I would say this is considered small sample, because there is nothing really wrong with his survey in terms of quality. it's not like he only survey boys or girls, or like only survey rich or poor people. In other words, his survey is from a random pool, assuming the kids in his grade are mostly normal people. Therefore, I would say that if this person surveyed more people, then he'll get much better data.

Answer:

The answer is Bad sample.

Step-by-step explanation:

The student polls every student in his grade level. It is found that 30 percent on the students polled bring a sack lunch.

The student concludes that 30 percent of the students in the school bring a sack lunch.

Firstly, students of a single grade do not represent the entire school population. The student here asked every student of his class, so the sample was not random. It was biased and bad.

The collected data is not representative of the population, so it is a bad sample or bad sampling.

If a musician uses his credit card to pay for a new violin that costs $2,900 and does not pay on it until the second month, what

OLEGan [10]

Answer:

$97.15.

Step-by-step explanation:

We have been given that a musician uses his credit card to pay for a new violin that costs $2,900 and does not pay on it until the second month. The interest rate of credit card is 3.35% monthly.

We will use interest formula to solve our given problem.

$I=PrT$ , where,

$I=\text{Interest}$ ,

$P=\text{Principal amount}$ ,

$r=\text{Interest rate in decimal form}$ ,

$T=\text{Time}$

Let us convert our given interest rate in decimal form.

$3.35\%=\frac{3.35}{100}=0.0335$

Upon substituting our given values in interest formula we will get,

$I=2,900*0.0335*1$

$I=2,900*0.0335$

$I=97.15$

Therefore, the monthly interest charge at the end of the 1st month will be $97.15.

Step-by-step explanation:

A measurable goal is one measured in a manner that tangible evidence can be presented to show how it was achieved.For example, You can prepare for a Math test on Friday by studying Math every evening and then meeting with your Tutor on Wednesday.

In option C, there is an amount $50 transferred every month in a saving account.

Amount can be presented for checking, there is an element of time/duration for tracking and the destination

The function below is defined for all x except one value of x. If possible, define f(x) at the exceptional point in a way contin

Nataliya [291]

Answer:

F(x=11)= (-31)

Step-by-step explanation:

for the function

F(x) = x² - 13*x + 22/x-11 , for x ≠ 11

then in order to define F(x=11) so F is continuous (see Note below) . By definition of continuity of a function:

F(x) is continuous in x=11 if lim F(x)=F(a) when x→a

then

when x→a , lim x² - 13x + 22/x-11 = lim 11² - 13*11 + 22/11 -11 = -3*11 + 2 = -31 = F(x=11)

then

F(x=11)= (-31)

Note:

F is not continuous in all x since

when x→0⁺ , lim (0⁺) ² - 13*0⁺ + 22/0⁺ -11 = (+∞)

when x→0⁻, lim (0⁻) ² - 13*0⁻ + 22/0⁻ -11 = (-∞)

then

limit F(x) , when x→0 does not exist since the limit from the left and from the right do not converge → since the limit does not exist , the function is not continuous in x=0

How much water should be mixed with 237 ml of ammonia, whose strength is 100%, in order to create a mixture that is diluted to

Vedmedyk [2.9K]

Let the x ml of water be mixed with 237 ml of ammonia whose strength is 100%, in order to create a mixture of 75% strength.
The equation required to solve this will be:
237/(237+x)=75/100
solving for x we get:
237/(237+x)=3/4
237×4=3(237+x)
948=711+3x
3x+711=948
3x=948-711
3x=237
x=237/3
x=79 ml
therefore the amount of water to be added will be 79 ml
