700 i think because 196 is close to 200 and 482 is close to 500 so 200+500=700

The estimated sum of 196 and 482 is 700.

We do estimates when we do mental calculation. We relate the number to the nearest number that can easily be computed mentally.

196 is near 200 so we round it up to 200
482 is near 500 so we round it up to 500

Thus, 200 + 500 = 700.

700 is the estimated sum.

The radius of one sphere is twice as great as the radius of a second sphere. Find the ratio of their volumes.
Juliette [100K]
The ratio of the radii is 2:1, so the ratio of their surface areas is 4:1. <span>The area of a sphere is defined by 4 * pi * r^2 </span>

<span>So if the radius of the first sphere is 2r, then it would be (2r)^2 = 4r^2 </span>

<span>The rest is the same. So the ratio of their surface areas would be </span>

<span>4 * pi * 4r^2 divided by </span>
<span>4 * pi * r^2 </span>

2. An exam readiness awareness taskforce at a Fremont National university sampled 200 students after the midterm to ask them whe
k0ka [10]

Answer:

c) (40+60+25)/200 or 63%

Step-by-step explanation:

n= 200 students

Did Well on the Midterm and  Studied for the Midterm = 75

Did Well on the Midterm and Went Partying = 40

Did Poorly on the Midterm and Studied for the Midterm = 25

Did Poorly on the Midterm and Went Partying = 60

The number of students that did poorly on the midterm or went partying the weekend before the midterm is given by the sum of all students who did poorly to all students who went partying minus the number of students who did Poorly on the Midterm and Went Partying:

N=(25+60)+(40+60) - 60\\N= 125

The probability that a randomly selected student did poorly on the midterm or went partying the weekend before the midterm is given by:

P = \frac{N}{n}=\frac{125}{200} = 0.63 = 63\%
