Answers

the total sale was neither a profit nor loss , 0%

2. How can Diego package all the 64 cookies so that each bag has the same number of them? How many bags can he make, and how many cookies will be in each bag? Find all the possible ways to package the cookies.
:
Divide 64 by multiple numbers, and if they divide evenly that’s how many will be in each bag for the number of bags (number you divided by). For example, dividing 64 by 8 (bags) would be 8 cookies in each bag. You can do this with multiple numbers as long as it goes in evenly

Orchid wants to retile her bathroom floor, which has an area of 40 square feet. She is deciding between two types of custom tiles. The square tile is One-half foot by One-half foot and costs $0.45 per tile. The rectangular tile is 2 feet by One-fourth foot and costs $0.80 per tile.

Answers

Answer:

b. She should choose the rectangular tiles because the total cost will be $8 less.

Step-by-step explanation:

Which tile should Orchid choose to minimize costs? Explain.

a. She should choose the square tiles because the total cost will be $8 less.

b. She should choose the rectangular tiles because the total cost will be $8 less.

c. She should choose the square tiles because the total cost will be $14 less.

d. She should choose the rectangular tiles because the total cost will be $14 less.

Area of a square tile = 1/2 × 1/2

= 1/4

= 0.25 square feet

Area of rectangular tile = 2 × 1/4

= 2/4

= 0.5 square feet

Number of square tile needed = Area of the bathroom floor / Area of the square tile

= 40 square feet / 0.25 square feet

= 160

Number of square tile needed = 160

Cost of square tile needed = number of tiles × cost per tile

= 160 × $0.45

= $72

Cost of square tile needed = $72

Number of rectangular tile needed = Area of the bathroom floor / Area of the rectangular tile

= 40 square feet / 0.5 square feet

= 80

Number of rectangular tile needed = 80

Cost of rectangular tile needed = number of tiles × cost per tile

= 80 × $0.80

= $64

Cost of rectangular tile needed = $64

Cost of square tile needed = $72

Cost of rectangular tile needed = $64

If represents the number of bacteria in a culture at time t, how many will there be at time

Answers

Answer:

Population of bacteria at  time [tex]t = 6[/tex] is [tex]2441[/tex]

Step-by-step explanation:

The complete question is

If [tex]y = 10 (2.5)^t[/tex]represents the number of bacteria in a culture at time t, how many will there be at time [tex]t = 6[/tex]

Solution

Given

The population of bacteria after time t is equal to [tex]y = 10 (2.5)^t[/tex]

Population when at time [tex]t = 6[/tex]

We will substitute the value of time in above equation.

[tex]y = 10 (2.5)^6\\y = 10 *244.14\\y = 2441.4 = 2441[/tex]

Solve the simultaneous equations by substitution
5x+6y=−11
5x=2y−3

Answers

Answer:

y= -1, x= -1

5x+6y=-11

-(5x-2y=-3)

     8y=-8

      y=-8/8

      y= -1

5x+6(-1)=-11

5x-6     = -11

        5x=-11+6

        5x=-5

          x=-5/5

          x=-1

The required solution of the simultaneous equation is x = -1 and y = -1.

Given that,
To solve the given simultaneous equation,
5x+6y= −11
5x = 2y −3

What are simultaneous linear equations?

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

here,
5x = 2y −3 - - - - - (1)
5x+6y= −11
By substitution, from equation 1
2y - 3 + 6y = -11
8y = -8
y = -1
Now,
5x = -2 - 3
x = -1

Thus, The required solution of the simultaneous equation is x = -1 and y = -1.

D

A random sample of 100 taken from a population that is uniform

Answers

Answer:

C

Step-by-step explanation:

Using the Central Limit Theorem, it is found that the option in which is it not appropriate to assume that the sampling distribution of the sample mean is approximately normal is:

C) A random sample of 10 taken from a population distribution that is skewed to the right

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

In option C, there is an skewed variable and a sample size less than 30, hence, the Central Limit Theorem is not applicable.
