A vendor sells gloves and scarves. Gloves cost S10 and scarves cost $8. If the vendor sold 20 total items for $176, how many sca
Murljashka [212]

Answer: The vendor sold 9.5 scarves.

Step-by-step explanation:

I know that 10 x 10 is 100. HOWEVER, this only tells how many gloves were sold. To get how many scarves were sold: you need to:

100 + 8x = 176 or 10 x 10 + 8x = 176

176 - 100 = 76 or 10 x 10 = 100   176 - 100 = 76

both problems 76 divided by 8 = 9.5

Thus, my answer would be 9.5 scarves were sold (or if you round, about 10 scarves were sold).

Answer:

The approximated value of JK is 10.6 cm answer (A)

Step-by-step explanation:

∵ JI // KH // LG

∵ XI and XJ are two transversal

∴ \frac{LK}{GH}=\frac{KJ}{HI}

∵ LK = 18 cm , GH = 22 cm and HI = 13 cm

∴ \frac{18}{22}=\frac{KJ}{13}

∴ KJ = (13)(18) ÷ 22 = 10.6363 cm

∴ The approximated value of JK is 10.6 cm

10) A survey of business students who had taken the Graduate Management Admission Test (GMAT) indicated that students who have s
kupik [55]

Answer:

0.79 ; 0.753

Step-by-step explanation:

Given that:

Students who have spent at least five hours studying GMAT review guides have a probability of 0.85 of scoring above 400 :

≥ 5 hours review = 0.85

Students who do not spend at least five hours reviewing have a probability of 0.65 of scoring above 400

< 5 hours = 0.65

70% (0.7) of business students spend atleast 5 hours review time

A.) probability of scoring above 400

(Proportion who spend atleast 5 hours review time * 0.85) + (Proportion who do not spend atleast 5 hours * 0.65)

Proportion who do not spend atleast 5 hours = (1 - proportion who spend atleast 5 hours) = 1 - 0.7 = 0.3

Hence,

P(scoring above 400) = (0.7 * 0.85) + (0.3 * 0.65) = 0.595 + 0.195

= 0.79

B.) probability that given a student scored above 400, he/she spent at least five hours reviewing for the test.

P(spent ≥5 hours review | score above 400) :

P(spent ≥5 hours review) / P(score > 400)

(0.7 * 0.85) / 0.79

0.595 / 0.79

= 0.753

Andrew deposits $300 into an account that earns 2% interest each year. After the first year, Andrew has $306 in the account. Aft
Sliva [168]

Answer:

It is a simple interest account

Step-by-step explanation:

As we might see from the given earnings, the amount of money he earned each year is the same as in the previous year. This means that the amount of money is growing linearly instead of exponentialy. This is characteristic to a simple interest account, which is found by using the formula:

I=Prt

where I = interest earned.

P = principal

r = Interest rate

t = time in years,

if we use this formula to calculate the amount of money earned after t years, we can see it will be the same as the values reported:

I=$300(0.02/year)(1year)=$6

I=$300(0.02/year)(2years)=$12

I=$300(0.02/year)(3years)=$18

So this simple interest account.
