What is -1/2 (-5/6 plus 1/3) simplified
Answer:
0.25 or 5/12 - 1/6
Step-by-step explanation:
-1/2(-5/6+1/3), do PMDAS. (-5/6) = -0.833 (repeated) and (1/3) = 0.333 (repeated) and you add them both (-0.833 + 0.333) = -0.5 and -1/2 = -0.5 and when you multiply them both it would equal 0.25. or another explanation for the answer is 5/12 = 0.41666666666 and 1/6 = 0.16666666666 and when you subtract them both you get 0.25, I hope this was helpful.

If x and y vary inversely and x = 5 when y = -3.5, what is the value of x when y = 10?
Answer:
Step-by-step explanation:
k = xy
Putting values of x and y in the equation
k = (5)(-3.5)
= - 17.5
Finding value of x when y = 10
k = xy
- 17.5 = x10
Bringing like terms on one side
- 17.5 - 10 = x
-27.5 = x
about liner equations!! please help with answer
Answer:
There are infinitely many solutions
Step-by-step explanation:
The expressions on both sides of the equation are the same, that is
[tex]\frac{1}{2}[/tex] (b + 14) is the same as [tex]\frac{b+14}{2}[/tex]
Thus the equation has infinitely many solutions
The diameter of a circle is 14 ft.
What is the area of the circle in terms of π?
Answer:
49π ft²
Step-by-step explanation:
[tex]A=\pi r^2[/tex] where r is the radius of the circle
To find the radius, divide the diameter by 2:
14 ft ÷ 2 = 7 ft
Plug the radius 7 ft into the equation
[tex]A=\pi (7)^2\\A=49\pi[/tex]
Therefore, the area of the circle in terms of pi is 49π ft².
I hope this helps!
Answer:
49π
Step-by-step explanation:
Diameter=14
Radius=14/2=7
Area=πr squared
Area=7 squared π
Area=49π
At the Fisher farm, the weights of zucchini squash are Normally distributed. Which standardized weight represents the top 10% of the zucchinis?
Find the z-table here.
–1.64
–1.28
1.28
1.64
Thus, the standardized weight which represents the top 10% of the zucchinis from the z-table for the fisher farm is 1.28.
How to get the z scores?If we've got a normal distribution, then we can convert it to standard normal distribution and its values will give us the z score.
[tex]Z = \dfrac{X - \mu}{\sigma}[/tex]
Here, X is sample, is μ mean and is σ standard deviation.
At the Fisher farm, the weights of zucchini squash are Normally distributed.
For the normal distribution let the value of mean is 0 and standard deviation 1. Thus,
[tex]Z = \dfrac{X - \mu}{\sigma}\\Z = \dfrac{X - 0}{1}\\Z=X[/tex]
For the top 10% of the zucchinis, the value of α is 0.9. From the table for this value the z score is,
[tex]Z=X=1.28[/tex]
Thus, the standardized weight which represents the top 10% of the zucchinis from the z-table for the fisher farm is 1.28.

Hey can you help me fast!!
Answer:
I believe the answer would be -4 1/2.
help me do this plz brainiest to whoever right
there are two machines that can produce aluminum cans. The newer machine can produce 5400 cans in 180 minutes. It takes the older machine 217 minutes produce that many cans. If the two machines work together, how long will it take them to produce 5400 cans?
The newer machine works at a unit rate of
(5400 cans) / (180 min) = 30 cans/min
while the older machine operates at
(5400 cans) / (217 min) ≈ 24.88 cans/min
So working together, the two machines work at a rate of about 54.88 cans/min. Producing 5400 cans would then take about
(5400 cans) / (54.88 cans/min) ≈ 98.39 min

Find the area of the shape
Answer:
54 unit^2.
Step-by-step explanation:
The area = the sum of the 2 triangles.
Area of a triangle = 1/2 * base * height.
So here:
A = 1/2 * 4 * 12 + 1/2 * 5 * 12
= 24 + 30
= 54
Answer:
ABCD = 54 u²Explanation:
the area of the polygon = the area of the triangle ADC + the area of the triangle ABC
the area of a triangle = (height × base)/2
A ADC = (DE×AC)/2
A ADC = (4×12)/2
A ADC = 48/2
A ADC = 24 u²
A ABC = (BF×AC)/2
A ABC = (5×12)/2
A ABC = 60/2
A ABC = 30 u²
ABCD = A ADC + A ABC
ABCD = 24 + 30
ABCD = 54 u²

Kat is interested in getting chickens so she can have fresh eggs. Before she buys her chickens, she wants to find the mean number of eggs each one will lay. She begins by randomly selecting 40 chickens from a large poultry farm and counts how many eggs each one lays within one month. She finds the mean to be 24.8 eggs with a standard deviation of 6.9 eggs. The resulting interval is (22.96, 26.64). Which of the following correctly interprets the 90% confidence interval for the true mean number of eggs chickens from this poultry farm lay within one month?
90% of all chickens at this farm lay between 22.96 and 26.64 eggs.
In repeated sampling, 90% of the time the true mean number of eggs chickens at this farm lay is 24.8.
Kat can be 90% confident that the constructed interval (22.96, 26.64) captures the true mean number of eggs chickens from this farm lay.
In repeated sampling, 90% of the time the true mean number of eggs laid by chickens from this farm will be captured within the interval (22.96, 26.64).

The students in two 7th grade classes were asked, "How many text messages did they send over the past weekend?" The data was collected and a dot plot was created for each class. For what values do class A's distribution and class B's distribution overlap?
Answer:
2, 3, 4, and 5
Step-by-step explanation:
Class A and Class B's distributions overlap for the values of 2, 3, 4, and 5. This can be seen in the dot plot below since all of these values have inputs on both of the class' distributions. Values 0 and 1 are not included because they only have inputs for Class A, while values 6 and 7 are not included because they only have inputs for Class B. In order for the values to overlap they need to be included in both class distributions.
Answer:
2,3,4,5
Step-by-step explanation:
Class A and Class B distribution overlap at 2,3,4 and 5 because if you look at both graphs you can see how they both overlap each other.

Manchester United during their championship 2012 - 2013 season. They won matches where they scored
more goals than their opponent, lost matches where they scored less, and tied matches where they scored the
same amount.

this subset?
Choose all answers that apply:
CA
The subset consists of all the matches where Manchester United's opponent did not win.
B)
The subset consists of all the matches where Manchester United won or lost.
