Answer:

39 touchdowns and 13 fieldgoals

Step-by-step explanation:

Let t= touchdowns

f = fieldgoals

They scored 35 times

t+f = 35

Touchdown is 7 pts and fieldgoal is 3 pt

7t+3f = 193

Multiply the first equation by-7

-7t -7f =-245

Add this to the second equation

-7t -7f =-245

7t+3f = 193

----------------------

-4f =-52

Divide by -4

-4f/-4 = -52/-4

f = 13

Now we can find t

t+f = 35

t+13 = 52

Subtract 13 from each side

t+13-13 =52-13

t =39

a senator wishes to estimate the proportion of united states voters who favor new road construction. what size sample should be

Nitella [24]

The size of the sample should be obtained at 2401 in order to be 95% confident

Given that:

Margi of error, $ME=0.02$

Population proportion, $p=0.50$

To Find: The size of the sample that should be obtained in order to be 95% confident

Let the size of the sample be n

Using formula,

$n=(p*(1-p))*(z(0.05/2)/ME)^{2} \\n=(0.5*(1-0.5))*(1.96/0.02)^{2} \\n=0.25*9604\\n=2401$

Therefore, the size of the sample should be obtained at 2401 in order to be 95% confident
