As there are three zero in expression

Answer:

V ≈ 68.63 cm³

Step-by-step explanation:

the volume (V) of a sphere is calculated as

V = [tex]\frac{4}{3}[/tex]πr³

the volume of a hemisphere is half the volume of a sphere, so

V = [tex]\frac{1}{2}[/tex] × [tex]\frac{4}{3}[/tex] πr³ = [tex]\frac{2}{3}[/tex] πr³ , then

V = [tex]\frac{2}{3}[/tex] π × 3.2³

  = [tex]\frac{2}{3}[/tex] π × 32.768

  ≈ 68.63 cm³ ( to 2 dec. places )

Using the binomial distribution, we have that:

a) The distribution is given by:

b) 0.3125 = 31.25%.

The formula is:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

In this problem, we have that:

The distribution is given by the probability of each outcome, hence:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 0) = C_{4,0}.(0.5)^{0}.(0.5)^{4} = 0.0625[/tex]

[tex]P(X = 1) = C_{4,1}.(0.5)^{1}.(0.5)^{3} = 0.25[/tex]

[tex]P(X = 2) = C_{4,2}.(0.5)^{2}.(0.5)^{2} = 0.375[/tex]

[tex]P(X = 3) = C_{4,3}.(0.5)^{3}.(0.5)^{1} = 0.25[/tex]

[tex]P(X = 4) = C_{4,4}.(0.5)^{4}.(0.5)^{0} = 0.0625[/tex]

The probability of at least 3 daughters is given by:

[tex]P(X \geq 3) = P(X = 3) + P(X = 4) = 0.25 + 0.0625 = 0.3125[/tex].

To translate something:

  ⇒ is to write out the equations

Let's examine what information this problem gives us:

            ⇒ with '2' being the number of adults tickets

                ⇒total charge from purchasing adult tickets = 2 * 62.5 = 125

            ⇒ with 'x' being the number of child tickets bought

                 ⇒total charge from purchasing child tickets = 42.5x

Since the sum of total charge from purchasing adult tickets and total charge from purchasing child tickets is equal to 400:

   ⇒ 42.5x + 125 = 400 <== translated form

Let's solve:

   [tex]42.5x+125=400\\42.5x=275\\x=6.47[/tex]

If the measure of the angle ∠RQT is 125°. Then the measure of the angles ∠RQS and ∠SQT will be 44° and 81°.

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

If the measure of the angle ∠RQT is 125°. Then the measure of the angles ∠RQS and ∠SQT will be

Then we have

      ∠RQS + ∠SQT = 125°

(3x - 10)° + (4x + 9)° = 125°

                      7x - 1 = 125°

                          7x = 126°

                            x = 18°

Then the measure of the angle ∠RQS will be

∠RQS = 3 × 18 - 10

∠RQS = 44°

Then the measure of the angle ∠SQT will be

∠SQT = 4 × 18 + 9

∠SQT = 81°

Step-by-step explanation:

Taking the cosine ratio of the angle of depression :

The regression line is y = 10x + 125, and the value of calories is 135, and when x = 12 the value of y = 245 from the regression line, butbut the actual value is 225.

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dot's relationship.

Here the scatter plot is not given, but we can draw the scatter plot using the data which is given with two variables such as (x, y) and the line which is best fit of the given data.

From the data given, we can write the line of best fit in slope and y-intercept form:

y = mx + b

Plug m = 10 and b = 125

y = 10x + 125

The number of fat grams in an item having that number of fat calories.

As we have the regression line:

y = 10x + 125

Put x = 1 in the regression line:

y = 10(1) + 125

y = 135 calories

For x = 12

y = 10(12)+125 = 245

But the actual value from the graph is 225.

Thus, the regression line is y = 10x + 125, and the value of calories is 135, and when x = 12 the value of y = 245 from the regression line, but but the actual value is 225.

Step-by-step explanation:

He makes a profit in total of $8381

The store makes a profit of $29 per sweater.

Here, we have to calculate the profit per sweater, we need to find the difference between the selling price and the cost price (purchase price) of each sweater.

Given:

Number of sweaters bought = 17

Cost of buying 17 sweaters = $68

Selling price of 17 sweaters = $561

Profit per sweater = Selling price per sweater - Cost price per sweater

First, calculate the cost price per sweater:

Cost price per sweater = Total cost / Number of sweaters

Cost price per sweater = $68 / 17

Cost price per sweater = $4.

Now, calculate the profit per sweater:

Profit per sweater = Selling price per sweater - Cost price per sweater

Profit per sweater = $561 / 17 - $4

Profit per sweater = $33 - $4

Profit per sweater = $29.

The store makes a profit of $29 per sweater.

The angle bisector of any angle in a triangle will divide the side opposite the bisected angle in the ratio of the sides containing the angle.

Therefore:

AD : DC = BA : BC

Given:

Substituting the given values into the ratio and solving for x:

[tex]\implies \sf x : 11 = 18 : 19[/tex]

Answer:

[tex]\displaystyle x = 0 \text{ and } x = 1[/tex]

Step-by-step explanation:

We are given and asked to solve the equation:

[tex]\displaystyle \frac{x}{x-2} + \frac{x-1}{x+1} = -1[/tex]

We can first remove the rational expressions by multiplying both sides of the equation by its LCM (in this case, by (x - 2)(x + 1)):

[tex]\displaystyle (x-2)(x+1) \left( \displaystyle \frac{x}{x-2} + \frac{x-1}{x+1}\right) = -1(x-2)(x+1)[/tex]

Simplify:

[tex]\displaystyle x(x+1)+(x-1)(x-2) = -(x-2)(x+1)[/tex]

Expand and isolate:

[tex]\displaystyle \begin{aligned} (x^2 + x) + (x^2 - 3x + 2) & = -(x^2 -x -2) \\ \\ 2x^2 - 2x + 2& = -x^2 + x + 2 \\ \\ 3x^2 - 3x & = 0 \end{aligned}[/tex]

Hence solve for x:

[tex]\displaystyle \begin{aligned} 3x(x - 1) & = 0 \\ \\ x & = 0\text{ or } x = 1\end{aligned}[/tex]

In conclusion, the solutions of the equation are x = 0 and x = 1.

Step-by-step explanation:

the area of a whole circle (360°) is

pi×r²

in our case

pi×10² = 100pi

but here we don't need the full circle. we only need a fraction of the whole circle : 128/360

so, the area of the sector is

100pi × 128/360 = 100pi × 16/45 = 20pi × 16/9 =

= 111.7010721... cm² ≈ 111.7 cm²

Answer:

ED = 6.5 cm

BE = 14.4 cm

Step-by-step explanation

AB/BC = AE/ED is less than or eqauls ED = BC×AE/AB

so

ED = 5×26/20 = 130/20 = 6.5 cm

and

AB/AC = BE/CD => BE = AB×CD/AC

so

BE = 20×18/25 = 360/25 = 14.4 cm

(x_1+x_2)=-b/a=18/3=6

x_1x_2=c/a=-21/3=-7

So

x_1-x_2=8

Answer:

[tex]x{_1}^2+x{_2}^2=50[/tex]

[tex]|x_1-x_2|=8[/tex]

Step-by-step explanation:

Given equation:

[tex]3x^2-18x-21=0[/tex]

Factor to find the roots:

[tex]\implies 3(x^2-6x-7)=0[/tex]

[tex]\implies x^2-6x-7=0[/tex]

[tex]\implies x^2+x-7x-7=0[/tex]

[tex]\implies x(x+1)-7(x+1)=0[/tex]

[tex]\implies (x-7)(x+1)=0[/tex]

Therefore:

[tex]\implies (x-7)=0 \implies x=7[/tex]

[tex]\implies (x+1)=0 \implies x=-1[/tex]

Therefore, the roots of the quadratic equation are:

[tex]x = 7,\quad x = -1[/tex]

Let  [tex]x_1 = 7[/tex]

Let  [tex]x_2 = -1[/tex]

[tex]\implies x{_1}^2+x{_2}^2=7^2+(-1)^2=50[/tex]

[tex]\implies |x_1-x_2|=|7-(-1)|=8[/tex]

Answer:

Answer:

False

Step-by-step explanation:

False. Both surface area cannot be find using the same formula.

The area of a three dimensional object on it's outer surface is called the surface area of the object.

Right cone is a cone where the axis of the cone is perpendicular to the base .

Whereas, oblique cone has the axis of cone not perpendicular to the base.

Base area would be same for both right and oblique cones.

But the lateral surface area will be different.

Hence the surface area will be different.

Hence the surface area formula for a right cone is not same to find the surface area of an oblique cone.
