Answer:

C. 34%

Step-by-step explanation:

I already answered this, but here goes.

Hello there!

Divide the solutions into 100s, and find their percentages.

60/100=0.6*40=24

40/100=0.4*25=24+10

24+10=34 %

Answer:

34%

Step-by-step explanation:

To find the concentration of the new solution, take the percent time the amount of each of the solutions

40 ml* 25% + 60 ml * 40% = 100 ml* percent

40 * .25 + 60 *.40 = 100 * P

10 + 24 = 100 P

34 = 100 P

Divide each side by 100

34/100 = P

.34 = P

Changing to a percent

34% = P

Secants BE and CF intersect at point D inside A. What is the measure of CDE?
Aleks04 [339]
MCE = 360 - (150 + 70 + 50)
mCE = 360 - 270
mCE = 90

<CDE = 1/2(mBE + mCE)
<CDE = 1/2(150 + 90)
<CDE = 1/2(240)
<CDE = 120

answer
<CDE = 120°

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.

Help please, Which expression does not belong? Explain your reasoning.
ZanzabumX [31]

Answer:

My best answer is option number 4.

Step-by-step explanation:

Because the first 3 answers follow a specific pattern in addition and division, i.e. they only go up to 4 different numbers, whereas with the 4th option, that changes. Not only that, but if you look closely, the 4th option adds 6 to itself 5 times, that's the same as 6x5, which equals 30, so if you divide 30 by 5, its almost pointless seeing as how you already know it's gonna get you 6.
