Angelo's mother put $50 on his lunch card. He spends the same amount
amid [387]

Answer:

Given that Angelo spends the same amount every day from the amount in

the lunch card, the function of the amount remaining is a linear function.

The constant rate of change of the function is; -5.25

The two ordered pairs used to find the constant rate of change are; (1, 44.75) and (2, 39.5)

Reasons:

The amount Angelo's mother put on the lunch card = $50

A possible table of values to the question is presented as follows;

Required:

The constant rate of the function that gives the amount remaining from the

amount Angelo's mother put on his lunch card.

Solution:

The two ordered pairs that can be used to find the slope or constant rate of change are;

(x₁, y₁) = (1, 44.75), and (x₂, y₂) = (2, 39.5)

With the above two ordered pairs, we have the constant rate of change of the function given as follows;

The constant rate of change for the function that gives the amount remaining in the lunch card is; -5.25

Answer:

The first and third quartiles were calculated incorrectly. Also, this means the inter quartile range is incorrect.

Step-by-step explanation:

The first quartile is going to be the median of the lower half of the data set {89, 93, 99, 110}  this median is (93+99)/2, or 96.

The third quartile can be calculated the same way with the data set {135, 144, 152, 159} This gives us 148 as the third quartile.

Lastly, the interquartile range is just the difference between the first and third quartiles, which is 52.

15) factor out cos: cos(x)(sin(x)+1)=0
Now this is true when either cos(x)=0 (x=pi/2 and 3pi/2)
Or when sin(x)=-1 (x=3pi/2)
So it's solutions are pi/2 and 3pi/2

Let's use the quadratic formula
\frac{ - b( +  - ) \sqrt{ {b}^{2}  - 4ac} }{4a}
a = 1, b = 0, c = -18
\frac{ - (0)( +  - ) \sqrt{ {(0)}^{2}  - 4(1)( - 18)} }  {4(1)}  \\  \frac{( +  - ) \sqrt{72} }{4}
This is now split into two equations:
\frac{ +  \sqrt{72} }{4}
and
\frac{ -  \sqrt{72} }{4}
Since\frac{ \sqrt{72} }{4}  \\ =  \frac{6 \sqrt{2} }{4}  \\  =  \frac{3 \sqrt{2} }{2}
The answer is
\frac{3 \sqrt{2} }{2}  \: and \:  \frac{ - 3 \sqrt{2} }{2}
which means there are 2 real number solutions to the problem: answer B.
