Slope intercept form is y=mx+b where m=slope and b=yintercept so
3x-7y=11
add 7y to both sideds
3x=11+7y
subtract 11 from both sides
3x-11=7y
divide both sides by 7
3/7x-11/7=y
y=3/7x-11/7
slope is 3/7
Don't you mean 66 divided by eight?
That would equal 8.25, or 8 remainder 2.
if you did mean 8 divided by 66, your answer is not one of your choices.
Answer:
the answer I got is false
Step-by-step explanation:
5/7=14 convert 14 to fraction 98/7
5/7=98/7 compare 5/7 and 98/7
so the maths is false question
Answer: Reject the eight- ounces claim.
Step-by-step explanation:
For left tailed test , On a normal curve the rejection area lies on the left side of the critical value.
It means that if the observed z-value is less than the critical value then it will fall into the rejection region other wise not.
As per given ,
Objective : A coffee-dispensing machine is supposed to deliver eight ounces of liquid or less.
Then ,
, since alternative hypothesis is left-tailed thus the test is an left-tailed test.
the critical value for z for a one-tailed test with the tail in the left end is -1.645 and the obtained value is -1.87.
Clearly , -1.87 < -1.645
⇒ -1.87 falls under rejection region.
⇒ Decision : Reject null hypothesis.
i.e. we reject the eight- ounces claim.
Perimeter- 14x+6
Just add al the sides up like normal
Area- 12x^2+9x
Multiply the length and width
C)
Perimeter- 118
Area- 840
I’m pretty sure these are right
