Answer:
y=4x+11
Step-by-step explanation:
multiply 4 into the parentheses to get y-3=4x+8 then invert -3 so add three to both sides to get rid of it so instead of +8 its +11 so now its y=4x+11 and slope intercept is y=mx+b, so 4 is m, slope, and 11 is b, the y intercept i hope that helps
Answer:
Null hypothesis: 
Alternative hypothesis: 
So we need to conduct a:
D. A two-sample z-test for a difference in population proportions
Because the idea is to check if the population proportions in the states are similar or not.
Step-by-step explanation:
For this case they are trying two proof if there is a significant difference between two states in the percents of high school students who order yearbooks, and we chan check this with the difference of proportions.
Lets say that 
are the two proportions of interest and we want to check the following hypothesis:
We have the following info given:
proportion of students that had ordered a yearbook from one state
proportion of students that had ordered a yearbook from another state
sample size from one state
sample size from another state
Null hypothesis:
Alternative hypothesis:
So we need to conduct a:
D. A two-sample z-test for a difference in population proportions
Because the idea is to check if the population proportions in the states are similar or not.
Answer:
No. The method is not fair.
<span>The
probability of pulling a gold or a silver for the first time is 1/10. The
probability of getting the same color the second time is 1/9. The probability
of getting a different color on the second pullout is still 1/10. Therefore,
the chance that same colors will be
pulled out is higher than that of different colors. Betty has an advantage in the drawing by 1.1%.</span>
Solution:
Probability of same color:
1/10+1/9
9/90+10/90
21.1%
Probability of different colors
1/10+1/10
2/10
20%
<span>21.1%-20%=1.1%</span>
Answer:
Step-by-step explanation:
y = 3x - 5.....input values are x and output values are y
so if ur input (x) is 2.....sub 2 in for x and find ur output (y)
y = 3x - 5
y = 3(2) - 5
y = 6 - 5
y = 1 <=== ur output value
