Orange colors - Why are the locations of the police station and fire department congruent?

blue colors - Why are the locations of the restaurant and bank congruent?​

Answer:

0.2356

Step-by-step explanation:

Given that:

μ = 40; σ = 16

P(50 ≤ x ≤ 70) :

Using the Zscore formula :

(x - μ) / σ

P((50 - 40) / 16 ≤ Z ≤ (70 - 40) / 16)

P(50 ≤ x ≤ 70) = P(0.625 ≤ Z ≤ 1.875)

Using the Z probability calculator :

P(Z ≤ 1.875) - P(Z ≤ 0.625) -

0.9696 - 0.73401

= 0.23559

= 0.2356

Answer:

its b

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

We are given that x and y are functions of time t such that x and y is a constant. So, we can write the following equation:

[tex]x(t)+y(t)=k,\text{ where $k$ is some constant}[/tex]

The rate of change of x and the rate of change of y with respect to time t is simply dx/dt and dy/dt, respectively. So, we will differentiate both sides with respect to t:

[tex]\displaystyle \frac{d}{dt}\Big[x(t)+y(t)\Big]=\frac{d}{dt}[k][/tex]

Remember that the derivative of a constant is always 0. Therefore:

[tex]\displaystyle \frac{dx}{dt}+\frac{dy}{dt}=0[/tex]

And by subtracting dy/dt from both sides, we acquire:

[tex]\displaystyle \frac{dx}{dt}=-\frac{dy}{dt}[/tex]

Hence, our answer is B.

Answer:

Let x and y be functions of time t such that the sum of x and y is constant.

Answer:

25 degrees

Step-by-step explanation:

angle CAD is a right angle, which is 90 degrees, and angle CAF is a straight line (180 degrees), which makes angle DAF a right angle. It is given that angle EAF is 65 degrees, therefore,

90 degrees - 65 degrees =  25 degrees

Answer:

x=3

Step-by-step explanation:

Answer:

so 9 - x - 5x = 9 because the 9 means x so its making the number negative. so - 9 and the 9 at the end = 9 don't worry about that bc you can subtract 5x

Step-by-step explanation: so what I'm saying is theirs many ways to solve that its just you don't know the level or something similar to that I'm only helping because I'm bored btw.

Answer:   a = [ 65.8]

Step-by-step explanation:

A = 18°

B = 28°

b = 100

a = [ x ]

[tex]\dfrac{100}{sin \: 28^{o} } =\dfrac{x}{sin \: 18^{o} } \\\\\dfrac{100}{0.4694715628} =\dfrac{x}{0.3090169944} \\\\x=\dfrac{0.3090169944 \cdot 100}{0.469715628} \\\\x=65.78810\dots \\x \approx 65.8[/tex]

Answer:

Total Proper Subsets = 2ⁿ - 1 = 2³ -1 =8-1 =7

Step-by-step explanation:

Basically the formula for,

No of subsets = 2ⁿ

Where n is number of elements in a set. As one subset is improper which is equal to the set itself so we have to find proper subsets which are = 2ⁿ - 1.

Step-by-step explanation:

Answer:

Yes, x = 1/2 is a solution

Step-by-step explanation:

To see if it is a solution, plug it into the equation:

3(x + 1) = 3x + 3

3(0.5 + 1) = 3(0.5) + 3

3(1.5) = 1.5 + 3

4.5 = 4.5

Since this is true, x = 1/2 is a solution of the equation.

Step-by-step explanation:

If there are 20 yellow marbles,

there must be 32 - 20 = 12 red marbles.

P(Red marble)

= 12/32

= 0.375.

Answer:

The probability is 12/32

Step-by-step explanation:

If there are 12 red marbles and 20 yellow marbles, then there will be a 12/32 chance that you pick a red marble

This is because out of 32 marbles, you have 12 red marbles that you could pick, which gives you a 12/32 chance that you will pick a red marble. This can also be said as a 37.5% chance.

Answer:

x = 15

Step-by-step explanation:

Apply the keg rule to find x. The keg rule is given as:

Hypotenuse / leg = leg / part of the hypotenuse directly under the leg

Hypotenuse = 25

Leg = x

Part of the hypotenuse directly under the leg = 25 - 16 = 9

Plug in the values

25/x = x/9

Cross multiply

x*x = 25*9

x² = 225

x = √225

x = 15

Answer:

[tex]8\:\mathrm{minutes}[/tex]

Step-by-step explanation:

The volume of a cylinder is given as:

[tex]r^2\cdot\pi\cdot h[/tex]

Since the diameter is [tex]2.2[/tex], the radius is [tex]\frac{2.2}{2}=1.1[/tex].

Therefore, the volume of this cylinder is:

[tex]1.1^2\cdot 3.14\cdot 4=15.1976\:\mathrm{ft^3}[/tex], using [tex]\pi=3.14[/tex] as requested in the problem.

Since the tank is emptied at a constant rate of [tex]1.5\:\mathrm{ft^3\:per\:minute}[/tex], it will take

[tex]\frac{15.1976}{1.5}=7.5988=\fbox{$8\:\mathrm{minutes}$}[/tex] to empty the tank.

140 divided by -8=-17.5

x=-17.5

Answer:

VX = 37

Step-by-step explanation:

Since VX is the midsegment, based on the midsegment theorem we would have:

VX = ½(UY)

VX = s - 37

UY = s

Plug in the values

s - 37 = ½(s)

Multiply both sides by 2

2(s - 37) = s

2s - 74 = s

Collect like terms

2s - s = 74

s = 74

VX = s - 37

Plug in the value of s

VX = 74 - 37 = 37
