Many urban zoos are looking at ways to effectively handle animal waste. One zoo has installed a facility that will transform ani

lukranit [14]

Answer:

Option A: 0.484

Explanation:

The amount of animal waste one zoo is diposing daily is approximately normal with:

mean, μ = 348.5 lbs
standard deivation, σ = 38.2 lbs

The proportion of waste over 350 lbs may be found using the table for the area under the curve for the cumulative normal standard probability.

First, find the z-score for 350 lbs:

$z-score=\dfrac{X-\mu}{\sigma}$

$z-score=\dfrac{350lbs-348.5lbs}{38.2lbs}\approx0.04$

There are tables for the cumulative areas (probabilities) to the left and for the cumulative areas to the right of the z-score.

You want the proportion of the days when the z-score is more than 0.04; then, you can use the table for the values to the rigth of z = 0.04.

From such table, the area or probability is 0.4840.

The attached image shows a portion of the table with that value: it is the cell highlighted in yellow.

Hence, the answer is the option (A) 0.484.

Graph the number -3/4

MAVERICK [17]

Given : number -3/4 - and number line

To Find : represent -3/4 - on number line

Solution:

Numbers with a negative sign are less than zero

Right of zero represented by ‘+’ sign and to the left of zero represented by ‘–’ sign.

+ sign numbers can be denoted as simply numbers

On a number line the number increases as we move to the right and decreases as we move to the left.

1 : Draw a line and mark some points at equal distance on it

Mark a point as zero on it. Points to the right of zero are positive integers and are marked simply 1, 2, 3 and so on , while points to the left of zero are negative integers and are marked – 1, – 2, – 3 and so on

- 3/4

Divide number line between -1 & 0 in 4 Equal parts and go 3 part left of 0 to show - 3/4 on number line
