He table shows how the random number range is assigned to each event. If the following random numbers were assigned, predict the number of Chocolate Chip cookies purchased.

Random numbers: 3, 27, 43, 85, 83

Answers

Answer:

option 2nd is correct that is 2.

Step-by-step explanation:

We have been given the random number range assigned to each event  

And from the given table we can see that the assigned number range of chocolate chip  cookies  is 0-40

So, we will  consider numbers in this range 0-40 from the given random numbers which are 3,27,43,85,83.

So, 3 and 27 will come under the range 0-40

Therefore, only 2 chocolate chip cookies purchased

Therefore, option 2nd is correct that is 2.

True

False

Answers

Answer:

true

Step-by-step explanation:

Answer:

true

Step-by-step explanation:

To represent the situation, you would have to do 14÷3 because there are 3 cats that eat 14 pounds of food in a week and to figure out how much a cat eats in a week, you would have to divide.

The area formed by a plane cutting through a solid perpendicular to its axis is aA.cross section
B.Longitudinal section
C.Cylindrical Section
D.Middle section

Answers

Answer:

cross section

Step-by-step explanation:

The area formed by a plane cutting through a solid perpendicular to its axis is a cross section.

A cross section area is the area obtained from a three dimensional object like sphere when it is sliced at any axis perpendicular at a point. For example cross section of a cylinder sliced parallel to its base is circle.

a population of insects doubles every month. If there are 100 insects to start with, how many will there be in 7 month

Answers

If at the end of every month the population dubbuls then at the end of 7 month there will be 12,800 

month1)200

month2)400

month3) 800

month4) 1600

month5) 3200

month6) 6400

month7)12800

Final answer:

The population of insects is doubling each month. To figure out the population after 7 months, we can use the formula for exponential growth, 2^n, where n is the number of months. Using this formula, after 7 months, there will be 12,800 insects.

Explanation:

The population of insects is doubling each month, so the insect population is growing exponentially. To calculate the population after 7 months, you can use the formula for exponential growth, which is 2^n, where n is equal to the number of time periods, in this case, months.

After 1 month, the population is 100 * 2 = 200. After 2 months, the population is 200 * 2 = 400, and so on. After 7 months, we can calculate as follows:

100 * 2^7 = 100 * 128 = 12800 insects. So, after 7 months, there will be 12,800 insects if the population doubles each month.

plzz help fastt :)

Answers

x=number of corect
y=number of incorrect
5 points for each correct so 5x
-1 point for each incorrect so -y

5x-y=76
solve for x and y

I like putting it into slope intercep tofrm which is y=mx+b
add y to both sides
5x=76+y
subtract 76 from both sides
5x-75=y
y=5x-76

subsitute values for x and get values for y
remember, that julia cannot answer a negative number of incorrect questions so y must be greater than or equal to 0

so solve for minimum
0<5x-76
add 76 to both sides
76<5x
divide by 5
15.2<x
you cannot answer a fraction of a correct quesiton so round up
16 is the minumum number of queswtions correctlyh answered


so
x>16

subsitute 16 for x
y=5(16)-76
y=80-76
y=4

as we subsitute more numbers over 16, we get these points
so (x,y)
