Answer:
169 students
Step-by-step explanation:
From the above question:
Total number of students surveyed = 260
Percentage of students that their favorite colour is red = 65%
Hence: The number of students that their favorite color is red is calculated as:
= 65% × 260
= 65/100 × 260 students
= 169 students
The number of students that their favorite color is red is 169 students

please help and show work
Step-by-step explanation:
Since PT = 2PM and AR = 2AD,
The midsegment MD must be the average of PA and TR:
Therefore we have
2(20x + 4) = 10 + (34x + 16)
=> 40x + 8 = 34x + 26
=> 6x = 18
=> x = 3
Hence length of MD
= 40(3) + 8 = 128.

A 14 1/2 foot by 30 foot concrete wall is to be built using concrete blocks. Find the area of the wall
Answer:
The area of the wall is 435 square foot.
Step-by-step explanation:
a) Data and Calculations:
One side of the wall (height) = 14 1/2 foot = 14.5 foot
The second side of the wall (length) = 30 foot
The area of the wall = height * length
= 14.5 * 30
= 435 square foot
b) The area of a wall is usually obtained by Height x Length. It uses the same standard formula of (Length) x (Width) for calculating the area of any surface, only that this time, the width changes to height because of the nature of the wall.

Ron solved the equation (2/3)r = 12 by multiplying both sides by 2/3 and he got r = 8. Explain the error that Ron made and then find the correct value for r
Answer:
Ron multiplied with the wrong number. He should have multiplied with 3/2 (the reciprocal of 2/3), which would have made the 2/3 a 1, thus isolating the r.
r = 18
Step-by-step explanation:
(2/3)(3/2)r = 12
r = 12(3/2)
r = 18
What is the equation of the line in slope-intercept form?
Answer:
[tex]\bold{y=-\frac12x}[/tex]
Step-by-step explanation:
Slope-intercept form: y = mx + b
The line intersect Y-axis at y=0 so b = 0
The line passses through points (0, 0) and (2, -1), so the slope:
[tex]m=\dfrac{-1-0}{2-0}=-\dfrac12[/tex]
Therefore the equation:
[tex]y=-\frac12x+0\\\\y=-\frac12x[/tex]

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 and let x = the number of times it lands in the blue region.
Explain why X is a binomial random variable.
Answer:
Skewed Left :)
Step-by-step explanation:
Correct on Edge 2021
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.

Solving for x on the question - 2x + 3y = 32 | Answer : x = [tex]\frac{-3}{2}[/tex]⁻y + 16Solving for y on the question - 2x + 3y = 32 | Answer : y = [tex]\frac{-2}{3}[/tex]x + [tex]\frac{32}{3}[/tex] Solving for x on question - 5x - 4y = -81 |Answer : x = [tex]\frac{4}{5}[/tex]y + [tex]\frac{-81}{5}[/tex]
Solving for y on question - 5x - 4y = -81 |Answer : y = [tex]\frac{-5}{4}[/tex]x + [tex]\frac{81}{4}[/tex]Step-by-step explanation:
(Solving for x on question - 2x + 3y = 32)
2x + 3y = 32
Step 1: Add -3y to both sides.
2x + 3y + −3y = 32 + −3y
2x = −3y + 32
Step 2: Divide both sides by 2.
[tex]\frac{2x}{2}[/tex] = [tex]\frac{-3y+32}{2}[/tex]
x = [tex]\frac{-3}{2}[/tex]⁻y + 16
(Solving for y on question - 2x + 3y = 32)
2x + 3y = 32
Step 1: Add -2x to both sides.
2x + 3y + −2x = 32+ −2x
3y = −2x + 32
Step 2: Divide both sides by 3.
[tex]\frac{3y}{3}[/tex] = [tex]\frac{-2x+32}{3}[/tex]
y = [tex]\frac{-2}{3}[/tex]x + [tex]\frac{32}{3}[/tex]
(Solving for x on question - 5x - 4y = -81)
5x − 4y = −81
Step 1: Add 4y to both sides.
5x − 4y + 4y = −81 + 4y
5x = 4y − 81
Step 2: Divide both sides by 5.
[tex]\frac{5x}{5}[/tex] = [tex]\frac{4y-81}{5}[/tex]
x = [tex]\frac{4}{5}[/tex]y + [tex]\frac{-81}{5}[/tex]
(Solving for y on question - 5x - 4y = -81 )
5x − 4y = −81
Step 1: Add -5x to both sides.
5x − 4y + −5x = −81 + −5x
−4y = −5x − 81
Step 2: Divide both sides by -4.
[tex]\frac{-4y}{-4}[/tex] = [tex]\frac{-5x-81}{-4}[/tex]
y = [tex]\frac{-5}{4}[/tex]x + [tex]\frac{81}{4}[/tex]
