Step-by-step explanation:

Maya have $212.50 money in her savings to begin with, and she have left $127.50 in her savings after buying the bicycle.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

We have to given that;

Maya spent 40% of her savings to pay for a bicycle that cost her $85.

Now, Let the amount of money in her savings to begin with = x

So, We can formulate;

⇒ 40% of x = $85

Solve for x;

⇒ 40/100 × x = $85

⇒ 2/5x = $85

⇒ 2x = $85 × 5

⇒ 2x = $425

⇒ x = $425/2

⇒ x = $212.50

Thus, She have left in her savings after buying the bicycle is,

⇒ $212.50 - $85

The standard normal distribution (z distribution) is a normal distribution with a mean of 0 and a standard deviation of 1. Any point (x) from a normal distribution can be converted to the standard normal distribution (z) with the formula z = (x-mean) / standard deviation.

In information, the standard deviation is a degree of the quantity of variation or dispersion of a fixed of values. A low standard deviation indicates that the values tend to be near the implied (additionally called the predicted price) of the set, whilst an excessive preferred deviation suggests that the values are spread out over a wider variety.

Popular deviation can be abbreviated SD, and is maximum commonly represented in mathematical texts and equations by means of the decrease case Greek letter σ (sigma), for the population standard deviation, or the Latin letter s, for the sample general deviation.

An angle is 270 degrees when it is a reflex angle .

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles.

An angle that is greater than 180 degrees and less than 360 degrees is referred to as a reflex angle. Reflex angles include, for instance, 270 degrees. There are several sorts of angles in geometry, including acute, obtuse, and right angles—angles that are less than 180 degrees.

A reflex angle equals the summation of 180 degrees and any of the primary angles (acute, right and obtuse angles). Therefore,

Answer:

More fish were caught per person on Day 2

Step-by-step explanation:

Day 1:

3 people caught 1 fish = 3 fish

6 people caught 2 fish = 12

6 caught 3 = 18

6 caught 4 = 24

6 caught 5 = 30

3 caught 6 = 18

Total fish caught =  105

That's 105/30 = 3.5 fish per person

Day 2:

3 people caught 1 fish = 3 fish

3 caught 2 = 6

4 caught 3 = 12

6 caught 4 = 24

7 caught 5 = 35

7 caught 6 = 42

Total fish caught = 122

One of the most important considerations when designing or evaluating a function is its convexity. A function is said to be convex if it is possible to represent its shape in a single, continuous surface.

However, it is not always straightforward to determine if a particular function is convex or not. There are various criteria that can be used to determine whether a given function is convex or nonconvex. These include the "vertex test" and the "region test." The vertex test is a simple and intuitive way to determine whether or not a function is convex. It can be performed as follows: First, identify any critical points of the function using the first derivative. Then, draw a graph of these functions and identify the point at which the graphs of these functions intersect. The point where this intersection occurs is the vertex of the function. If the graph of the function does not intersect at any point, then it cannot be concave and can therefore be considered to be convex.

Answer:

Common ratio = 2, Third term = 12

Step-by-step explanation:

ar⁴ = 48........ equation 1

ar = 6.......... equation 2

divide equation 1 by equation 2

r³ = 8

r = ³√8

r = 2

To get the third term we must first get the first term

Since ar = 6 and r = 2, then 2a = 6 and a = 3

3rd term = ar²

3 × 2² = 3 × 4 = 12

Answer:

r = 2 and a₃ = 12

Step-by-step explanation:

the nth term of a GP is

[tex]a_{n}[/tex] = a₁ [tex]r^{n-1}[/tex]

where a₁ is the first term and r the common ratio

given a₂ = 6 and a₅ = 48 , then

a₁r = 6 → (1)

a₁[tex]r^{4}[/tex] = 48 → (2)

divide both sides of (2) by (1) to eliminate a₁

[tex]\frac{a_{1}r^{4} }{a_{1}r }[/tex] = [tex]\frac{48}{6}[/tex] ( cancel r and [tex]r^{4}[/tex] by r )

r³ = 8 ( take cube root of both sides )

r = [tex]\sqrt[3]{8}[/tex] = 2

substitute r = 2 into (1) and solve for a₁

a₁ × 2 = 6 ( divide both sides by 2 )

a₁ = 3

a₂ = a₁ × r = 3 × 2 = 6

a₃ = a₂ × 3 = 12

Kate will have to pay $56.25 out of pocket for her doctor visit.

The formula for calculating coinsurance is Coinsurance = (Cost of Service x Coinsurance Percent) / 100.If Kate has not met her deductible yet, she will need to pay the full $25 deductible plus 25% of the remaining bill.

The formula for calculating the amount Kate needs to pay is as follows:

Cost to Patient (C) = Deductible (D) + Coinsurance (C) * (Bill – Deductible)  In this case, Kate would need to pay (125 x 25) / 100 = $31.25. The extra $25 is the deductible, which is the amount she must pay before her insurance kicks in.This amount is due immediately upon the visit, regardless of whether or not she has met her deductible So in total, Kate would have to pay $25 + $31.25 = $56.25.

The change in temperature between noon and 3:30 p.m. is 75 - 70 = 5 degrees F.

The number of hours between noon and 3:30 p.m. is 3.5 hours.
