Answer:

Approximately 6 buses

If you are wanting know how many vans they are going to need:

26 + 32 -This helps you know how many total kids there are

= 58

58 / 10 -This solves how many buses you'll need

= 5.8 - Round up, and say you need 6 buses.

What survival rate in the 10th year would make the average of loss over the 10 year period equal to 38.0%

Marat540 [252]

Answer: 63%

Step-by-step explanation:

First step

Find the 10th year rate of loss that will make the average of loss over the 10 years to equal 38.0%.

Assume this rate is x;

$\frac{(36.2 + 29.0 + 46.2 + 37.5 + 40.9 + 40.0 + 32.6 + 40.5 + 40.1 + x)}{10} = 38.0\\\\\frac{343 + x}{10} = 38\\\\x = 380 - 343\\\\x = 37$

x = 37%

Second step - Survival rate

The survival rate is calculated by;

= 1 - rate of loss

= 1 - 37%

= 63%

Write an expression for the sequence of operations described below.1)) multiply 7 by 8, then divide f by the resultDo not simpli

nignag [31]

We need to write an expression for the operations:

$\begin{gathered} \text{ multiply 7 by 8} \\ \\ \text{dived f by the result} \end{gathered}$

The first operation (multiplication) can be represented as:

$7\cdot8$

The second operation (the division of f by the previous result) can be represented as:

$f\div(7\cdot8)$

Notice that we need the parenthesis to indicate that the product is the first operation to be done.

Answer:

$f\div(7\cdot8)$
