Answer:
c. 0.17
Step-by-step explanation:
The bag have 4 + 2 + 6 = 12 balls.
There are 2 red marbles, in 12, the probability to take one red is 2/12. Is important to remember that the first marble was replaced before the second outcome, so the chance for the second is also 2/12:
2/12 = 1/6 = 0.1666 ≈ 0.17
The expected value of the random variable that assigns the number of red marbles to each outcome is 0.17.
What is the probability?Probability is used to estimate how likely an event would happen. The probability the event occurs with certainty is 1 and the probability that the event does not occur with certainty is 0.
Expected value = number of red marbles / total number of marbles
2/12 = 0.17

What pair of angles must have the same measure?I'll give brainliest if its correct.
Answer:
[tex]\text{(C) }\angle 2\text{ and }\angle 7[/tex]
Step-by-step explanation:
Angle 2 corresponds with angle 6 and since all corresponding angles are equal, [tex]\angle 2=\angle 6[/tex]. Angle 6 and angle 7 happen to be vertical angles (opposite side of an intersection of two lines). Since all vertical angles are also equal, [tex]\angle 6=\angle 7[/tex] and by substitution, we have: [tex]\implies \boxed{\text{(C) }\angle 2\text{ and }\angle 7}[/tex]

Answer:
Tan <A = 4/3
Cos <A = 3/5
Sin <A = 4/5
Step-by-step explanation:
From the diagram given
Hypotenuse AB = 10
Adjacent = 6
Opposite = 8 (side facingc<A)
According to SOH CAH TOA
Tan <A = Opposite/adjacent
Tan <A = BC/AC
Tan <A = 8/6
Tan <A = 4/3
For Cos <A;
Cos <A = adj/hyp
Cos <A = 6/10
Cos <A = 3/5
For sin<A:
Sin <A = opp/hyp
Sin <A = 8/10
Sin <A = 4/5

What is the decay factor of the exponential function
represented by the table?
Given:
The table of values of an exponential function.
To find:
The decay factor of the exponential function.
Solution:
The general form of an exponential function is:
[tex]y=ab^x[/tex] ...(i)
Where, a is the initial value and [tex]0<b<1[/tex] is the decay factor and [tex]b>1[/tex] is the growth factor.
The exponential function passes through the point (0,6). Substituting [tex]x=0,y=6[/tex] in (i), we get
[tex]6=ab^0[/tex]
[tex]6=a(1)[/tex]
[tex]6=a[/tex]
The exponential function passes through the point (1,2). Substituting [tex]x=1,y=2,a=6[/tex] in (i), we get
[tex]2=6(b)^1[/tex]
[tex]2=6b[/tex]
[tex]\dfrac{2}{6}=b[/tex]
[tex]\dfrac{1}{3}=b[/tex]
Here, [tex]b=\dfrac{1}{3}[/tex] lies between 0 and 1. Therefore, the decay factor of the given exponential function is [tex]\dfrac{1}{3}[/tex].
Hence, the correct option is A.

What is the equation of the line that is parallel to the line x = -2 and passes through the point (5.4)?
Lines parallel to each others only occur when two slopes of equations are same. The definition of parallel lines is:
[tex] \large \boxed{m_1 = m_2}[/tex]
We are given the equation of a line which is x = -2. For x = a, the equation forms a verical line and has an undefined slope. These below are basic that you may need to learn when learning about the line graph:
y = a —> horizontal line; slope is 0.x = a —> vertical line; slope is undefined.For y = a, any a-values would have same x-values. For example, if we are given y = 2 then any domains or x-values can have the range of 2.For x = a, any a-values would have same y-values or range.Back to the question. We want to find the equation of a line that is parallel to the line x = -2 and passes through (5,4) point. Recall the definition of parallel line that both slopes of equations must equal. Since x = a for any a-values would give an undefined slope. That means our parallel would be x = b.
Because the line passes through (5,4) - for any a-values from x = a would give out the set of all real numbers for range. Therefore the equation of a line is x = 5.
Answer
The equation of a line that is parallel to x = -2 and passes through (5,4) is x = 5.I hope this helps! If you have any doubts or questions, don't hestitate to ask in comment! Good luck on your assignment and have a great day!
8x+20y=-120 as slope
Answer:
y = -2/5x -6
slope is -2/5
y intercept -6
Step-by-step explanation:
8x+20y=-120
Slope intercept form is y = mx+b where m is the slope and b is the y intercept
Subtract 8x from each side
8x -8x+20y= -8x-120
20y = -8x - 120
Divide by 20
20y/20 = -8x/20 -120/20
y = -2/5x -6
You invest $10,200 in an account that compounds continuously at an annual percent interest rate of 6.25%. How long does it take to double your money?
Answer:
11.09 years
Step-by-step explanation:
Given data
Principal P= $10200
Rate= 6.25%
Double the principal A = $20,400
The expression for the time taken is
t= ln(A/P)/r
t= ln(20400/10200)/0.0625
t= ln(2)/0.0625
t= 0.69314/0.0625
t= 11.09024 years
Hence the number of years is 11.09 years
Describe the behavior of the function h around its vertical asymptote at x=-6.
Answer:
B
Step-by-step explanation:
One good way to look at this is to graph both polynomials, as shown in the picture. A tip to help graph is to factor it out and work from there. For example, in x²+14x+48, we can gather that (x+6)(x+8) is the same thing, and it is easier to then graph it. Similarly, for x²+12x+36, we can factor it out as (x+6)² .
When x²+12x+36 approaches 6, it is getting really close to 0, but it stays positive. When x²+14x+48 approaches 6 from the negative side, it is also getting close to 0, but it's negative. When x²+14x+48 approaches 6 from the positive side, it is positive.
Therefore, on the negative side, there is one positive and one negative (dividing a negative by a positive is negative, and a positive by a negative is also negative) , and on the positive side, there are two positives, forming one answer.The answer is therefore B

Cameron sponsored a fundraiser that 582 people attended. He raised 6,480. He charged $15 for balcony seats and $10 for ground seats. How many people bought balcony seats (b) and how many bought ground seats (g)?
15b + 10g = 6,480
b + g = 582
Answer:
132 people bought balcony seats and 450 people bought ground seats.
Step-by-step explanation:
We want to solve the system of equations:
[tex]\left\{ \begin{array}{ll} 15b+10g=6480 \\ b+g=582 \end{array} \right[/tex]
We can solve this by using substitution. From the second equation, we can subtract b from both sides:
[tex]g=582-b[/tex]
In the first equation, we can divide both sides by five:
[tex]3b+2g=1296[/tex]
Substitute:
[tex]3b+2(582-b)=1296[/tex]
Distribute:
[tex]3b+1164-2b=1296[/tex]
Simplify:
[tex]b+1164=1296[/tex]
Solve for b:
[tex]b=132[/tex]
Using the modified equation again, substitute:
[tex]g=582-(132)[/tex]
Evaluate:
[tex]g=450[/tex]
Therefore, 132 people bought balcony seats and 450 people bought ground seats.

Which is the length of the building's wall brace?
A. 14.45 m
B. 17 m
C. 23 m
D. 49 m
E. 189 m
Answer:
A) 14.45 m is the answerrrerreer
Answer:
17m
Step-by-step explanation:
We can use the Pythagorean theorem
a^2+b^2= c^2 where a and b are the legs and c is the hypotenuse
8^2 + 15^2 = c^2
64+ 225 = c^2
289 = c^2
Taking the square root of each side
sqrt(289) = sqrt(c^2)
17 =c
