What is the value of x in the equation 1/5x - 2/3y = 30, when y = 15?

Answers

Answer 1

Answer:

x = (-150)/49

Step-by-step explanation:

Solve for x:

49 x + 150 = 0

Hint: | Isolate terms with x to the left hand side.

Subtract 150 from both sides:

49 x + (150 - 150) = -150

Hint: | Look for the difference of two identical terms.

150 - 150 = 0:

49 x = -150

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of 49 x = -150 by 49:

(49 x)/49 = (-150)/49

Hint: | Any nonzero number divided by itself is one.

49/49 = 1:

Answer: x = (-150)/49

On Saturday, Ms. Rivera went to the store with $50. She needed to get clothes for the gym. She bought 5 pairs of socks for $3 dollars each, then paid $25 for shorts. Thankfully, Ms. Rivera had a coupon for half off everything! How much money did Ms. Rivera go home with?

Answers

Answer:

20

Step-by-step explanation:

She bought 5 pairs of socks which are 3 dollars each

(5 times 3 = 15 )

With the 25 dollar shorts

( 25 + 15 = 40 )

with a coupon of half off

( 40 divided by 2 = 20)

No the answer is 15 she got half ofF EVERTHING so that means half the socks and the shorts price so therefore the answer is. 15

Answer:

AA Similarty

Step-by-step explanation: We are given that two angles are congruent so we use AA SImilarity. Stating that if  two angles are congruent, then the figures are similar.

The postulate that can be used to prove that triangles ABC and DEF are similar triangles is: C. AA Similarity Postulate.

What is the ​AA Similarity Postulate?

The AA similarity postulate states that when two triangles have two pairs of corresponding angles that are congruent to each other, the two triangles are regarded as similar triangles.

Thus, triangles ABC and DEF have:

two pairs of congruent angles - ∠B ≅ ∠E and ∠C ≅ ∠F.

Therefore, the postulate that can be used to prove that triangles ABC and DEF are similar triangles is: C. AA Similarity Postulate.

A DVD normally costs $22. This week it is on sale for 25% off the original price. What is the sale price of the DVD?​

Answers

Answer:

$16.5

Step-by-step explanation:

25 % of 22 is 5.5

22 - 5.5 = 16.5

The sale price of the DVD in this week on sale for 25% off on the original price is $16.5.

Given that  the original price of a DVD  is $22, that means the cost of the DVD is $22.

This week the sale on the original  price of  a DVD. The sale is that 25% off on the original price of a DVD, that is 25% off on $22.

Here, calculate the discount on the original price of a DVD.

[tex]Discount=22\times25 \%\\Discount=22\times\frac{25}{100}\\Discount=\frac{22}{4} \\Discount=\$5.5[/tex]

The discount is $5.5  on the original  price of  a DVD.

Therefore, the sale price of a DVD on this week after the discount:

[tex]Sale\ price= \$22-$5.5\\Sale\ price=\$16.5[/tex]

Thus, the sale price of a DVD is $16.5.

A wildlife biologist is doing research on chronic wasting disease and its impact on the deer populations in northern Colorado. To estimate the difference between the proportions of deer with chronic wasting disease in two different regions, a random sample of 200 deer was obtained from one region and a random sample of 197 deer was obtained from the other region. The biologist checked for the following.

(200)(0.06)≥10
(200)(0.94)≥10
(197)(0.086)≥10
(197)(0.914)≥10

Which of the following conditions for inference was the biologist checking?

a. The population of deer within each region is approximately normal.
b. It is reasonable to generalize from the samples to the populations.
c. The samples are independent of each other.
d. The observations within each sample are close to independent.
e. The sampling distribution of the difference in sample proportions is approximately normal.

Answers

Answer:e. The sampling distribution of the difference in sample proportion is approximately normal.

Step-by-step explanation:

(200) (0.06) >= 10

(200) (0.94) >=10

(197)(0.086) >=10

(197)(0.914) >= 10

We test the sample proportions of it is normal :

Deer population 1:

Sample size, n1 = 200

Proportion, p1 = 0.06

q = 1 - p = 1 - 0.06 = 0.94

n1 * p = 200 * 0.06 = 12

n1 * q = 200 * 0.94 = 188

Deer population 2:

Sample size, n2 = 197

Proportion, p = 0.086

q = 1 - p = 1 - 0.086 = 0.914

n2 * p = 197 * 0.086 = 16.94

n2 * q = 197 * 0.914 = 180.06

Since for samples and proportions ;

n*p and nq ≥ 10 ;

We cm conclude that the sampling distribution of the difference in sample mean is appropriately normal.

The sampling distribution of the difference in sample proportions is approximately normal because samples and proportions are greater than or equal to 10.

Given :

A wildlife biologist is doing research on chronic wasting disease and its impact on the deer populations in northern Colorado. A random sample of 200 deer was obtained from one region and a random sample of 197 deer was obtained from the other region.

For dear population 1, the sample size is 200 and proportion is 0.06.

[tex]\rm q_1 = 1-p_1=1-0.06=0.94[/tex]

[tex]\rm n_1p_1=200\times 0.06=12\\[/tex]

[tex]\rm n_1q_1=200\times 0.94 = 188[/tex]

Now, for dear population 2, the sample size is 197 and the proportion is 0.086.

[tex]\rm q_2 = 1-p_2=1-0.086=0.914[/tex]

[tex]\rm n_2p_2=197\times 0.086=16.94[/tex]

[tex]\rm n_2q_2=197\times 0.914 = 180.06[/tex]

Therefore, from the above calculations, it can be concluded that the sampling distribution of the difference in sample proportions is approximately normal because samples and proportions are greater than or equal to 10.

Ales read 1/3 of a book Monday. 28 pages Tuesday . still has 1/3 left to read. how many pages in book

Answers

Answer:

there are 84 pages in the book.

Step-by-step explanation:

let's call the pages in the book b.

1/3b + 1/3b + 28 = b

2/3b + 28 = b

subtract 2/3b from both sides of the equation

2/3b - 2/3b + 28 = b - 2/3b

28 = b - 2/3b

28 = b/3

multiply both sides of the equation by 3

28 * 3 = b/3 * 3

28 * 3 = b

84 = b

The correct Answer is - Fails the true premises test and passes the proper form test.

Step-by-step explanation:

Given,

The first premise is - All birds can fly

The second premise is - Penguins are birds

Conclusion - Penguins can fly

As we know that all birds cannot fly , so first premise is not true.

Penguins is a bird , it is true . So second premise is true.

As , to pass the true premise test, both premises has to be true

But here, in this question , one premise is not true

So, it Fails the true premises test.

As the argument is valid

If the premises is true , then the conclusion is valid

So, it passes the proper form test.
