The height of water shooting from a fountain is modeled by the function f(x) = −4x2 + 24x − 29, where x is the distance from the

Komok [63]

Answer:

the maximum height of the water is 7 ft

Step-by-step explanation:

Using " ^ " to indicate exponentiation, we have −4x^2 + 24x − 29.

Rewrite -4x^2 + 24x as -4(x^2 - 6x) and then complete the square of (x^2 - 6x). We get:

(x^2 - 6x + 9 - 9), which is exactly equivalent to (x^2 - 6x).

Going back to the original equation: −4x^2 + 24x − 29, or

−4(x^2 - 6x) − 29.

Now replace (x^2 - 6x) with (x^2 - 6x + 9 - 9):

-4(x^2 - 6x + 9 - 9) - 29, which simplifies to:

-4(x - 3)^2 + 36 - 29, or

-4(x - 3)^2 + 7, whose vertex is (3, 7). Thus, the maximum height of the water is 7 ft.

The weight of an organ in adult males has a bell-shaped distribution with a mean of 310 grams and a standard deviation of 40 gra

lara [203]

Answer:

Step-by-step explanation:

Given that:

The mean μ = 310

The standard deviation σ = 40

Using the empirical rule to determine the following :

a. About 95 % of organs will be between what weights?

At 95% data values lies within 2 standard deviations of mean.

Thus, the required range is :

= μ ± 2σ

= ( 310 - 2 (40) , 310 + 2(40) )

= (230, 390)

b. What percentage of organs weighs between 270 grams and 350 grams

Here:

μ ± σ = (310 - 40, 310 + 40)

μ ± σ = (270, 350)

Using empirical rule, 68% data values is in the range within 1 standard deviation of mean. This implies that 68% data values lie between (270, 350).

c. What percentage of organs weighs less than 270 grams or more than 350 grams?

The complement theorem can be use to estimate the percentage of organs that weighs less than 270 grams or more than 350 grams,

This can be illustrated as :

= 100 % - 68 %

= 32 %

d. What percentage of organs weighs between 230 grams and 430 grams?

Using the empirical rule:

The percentage of organs weighs between 230 grams and 430 grams is:

u - 2σ and u + 3σ respectively.

joe, adam and laura are driving up north to a cabin for the weekend. the trip is 65 miles round trip. joe drove for 20 miles, ad

ivann1987 [24]

With percentage in the question, you divide the miles they drove by the total miles in the trip (and of course multiply it by 100).
Joe:
$\frac{20}{65} =.3077$
.3077 times 100= 31% (just rounded the percentage to the nearest whole number).
Adam:
$\frac{35}{65} =.5385$
.5385 times 100= 54%
Laura:
$\frac{10}{65} =.1538$
.1538 times 100= 15%
Tell me if this helps!!
