Answer:

\frac{1681}{4}

or

105 \frac{1}{4}

Step-by-step explanation:

10 \frac{  +  1}{ \times 4}

10×4=40+1=41, that will be your numerator (number at the top of the fraction) and the denominator 4 will stay the same. (bottom number)

\frac{41}{4}

the base and the height will remain the same.

Formula : base × height = Area

\frac{41}{4}  \times  \frac{41}{4} =  \frac{1681}{16}

16 goes into 1681 105 times remainder 1.

so as a mixed number it will be

105  \frac{1}{4}

The surface area of sphere T is 452.16 units squared. The surface area of sphere X is 1808.64 units squared. how many times larg
Art [367]

Answer:

the radius of sphere X is 2 times larger than the radius of sphere T

Step-by-step explanation:

Given

Surface area of sphere, T =452.16

Surface area of sphere, X= 1808.64

how many times larger is the radius of sphere X than the radius of sphere T?

Finding radius of both spheres:

Surface area of sphere is given as

A=4πr^2

Now putting value of Ta=452.16 in above formula

452.16=4πrt^2

rt^2=452.16/4π

rt^2=35.98

Taking square root on both sides

rt=5.99

Now putting value of Xa=1808.64 in above formula

1808.64=4πrx^2

rx^2=1808.64/4π

rx^2=143.92

Taking square root on both sides

rx=11.99

Comparing radius of sphere X and the radius of sphere T

rx/rt=11.99/5.99

      = 2.00

rx=2(rt)

Hence the radius of sphere X is 2 times larger than the radius of sphere T!

velikii [3]

Answer:

Because we don't know the exact shape of the population distribution since they are not Normally distributed and they are also not very non-Normal

Step-by-step explanation:

We are given;

Population standard deviation;μ = 200

Population standard deviation; σ = 35

Sample size; n = 30

We are told that the weights are not Normally distributed and they are also not very non-Normal. Therefore it means we don't know the exact shape of the population distribution and as such we can't calculate the probability that a randomly selected passenger weighs more than 200 pounds.
