Is the point (4,11) a solution to the following system of equations? How do you know?
y=2x+14
y=3x−5

Answer:

The corn plant grew by 11.17 inches during week 2.

Step-by-step explanation:

7 and 1/3 inches tall at the end of Week 1.

The height at the end of week 1, as a simple fraction, is:

[tex]7 + \frac{1}{3} = \frac{3*7 + 1}{3} = \frac{22}{3}[/tex]

The corn plant was 18 1/2 inches tall at the end of Week 2.

At the end of week 2, the height will be of:

[tex]18 + \frac{1}{2} = \frac{18*2+1}{2} = \frac{37}{2}[/tex]

How many inches did the corn plant grow during Week 2?

Height at the end of week 2 subtracted by the height at the end of week 1. So

[tex]\frac{37}{2} - \frac{22}{3} = \frac{3*37-2*22}{6} = \frac{67}{6} = 11.17[/tex]

The corn plant grew by 11.17 inches during week 2.

Answer:

55°

Step-by-step explanation:

In triangle BAC, angle C =

180° - 90° - 70°

Angle C = 20°

In triangle DAB, angle C =

180° - 90° - 55°

Angle C = 35°

Add both angles

20° + 35° = 55°

Answer:

x=9

Step-by-step explanation:

This equation, in my use, is more of a guess-and-check. I noticed 15 divides nicely into 135 and then punched that into my calculator. 135/15 = 9. And when you add 9 and 6 together, it makes 15. Therefore, x must equal 9.

Answer:

0.9945 = 99.45% probability that the student answers at most four questions correctly

Step-by-step explanation:

For each question, there are only two possible outcomes. Either the student answers correctly, or he/she does not. The probability of the student answering a question correctly is independent of any other question. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

A quiz consists of six multiple choice questions.

This means that [tex]n = 6[/tex]

Each question has four choices. Student guesses randomly.

This means that [tex]p = \frac{1}{4}[/tex]

What is the probability that the student answers at most four questions correctly?

This is:

[tex]P(X \leq 4) = 1 - P(X > 4)[/tex]

In which

[tex]P(X > 4) = P(X = 5) + P(X = 6)[/tex]. So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 5) = C_{6,5}.(0.25)^{5}.(0.75)^{1} = 0.0053[/tex]

[tex]P(X = 6) = C_{6,6}.(0.25)^{6}.(0.75)^{0} = 0.0002[/tex]

[tex]P(X > 4) = P(X = 5) + P(X = 6) = 0.0053 + 0.0002 = 0.0055[/tex]

[tex]P(X \leq 4) = 1 - P(X > 4) = 1 - 0.0055 = 0.9945[/tex]

0.9945 = 99.45% probability that the student answers at most four questions correctly

Answer:

Step-by-step explanation:

Remember the that the right side is positive and left side is negative so your starting at the midpoint i dont know how to explain it in words but look up some videos. its rise over run so for the left image u rise up 1 and u go over 2 so it will be 1 over 2 meaning 1/2. for the image on the right you go to the left(run) which is negative so its -1 up 3 cause u rise 3! its -1/3  i know its not the best explaining but I hope this helps!

Answer:

Jocelyn's plane travelled 3650 miles.

Step-by-step explanation:

mph stands for miles per hour.

Let's set up an equation.

total miles = speed(hours)

Jocelyn's plane travelled 500 mph for 7.3 hours.

total miles = 500(7.3)

Multiply.

total miles = 3650

Jocelyn's plane travelled 3650 miles.

Hope this helps!

Answer:

x=  12.528

*rounded is 12.53 or 12.5

Step-by-step explanation:

7.3 ^2 + x^2 = 14.5^2

53.29 + x^2 = 210.25

-53.29            -53.29

x^2= 156.96

x= 12.528

Answer:

  the y-intercepts differ

Step-by-step explanation:

The x-coefficient is the same for each function, so parallel lines are described. The function g(x) has a y-intercept of -4; f(x) has a y-intercept of 0.

The graphs differ in their intercepts.

__

Additional comment

g(x) can be considered to be a translation downward of f(x) by 4 units. The same graph of g(x) can be obtained by translating f(x) to the right by 2 units. That is, both the x-intercepts and y-intercepts differ between the two functions.

Answer:

D. 0.884

Step-by-step explanation:

I calculated it logically

The value of the amplitude is 0.884, so the correct option is d.

The amplitude is the coefficient that multiplies the sine function.

In this case, the function is:

y = 0.884*sin(0.245*x - 1.093) + 0.400

Comparing this with the general sine equation, you can see that the amplitude is equal to 0.884, so the correct option is d.

Answer:

Step-by-step explanation:

Evaluate the limit n - > ∞ 12n^3 - 2n^2 + 9 / 4n^3

Divide the expression by the highest power of n to have

limit n - > ∞ 12n³/n³ - 2n²/n³ + 9/n³ / 4n³/n³

= limit n -  > ∞12 - 2/n + 9/n³ / 4

Substitute the value of n

= 12 - 2/∞ + 9/∞³ / 4

Since a/∞ = 0

The expression becomes;

= 12 - 0+ 0/4

= 12/4

= 3

Hence the required limit is 3

Answer:

  a. the volume of cube y is 125 times the volume of cube x

Step-by-step explanation:

The volume of cube x is ...

  V = s³ = (1 in)³ = 1 in³

The volume of cube y is ...

  V = (1 in + 4 in)³ = (5 in)³ = 125 in³

The volume of cube y is 125 times the volume of cube x.
