State the slope and the y-intercept for the graph of each equation.
1 answer:
Slope and y-intercept section:
<em>2. y=2x-2</em>
<em>Slope: 2</em>
<em>Y-intercept: -2</em>
<em>4. y=-x+3</em>
<em>Slope: -1</em>
<em>Y-intercept: 3</em>
<em>6. y=-1/3x+4</em>
<em>Slope: -1/3 (negative one third)</em>
<em>Y-intercept: 4</em>
<em>8. y+4x=2</em>
<em>Slope: -4</em>
<em>Y-intercept: 2</em>
Graphing section:
<em>y=mx+b where m = slope and b = y intercept</em>
<em>10. Graph a line with the slope of 1 and y-intercept of -4</em>
<em>slope form: y=1x+-4 </em>

Hello! Recall you need to write complete questions in order to find exact answers. So in this problem I'll assume the question is:
<em>A number d minus 4 is less than -1</em>
<em />
So it is easy to know that we need to write an inequality here because of the words "less than", which implies that we must use the symbol <. So let's solve this step by step.
Step 1. A number d minus 4.
This statement includes the word "minus", so we need to use the symbol (-). Therefore:
Step 2. A number d minus 4 is less than
As we said above, here we need to use the symbol (<). So:
Step 3. A number d minus 4 is less than -1
Finally, we get:

Answer:
H0: μ ≤ 34
H1: μ > 34
The z-test statistic is ≈ 1.8
The critical z-score is 1.28
we fail to reject the null hypothesis H0: μ ≤ 34
Step-by-step explanation:
H0: μ ≤ 34
H1: μ > 34
The z-test statistic is calculated using the formula:
z= where
- X is the average class size found in the sample (35.6)
- M is the mean according to the null hypothesis (34)
- s is the standard deviation for class size (9)
then z= ≈ 0.18
The critical z-score is 1.28 for α=0.10 (one tailed)
Because the test statistic is less than the critical value, do not reject the null hypothesis.
