How to find the product between two mixed numbers?

A mixed number is a number that is written as the addition of a whole number and an improper fraction.

Remember that the mixed number "negative two and one third" is written as:

-2 ¹/₃ = (-2 - 1/3)

Here we want to solve the product:

(-2 - 1/3)*(-5 - 15/100)

Notice that all the signs are negative, so the outcome will be positive:

(-2 - 1/3)*(-5 - 15/100) = 2*5 + (1/3)*5 + 2*(15/100) + (1/3)*(15/100)

                                 = 10 + 5/3 + 30/100 + 5/100

                                 = 10 + 5/3 + 3/10 + 1/20

                                  = 10 + 3/3 + 2/3 + 6/20 + 1/20

                                  = 11 + 2/3 + 7/20 = 11 + 40/60 + 21/60

                                  = 11 + 61/60 = 11 + 60/60 + 1/60 = 12 + 1/60

Then the product between the mixed numbers is equal to 12 and 1 over 60, which is the first option.

First, use the slope formula to calculate the slope.

Second, solve for the y-intercept using the slope and one of the points.

Finally, once you've determined m and b, you can enter them into the slope-intercept form of a line (y = mx + b) to obtain the equation for the line.

Step-by-step explanation:

8x + 3y = 7 --------(1)

2x + y = 2 ----------(2)

y = 2 – 2x ---------(3)

just substitute for y in equation (1)

8x + 3(2–2x) = 7

8x + 6 – 6x = 7

8x – 6x + 6 = 7

2x = 7 – 6

2x = 1

x = ½

since x = ½ just substitute for x in equation(3)

y = 2 – 2x

y = 2 – 2(½)

y = 2 – 1

y = 1

so x = ½,y = 1

Answer:

To solve a system of equations without graphing, you can use one of several methods, such as substitution or elimination. Here's how you can solve this system using substitution:

First, solve one of the equations for one of the variables in terms of the other variable. For example, you can solve the first equation for y:

5x + 14y = -5

y = (-5 - 5x) / 14

Substitute this expression for y into the second equation, to get an equation in terms of x:

-3x + 10((-5 - 5x) / 14) = 72

Simplify this equation to get an equation in terms of x:

-3x - 50 - 35x = 72

-38x - 50 = 72

-38x = 122

x = -3.316

Substitute this value for x back into one of the original equations to solve for y:

y = (-5 - 5(-3.316)) / 14

y = (5 + 16.58) / 14

y = 21.58 / 14

y = 1.546

So the solution to the system of equations is (x, y) = (-3.316, 1.546).

Alternatively, you could solve the system using elimination. To do this, you would add the two equations to eliminate one of the variables, and then solve the resulting equation for the remaining variable.

In the 2nd step, we isolate the "2hr" by subtracting both sides by 2b. This is do unto the +2b done to the right side initially. We want 2hr all by itself since it contains h.

Then to fully isolate h, we divide both sides by 2r. It might help to think of 2hr as 2r*h so you can pull out the terms easier. The division is done to undo the multiplication.

The rectangle's area is increasing at a pace of 128 in2 /s.

What in math is a rate?

A rate is a unique ratio where the two words are expressed in several units. For instance, the price is 69 for 12 ounces if a 12-ounce can of maize costs 69. This is not a proportion of two comparable units, like shirts. This ratio compares two dissimilar units: ounces and cents

Give L and W the length and breadth, respectively. The rectangle's surface area is

A = L ⋅ W.

To obtain, differentiate both sides of the aforementioned equation with regard to time t.

dA ⁄ dt = dL ⁄ dt ⋅ W + L ⋅ dW ⁄ dt

Given the circumstances,

dL ⁄ dt = 10 and dW ⁄ dt = 4

So at the moment when L = 12 and W = 2,

dA ⁄ dt = (10)(12) + 4(2 )

          = 128

What is null hypothesis?

In a scientific setting, a hypothesis (plural: hypotheses) is a testable claim about the relationship between two or more variables or a suggested explanation for a phenomenon that has been observed.

Part a

We have the following data given:

n=10 represent the sample size

[tex]$\bar{x}=40.5$[/tex] represent the sample mean

[tex]$\sigma=1.25$[/tex]represent the population deviation.

The significance level provided was [tex]$\alpha=0.05$[/tex]

[tex]p_v=P(Z > 1.265)=1-P(Z < 1.265)=1-0.897=0.1029[/tex]

For this case the probability of type II error is defined as the probability of incorrectly retaining the null hypothesis and is defined like this:

[tex]\beta=P\left(Z < z_\alpha-\frac{(x-\mu) \sqrt{n}}{\sigma}\right)[/tex]

Where [tex]$z_\alpha=1.645$[/tex]represent the critical value for the test that accumulates 0.05 of the area on the right tail of the normal standard distribution.

The true mean on this case is assumed [tex]$\mu=42$[/tex], so then we can replace like this:

[tex]\beta=P\left(Z < 1.645-\frac{2 \sqrt{10}}{1.25}\right)=P(Z < -3.409)=0.000326$$[/tex]

Part d

We want to ensure that the probability of error type II not exceeds 0.1, and for this case we can use the following formula:

[tex]n=\frac{\left(z_\alpha+z_\beta\right)^2 \sigma^2}{(x-\mu)^2}[/tex]

The possibility that an event will occur is gauged by probability. It is a mathematical idea that measures the probability or possibility that a specific event will occur. Probability is expressed as a number between 0 and 1, where 0 denotes that the event is highly unlikely to occur and 1 denotes that it will definitely happen. Making predictions and judgments based on the likelihood of an event occurring is a common use of probability in many disciplines, including statistics, economics, and gambling. The number of successful outcomes is divided by the total number of possible outcomes to determine probability. For example, if a coin is flipped and has a 50% chance of landing on heads, the probability of the coin falling on chiefs is 0.5.

The measure of ∠JKM is 145°.

The measure of an exterior angle of a triangle is bigger than either of the measures of the distant interior angles, according to the external angle theorem, Proposition 1.16 in Euclid's Elements.

Because the parallel postulate is not required for its proof, this is a fundamental conclusion in absolute geometry. Three of a triangle's corners are its vertices.

Two angles are produced by a triangle's sides (line segments) meeting at its apex (four angles if you consider the sides of the triangle to be lines instead of line segments). An interior angle of the triangle is the only one of these angles that has the third side of the triangle inside of it.

Here it is given that, ∠JLK= 70°

                                 ∠LJK = x°

(2x-5)°= 70°+x°

now applying exterior angle theorem,

x=75°

substitute 75 for x in 2x-5 to find m∠JKM.

=2x-5
