<h3>There is only one way to score an 18, because all the questions need to score a three, but with 17, any of the questions can score a 2, but only one, the rest must still score a three. there are six ways because there are six questions. it is only a matter of choosing which one. Similarly with 16, but a little more complicated. the ways to get a 16 are, get a two on two questions, or get a one on one question. the ways to get a one are the same as the ways in getting 17, six ways. the ways to get a two on two is to take the six questions and choose the two that receive a two. that is 6 choose 2, or 15 ways so, a student can get a 16 on the test 15+6=21 ways.</h3>

The baseball coach is 70 inches tall. How tall is the child?
tankabanditka [31]

The child is <u>59.4 inches tall</u>, assuming the length from the coach's shoulder to his head cap is approximately 10 inches.

<h3>What is Heigth?</h3>

Height refers to the vertical distance between the top and bottom of something.

Height measures the length of some objects or persons vertically to determine whether it is high or low, according to some ascertained criteria.

<h3>Data and Calculations:</h3>

Baseball coach's height = 70 inches

Coach's shoulder to head = 10.6 inches

Height of the child standing slightly below the coach's shoulder = 59.4 inches (70 - 10.6)

Thus, the child standing slightly below the coach's shoulder is 59.4 inches tall.

Which graph shows the solution to the system of linear inequalities? x – 4y &lt; 4 y &lt; x + 1 Image for option 1 Image for opt
slava [35]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

x-4y ----> inequality A

solve for y

-4y

4y>x-4

y> (x/4)-1

The solution of the inequality A is the shaded area above the dashed line

The slope of the dashed line is positive

The y-intercept is the point (0,-1)

The x-intercept is the point (4,0)

y< x+1 ----> inequality B

The solution of the inequality B is the shaded area below the dashed line

The slope of the dashed line is positive

The y-intercept is the point (0,1)

The x-intercept is the point (-1,0)

Using a graphing tool

The solution of the system of inequalities in the attached figure
