Answer: 1 1/12 feet
Step-by-step explanation:
When Dalvin runs the 400 meter dash, his finishing times are normally distributed with a mean of 65 seconds and a standard deviation of 1 second. Using the empirical rule, what percentage of races will his finishing time be between 64 and 66 seconds?
Answer:
68%.
Step-by-step explanation:
Dalvin's finishing time is normally distributed with a mean of 65 seconds and a standard deviation of 1 second.
Under the empirical rule, 68% of the results will be within 1 standard deviation.
Since the standard deviation is 1 second, 68% of Dalvin's finishing time will be between 64 and 66 seconds.

Answer:
37
Step-by-step explanation:
The angle with a red square is 90, because it's a right angle. 53 + 90 is 143. 180 is the sum of all the angles in a triangle, so you do 180-143. 180-143=37
Answer:
37
Step-by-step explanation:
90+53=143
a triangle is 180 degrees.
180-143=37

Answer: C: cubic expression
Step-by-step explanation:
Classify the expression: 5x³ + 2x − 3
we know that
Polynomials can be classified two different ways - by the number of terms and by their degree.
so
a) By the number of terms is a trinomial, because has three terms
b) By their degree The degree of the polynomial is found by looking at the term with the highest exponent on its variable
The highest exponent is 3 so this is a 3rd degree trinomial
therefore
Is a cubic expression

PLEASE HELP!!!!!!!!!!!!!!!!!!!!!!!!!!
Can somebody tell me the answer to this please
Answer: D
Step-by-step explanation: We first need to solve the inequality.
First subtract 10 from both sides to get -x < -8.
Now divide both sides by -1, but watch out.
If you multiply or divide both sides of an inequality by
a negative number, you must switch the direction of the inequality sign.
So we have x > 8.
Start with an open dot at 8 and draw and arrow to the right.
We use an option dot since x is greater than but not equal to 8.
So option D is your answer.
Answer:
The correct answer is D

3x − x − 1 = 15
What is x
Answer: x=8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3x−x−1=15
3x+−x+−1=15
(3x+−x)+(−1)=15(Combine Like Terms)
2x+−1=15
2x−1=15
Step 2: Add 1 to both sides.
2x−1+1=15+1
2x=16
Step 3: Divide both sides by 2.
2x /2 = 16 /2
x=8
Answer:
3x-x=15+1
2x=16
x=16/2
x=8

express 4.67 as a mixed number
Answer:
4.671 = (4.67 × 100)(1 × 100) = 467100.
Step-by-step explanation:
As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 467100 is also equal to 467100 when expressed as a mixed number.
Answer:
4 67/100
Step-by-step explanation:
From the info we have, we now that the whole number is 4.
.67 ends in the hundredths place which means it will be a decimal over 100.
Now you have 67/100 and since 67 is prime it can't be simplified.
Put them together and you get 4 67/100

Which of the following equations are equations of a direct variation? Choose all that apply.
(a) x=−2y
(b) x+2y=12
(c) 3x−2y=0
(d) 5x^2+y=0
(e) y =0.3x +1.6
(f) y−2=x
Answer:
(a) x = -2y
(c) 3x - 2y = 0
Step-by-step explanation:
You can tell if an equation is a direct variation equation if it can be written in the format y = kx.
Note that there is no addition and subtraction in this equation.
Let's put these equations in the form y = kx.
(a) x = -2y
y = x/-2 → y = -1/2x This is equivalent to multiplying x by -1/2, so this is an example of direct variation.(b) x + 2y = 12
2y = 12 - x y = 6 - 1/2x This is not in the form y = kx since we are adding 6 to -1/2x. Therefore, this is NOT an example of direct variation.(c) 3x - 2y = 0
-2y = -3x y = 3/2x This follows the format of y = kx, so it is an example of direct variation.(d) 5x² + y = 0
y = -5x²This is not in the form of y = kx, so it is NOT an example of direct variation.(e) y = 0.3x + 1.6
1.6 is being added to 0.3x, so it is NOT an example of direct variation.(f) y - 2 = x
y = x + 2 2 is being added to x, so it is NOT an example of direct variation.The following equations are examples of direct variation:
x = -2y 3x - 2y = 0Answer:
(a) x = -2y
(c) 3x - 2y = 0
Step-by-step explanation:
You can tell if an equation is a direct variation equation if it can be written in the format y = kx.
Note that there is no addition and subtraction in this equation.
Let's put these equations in the form y = kx.
(a) x = -2y
y = x/-2 → y = -1/2x
This is equivalent to multiplying x by -1/2, so this is an example of direct variation.
(b) x + 2y = 12
2y = 12 - x
y = 6 - 1/2x
This is not in the form y = kx since we are adding 6 to -1/2x. Therefore, this is NOT an example of direct variation.
(c) 3x - 2y = 0
-2y = -3x
y = 3/2x
This follows the format of y = kx, so it is an example of direct variation.
(d) 5x² + y = 0
y = -5x²
This is not in the form of y = kx, so it is NOT an example of direct variation.
(e) y = 0.3x + 1.6
1.6 is being added to 0.3x, so it is NOT an example of direct variation.
(f) y - 2 = x
y = x + 2
2 is being added to x, so it is NOT an example of direct variation.
The following equations are examples of direct variation:
x = -2y
3x - 2y = 0

The zurn family ate at a restaurant that was having 15% discount on that day .Their meal costs 64.75,and they left a 20% tip .What is the total cost of the meal
Answer:
[tex]66.05[/tex]
Step-by-step explanation:
Cost of meal = [tex]64.75[/tex]
Cost of meal after discount of [tex]15\%[/tex]
[tex]64.75-64.75\times 0.15[/tex]
[tex]=64.75(1-0.15)[/tex]

Kathy uses 8.6 pints of blue paint and white paint to paint her bedroom walls. 4 5 of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls?
Answer:Kathy uses 1.72 pint of white paint
Step-by-step explanation:
Total amount of paint ( Blue and white paint)= 8.6 pints
Amount of blue paint=4/5 x 8.6 = 6.88 Pints
amount of white paint = Total amount of paint - amount of blue paint
= 8.6 pints - 6.88 pints
=1.72 pint of white paint
