As a result:

10% of people identify as left-handed.

P(left-handed) = 0.1 is the probability of success.

Selection number (n) equals six

The number of left hands in the selection (x) is precisely 2 P(6, 2) = 6C2 * 0.1 * (1 - 0.1) (6-2)

P(6, 2) = 15 * 0.01 * 0.6561\P(6, 2)

The area of the circle-shaped rug is 379.94 square inches

The formula for calculating the area of a circle is expressed as;

Area = πr^2

Where;

From the information given, we have the value of the circumference as 69.08 inches

We need to find the value of the radius.

The formula for calculating the circumference of a circle is mathematically expressed as;

Circumference = 2πr

Where: r is the radius of the circle and π takes the value 3. 14

Now, substitute the value into the formula for circumference of a circle, we have;

69.08= 2(3.14)r

Divide both sides by the coefficient of r

r = 69.08/6. 28

r = 11 inches

Then, area = 3.14 × (11)^2

Area = 3.14 × 121

Area = 379.94 square inches

Hence, the value is 379.94 square inches

(a) The fraction for the given percentage is 3% = 3/100 and its decimal number is 0.03.

(b) The fraction for the given percentage is 15% = 15/100 = 3/20 and its decimal number is 0.15.

Here the fractions 15/100 and 3/20 are equivalents.

Two fractions whose numerators and denominators are different but whose value is the same are said to be equivalent fractions.

For example, a/b = k and c/d = k. Then a/b = c/d.

The fractions a/b and c/d are equivalent fractions.

Given percentages are 3% and 15%.

A percentage is a ratio of the parts in the whole of 100 parts.

So, 3% = 3/100

This is nothing but a fraction.

To convert it into decimals, divide the numerator by the denominator. So, we get 3/100 = 0.03.

Similarly, for 15%, the fraction is 15/100

This fraction when divided by 5 in both numerator and denomiantor, we get (15/5)/(100/5) = 3/20

So, the fraction 3/20 is the equivalent fraction for the fraction 15/100 Since their values are the same i.e., 0.15. Thus, the decimal number for those fractions is 0.15.

The GPA of the girls is 3.12

In this question, we have been given a class has 12 boys and 18 girls.

The class as a whole has a GPA (grade point average) of 2.88, and the boys have a GPA of 2.52

We need to find the GPA of girls.

Let m be the GPA of girls.

The weighted average GPA would be,

(12(2.52) + 18m)/ (12+18) = 2.88

We solve above equation to find the value of m

30.24 + 18m = 30 * 2.88

18m = 86.4 - 30.24

18m = 56.16

m = 3.12

Therefore, the GPA of the girls in the class is 3.12

Answer: A. No, because two points with the same x-value have different y values.

Step-by-step explanation: A function is a relation in which each element in the domain (the set of x-values) is paired with exactly one element in the range (the set of y-values). If there are two points with the same x-value but different y-values, then there is more than one y-value for a given x-value, which violates the definition of a function. Therefore, the given relation is not a function.

What is the definition of a velocity simple?

The direction of the movement of the body or the object is defined by its velocity. In its basic form, speed is a scalar quantity.

                        In essence, velocity is a vector quantity. It measures how quickly a distance changes. It is the displacement change rate.

vo = 48     v(t) = integral of a(t) plus vo, the initial velocity

a(t) = -2

v(t) = -2t + 48 = 0 when t= 21 seconds, the time to stop

s(t) = -t^2 +48t  

s(21) = -(21)^2 + 48(21) = 1008-441 = 567 feet

The equation of the line is y = -2x + c

What is an equation ?

The definition of an equation in algebra is a mathematical statement that proves two mathematical expressions are equal. Consider the equation 3x + 5 = 14, where 3x + 5 and 14 are two expressions that are separated by the symbol "equal."

The three main types of linear equations are the slope-intercept form, standard form, and point-slope form.

Equations are logical assertions in mathematics that have two algebraic expressions on either side of an equals (=) sign. The expression on the left and the expression on the right are shown to be equal in reference to one another.

To find the slope, use the two points (4.5,0) and (0,9) and substitute these in the slope formula:

m = [tex]\frac{(y_{2} - y_{1})}{(x_{2} - x_{1} )}[/tex]

What is an linear equation?

Equations with the highest degree of 1 are called linear equations. This means that the exponent of the variable in the linear equation is greater than 1. The graph of a linear equation is always a straight line.

There is a linear equation in one variable and a linear equation in two variables.

It is given that there are two types of alien live on the planet Starlight Zoomas and Popsies.

Zoomas have 3 eyes and 2 legs

Popsies have 4 eyes and 5 legs

There are total 38 eyes and 37 legs

Let there are x number of Zoomas and y number of Popsies.

According to question:

3x + 4y = 38 ..........(1)

2x + 5y = 37 ...............(2)

Solve the above system of equation.

Find the value of x from the equation(1)

3x + 4y = 38

3x = 38 - 4y

x = [tex]\frac{38-4y}{3}[/tex]

Substitute this value of x in equation(2)

2( [tex]\frac{38-4y}{3}[/tex]) + 5y = 37

⇒ [tex]\frac{76-8y}{3}+5y = 37[/tex]

⇒ [tex]\frac{76-8y+15y}{3}=37[/tex]

⇒ 76 + 7y = 111

⇒ 7y = 111 - 76

⇒ 7y = 35

⇒ y = 35/7 = 5

Substitute this value of y in the value of x

x = [tex]\frac{38-4y}{3}[/tex]

x = [tex]\frac{38-4(5)}{3}=\frac{38-20}{3}=\frac{18}{3}=6[/tex]

Answer:

x (in simple terms)< -11/7 or -1 4/7

Step-by-step explanation:

1) Place x on one side: The point of this is to islolate x (and to keep things simple make x a positive variable if you can). One way of doing this is adding 8x on both sides what we now get is 14 < 14x + 36

2) Subtract 36 on both sides: We doing this for the same reason as the 1st step which is to islolate x so after this the new equation is -22 < 14x

3) Divide 14 on both sides: Since we aren't dividing by a negative number the sign remains the same the answer is -22/14 < x or x> -22/14 but to simply find the greatest common factor for both the numberator and demonationr which is 2 and divide from there the answer is x> -11/7 or x> -1 4/7

Answer:

b = 72

Step-by-step explanation:

Since AB and AC are congruent then Δ ABC is isosceles with base angles also congruent, that is

∠ ACB = ∠ ABC = b

b + b + 36 = 180

2b + 36 = 180 ( subtract 36 from both sides )

2b = 144 ( divide both sides by 2 )

If the correlation between variables a and b is +0.52, then it shows that as value on A increases, the value on B increases

The correlation between variable a and variable b = +0.52

The correlation is defined as the statistical variable that show the relationship between the variables. So when one variable increases another variable increase or if one variable decreases another variable decreases. So correlation show the the variable changes at constant rate.

In the given details

The correlation between variable a and variable b is +0.52. The sign of the correlation is positive so variable a is increasing and the variable b will also increases at constant rate

The points used for the slope is gotten from the graph as (2,-1) and (8,4)

m = (y₂ - y₁) / (x₂ - x₁)

The coordinates of the point P that is 2/5 of the way from A to B are:

P = (-5.6, 11,2)

If we want to find a point that is 2/5 of the way between two points (x₁, y₁) and (x₂, y₂), then we need to use the formula:

( (3/5)x₁ + (2/5)x₂,  (3/5)y₁ + (2/5)y₂)

Here the two points are (-8, -2) and (6, 19), using the above formula we will get the point P:

The rate of change of base is 5 cm/min.

The rate of change function is defined as the rate at which one quantity is changing with respect to another quantity. In simple terms, in the rate of change, the amount of change in one item is divided by the corresponding amount of change in another. The rate of change formula gives the relationship describing how one quantity changes in relation to the change in another quantity.

Let us assume that

h = height of the triangle

[tex]\frac{dh}{dt}[/tex] = rate of increase of height = 1 cm/min

A = Area of triangle

[tex]\frac{dA}{dt}[/tex] = rate of increase of area = 13 cm²/min

Area of traingle, A = 1/2*(b*h)

When A = 12 cm² and h = 4 cm,

Put in above formula,

12 = 1/2 * (b)(4)

∴ b = 6 cm

A = 1/2 * b*h

[tex]\frac{dA}{dT} = \frac{1}{2}h\frac{db}{dt} + \frac{1}{2}b\frac{dh}{dt} \\\\13 = \frac{1}{2}*4* \frac{db}{dt} + \frac{1}{2}*6*1\\\frac{db}{dt} = 5 cm/min[/tex]
