Answer:

c. 106 million

Step-by-step explanation:

A = number of people in the sample that use public transportation 5 or more days per week

A = 2,067,153

B = number of people total in the sample

B = 4,295,280

C = proportion of those in the sample that use public transportation 5 or more days per week

C = A/B

C = (2,067,153)/(4,295,280)

C = 0.48126 approximately

Multiply this value by the figure 220 million to compute the estimated number of people who use public transportation 5 or more days per week

C*(220 million) = 0.48126*(220 million) = (0.48126*220) million = 105.8772 million = 106 million

Answer:

60.2 m

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you ...

Tan = Opposite/Adjacent

The width of the river is the side of a right triangle opposite the angle of 76°. The 15 m distance is the length of the side adjacent to the measured angle. So, we have ...

tan(76°) = width/(15 m)

Multiplying by 15 m, we get ...

width = (15 m)tan(76°) ≈ 60.2 m

The width of the river is about 60.2 m.

Answer:

Option B. 5.5 ft²

Step-by-step explanation:

Perimeter of the square piece of land = length of fence required

4(length of a side of the square) = 24 ft

Length of a side = 6 ft

Area of the square land = (Side)²

= 6²

= 36 square ft

Area of the side walk = Area of the square - [Area of two triangles separated by the sidewalk]

= 36 - [1/2 (Area Of The Sqaure) + 1/2 (Base) (Height) ]

= 36 - [36/2 + 1/2 (6 - 1) (6 - 1)]

= 36 - (18 + 12.5)

= 36 - 30.5

= 5.5 ft²

Therefore, Option B. is the correct answer.

STEAM: The boiling pint of water is affected by changes in elevation. Use the expression of -2A/1000 where a represents the alti

damaskus [11]

Answer:

A) -10°F

Step-by-step explanation:

Given that:

Boiling point of water gets affected when there is a change in the elevation.

Expression to represent the temperature i.e. boiling point w.r.to altitude $A$ is given by the equation:

Temperature in $^\circ F$ = $\frac{-2A}{1000}$

Given that, the altitude, $A$ = 5,000 feet

To find:

The number of degrees Farenhite at which the boiling point of water will change.

Solution:

Here, we are given the expression:

Temperature in $^\circ F$ = $\frac{-2A}{1000}$

And value of altitude, $A$ = 5,000 feet

Let us put the value of $A$ in the equation and let us find the value of temperature in $^\circ F$ .

Temperature in $^\circ F$ =

$\frac{-2\times 5000}{1000}\\\Rightarrow -2\times 5\\\Rightarrow \bold{-10^\circ F}$

Therefore, the answer is:

A) -10°F

Answer: (2, 3) and (4,2) are not equal.

Step-by-step explanation:

An ordered pair is something like (x, y)

and two pairs (x1, y1) and (x2, y2) are only equal if x1 = x2 and y1 = y2

in this case, we have (2, 3) and (4, 2)

you can see that in the pairs the value of x is different, and the value of y is also different. Then we have that the pairs can not be equal.

Formula for probability
$\frac{given \: number}{total \: number} \times 100$
Theorically probability will be equal for all cases, that means each case will have a 25% chance
Now we will find the probability experimentally
Given number = 28
Total number = 100
28/100 × 100 = 28%

Since Theorically it is 25 and experimentally it is 28, The experimental probability is 3 % higher
Therefore the answer is the first option (the one u marked randomly)
Hope I helped... Please give me Brainlest answer
