Answer:

Number of people that can be served 7 ladles = 100 people

Step-by-step explanation:

We are told that;

Initial number of ladles proposed per person = 5

Number of persons to be fed based on 5 ladles = 140 persons

Thus, amount of ladles based on that data is;

140 people x 5 ladle/1 person = 700 ladles full of soup

Now, since the cook decides to give 7 ladles full of soup to each person, the number of people that can be fed will now be;

700 ladles ÷ 7 ladles/person = 100 persons

What is 1.83 as a mixed fraction

lora16 [44]

Answer:

$1\frac{83}{100}$

Step-by-step explanation:

First of all, the number before the decimal would be the whole number of the fraction.

So, $1\frac{?}{?}$

Then, you would put 0.83 over a fraction.

So because you cannot simplify it anymore, it would be $1\frac{83}{100}$

Brynn and Denise launch their rockets at the same time. The height of Brynn’s rocket, in meters, is given by the function f(x)=-

Vladimir [108]

Answer:

The height of rocket is 102.7 meter.

Step-by-step explanation:

Given : Brynn and Denise launch their rockets at the same time.

The height of Brynn’s rocket, in meters, is given by the function $f(x)=-4.9x^2+75x$ , where x is the number of seconds after the launch.

The height of Denise’s rocket, in meters, is given by the function

$g(x)=-4.9x^2+50x+38$ , where x is the number of seconds after the launch.

There is a moment when the rockets are at the same height.

To find : The height

Solution :

When the rockets have same height

So, $f(x)=g(x)$

$-4.9x^2+75x=-4.9x^2+50x+38$

$-4.9x^2+75x+4.9x^2-50x=38$

$25x=38$

$x=\frac{38}{25}$

$x=1.52$

Now, we put x value in any of the function to find height.

$f(x)=-4.9x^2+75x$ , x=1.52

$f(x)=-4.9(1.52)^2+75(1.52)$

$f(x)=-11.32096+114$

$f(x)=102.67$

Nearest tenth = 102.7

Therefore, The height of rocket is 102.7 meter.

A music website tracked the number of new users per day over 1 week. The number of new users for each day of the 7 days was 38,

Part a)

MAD = median of absolute deviations

MAD = median of the set formed by : |each value - Median|

Then, first you have to find the median of the original set

The original set is (<span>38, 43, 45, 50, 51, 56, 67)

The median is the value of the middle (when the set is sorte). This is 50.

Now calculate the absolute deviation of each data from the median of the data.

1) |38 - 50| = 12
2) |43 - 50| = 7
3) |45 - 50| = 5
4) |50 - 50| = 0
5) |51 - 50| = 1
6) |56 - 50| = 6
7) |67 - 50| = 17

Now arrange the asolute deviations in order

(0, 1, 5, 6, 7, 12, 17)

The median is the value of the middle: 6.

Then the MAD is 6.

Part b) MAD represents the median of the of the absolute deviations from the median of the data.
