Answer:

Option (6)

Step-by-step explanation:

Name f the planes of the figure given,

Plane JKL or plane Z

Plane PSR

Plane PQK

Plane SRL

Plane PSM

Plane QRL

Therefore, the number of planes of the box standing vertical on a table are 6.

Option (6) will be the answer.

mixer [17]

Answer:

42.49 unit price

Step-by-step explanation:

The average price function, S(ave), will be an integral of the price function over the period of time (6 years), that is

S(ave) = $1/6*\int\limits^6_0 {S(t)} \, dt$

= $1/6*\int\limits^6_0 {37+6e^-0.03t} \, dt$

Solving the integral, we have

S(ave) = 1/6*(37t - (6e^-0.03t)/0.03) with the limits being from t = 0 to t = 6

Hence, we have

S(ave) = $37 - \frac{200}{6}*(e^(-0.03*6) - 1)$

This resolves to 42.49 unit price

Feliz [49]

Answer:

test stat=1.7986

p value =0.0391

Step-by-step explanation:

given

n=50

d = 7.3

s d = 28.7

formula to calculate test statistic

t= $\frac{d}{\frac{s d}{\sqrt{n} } }$

⇒ t= $\frac{7.3}{\frac{28.7}{\sqrt{50} } }$

⇒t=1.7986

for 49 df and t=1.7986 ,p value can be obtained from software

p value=0.0391

A turtle population grows in a manner that closely resembles a geometric sequence. Given the table of values, determine the turt

AleksandrR [38]

The turtle population will be 486 after 5 years.

Step-by-step explanation:

The general form of a geometric progression or geometric sequence is a, ar, ar², ar³ and so on.

where,

a = first term
r = common ratio

The formula to find the nth term in GP is :

nth term = $ar^{n-1}$

The given sequence 6,18,54.

In this sequence,

The first term, a = 6
The common ratio, r = 18/6 = 3

5th term = $6\times3^{5-1}$

⇒ $6\times3^{4}$

⇒ 6 $\times$ 81

⇒ 486

Therefore, after 5 years the population will be 486.

What is the probability that a card picked at random from a 52-card deck of playing cards is a club or a jack?

Anestetic [448]

The probability is given as No of favourable outcomes over total number of events. Now, the no of clubs in a deck of cards is 13 and similarly, the number of jacks in a deck of cards is 13. Then, the probability that a card picked at random from a 52-card deck of playing cards is a club or a jack = 13+13/52 = 26/52 = 1/2 = 50%
