There are 4,800,000 cell phones sold each day in the world. In a sample of 1,000 cell phones, 750 are smart phones. How many smart phones should be part of the entire population of cell phones sold each day?
1,000
3,600,000
750
4,800,000

Answers

Answer: I think the answer is 3600000000, the answer is number 2 which is 3,600,000

Step-by-step explanation: the question says how many smart phones are sold.

In a set of 1,000 integers from 1 to 1,000, an integer chosen at random on a single trial should be an integer from 1 to 25 about 25 out of every 1,000 trials, or one out of every 40 integers selected. A sample of 5 integers selected is shown. Does this sample represent the general rule for picking an integer from 1 to 25 in the population of integers from 1 to 1,000?

A.Yes - the sample is representative of the expected number of integers from 1 to 25 in a sample of 5 integers, which would be none or zero.
B. No - the sample is not representative of the expected number of integers from 1 to 25 in a sample of 5 integers, which would be at least 10.

Reminder: Please do not just say the answer, make sure to include your work on how you got the answer!

A number cube is rolled. What is the probability that a number greater than 4 will be rolled?

1/6
2/3
1/3
5/6

Answers

Answer:

1/3

Step-by-step explanation:

1/3!

six numbers on a die, only 5 and 6 are greater than 4 so that’s two numbers out of the six total that are greater than 4. 2/6 simplifies to 1/3!

1. Select all the equations that have no solution.
a. +6=5+
b. -2(−3)=-2+6
c. 4−4=3+2
d. 4(+1)=3(+2)
e. 5−3=-3+4

Answers

Answer:

a, and e.

Step-by-step explanation:

x+6=5+x has no solution. When you subtract 6 from both sides, you get x=-1+x. We know that x doesn't equal -1+x, so this equation has no solution.

-2(x-3)=-2x+6 has a solution. When you distribute, you get -2x+6=-2x+6.

4-4x=3x+2 has a solution. Subtract 4 from both sides to get -4x=3x-2. Subtract 3x from both sides to get -7x=-2, then divide -2 by -7 to get x=0.285714285714. This equation has a solution.

4(x+1)=3(x+2) has a solution. Distribute to get 4x+4=3x+6. Subtract 4 from both sides to get 4x=3x+2. Subtract 3x from both sides to get x=2. This equation has a solution.

5-3x=-3x+4 has no solution. Subtract 5 from both sides to get -3x=-3x-1. We know that -3x does not equal -3x-1, so we can determine that this equation has no solution.

Answer:

a  and e has no solution

Step-by-step explanation:

A) x + 6 = x +5

Subtract x from both sides

   x + 6 - x = x + 5 - x

        6 = 5 which is not true.

So, this equation has no solution

d) 5 - 3x = -3x + 4

Add 3x to both sides

5- 3x + 3x = -3x + 4 + 3x

5 = 4         which is not true.

So, no solution

You would earn $0.94 for recycling the tomato can.
I’m assuming you need to find the surface area first to get the total amount of square inches.
The area of the base is 12.56 square inches using the formula for area of a circle. Double it for both bases. 12.56 + 12.56 = 25.12 square inches.
Then the height times the circumference to get the square inches for the round side. 5.5 times 12.56 (which is the circumference and area of the base) equals 69.08 square inches.
And add 69.08 and 25.12 to get 94.2 square inches.
Now you get $0.01 for every full square inch, which would give you $0.94 for recycling the tomato can.
you will earn 0.94 have a great day

In the diagram, line GH is perpendicular to line IJ. What is the measure of angle 1?


A. 37°
B. 53°
C. 63°
D. 74°

Answers

Answer: B

Explanation: 37+53= 90 and it being perpendicular creates a right angle of 90 degrees
Answer is 53 because these are supplementary angles and they adapt to 180 degrees. You add 37 and 90= 127, and then you subtract 127 from 180.
