Volume of cone = $\pi$ r^2 h/3
r=2cm
h=9cm
cone = $\pi$ (2)^2 (9)/3 = 12 $\pi$ = 37.699
volume of hemisphere = 1/2 (4/3 $\pi$ r^3)
r=2cm
ice cream = 1/2 (4/3 $\pi$ (2)^3 = 5.3 $\pi$ = 16.755
12 $\pi$ +5.333 $\pi$ = 17.3333 $\pi$ = 52 $\pi$ /3
37.699 + 16.755 = 54.454

So your answers would be 54 cm^3 and 52 $\pi$ /3 cm^3

Atasha is solving the equation x^2-x=-3 with the quadratic formula.

AlekseyPX

Answer:

a= 1

b= -1

c= 3

Step-by-step explanation:

''a'' and "b" are the coefficients of x^2 and x respectively, where "c" is the constant number.

When solving a quadratic equation all the variables and constants should be on one side, in this case: x^2 -x +3=0.

Here the coefficient of x^2 is one, of x is -1 and constant is 3.

Consider two independent tosses of a fair coin. Let A be the event that the first toss results in heads, let B be the event that

aliina [53]

Answer with Step-by-step explanation:

We are given that two independent tosses of a fair coin.

Sample space={HH,HT,TH,TT}

We have to find that A, B and C are pairwise independent.

According to question

A={HH,HT}

B={HH,TH}

C={TT,HH}

$A\cap B=$ {HH}

$B\cap C$ ={HH}

$A\cap C$ ={HH}

P(E)= $\frac{number\;of\;favorable\;cases}{total\;number\;of\;cases}$

Using the formula

Then, we get

Total number of cases=4

Number of favorable cases to event A=2

$P(A)=\frac{2}{4}=\frac{1}{2}$

Number of favorable cases to event B=2

Number of favorable cases to event C=2

$P(B)=\frac{2}{4}=\frac{1}{2}$

$P(C)=\frac{2}{4}=\frac{1}{2}$

If the two events A and B are independent then

$P(A)\cdot P(B)=P(A\cap B)$

$P(A\cap)=\frac{1}{4}$

$P(B\cap C)=\frac{1}{4}$

$P(A\cap C)=\frac{1}{4}$

$P(A)\cdot P(B)=\frac{1}{2}\cdot \frac{1}{2}=\frac{1}{4}$

$P(B)\cdot P(C)=\frac{1}{4}$

$P(A)\cdot P(C)=\frac{1}{4}$

$P(A)\cdot P(B)=P(A\cap B)$

Therefore, A and B are independent

$P(B)\cdot P(C)=P(B\cap C)$

Therefore, B and C are independent

$P(A\cap C)=P(A)\cdot P(C)$

Therefore, A and C are independent.

Hence, A, B and C are pairwise independent.

tatuchka [14]

Answer:

f(x)=7x−4 f ( x ) = 7 x - 4. Replace f(x) f ( x ) with y y . y=7x−4 y = 7 x - 4. Interchange the variables. x=7y−4 x = 7 y - 4. Solve for y y .
