The following are the last 10 run scores Colin got in cricket:

Citrus2011 [14]

Answer:

a) 21

b) 21

Step-by-step explanation:

Given 10 scores: 19, 15, 34, 29, 13, 35, 10, 19, 14, 22

a) Mean

= (sum of scores) / number of scores

= (19+15+ 34+ 29+ 13+ 35+ 10+ 19+ 14+ 22) / 10

= 210 / 10

= 21

b) one more score of 21 is added

hence

number of scores = 10 + 1 = 11

sum of scores = 210 + 21 = 231

Mean = (sum of scores) / number of scores

= 231 / 11

= 21

Find the surface area of the hexagonal prism

arsen [322]

Answer:

$4,636.8 \: {in}^{2}$

Step-by-step explanation:

Surface area of the hexagonal prism

= Area of base * Height

= 6*Area of one triangle *height

$= 6( \frac{1}{2} \times 8 \times 6.9) \times 28 \\ \\ = 6(4 \times 6.9)28 \\ \\ = 6 \times 27.6 \times 28 \\ \\ = 4,636.8 \: {in}^{2}$

Rina8888 [55]

Answer:

Step-by-step explanation:

$x,\ y-the\ numbers\\\\\text{The sum of four times a number and five times another number is -28:}\\\\4x+5y=-28\\\\\text{The sum of nine times the first number and two times the second number is 11:}\\\\9x+2y=11\\\\\text{We have the system of equations:}\\\\\left\{\begin{array}{ccc}4x+5y=-28&\text{multiply both sides by2}\\9x+2y=11&\text{multiply both sides by (-5)}\end{array}\right\\\\\underline{+\left\{\begin{array}{ccc}8x+10y=-56\\-45x-10y=-55\end{array}\right}\qquad\text{add both sides of the equation}$

$.\qquad-37x=-111\qquad\text{divide both sides by (-37)}\\.\qquad\qquad\boxed{x=3}\\\\\text{Put the value of x to the first equation:}\\\\4(3)+5y=-28\\12+5y=-28\qquad\text{subtrac 12 from both sides}\\5y=-40\qquad\text{divide both sides by 5}\\\boxed{y=-8}$

Question 9 of 26

Arturiano [62]

Answer: f(x) = 1.2(x/2) if 120 ≤ x ≤ 240

Step-by-step explanation:

Let, she made f(x) sundaes in x minutes.

Then according to the question,

She just makes sundaes for a single shift of at most 4 hours and at least 2 hours,

⇒ She can make sundaes for a single shift of at most 240 minutes and at least 120 minutes,

That is, 120 ≤ x ≤ 240

Now, She can prepare 1 sundae every 2 minutes,

⇒ She can prepare 1/2 sundae every 1 minutes,

⇒ She can prepare x/2 sundae every x minutes,

Also, she earns $1.20 for each sundae she makes.

Thus, her total earning in x minutes,

$f(x)= 1.2\times \frac{x}{2}$

⇒ $f(x)= 1.2(\frac{x}{2})$

Where, 120 ≤ x ≤ 240

Which is the required function related her earnings to the number of minutes she works.
