Since more than 4 vans will be required in total, at least 4 vans should be reserved.

In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to one another. In mathematics, inequalities specify the relationship between two non-equal values. Equal does not imply inequality. The "not equal symbol ()" is typically used to indicate that two values are not equal. The expression 5x 4 > 2x + 3 resembles an equation, but the equals sign has been replaced by an arrowhead. It is an illustration of inequality. This shows that the left part, 5x 4, is bigger than the right part, 2x + 3.

Here,

Since the total number of people is at least 28, then the total number of people must be 28 or more, so

7v≥28

v≥4

The total number of vans needed will be more than 4 that is at least 4 vans should be booked.

The value of y coordinate of the unit circle is given by [tex]\sqrt{7}/4[/tex]

Given that,

x - coordinate of p =-3/4 . Let the co-ordinate of point P = (-3/4 , y).

To find : The y coordinate in Quadrant IV

By using the formula for unit circle,

Unit circle means a circle whose radius is one or 1

x²+ y² = 1

y²+ (-3/4)² = 1

y²+ (9/16) = 1

y² = 1 -9/16

y² = 7/16

y= [tex]\sqrt{7/16}[/tex]

y =  ± [tex]\sqrt{7}/4[/tex]

It is given that point P is in quadrant IV so in IV quadrant y is positive.

Therefore, y =  [tex]\sqrt{7}/4[/tex]

689 minutes long If Casey's monthly bill was $38.44, she would talk on her cell phone.

Given;

A cell phone provider charges a set monthly fee of $3. 99 plus an extra $0.05 per minute.

If Casey's monthly phone bill was $38.44, how many minutes did she use? 

The total charges of the flat rate per month = $3.99

The total additional charge per minute = $0.05

Total monthly bill = $38.44

Total additional charge = Total monthly bill - Total charge of flat rate

                                       = $38.44 - $3.99

                                       = $34.45

Total time per minute Casey can talk = Total additional charge/Total additional charge per minute

                                                       = $34.45 / $0.05

Error = (10-9)°C & Error percentage = 10%.

Given that temperature today in Chicago is 50°F

Standard conversion formula

°C = [tex]\frac{5}{9} *(T^{0}F-32)[/tex]   - 1

Given T = 50°F

Put the value in equation 1

[tex]^{0}C = \frac{5}{9} *(50-32) \\\\= \frac{5}{9}*18\\ \\= \frac{90}{9}[/tex]

= 10°C

Tommasa's grandmothers rule is to subtract 32 from the value in °F and multiply the result by 0.5

i.e. [tex]^{0}C = 0.5(T^{0} F-32)[/tex]   - 2

Given temperature is T = 50°F

Put the value of T in equation 2

[tex]^{0}C = 0.5*(50-32)[/tex]

= 0.5 * 18

= 1/2 * 18

= 9°C

Temperature obtained by standard conversion Formula is 10°C and the temperature obtained by Tammaso's grandmother rule is 9°C.

So error = (10-9)°C

= 1°C

Error percentage = [tex]\frac{1}{10}*100[/tex]

The value of sin θ of the given right angle triangle using trigonometric ratios is; A: 5/13

The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec). They are based on the angles formed from the ratio of sides of a right angle triangle. Thus;

sin θ = opposite/hypotenuse

cos θ = adjacent/hypotenuse

tan θ = opposite/adjacent

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

From the given image, we see that;

Hypotenuse = 13

We need to check if 8.1^4 x 8.1^8 be equal to 8.1^12 and if 8.1^12 be equal to 8.1^6.

We will use laws of exponents to solve the given expression:

8.1^4 x 8.1^8 = 8.1^(4 + 8) = 8.1^12

So, 8.1^4 x 8.1^8 = 8.1^12

Also,

8.1^12 = 8.1^(2 * 6) = (8.1^2)^6

So, 8.1^12 ≠ 8.1^6.

By applying the exterior angle property, the measure of the exterior angle to ∠G in triangle EFG is 120.7°

In Mathematics, the exterior angle property can be defined as a theorem which states that the measure of an exterior angle in a triangle is equal in magnitude to the sum of the measures of the two remote or opposite interior angles of that triangle.

To determine the value of ∠G in triangle EFG (ΔEFG), we would have to apply exterior angle property.

Then, the exterior angle property can be used to model triangle EFG (ΔEFG)  is given by:

∠G = m∠E +m∠F

Now Substituting the given parameters into the formula, we have

∠G = 84.3° + 36.4°.

The set of probabilities for the number of eaglets is the

probabilities for how many eaglets will survive.

The table that shows the probability distribution is the option C;

X      0         1         2

p(x)   0.35   0.60   0.05

  P(O) = 0.5 is the likelihood that the elder eaglet will live.

  Therefore;

   P(O') = 1 - 0.5 = 0.5 is the probability that the older eaglet won't survive.

  The likelihood that the younger eaglet will survive if the older eaglet              does not P(Y|O) = 10%

Therefore;

The likelihood that the elder eaglet will live while the younger eaglet does not survive is P(Y'|O) = 1 - 10% = 90%.

When the older eaglet does not survive, the younger eaglet has a 30% survival chance (P(Y|O')).

Therefore;

The likelihood that the younger eaglet will not survive, compared to the elder eaglet, is P(Y'|O') = 1 - 30% = 70%

The collection of potential probabilities for the number of eaglets that survive is expressed as the probability distribution, or P(X)

The range of potential results includes:

Never survives:

The likelihood that no eaglets survive is equal to P(O') × P(Y'|O') = 0.5 × 0.7 = 0.35.

The only survivor is:

The likelihood that only one eaglet survives is determined by P(O) = P(Y'|O) × P(O') = P(Y|O'), which results in P = 0.5 × 0.9 + 0.5 × 0.3 = 0.6 Both survive:

The odds of both eaglets surviving are P(O) ×P(Y|O) = 0.5 × 0.1 = 0.05.

What is the intermediate value theorem?

Intermediate value theorem is theorem about all possible y-value in between two known y-value.

x-intercepts

-x^2 + x + 2 = 0

x^2 - x - 2 = 0

x = -1, x = 2

y intercepts

f(0) = -x^2 + x + 2

f(0) = -0^2 + 0 + 2

The transformation f(x)—>f(1/3x) due to the graph of f(x), will be dilation horizontally and vertically.

What is Transformation of Function?

Transformation of functions refers to the graph's curve moving to the left, right, up, or down, expanding, contracting, or reflecting. Just dilation, out of these three transformations, alters the size of the original shape; the other two only adjust the position.

A translation happens when each point on a graph (which represents a function) travels in the same direction and by the same amount. There are two kinds of function translations.

Stretching or compressing is a dilation. The x-values on a graph are all scaled up by the same amount when a dilation that is parallel to the x-axis occurs. The y-values are all increased by the same scale factor if it is dilated parallel to the y-axis.

f(x) to become f(1/3x), Then it will go dilation "vertically and horizontally".
