Answer:

3 is the slope and -1 is the y intercept

Step-by-step explanation:

y= -1+3x

Using the slope intercept form

y = mx+b where m is the slope and b is the y intercept

y = 3x-1

3 is the slope and -1 is the y intercept

Answer: 3

Step-by-step explanation:

1: Convert to Slope-Intercept Form

y=3x-1

2: When y=mx+b, m= slope, thus, the slope is 3.

A local company wants to evaluate their quality of service by surveying their customers.

Answer: b. 0.98

Step-by-step explanation:

The formula to find the maximum error of the estimated mean :

$E=z^*\dfrac{\sigma}{\sqrt{n}}$ (1)

, where $\sigma$ = standard deviation

n= Sample size

z* = Critical z-value.

As per given , we have

$\sigma=5$

n=100

Critical value for 95% confidence interval = z*=1.96

Put these values in the formula (1), we get

$E=(1.96)\dfrac{5}{\sqrt{100}}$

$E=(1.96)\dfrac{5}{10}=0.98$

Hence, the maximum error of the estimated mean quality for a 95% level of confidence is 0.98.

Therefore , the correct answer is b. 0.98 .

Dilate ABC below using A as the center and a<br> scale factor of 2. Leave all construction marks?

<h3>Answer: Check out the diagram below.</h3>

Explanation:

Use your straightedge to extend segment AB into ray AB. This means you'll have it start at A and go on forever through B. Repeat these steps to turn segment AC into ray AC.

The two rays join at the vertex angle A. Point A is the center of the universe so to speak because it's the center of dilation. We consider it an invariant point that doesn't move. Everything else will move. In this case, everything will move twice as much compared to as before.

Use your compass to measure the width of AB. We don't need the actual number. We just need the compass to be as wide from A to B. Keep your compass at this width and move the non-pencil part to point B. Then mark a small arc along ray AB. What we've just done is constructed a congruent copy of segment AB. In other words, we've just double AB into AB'. This means the arc marking places point B' as the diagram indicates.

The same set of steps will have us construct point C' as well. AC doubles to AC'

Once we determine the locations of B' and C', we can then form triangle A'B'C' which is an enlarged copy of triangle ABC. Each side of the larger triangle has side lengths twice as long.

Note: Points A and A' occupy the same exact location. As mentioned earlier, point A doesn't move.
