Answer:

x = 10, y = 0

Step-by-step explanation:

x + 2y = 10

x = 10 - 2y (Bring the 2y to the right)

16y = -3x + 30

16y = -3(10 - 2y) + 30 (Substitute x to 10 - 2y)

16y = -30 + 6y + 30 (Expand brackets)

10y = 0 (Bring y to the left)

y = 0

x = 10 - 2(0) (Substitute y = 0)

x = 10

x = 10, y = 0

A teacher is buying pencils for her classroom. If a dozen pencils cost $0.97, how many pencils can she purchase with $5?

mixas84 [53]

Answer:

The teacher can purchase 61 pencils with $5

Step-by-step explanation:

This is a simple proportion problem. It can be solved by pure logic reasoning without any formulas

It a dozen pencils cost $0.97, each pencil cost $0.97/12=0.08083

With $5 she will be able to purchase 5/0.08083=61.85 pencils

We must round to the nearest lower integer

The teacher can purchase 61 pencils with $5

The football team has 2 large water containers. Each container holds 345π in3 of water. Each player is given a cylindrical water

raketka [301]

Answer:

They'll be able to get 34 bottles from the containers.

Step-by-step explanation:

Since the bottles are cylindrical we can calculate their volume by using the following formula:

V = base_area*h

V = \pi*(r^2)*h

r = d/2 = 4/2 = 2 inches

V = 3.14*(2^2)*5 = 3.14*4*5

V = 3.14*20 = 62.8 inches^3

In order to know how many full bottles the players will get we need to divide the total volume of the containers, which is given by the sum of the volume of each container, and divide it by the volume of each bottle. We have:

bottles = (345*pi + 345*pi)/62.8 = 690*pi/62.8 = 2,166.6/62.8 = 34.5

Since the problem wants the amount of full bottles we only take the integer part, so they will be able to get 34 bottles from the containers.

Could someone PLEASE just HELP me with this question.

agasfer [191]

Answer

$\frac{7}{37}$

Detailed Explanation

To simply answer this, since .189 has three digits we are going to be inserting 999 as the denominator since it is a repeating decimal.

$\frac{189}{999}$

We could simplify the answer!

$\frac{189}{999}$

Therefore, the answer would simply be $\frac{7}{37}$

$\frac{7}{37}$

Always Remember

In the future, always remember whenever you have a three digit decimal and the problem asks you to convert it into a fraction, you should always insert 1000 as the denominator (the numerator is basically the decimal without the decimal point) and simplify if necessary.

Mary is the manager of a new clothing shop. The shop located in a new shopping mall and Mary wants to estimate the average daily

sergeinik [125]

Explanation:

a) First, note that the Type I error refers to a situation where the null hypothesis is rejected when it is actually true. Hence, her null hypothesis would be H0: mean daily demand of her clothes in this region should be greater than or equal to 100.

The implication of Type I error in this case is that Mary rejects that the mean daily demand of her clothes in this region is greater than or equal to 100 when it is actually true.

b) While, the Type II error, in this case, is a situation where Mary accepts the null hypothesis when it is actually false. That is, Mary accepts that the mean daily demand of her clothes in this region is greater than or equal to 100 when it is actually false.

c) The Type I error would be important to Mary because it shows that she'll be having a greater demand (which = more sales) for her products despite erroneously thinking otherwise.
