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

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

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.

1 x 8 = 8

Final answer: 8 square meters

Answer:

12

Step-by-step explanation:

Assuming the diagram is thesame as the one attached,

From the diagram,

Triangle ABC is similar to Triangle DEC

ΔABC is similar to ΔDEC

Note: In similar triangle, ratio of corresponding sides are equal

Therefore,

line(AB) /line(DE) = line(BC)/line(EC).................... Equation 1

Given: AB = 20, BC = 15, EC = BC-BE = (15-6) = 9

Substitute these values into equation 1 and solve for Line DE

20/DE = 15/9

DE = (20×9)/15

DE = 12.

Hence line DE = 12.

Answer:

[tex]DE=12[/tex]

Step-by-step explanation:

From the question we are told that:

 [tex]AB=20\\\\BC=15\\\\BE =6[/tex]

Generally the equation for the similar triangles is mathematically given by

  [tex]\frac{AB}{BC} =\frac{DE}{EC}[/tex]

Where

 [tex]EC = BC - BE \\\\EC= 15-6 \\\\EC= 9[/tex]

Therefore

 [tex]\frac{20}{15} =\frac{DE}{9}[/tex]

 [tex]\frac{20*9}{15} =DE[/tex]

 [tex]DE=12[/tex]

answer:

(a) 6:14

(b) 8:14

step-by-step explanation:

there are 8 red apples and 6 green apples

to find the ratio of red apples to all the apples and green apples to all the apples we must add 6+8= 14

(a) what is the ratio of green apples to all the apples in the basket?

14-8=6

so the ratio of green apples to all the apples in the basket is 6:14

(b) what is the ratio of red apples to all the apples in the basket?

14-6=8

so the ratio of red apples to all the apples in the basket is 8:14

how big are the cups????

Division is one of the four fundamental arithmetic operations. The number of cups of water that Billy will use to fill a 9-litre bucket is 9.

The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

Given that a cup holds 1 litre of water. Therefore, The number of cups of water that Billy will use to fill a 9-litre bucket is,

Number of cups = 9 liters / 1 liter

                           = 9

The number of cups of water that Billy will use to fill a 9-litre bucket is 9.
