Given the info in the picture is a and b parallel?

Answer:

$57500

Step-by-step explanation:

Given data

Initial cost of desk= $50,000

Percent increase=15%

=15/100*50,000

=0.15*50,000

=$7500

Hence the new price is 7500+50,000

=$57500

Answer:

5/8 + 7/12

Step-by-step explanation:

Miles to friends house = 5/8

Ditance to the movies = 7 1/2

To find the total distance walked in Wal, we sun the fraction of distance Evans walked to his friend's house and the distance walked from friend's house to the movies ;

That is :

5/8 + 7/12

= 29/24 miles

But because you're multiplying a positive and a negative, the answer will be negative leaving you with (-15.58)

Answer:

C.

f(x) = 0.34 + 0.21(x – 1); $.97

Step-by-step explanation:

In 2002, the price of mailing a letter was $.34 for the first ounce and $.21 for each ounce after the first ounce. Write a rule to describe the function.

---------------------------------------

Price = 0.34 + 0.21(x-1) where x is the weight of the item in ounces.

Let +x+ = weight of the letter in ounces

Let +P+ = the price of mailing the letter in dollars

---------------------------------------

+P+=+.34+%2B+.21%2A%28+x+-+1+%29+

( +x+%3E=+1+ )

-----------------------------

A 4-ounce letter costs

+P+=+.34+%2B++%28+4+-+1+%29%2A.21+

+P+=+.34+%2B+.63+

+P+=+.97+

It costs $.97

Answer:

a

Step-by-step explanation:

Answer:

i. 1/4

ii. 54/125

iii. 1107/5000000

iv. 1/50

Step-by-step explanation:

i.

25% = 0.25

0.25 = 25/100

25/100 (GCF 25) = 1/4

ii.

43.2% = 0.432

0.432 = 432/1000

432/1000 (GCF 8) = 54/125

iii.

0.02214% = 0.0002214

0.0002214 = 2214/10000000

2214/10000000 (GCF 2) = 1157/5000000

iv.

2% = 0.02

0.02 = 2/100

2/100 (GCF 2) = 1/50

Answer:

x2 + x + 1

Step-by-step explanation:

A polynomial with integer coefficients that cannot be factored into polynomials of lower degree , also with integer coefficients, is called an irreducible or prime polynomial . Example 1: x2+x+1. (:

hey someone else has already answered this!

a. To find the least squares regression equation for a group of (x,y) points:

Step 1: For each point(x,y), we need to calculate x² and xy first.

Step 2: Sum all x, y, x² and xy, which gives us Σx, Σy, Σx² and Σxy

Step 3: Calculate Slope m: m = (NΣxy − Σx Σy)/ N(Σx²) − (Σx)² , here N is the number of data.

Step 4: Calculate Intercept b: b = Σy − m(Σx)/ N

Step 5: Assemble the equation as y= mx+b

Here, we have ∑x = 120, ∑y= 1379, ∑x²= 919.5, ∑xy= 10466 and N= 16

So, m= (NΣxy − Σx Σy)/ N(Σx²) − (Σx)²

=

=

=  

= 6.33

and b = Σy − m(Σx)/ N

=

=

=

= 38.71

So, the least squares regression equation is : y= mx+b ⇒ y= 6.33x +38.71

b. When x= 8, then y= (6.33×8)+38.71 = 50.64 + 38.71 =89.35

The approximate test score of a student who sleeps an average of 8 h a night is 89.35%

EVERYTHING IS FROM sicista on brainly!

Answer:

A way to write the least regression equation that models is data y = mx + b => y= 6.33x + 38.71 and as for problem B when X = 8 then y = (6.33 x 8) + 38.71 = 50.64 = 38.71 = 89.35 so the estimated test score of a student who sleeps eight hours a night is equal to 89.39%

Answer:

The 3 liter bottle has a better deal

Step-by-step explanation:

Which bottle is a better deal?

For the 2 liter bottle

At one store, a 2-liter bottle of soda costs $2.12.

2 liter bottle = $2.12

1 liter bottle = x

Cross Multiply

2x = $2.12

x = $2.12/2

x = $1.06

Hence, this is $1.06 per liter

For the 3 liter bottle

At another store, a 3-liter bottle costs $3.15.

3 liter bottle = $3.15

1 liter bottle = x

Cross Multiply

3x = $3.15

x = $3.15/3

x = $1.05

Hence, this is $1.05 per liter

Therefore, the bottle which is a better deal is the 3 liter bottle because, 1 liter goes for $1.05

Answer: 7x - 5

Step-by-step explanation:

The expression given in the question is:

Step-by-step explanation:

The 4th girls answer was 2

The fourth girl danced with two of boys.

Two or more expressions with an Equal sign is called as Equation.

Given,

At a party there were 4 boys and 4 girls.

Boys only danced with girls and girls only danced with boys.

In boys, first boys dance with  3 girls

Second boy danced with one girl

Third boy danced with two girls

Fourth boy danced with two girls

3+1+2+2=8

When comes to four girls, three girls said they danced with two boys.

We need to find with how many boys fourth girl danced.

2+2+2+x=8

x+6=8

x=2

Hence, the fourth girl danced with two of boys.
