-7x -7y = 21
Y = 6
Since they are giving you the value of 6 you just plug it in the equation
-7x - 7(6) = 21
-7x - 42 = 21
+ 42. +42
-7x = 63
/-7. /-7
X = -9
Answer:
1.) A
2.) D
3.) A
Step-by-step explanation:
Answer:
The slope intercept form is y=mx+c
So,
x=4y+2 should also be made in that form
x-2=4y
y=(x-2)/4
That’s the final answer in slope intercept form
Answer:
D. We are 95% confident that between about 22% and 28% of ESPN Viewers thought the Eagles would still win the division.
Step-by-step explanation:
We have to calculate a 95% confidence interval for the population proportion. The population is made up of ESPN viewers.
The sample proportion is p=0.25.
The standard error of the proportion is:
The critical z-value for a 95% confidence interval is z=1.96.
The margin of error (MOE) can be calculated as:
Then, the lower and upper bounds of the confidence interval are:
The 95% confidence interval for the proportion of ESPN viewers is (0.222, 0.278) or (22.2%, 27.8%).
Given:
- total number of masks= 200
- cost of 1 mask= Rs. 5
so, total cost fir 200 masks=
200×5
= 1000
therefore, Joe paid Rs. 1000 altogether.
