What is the slope of the line that passes through the points (2, -3) and (2, 13)
Write your answer in simplest form.

Answer:

it is the 1st one

Step-by-step explanation:

because you have to add up all three sides  because you need 180 then subtract that answer from 180 and you will get your answer

Answer:

the answer is J

Step-by-step explanation:

Answer:H

find the slope

Answer:

Step-by-step explanation:

When x=-2; y = -16+12= -4. This means a=-4

When x=-1; y= -2+3 = 1. This means b= 1.

When x=2; y = 16 +12 = 28 . This means c= 28

When x=4; y= 128+48 = 176. This means d= 176

Answer:

d = 140t

Step-by-step explanation:

The function that relates the distance travelled d to the time t is d = f(t) = 140t.

Speed is a scalar quantity which measures the rate of change of the position of an object without measuring on the direction.

In other words, it can be defined as the ratio of distance covered by an object to the time taken by the object to cover the distance.

The train leaves the station at time t = 0.

Distance travelled by the train = 280 kilometers

Time taken to travel the distance = 2 hours

Speed = Distance / Time

           = 280 / 2

           = 140 kilometers/ hour.

Given that train travels at a constant speed.

So for any distance 'd' and the time taken to travel the distance 't',

d / t = 140

d = 140t

d = f(t) = 140t

Hence the distance travelled by the train can be related to the time taken by the function, d = f(t) = 140t

Answer:

The calculated value    Z = 1.183 < 1.96 at 0.05 level of significance

Null hypothesis is accepted

A particular greyhound breeder claims that her dogs are faster than the average greyhound

Step-by-step explanation:

Step(i):-

Given the average speed of greyhound dogs is about 18.4 meters per second.

Size of the sample 'n' = 35

mean of the sample x⁻ = 18.7

Population standard deviation = 1.5m/s

level of significance (∝)  = 0.05

Step(ii):-

Null hypothesis : H₀ : μ = 18.4

Alternative  hypothesis H₁ :  μ ≠ 18.4

Test statistic

              [tex]Z = \frac{x^{-} - mean}{\frac{S.D}{\sqrt{n} } }[/tex]

             [tex]Z = \frac{18.7-18.4}{\frac{1.5}{\sqrt{35} } }[/tex]

            Z = 1.183

Conclusion:-

The calculated value    Z = 1.183 < 1.96 at 0.05 level of significance

Null hypothesis is accepted

Answer:

a

 [tex]P( X > 46) = 0.7 \ minute[/tex]

b

[tex]\mu = 42 \ minute[/tex]

Step-by-step explanation:

From the question we are told that  

   The procedure for performing a certain task is uniformly distributed on the interval from( a =  32 )minutes to (b= 52) minutes

  Generally the cumulative distribution function for continuous uniform distribution is  

             [tex]F(x) = \left \{ {{0 \ \ \ \ \ for \ x \ x < a} \atop {\frac{x-a}{b-a} } \ \ for \ a \le x \ge b} \atop {1 \ \ \ \ \ \ \ for \ x > b }\right.[/tex]

Generally the probability that it takes more than 46 minutes to learn the procedure is mathematically represented as

          [tex]P( X > 46) = F(46) = \frac{46 - 32}{52-32}[/tex]

=>       [tex]P( X > 46) = 0.7 \ minute[/tex]

Generally the average time required to learn the procedure is mathematically represented as

        [tex]\mu = \frac{a + b}{2}[/tex]

=>     [tex]\mu = \frac{32 + 52}{2}[/tex]

=>     [tex]\mu = 42 \ minute[/tex]

posistive i think welp hope this helps :D

Step-by-step explanation:

Answer:

M<E = 62°

Step-by-step explanation:

Since (8x-34)° and (5x+2)° are alternate interior angles, it means they equal each other so...

(8x-34)°= (5x+2)°

if you drop the parenthesis, you get

8x-34= 5x+2

Then you just solve and simplify it

3x= 36 ----> x= 12

Now you know what x is, you would plug it in to either one and you get 62 as your answer meaning m<E is 62°

8(12)-34= 62 (since this angle and angle E are parallel, the angles are the same and that is why if you plug x into this equation, you can find out what the angle of E is)

5(12) +2= 62 ( and since this angle is across from angle E, it means the angles are the same... so that's why if you plugged in x which is 12 into this equation, you can also find E)

Answer:

The table is:

x        y

1         1

2        5

3        9

The graph B shows the relationship y=4x-3

Step-by-step explanation:

We need to fill the table using the rule:

To find y multiply x by 4 and then subtract 3.

Writing rule in mathematical form:

y=4x-3

Now for completing the table we need to put x=1,2 and 3 and find values of y

[tex]For x=1//y=4x-3\\ y=4(1)-3\\ y=4-3\\ y=1\\[/tex]

[tex]For \ x=2\\y=4x-3\\ y=4(2)-3\\ y=8-3\\ y=5[/tex]

[tex]For \ x=3\\y=4x-3\\ y=4(3)-3\\ y=12-3\\ y=9[/tex]

So, the table is:

x        y

1         1

2        5

The graph B shows the relationship y=4x-3

Answer:

994

Step-by-step explanation:

We have the expression:

[tex](8+t)^3-6[/tex]

And we want to evaluate it when t=2.

Hence, we will substitute 2 for t and evaluate. Therefore:

[tex]=(8+2)^3-6 \\\\ =(10)^3-6\\ \\ =1000-6\\\\=994[/tex]

Therefore, our final answer is 994.
