If a student is chosen at random, find the probability that the student studies French given that he or she studies a language. (Can steps be provided too as well pls)

Answer:

s = [tex]\frac{19}{4}[/tex]

Step-by-step explanation:

substitute the given values into the equation

s = (10 × [tex]\frac{1}{2}[/tex] ) + ( [tex]\frac{1}{2}[/tex] × - 2 × ([tex]\frac{1}{2}[/tex] )² )

  = 5 + (- 1 × [tex]\frac{1}{4}[/tex] )

  = 5 - [tex]\frac{1}{4}[/tex]

  = 4 [tex]\frac{3}{4}[/tex]

  = [tex]\frac{19}{4}[/tex]

Answer:

C(50;-20)

Step-by-step explanation:

The question is asking for the midpoint of the line.

The triangle is formed by placing a line directly from the y-axis to the x-axis.

The midpoint theorem is[ (x1+x2)/2 ; (y1+y2)/2 ].

your coordinates at A is (0;-40), because the x value is 0 on the line as shown in the diagram above point A.

Your coordinates for B are (100;0)

C[(x1+x2)/2 ; (y1+y2)/2 ]

C [(0+100)/2 ; (-40+0)/2 ]

C[ 100/2 ; -40/2]

C (50 ; -20)

Answer:

79.94

Step-by-step explanation:

First, let us find the circumference of the wheel (circle).

For that, let us use the below formula.

C = π × d

Given that,

d ⇒ diameter ⇒ 150 cm ⇒ 1.5 m

Let us find now.

C = π d

C = 3.142 × 1.5

C = 4.713

And now to find the number of times that the wheel rotates, you have to divide the total distance that wheel traveled by it's circumference.

Let us find now.

No. of times that wheel rotates = 376.8m ÷ 4.713m

No. of times that wheel rotates = 79.94

Approximately, the wheel will rotates 80 times.

7(x+7)

1. 7(x+7)

2. 2(4m-3)

3. 5(a^2-3)

Answer:

a) 2a

b) -a + b

c) -b -a

Step-by-step explanation:

a) From C, you just go down with a twice.

b) From A, you go up the a hence -a, then you go down b so -a + b.

c) From B, you go down b to O then you go up a to C.

The volume of the ball has a diameter of 15 centimeters around 2 decimal places is 1767.15 cubic centimeters.

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

A sports ball has a diameter of 15 cm.

Then the radius of the ball will be

r = d/2

r = 15/2

r = 7.5 cm

Then the volume of the ball will be

[tex]\rm Volume = \dfrac{4}{3} \times \pi \times r^3\\\\Volume = \dfrac{4}{3} \times \pi \times 7.5^3\\\\Volume = \dfrac{4}{3} \times \pi \times 421.875\\\\Volume = 1767.15\ cm^3[/tex]

Answer:

625 cm^2

Step-by-step explanation:

Break it into a rectangle on the bottom and a triangle on top

rectangle area = 50 x 8 = 400 cm^2

triangle area = 1/2 b * h = 1/2 * 50 * 9 = 225 cm^2

added together = 625 cm^2

Answer:

D

Step-by-step explanation:

The problem is put in different fractions to make it more confusing.

1 1/15 miles+ 1 3/5 miles+ 1 2/3 miles

We can find the common denominator of all of the fractions.

[tex]1 \frac{1}{15} + 1 \frac{9}{15} + 1 \frac{10}{15} \\= 3+\frac{20}{15} =4 \frac{5}{15}\\\\=[/tex]4  1/3

[tex]monday = 1 \frac{1}{15} [/tex]

[tex]tuesday = 1 \frac{3}{5} [/tex]

[tex]wednesday = 1 \frac{2}{3} [/tex]

the total number of miles Kenya ran in 3 days.

[tex] \frac{16}{15} + \frac{8}{5} + \frac{5}{3} [/tex]

[tex] = \frac{16}{15} + \frac{8 \times 3}{5 \times 3} + \frac{5 \times 5}{3 \times 5} [/tex]

[tex] = \frac{16 + 24 + 25}{15} [/tex]

[tex] = \frac{65}{15} = \frac{13}{3} [/tex]

[tex] = 4 \frac{1}{3} [/tex]

therefore, the correct answer is option D.

Answer:

the last answer is correct, lim as it aproaches 33- is -6, and as it aproaches 33+ is -15

Step-by-step explanation:

The limit as the function approaches 33+ means the limit as the function approaches 33 from the right side, and the table shows it approaches 15 from x is above 33.

When x is slightly below 33, it aproaches -6.

The values of lim g (x) when x → - 33 and lim g(x) when x → 33 are,

⇒ - 6 and 15

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

We have to given that;

Table shown the relation between x and g (x).

Now, By table we get;

At x = 32.999;

g (x) = - 6.01

At x = 33.001;

g (x) = - 15.01

Thus, The values of lim g (x) when x → - 33 and lim g(x) when x → 33 are,

⇒ - 6 and 15
