Answer: 4290 flyers
Step-by-step explanation:
The Volunteer Club has 78 people that are marching in a parade and each person is supposed to give out out 55 flyers about volunteering. To know the number of flyers that will be needed, we multiply the number of people by the number of flyers each person is holding. This will be :
Total number of flyers needed:
= 78 × 55.
= 4290
There will be 4290 flyers needed.
Answer:
88 units squared
The two triangles at the end make it a regular rectangle so you just multiply length by height. Hope this helps!
Step-by-step explanation:
Answer:
a)0.154<p<0.48[
b)n≅ 6.57
c)n=2401
Step-by-step explanation:
n = 60
Sample proportion = p = 16/60 = 0.266
a) Find a 95% two-sided confidence interval on the true proportion of helmets
90 % confidence interval fro population is
hence population proportion lies in the confidence interval
b) helmets must be tested to be 95% confident
point of estimates i s- 0.266
Margin of error = 0.02
after putting values we get
n = 6.56
n≅ 6.57
c)large must the sample be
The sample is calculted as
n=2401
Answer:
point slope form y+4 = -3(x+1)
slope intercept form y = -3x-7
Step-by-step explanation:
We have a point and a slope, we can use the point slope form for the equation
y-y1 = m(x-x1)
y--4 = -3 (x--1)
y+4 = -3(x+1)
We can also manipulate the equation into slope intercept form
Distribute
y+4 = -3x -3
Subtract 4 from each side
y+4-4 =-3x-3-4
y = -3x-7
