Answer:

4 players and 1 instructor

Step-by-step explanation:

If all 4 players pay $300 each, that equals $1,200. The instructor will get $1,000 of it. That means there is $200 left. They need 40 balls per player. Each ball is $1, so that's $40 per player. 40 x 4= 160    200-160 = 40 The club will have $40 left.

Answer:

The next three terms of the sequence are 17, 21 and 25.

The 300th term of the sequence is 1197.

Step-by-step explanation:

The statement describes an arithmetic progression, which is defined by following formula:

p(n) = p_{1}+r\cdot (n-1) (1)

Where:

p_{1} - First element of the sequence.

r - Progression rate.

n - Index of the n-th element of the sequence.

p(n) - n-th element of the series.

If we know that p_{1} = 1, n = 2 and p(n) = 5, then the progression rate is:

r = \frac{p(n)-p_{1}}{n-1}

r = 4

The set of elements of the series are described by p(n) = 1 + 4\cdot (n-1).

Lastly, if we know that n = 300, then the 300th term of the sequence is:

p(n) = 1 + 4\cdot (n-1)

p(n) = 1197

And the next three terms of the sequence are:

n = 5

p(n) = 1 + 4\cdot (n-1)

p(n) = 17

n = 6

p(n) = 1 + 4\cdot (n-1)

p(n) = 21

n = 7

p(n) = 1 + 4\cdot (n-1)

p(n) = 25

The next three terms of the sequence are 17, 21 and 25.

The 300th term of the sequence is 1197.

madam [21]

Answer:

a) 0.705

b) 0.976

c) 0.01

d) 0.09

Step-by-step explanation:

We have to find the area under the standard normal curve.

a) area under the standard normal curve that lies outside the interval between z= −1.98 and z=0.61.

=P(-1.98

b) area under the standard normal curve to the left of z=1.98

=P(z

c) area under the standard normal curve to the right of z= 2.34

P(z>2.34)\\=1 - P(z

d)  area under the standard normal curve that lies between z= −0.94 and z= −0.63

=P(-0.94
