To subtract mixed numbers with different denominators, follow these steps:

1. Rename the fractions using a common denominator.

2. Subtract whole numbers from whole numbers. You might need to regroup first.

3. Subtract fractions from fractions.

4. Simplify, if needed.

Let's try it with [tex]2\frac{3}{5}-1\frac{1}{4}[/tex]

First, rename the fractions using a common denominator. The least common denominator of these fractions is 20. Multiply to make equivalent fractions with 20 as the denominator.

[tex]\frac{3x4}{5x4}=\frac{12}{20}[/tex]        [tex]\frac{1x5}{4x5}=\frac{5}{20}[/tex]

Rewrite the problem and subtract the whole numbers.

[tex]2\frac{12}{20}-1\frac{5}{20}=1\frac{?}{?}[/tex]

Now, subtract the fractions. Subtract the numerators and keep the denominator the same.

[tex]2\frac{12}{20}-1\frac{5}{20}=1\frac{7}{20}[/tex]

This answer is already in its simplest form, so there is no need to simplify it.

Answer:

x = 8

y = 11

Step-by-step explanation:

Total small box weight  = 50x    [x being the number of small boxes]

Total large box weight = 80y     [y being the number of large boxes]      

Total boxes = x+y = 19

Total weight = 1280

Determine x and y.

You know 2 equations. One for weight and another for number of boxes each.

Rewrite second equation:

x+y=19

y=19-x

You have to plug in one into another.

1280 = 50x + 80(19-x)

Solve for x

1280 = 50x + 1520 - 80x

-240 = -30x

x = 8

Solve for y by plugging in x into one of the equations:

8+y = 19

y = 11

Answer:

Step-by-step explanation:

An equation is formed of two equal expressions. The missing pieces of the solution of the quadratic equation are 50, 3, and -8.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

To fill the missing piece of the solution of the quadratic equation, you need to balance each of the equations. Therefore, the solution to the problem can be written as,

[tex]-32 = 2(x^2 + 10x)\\\\-32 + 50 = 2(x^2 + 10x + 25)\\\\18 = 2(x + 5)^2\\\\9 = (x + 5)2\\\\\pm 3= x + 5\\\\x = -2\ \ {\rm or}\ \ x = -8[/tex]

Thus, the solution of the quadratic equation is -2 or -8.

Hence, the missing pieces of the solution of the quadratic equation are 50, 3, and -8.

===============================================

Explanation:

The tangent function is being applied to some unknown angle x. To isolate x, we undo whatever tangent is doing. So we apply the inverse function. Specifically the inverse tangent function. This is also known as "arctangent" and your calculator most likely shows it as a button with a "-1" exponent above the "tan"

So apply the arctangent to both sides to get

tan(x) = 0.7773

arctan(tan(x)) = arctan(0.7773)

x = 37.8579

Step-by-step explanation:

Step 1:  Determine what negative association is

Negative association basically means that the best-fit line for the scatter plot would be in a downwards slope which means that it has a negative association.  

In the given examples, Option A wouldn't work because we can see that the best-fit line would be going up which is a positive association.  Option B would work because we see the downward slope.  Option C wond't work for the same reason as Option A.  And finally Option D would work since we have a downward slope.

Ahh, yes, the Pythagorean Theorem!

The Pythagorean Theorem is applied to right triangles. Only right triangles. So our answer would be B.

I hope this makes sense. I can continue to expand on this if you like.

The correct answer is option (B) Right triangle.

A triangle with one of its angles measuring 90° is known as a right triangle.

The Pythagorean theorem is applicable only to a right triangle.

The Pythagorean theorem states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the legs of the triangle.

Hence, the correct answer is option (B) Right triangle.

Step-by-step explanation:

The most restrictive level of significance that would suggest the company should raise rates is a p-value less than or equal to 0.01.

Hypothesis testing is a statistical method that is used to make decisions about a population based on a sample of data.

It involves testing a null hypothesis (H0) against an alternative hypothesis (Ha) using statistical techniques.

We have,

To determine if the increase in the average cost per claim is statistically significant, we can perform a hypothesis test.

Let's use a one-sample t-test, where:

Null hypothesis (H0): The average cost per claim is still $2,200.

Alternative hypothesis (Ha): The average cost per claim is greater than $2,200.

We can use a t-test because we have a sample mean, sample size, and population standard deviation.

The test statistic is calculated as:

t = (sample mean - hypothesized mean) / (standard deviation/√ (sample size))

Plugging in the values given, we get:

t = (2350 - 2200) / (500 / √(40))

t = 4.38

Using a t-table with degrees of freedom (df) = 39 (sample size - 1), we can find the p-value associated with this test statistic.

At the 0.01 level of significance (most restrictive level), the critical t-value is 2.704.

Since our calculated t-value is greater than the critical t-value, we reject the null hypothesis and conclude that there is evidence to suggest that the average cost per claim has increased.

Therefore,

The most restrictive level of significance that would suggest the company should raise rates is a p-value less than or equal to 0.01.

It is a square, Hannah is a G.

Step-by-step explanation:

You can plug it in for visual, see attachment. You can see that it is a bit rotated square.

But real proof should be done with the points.

For it to be square all sides need to equal each other.

What's the x distance of M and A?

It is 1-(-5) = 1+5 = 6

What is the x distance of H and T?

It is 0-(-6) = 0+6 = 6

What is the y distance of M and H?

It is 2-(-4) = 2+4 = 6

What is the y distance of A and T?

It is 3-(-3) = 3+3 = 6

All are 6 so all sides are equal so it is a square.
