Answer: 7bb +19 ll ≥210

Step-by-step explanation:

Hi, to answer this question we have to write an inequality:

The product of the number of hours he works babysitting (bb) and the amount he earns per hour (7); plus The product of the number of hours he works lifeguarding (ll) and the amount he earns per hour 19; must be higher or equal to the amount he must earn this week (210)

Mathematically speaking:

7 bb + 19 ll ≥210

olga2289 [7]

Answer:

The minor arc HK is 60 degrees

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The inscribed angle is half that of the arc it comprises.

so

m\angle HLK=\frac{1}{2}(arc\ HK)

we have

m\angle HLK=30^o

substitute the given value

30^o=\frac{1}{2}(arc\ HK)

arc\ HK=60^o

Remember that the measure of the minor arc must be less than 180 degrees

therefore

The minor arc HK is 60 degrees

Determine whether the underlined number describes a population parameter or a sample statistic. Explain your reasoning. Sixty-fi
Levart [38]

Answer: A. The number is a sample statistic because it is a numerical description of all of the passengers that survived.

Step-by-step explanation:

A population is simply similar items or events that a researcher or an experimenter is interested and wants to carry out an experiment on.

A statistic is simply referred to as the piece of information gotten from the population while a sample statistic is the piece of statistical information which a researcher will be able to get from the statistic.

In this scenario, the number is a sample statistic because it is a numerical description of all of the passengers that survived.

2/(x^2)=4/x+1<br>can any one solve this for me please
levacccp [35]
2/X^2=4/X+1                                   times by both denominators
2(x+1)=4(x^2)
2x+2=4x^2
4x^2-2x-2=0
(2x+1)(2x-2)=0
x=2x+1 or 2x-2
x=-1/2 or 1
