What does h(3.2) represent?

marshall27 [118]

Answer:

the height of the rock 3.2 seconds after it is propelled

Step-by-step explanation:

<u><em>The complete question is</em></u>

The function h(t) = –16t2 + 28t + 500 represents the height of a rock t seconds after it is propelled by a slingshot

Let

t------> the time in seconds

h----> the the height of a rock after it is propelled by a slingshot in meters

we know that

$h(t)=-16t^{2} +28t+500$

For $x=3.2\ sec$

Find the value of h(t)

$h(3.2)=-16(3.2)^{2} +28(3.2)+500=425.76\ meters$

therefore

h(3.2) represent the height of the rock $3.2$ seconds after it is propelled

see the attached figure to better understand the problem

If you have 66 data observations in a sample, how many classes (bins) does the sturges' rule recommend for you to construct a fr

Iteru [2.4K]

According to Sturge's rule, number of classes or bins recommended to construct a frequency distribution is k ≈ 7

Sturge's Rule: There are no hard and fast guidelines for the size of a class interval or bin when building a frequency distribution table. However, Sturge's rule offers advice on how many intervals one can make if one is genuinely unable to choose a class width. Sturge's rule advises that the class interval number be for a set of n observations.

Given,

n = 66

We know that,

According to Sturge's rule, the optimal number of class intervals can be determined by using the equation:

$k=1+log_{2} n$

Here, n is equal to 66 and by substituting the value to the equation we get:

$k=1+log_{2} (66)$

k = 7.0444

k ≈ 7

Carrie is buying bulk candy for a high school fundraiser. She buys 1000 candy bars for $350. What is the unit cost per candy bar

liubo4ka [24]

1000 candy bars ... $350
1 candy bar ... $x = ?

If you would like to know what is the unit cost per candy bar, you can calculate this using the following steps:

1000 * x = 350 * 1
1000 * x = 350 /1000
x = 350 / 1000
x = $0.35

Result: She can buy 1 candy bar for $0.35, so the correct result would be B) $.35.
