A store in Minnesota advertises that on a holiday, everything is 20% off. A person buys shoes for $40 and socks for $10. In Minn

posledela

The final price is $ 40

Solution:

A store in Minnesota advertises that on a holiday, everything is 20% off

Discount = 20 %

A person buys shoes for $40 and socks for $10

Therefore, Total price before discount is given as:

Total price = 40 + 10 = 50

Therefore,

Total price before discount = $ 50

Discount = 20 %

Therefore, discount price is 20 % of 50

$Discount\ price = 20 \% \times 50\\\\Discount\ price = \frac{20}{100} \times 50\\\\Discount\ price = 10$

Thus the discount price is $ 10

Final price is given as:

Final price = Total price before discount - discount price

Final price = 50 - 10 = 40

Thus the final price is $ 40

For the following pairs of assertions, indicate which do not comply with our rules for setting up hypotheses and why (the subscr

torisob [31]

Answer:

Options B, C, D & E do not comply with the rules for setting up hypotheses

Step-by-step explanation:

(A). H0: m = 100, Ha: m > 100.

These hypotheses fully complies with our rules.

B). H0: s = 20, Ha: s 20.

H0 is not an equality claim such as σ = 20. Hence, these hypotheses are not in compliance with our rules.

(C). H0: p -:: .25, Ha: p = .25

H0 should definitely contain the equality claim, although Ha contains it here. Thus, these are not legitimate and don't comply with our rules

(D)H0: m1 - m2 = 25, Ha: m1 - m2 > 100

The given value of 25 for m1 - m2 in H0 should also appear in Ha,but it does not do so here, so it doesn't comply with our rules.

E)H0: S2 = S2, H : S2 -:: S2

Each S2 is a statistic and so it does not belong in a hypothesis.

A Farm raises pigs and chickens. The farmer has a total of 66 animals. One Day he Counts the legs of all his animals and realize

Bogdan [553]

Answer: Pigs = 21

Chicken = 45

Step-by-step explanation:

Let the pigs be represented by p

Let the chicken be represented by c.

From the question,

p + c = 66

4p + 2c = 174

4 × ( p + c = 66)

1 × (4p + 2c = 174)

4p + 4c = 264

- 4p + 2c = 174

2c = 90

c = 90/2 = 45

There are 45 chickens

Simce the farmer has a total of 66 animals, the number of pigs will be:

= 66 - 45

= 21 pigs
