The scatterplot shows the time it takes for a new hot plate to boil various amounts of water, and one lab group’s attempt at a line of best fit. What feedback should another lab group give during a peer review of the work? The line of best fit is reasonable because it does not go through any points. The line of best fit is reasonable because it goes through the largest cluster of points. The line of best fit is not reasonable because it does not go through any points. The line of best fit is not reasonable because it has more points below it than above it.

Answers

Answer 1

Answer:

The feedback the other lab group should give is (d) the line of best fit is not reasonable because it has more points below it than above it.

From the scattered plot (see attachment), we can see that the scattered plot has a total of 7 dots,

5 of which are below the line of best fit,
1 is on the line of best fit, and the other one is above it.

There are more points below the scattered plot, than above it.

This means that the scattered plot is not reasonable because of (d)

A pilot flew a jet from location A to B, a distance of 2500 meter,on the return trip the average speed was 20 percent faster than the outbound speed,the round-trip took 9 hours 10 minutes . What is the jet's speed from A to B.

Answers

Answer: The jet's speed from A to B would be 5.5 km/hr.

Step-by-step explanation:

Since we have given that

Distance = 2500 meter

Outbound speed be x

Average speed be $(100+20)/(100)x=(120)/(100)x=1.2x$

Time = 9 hours 10 minutes = $9(10)/(60)=9(1)/(6)=(55)/(6)$

According to question, it becomes,

$(2.5)/(x)+(2.5)/(1.2x)=(55)/(6)\n\n(1.2x+x)/(1.2x^2)=(55)/(6* 2.5)\n\n(2.2x)/(1.2x^2)=(11)/(3)\n\n(2.2)/(1.2x)=(11)/(3)\n\n2.2* 3=1.2x\n\n6.6=1.2x\n\n(6.6)/(1.2)=x\n\nx=5.5\ km/hr$

Hence, the jet's speed from A to B would be 5.5 km/hr.

Mario invested $6,000 in an account that pays 5% annual interest compounded annually. Using the formula A = P(1 + r)t, what is the approximate value of the account after 2.5 years?a. $6,075
b. $6,118
c. $6,456
d. $6,778

Answers

The approximate value of the account after 2.5 years is $6778.

Compound interest

The compound interest is given by:

A = P(1 + r)^t

where P is the initial amount, r is the interest rate, t is the period and A is the final amount.

Given that:

r = 5% = 0.05, P = $6000, t = 2.5 years, hence:

A = 6000(1 + 0.05) ^ 2.5 = $6778

The approximate value of the account after 2.5 years is $6778.

Find out more on Compound interest at: brainly.com/question/24924853

Given:
Principal = 6,000
interest rate = 5%
term = 2.5 years

A = P (1+r)^t
A = 6,000 (1 + 0.05)².⁵
A = 6,000 (1.05)².⁵
A = 6,000 (1.1297)
A = 6,778.20 Choice D.

If you buy 10 printers for your office and each printer costs $199, what is your cost for all 10?a. $2,990
b. $1,999
c. $1,990
d. $2,999

Answers

You buy: 10 printers
Each cost: $199
Total cost = ?

199 × 10 = total cost
199 × 10 = 1990
$1,990

This proves that c. $1,990 is your answer.

PLZ HELP! MATH >__<What is the lateral area of the rectangular prism with a base length of 14 m, a base width of 9 m, and a height of 6 m?
A. 264 m2
B. 276 m2
C. 528 m2
D. 756 m2

Answers

Lateral area = surface area not including the bases.

To find this area we just need to add up the area of all of those sides.

The 2 bases are the same area and defined by the length and width.

That leaves the 2 sides defined by length and height,
plus the 2 defined by width and height.

Of course, to find the area of a rectangle, we just multiply together its two dimensions.
length × height = 14 × 6 = 84
width × height = 9 × 6 = 54

2 × 84 + 2 × 54 = 276 m²

My answer would be 276m2

arun went for a movie nine days ago. he goes to watch movies only on thursdays. what day of the week is today? wednesday saturday friday sunday

Answers

Answer: What happened on saturday, add up the days on a notebook (make a chart) so you can figure out the rightful answer!!

Step-by-step explanation:

Today is Saturday.
Based on the information given, Arun goes to watch movies only on Thursdays. If he went for a movie nine days ago, we can count backwards from today to determine the day of the week it was.
Let's start counting backwards:
- Today is Saturday (Day 1)
- Yesterday was Friday (Day 2)
- Two days ago was Thursday (Day 3)
- Three days ago was Wednesday (Day 4)
- Four days ago was Tuesday (Day 5)
- Five days ago was Monday (Day 6)
- Six days ago was Sunday (Day 7)
- Seven days ago was Saturday (Day 8)
- Eight days ago was Friday (Day 9)
Therefore, if Arun went to watch a movie nine days ago, it was on a Friday.
