the equation ^y= 2.391x+57.420 models The taste rating of a serial y in a survey where x is the number of grams of sugar per serving

what does the y intercept of the equation represent in context of the situation

a cereal with 0 grams of sugar has a rating of about 2.391

the average number of grams of sugar is 2

the average number of grams of sugar is 57

a cereal with 0 grams of sugar has a rating of about 57

(D)a cereal with 0 grams of sugar has a rating of about 57

Step-by-step explanation:

The equation y= 2.391x+57.420 models the taste rating of a cereal y in a survey where x is the number of grams of sugar per serving.

When x=0

y= 2.391(0)+57.420

y=57.420

Since x is the number of grams of sugar per serving, and x=0 at the y-intercept.

We therefore state that in this context, a cereal with 0 grams of sugar per serving has a rating, y of about 57.

The correct option is D.

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.  

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
