Answer:
540
Step-by-step explanation:
If you do 15x12 which is the formula for area for a rectangle, you get 180. That's only the area of one rectangle but if you multiply it by 3 you get 540 for the areas added together.
Answer:
540 cm
Step-by-step explanation:
you multiply 15 x12 If you are getting an area 15 x12=180 then you multiply 180 by 3 180x3=540 I think

A 3-column table with 4 rows titled 90-Day Forecast. Column 1 is labeled Weather Type with entries wind, rain, clouds, sunshine. Column 2 is labeled Predicted frequency with entries 9, 18, 27, 36. Column 3 is labeled Observed frequency with entries 12, 15, 33, 30.
The table shows the results of the experiment to determine the 90-day weather forecast. How does the experimental probability compare to the theoretical probability?
The theoretical probability for rain is 1/5. The experimental probability for rain is
.
The actual weather is

Freshman, sophomore, junior, and senior students at a high school will be surveyed regarding a potential increase in the extracurricular student activities fee. There are three possible responses to the survey question - agree with the increase, do not agree with the increase, or no opinion. A chi-square test will be conducted to determine whether the response to this question is independent of the class in which the student is a member. How many degrees of freedom should the chi-square test have
Answer:
The degrees of freedom is 6 for the chi square independence test.
Step-by-step explanation:
This is test hypothesis of independence. The test statistic under H0 is
χ²= ∑ (O - E)²/ E
where O is the observed and E is the expected frequency
which has an approximate chi square distribution with ( r-1) (c-1) degrees of freedom, where r= rows and c= columns.
Here there are 4 rows and 3 columns
Hence the degrees of freedom will be
( 4-1) ( 3-1)= 3*2= 6
-x+4=-9 help me please
Answer:
-13 = x
Step-by-step explanation:
:))
Answer: x = 13
Step-by-step explanation:
First subtract -4 on both sides because your adding by 4
-x + 4 = -9
- 4 -4
The 4 - 4 cancels out
So, -9 - 4 is -13
Then we change the sign because we cannot leave x negative.
-x = -13
x = 13

The radius of a cylindrical construction pipe is 1.5 ft. If the pipe is 15 ft long whats the volume
Answer:
Step-by-step explanation:
r = 1.5 ft
h = 15 ft
π = 3.14
Volume = πr²h
= 3.14 * 1.5 *1.5 *15
= 1.5.975 cubic feet
The radius of a cylindrical construction pipe is 1.5 ft. If the pipe is 15 ft long, what's the volume ?
Answer:-Given:-[tex] \bullet [/tex] Radius (r) of a cylindrical construction pipe is 1.5 ft.
[tex] \bullet [/tex] Height (h) of a cylindrical construction pipe is 15 ft.
To Find:-Volume of a cylindrical construction pipe.
Solution:-We know,
Formula of Volume of cylinder is πr²h.
So, Volume = 3.14 × (1.5)² × 15
Volume = 3.14 × 1.5 × 1.5 × 15
Volume = 105.975 cubic ft.
The volume of a cylindrical construction pipe is 105.975 cubic ft. [Answer]11 divided by 6 please help

Janae solved the equation 3.67 = c − 2.13 , and found the value for c. Janae's solution was c =1.54 Do you agree or disagree with her solution. Explain. Show your work. plzzz help me ill give yo a brainlyiest
Answer:
Solution;
given equation : 3.67 = c - 2.13
On solving equation, we get
c = 3.67 +2.13
c = 5.8
Hence, Janae solution is incorrect. So I disagree.
Answer: No because the answer is c =5.8 or 5.80
Step-by-step explanation:
Add 2.13 to both sides. 3.67 + 2.13 = 5.80
Selina weighs a metal sample in science class as being 20.8 grams. The actual weight of the sample is 20 grams. What is her percent relative error? Show your work.
Answer:
.04%
Step-by-step explanation:
you would subtract the 20.8 by 20 to get .8, then you divide .8 by the actual wait to get .04%

PAST DUE DATE NEED DONE NOW! NO LINKS! HELP ME FIND THE EQUATION
To write an equation for this line, you first need to understand how to derive it.
Let's utilize slope-intercept form, as it's the easiest to understand compared to any other form for line functions:
y = mx + b
m: The slope of the line
b: The y-intercept (The point where the line is at the y-axis)
Now that we've defined our variables, how do we go about making the actual equation? Let's start off with the slope, m.
The slope is a measure of how high or low the line is. The number is a ratio between the rise and run of a slope. In other words, it is essentially [tex]\frac{rise}{run}[/tex]
Let's look back at the graph. In the time interval from 1 to 2 seconds, we see that the line rises by 22 feet. Because the time interval is only 1 second, the run is 1 second.
Therefore:
m = [tex]\frac{rise}{run}[/tex]
m = [tex]\frac{22}{1}[/tex]
m = 22
We now have the first variable of the equation.
y = 22x + b
What about b? As we established earlier, b is the value of coordinate y at the y-intercept. Essentially, to find b we need to know what the value of y is when the coordinate x is 0.
As you can see from the graph you made, the value of y when x is 0 is also 0. This makes sense, too. How can the cheetah travel distance at 0 seconds when it obviously hasn't started moving? We now know b = 0. Now, we have gotten all of the variables we need to make a full equation:
y = 22x + 0
y = 22x
If you'd like me to explain how I did anything, just ask!
- breezyツ
Answer:
Equation: y=22x + 0 (you can put 0 if you want)
Step-by-step explanation:
Okay, so this is set up as a y=mx+b equation meaning that m=rate of change and b=y-intercept. If a cheetah runs 22 feet per second which is x, that means that m=22. And if 1 second is equal to 22 feet then in 0 seconds they run 0 feet, which is your y-intercept. Another way to find the rate of change (m) is by using the equation y2-y1/x2-x1 or 44-22/1 in this case. This equation is usually written as y=22x. Hope this helps!

Vertical Angles are pair of two angles opposite to each other formed by two lines intersecting each other. And they have equal measures.

Answer:
178.6 ft
Step-by-step explanation:
The definitions of the trig functions tell you ...
Cos = Adjacent/Hypotenuse
cos(69°) = FD/DE
DE = FD/cos(69°) ≈ (64 ft)/0.3584

The area of a triangle is 36 square inches. What is the height of the triangle if the base length is 8 inches? (3 points) a 8 inches b 9 inches c 12 inches d 6 inches
9514 1404 393
Answer:
b. 9 inches
Step-by-step explanation:
The area of a triangle is given by ...
A = 1/2bh
Solving for h, we get ...
h = 2A/b
h = 2(36 in²)/(8 in) = 72/8 in
h = 9 in
The height of the triangle is 9 inches.
