Answer:
Falso.
Step-by-step explanation:
Acá tenemos la proposición:
"En una multiplicación, si un factor es un número natural y el otro es un número entero negativo, el producto es siempre menor que cada uno de los factores."
Primero tratemos de demostrar que esto es falso, para ello debemos encontrar un solo ejemplo en el que la proposición sea falsa.
Elijamos al número 1 como el número natural,
Elijamos -10 como el número entero negativo.
El producto es:
1*-10 = -10
Ahora veamos si el producto es menor que cada uno de los factores.
-10 < 1 ?
Si, -10 es menor que 1.
Ahora veamos con el otro factor:
-10 < - 10?
No, un número no puede ser menor que si mismo.
Entonces el producto no siempre es menor que cada uno de los factores.
Entonces la proposición es falsa.

KP is a radius of the circle. Is JK tangent to the circle? Note the figure may not be drawn to scale.
Answer:
JK is NOT tangent to the circle
Step-by-step explanation:
A tangent of a circle is a line that intersects a circle at one and only one point. For this reason, the radius will always intersect a tangent at a 90 degree angle to prove this single point intersection. From the triangle, we can introduce the Pythagorean theorem to see if the triangle is a right triangle:
a^2 + b^2 = c^2
48^2 + 14^2 = 36^2
2304 + 196 = 1296
2500 ≠ 1296
As this is not equal, the triangle is not a right triangle and therefore states that the tangent line does not intersect the radius at 90 degrees, meaning that it does not satisfy the requirements of a tangent line.

Determine whether the statement is true or false. If the statement is false, make the necessary change(s) to produce a true statement.
If an event is certain to occur, its probability is 1.
Answer: false
Step-by-step explanation:
An event that cannot possibly happen has a probability of zero. If there is a chance that an event will happen, then its probability is between zero and 1.
hope this helps
Yes, The statement ''If an event is certain to occur, its probability is 1'' is true.
What is mean by Probability?
The term probability refers to the likelihood of an event occurring.
Given that;
The statement is,
''If an event is certain to occur, its probability is 1.''
Now,
Since, The event that is sure to happen is called a certain event and probability of such an event is 1 as this event is bound to happen.
Thus, The statement ''If an event is certain to occur, its probability is 1'' is true.

Thirty students in an art class each receive an identical set of 20 markers. As part of a project, each student is asked to close their eyes and select from his or her set at random. You developed a model that predicts the probability of a student randomly picking a yellow marker is 0.1. Which result would most likely cast doubt on your model? (Hint: what is the theoretical probability of 30 students choosing a yellow marker each from a pack of 20 markers.)
10 student pick red markers.
10 student pick yellow markers.
2 student pick blue markers.
2 student pick yellow markers.
3 students pick yellow markers.
3 students pick green markers.
okay 1 student = 1/20 chance of picking yellow
1/20 (30/30) = 30/600 chance of picking yellow out of 30 studnets
30/600 = 0.05 = 5% chance of choosing yellow.
I each studnet picks 1 yellow marker. Is that all the options?

Answer:
35
Step-by-step explanation:
Breakeven quantity are the number of units produced and sold at which net income is zero
Breakeven quantity = fixed cost / price – variable cost per unit
Fixed costs are costs that do not vary with output. e,g, rent, mortgage payments
If production is zero or if production is a million, Mortgage payments do not change - it remains the same no matter the level of output.
Hourly wage costs and payments for production inputs are variable costs
Variable costs are costs that vary with production
fixed cost = $2450
Variable cost = $75
price = $145
(2450) / (145 - 75) = 35

find peremiter of pqr
Answer:
79.2 units
Step-by-step explanation:
Tangents to a circle from an external point are congruent , then
PQ = 27.4
QR = 5.9 + 12.2 = 18.1
PR = 12.2 + (27.4 - 5.9 ) = 12.2 + 21.5 = 33.7
Then
perimeter = PQ + QR + PR = 27.4 + 18.1 + 33.7 = 79.2
Solve central angle
Answer:
BC=48 degrees, AD= ??
Step-by-step explanation:
I'm going to find the angle BC so a full circle is 360 degrees but half of a circle is 180 degrees since we are dealing with half a circle its 180, 90 and 42 are already used so lets add these two numbers which is 132 lastly to find out the remaining which is angle BC we have to subtract 180-132 which is 48. So your first answer is 48.
Next is AD which i don't know how to do, Sorry :(

Answer:
Stanley needs 31 feet and 2 inches of fencing.
Step-by-step explanation:
In order to answer this problem, you need to find the perimeter of the dog run.
Since: [tex]P=2(l+w)[/tex]
and [tex]l=149[/tex] inches & [tex]w=56[/tex] inches
Plug in what we know :
[tex]P=2(149+56)[/tex]
and solve:
[tex]P=410[/tex] inches
The dog run has a perimeter of 410 inches.
However, now we need to subtract 36 inches since the gate doesn't need fencing.
[tex]410-36=374[/tex] inches.
The dog run needs 374 inches of fencing.
In order to find out how many feet of fencing that is, divide it by 12.
[tex]\frac{374}{12}[/tex] = 31.16666667 OR [tex]31\frac{2}{12}[/tex], meaning 31 feet and 2 inches.
Answer:
31 feet and 2 inches of fencing :))<3

True or False? Will these lengths form a triangle?
Answer:
False.
Step-by-step explanation:
Since The angle sum property of traingke is 180°.
Answer:
No, these lengths will not form a triangle.
Step-by-step explanation:
The Triangle Inequality Theorem states that the sum of two sides must always be greater than the third side.
55 + 76 = 131
131 is not greater than 112.
Therefore, these lengths will not form a triangle.

In order to increase typing speed Minisoft has redesigned its keyboard and provided a chime that is related to typing speed. The company wants to know if its innovations affect typing speed. Identify the independent and dependent variables in this proposed study. Group of answer choices The dependent variable is keyboard design; the independent variables are the speed of typing and the chime. The dependent variable is the number of errors made; the independent variables are the chime and the speed of typing. The dependent variable is the chime; the independent variables are the chime and typing speed. The dependent variable is speed of typing; the independent variables are the keyboard design and the chime.
Answer:
The dependent variable is speed of typing; the independent variables are the keyboard design and the chime.
Step-by-step explanation:
The variable which we intend to measure or determine is called the dependent or predicted variable. However, to predict or measure the dependent variable, one or more variables are required, these are the variables whose different values or input affects the outcome of the dependent variable, these variables are called the independent variable.
In the scenario described above, the dependent variable is typing speed as it is the variable we intend to measure or determine using the new keyboard design and chime as the predictor variables.

Put in order from smallest to largest: 0, 9/5, 0.25, 0.99, 1/3, 9/10, 1, 0.5
Answer:
0,0.5,9/10,0.25,1/3,0.99,1
Step-by-step explanation:
Answer:
if the smallest and the largest order is
0, 0.5, 0.25, 0.99, 1, 1/3, 9/5, 9/10
therefore:
the order from smallest is 0
the order from largest is 9/10
Which equation is TRUE?
A)
4x + 2x + 7 = 6x - 2x + 7
B)
4x + 2x = 6x - 2x
C)
5x - x + 7 = 6x - 2x + 7
D)
8x + 1 - 2x = 6X – 2x + 1
Answer:
c and d
Step-by-step explanation:
Simplify a: 6x+7=4x+7 ~ No matter what, this cannot be possible
Simplify b: 6x=4x ~ Once again, this is impossible unless x=0, but I'll assume it can't be for now
Simplify c: 4x+7=4x+7 ~ This clearly is a correct statement, this it is c
Simplify d: 6x-1=4x+1 ~ By subtracting 4x on each side, then adding 1 on both sides, we get 2x=2, so x can be 2.
