What is photosynthesis ?<br>what is pain ?<br>​
Aloiza [94]

Answer:

photosynthesis is the process by which plants use energy from the sun in order to produce energy such as glucose. It mainly uses energy from the sun, carbon dioxide, and water to achieve this.

Pain is a warning signal produced by your body and sent to the central nervous system to tell you of a physical injury. Your body has many pain receptors that can be triggered by a myriad of things like heat or punctures.

The freshmen competed with the sophomores to see who could raise the most money by recycling. The appropriate design for testing
brilliants [131]

Answer:

Independent-samples t-test.

Step-by-step explanation:

We are looking for the appropriate design for testing the significance of the difference between the means.

Now, there is a parametric test known as the Independent Samples t Test and what this test does is that it compares the mean of two independent groups in order to find out whether there is statistical evidence that the related population mean is significantly different.

Thus, the test to be used here is Independent-samples t-test.

Use rounding to estimate the product
sdas [7]

Answer:

The estimate of the product is about 35 answer C

Step-by-step explanation:

- We use rounding to estimate the product of two fractions

- The mixed number has whole number and fraction

- To round the mixed number we look to the fraction

- If the numerator is half or greater than half the denominator, then we

  add the whole number by 1 and cancel the fraction

- If the numerator is less than half the denominator, then we keep the

  whole number as it and cancel the fraction

- Ex: If the mixed number is 2\frac{3}{4}, 3 is more than

 half 4 then we will add 2 by 1 and cancel the fraction part, the

 mixed number 2\frac{3}{4} after rounding is 3

- Ex: If the mixed number is 5\frac{1}{4}, 1 is less than

 half 4 then we will keep 5 as it and cancel the fraction part, the

 mixed number 5\frac{1}{4} after rounding is 5

* Lets solve the problem

∵ In the part 4\frac{3}{4} 3 is more than half 4

∴ The rounding value of 4\frac{3}{4} is 5

∵ In the part 7\frac{2}{17} 2 is less than half 17

∴ The rounding value of 7\frac{2}{17} is 7

∴ 4\frac{3}{4}*7\frac{2}{17}=5*7=35

* <em>The estimate of the product is about 35</em>
