The grades on a history midterm at Gardner Bullis are roughly symmetric with μ = 69 μ=69mu, equals, 69 and σ = 3.5 σ=3.5sigma, equals, 3, point, 5. Ishaan scored 65 6565 on the exam. Find the z-score for Ishaan's exam grade. Round to two decimal places.

Answer: The slope is 5/2.  

Step-by-step explanation:

Convert the equation into slope intercept form, ( y=mx+b)  

2y = 5x + 4   Divide each side by 2

y = 5/2x + 2    In this form the slope will be the coefficient of x variable.

The coefficient is the number that comes before x.  

In this case, the slope is 5/2.

Step-by-step explanation:

Given

cost of ticket=$60

a. the cost of x tickets is

C(x)=60x

b. sale tax of 5.5% of $60 is 5.5/100*60

   0.55*60=$3.3

processing fee = $8

the total cost T(a) for a dollars spent on tickets.

T(a)=60a+3.3+8

T(a)=60a+11.3

c. Find (T ∘ C)(x).

T(x)=60x+11.3

d. Find (T ∘ C)(6)

T(6)=60*6+11.3

T(6)=360+11.3

T(6)=$371.3

This means that for 6 tickets with a tax of 5.5% and a processing fee of $8 the cost will be $371.3

Answer:

50w+20 (cm)

Step-by-step explanation:

There would be w pieces of 50cm wood pieces and one 20cm wood piece.

wood length = 50w +20

Step-by-step explanation:

Given

Length of Pieces = 50cm

Number of Pieces = w

Left over = 20cm

Required

Determine the length of the wood

Start by multiplying the number of pieces by the length of each pieces

Result = length * number

Result = 50 * w

Result = 50w

Lastly, add the leftover to get the actual length of the wood

Woodlengrh = result + leftover

Substitute 50w for Result and 20 for Leftover

woodlength = 50w + 20

Hence, the length of the wood is 50w + 20

Answer:

11 7/10 miles below sea level

Step-by-step explanation:

Given the following :

Peak of Mount everest = 5 1/2 miles above sea level

Bottom of Mariana trench = 6 9/10 miles below sea level

If mount everest is placed at the bottom of Mariana trench

. It's be will be :

Since sea level could be considered as a 0 point;

Adding the height and depth of both should give us the depth below sea level:

(6 9/10 + 5 1/2) miles

6 + 5 (9/10 + 1/2)

11 (9 + 5)/10

11 14/10

11 7/10

= 11 7/10 miles below sea level

Answer:

-6

Step-by-step explanation:

subtract 3 from both sides and that leaves 3x=-18

then divide 3 by -18 and that equals -6

Answer:

x= -6

Step-by-step explanation:

Step 1: Subtract 34 from both sides.

3x+34−34=16−34

3x=−18

Step 2: Divide both sides by 3.

3x /3  =  −18 /3

x=−6

Answer:

$135

Step-by-step explanation:

First, find the unit rate of money earned (36/8=4.5)

Then, multiply the unit rate of money earned by 30 (4.5 x 30 = $135)

I apologize if my wording is incorrect.

The total earnings for the 30 hours is $1350 if John earned $36 for 8 hours of work. Earnings are directly proportional to hours worked.

It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.

It is given that:

John earned $36 for 8 hours of work. Earnings are directly proportional to hours worked.

Earnings ∝ hours

E ∝ T

E = kT

Here k is the constant

36 = 8k

k = 36/8

E = (36/8)T

Plug T = 30

E = (36/8)(30)

E = $1350

Thus, the total earnings for the 30 hours is $1350 if John earned $36 for 8 hours of work. Earnings are directly proportional to hours worked.

Answer:

[tex]\boxed {j = -20}[/tex]

Step-by-step explanation:

-Solve for the value of [tex]j[/tex]:

[tex]20 - 17j = -18j[/tex]

-Take [tex]18j[/tex]and add it to [tex]17j[/tex]:

[tex]20 - 17j + 18j = -18j + 18j[/tex]

[tex]20 + j = 0[/tex]

-Subtract both sides by [tex]20[/tex]:

[tex]20 - 20 + j = 0 -20[/tex]

[tex]\boxed {j = -20}[/tex]

So, the value of [tex]j[/tex] is [tex]-20[/tex].

Answer:

the tripled recipe of peaches is 2 or 6/3

the tripled amount of rhubarb would be 21/2 or [tex]10\frac{1}{2}[/tex]

Step-by-step explanation:

for the first part, just multiply the top number (2) by 3. (that would be 6)

then, divide that by the bottom number (3).

6/3 = 2.

for the second part, you need to convert the mixed number to an improper fraction.

[tex]3\frac{1}{2}[/tex] as an improper fraction is [tex]\frac{7}{2}[/tex]

now, multiply the top number (7) by 3. (that would be 21)

then. divide that by the bottom number. (2)

21/2 = [tex]10\frac{1}{2}[/tex]

Answer:

Here,

Volume of pyramid (V) = 1/2 ×A×H

Given, V= 60 , H= 9

Now place the value of V and H in :

V= 1/2 ×A×H

60= 1/2 ×A × 9

60×2= 9A

120/9 = A

Hence, A= 120/9

Step-by-step explanation:

Answer:

Step-by-step explanation

Let's say d = distance, r = speed and t = time

We know the distance formula is :

distance = speed x time

d = r multiplied by t

d = rt

If the speed is 15km/hr, the time would be 30 minutes shorter.

Since d = rt,

90 = 15t

t = 6,

This means the time taken for the bus to complete the journey at 15km/hr would be 6hrs.

Originally though, the journey takes 30 minutes longer.

So we can say t = 6.5 hrs , and we know d = 90

Now we use the distance formula:

d = rt, since we want to find the original speed, we want to find r.

Speed = distance/time

r = d/t

r = 90/6.5

r = 180/13

Therefore the original speed is 180/13 km/hr
