Answer:

Option B.

Step-by-step explanation:

It is given that Lisa needs 250 yards of yarn to knit a hat.  

She has 185 yards of yarn and needs to buy the rest.

Let y to be the number of yards of yarn she needs to buy.

Number of yards of yarn she needs to buy + Number of yards of yarn she has = 250

y+185=250

Subtract 185 from both sides.

y+185-185=250-185

y=65

The required equation is y+185=250 and solution is y=65.

Therefore, the correct option is B.

Which sample is representative of the population being studied?
Lesechka [4]
First, let's break down what the difference between a sample and population is. A sample is a small part or quantity intended to show what the whole is like. A population is all inhabitants of a town, country, or the world. Samples are only representative of the population if the data collected is being collected in a fair manner. In answer choices A - C, the researcher is collecting data in locations specific to what is being studied. The outcome is likely to be bias because of the method in which the data is being collected. It is for that reason that the correct answer is D.

His investment doubles so it comes to  3000 * 2 = $6000.

Substituting in the formula>

6000 = 3000e^7.2r   ehere r  is the interest rate.

e^7.2r = 2

Taking logs

7.2r = ln 2

r = ln2 / 7.2

r = 0.096

So the rate is 9.6%.
