Calculate an estimate for the mean temperature
disa [49]
The temperature was in the range of 10-13 on 7 of the days.
Give it the weight of the middle of the range = 11.5 for 7 times = 80.5

The temperature was in the range of 14-17 on 9 of the days.
Give it the weight of the middle of the range = 15.5 for 9 times = 139.5

The temperature was in the range of 18-21 on 16 of the days.
Give it the weight of the middle of the range = 19.5 for 16 times = 312

The temperature was in the range of 22-25 on 22 of the days.
Give it the weight of the middle of the range = 23.5 for 22 times = 517

The temperature was in the range of 26-29 on 6 of the days.
Give it the weight of the middle of the range = 27.5 for 6 times = 165

Total weight for all ranges = (80.5 + 139.5 + 312 + 517 + 165) = 1,214

Total number of days = 60

Estimated mean temperature = (1,214) / (60) = <u>20.23°C </u>

Can someone simplify
Rashid [163]

Answer:

Option (2). 2\frac{1}{4}

Step-by-step explanation:

The given expression is [-5\frac{1}{4}-(-7\frac{1}{2})]

We can rewrite the fractions as,

-5\frac{1}{4} = -(5+\frac{1}{4})

-7\frac{1}{2}=-(7+\frac{1}{2})

Now we will substitute the fractions in the expression,

[-(5+\frac{1}{4})]-[-(7+\frac{1}{2})]

= -(5+\frac{1}{4})+(7+\frac{1}{2})

= (-5 + 7) + (-\frac{1}{4}+\frac{1}{2})

= 2 + \frac{2-1}{4}

= 2 + \frac{1}{4}

= 2\frac{1}{4}

Therefore, Option (2). will be the answer.

1 half dollar + 1 quarter - 2 dimes
Eduardwww [97]

Answer:

55 cents.

Step-by-step explanation:

First, we start off with a half dollar (50 cents), and add a quarter (25 cents). 50 + 25 = 75. Next we take two dimes (each dime being 10 cents). 10 + 10 is 20, so we have twenty cents in dimes. It says to subtract the 2 dimes from our current number 75 minus 20 is 55. Therefore, we have 55 cents left. (If needed, that is 1 half dollar and 1 nickel.)

Hope this helps! :D
