Answer:

A. -16x²+64x+8

B. 72 ft.

Step-by-step explanation: A. Expand the perfect square binomial -16(x²-4x+4)+72, dist. -16 (-16x²+64x-64+72), then combine like terms (-16x²+64x+8)

B. Find the abs. max. by looking back at the vertex form. The max is (2,72). Use the y-value for the height.

The probability that it will weigh less than 23.1 ounces is = 0.8643

P(x < 23.1)

= P[(x - \mu) / \sigma < (23.1 - 22) / 1]

= P(z < 1.1)

Using the z table,

= 0.8643

Probability is the branch of arithmetic concerning numerical descriptions of ways in all likelihood an occasion is to occur, or how likely it is that a proposition is authentic. The chance of an occasion is a variety of between zero and 1, where, roughly talking, 0 indicates the impossibility of the event, and 1 indicates truth.

The possibility of an event may be calculated through probability formulation by using simply dividing the favorable wide variety of consequences by the overall range of viable consequences.

Opportunity = the number of ways of achieving achievement. the whole quantity of feasible results. for instance, the possibility of flipping a coin and it being heads is ½, because there's 1 way of having a head and the total wide variety of viable results is 2 (a head or tail). We write P(heads) = ½.

What is Meant by Significant Figures?

In Mathematics, the significant figures define the number of important single digits that contribute to the degree of accuracy of the given number. The five important rules for the significant figures are as follows:

All the non zero numbers are significant figures

The zero present in between the non zero numbers are significant figures

The leading zeros are not significant

The trailing zeros present at the right side of the decimal point are significant figures

Trailing zeros of the number without a decimal point are not significant figures

The trailing zeros present in the whole number with the decimal point are significant figures
