Answer:

<em>i got u</em>

<em>Answer: </em>

<em>The slope is  </em>

<em>− 2 5 . </em>

<em>The y-intercept is  </em>

<em>1 . </em>

<em>The point is  </em>

<em>( 0 , 1 ) . </em>

<em>The x-intercept is  </em>

<em>2 5 . </em>

<em>The point is  </em>

<em>( 2 5 , 0 ) . </em>

<em> </em>

<em>Explanation: </em>

<em>y < − 2 5 x + 1 </em>

<em> is in the slope-intercept form of a linear equation,  </em>

<em>y = m x + b , where  m </em>

<em> is the slope and  b </em>

<em> is the y-intercept. The y-intercept is the value of  y </em>

<em> when  x  is  0 . </em>

<em>Find the  </em>

<em>x  and  y </em>

<em> intercepts. </em>

<em> </em>

<em>The y-intercept is  + 1 . </em>

<em> </em>

<em>The point for the y-intercept is  </em>

<em>( 0 , 1 ) . </em>

<em>Find the  x </em>

<em> intercept by substituting  </em>

<em>0  for  y </em>

<em> and solving for  </em>

<em>x .  0 = − 2 5 x + 1  </em>

<em>Subtract  1 </em>

<em> from both sides. </em>

<em> − 1 = − 2 5 x </em>

<em> </em>

<em>Multiply both sides by  </em>

<em>5 5 × − 1 = − 2x − 5 = − 2 x </em>

<em> </em>

<em>Divide both sides by  − 2 .  − 5 − 2 = x5 2 = x  </em>

<em>Switch sides. </em>

<em> x = 5 2 </em>

<em>The x-intercept is  </em>

<em>5 2 . </em>

<em>The point for the x-intercept is  </em>

<em>( 5 2 , 0 ) . </em>

<em> </em>

<em>Plot the two points on a graph. Draw a straight dashed line through the points to indicate that the line is not part of the inequality. Then shade the area below the line. </em>

<em> </em>

<em>graph{y<-2/5x+1 [-10, 10, -5, 5]}</em>

4k – 3 = -2k + 3 help me please lol
hoa [83]

Answer: k=1

Step-by-step explanation:

4k-3=-2k+3

take -3 and 3 and add them up on one side and change the sign

4k=-2k+3

           +3

4k=-2k+6

take the -2k and change the sign and add to 4k

4k=6

2k

6k=6

now divide both sides with x

6k/6= 6/6

k= 1

An airplane takes off from the ground and reaches a height of 500 feet after flying 2 miles. given the formula h = d tan θ, wher
zloy xaker [14]

Height covered by the plane=h= 500 feet

Distance covered by the plane along the ground=d= 2 mile

Now, convert the mile into feet,

1 mile = 5280 feet

2 mile = 10560 feet

Now, use the formula

h= d tanθ

tanθ= h/d

tanθ= 500/10560

tanθ= 25/528

Take the tan⁻¹ on both side,

θ= tan⁻¹(25/528)

θ =2.71°

We are interested in finding out the proportion of adults in the United State who cannot cover a $400 unexpected expense without
serious [3.7K]

Answer:

Step-by-step explanation:

given that we are interested in finding out the proportion of adults in the United State who cannot cover a $400 unexpected expense without borrowing money or going into debt.

Sample size = 765

Favour = 322

a) The population is the adults in the United State who cannot cover a $400 unexpected expense without borrowing money or going into debt

b) The parameter being estimated is the population proportion P of adults in the United State who cannot cover a $400 unexpected expense without borrowing money or going into debt.

c) point estimate for proportion = sample proporiton = \frac{322}{765} \\=0.4209

d) We can use test statistic here as for proportions we have population std deviation known.

d) Std error = 0.01785(\sqrt{\frac{pq}{n} }

Test statistic Z = p difference / std error

f) when estimated p is 0.50 we get Z = -4.43

g) Is true population value was 40% then

Z = 1.17 (because proportion difference changes here)
