gladu [14]

Answer:

The surface area of the structure is SA=2,500\pi\ m^{2}

Step-by-step explanation:

we know that

The surface area of a sphere is equal to

SA=4\pi r^{2}

In this problem we have

r=50/2=25\ m -----The radius is half the diameter

substitute

SA=4\pi (25)^{2}

SA=2,500\pi\ m^{2}

Ksivusya [100]

\frac{147}{168}  =  \frac{x}{100}
147×100=14700
168×x=168x
14700÷168=87.5
100-87.5=12.5

on a popular fictional game show, contestants are given the opportunity to win money by reaching into a bag after being blindfol
labwork [276]

Construct a probability mass function (pmf) for x, the dollar amount won by a contestant in this game is 1/18.

What is a probability math example?

  • Probability is the measurement of how likely something is to happen.
  • As an example, since there is only one way to get a head and a total of two possible results, the likelihood of flipping a coin and getting heads is one in two. a tail or a head.
  • We write P(heads) = 12 here. The four most popular approaches to probability are axiomatic, classical, empirical, and subjective.

from above total number of chips =4+6+5+2+1 =18

hence Probabilty of win 0 P(0)=4/18

P(1) =6/18

P(5) =5/18

P(10) =2/18

P(100)=1/18

x     P(x)     xP(x)

0    0.22     0.00

1     0.33      0.33

5     0.28       1.39

10      0.11       1.11

100     0.06      5.56

                       8.39

therefore expeted value =8.39

A carts initial velocity is + 5.0 meters per second. What is it’s final velocity after acceleration at the rate of 2m/s2 for 10.
MrMuchimi

Answer:

25m/s

Step-by-step explanation:

Here,

Initial velocity(u) = 5.0 m/s2

acceleration(a)= 2m/s2

time taken(t)=10.0 s

final velocity (v)=?

Now,

v=u+at

=5.0+2*10.0

= 25m/s
