Two quantities, Pand Q, are connected by
the relationship P= kQ+ c, where k and c
are constants. Q= 60 when P= 10 and
Q= 240 when P= 100.
Find the equation connecting P and Q.

Answers

Answer 1

Answer:

P = 0.5Q - 20

Step-by-step explanation:

P = kQ + c

substitute Q = 60 , P = 10 into the equation

10 = 60k + c → (1)

substitute Q = 240, P = 100 into the equation

100 = 240k + c → (2)

subtract (1) from (2) term by term to eliminate c

90 = 180k ( divide both sides by 180 )

[tex]\frac{90}{180}[/tex] = [tex]\frac{1}{2}[/tex] = 0.5 = k

substitute k = 0.5 into (1) and solve for c

10 = 60(0.5) + c

10 = 30 + c ( subtract 30 from both sides )

- 20 = c

then

P = 0.5Q - 20

The probability when x is greater than 120 is 0.0367. Then the correct option is D.

What is a normal distribution?

The Gaussian Distribution is another name for it. The most significant continuous probability distribution is this one. Because the curve resembles a bell, it is also known as a bell curve.

The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.

The mean is 95 and the standard deviation is 14. Then the probability when x > 120 will be

The z-score will be

z = (120 - 95)/ 14

z = 1.7857

Then the probability will be

P(x > 120) = P(z > 1.7857)

P(x > 120) = 1 - P(x<120)

P(x > 120) = 1 - 0.96293

P(x > 120) = 0.0367

GIVING BRAINLIEST AND MAX POINTS! ANSWER ASAPPP! The initial velocity of a projectile is 217 ft/sec, and the firing angle is 12°. Calculate the horizontal distance.

a
599 feet
b
699 feet
c
499 feet
d
799 feet

Answers

Answer:

a)  599 feet

Step-by-step explanation:

** As the measure of distance is in feet, we must use the value of gravity in ft/s² **

Constant Acceleration Equations (in ft)

s = displacement in ftu = initial velocity in ft/sv = final velocity in ft/sa = acceleration in ft/s²t = time in s (seconds)

Assuming that the projectile is fired at an angle of 12° above the horizontal.

Consider the vertical and horizontal motion separately.

Vertical motion

First, find time by resolving vertically, taking up as positive and
g = 32 ft/s²

s = 0u = 217 sin 12°v = a = -32t = t

[tex]\begin{aligned}\textsf{Using}\quad s & =ut+\dfrac{1}{2}at^2\\\implies 0 & = 217 \sin 12^{\circ}t+\dfrac{1}{2}(-32)t^2\\0 & = 217 \sin 12^{\circ}t-16t^2\\t(16t-217 \sin 12^{\circ}) & = 0\\16t & = 217 \sin 12^{\circ}\\t & = \dfrac{217 \sin 12^{\circ}}{16}\\t & = 2.819802307...\: \sf s\end{aligned}[/tex]

Horizontal motion

Resolving horizontally, taking right as positive:

(The horizontal component of velocity is constant, as there is no acceleration horizontally)

s = su = 217 cos 12°v = 217 cos 12°a = 0t = 2.819802307...

[tex]\begin{aligned}\textsf{Using}\quad s & =ut+\dfrac{1}{2}at^2\\\implies s & = (217 \cos 12^{\circ})(2.819802307...)+\dfrac{1}{2}(0)t^2\\& =598.5256808...\end{aligned}[/tex]

Therefore, the horizontal distance is 599 ft (nearest foot)

Answers

Probability that the next person will purchase more than one costume as a fraction in simplest form is; 11/113

How to find probability?

We are given the data for number of people who visited the website and the number of costumes purchased in a single day as;

Number of visitors that purchased no costume = 27 visitors

Number of visitors that purchased exactly one costume = 75

Number of visitors that purchased more than one costume = 11

Total number of visitors = 27 + 75 + 11 = 113

Thus;

Probability that the next person will purchase more than one costume as a fraction in simplest form is;

P(purchase more than one costume) = 11/113

(h,k) is the vertex

A square has a perimeter of 40 feet. Find the length of the
diagonal of the square.

Answers

Answer:

14.14

Step-by-step explanation:

Answer:

The length of the diagonal of the square is about 14.142 feet

Step-by-step explanation:

Step 1:  Determine the length

[tex]P = 4(l)[/tex]

[tex]40\ ft = 4(l)[/tex]

[tex]\frac{40\ ft}{4}=\frac{4(l)}{4}[/tex]

[tex]10\ ft = l[/tex]

Step 2:  Determine the diagonal length

Pythagorean theorem → [tex]a^2 + b^2 = c^2[/tex]

a and b are going to be the sides of the square which are both 10 ft so we just plug those in and solve for c

[tex](10)^2 +(10)^2 =c^2[/tex]

[tex]100+100=c^2[/tex]

[tex]\sqrt{200}=\sqrt{c^2}[/tex]

[tex]14.142=c[/tex]

Answer:

369.5 ft²

Step-by-step explanation:

Separate the figure into 2 rectangles and 2 triangles.

(see attached image)

Area 1

Area of a rectangle = width × length

                                 = 4 × 5

                                 = 20 ft²

Area 2

Area of a rectangle = width × length

                                 = 8 × (4 + 4 + 5)

                                 = 8 × 13

                                 = 104 ft²

Area 3

Area of a triangle = 1/2 × base × height

                             = 1/2 × (6 + 4 + 5 + 4 - 6) × 23

                             = 1/2 × 13 × 23

                             = 149.5 ft²

Area 4

Area of a triangle = 1/2 × base × height

                             = 1/2 × 8 × (21 + 8 - 5)

                             = 1/2 × 8 × 24

                             = 96 ft²

Total Area

Area 1 + Area 2 + Area 3 + Area 2 = 20 + 104 + 149.5 + 96

                                                        = 369.5 ft²

Answer:

  x = -47.1

Step-by-step explanation:

Each of the absolute value functions causes the overall behavior of the equation to change where that absolute value function's argument is zero. Those values of x are -7, -5/2, -2/5.

These breakpoints cause the domain of the equation to be divided into 4 parts. A graphing calculator shows us that solutions exist only in the two regions ...

x < -7-7 ≤ x < -5/2

In those regions, the equation simplifies to ...

x < -7

  2(-(x +2/5)) -2(-(x +7)) = 2/3x +(-(x +5/2))

  x(-2 +2) -4/5 +14 = x(2/3 -1) -5/2 . . . . collect terms

  15.7 = -1/3x . . . . . . add 5/2

  x = -47.1 . . . . . . . multiply by -3

__

-7 ≤ x < -5/2

  2(-(x +2/5)) -2(x +7) = 2/3x +(-(x +5/2))

  x(-2 -2) -4/5 -14 = x(2/3 -1) -5/2 . . . . collect terms

  (-3 2/3)x = 12.3 . . . . . . . . add 1/3x +14.8

  x = -36.9/11 = -369/110

  x = -3 39/110 ≈ -3.35454... (2-digit repeat)
