Answer:

P(1 and 2) = 1/16

Step-by-step explanation:

There is a 1/4 chance of selecting the correct answer to the 1st question as there is a 1/4 chance of selecting the correct answer to the 2nd question. Since both events are independent, their probabilities are multiplied. Therefore, the probability that Jacqueline will select the correct answer for problems 1 and 2 is (1/4)(1/4)=1/16

Nina's grandmother deposits 3000 into a saving account for her account pays 5.5% simple interest on an annual basis if she does
sashaice [31]

Answer:

$288.8

Step-by-step explanation:

Using I=Prt, we know that the 3000 is the P, 5.5% is the r, and 21 months is the t. The t goes by years, so 21 months=1.75 years. To find the interest, we do 3000*5.5%*1.75 which is 288.75. Then the problem requires you to round to the nearest tenth, so now, the answer is $288.8

The first column has 10 cubes.

The question states that the other two columns each have 4 fewer cubes than the first column.

Column 3: 6 Cubic units

10 + 6 + 6 = 22
