Enter your answer in the box.
Answer:
y = 8x
Step-by-step explanation:
The slope is 8, the y-intercept is 0. The slope-intercept form is written:
y = mx + b
So this situation would be written y = 8x + 0 or just y = 8x.

During final exam weeks, many college students exercise to fuel their study sessions. Data from a recent survey are shown in the Venn diagram. Let M be the event that the student exercises in the morning and let A be the event that the student exercises in the afternoon.
A Venn diagram titled exercise habits. One circle is labeled M, 0.25, the other circle is labeled A, 014, the shared area is labeled 0.37, and the outside area is labeled 0.24.
What is the probability that a randomly chosen college student exercises in the morning or afternoon?
0.37
0.39
0.62
0.76
Answer:
WARNING! .39 AND .76 IS WRONG.
THE PEOPLE ABOVE ARE INCORRECT.
THE ANSWER IS EITHER .37 OR .62
I believe the correct answer is .62 --> .25 + .37 = .62 . This also makes sense.

The probability that a randomly chosen college student exercises in the morning or afternoon are 0.37.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.
P(E) = Number of favorable outcomes / total number of outcomesFrom the given Venn diagram, we see that
Probability that the student exercises in the afternoon
P(A) = 0.14 + 0.37 = 0.51
Probability that the student exercises in the morning
P(M) = 0.25 + 0.37 = 0.61
Now, the probability that a randomly chosen college student exercises in the morning or afternoon
P(A ∩ M) = 0.37

Rewrite the function by completing the square. f(x)= x^2 +8x+4
Answer:
Please check the explanation.
Step-by-step explanation:
Given the function
[tex]f\left(x\right)=\:x^2\:+8x+4[/tex]
Let's rewrite the function by completing the square.
[tex]0=x^2+8x+4[/tex]
Subtract 4 from both sides
[tex]x^2+8x+4-4=0-4[/tex]
Simplify
[tex]x^2+8x=-4[/tex]
Rewrite in the form (x+a)²=b
[tex]x^2+8x=-4[/tex]
Rewrite in the form x²+2ax+a²
solve for a, 2ax = 8x
[tex]2ax=8x[/tex]
Divide both sides by 2x
[tex]\frac{2ax}{2x}=\frac{8x}{2x}[/tex]
simplify
[tex]a = 4[/tex]
Add a²=4² to both sides
[tex]x^2+8x+4^2=-4+4^2[/tex]
[tex]x^2+8x+4^2=12[/tex]
Apply perfect square formula
(a+b)²= a²+2ab+b²
[tex]\left(x+4\right)^2=12[/tex] ∵ [tex]x^2+8x+4^2=\left(x+4\right)^2[/tex]
Thus,
[tex]\left(x+4\right)^2=12[/tex]

Using confidence interval concepts, it is found that the margin of error is 5.
What is a confidence interval?A confidence interval (CI) is a range of estimates for an unknown parameter in frequentist statistics. A confidence interval has the format (a,b).
The margin of error is half the difference between the two bounds, that is:
M = ( b - a ) / 2
In this problem, the interval is (32, 42), hence, and the margin of error is:
M = ( 42 - 32 ) / 2 = 10 / 2 = 5
Therefore the margin of error is 5.

What is the length of the diagonal for the given rectangular prism to the nearest whole unit? A) 10 cm B) 11 cm 6 cm D) 13 cm
Hi there! :)
[tex]\large\boxed{\text{B. 11 cm.}}[/tex]
Begin by using Pythagorean theorem to solve for the length of the diagonal of the base:
a² + b² = c²
Use the length and width in the equation:
8² + 3² = c²
64 + 9 = c²
73 = c²
c ≈ 8.54 cm
Now, we can find the length of the diagonal of the prism using our calculated diagonal of the base and the height. Use the same equation:
(8.54)² + 7² = c²
73 + 49 = c²
122 = c²
√122 = c
c = 11.05 ≈ 11 cm. The correct answer is B.

Part A. Find the orthogonal trajectories of the family of curves. (Use C for any needed constant.)x2 + 2y2 = 17k2Part B. Find the orthogonal trajectories of the family of curves. (Use C for any needed constant.)y2 = 7kx3
Answer:
Following are the solution to the question:
Step-by-step explanation:
The objective is to find the orthogonal trajectory of the family curves:
[tex]x^2+2y^2=17k^2[/tex]
The family curves are: [tex]x^2 + 2y^2=17k^2[/tex]
Differentiate the equation with the respect of x.
[tex]\to x^2+2y^2=17k^2 \\\\\to 2x+4y \frac{dy}{dx} =0\\\\\to \frac{dy}{dx} =- \frac{2x}{4y}\\\\\to \frac{dy}{dx} =- \frac{x}{2y}[/tex]
The negative reciprocal is:
[tex]\to \frac{dy}{dx} =-\frac{1}{-\frac{x}{2y}}\\\\\to \frac{dy}{dx} = \frac{2y}{x}[/tex]
Integration of the above equation:
[tex]\to \frac{dy}{dx} = \frac{2y}{x} \\\\\to \int \frac{dy}{2y} = \int \frac{dx}{x}\\\\\to \frac{1}{2} \log y = \log x + \log C\\\\\to \log y = 2 \log x + 2\log C \\\\\to \log y = \log x^2 +\log C^2 \\\\\to y = Ax^2 \ \ \ \ \ \ \ \ \ (A=C^2)[/tex]
Hence, the orthogonal trajectory of the family of the curves [tex]x^2 + 2y^2 =17k^2 \ \ is \ \ y=Ax^2[/tex]

A The inequality 25m + 70 < 350 represents the fact that the student must save more than $11.20 each week to meet the goal.
B The inequality 25m + 70 < 350 represents the fact that the student must save more than $265 each week to meet the goal.
C The inequality 25m + 70 > 350 represents the fact that the student must save more than $265 each week to meet the goal.
D The inequality 25m + 70 > 350 represents the fact that the student must save more than $11.20 each week to meet the goal. ZEF 4
Answer:
A.) The inequality 25m + 70 < 350 represents the fact that the student must save more than $11.20 each week to meet the goal. I hope this helped u :)
Step-by-step explanation:
25 x 11.20 = 280
280+70=$350
but since the student wants to save more than $350 that's why it says the student must save MORE than $11.20 each week :)

A student sees a bird on top of a 12m high light pole. The student is standing 20m from the base of the pole. At what angle must the student incline her camera to take a picture of the bird?
Answer: 31 degrees
Step-by-step explanation:
The student must incline her camera at 31 degrees to take the picture of bird.
Angle of inclination:The angle of inclination of a line is the angle formed by the intersection of the line and x-axis.
According to the given question
height of pole = 12m
distance of student from the pole = 20m
Let the angle of inclination be x degrees.
therefore
for the angle of inclination
In ΔABC we have
[tex]tanx=\frac{12}{20}[/tex]
[tex]tanx=\frac{3}{5}[/tex]
[tex]x=tan^{-1} \frac{3}{5}[/tex]
[tex]x = tan^{-1}( 0.6)[/tex]
x = 31 degrees
Hence, the student must incline her camera at 31 degrees to take the picture of bird.
