here are the first five terms of a quadratic sequence (1 8, 21, 40, 65). the nth term of this sequence can be written in the for
bazaltina [42]

Answer:

a=3 and b=-2

Step-by-step explanation:

We are given that five  terms of a quadratic sequence are

1 8, 21, 40, 65.

The nth term of this sequence

=an^2+bn

We have to find the value of a and b where a and b are integers.

For n=1

a+b=1   ......(1)

For n=2

(2)^2a+2b=8

4a+2b=8

2a+b=4   .....(2)

Subtract equation (1) from (2) we get

2a-a=4-1=3

a=3

Using the value of a=3 in equation (1)

3+b=1

b=1-3=-2

Hence, the value of

a=3 and b=-2

A certain chalkboard manufacturer determines that their largest blackboard model has a mean length of 5.00 m and a standard devi
Igoryamba

Answer:

23 chalkboards

Step-by-step explanation:

Given:

Mean length = 5 m

Standard deviation = 0.01

Number of units ordered = 1000

Now,

The z factor = \frac{\textup{x - Mean}}{\textup{standard deviation}}

or

The z factor = \frac{\textup{4.98 - 5}}{\textup{0.01}}

or

Z = - 2

Now, the Probability P( length < 4.98 )

Also, From z table the p-value = 0.0228

therefore,

P( length < 4.98 ) = 0.0228

Hence, out of 1000 chalkboard ordered (0.0228 × 1000) = 23 chalkboard are likely to have lengths of under 4.98 m.
