Berniece solved the following equation:

Mathematics
1 answer:
Ghella [55]3 years ago
6 0

Step 4 is incorrect.

This is technically another example of the subtraction property of inequality. This is because we are subtracting 8 from both sides to get the 8 to cancel and the 24 to go down to 16. This is not addition and should not be justified as such.

Evelyn can run 3 miles in 40 minutes. Which equation can be solved to find m, the number of miles Evelyn can run in 60 minutes?
inna [77]

Answer:

m= 4.5 miles

Step-by-step explanation:

Let the number of miles Evelyn can run be m and can be modeled by the equation below

m= kx

Where x Is the Minutes

When m= 3

x= 40

3= k40

k= 3/40

If x= 60

m=3/40(60)

m = (60*3)/40

m= 180/40

m= 4.5 miles

Translate the statements into a confidence interval for p. Approximate the level of confidence. In a survey of 8451 U.S. adults,
Sedaia [141]

Answer:

The  confidence interval is  0.304 <  p  < 0.324

Step-by-step explanation:

From the question we are told

      The sample proportion \r p  =  0.314

      The margin of error  is E =  0.01

The confidence interval for  p is mathematically represented as

       \r p -  E  <  p  < \r p + E

=>    0.314 -  0.01  <  p  < 0.314 +  0.01

=>   0.304 <  p  < 0.324
