Using it's concept, it is found that there is a 0.6 = 60% probability that a student who does not have a cell phone is from grade 11.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

Researching the problem on the internet, it is found that there are 30 students with no cell phones, and of those, 18 are in grade 11, hence the probability is given by:

p = 18/30 = 0.6.

0.6 = 60% probability that a student who does not have a cell phone is from grade 11.

Answer:

∠1 = ∠5 (corresponding angle)

⇒∠5 = 50 deg

∠5+∠6=180 deg   (total sum is 180)

50+∠6=180

∠6=180-50

∠6=130

Step-by-step explanation:

∠5=86 (corresponding angle)

∠5=(4x+38) (vertically opp angle)

86=4x+38

4x=86-38

4x=48

x=12

Answer:

angle 1+angle 6=180(being exterior alternate angle)

50+angle 6=180

angle 6=180-50

angle 6=130

for value of x

angle 5=86 degree(being corresponding angle)

angle 5=angle 4x-38

86=4x-38

86+38=4x

124/4=x

31=x

relationship between angle 2 and 6 is they are corresponding angles

angle 1=63+61

angle 1=124 degree

3/4m(4m+16n) + m/n open the bracket of equation,

3/4m(4m+16n) + m/n = 3+ 12n/m + m/n

now multiply and devide by mn on RHS,

3/4m(4m+16n) + m/n = (3mn+12n²+m²)/mn

Answer:

187.5 ft²

Step-by-step explanation:

15 x 15 = 225

1/2(5 x 15) = 37.5

225 - 37.5 = 187.5

Answer:

the area is 187.5

Step-by-step explanation:

First we must split this figure into two, now we have a triangle on top of a rectangle (we know this is a rectangle because the length is longer than the width)

to find the area of a rectangle we must use the equation l*w=A so

15*10=150

Now that we have the area of the rectangle we must find the area of the triangle

We can see one side is longer, this shows us that the triangle is 5 units tall and 15 units long

the formula to find the area of a right triangle is ab/2=A

5*15/2=A

75/2=A

37.5=A

now we have both areas we add them together

37.5+150=187.5

187.5 is your answer

Answer:

[tex]31\:\text{square units}[/tex]

Step-by-step explanation:

We can break the composite figure into two triangles and two trapezoids. The area of a triangle is given by [tex]A=\frac{1}{2}bh[/tex] and the area of a trapezoid is given by [tex]A=\frac{b_1+b_2}{2}\cdot h[/tex] (average of the bases multiplied by the height).

Area of first triangle (larger triangle to the figure's left): [tex]\frac{1}{2}\cdot 4\cdot 4=8[/tex]

Area of second triangle (smaller triangle to the figure's right ): [tex]\frac{1}{2}\cdot 2\cdot 5=5[/tex]

Area of first trapezoid (smaller trapezoid directly underneath second triangle and adjacent to both triangles): [tex]4\cdot 2 =8[/tex]

Area of first triangle (larger triangle to the figure's left): [tex]5\cdot 2=10[/tex]

Thus, the area of the entire figure is:

[tex]8+5+8+10=\boxed{31\:\mathrm{units^2}}[/tex]

Selling price = 8600 + Profit

Selling price = 8600 + ( 8600 × 20/100 )

Selling price = 8600 + ( 86 × 20 )

Selling price = 8600 + 1720

Selling price = Rs 10,320

Answer:

33

Step-by-step explanation:

Values beyond the whiskers of the boxplot are called the outliers :

For a right side Outlier :

Values > Q3 ± 1.5(IQR) ;

IQR = Q3 - Q1)

From the data given:

IQR = (40 - 18) = 22

Hence ; the maximum value of right side whisker will be :

1.5(22) = 33

The maximum possible length of the right-side "whisker" is 33

The given parameters are:

Start by calculating the interquartile range (IQR) using:

[tex]IQR = Q3 -Q1[/tex]

So, we have

[tex]IQR = 40 - 18[/tex]

[tex]IQR = 22[/tex]

The maximum possible length of the right side whisker is then calculated as:

[tex]L = 1.5 \times IQR[/tex]

This gives

[tex]L = 1.5 \times 22[/tex]

Multiply 1.5 by 22

[tex]L = 33[/tex]

Hence, the maximum possible length of the right-side "whisker" is 33

Answer:

16 miles

Step-by-step explanation:

A scale drawing is a reduced form in terms of dimensions of an original image / building / object

the scale drawing is usually reduced at a constant dimension

scale of the drawing = original dimensions / dimensions of the scale drawing

Actual area = 3.2 x 5 = 16 miles

[tex]5x + 3y = 25 \\ 5x = 25 - 3y \\ x = \frac{25 - 3y}{5} \\ x = \frac{25}{5} - \frac{3y}{5} \\ x = 5 - \frac{3y}{5} \\ 3x + 4y = 26 \\ 3 (5 - \frac{3y}{5} ) + 4y = 26 \\ 15 + \frac{11y}{5} = 26 \\ \frac{11y}{5} = 26 - 15 \\ \frac{11y}{5} = 11 \\ \frac{5}{11} \times \frac{11y}{5} = 11 \times \frac{5}{11} \\ y = 5 \\ x = 5 - \frac{3y}{5} \\ x = 5 - \frac{3(5)}{5} \\ x = 2[/tex]

Answer:

27.5cm^2

Step-by-step explanation:

you can cut the triangle to make two right triangles

so 11 is the height and the width is 2.5 since your cutting the triangle in half

so 11x2.5=27.5 since its a right triangle you have to divide by two 27.5/2=13.75

that's the answer for one of the triangles now multiply it by two since you need the two right triangle to make the other triangle so the answer is 27.5
