The probability that a person chosen at random, who lives in the city, lives in the central or north region is 0.56

A probability is a number that reflects the chance or likelihood that a particular event will occur.

Given that, the Probability distribution table shows the proportion of people living in five different regions of a city

Probability = Favourable Outcomes/Total Outcomes

Probability(of selecting a person from central or north region) = 0.44 + 0.12 = 0.56

Hence, probability that a person chosen at random, who lives in the city, lives in the central or north region is 0.56

Answer:

−21.573x

Step-by-step explanation:

simplify it

Answer:

m=1

Step-by-step explanation:

y=mx+b

m = y 2 − y 1/ x2 − x 1

m = − 4 − ( − 10 )/ 10 − ( 4 )

m = − 2 − 5 ⋅ − 1/ − 1 (− 5 + 2 )

m = 3 − 1 /( − 5 + 2 )

Add  

− 5  and  2

m =  3/ − 1 ⋅ − 3

Multiply  

− 1  by  − 3

m = 3/ 3

Divide  3  by  3 .

m = 1

Hope this helps!

Explanation:

If y is the short leg of the 30-60-90 triangle, then y*sqrt(3) is the length of the longer leg. The short leg is always opposite the shortest angle.

We're given that 5*sqrt(3) is the longer leg, so

y*sqrt(3) = 5*sqrt(3)

y = 5

After we divide both sides by sqrt(3)

Side note: x = 2y = 2*5 = 10.

Heya mate!

If you observe the figure, the longest side always resides the opposite place of the right angle. Accordingly the perpendicular is 5√3 units in measure.

With this, the hypotenuse is x and the base is y. We need to find y. By doing some smart work! Let's guess the trigonometric ratio that we give us the relation between y and 5√3 because one of the angle given is 60°

⇛ tan a = Perpendicular / Base

Plugging the values of a, and Perpendicular to find the base of the triangle i.e. y.

⇛ tan 60° = 5√3 / y

⇛ √3 = 5√3 / y

⇛ y = 5√3 / √3

⇛ y = 5 units

Hence, the Correct Option is Option A.

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

The answer is choice C it's the only one that actually touches point (0, -7) and increases after that point.

Graph 1:

If we take a look at graph 1 we see that it does cross the y-axis at (0,-7), but sadly it doesn't increase.

Graph 2:

If we take a look at graph 2 we see that it does cross over y-axis but not at (0,-7). It also doesn't increase but that doesn't matter anymore.

Graph 3:

If we take a look at graph 3 we see that it crosses the y-axis at (0,-7) and it also increases. Although it decreases before it doesn't matter, it only has to increases after it hits (0,-7).

Answer:

It would cost the much $10.94500 for it all.

Step-by-step explanation:

Here is the full question.

In city A, the temperature rises 9° F from A.M to 9 A.M. Then the temperature drops 8°F from 9 A.M. to 10 A.M. in city B, the temperature drops 1°F from  8 A.M. to 9 A.M. Then the temperature drops 3°F from 9 A.M. to 10 A.M.

Write an expression that represents the change In temperature from  8 A.M. to 10 A.M for each city. Simplify and interpret each sum. Use a pencil and paper. Which expression represents the change in temperature for city A?

Answer:

In City A, the expression for the change in temperature is = 9 + (-8)

The amount the temperature changes for City A = 1°F

In City B, the expression for the change in temperature is -1 + (-3)

The amount the temperature changes for City B = -4°F

Thus, City A has a greater change in temperature.

Step-by-step explanation:

From the information above; Given that:

In City A, the rise in temperature from 8 A.M to 9 A.M is = 9°F

In City A, the drop in temperature from 9 A.M to 10 A.M = 8°F

Similarly;

In City B, the drop in temperature from 8 A.M to 9 A.M = 1°F

In City B, the drop in temperature from 9 A.M to 10 A.M = 3°F

∴

For City A

The temperature change from 8 A.M to 10 A.M are :

8 A.M to 9 A.M = +9°F

9 A.M to 10 A.M = -8°F

In conclusion, The sum for the change from 8 A.M to 10 A.M = 9 + (-8) = 1°F

For City B

The temperature change from 8 A.M to 10 A.M are:

8 A.M to 9 A.M = -1°F

9 A.M to 10 A.M = -3°F

In conclusion, The sum for the change from 8 A.M to 10 A.M = -1 + (-3) = -4°F

Step-by-step explanation:

Let

The event where a car has air conditioning (ac) be A

The event where a car has an automatic transmission be B

[tex]P(\text{Car has ac and cars that don't have automatic transmission})=P(A\cap B')=\dfrac{71}{136}[/tex]

[tex]P(\text{Car has car has an automatic transmission and no ac})=P(B\cap A')=\dfrac{56}{136}[/tex]

[tex]P(\text{Car has no ac and cars that don't have automatic transmission})=P(A'\cap B')=\dfrac{9}{136}[/tex]

The probability of a chosen car which has ac or automatic transmission or both

[tex]P(A\cup B)=1-P(A\cup B)'\\\Rightarrow P(A\cup B)=1-P(A'\cap B')\\\Rightarrow P(A\cup B)=1-\dfrac{9}{136}\\\Rightarrow P(A\cup B)=0.93382[/tex]

The probability that a randomly selected car had automatic transmission or air conditioning or both is 0.93382

Answer:

Jules would need 30 yards of fencing.

The yards of fencing that would be needed is 30√2 yards.

In order to determine the length of the fence, the Pythagoras theorem would be used.

The Pythagoras theorem: a² + b² = c²

where:

a = length

b = base

c = hypotenuse

30²  + 30²

= 900 + 900

= √1800

= 30√2 yards

Step-by-step explanation:

The slope-intercept form of the equation is y = (4/5)x -1.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given that slope=4/5 passing through (5,3). The equation of the line can be written as,

y = mx + c

3 = ( 4 x 5/5) + c

c =-1

The equation will be:-

y = mx + c

y = (4/5)x -1
