Answer:

The price of item after successive discounts are 20% and 30% is $140.

Step-by-step explanation:

The marked price of item is $250.

Two successive discounts are 20% and 30%.

Price of item after discounts of 20% is

$250-\frac{20}{100}(250)=250-50=200$

New price of item after first discount is $200.

Price of item after second discount, i.e., 30% is

$200-\frac{30}{100}(200)=200-60=140$

Therefore, the price of item after successive discounts are 20% and 30% is $140.

Answer:

Kindly check explanation

Step-by-step explanation:

The hypothesis :

H0 : μ = 3000

H0 : μ ≠ 3000

The test statistic :

(xbar - μ) ÷ (s/√(n))

xbar = 3500

μ = 3000

σ = 300

n = 30

(3500 - 3000) ÷ (350/√(30))

Test statistic = 7.824

Df = 30 - 1 = 29

Tcritical at 0.01 = 2.462

Test statistic > critical value ; we reject H0 ; and concluded that there is significant evidence that

μ ≠ 3000

Answer:

Jill's best friend jumped 8/21 feet further than Jill.

Step-by-step explanation:

we have that

Jill jumped 6 1/3 feet

Jill best friend jumped 6 5/7 feet

To find out how much farther did Jill's best friend jumped, subtract the length that Jill jumped from the length that Jill best friend jumped

$6\frac{5}{7}-6\frac{1}{3}$

but first convert mixed number to improper fraction

$6\frac{5}{7}\ ft=\frac{6*7+5}{7}=\frac{47}{7}\ ft$

$6\frac{1}{3}\ ft=\frac{6*3+1}{3}=\frac{19}{3}\ ft$

substitute the values

$\frac{47}{7}-\frac{19}{3}=\frac{47*3-7*19}{21}=\frac{8}{21}\ ft$

therefore

Jill's best friend jumped 8/21 feet further than Jill.

Which of the following statements would be correct to use when proving that limx→4(3x−4)=8?

Fudgin [204]

Answer:

Option c

Step-by-step explanation:

given that limit x tending to 4 of the function (3x-4) is 8

This implies for all values of x such that for epsilon >0 arbitrary small ,

$||x-4||$ , we get

|f(x)-8|<3epsilon

this is equivalent to the option c.

Proof:

Consider

$||x-4||$

Hence it follows that option C is right.
