Each shelf holds 5 hermit-crab cages and 3 hermit-crab care booklets. If there are 23 hermit crab cages and 12 booklets to displ
Harrizon [31]

1. Each shelf holds 5 hermit-crab cages. There are 23 hermit crab cages to be displayed. Divide the number of hermit crab cages to be displayed by the number of hermit crab cages that can be displayed on each shelf:

23=5\cdot 4+3.

This means that you need 5 shelves (4 shelves is not enough, because 3 hermit crab cages will be not displayed).

2. Each shelf holds 3 hermit-crab care booklets. There are 12 hermit-crab care booklets to be displayed. Divide the number of hermit-crab care booklets to be displayed by the number of hermit-crab care booklets that can be displayed on each shelf:

12=3\cdot 4.

This means that you need 4 shelves.

Answer: first, you have to divide 23 by 5 and find the quotient and remainder and divide 12 by 3 and find the quotient and remainder. Then you have to determine the number of shelves needed. You need 5 shelves.

16. A large-sample 95 percent confidence interval for the proportion of credit
borishaifa [10]

Answer:

(B) 0.057

Step-by-step explanation:

The 95% confidence interval is (0.028, 0.086). The formula for the confidence interval is μ ± e where μ is the mean and e is the margin of error.

Therefore the confidence interval is (μ - e , μ + e).

That is μ - e = 0.028 and μ + e = 0.086

To get the point estimate which is the mean, we sum the two proportions and divide it by two.

Therefore point estimate (μ) = (0.028 + 0.086) / 2 = 0.057

Whats the abswer to 1/2x+3/4=1
g100num [7]
<em>*Because of BODMAS, 1/2x=x/2.</em>

1/2x+3/4=1

1/2x+3/4=4/4

1/2x=4/4-3/4

1/2x=1/4

x/2=1/4

x=2/4

x=1/2

Find slope (y2-y1)/(x2-x1)
Pick points: (1,10) , (2,8)
(8-10)/(2-1) = -2/1 = -2
Y = -2x + b
10 = -2 + b, b = 12
It would be the first response
12 = initial while -2 is rate of change

guys i need help with solving the system of equations and combining the equations. also show your work. the equations are x-4y=-
Firdavs [7]
X-4y=-12
4x-y=12

eliminate y's
multily 2nd equaiton by -4 and add to top one

x-4y=-12
<u>-16x+4y=-48 +
</u>-15x+0y=-60

-15x=-60
divide both sides by -15
x=4
sub back
x-4y=-12
4-4y=-12
minus 4 both sides
-4y=-16
divide both sides by -4
y=4

x=4
y=4
