Using Normal Distribution, what is the area to the right of 0.72 under the
natima [27]

Answer: 0.2358

Step-by-step explanation:

Using Normal Distribution, under the  standard normal curve

The area to the right of z is given by P(Z>z)=1-P(Z<z)

So, the area to the right of z= 0.72 under the  standard normal curve would be:

P(Z>0.72)=1-P(z<0.72)

=1-0.7642   [By using p-value table]

= 0.2358

Hence, the area to the right of z= 0.72 under the  standard normal curve is 0.2358 .

Sophia expects the number of cows, C C, on her farm t t years from now to be modeled by the function C ( t ) = 3 0 ( 2 ) C(t)=30
topjm [15]

Answer:

The expression is given as:

H(t)=C(t)\times F(t)=240\times 3^t.

Step-by-step explanation:

Sophia expects the number of cows, C, on her farm t years from now to be modeled by the function:

C( t ) = 30\times (2)^t

Additionally, she expects the supply of hay, F, in tons, that her crops can provide for each cow t years from now to be modeled by the function

F( t ) =8\times (1.5)^t

Let H be the total yearly amount of hay produced in Sophia's farm (in tons) t years from now.

Total amount of Hay produced in sophia's farm= Number of cows in farm×Amount of hay required for each cow.

i.e. H(t)=C(t)×F(t)

H(t)=30\times 8\times (2)^t\times (1.5)^t

and we know that a^x\times b^x=(a\times b)^x=(ab)^x

Hence,H(t)=240\times (2\times 1.5)^t\\\\H(t)=240\times 3^t.

Hence, the hay produced on Sophia's farm is used exclusively to feed her cows i.e. we need to write the formula of H ( t ) in terms of C(t) and F (t) is:

H(t)=C(t)\times F(t)=240\times 3^t.

Suppose that K is a random variable. Given that Upper P (negative 3.95 less than or equals Upper K less than or equals 3.95 )equ
Irina-Kira [14]

Answer:

P [ K > 3.95] = 0.5633

Step-by-step explanation:

The interpretation of the given question goes thus;

Suppose that K is a random variable

P[-3.95 ≤ K ≤ 3.95] = 0.725  

where; P [ + 3.95 < K ] = P [K < - 3.95]

P[K< 3.95] - P [K > - 3.95] =0.725

P [K < 3.95] - [ 1- P[K < 3.95]] = 0.725

P[k < 3.95] - 1 + P [ K < 3.95] = 0.725

3.95 P [ K < 3.95] -1 = 0.725

3.95 P [ K < 3.95] = 1.725

P [ K < 3.95] = 1.725/3.95

P [ K < 3.95] = 0.4367

P [ K > 3.95] = 1 - P[K< 3.95]

P [ K > 3.95] = 1 - 0.4367

P [ K > 3.95] = 0.5633
