How much ₹ each will get if 242.46₹ is distributed equally among the students

slavikrds [6]

Complete Question:

How much ₹ will each get if 242.46₹ is distributed equally among the 6 students

Answer:

Each of the 6 students will get ₹40.41

Step-by-step explanation:

Given

$Amount = 242.46$

$Students = 6$

Required

Determine how much each student gets

To do this, we simply divide the total amount by the number of students

i.e.

$Each\ Students = \frac{Amount}{Number\ Students}$

$Each\ Students = \frac{242.46}{6}$

$Each\ Student = 40.41$

Hence, each of the 6 students will get ₹40.41

"A supplier of digital memory cards claims that no more than 1% of the cards are defective. In a random sample of 600 memory car

Nady [450]

Answer:

Both the values fall in the critical region so we reject H0: p ≤ 0.01 and conclude that the results are significantly different from chance identification and it is not a sample fluctuation.

Step-by-step explanation:

1) Formulate the hypothesis

H0: p ≤ 0.01 against the claim Ha: p > 0.01

2) Choose the significance level ∝= 0.01

3) The test statistics under H0 is

z= x -np /√npq ( without continuity correction)

z= x ± 1/2 -np /√npq ( with continuity correction)

4) the critical region is z> ±2.33 because the alternate hypothesis is stated on greater than basis.

5)Computations:

Z= x -np /√npq ( without continuity correction)

Z= 6- 600( 0.03)/√ 600( 0.03)(0.97)

z= - 2.82 ( without continuity correction)

z= x ± 1/2 -np /√npq ( with continuity correction)

Z= (6-0.5)- 600( 0.03)/√ 600( 0.03)(0.97)

z= -12.5/4.1785

z= -0.29915 ( with continuity correction)

6) Both the values fall in the critical region so we reject H0: p ≤ 0.01 and conclude that the results are significantly different from chance identification and it is not a sample fluctuation.

What is the minimum value of the graph of y=sin x assumes

Alex

Short answer: - 1
The first thing you should do is draw this or get a program to do it. I use desmos. It is included. The graph shows one complete cycle every 2*pi intervals (or 360 degrees.)

You will find no lower value that y = - 1 (nor any value greater than y = 1)

For each function, find f(-1), f(0), and f(2). f(x)=4x-3 f(x)=1/2x+2

icang [17]

f(x)=4x-3
f(-1)=4(-1)-3=-4-3= -7
f(0)=4(0)-3= -3
f(2)=4(2)-3=8-3= 5

f(x)=1/2x+2 
f(-1)=1/2(-1)+2=1/(0)= unknown
f(0)=1/2x+2=1/2(0)+2=1/2
f(2)=1/2x+2=1/2(2)+2=1/6
