Answer:

Option C is correct.

Bobby has $300 in the yearbook fund and earns $13.50 for each yearbook sold.

Step-by-step explanation:

Slope intercept form: An equation of line is given by: $y=mx+b$ ......[1] where m is the slope and b is the y-intercept

Given the linear equation: $y = 13.50x+300$

Here, x represents the yearbook sold.

On comparing with the equation [1] we have;

m = $13.50

b =300

therefore, the best scenario best matches the linear relationship is:

Bobby has $300 in the yearbook fund and earns $13.50 for each yearbook sold.

Consider the experiment of rolling two standard (six-sided) dice and taking their sum. Assume that each die lands on each of its

Strike441 [17]

Answer:

Step-by-step explanation:

Given that:

2 standard six sided dice are rolled :

Die 1 = 1, 2, 3, 4, 5, 6

Die 2 = 1, 2, 3, 4, 5, 6

Outcome = ordered pair of Number on the two dice

Event = different sum of the ordered pair of numbers.

The number of outcomes in the experiment = the sample space =) number of Faces)^number of dies

= 6^2

= 36 different outcomes

Can someone help me with this!

Stolb23 [73]

Answer:

2. x = 18

3. x = 7

4. missing angles are 73°

Step-by-step explanation:

The simple rules involved here are ...

the sum of angles of a triangle is 180°
angles forming a linear pair are supplementary (total 180°).

Together, these tell you that the external angle of a triangle has the same measure as the sum of the opposite internal angles. (The third angle is the supplement of the external angle.)

Problem 1

Work shown is correct.

Problem 2

Using the above observation, ...

(5x -11)° + (2x +20°) = (11x -63)°

7x +9 = 11x -63 . . . . . collect terms, divide by °

72 = 4x . . . . . . . . . . . add 63-7x

18 = x

Problem 3

The angles of an equilateral triangle are 60°, so that is the measure of the marked angle.

9x -3 = 60

9x = 63 . . . . . . add 3

x = 7 . . . . . . . . .divide by 9

Problem 4

You don't need to find the value of x to answer this question. The base angle of an isosceles triangle is the complement of half the apex angle. This comes from the fact that the two base angles are equal measure.

(apex angle) + 2(base angle) = 180° . . . . sum of angles in isosceles triangle

(1/2)(apex angle) +(base angle) = 90° . . . divide by 2

base angle = 90° -(1/2)(apex angle) . . . . .solve for base angle

Filling in the given apex angle value, we get ...

base angle = 90° -(1/2)(34°) = 73°

Both missing angles are 73°.

If isme estimated that there are 50 students in the seventh grade class but there are actually 40 what is isme’s percent error?

Temka [501]

The percent error is 25 %

Solution:

Given that it is estimated that there are 50 students in the seventh grade class, but there are actually 40

To find: percent error

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 { approximate value }-\text {exact value}}{\text { exact value }} \times 100$$

Here, exact value = 40 and approximate value or estimated value = 50

Substituting the values in above formula,

$\begin{aligned}&\text { percent error }=\frac{50-40}{40} \times 100\\\\&\text { percent error }=\frac{10}{40} \times 100=\frac{100}{4}=25\end{aligned}$

Thus the percent error is 25 %
