Answer:

m<5 = 115

Step-by-step explanation:

This is vertical angle so, 115-50=65

So measure angle 1 is 65 degrees.

These are corresponding angles so 50+65=115

Therefore, m<5 = 115

A bucket of paint has spilled on a tile floor. The paint flow can be expressed with the function r(t) = 3t, where t represents time in minutes and r represents how far the paint is spreading.

The flowing paint is creating a circular pattern on the tile. The area of the pattern can be expressed as A(r) = πr2.

Part A: Find the area of the circle of spilled paint as a function of time, or A[r(t)]. Show your work.

Part B: How large is the area of spilled paint after 10 minutes? You may use 3.14 to approximate π in this problem.

Answer:

to differential calculus, because I don't know how to answer this question without

using it.

We're told that Jason's height above the water is  H(t) = -16t² + 16t + 480 .

We can observe many things from this equation:

-- Up is the positive direction; down is the negative direction.

-- The acceleration of gravity is 32 ft/sec² .

-- Jason jumps upward from the cliff, at 16 ft/sec .

-- The cliff is 480-ft above the water.

(This tells us why the question is only concerned with his maximum height,

and then it ends ... 480-ft is one serious cliff, and what happens after the

peak of his arc is too gruesome to contemplate.)

In any case, his vertical velocity is the first derivative, with respect to time,

of his height above the water.

        V = -32 t + 16

At the peak of his arc, where gravity takes over, his velocity changes from

upward to downward, and it's momentarily zero.

                                          0 = -32t + 16

Add  32t  to each side:    32t = 16

Divide each side by  32:      t = 1/2 second

His height at that instant is     H(0.5) = -16(0.5)² + 16(0.5) + 480 =

                                          4-ft above the cliff,  484-ft above the water,

and then he begins falling from that altitude.

The duration of his dive is      484 = 16 t²

                                                  t = √(484/16) = 5.5 seconds

and he hits the water at      V = a t = (32) x (5.5) = 176 ft/sec = exactly 120 mph

The final question is;

Why is it not appropriate to calculate a two-sample z-interval for a difference in proportions?

Answer:

The normality of the sampling distribution of the difference in sample proportions cannot be established.

Step-by-step explanation:

To use the two-sample z-interval for a difference in proportions, some conditions must be met which help us to know the normality of the distribution.

The conditions are;

- The method of sampling for each population must be simple random sampling.

- The samples must be independent.

- Each sample must include at least 10 successes and 10 failures.

- Each population must be a minimum 20 times its sample.

In this case, we are not given the population size and as such we cannot ascertain the last condition I wrote above since the sample proportion we are given alone isn't sufficient. Also, they both don't include at least 10 failures. Thus the normality of the sample proportions cannot be established.

Answer: the normality of the sampling distribution of the difference in sample proportions cannot be established

Answer:

work out the area which is 4x5x3 this being 60 then divide this by 20 to get 3

The answer is 3kg

Answer:

[tex]density = mass \div volume \\ 20 = x \div 4 \times 3 \times 5 \\ 20 = x \div 60 \\ 20 \times 60 = x \\ x = 1200 \\ 1200 \div 1000 = 1.2kg[/tex]

Answer:

y = -2x - 1

Step-by-step explanation:

If you already know the slope. Just find out the y-intercept. Plug the coordinates into the equation.

y = mx + b

y = -2x + b

1 = -2(1) + b

1 = -2 + b

-1 = b

Answer:

y = 1/ 3 x − 1

Step-by-step explanation:

y intercept is -1 and slope is 1/3x

The slope and y-intercept will be [tex]\rm m=\frac{1}{3} \ and \ c=-1[/tex]. The slope and the intercept are found with the help of the standard equation;

A numerical assessment of a line's angle relative to the ground is known as the slope.

The inclination of any line, ray, or line segment is the fraction of the perpendicular to the horizontal distance between any two positions on it.

The given linear equation in the problem is;

[tex]\rm 3x = 9y-9[/tex]

On dividing the whole equation  by 3 we will get;

[tex]\frac{1}{3} x=y-1 \\\\ y= \frac{1}{3} x+1[/tex]

Compare the equation with the standard equation;

[tex]\rm y = mx+c[/tex]

Where m is the slope and c is the intercept. After comparing we will get;

[tex]\rm m=\frac{1}{3} \\\\ c=-1[/tex]

Hence the slope and y-intercept will be [tex]\rm m=\frac{1}{3} \ and \ c=-1[/tex].
