Step-by-step explanation:

Hello there!

Add all of the values in the table to get the total amount of students.

25+25+20+13+5+5+3+2+2=(70)+(23)+(4)=97

Then, make your probability:

P(Drive to school)=(How many students drive)/(All students)

P=40/97

Sean used 1-3/4 cup of sugar to make a dozen brownies. How many cups of sugare are used for 6 dozen brownies?
alisha [4.7K]

Answer:

10 1/2

Step-by-step explanation:

We need to convert 1 3/4 to an improper fraction

1 3/4 = (4*1+3)/4 = 7/4

Multiply this by the number of batches

7/4*6 = 42/4 = 21/2

Change this back to a mixed number

2 goes into 21   10 times with 1 left over

10 1/2

A choir teacher is dividing 3 sopranos and 12 altos into singing groups. he wants each group to have the same combination of sop
Andreyy89
You can have a maximum of 3 groups. This is due to the fact that you only have 3 sopranos to equally divide between groups. Over 3 you would have a group lacking a soprano so 3 is the greatest you can make it.

The circle below has center P, and its radius is 3 m. Given that m 2 QPR=170°, find the length of the minor arc OR.
QveST [7]

Any smooth curve connecting two points is called an arc. The length of the arc m∠QPR is 2.8334π m.

<h3>What is the Length of an Arc?</h3>

Any smooth curve connecting two points is called an arc. The arc length is the measurement of how long an arc is. The length of an arc is given by the formula,

\rm{ Length\ of\ an\ Arc = 2\times \pi \times(radius)\times\dfrac{\theta}{360} = 2\pi r \times \dfrac{\theta}{2\pi}

where

θ is the angle, that which arc creates at the centre of the circle in degree.

Given the radius of the circle is 3m, while the angle made by the arc at the centre of the circle is 170°. Therefore,

The length of an arc = 2πr×(θ/360°) = 2π × 3 ×(170/360°) = 2.8334π m

Hence, the length of the arc m∠QPR is 2.8334π m.
