How many radians does the minute hand of a clock rotate through over half an hour? How many degrees?

Answers

Answer 1

Answer:

Answer:

So minute hand will rotate $\pi radian$ in half an hour

Step-by-step explanation:

In one hour minute hand of clock rotate about 360°

So in half an hour minute hand clock rotate $(360)/(2)=180^(\circ)$

We have to find how many minute hand rotate in radian

For conversion of degree to radian we have to multiply with $(\pi )/(180)$

So $180^(\circ)=180* (\pi)/(180 )=\pi radian$

So minute hand will rotate $\pi radian$ in half an hour

in the xy-plane, the graph of the function f is a line. if f(2)=7 and f(12)=1, what is the value of f(7)?

Answers

Given that the function is a line

[f(7) - f(2)] / [7 - 2] = [f(12) - f(2)] / [12 - 2]

[f(7) - 7] / 5 = [1 - 7] / 10

[f(7) - 7] = 5 * [-6] / 10

[f(7) - 7] = - 3

f(7) = - 3 + 7 = 4

Alex and Jackson are brothers who are selling mums for a football fundraiser. Together they have sold 37 mums. If Alex has sold 19 more mums than Jackson, how many mums has Jackson sold? Use X to represent the number of mums alex sold and y to represent the number of mums Jackson sold.

Answers

Jackson has sold 18, that’s the only possibility.

x = mums sold by Alex

y = mums sold by Jackson

$\boxed{\begin{array}{llll} \stackrel{ \textit{together they've sold 37} }{x + y = 37} \n\n\n \stackrel{ \textit{Alex has sold}}{x} = \stackrel{ Jackson }{y} + 19 \end{array}}\hspace{5em} \begin{array}{llll} \stackrel{\textit{substituting on the 1st equation}}{(y+19)~~ + ~~y~~ = ~~37}\n\n 2y+19=37\n\n 2y=18\n\n y=\cfrac{18}{2}\n\n y=9 \end{array}$

What is the study of mathematical probabilities, distributions and deviations?

Answers

Statistics. Statistics is a branch of mathematics which is the scientific study of mathematical values pertaining to qualitative descriptions and transcribe them into quantifying values such as the descriptive statistics and infuses these quantities in the field of inferential statistics. In these two categories involve probabilities, distribution and deviations which are mainly compositions of the descriptive statistics. Inferential statistics will involve comparison and variation of the given values. Methods are t-test, analysis of variance, and two-way analysis of variance and other methods.

Two cylindrical containers are shown. Container A has radius r and height h and holds a maximum of 42 ounces of water. Container B has radius r and height 1.5h. What is the maximum amount of water that Container B can hold?

Answers

Volume of a cylindrical container=πr²h
Container A:
πr²h=42 ounces of water.

Countainer B.
Volume of Container B=πr²(1.5 h)=1.5(πr²h)=1.5(42 ounces of water)=63 ounces of water.

Answer: the maximum amount of water that Container B can hold is 63 ounces of water.
