Answer:

<em>The average yearly change in the value of the card is $15 every year.</em>

Step-by-step explanation:

<u>Average Change</u>

The change in the value of the baseball card bought by Connor was $120 in 8 years.

The average yearly change in value is calculated as:

Avg Change=$120 / 8 years = 15 $/yr

The average yearly change in the value of the card is $15 every year.

algol [13]

Using linear function concepts, it is found that the correct statements are given by:

  • The number of biology degrees increases by about 2,414 each year after 2000.
  • About 73,000 students graduated with degrees in psychology in 2000.
  • In 2000, more students graduated with psychology degrees than biology degrees.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value.

In this problem, the number of college seniors who graduated with a bachelor's degree in psychology, in t years after 2000, is modeled by:

P(t) = 2,376t + 73,219.

For biology, the amount is given by:

B(t) = 2,414t + 56,545.

Then, the true statements are given by:

  • The number of biology degrees increases by about 2,414 each year after 2000.
  • About 73,000 students graduated with degrees in psychology in 2000.
  • In 2000, more students graduated with psychology degrees than biology degrees.

On a clear day you can see about 25.2 miles from the upper observation platform of the Eiffel tower in Paris. Using the formula
fredd [130]

Answer:

D. 914 feet

Step-by-step explanation:

We are given the distance that a person can see on a clear day from the upper observation platform of the Eiffel tower in Paris. We are then required to estimate the height of the upper observation platform using the formula;

d=\frac{5}{6}\sqrt{h}

Where d is the distance and h the height of the upper observation platform. The first step would be to solve for h, that is make h the subject of the formula in the above equation;

We multiply both sides of the equation by the reciprocal of 5/6 which is 6/5;

\sqrt{h}=\frac{6}{5}d

The next step is to eliminate the square root on the Left Hand Side of the equation by squaring both sides;

h=1.44d^{2}

Given d is 25.2, h becomes;

h=1.44*25.2^{2}\\h=914.4576

To the nearest whole number, h becomes 914

Help help<br><br> Order these fractions from least to greatest.
Dmitrij [34]

Answer:

\frac{5}{9}, \frac{7}{9}, \frac{8}{9}

Step-by-step explanation:

The answer is: \frac{5}{9}, \frac{7}{9}, \frac{8}{9}

And this question isn't to difficult, and the trick is realizing they all have the same denominator.

The denominator is essentially saying how many pieces of the whole (1) is being broken into.

So the denominator 9, means that you're breaking up the number 1 into 9 pieces.

The numerator is telling us how many pieces of this "broken up 1" the number has.

So 8/9 has more of these "broken up pieces" than 7/9, and it's so vitally important that these numbers have the same denominator.

For example: 1/2 and 30/90

30/90 may appear to be bigger, since the numerator of 30, but it's actually smaller.

The reason for this is because we can simplify it to: 1/3 by dividing both sides by 30 so the value remains the same.

Now we can actually compare 1/2 and 1/3 without changing the denominators.

1/3 is "one piece" of a broken up one, that was "broken" into 3 pieces.

1/2 is "one piece" of a broken up one, that was "broken" into 2 pieces.

So if I split one whole, into three pieces, each individual piece is going to be smaller than had I split that one whole into 2 pieces.

So 1/2 is actually bigger than 1/3
