Yes a Linear Equation can be used and the slope and the y-intercept of the equation are respectively; B: slope = 10, y-intercept = 25

How to Write an equation in Slope Intercept Form?

We are given the coordinates;

(n, p) = (1, 35), (5, 75), (20, 225), (100, 1025)

Now, the way to find the slope is;

m = (y2 - y1)/(x2 - x1)

m = (75 - 35)/(5 - 1)

m = 10

The equation that models this is;

(y - 35)/(x - 1) = 10

y - 35 = 10x - 10

y = 10x + 25

Thus, y-intercept is at x = 0.

y = 10(0) + 25

y = 25

On percent error, if 48% is the actual and the error rate is 20%, what is the estimate?

alex41 [277]

The estimate is 57.6 %

Solution:

Given that, On percent error, 48% is the actual and the error rate is 20%

To find: Estimate

Percent error is the difference between a measured and known value, divided by the known value, multiplied by 100%

The formula for percent error is given as:

$\text { percent error }=\frac{\text {estimated value}-\text {actual value}}{\text {actual value}} \times 100$

Here given that,

percent error = 20 %

Actual = 48 %

Estimate = ?

Let "x" be the estimate

Substituting the values we get,

$20 = \frac{x-48}{48} \times 100\\\\20 \times 48 = (x-48) \times 100\\\\960 = x - 48 \times 100\\\\x - 48 = \frac{960}{100}\\\\x - 48 = 9.6\\\\x = 48 + 9.6\\\\x = 57.6$

Thus the estimate is 57.6 %

Miguel has to take two quizzes tomorrow. He has only enough time to study

Taya2010 [7]

Answer:

Option B is correct.

Miguel should study for the Science quiz as he will do worse in that quiz by guessing.

Step-by-step explanation:

Miguel has to take two quizzes

1) 4 true or false questions on History with a 0.5 chance of acing the quiz

Expected number of correct questions = np

n = number of questions

p = probability of acing the test

Expected number of correct questions = 4 × 0.5 = 2

2) 3 multiple choice questions on Science with a 0.2 chance of acing the quiz.

Expected number of correct questions = 0.2 × 3 = 0.6

It is evident that guessing would yield a worse result in the Science quiz with less than 1 question expected to be correct than history, where he is still expected to get 2 questions correctly by guessing.

Hope this Helps!!!
