I'm not sure if this is simply a true/false question but if so the answer is true. With a standard deviation of 1.8, your tests would always remain in the A range.

Hope that helps.

An ice cream factory makes 280 quarts of ice cream in 2 hours. How many

Akimi4 [234]

Answer:

6720 quarts could be made in 48 hours.

The rate per day is 3360

Step-by-step explanation:

280/2 = 140 per hour.

In 24 hours ( a whole day) 24 x 140 = 3,360

In 48 hours (2 days) 3,360 x 2 = 6720 or 48 x 140= 6720

6. Write the explicit formula for the geometric sequence of the height of the ball on the 10th bounce.First bounce: 54 inchescom

Nat2105 [25]

The height of the ball initially is 54 inches. The common ratio has been provided which is 0.750.

The explicit formular for the geometric sequence is shown as;

$\begin{gathered} ar^{n-1} \\ \text{Where a is the first term in the sequence,} \\ r\text{ is the common ratio betw}een\text{ every successive term} \\ \text{And n is the nth term} \\ \text{The explicit formular for the height of the ball on the 10th bounce is;} \\ ar^{n-1} \\ 54\times(0.750)^{10-1} \\ 54\times(0.750)^9 \\ 54\times0.07508468\ldots \\ 4.0545 \end{gathered}$

The explicit formula is shown as;

54 x (0.750)^9

The rest is simply to solve for the height on the 10th bounce
