String A is 18 inches long but 15 shorter than B. this means to get be you need to add string A(18) to 15. that would be 33 inches. string C is half the length of A(18) so you divide 18 by 2(half) to get string C. that would 9 inches

10a. The y-intercept of the estimated line of best fit is at (0,b). Enter the approximate value of b. Round your estimate to the

vredina [299]

Answer:

The answer is below

Step-by-step explanation:

The equation of a straight line is given as:

y = mx + b; where m is the slope of the line and b is the y intercept (that is value of y at x = 0).

a) From the graph, we can see that the straight line touches the y axis at $100 in which the temperature is 0 degrees. Therefore the y intercept is:

(0, 100)

b) The slope of the line can be gotten by taking two points that the line passes through. Using the points (0, 100) and (12, 500):

$slope(m)=\frac{y_2-y_1}{x_2-x_1} =\frac{500-100}{12-0} =33.3$

Find the distance between the following coordinates: I(-a,b), J(a,b)

olchik [2.2K]

Answer:

Step-by-step explanation:

using distance formula:

√(x₂-x₁)² + (y₂-y₁)²

putting values,

√{a-(a)}² + {b-b}² = √ {a+a}² + 0²

= √(2a)² = √4a² = 2a

Hope this helps:)

What is the grade if there are 85 questions and u miss 9

Irina18 [472]

If you miss 9 questions, the how many did you get right?

85 - 9 = 76

So now you got 76 out of 85 correct or 76/85...

Now if you just do the fractional division that is described by the fraction you will get the answer. The fraction bar literally means "divided by", so the fraction means...

76 divided by 85 which equals...

.8941

Now to convert to percentage we multiply by 100 (move the decimal 2 places to the right)

.8941 x 100 = 89.41% Round to nearest one percent...

89%
