Answer:

first side=40

second side=20

third side=22

Step-by-step explanation:

LET THE SIDES OF THE TRIANGLES BE y

Perimeter=82

first side=2 x y = 2y

second side=y

third side=2 +y

2y + y + 2 + y=82

4y+2=82

4y= 82-2

4y=80

y=80/4

y=20

first side=2y=2(20)=40

second side=y=20

third side= 2 + y= 2 + 20 = 22

Answer:

Area of rectangle box = 2,920 CM²

Step-by-step explanation:

Given:

Length = 42 Cm

Width = 20 Cm

Height = 10 Cm

Find:

Total area required to make box = ?

Computation:

Area of rectangle box = 2[LB + BH + HL]

Area of rectangle box = 2[(42 × 20) + (20 × 10) + (10 × 42)]

Area of rectangle box = 2[(840) + (200) + (420)]

Area of rectangle box = 2[1,460]

Area of rectangle box = 2,920 CM²

The manager of a supermarket wants to obtain information about the proportion of customers who dislike a new policy on cashing c
alex41 [277]

Answer:

n = 61 costumers

Step-by-step explanation:

For calculating the number of costumers he should sample we use the next equation:

n = \frac{z_{1-\alpha/2}^{2}p(1-p)}{E^{2} }

                          Where E is the error that we are prepared to accept, in this  case E = 0.15

How we don't know the value of p, we can estimate it like p = 0.5

∝ = 1-0.98 = 0.02

1-∝/2 = 0.99

z_{0.99} = 2.33

n = \frac{(2.33^{2})(0.5)(1-0.5)}{0.15^{2} }

n = 60.32 costumers

n ≈ 61 costumers
