Answer:

3 pencils

Step-by-step explanation:

eraser= 0.25

pencil= 0.75

2(0.25)= cost of erasers

0.5 + p=2.75 (p=pencils)

-0.5         -0,5

p=2.25

divide 2.25 by 0.75

=3

Jessica’s Spanish test scores are 98, 74, 88, 83, 91, and 85. Find the range, median, first and third quartiles, and interquarti
seraphim [82]

Answer:

Range = 24; Median = 87.5; Q1 = 83; Q3 = 91; IQR = 8

Step-by-step explanation:

98, 74, 88, 83, 91, 85

(a) Sort the numbers

74, 83, 85, 88, 91, 98

(b) Range

Max. = 98; min. = 74

Range = max. - min. = 98 - 74 = 24

(c) Median

The median (Q2) is the middle number when we arrange the observations in order.

There is an even number of observations, so the median is the average of the third and fourth values.

The average of 85 and 88 is 87.5, so the median is 87.5.

Half of Jessica's grades are above 87.5 and half are below.

(d) First quartile

(74, 83, 85), (88, 91, 98)

The first quartile (Q1) is the median of the numbers below Q2.

The median of 74, 83, and 85 is 83.

First quartile = 83

One fourth of Jessica's grades would be below  83.

(e) Third quartile

The median of 88, 91, and 98 is 91.

Third quartile = 91

One fourth of Jessica's grades would be above 91.

(f) IQR

IQR = Q3 - Q1 = 91 - 83 = 8.

Half of Jessica's grades would be in the range 83 to 91.

Graph f(x)= -(x-2)²+4<img src="https://tex.z-dn.net/?f=" id="TexFormula1" title="" alt="" align="absmiddle" class="latex-formula
Mandarinka [93]

Answer: See the graph attached.

Step-by-step explanation:

The standard form of a quadratic function is:

f(x)=a(x-h)+k

Where (h,k) is the vertex of the parabola.

If a is negative, then the parabola opens down.

Then, for the function:

f(x)=-(x-2)^2+4

You can identify:

h=2\\k=4

Then the  vertex of the parabola is at (2,4)

Note that a=-1, therefore the parabola opens down.

Find the intersection with the x-axis. Substitute f(x)=0 and solve for x:

0=-(x-2)^2+4\\0=x^2-4x\\0=x(x-4)\\\\x_1=0\\x_2=4

Knowing that the vertex is at (2,4), the parabola opens down and it intersects the x-axis at x=0 and x=4, you can graph the function, as you observe in the figure attached.

A coach ordered 1,565 flying discs for field day. The order is shipped in 5 boxes, with the same number of flying discs in each
Kruka [31]

Answer: 313 in each box.

Step-by-step explanation: So you have 1,565 flying discs, and they are DIVIDED into 5 boxes, you would divide 1,565 by 5, with that, you keep on subtracting down to get to where you cannot subtract anymore, which gets you down to your answer!

NOTE: I was in class at this time, so that's why I didn't type as much as I should! Your welcome!
