day. One box of brownies is enough for 16 teachers. How many boxes of brownies will

Samantha need to make in order to have enough for the entire staff at Arlington

Elementary School?

F

G

4 boxes, because 73 - 16 is about 4

4 boxes, because 73 : 16 is about 456

5 boxes, because 73 - 16 is about 4.56

Ether 4 or 5 because 73 - 16 is about 4.56

H

Answer:
It’s 5 boxes because..

4 x 16 = 64 so that wouldn’t be enough

However:

5 x 16 = 80 which is enough for 73 people

Hope this helps! Have a nice day :)

However:

5 x 16 = 80 which is enough for 73 people

From data gathered in the period 2008−2012, the yearly value of U.S. exports can be modeled by the function E(x) = −228x3 + 2,252.8x2 − 6,098.5x + 11,425.8 where x is the number of years after 2008 and E(x) is the value of exports in billions of dollars. The yearly value of U.S. imports can be modeled by the function I(x) = −400.4x3 + 3,954.4x2 − 11,128.8x + 17,749.6 where x is the number of years after 2008 and I(x) is the value of imports in billions of dollars. Estimate the total value the U.S. imported and exported in 2011. Round to the nearest whole number. About billion dollars were imported and exported by the U.S. in 2011.

A flywheel is attached to a crankshaft by 12 bolts, numbered 1 through 12. Each bolt is checked to determine whether it is torqued correctly. Let A be the event that all the bolts are torqued correctly, let B be the event that the #3 bolt is not torqued correctly, let C be the event that exactly one bolt is not torqued correctly, and let D be the event that bolts #5 and #8 are torqued correctly. State whether each of the following pairs of events is mutually exclusive.a. A and Bb. B and Dc. C and Dd. B and C

A normal population has the mean of 10 and the variance of 25 . A random sample of size n-28 is selected. (a) Find the standard deviation of the sample mean. Round your answer to two decimal places (e.g. 98.76) (b) How large must the sample be if you want to halve the standard deviation of the sample mean?

**Answer:**

0 and arctan(0.5)

**Step-by-step explanation:**

if sin2x=2sinx*cosx and 1=sin²x+cos²x, then

cos²x+2sinxcosx-sin²x-cos²x=0;

2sinxcosx-sin²x=0; (to divide by cos²x)

2tanx-tan²x=0;

**Answer:**

(-3,-1)

**Step-by-step explanation:**

You can graph both of the points on desmos, and then look at the slope from p1 to the midpoint. so you can get the slope, and use it to get the p2. the slope is -4/6. So you get that answer.

A. $45.00

B. $25.00

C. $4.50

D. $22.50

**Ivan's** annual earnings for this bond is** $45.00**

A bond is a **pledge**, made by a borrower to pay a **loan **taken back to the **lender** with an interest.

Ivan's annual interest earning would be :

= $1,000 x 4.5 %

= **$45 per year**

Hence, Ivan's** annual earnings** for this bond is **$45.00**

In **U.S. dollars**, the **equivalent money** will be **$100.74**

- A mathematical expression is made up of
**terms (constants and variables)**separated by**mathematical operators.**

- A mathematical equation is used to
**equate two expressions.**

- Equation modelling is the process of writing a
**mathematical verbal expression**in the form of a mathematical expression for**correct analysis, observations**and**results**of the given problem.

- For any
**function y = f(x),**Domain is the set of all possible values of**[y]**that exists for different values of**[x]**.**Range**is the set of all values of**[x]**for which**[y] exists.**

Given is your dinner in London cost **82 British pounds**

Then in **U.S. dollars**, the **equivalent money** will be equivalent to -

x = 82 pounds = 82 x 1.2286 = $100.74

**x = $100.74**

Therefore, in **U.S. dollars**, the **equivalent money** will be $100.74

the answer is $108.32

**Answer:**

- n + q = 25
- 0.05n + 0.25q = 4.05

**Step-by-step explanation:**

*Two equations* are required to represent this problem as posed.

1. An equation for the number of coins:

n + q = 25

2. An equation for the value of the coins:

0.05n + 0.25q = 4.05

6.5 mph and a giraffe travels for 2

hours at ll mph, who covers more

distance?

E. elephant

F. giraffe

G. They travel the same distance.

H. cannot be determined based on the

information provided

Q2

The elephant; 6.5 mph for 4 hours equates to 26 miles, while the Giraffe only covers 22 miles (2*11)

The elephant covers more distance than the giraffe.

To determine who covers more distance, we need to calculate the distance traveled by each animal. The distance traveled can be calculated using the formula: distance = speed × time. For the elephant, the distance is 6.5 mph × 4 hours = 26 miles. For the giraffe, the distance is 11 mph × 2 hours = 22 miles. Since the elephant covers a greater distance, the answer is **E. elephant**.
