The probability of success (p = 0.8) in each trial remains constant.
The trials are independent. This implies that the outcome from one trial has no effect on the outcome to be obtained from any other trial.
Each trial results in only two possible outcomes, labeled as the success ( Blue ) and failure ( Not blue ).
The experiment is performed a fixed number of times (n=12).
The X is a binomial random variable is 0.1329.
Given that,
An online spinner has two colored regions--blue and yellow.
According to the website, the probability that the spinner lands in the blue region on any spin is 0.80.
Assume for now that this claim is correct. Suppose we spin the spinner 12 times.
We have to determine,
X is a binomial random variable.
According to the question,
The experiment is performed a fixed number of times (n=12).Each trial results in only two possible outcomes, labeled as the success ( Blue ) and failure ( Not blue ).
The trials are independent. This implies that the outcome from one trial has no effect on the outcome to be obtained from any other trial.
The probability of success (p = 0.8) in each trial remains constant.
Therefore,
Number of trials: n = 12
Probability of success: p = 0.8
Let, x be the number of successes ( Blue ) in 12 trials.
The probability function of X:
[tex]P(X=x) = \ ^nC_x \times P^x \times (1-p)^{n-x}[/tex]
To find P(X = 8). Interpret this value in context.
At x = 8
[tex]P(X=8) = \ ^{12}C_2 \times (0.8)^{8} \times (1-0.08)^{12-8}\\\\P(X=8) = \dfrac{12!}{10!\ 2!} \times (0.8)^8\times (0.92)^4\\\\P(X=8) = 495 \times (0.167) \times (0.0016)\\\\P(X=8) = 0.1329[/tex]
Hence, The X is a binomial random variable is 0.1329.

solve the system of equations
Answer:
x= -8
y=7
Step-by-step explanation:
make it so the x's cancel out
to do this multiply the bottom equation by 2
2x+3y=5
2x+4y=12
subtract to cancel out the x
-y=-7
y=7
now substitute y into one of the equations(I'm going to do x+2y=6)

There are 178 more bikers than hikers if there are 676 people in the park total how many people are hikers?
Answer:
The total number of hikers are 427
Step-by-step explanation:
Let:
The number of bikers = x
The number of hikers = y
There are 178 more bikers than hikers
y = x + 178
if there are 676 people in the park total how many people are hikers?
Hence:
x + y = 676
we substitute x + 178 for y
x + x + 178 = 676
2x + 178 = 676
2x = 676 - 178
2x = 498
x = 498/2
x = 249
y =x + 178
y = 249 + 178
y = 427
Therefore:
The number of bikers = x = 249
The number of hikers = y = 427
The total number of hikers are 427

Two complementary angles have measures of `s` and `t`. If `t` is 9 less than twice `s`, what are the measures of each angle?
The value of s and t.
with work explaining.
Answer:
s measures 33° and t measures 57°.
Step-by-step explanation:
Since the two angles s and t are complementary, this implies that:
[tex]m\angle s+m\angle t=90[/tex]
We are given that t is 9 less than twice s. Hence:
[tex]m\angle t=2m\angle s-9[/tex]
We can substitute this into the first equation:
[tex]m\angle s+(2m\angle s-9)=90[/tex]
Solve for s. Combine like terms:
[tex]3m\angle s-9=90[/tex]
Adding 9 to both sides yields:
[tex]3m\angle s=99[/tex]
And dividing both sides by 3 gives us that:
[tex]m\angle s=33^\circ[/tex]
Returning to our second equation, we have:
[tex]m\angle t=2m\angle s-9[/tex]
So:
[tex]m\angle t=2(33)-9=66-9=57^\circ[/tex]
So, s measures 33° and t measures 57°.
Answer:
Two complementary angles have measures of `s` and `t`.
Hence, s+t=90°
`t` is 9 less than twice `s`, t=2s-9
According to the above problem,
→s+t=90
→s+2s-9=90
→3s=99
→s=99/3
→s=33
Therefore, the value of s=33°and t=2(33)-9 = 66-9 = 57°.help me pls !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Tickets to a freshman basketball game are $5 for students and $8 for adults. Last week 64 tickets were sold to the game for a total of $461. How many of each ticket were sold?
Answer:
Step-by-step explanation:
Let s be number of students and a be number of adults.
a + s = 64 -> 5a + 5s = 320
8a + 5s = 461
(8a + 5s) - (5a + 5s) = 461 - 320
3a = 141
a = 47
a + s = 64 -> s + 47 = 64 -> s = 17
Please thank, rate 5, and give brainliest if helpful!
Answer:
a + s = 64 -> 5a + 5s = 320
8a + 5s = 461
(8a + 5s) - (5a + 5s) = 461 - 320
3a = 141
a = 47
a + s = 64 -> s + 47 = 64 -> s = 17

(-1) 1001 integers .solve this
Answer:
-1
Step-by-step explanation:
(-1)^1001
= (-1)^1000 * (-1)^1
Since -1 raise to the power of an even number gives a positive value, then;
(-1)^1000 = 1
(-1)^1000 * (-1)^1 = 1 * -1
(-1)^1000 * (-1)^1 = -1
Hence (-1)^1001 = -1

3x + 4 = 2x + 10
3x-2x = 10-4
x = 6
3x + 4 = x + 12
3x-x = 12-4

x = 8/2 = 4
2x + 10 = x + 12
2x - x = 12-10
x = 2

In order to determine her pulse rate, June’s nurse counted 18 beats in her pulse in 15 seconds. At this rate, how many beats would she have in 60 seconds?
In this Problem you can use the Cross Multiplication.
If in 15 seconds the nurse counted 18 beats, so in 60 seconds she will count x beats.
15 seconds = 18 beats
60 seconds = x beats
You use the cross multiplication and multiply 60 by 18 and 15 by x, so you get:
15x = 60 * 18
15x = 1080
Then, you divide 15x and 1080 by 15 each, so you get:
x = 72
So, the Nurse counted 72 beats in 60 seconds

-10 - 6x > 26
+10 +10
-6x > 36
-6 -6
When you multiple/divide by a negative you have to flip the sign
x < -6
Answer:
c
Step-by-step explanation:
Given
- 10 - 6x > 26 ( add 10 to both sides )
- 6x > 36
Divide both sides by - 6, reversing the symbol as a result of dividing by a negative quantity.
x < - 6 → c
Consider the differential equation dy/dx = xy. Let y = f(x) be the function that satisfies the differential equation with initial condition f(1) = 1. Use Euler's Method, starting at x = 1 with a step size of .1, to approximate f(1.2).
Answer:
[tex]f(1.2)=1.221[/tex]
Step-by-step explanation:
From the question we are told that
[tex]dy/dx = xy[/tex]
Initial condition[tex]f(1) = 1.[/tex]
[tex]x = 1[/tex]
[tex]Step\ Size\ of\ 0.1[/tex]
Generally equation for [tex]y_1[/tex] is given mathematically as
[tex]f_0=F(1,1)=1[/tex]
Therefore
[tex]y_1=y_0+hf_0[/tex]
[tex]y_1=y_0+(0.1)(1)[/tex]
[tex]y_1=1.1[/tex]
Generally the approximation of the solution is mathematically given by
[tex]x=1+h\\x=1+0.1\\x=1.1[/tex]
[tex]y=1.1[/tex]
Generally the [tex]f_1[/tex] is mathematically given by
[tex]F_1=f(1.1,1.1)\\F_1=1.21[/tex]
Generally the [tex]y_2[/tex] is mathematically given by
[tex]y_2=y_1+hf_1\\y_2=1.1+0.121\\y_2=1.221[/tex]
Generally the approximation to the solution
at
[tex]y_2=1.221[/tex]
[tex]x_2=1.1+0.1\\x_2=1.2[/tex]
Therefore
[tex]f(1.2)=1.221[/tex]

intercept as that of the line represented by the equation y = 4x - 2?
F

y = 2x +
G
1
y = 4x -
2
Hy = 4x + 2
Jy = 2x - 2
Answer:
y = 2x-2
Step-by-step explanation:
Generally, we have the equation of a straight line as;
y = mx + b
where m is the slope and b is the y-intercept
For the second equation, we can see that the y-intercept value is -2
So using the slope 2, we write the complete equation as;
y = 2x - 2
