If 30.s g of milk contains 18 C, how many
Calories will you consume by drinking a glass
of milk (244 g)?

Answers

Answer:

the answer would be (244/30.5) x 18, so the answer should be 144!

Step-by-step explanation:

Put me the brainest. thanks

if 30.5 g contains 18 cal then
30.5÷18 would tell how much calories are in 1 g which is 1.6944.
therefore to find how much would be in 244 g you would multiply 244 by 1.6944 which would be 413.4 calories

A researcher asked five of his doctor friends if they thought the new Brand X medicine that he
developed was effective. Four responded "yes." The researcher used the results to write a TV
advertisement claiming that "4 out of 5 doctors prefer Brand X medicine." Is this a valid inference?
Explain.
Use pencil and paper. Explain all of the factors that are necessary for an inference to be valid.
Is the inference valid? Explain. Choose the correct answer below.
OA. No, because the doctors asked are not a representative sample of the population of doctors.
OB. No, because 4 doctors said yes out of 9 who were asked.
OC. Yes, because 4 doctors said yes out of 5 who were asked.
OD. Yes, because the doctors asked are a representative sample of the population of doctors.

Answers

Answer:

Step-by-step explanation:

First of all, this is not math its common sense

4/5 is just an ifference. in order to prove this, the general term would be asking a factor of the doctors such as 10, and then ask.

To prove this , use algebra.

4x/5x

Shorten to 1

0.8x/1x

So you would theoretically be getting infinite amounts of doctors. but still 4/5 of them will say yes.

This is false because N0 is a cardinal number system where is omega is a ordinal.

asking five people is indefinitely not enough to determine a representatoive sample of every doctor in the world.

Find the mean, median mode and range of: 75, 80, 60, 90, 85, 80, -7, 90, 70, 65

Answers

Answer:

Mean: 68.8.

Median: 77.5

Mode: 80, 90

Step-by-step explanation:

-7 + 60 + 65 + 70 + 75 + 80 + 80 + 85 + 90 + 90 = 688. Then divide by 10 because there are 10 numbers.

-7 + 60 + 65 + 70 + 75 + 80 + 80 + 85 + 90 + 90

(75, 80) are the middle numbers, so add them both, then divide by 2.

80, 90 appear more than the other numbers.

Range is highest - lowest. 90 - (-7) = 97, or it could be 83. I don't know.

The mean is 68.8

The median is 77.5

The mode is 80 and 90

The range is 97

Rory would finish reading first, I’ve done the math for you ^^

Rory would finish first!
To find the amount of pages they read you divide the amount of pages by the time
140/5 = 28
200/7.5 = 26.6
To find how long it would take them you take the number of pages they need and divide it by there average amount of pages per hour
350/28 = 12.5 hrs
350/26.6 =13.2 hrs

Alexander’s parents are saving for his college fund. They put $8,000 into an interest-bearing account with an annual compound interest rate of 4.5%.

Alexander’s parents want to determine what the balance of his college fund account will be after 12 years.

Which formula would be used for this situation?
A = (8,000 + 0.045)12
A = 8,000(1 + 0.045)12
A = 8,000(1 + 0.12)4.5

(adding more to this but since the question only asked for one answer this should be enough!)

Step-by-step explanation:

a : 59

b : 59

c : 121

d : 121

f : 59

g : 90

h : 59

j : 31

k : 31 (everything in bold is uncited knowledge from me doing this years ago :,)

m : 90

so g must = 90 because not only is it in a right triangle, but also the corner of the rectangle. this goes for hk, m and jf, they all must add up to 90.

given a = 59 we can also find d from this, as it must add up to 180.

then adding g [90] + a [59] we get 149, which we then subtract from 180 to get j.

we get 31 from that and can now subtract 90 from that to find f, which is also 59, so f=59.

A bicycle tire has a radius of 26 inches. How many revolutions will this tire make if the bicycle is pedaled 1 mile? (Use 3.14 for and 1 mile = 5280 feet). Science Mysteries: Why Do People Yawn?Science has given humans many amazing devices and useful bits of knowledge. We know so much about our bodies and how to stay healthy, for example. We also know how to make machines and devices that make life easy for us. Scientists dedicate their lives to knowledge, but even with a lifetime commitment, sometimes scientists fail to find all the answers. One mystery that still remains unsolved is why we yawnwhat makes us yawn and what purpose it serves.Recent studies suggest that we yawn when we get tired as a way to encourage our brains. The theory is that yawning helps cool the brain, allowing it to work more efficiently. According to WebMD's article about these studies, when you yawn, your jaw muscles get stretched, increasing blood flow to your neck, face, and head. Also a deep breath during the yawn forces spinal fluid and blood down from the brain. The cool air then cools down these fluids.Other scientists believe, however, that yawning is a form of communication. This theory attempts to explain why yawning seems to spread from person to person. This kind of behavior is called "contagious yawning" and carries with it a possible social message. Scientists are not yet sure what exactly the message is, but they believe people who have more social empathy are more likely to start yawning when they see someone else yawning.Scientists will continue to investigate the mystery of the yawn. Is it a leftover behavior from before humans had language? Was it a "Hey, I'm sleepy. Let's go to sleep" message? Or is it really just a way to keep our brains cool? While this behavior still is largely a mystery, one thing is certain: you are probably fighting the urge to yawn right about now.Which word from the text best describes scientists' understanding of the yawn?
