During a race sample of five sports cars has a mea speed of 175mph. The speeds in miles per hour of cars are 186,181,170,151, find the speed of the five car
Answer:
Speed of 5th car = 187 mph
Step-by-step explanation:
Given:
Mean speed of five car = 175 mph
Speed of four cars = 186,181,170,151 mph
Find:
Speed of 5th car
Computation:
Average mean = Sum of all observation / Number of observation
Mean speed of five car = Sum of five cars speed / Number of cars
175 = [186 + 181 + 170 + 151 + Speed of 5th car] / 5
186 + 181 + 170 + 151 + Speed of 5th car = 175 x 5
186 + 181 + 170 + 151 + Speed of 5th car = 875
688 + Speed of 5th car = 875
Speed of 5th car = 875 - 688
Speed of 5th car = 187 mph
Ysaac, médico de turno en una clínica local, deja encargado a la enfermera Elisa la dosis de Panadol (mg) para todos los pacientes del hospital. La enfermera le pregunta ¿cuál es la Dosis?, y el médico le responde que la dosis anterior empleada en total para 10 pacientes adultos se encontraba resolviendo la ecuación x2+ 50x – 2400 = 0. Si la dosis actual ha disminuido en 10 miligramos para cada paciente. ¿Cuánto debe ser la dosis para cada paciente adulto actualmente?
Answer:
Each adult patient today taking dose of 13 mg.
Step-by-step explanation:
Given - Ysaac, a doctor on duty at a local clinic, leaves the Panadol dose (mg) to nurse Elisa for all hospital patients. The nurse asks him what is the Dose ?, and the doctor answers that the previous dose used in total for 10 adult patients was solving the equation x2 + 50x - 2400 = 0. If the current dose has decreased by 10 milligrams for each patient.
To find - How much should the dose be for each adult patient today?
Solution -
Given that, the equation is -
x² + 50x - 2400 = 0
⇒x² + 80x - 30x - 2400 = 0
⇒x(x + 80) - 30(x + 80) = 0
⇒(x - 30)(x + 80) = 0
⇒x = 30, -80
But dose can not be negative
So, x = 30
∴ we get
The previous dose is 30 that is given to 10 patients
So,
1 patient is taking 3 mg previous dose
Now,
Given that,
If the current dose has decreased by 10 milligrams for each patient.
So,
The current dose = 3 mg + 10 mg
= 13 mg
⇒The current dose = 13 mg
∴ we get
Each adult patient today taking dose of 13 mg.

Answer:
8
Step-by-step explanation:
the rectangles length is 1 because 2^0 = 1
the width is 8 because 2^3 which is also 2 x 2 x 2 = 8
to find the area it would be length times width.

what is the relative frequency of students speaking spanish?
Answer:
Step-by-step explanation:
add all of them up, Julie, 6 + 12 + 3 + 4 = 25
there are 25 total students. now divide each of the number of people that speak that language by the total students
6/25 = .24 = 24%
12/25= .45 = 48%
3/25 = .12 = 12%
4/25 = .16 = 16%
Also, if you want to just check, see if the percentages add to 100%
Using the relative frequency concept, it is found that the relative frequencies for students speaking each language is:
Arabic: 0.24Spanish: 0.48German: 0.12Vietnamese: 0.16--------------------------------
A relative frequency of a to b is a/b, that is, the number of desired outcomes divided by the number of total outcomes.
--------------------------------
6 + 12 + 3 + 4 = 25 students.6 speak Arabic, thus, the relative frequency of students speaking Arabic is 6/25 = 0.24.12 speak Spanish, thus, the relative frequency of students speaking Spanish is 12/25 = 0.48.3 speak German, thus, the relative frequency of students speaking German is 3/25 = 0.12.4 speak Vietnamese, thus, the relative frequency of students speaking Vietnamese is 4/25 = 0.16.A similar question is given at https://brainly.com/question/20630951

Drag each tile to the correct box. A data set that consists of many values can be summarized using the five-number summary. Arrange these five values in order from least to greatest.
Answer:
Minimum < Q1 < Median < Q3< Maximum
Step-by-step explanation:
Given
Minimum, Median, Maximum, Q3 and Q1
See attachment for complete question
Required
Order from least to greatest
In a dataset, the range is:
[tex]Range = Maximum - Minimum[/tex]
This implies that, the minimum is the least and the maximum is the highest of the dataset
So, we have:
Minimum < < < < Maximum
The median is the middle item; So, the above becomes
Minimum < < Median < < Maximum
In a dataset, the IQR is:
[tex]IQR = Q_3 - Q_1[/tex]
This implies that:
[tex]Q_3 > Q_1[/tex]
So, we have:
Minimum < Q1 < Median < Q3< Maximum
What is the median of the data set represented by the box plot below?

Step-by-step explanation:
I believe that would be 1025.4cm³
A box plot is shown below what is the median and q3 of the data set represented on the plot median=30;q3=44 median 36; q3=44 median 30;q3=39 median = 36;q3=39
The required boxplot isn't attached, an hypothetical solution is given which could be applied to solve your actual task.
Answer:
Kindly check explanation
Step-by-step explanation:
From the attached picture, the median and upper quartile value of the boxplot are :
The median of a dataset plotted on a box and whisker plot can be obtained directly from the plot as the point where a vertical line splits the box. The line inside the box gives the median of the data. The Q3 value which is the upper quartile is depicted on the box and whisker plot as the endpoint of the box. The endpoint of the box gives the upper quartile value for the dataset.
In the attached boxplot , the median = 29
The upper quartile = 38
