Which of the following is closest to 27.8 × 9.6?. A. 280. B. 300. C. 2,800. D. 3,000
frozen [14]
In order to know which number is closest to 27. 8 x 9.6, we must first get the product between the two numbers. So, 27.8 x 9.6 is equal to 266.88. To round this off, we get 267. Among the given choices, the number that is closest to 267 is only 280. Therefore, the correct answer would be option A.

Solve for x. x3 = 216
vampirchik [111]
I'm assuming the equation is x^3 = 216 or x^3 = 216 (both mean the same thing)

If so, then the solution to x^3 = 216 is x = 6

<span>We can find this by taking the cube root of both sides
</span>x^3 = 216
x = 216^(1/3) .... 1/3 power means cube root
x = 6

Checking the answer:
x^3 = 216
6^3 = 216
6*6*6 = 216
216 = 216
Answer is confirmed

So once again the answer is x = 6. This is assuming the initial assumption made at the top of the problem holds up.

If Will buys 1 kilogram of African rice and 2 kilograms of basmati rice, how much will he spend? brown rice $3.03/kg $3.59/kg st
Alenkasestr [34]

Answer:

Step-by-step explanation:

Sorry, because of lack of punctuation and organization, I cannot determine with any confidence the price per kilo of each of the rices.

He will spend the price of one kg of African rice plus twice the price of Basmati rice.

IF

African rice = $1.69/kg

and

Basmati rice = $3.05/kg

THEN

Cost = 1.69 + 2(3.05) = $7.79

It is estimated % of all adults in United States invest in stocks and that % of U.S. adults have investments in fixed income ins
katovenus [111]

Complete question :

It is estimated 28% of all adults in United States invest in stocks and that 85% of U.S. adults have investments in fixed income instruments (savings accounts, bonds, etc.). It is also estimated that 26% of U.S. adults have investments in both stocks and fixed income instruments. (a) What is the probability that a randomly chosen stock investor also invests in fixed income instruments? Round your answer to decimal places. (b) What is the probability that a randomly chosen U.S. adult invests in stocks, given that s/he invests in fixed income instruments?

Answer:

0.929 ; 0.306

Step-by-step explanation:

Using the information:

P(stock) = P(s) = 28% = 0.28

P(fixed income) = P(f) = 0.85

P(stock and fixed income) = p(SnF) = 26%

a) What is the probability that a randomly chosen stock investor also invests in fixed income instruments? Round your answer to decimal places.

P(F|S) = p(FnS) / p(s)

= 0.26 / 0.28

= 0.9285

= 0.929

(b) What is the probability that a randomly chosen U.S. adult invests in stocks, given that s/he invests in fixed income instruments?

P(s|f) = p(SnF) / p(f)

P(S|F) = 0.26 / 0.85 = 0.3058823

P(S¦F) = 0.306 (to 3 decimal places)
