Answer:

To run one lap Lin takes 1.6 minutes.

Step-by-step explanation:

To find this answer you would do 8 divided by 5. Always remember when dividing time goes first unless the instructions / directions / your teacher says differently. So, when you do 8 divided by 5 the answer you get is 1.6, and there is your answer. Also to check your answer you can do 1.6 times 5, and you get 8, so you know that 1.6 is the correct answer.

A manager records the number of hours, X, each employee works on his or her shift and develops the probability distribution belo

Reika [66]

Answer:

c. 2

Step-by-step explanation:

Given : X = No. of hours worked

No. of people work for the manager = 50

X = 3, 4 , 5 , 6 , 7, 8

P(X) = 0.1 , ? , 0.14 , 0.3 , 0.36 , 0.06

To Find : No. of people work for four hours

Solution : First understand the fact that sum of all probabilities is equal to 1

So, sum of all values of P(X) = 1

⇒ $0.1+?+0.14+0.3+0.36+0.06 = 1$

⇒ $0.96+? = 1$

⇒ $?= 1-0.96$

⇒ $? = 0.04$

So, the probability of no. of people worked for 4 hours is 0.04.

⇒P(4)=0.04

Thus , To calculate no. of people work for four hours :

$0.04\times 50$

⇒ 2 no. of people work for four hours per shift .

WILL MARK BRAINLIEST CAR!!!! HELP

Digiron [165]

Answer:

111°

Step-by-step explanation:

Let the centre of the circle be C

mRQ=157 (marked)

The angle at the centre of a circle standing on an arc is twice any angle at the circumference, standing on the same arc. So <SCR=2(SQR)=2(46)=92. mSR=<SCR=92

All the arc measure add up to 360 so:

mSQ+mRQ+mSR=360

mSQ+157+92=360

mSQ=360-249=111

#31. I just need to know how you did it! THANK YOU

kirill [66]

Answer:

m=60º

n=30º

Step-by-step explanation:

a triangle is 180º total

an equilateral triangle has all 60º angles

since the one symbol for a right angle is cut between two triangles you can say that the one angle in the equilateral triangle +n=90º

substituting the values 60+n=90

so n=30

Then since a triangle is 180º you can make an equation that says 180=90+m+n

again substituting 180=90+m+30

60=m

an easy way to check is 180=90+30+60 180=180

What is the average of 66, 62, and 82

Usimov [2.4K]

Add the three numbers together, then divide by 3 because there are 3 numbers.

66+62+82= 210 = 70

70 is the average of these 3 numbers.

Hope this helps! :)
