Answer: C. 6 1/6

Step-by-step explanation:

yes

The required value of the expression [tex]\frac{a + 2bc}{3a}[/tex]  is 74 / 12 or   37 / 6 .

Given that,
The expression [tex]\frac{a + 2bc}{3a}[/tex]  is given, The value of the expression at a = 4, b = -5, and c = -7 is to be determined.

Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,
The given expression
=  [tex]\frac{a + 2bc}{3a}[/tex]
At  a = 4, b = -5, and c = -7
[tex]= \frac{4 +2 * -4 * -5 }{3 * 4 } \\= 74 / 12\\= 37 / 6[/tex]

Thus, the required value of the expression  [tex]\frac{a + 2bc}{3a}[/tex]  is 74 / 12 or   37 / 6 .

Step-by-step explanation:

Answer:

The correct option is C.

C) The range represents the number of users each month for 36 months

Step-by-step explanation:

We have been given that:

x-axis ⇒ Number of Months

y-axis ⇒ Number of Users

x-axis values = 0 to 36

y-axis values = 0 to 60

We have a function which is represented by a straight line from (0,0) to (36,54).

We have to find the RANGE of the function.

Range of a function is a complete set of values of dependent variable y, for all possible values of independent variable x

As total number of months = 36

Range is the set of all values of y (Number of Users) for each month for a period of 36 months.

Hence, the correct option is C.

Answer:

c

Answer:

The approximate length of the pendulum is 46.08 ft

Step-by-step explanation:

The time (t) of pendulum oscillation is given as;

[tex]t = 2 \pi\sqrt{\frac{L}{g} }[/tex]

where;

L is the length of the pendulum

g is acceleration due to gravity = 9.8 m/s² = 32.15 ft/s²

t is the time given as 2.4 π seconds

From the equation above, make L the subject of the formula;

[tex]t = 2 \pi\sqrt{\frac{L}{g} } \\\\\frac{t}{2\pi} = \sqrt{\frac{L}{g} }\\\\(\frac{t}{2\pi} )^2 =\frac{L}{g} \\\\L = g*(\frac{t}{2\pi} )^2\\\\L = 32.15*(\frac{2.4 \pi}{2\pi} )^2\\\\L = 32.15 *1.44\\\\L = 46.296 \ ft[/tex]

Therefore, the approximate length of the pendulum is 46.29 ft

The closest option is 46.08 ft

Answer:

46.08 ft

Gross Base pay is equals to $129

Step-by-step explanation:

Gross base pay can be defined as the pay per hour which has been discussed and finalized by the employer and employee at the time of job offering. It is the minimum amount of pay the employee is to receive. The tips, bonuses, allowances are not considered in the Gross base pay. Moreover, it is the basic pay an employee gets before any kind of tax deductions..

Gross base pay can easily be calculated by multiplying the pay per hour with the number of hours worked.

Pay per hour = $8.60

Numbers of hours worked = 15

Gross Base Pay = 8.60×15 = $129

Answer:

$129 besties

======> Mathematics <=======

Step-by-step :

the sum of all angles in the triangle is 180°, So =>

180° = 50° + 60° + x

180° = 110° + x

180° - 110° = x

70° = x

Answer:

x = 5.6

Step-by-step explanation:

5x:8 = 7:2

First, find the relationship between 2 and 7.

2 x 3.5 = 7

Since the ratios are equal, this means:

8 x 3.5 = 5x

Solve algebraically. First simply 8 x 3.5

5x = 28

Divide both sides by 5

x = 5.6

Step-by-step explanation:

-2 < n+3 ≤ 4

Make two separate equations,

-2 < n+3

Subtract 3 from both sides,

-2-3 < n + 3  -3

-5 < n

So, value of n should be greater than (-5)

n +3 ≤ 4

Subtract 3 from both sides

n ≤ 1

So, n value should be less than or equal to 1

So, n value should be greater than -5 and less than or equal to 1

n= { -4, -3 , -2 , -1 ,0 ,1 }

Answer:

(-1, 8) (-5, 11)

Step-by-step explanation:

We are subtracting 3 from the x coordinate and adding 5 to the y coordinate

(2,3) becomes (2-3, 3+5) = (-1,8)

(-2,6) becomes (-2-3, 6+5) = (-5,11)

Answer:

Step-by-step explanation:

First, find the volume of the cone.

V = [tex]\frac{1}{3}[/tex][tex]\pi[/tex]r²h

V = [tex]\frac{1}{3}[/tex](3.14)(9)(12)

V = 113.04

This means the sphere is also 113.04

Use the formula V = [tex]\frac{4}{3}[/tex][tex]\pi[/tex]r³

113.04 = [tex]\frac{4}{3}[/tex](3.14)r³

113.04 = 4.19r³

Step-by-step explanation:

the modes m and n have to be data points more than 1 time, but equal

if there are 7 data points, then there are 4 unknown left/2 2 each

(2m-3+m+12+3n+2+m+m+n+n)/7=18

(3m+9+3n+2+m+m+n+n)/7=18

Answer:

5.48

Step-by-step explanation:

First, we convert all the fractions into improper fractions. 1 3/7 is 10/7, 3 5/9 is 32/9, and 1/2 stays the same. then we find a common denominator, which would be the LCM of 7, 9 and 2, which is 126. Finally, we rewrite the fractions with the common denominator of 56, and we get 180/126, 448/9 and 63/126. adding these together we get 691/126, which is approximately 5.48412698, which we can round to 5.48

D) The price of fish per pound

Step-by-step explanation:

A continuous data is one which can take any value . it can have even value between any two consecutive number.

Example :

continuous data can have value between 4 and 5 like 4.5 4.001 and so on.

Discrete data is one which can be counted such as number of flowers, no of cars in parking.

it can take value such as 1,2, 12, 66  etc.

____________________________________________

Let go through the option

A) The number of times you flip a coin

We can count the number of times a coin is flipped .

Like 2 times, 3 times and hence it is discrete data and not a continuous one.

B) The number of students in a classroom

Student in a classroom can also be counted.

in a class there can be 12, 50, 66 etc students not 12.1 , 50.5 etc.

hence it is discrete data and not a continuous one.

C) The number of chocolate candies in a box

Again, chocolate number can be counted .

Number of chocolate can be 2, 4, 5 and not 2.1 , 4.6 etc and

hence it is discrete data and not a continuous one.

D>The price of fish per pound

Price of fist cannot be counted . Further, price of fish can be $2.5 , $ 4.555

hence it is a continuous data.

Based on above discussion

continuous data is represented by The price of fish per pound
