The value of E(Y) and Var(Y) are 50 and 178/5 respectively
Temperatures measurementGiven the formula for temperature conversion expressed as:
Y = (9/5)*X + 32
where:
X stands for a temperature in degrees Celsius,
Y the same temperature in degrees
If E(X) = 10, then;
Y = (9/5) * 10 + 32
Y = (9*2) + 32
Y = 18 + 32
Y = 50
Hence E(Y) = 50
If Var(X) = 2
Y = (9/5) * 2 + 32
Y = 18/5 + 32
Y = 178/5
Hence Var(Y) = 50
The value of E(Y) and Var(Y) are 50 and 178/5 respectively

An angle measures 134° less than the measure of its supplementary angle. What is the measure of each angle?
Answer:
23° and 157°
Step-by-step explanation:
Let n represent the smaller angle then the larger angle would be...
n+134
Supplementary angles add up to 180 degrees. We can use this information to set up an equation...
n+n+134=180
Combine like terms
2n+134=180
Subtract 134 from both sides
2n=46
Divide both sides by 2
n=23
n+134=157
23° and 157°
-3(x+4) I have no idea
Answer:
The simplified version of this equation is -3x - 12.
Step-by-step explanation:
To simplify this equation, distribute -3 to both x and 4.
-3(x+4) = -3x -12
Answer:
-3x-12 as an expression
Step-by-step explanation:
To solve this problem, we need to distribute!
Multiply -3 by both the x and the 4
When we do this, we get:
-3x and -12
Note: when you multiply a positive by a negative, you get a negative so it turns into a negative number
Note 2: When you see an x without a number in front of it, it becomes 1x. In this problem, that is why it is a -3x because -3 x 1 is -3

A coral reef grows 0.19m every week. How much does it grow in 14 weeks? Write your answer in centimeters.
Answer:
The coral reef grows 266 cm in 14 weeks.
Step-by-step explanation:
Lets convert 0.19 meters to centimeters.
1m= 100cm
0.19m×100= 19 cm
It grows 19 cm every week, so:
[tex]\frac{1w}{19 cm} *14 =\frac{14w}{x= 266 cm}[/tex]
So, the coral reef grows 266 cm in 14 weeks.

Are this functions yes or no how can I tell if it is ?
Answer:
yes they are all functions
Step-by-step explanation:
Despite f(x) being the classic way to write a function,
a function has:
an input (domain)a relationship (maps to)an output (range)A function relates each element of a set with exactly one element of another (possibly the same) set.
One-to-one and many-to-one are functions, but one-to-many is not a function.
You can also carry out the Vertical Line Test on a graph. If the vertical line only crosses the curve once, it is a function. If it crosses more than once it is still a valid curve, but is not a function.
Yes they all are functions
Functions should include
Two variables (Here they are x and f(x))Must have domain and range.Function must return a new value as output when any input is given .PLEASE HELP ASAP! I have no idea where to start with this.
Answer:
h (-5) = 41/4 or 10.25
h (-2) = -3
h (3) = 25/4 or 6.25
Step-by-step explanation:
h (-5) = 1/4(-5)^2 + 4
h (-5) = 1/4(25) + 4
h (-5) = 41/4 or 10.25
h (-2) = -3 (this is given to you in the function)
h (3) = 1/4 (3)^2 + 4
h (3) = 1/4(9) + 4
h (3) = 25/4 or 6.25

Answer:
A, the first option, 49 square cm
Step-by-step explanation:
[] To know
-> A squares sides are all the same size
-> The area of a square can be found by finding L * W
[] Solving
-> We can use the points given to solve for one side, EF, of the square
-> Both the x coordinates are the same, so we can subtract the y values as they are on the same line.
6 - -1 = 6 + 1 = 7
-> Now for the area

15. Sensei's Judo Club has a competition for
the students. If you win a grappling match,
you are awarded 5 points. If you tie, you
are awarded 2 points. Jeremy grappled 15
times and his score was 48 points. How
many grapples did Jeremy win?
Answer:
6 grapples
Step-by-step explanation:
x = number of wins
y = number of ties
y = 15 - x
48 = 5x + 2y
48 = 5x + 2(15 - x)
48 = 5x + 30 - 2x
48 = 3x + 30
18 = 3x
x = 6
The number of grapples that Jeremy win will be 6.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
Sensei's Judo Club has a competition for the students.
Let x be the number of wins and y be the number of ties.
If you win a grappling match, you are awarded 5 points.
Then the equation will be
x + y = 15
y = 15 - x
If you tie, you are awarded 2 points.
Jeremy grappled 15 times and his score was 48 points.
Then the equation will be
5x + 2y = 48
Put the value of y in the above equation. Then we have
5x + 2(15 - x) = 48
5x + 30 - 2x = 48
3x = 18
x = 6
The number of grapples that Jeremy win will be 6.

The perimeter of a square is 48 millimeters. What is its area?
Explanation:
The perimeter is 48 mm. We divide that by 4 to find the side length of the square, since each side is the same length.
48/4 = 12
Each side is 12 mm long.
This means the area of this square is 12^2 = 12*12 = 144 square mm

Answer:
C) 471
Step-by-step explanation:
Surface area for a cylinder formula:
SA = 2πrh + 2πr²
Given:
r = 5
h = 10
Work:
SA = 2πrh + 2πr²
SA = 2(3.14)(5)(10) + 2(3.14)(5²)
SA = 314 + 2(3.14)(25)
SA = 314 + 157

store per month?

C = 970n + 14.60
ос
C = 14.60n +970
Od
C = 10.50n +970
Answer: I think the answer b
Step-by-step explanation:
The cost function for Julia's clothing store per month is 14.60n +970
What is function?A function is defined as a relation between a set of inputs having one output each.
Given that, Julia is opening a clothing store. She plans to start by selling sweatshirts. It costs her $10.50 for each sweatshirt, $4 per box for the shirts, and $0.10 a bag. Julia also spends $900 on rent, $40 on electricity, and $30 on advertising each month.
There are two types of cost Julia have,
The variable cost that is not fixed and depend on how many shirts she's making, = $10.50+$4 +$0.10 = $14.60
Let she makes n shirts, so cost = $14.60n
And the second one is fixed cost that is cost she is spending on rent, electricity and advertising, = $900+$40+$30 = $970
Therefore, cost = 14.60n +970
Hence, the cost function for Julia's clothing store per month is 14.60n +970

Use the area of a triangle in coordinate geometry formula:
[tex]\triangle GHI =\frac{1}{2} |x_1(y_2- y_3) + x_2(y_3 -y_1) + x_3(y_1 -y_2)|[/tex]
