Answer:

The rate  of descent is -67.5\frac{feet}{minute}

Step-by-step explanation:

we know that

The formula to calculate the rate or slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

Let

x------> the time in minutes

y----> the elevation in feet

we have

A(0,6,678)\ B(48,3,438)

Substitute the values

m=\frac{3,438-6,678}{48-0}

m=\frac{-3,240}{48}

m=-67.5\frac{feet}{minute}

What does the model predict for 1900?
vagabundo [1.1K]

Answer:

64.0% is the correct answer.

Step-by-step explanation:

As per the given scatter plot of voter turnout every year:

X axis represents the year and

Y axis represents the percentage of people who voted.

The model was predicted as per the equation:

y = -0.1271x + 307.53

<u>To find:</u> Prediction for the year 1900.

Putting the value of x=1900, the value of y will be the predicted value of the model i.e. the value of percentage of voter turnout.

\Rightarrow  y = -0.1271\times (1900) + 307.53\\\Rightarrow  y = -241.49 + 307.53\\\Rightarrow  y = -64.04\%\\OR\\y \approx 64.0\%

So, the model predicts y \approx 64.0\% for the year 1900.

X + 2x + 7 = 3x - 7<br> How do you solve this?
Stella [2.4K]

Answer and explanation:

<em>To solve this, you must find what x equals</em>

x + 2x + 7 = 3x - 7 <em>Add together any numbers that can be added on their side</em>

3x + 7 = 3x - 7  <em>Then subtract 7 from both sides to get 3x alone</em>

3x = 3x - 14 <em> Then subtract 3x from both sides to get x</em>

<h3><em>*The x's cancel each other out so you must have typed the equation wrong. Please check to see any mistakes you may have made*</em></h3>

Write the answer in scientific notation and in standard form.Round to the appropriate number of significant digits.
Aleks [24]

Hey there, the answer is C.

After multiplying, you will get .37278. However, it's asking you to consider the significant figure of 3 so you'll have to round it to .373. C has that only option
