Answer:  y = 12x - 41

Step-by-step explanation:

The choices are not given, but you can figure this out.

Slope intercept form is y = mx + b

Substitute the y and x-values into the equation to calculate b, the y-intercept.

19 = 12(5) + b

19 = 60 + b

-60 + 19 =b

-41 = b

Write the equation with y and x, include the given slope and the calculated y-intercept:

y = 12x + 41

Answer:

Step-by-step explanation:

Slope of the given line = -7

parallel: slope = -7

perpendiculr: slope = -1/(-7) = 1/7

Answer:

How many minutes does it take to travel to school?

Step-by-step explanation:

A statistical question means you expect variability in the responses.

For instance, if you look at the first question, there's only 1 answer, so there's no variability. If you look at the second question, there's also only 1 answer.

How many minutes does it take to travel to school?

======================================================

Explanation:

Choice A is not a statistical question because we don't need to use statistics to find the answer. We simply count out the number of even numbers between 10 and 20. There's no need to draw a random sample of elements and do statistical analysis.

The same goes for choice B as well. There are 7 letters in this word and this value does not fluctuate/change.

Therefore we rule out choices A and B.

Choice C on the other hand has its answer vary depending on which person you ask. If you ask enough people, then you can find the average number of minutes, which is one tool to do statistics. This variable is considered a random variable (RV).

Answer:

brother gets 6 cards

sister gets 3 cards

he gets 15 cards

Step-by-step explanation:

this can be rewritten as

2x + x + 5x = 24

combine like terms

8x = 24

divide both sides by 8

x = 24/8

x = 3

now, multiply x by each part of the ratio.

his brother = 2 * 3 = 6

his sister = 1 * 3 = 3

himself = 5 * 3 = 15

Answer: 2.125

Step-by-step explanation: 3.4 x 5/8 = 2.125

Step-by-step explanation:

by graph method

x = -b/2a

b = 3, a = -9

x = -3/-18

x = 1/6

back to the equation to substitute

-9x + 3y = 12

-9(1/6) + 3y = 12

- 3/2 + 3y = 12

-3 + 6y = 24

6y = 27

y = 9/2

x = 1/6, y = 9/2

Answer:

$1.50

Step-by-step explanation:

Answer:

x = $1.50; The cost per pound of tomatoes is $1.50

Step-by-step explanation:

We can the cross method.

4 pounds = $6

1 pound   = x

4x = 6*1

4x=6

4x/4 = 6/4

x= 1 1/2 or $1.50

x = $1.50

The cost per pound of tomatoes is $1.50

Hope this helps!

Answer:

x^3+19x^2+119x+245

Step-by-step explanation:

The required value of function (f:g)(x) would be (x + 5) which is the ratio of function f(x) and g(x).

The quadratic equation is defined as a function containing the highest power of a variable is two.

Given that f(x) = x² + 12x + 35 and g(x) = x + 7

As per the question,

⇒ (f:g)(x) = (x² + 12x + 35) : (x + 7)

⇒ (f:g)(x) = (x² + 12x + 35) / (x + 7)

Solve the above quadratic equation, and we get

⇒ (f:g)(x) = (x² + 5x + 7x + 35) / (x + 7)

⇒ (f:g)(x) = x(x + 5) + 7(x + 5) / (x + 7)

⇒ (f:g)(x) = (x + 5)(x + 7) / (x + 7)

⇒ (f:g)(x) = (x + 5)

Therefore, the required value of function (f:g)(x) would be (x + 5).

Answer: 3.1 hours

Step-by-step explanation: Just took the quiz on edg.

  Water will reach a depth of 12 meters after 3.1 hours approximately.

   Function representing the level of water by 'y' and number of hours by 'x' is,

For y = 12 meters, (Substitute the value of y)

[tex]12=2.5\text{cos}(\frac{2\pi x}{12.5})+12[/tex]

[tex]12-12=2.5\text{cos}(\frac{2\pi x}{12.5})[/tex]

[tex]\text{cos}(\frac{2\pi x}{12.5})=0[/tex]

[tex]\frac{2\pi x}{12.5}=\frac{\pi }{2}[/tex]   (Since, [tex]\text{cos}(\frac{\pi }{2})=0[/tex])

[tex]\frac{\pi x}{12.5}=\frac{\pi }{4}[/tex]

[tex]x=\frac{\pi }{4}\times \frac{12.5}{\pi}[/tex]

[tex]x=3.125[/tex]

[tex]x\approx3.1[/tex] hours

    Therefore, water will reach a depth of 12 meters after 3.1 hours approximately.

Answer:

0.345

Step-by-step explanation:

Use binomial probability:

P = nCr pʳ qⁿ⁻ʳ

where n is the number of trials,

r is the number of successes,

p is the probability of success,

and q is the probability of failure (1−p).

n = 5, r = 2, p = 0.41, and q = 0.59.

P = ₅C₂ (0.41)² (0.59)⁵⁻²
