Answer:

The correct answer is k=1/5

Step-by-step explanation:

Given the expression " r varies directly as p", we need to find an equation that describes the relationship between both variables. First, we have that r varies as p varies, so r is the dependent variable and p is the independent variable. So

r = k x p ⇒ replacing with the given values (r =3 when p =15)

3 = k x 15 ⇒ 3/15 = k ⇒ 1/5 = k.

Then the constant of proportionality is k = 1/5.

A water-efficient washer costs $400 more than a regular washer and saves 100 l of water for each load. if water costs $5 per 1,0
Kruka [31]
8 years because its uses 100l per load and you wash 100 per year you multiply and get 10,000 which divided by 1,00 its 10 so 10 x 5 = 50 so you save 50 per year and its 400 dollars more so 50 x 8 years will be 400

A random sample of the amounts for 22 purchases was taken. The mean was ​$42.97​, the standard deviation was ​$22.82​, and the m
Illusion [34]

Answer: a) 84 and b ) 2084

Step-by-step explanation:

Given : Sample standard deviation : s= $22.82

(Population standard deviation is unknown ) , so we use t-test.

Critical value or the​ 95% confidence intervals :t_{n-1}*=2.0

Formula to find the sample size :

n=(\dfrac{t^*\cdot s}{E})^2

a) E = 5

n=(\dfrac{(2)\cdot 22.82}{5})^2

n=(9.128)^2=83.320384\approx84

i.e. Required sample size : n= 84

b)  E = 1

n=(\dfrac{(2)\cdot 22.82}{1})^2

n=(45.64)^2=2083.0096\approx2084

i.e. Required sample size : n= 2084

Answer:

Step-by-step explanation:

For a number to be divisible by 4 you just need to worry about the 10s and 1s place.  You also want to know that the 1s cylce every 20, or in other words:

4 8 12 16 20

24 28 32 36 40 and so on.  So the only numbers that x can be there are 1, 3, 5, 7, 9.  Does that make sense?  and can you manage  the rest?
