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
Answer:
The error E = ± 4.04 %
Step-by-step explanation:
Solution:-
- The sample data is used to estimate the population proportion ( p ).
- The success p^ = success percentage = 40 %
- The confidence interval CI = 98%
- The sample size n = 800
- The margin of error E:
- The margin of error "E" for estimation of population proportion ( p ) is given by:

Where, Z-critical value is defined by the significance level:
P ( Z < Z-critical ) = α / 2
Where, α : Significance level
α = 1 - CI
P ( Z < Z-critical ) = (1 - 0.98) / 2
P ( Z < Z-critical ) = 0.01
Z-critical = 2.33
- The error E of estimation is:

- The error E = ± 4.04 %
Answer:
Solve for Y, then use either equation to find X
Step-by-step explanation:
360-275-20=65ratio 3:103x+10x=6513x=65x=55*3=15° and 5*10=50°15° and 50° are the other two angles
Since two sides are congruent, the opposite angles are congruent.
Angles A and B have the same measure.
m<A = m<B = 34
m<A + m<B m<C = 180
34 + 34 + m<C = 180
68 + m<C = 180
m<C = 112
m<C = 4y = 112
4y = 112
y = 28
