ticket booth. With the information in the problem statement, the coordinates (40, 50) tell us it took Tyler 40 seconds to walk 50 meters from the ticket booth to the bumper cars.
__
b) The point (0, 0) tells us that Tyler started counting time when he left the ticket booth.
__
c) The constant of proportionality is the ratio of the second coordinate to the first. The constant of proportionality is 50/40 = 5/4 = 1.25. (Its units are meters per second.)
__
d) The constant of proportionality tells us that Tyler's steady pace was 1.25 meters per second.
__
e) The constant of proportionality is not shown on the graph. It is the slope of a line between the origin and the point (40, 50).
A particle moves along the x-axis so that at time t≥0t\ge 0t≥0 its position is given by x(t)=−t3+6t2−9t+42.x(t)=-t^3+6t^2-9t+42.x(t)=−t3+6t2−9t+42. Determine the total distance traveled by the particle from 0≤t≤4.0\le t \le 4.0≤t≤4.
Answer: 4 units
Step-by-step explanation:
The given position function: [tex]x(t)=-t^3+6t^2-9t+42.[/tex], where t≥0.
To determine: Total distance traveled by the particle from 0≤ t ≤ 4.0.
At t=0,
[tex]x(0)=-(0)^3+6(0)^2-9(0)+42=42\\[/tex]
At, t=4,
[tex]x(4)=-(4)^3+6(4)^2-9(4)+42\\\\=-64+6(16)-36+42=38[/tex]
Total distance traveled by the particle from 0≤ t ≤ 4.0 = |42-38| units
= 4 units
Hence, the distance traveled by the particle from 0≤t≤4.0 is 4 units.

Katherine D’Ann is planning to finance her college education by selling programs at the football games for State University. There is a fixed cost of $400 for printing these programs, and the variable cost is $3. There is also a $1,000 fee that is paid to the university for the right to sell these programs. If Katherine was able to sell programs for $5 each, how many would she have to sell in order to break even?
Answer:
700 programs
Step-by-step explanation:
Given that :
Fixed cost = $400
Variable cost = $3 per program
Right to sell fee = $1000
Sales price per program = $5
Let number of programs sold = x
In other to break even, expense = revenue
(Fixed cost + variable cost per program + right to sell fee) = sales price per program
(400 + 3x + 1000) = 5x
1400 + 3x = 5x
1400 = 5x - 3x
1400 = 2x
1400 / 2 = x
x = 700
Number of programs to be sold in other to break even = 700

On a treasure map, a X is placed at point (9, -7). if the pirates are currently on point (9,3), how many units away are they?
Answer:
They are 10 units away from the treasure
Step-by-step explanation:
Notice that the points (9, -7) and (9, 3) are both located at the same x-value (9) while their y-values are in one case 3 units above the x-axis, and in the other 7 units BELOW the x-axis. Therefore thy differ by 3 - (-7) units , which totals 10 units.

Compute 292,000 divide 100.
The division 292,000 divide 100. results to 2920.
What is Division?Repetitive subtraction is the process of division. It is the multiplication operation's opposite. It is described as the process of creating equitable groups. When dividing numbers, we divide a larger number down into smaller ones such that the larger number obtained will be equal to the multiplication of the smaller numbers.
Given:
292,000 divide 100.
We know division with zero in the denominator is different and easy.
As, 292000 have three and 100 have two zeroes.
So, the two zero of hundred cancels out the two zeroes of 292000.
So, 292000/ 100
= 2920
Hence, the division results to 2920.

How is a constant term different from a variable term
for an expression that represents a real-world situation?
Answer:
Constants are the terms in the algebraic expression that contain only numbers. That is, they're the termswithout variables. We call them constants because their value never changes, since there are no variablesin the term that can change its value.
